Project Name: NAVY REDEVELOPMENT
Location: 1727 and 1737 Pearl Street
Size of Property: 0.32-acres (14,111 square feet)
Zoning: Downtown 2 (DT-2)
Comprehensive Plan: Regional Business (RB)
KEY ISSUES:
Staff has identified the following key issues to help guide the board’s discussion:
1. Does the project meet the applicable Site Review criteria in Section 9-2-14(h), B.R.C. 1981?
2. Is the proposed project consistent with the Downtown Urban Design Guidelines for the Non-Historic and
Interface Areas?
PROCESS
The applicant has elected to undergo a Site Review. The purpose of Site Review is to allow flexibility and encourage
innovation in land use development. Per Table 2-2 of the land use code a Concept Plan and Site Review are required in the
DT-2 zone district for projects of one acre or 50,000 square feet of floor area. The proposal meets the thresholds for
voluntary site review. The applicant has not requested any modifications to the city’s land use code that would require a
mandatory Planning Board hearing. However, given the level of public interest, staff is referring this site review request to
Planning Board for a public hearing and decision.
Design Advisory Board. The property is subject to the Downtown Urban Design Guidelines and requires review by the
Design Advisory Board (DAB). DAB reviews and applies the guidelines on all projects with a construction value over
$25,000 in the Non-Historic and Interface Areas. The board reviewed the proposal against the Site Review Criteria and the
applicable design guidelines at meetings on Mar. 6, 2019 and Sep. 11, 2019. The project review occurred twice due to the
change in scope to include an additional parcel and increased building square footage. The agenda packet, meeting
minutes, meeting audio, and other related materials are available in the city records archive for DAB at the links above.
Refer to Attachment C for staff’s analysis of the current design against the DAB comments.
BACKGROUND
The 0.32-acre project site is located north of and adjacent to Pearl Street, between 17th and 18th Streets. Refer to Figure 1
on the following page. The site is located approximately 2.5 blocks east of the Pearl Street Mall, on the eastern edge of the
Downtown area. Downtown is one of the city’s three regional activity centers identified within the Boulder Valley
Comprehensive Plan with the highest level of intensity within the city
The property is not within a historic district but is located within the Central Area General Improvement District (CAGID) and
Downtown Boulder Business Improvement District (BID). CAGID provides parking and related improvements and
maintenance in a 35-block area encompassing Downtown. The BID provides enhancements and services (economic vitality,
marketing and enhanced maintenance) in the roughly the same area as CAGID to supplement services provided by the city.
I. INTRODUCTION AND BACKGR OUND

Zoning. The project site is located in the Downtown 2 (DT-2) zone district, which is defined as: “A transition area between
the downtown and the surrounding residential areas where a wide range of retail, office, residential, and public uses are
permitted. A balance of new development with the maintenance and renovation of existing buildings is anticipated, and
where development and redevelopment consistent with the established historic and urban design character is encouraged"
(Section 9-5-2(c)(3)(A), B.R.C. 1981). Refer to Figure 6 on the following page for the zoning map.
Agenda Item 5A Page 5 of 360
Figure 6: Zoning Districts
Area Plans. The site is within the Interface Area of Downtown Boulder and is subject to the Downtown Urban Design
Guidelines. The Interface Area is located on the northern, western, and eastern borders of Downtown. The Interface Area
includes a wide variety of residential buildings. The area is composed of the blocks that link the core of the Downtown to the
surrounding residential neighborhoods. This area requires special design sensitivities that must be addressed when
commercial buildings are located adjacent to residential areas. The urban design objectives for the Non-Historic and
Interface Areas, among others, are to reinforce the character of Downtown as a pedestrian place by encouraging
architectural solutions that are visually pleasing, reflective of contemporary times yet stylistically appropriate to the context,
and compatible in scale and character with their street. Refer to Key Issue #2 for staff’s analysis of the proposal against the
Downtown Urban Design Guidelines.
Surrounding Neighborhood. The project site is
located in the eastern extension of the Pearl Street
mall commercial district, within downtown zoning. This
portion of Pearl Street contains a variety of retail,
restaurant, residential, and office uses characterized by
a compact urban character. The building immediately
to the east of the site is a one-story brick building that
contains a bicycle shop and restaurant (Full Cycle)
(Figure 7). The building immediately to the west is
three stories and 38 feet in height and contains retail
(Sherpani), apartments, restaurant (Laughing Goat
Coffeehouse), and office uses (Figure 8). The block
also contains a two-story structure at the corner of 17th
Street and Pearl Street. Across Pearl Street are two-
and three-story buildings with a mix of restaurant,
office, financial institutions, and residential uses.
Figure 7: Adjacent Use to the East
Agenda Item 5A Page 6 of 360
To the east of the subject site along Pearl Street between 18th and 24th Streets is a corridor of MU-3 zoning commonly
known as the “East Pearl” district, which contains a variety of retail, restaurant, and office uses mixed with residential uses.
To the north and south of the East Pearl corridor are primarily residential uses, with the area to the south containing
primarily high and mixed- density residential uses.
Figure 8: Adjacent Uses to the West
The Whittier neighborhood is located to the north of the site within the Residential - Mixed 1 district, which is a historic
residential neighborhood. The area to the north of the site is characterized by primarily single-family homes, constructed in
the late 1800s and early 1900s. Two single family homes, two-stories in height, immediately abut the site across the alley.
Refer to Figure 9.
Figure 9: Adjacent Residential Uses to the North
Agenda Item 5A Page 7 of 360
Land Use. The proposal is for a mixed-use development with ground floor commercial uses (9,439 square feet) and
residential units located on the second and third floors. The development is proposed to contain 8 one-bedroom units (562
to 678 square feet in area) and 6 two-bedroom units (1,210 to 2,424 square feet in area). Ten units would be for rental and
the remaining four units for sale. The current proposal is for retail space on the ground floor, which is a permitted use in the
DT-2 zone district. However, other uses like restaurants, brewpubs, and taverns or financial institutions could be added
subject to the requirements of Sections 9-6-5(b)(1), 9-6-5(b)(4), and 9-6-7(a)(4), B.R.C. 1981.
Site Plan. The site design follows the
traditional building orientation established
by the area as a main street type, with zero
foot front yard and side yard setbacks. The
building is oriented toward Pearl Street and
is designed to enhance the pedestrian
experience with storefront windows and
pedestrian scale building details. The Pearl
Street façade is broken up by a paseo
connecting to an interior courtyard. The third
story is setback to reduce the perceived
height and outdoor deck space is proposed.
Through the Site Review process, the
applicant is requesting modifications to the
form and bulk standards of the land use
code to allow a 10-foot front yard setback
from the street for the third story, where 15-
feet is required, and a 0-foot side yard
setback from an interior lot line for the third
story, where 12-feet is required. The
building is setback 15 feet from the alley. A
loading/delivery area, utility meters,
detention/water quality planters, and trees
are proposed along the alley. The existing
overhead power lines will be placed
underground.
Architecture and Building Design. The building is three stories and 38 feet in height, with below grade parking. The
building design is contemporary with neo-traditional elements. Storefront windows are proposed along Pearl Street.
Commercial spaces open onto Pearl Street. The storefronts have large display windows . Traditional elements like wood
column detailing and goose-neck light fixtures and signage make the project compatible with the Downtown Pearl Street
character. The fenestration and proportions on the second and third floors communicate the residential use but with modern
sill, jamb and lintel treatments reminiscent of the historic patterns of downtown Boulder. A two-story entry element breaks up
the main façade along Pearl Street, with a paseo that continues into and through the building to a courtyard. The applicant
II. Project Description
Figure 10: Site Plan
Agenda Item 5A Page 8 of 360
has requested a modification to the building design standards for buildings in the DT-2 zone district to allow 50% of the
ground floor façade facing a public street to be transparent materials, where 60% is required. The modification meets the
intent of the design standards since the open paseo will activate the pedestrian experience.
Figure 11: View from Across Pearl St
The third story is set-back from the front facade to reduce the perceived height. The mass is setback 10 feet from Pearl
Street on the east and west edges and 15 feet in the center portion. The applicant has requested a modification to allow the
10-foot front yard setback from the street for the third story, where 15-feet is required. The variation in setbacks in this
portion of the building adds visual interest and the reduction in setback does not significantly impact the perceived height of
the building. The structure will be built out of cast in place concrete. Stucco (three coat system), concrete masonry units
(CMU), wood look laminate cladding, and cement board siding are also used in select locations. The concrete will present a
stone-like quality or depth. The color palette is proposed to be dark blue at the base and white above, with dark window
mullions, railings and accent elements. The structure meets the intent of the design guidelines for the Non-Historic &
Interface Areas with a building that is reflective of the character of its own time with meaningful juxtapositions and
respecting the integrity, scale, and massing of historic buildings in the surrounding areas.
Open Space Areas. The proposal includes the provision of an interior courtyard with access from a paseo to Pearl
Street, private roof decks and balconies for the residential use, and landscaping in the alley. Each residential unit has either
a private balcony, some on the exterior of the building and some facing the interior courtyard, or a rooftop deck facing Pearl
Street. The courtyard is open to the sky and provides accessible open space off of Pearl Street as well as access to light
and air for the residences above. The courtyard contains an ornamental tree to anchor the center of the court and provide
shade and an enhanced “feature wall”. The proposed courtyard will be a flexible space with movable seating that will allow
for small gatherings, etc. that will be enjoyed by the residents, occupants, and visitors. Outdoor seating for a restaurant use
could spill into the interior courtyard or onto Pearl Street, with a revocable permit from the city. The alley will be landscaped
with two trees and a number of shrubs that will be located in the water quality/detention planters. All open spaces will
receive a mixture of sun and shade based on the building orientation.
Agenda Item 5A Page 9 of 360
Figure 12: Perspective of the Courtyard
Density/Intensity. The intensity of development in the DT-2 zone district is controlled by a minimum open space and a
maximum floor area ratio. The proposal is for 28,222 square feet of floor area, which amounts to a 2.0:1 floor area ratio
(FAR). Pursuant to Section 9-9-11(c) of the land use code any building over 35 feet but less than 45 feet in height shall
provide at least 15 percent of the total land area as useable open space. The minimum open space has been exceeded with
2,611 square feet of usable open space (19 percent). In addition, 60 square feet of private open space is required for each
residential unit, which is being provided as balconies and rooftop decks (Table 8-1, B.R.C. 1981).
Access and Parking. As described above, the plan includes one point of ingress/egress to parking off the alley. Public
access is provided on Pearl Street. Residents and their guests, and employees of the development can access the building
via the alley. One vehicular parking space is required for each attached dwelling unit, for a total of 14 required spaces. No
parking is required for the nonresidential uses since the site is located within CAGID. The below grade parking garage
contains 13 standard size parking spaces, one compact space, and 4 tandem spaces. An auto elevator is proposed to
provide access to the parking garage, which reduces area necessary for a ramp and allows for additional area for parking
spaces. The 15th & Pearl Public Parking Garage is located about two blocks west of the site. Metered parking is located
along Pearl, 17th, and 18th streets. The Whittier Neighborhood Permit Parking Program (NPP) is located to the north, where
public parking is limited to three hours 8 a.m. to 8 p.m. Monday to Friday.
Figure 13: View of Alley at 18th Street
Agenda Item 5A Page 10 of 360
In terms of bicycle parking, the proposal includes 40 long-term secure spaces for residents, guests, and employees of the
commercial uses in the secured parking garage, where 24 spaces are required. No short-term bike parking will be provided
on the site. However, 12 short-term bike spaces will be provided adjacent to the site along Pearl Street on inverted "u"
bicycle racks. Staff finds that the provision of bike parking in the public right-of-way is preferable to providing in the rear of
the building off the alley, since short-term parking is intended to offer a convenient and accessible area to park bicycles for
customers and other visitors.
Traffic Impact Analysis. A Trip Generation and Assignment Report has been submitted by the applicant, which
concludes that the proposed development can be accommodated by the existing roadway network without significant
impacts to service levels (refer to Attachment A). Per the City’s Design and Construction Standards, a traffic impact study
is not required for the project because the trips generated by the development will not exceed the threshold of 20 vehicle
trips during the AM or PM peak hour.
Parking Management. The submitted parking management plan describes the management of the auto elevator and
the prevention of vehicles queuing in the alley right-of-way and obstructing vehicle circulation within the alley. A
delivery/auto queueing area is provided next to the elevator entry for vehicles waiting for the elevator in the event that it is
occupied. The requirement to utilize the waiting area will be communicated to the apartment renters in their leasing package
and to the condominium owners in their operations manual. The development will maintain an ongoing fund for an auto
elevator’s maintenance service contract to ensure that the elevator will be repaired in a timely manner, if necessary.
Transportation Demand Management. The proposal includes a robust transportation demand management plan
(refer to Attachment A). Since the property is located in CAGID employees of the commercial uses will be eligible for the
downtown employee EcoPass program. In addition, an alternative transportation fund will be established for the residential
units for a period of three years to cover the costs of EcoPasses or other programs that support and encourage alternatives
to the single-occupant vehicle. The site is highly accessible, with transportation facilities and a large number of destinations
that can be reached within a 15-minute walk (grocery stores, parks, restaurants, and transit stops). There are existing bus
stops on Pearl Street near the intersection with 18th Street. The Downtown Boulder Bus Transit Station is less than half a
mile to the southwest. This regional transit center is served by at least 15 local and regional transit lines. The site is well
connected to the larger multi-modal network with detached sidewalks, designated bike routes, and bike lanes.
Refer to the applicant’s submittal materials in Attachment A for more information about the proposal.
Staff has identified the following key issues to help guide the board’s discussion:
1. Does the project meet the applicable Site Review criteria in Section 9-2-14(h), B.R.C. 1981?
2. Is the proposed project consistent with the Downtown Urban Design Guidelines for the Non-Historic and Interface
Areas?
Key Issue #1: Does the project meet the applicable Site Review criteria in Section 9-2-14(h),
B.R.C. 1981?
Staff finds that the proposed project, including the proposed modifications, meets all applicable Site Review criteria. The
project is compatible, contextual, and in character with that of the interface area of east end of downtown along Pearl Street.
The proposal meets the intent of the Regional Business land use designation with a mix of uses and a design that will
III. KEY ISSUES ANALYSI S
Agenda Item 5A Page 11 of 360
activate the street. The open spaces are appropriate considering the urban context and proximity to the pedestrian mall.
The private balconies and decks and public courtyard are accessible, functional and meet the anticipated residents,
occupants, tenants and visitors of the property.
The proposed project is an urban configuration of the building adjacent to the pedestrian walkway, which enhances the
pedestrian experience. Ground floor storefront windows, building entries, and detailing helps to establish continuity in the
established human scale along Pearl Street. The below grade parking garage and auto elevator makes efficient use of the
land and ensures the safety, convenience, and separation of pedestrian and bicyclist movements from vehicular
movements.
Figure 14: Aerial View from Southeast
The building’s height, mass and scale, and overall appearance is compatible with the surrounding context. The intent of the
DT-2 zoning is to encourage “development and redevelopment consistent with the established historic and urban design
character.” The location of the site is within the established urban context. While the existing urban design character is
eclectic, there are buildings in the surrounding area that have comparable characteristics. While the BVCP designates all of
the downtown zoning districts (DT districts) as “Regional Business” with a high level of intensity, the interface area of East
Pearl requires special design sensitivities when commercial or mixed use buildings are located adjacent to residential areas.
The urban orientation of the planned three-story, 38-foot high building is compatible with the character of the area where
two- and three-story buildings occur to the east and west along Pearl Street in the DT-2 district. There are several buildings
within a two-block radius of the subject site that are three stories, both within the DT-2 zoning district as well as the adjacent
MU-3 zoning district. Refer to Figure 15 on the following page. Likewise, the height of the proposed building is in general
proportion to the height of existing buildings in the immediate area.
Please refer to Attachment B for staff’s complete review and analysis of the Site Review Criteria.

Agenda Item 5A Page 13 of 360
Key Issue #2: Is the proposed project consistent with the Downtown Urban Design Guidelines for
the Non-Historic and Interface Areas?
Staff finds that the proposal is consistent with the applicable Downtown Urban Design Guidelines. As described above, the
subject site is subject to the guidelines for the Interface Area. The Interface Area is located on the northern, western, and
eastern borders of Downtown and is composed of the blocks that link the core of the Downtown to the surrounding
residential neighborhoods. Generally, staff finds that the proposal meets the design objectives by promoting a human-
scale development that reinforces the character of Downtown as a pedestrian place and with a building design that is
reflective of contemporary times yet stylistically appropriate with traditional references. Staff finds the proposal consistent
with the objectives, design elements, and guidelines as follows.
• The site is in an urban context and the new building will reflect that context and traditional urban design pattern by
building up to the public right-of-way on Pearl Street. The building design is contemporary with traditional
references. The base of the structure is emphasized with added wood details around the storefront window
openings. Per the applicant, more modern storefront proportions like a tall and open first floor and large display
windows are married with more traditional elements like wood column detailing at the retail level and goose-neck
light fixtures and signage. The building design will activate the pedestrian experience and reinforce the character
of the east end of Downtown along Pearl Street as a pedestrian place. The building will be setback 15 feet from
the alley and the proposal is sensitive to the transition to the residential uses across the alley.
Agenda Item 5A Page 14 of 360
• The building is set at the lot line on Pearl Street (zero setback), which maintains the historic building setback on
the north side of the 1700 block of Pearl Street. The site is located on the east edge of downtown and constrained
views toward the Flatirons is typical for this area and has been since the town was established. Since the building
is located on the north side of the street the public realm of Pearl Street will be unshaded by the proposal. Existing
mature street trees along the Pearl Street frontage will remain and provide shading of the walk and on-street
parking. All planned open spaces within the development will receive a mixture of sun and shade, including the
public courtyard.
• Mechanical equipment and utility boxes will be located in the alley. Rooftop mechanical equipment is expected to
be low in profile and will not impact the views of the upper floors of neighboring buildings. The proposal represents
four-sided design. The alley elevation features emphasized building entrances, planning areas, and alley trees.
Residents and their guests, and employees of the development can access the building via the alley. Overhead
utility lines will be placed underground as part of the proposal. Thus, the overall appearance of the alley façade will
be greatly improved from the existing condition.
• The parking is provided below grade with access from an auto elevator. The entrance to the garage is integrated
into the building design. The interior courtyard will be programmed for passive use but could also be utilized for
active purposes for residents, occupants, tenants, and visitors to the site. Outdoor seating for a restaurant use
could spill into the interior courtyard or onto Pearl Street, with a revocable permit from the city
Agenda Item 5A Page 15 of 360
• The proposal is for a main street type, mixed-use building with ground floor retail and upper floor residential units
designed in a contemporary style with neo-traditional elements. The poured in place concrete will have a stone-like
quality or depth. The contemporary building features traditional storefront elements and sill, jamb and lintel
treatments that recall historic patterns of downtown Boulder.
• The proposed three-story building 38 feet in height is compatible with the character of the area where two- and
three-story buildings occur to the east and west along Pearl Street in the DT-2 district. The proposal will maintain a
variety of heights along the Pearl Street frontage. The third story is set-back from the front facade to reduce the
perceived height. The building’s planned third story is setback 15 feet for the majority of the building’s street face
along Pearl Street but punctuated with 10 foot setbacks on the third story on the east and west edges of the
building.
• Design details and fenestration are appropriate to the pedestrian scaled context. The use of ground floor storefront
windows, wood column detailing, and traditional proportions in the building layout and fenestration helps to
establish continuity in the established human scale along Pearl Street. The paseo also provides a visual
connection through the building to an open court in the center of the building. There is an appropriate rhythm
proposed for the building’s fenestration with a repetition or sequencing of visual interest for the pedestrian. The
fenestration and proportions of the upper floors are distinct from the ground floor and communicate the residential
use.
Agenda Item 5A Page 16 of 360
IV. PUBLIC COMMENT AND PROCESS
• Primary entrances are constructed at grade, particularly to the commercial spaces along Pearl Street. Wood
column detailing on the ground level along Pearl Street maintain the traditional storefront rhythm. The ground floor
height is taller than upper stories (approximately 14 feet) and clearly distinguished as described above. The
building design allows for awnings to be placed along Pearl Street by individual commercial tenants.
Consistent with Section 9-4-3, Public Notice Requirements, B.R.C. 1981, staff provided notification to all property owners
within 600 feet of the subject location of the application, and signs have been posted by the applicant indicating the review
requested. Written public notice was sent on December 4, 2018 and July 10, 2019. The applicant held two neighborhood
meetings to introduce the proposal to interested persons in the surrounding neighborhood and to solicit input. The meetings
were held on January 28, 2019 and October 28, 2019 at the Main Boulder Public Library. Staff received several public
comment letters in response to the required public notices and sign postings for the site review, which are found in
Attachment D.

Written Statement for 1737 Pearl Street Site Review Application
06/28/2019
REVISED 07/08/2019
REVISED 03/30/2020 (See Underlined Text)
CURRENT OWNERSHIP:
The project is owned by 1737 Pearl LLC. The managing member is Adam Wertz, a resident of Boulder.
DESCRIPTION OF PROPOSAL:
1737 Pearl Street is a 14,111 SF property on the north side of Pearl Street near the corner of 18th Street and is zoned
DT-2. The property has one existing one-story building and one existing two-story building which will be demolished
to make room for the new thee-story mixed-use building proposed. The existing building uses include retail and
restaurant uses, Little Buddha Import, Top Hat Suppy, Red Letter Books and L’Atelier. Under the DT-2 zoning, this
development proposes a total of 10 new residential units on the second floor; 4 units on the third floor; along with
retail and retail service on the ground floor. A new sub grade parking garage is proposed with 14 standard size
parking spaces, 4 tandem spaces, a number of storage spaces, and service and mechanical spaces. The parking
garage will be accessed from the alley via an auto elevator at the ground floor. A loading/delivery area, the gas and
electric service and gear, detention/water quality planters and trees are all proposed along the alley. The existing
overhead power lines will be undergrounded with this proposal.
ARCHITECTURAL CHARACTER:
The proposed building will have a strong retail base to reinforce Pearl Street’s pedestrian environment and character.
As recommended by the Downtown Design Guidelines, the vertically proportioned windows on the 2nd and 3rd floors
will have modern sill, jamb and lintel treatments that recall historic patterns of downtown Boulder. A strong cornice
will end the building at the top and add detail where it meets the sky. The main façade element along Pearl Street is
a modern two-story piece that calls attention to the entrance of the exterior public paseo that continues into and
through the building to an open public court in the center of the building that is open to the sky. This court provides
accessible open space to the public off of Pearl Street as well as access to light and air for the residences above.
The third story is set back from Pearl Street 10’ – 15’ to reduce the perceived mass of the building and to be sensitive
to the adjacent residential zones. The color palette is anticipated to be dark blue at the base and white above. That
color palette will differentiate the building from the monotonous red brick buildings around it. Dark window mullions,
railings and accent elements will add detail and visual interest to the simple, elegant Pearl Street façade.
DEVELOPMENT SCHEDULE:
The owner anticipates beginning construction immediately upon the receipt of a building permit from the City of
Boulder, and completing the building within 18 months after starting construction.
COPIES OF ANY SPECIAL AGREEMENTS, CONVEYANCES, RESTRICTIONS, OR COVENANTS THAT WILL
GOVERN THE USE, MAINTENANCE, AND CONTINUED PROTECTION OF THE GOALS OF THE PROJECT AND
ANY RELATED PARKS, RECREATION AREAS, PLAYGROUNDS, OUTLOTS, OR OPEN SPACE:
None.
RESPONSE TO GENERAL CRITERIA FOR ALL SITE REVIEW APPLICATIONS (9-2-14(h))
I. Boulder Valley Comprehensive Plan:
ATTACHMENT A
Agenda Item 5A Page 20 of 360
www.theSTUDIOarchitecture.com - 1350 Pine Street | Suite 1 | Boulder | CO | 80302 - 866 | 529 | 9130
(A) How is the proposed site plan consistent with the land use map and the service area map and, on balance, the
policies of the Boulder Valley Comprehensive Plan?
The site is located in the Regional Business land use district in Zone 1 of the BVCP. The DT-2 zoning and land use
allows for a mix of residential and commercial uses along Pearl Street in downtown Boulder. The proposal includes a
mix of residential and commercial uses to support the continued health and vibrancy of the downtown area.
(B) The proposed development shall not exceed the maximum density associated with the Boulder
Valley Comprehensive Plan residential land use designation. Additionally, if the density of existing residential
development within a 300 foot area surrounding the site is at or exceeds the density permitted in the Boulder Valley
Comprehensive Plan, then the maximum density permitted on the site shall not exceed the lesser of:
(i) the density permitted in the Boulder Valley Comprehensive Plan, or,
(ii) the maximum number of units that could be placed on the site without waiving or varying any of the
requirements of Chapter 9-7, "Bulk and Density Standards," B.R.C. 1981.
How is the proposed site plan consistent with the above density criteria?
The proposed development proposes 14 new residential units on a 0.32 acre site, a density of 43.75 units per acre.
The proposed development meets the density permitted in the BVCP.
(C) How does the proposed development’s success in meeting the broad range of BVCP policies consider the
economic feasibility of implementation techniques required to meet other site review criteria?
The proposal provides much needed for-sale and rental housing in Boulder by providing 4 for-sale units and 10 rental
units in the downtown area. It will also contribute to the inclusionary housing fund by providing cash-in-lieu money as
opposed to on-site affordable housing. New residential units in this area will help reduce SOV trips and traffic by
placing residents near services and amenities in downtown. The commercial space improvements on the ground
floor will continue to improve the economic vitality of the east Pearl Street corridor. The proposed architectural
character is generally consistent with the Downtown Design guidelines and a major improvement over the character
of existing single story building that will be demolished. The proposal reinforces Boulder’s goal to continue its
compact pattern of growth which is consistent with both the zoning and the density advocated by the land use code
and BVCP.
II. Site Design:
Projects should preserve and enhance the community's unique sense of place through creative design that respects
historic character, relationship to the natural environment, and its physical setting. Projects should utilize site design
techniques which enhance the quality of the project. In determining whether this subsection is met, the approving
agency will consider the following factors:
(A). Open space, including, without limitation, parks, recreation areas, and playgrounds:
1. How is useable open space arranged to be accessible and functional, and how does it incorporate quality
landscaping, a mixture of sun and shade and places to gather?
The public court on the ground level will be a destination for pedestrians and a unique place for people to gather
along East Pearl Street. A tree will anchor the center of the court and provide shade when needed, while thoughtful
lighting and a unique “feature wall” will provide comfort and interest to the space. The commercial spaces will open
onto Pearl Street and an exterior patio along the sidewalk could be created for potential future restaurant uses.
2. How is private open space provided for each detached residential unit?
Agenda Item 5A Page 21 of 360
www.theSTUDIOarchitecture.com - 1350 Pine Street | Suite 1 | Boulder | CO | 80302 - 866 | 529 | 9130
Sizeable roof decks and balconies are provided for all residential units on both floors. The balconies and roof decks
that face south are either recessed in to the building mass or are provided with sun shading devices to make them
more usable and enjoyable. See attached plans for more open space details, dimensions and configurations.
3. How does the project provide for the preservation of natural features, including, without limitation, healthy long-
lived trees, terrain, significant plant communities, threatened and endangered species and habitat, ground and
surface water, wetlands, riparian areas, and drainage areas?
This proposal is in an urban area with no natural features.
4. How does the open space provide a relief to the density, both within the project and from surrounding
development?
The public court on the ground level will be a destination for pedestrians and a unique place for people to gather
along East Pearl Street. A tree will anchor the center of the court and provide shade when needed, while thoughtful
lighting and a unique “feature wall” will provide comfort and interest to the space. The commercial spaces will open
onto Pearl Street and an exterior patio along the sidewalk could be created for potential future restaurant uses
5. How does the open space provide a buffer to protect sensitive environmental features and natural areas?;
Not applicable.
6. If possible, how is open space linked to an area- or a city-wide system?
There are a number of parks within two to three blocks of the site. Specifically, there is the Pearl Street Mall, Barker
Park, Emma Gomez Martinez Park, the Spruce Pool and Fitzpatrick Park, not to mention the Whittier Elementary
School grounds.
(B) Open Space in Mixed Use Developments: Developments that contain a mix of residential and non-residential
uses:
1. How does the open space provide for a balance of private and shared areas for the residential uses and common
open space that is available for use by both the residential and non-residential uses that will meet the needs of the
anticipated residents, occupants, tenants, and visitors of the property?
On an urban site like this, the sidewalk along Pearl Street is the primary open space amenity for tenants and their
customers. The public court that is proposed will provide a more intimate place for both residents and visitors to enjoy
and experience. See above for more information related to private open space for residents and their guests.
2. How does the open space provide active areas and passive areas that will meet the needs of the anticipated
residents, occupants, tenants, and visitors of the property and how is the open space compatible with the
surrounding area or an adopted plan for the area?
The residents will be provided with private open space on to which they may expand their living spaces outdoors.
The proposed public court will be a flexible space with movable seating that will allow for small performances, small
gatherings, extending the retail spaces outdoors, etc. that will be enjoyed by the residents and occupants, as well as
the larger neighborhood.
(C) Landscaping:
1. How does the project provide for aesthetic enhancement and a variety of plant and hard surface materials, and
how does the selection of materials provide for a variety of colors and contrast and how does it incorporate the
preservation or use of local native vegetation where appropriate?
Agenda Item 5A Page 22 of 360
www.theSTUDIOarchitecture.com - 1350 Pine Street | Suite 1 | Boulder | CO | 80302 - 866 | 529 | 9130
A variety of planters and enhanced hardscape materials will be provided at all roof decks for residential units. These
will be designed to be compatible with the architecture and enhance the livability of each unit. Special attention will
be given to the way they soften the outdoor space, provide privacy and create an enjoyable environment for
relaxation, entertainment and dining. The landscaping in the public court will provide visual interest as the tree and
ground cover changes colors throughout the year, while the patterns in the concrete will give the space a more
human scale. The alley will be landscaped as well, with two trees and a number of shrubs that will be located in the
water quality/detention planters.
2. How does the landscape and design attempt to avoid, minimize, or mitigate impacts to important native species,
plant communities of special concern, threatened and endangered species and habitat by integrating the existing
natural environment into the project?
There are no important native species or plant communities of special concern on the existing building. The existing
street trees along Pearl Street will remain.
3. How does the project provide significant amounts of plant material sized in excess of the landscaping
requirements of Sections 9-9-12 and 9-9-13, "Landscaping and Screening Requirements," and "Streetscape Design
Standards," B.R.C. 1981;
Refer to the landscape drawings for specific plant quantities. We will be providing landscaping in excess of the
requirements with the landscaping that is proposed along the alley and within the public court.
4. How are the setbacks, yards, and useable open space along public rights-of-way landscaped to provide attractive
streetscapes, to enhance architectural features, and to contribute to the development of an attractive site plan?
The 15’ building setback along the alley will be landscaped with trees, shrubs, and planters. The existing street trees
on Pearl Street will remain, and landscaping is proposed within the public court.
(D) Circulation, including, without limitation, the transportation system that serves the property, whether public or
private and whether constructed by the developer or not:
1. How are high speeds discouraged or a physical separation between streets and the project provided?
Vehicles can only access the site from the alley. There are no driveways or roads on the property.
2. How are potential conflicts with vehicles minimized?
Vehicles can only access the site from the alley.
3. How are safe and convenient connections accessible to the public within the project and between the project and
existing and proposed transportation systems provided, including without limitation streets, bikeways, pedestrian
ways and trails?
The site is accessible to pedestrians and bicyclists from the sidewalk on Pearl Street and the alley ROW.
4. How are alternatives to the automobile promoted by incorporating site design techniques, land use patterns, and
supporting infrastructure that supports and encourages walking, biking, and other alternatives to the single occupant
vehicle?
A TDM plan is proposed that would support and promote the use of alternative transportation in a variety of
ways.
We propose to exceed both the long-term bicycle parking requirements and the short-term bicycle parking
requirements established by the City.
Agenda Item 5A Page 23 of 360
www.theSTUDIOarchitecture.com - 1350 Pine Street | Suite 1 | Boulder | CO | 80302 - 866 | 529 | 9130
5. Where practical and beneficial, how is a significant shift away from single- occupant vehicle use to alternate modes
promoted through the use of travel demand management techniques?
Please refer to the TDM plan submitted with the Site Review Application
6. What on-site facilities for external linkage with other modes of transportation are provided, where applicable?
Not Applicable
7. How is the amount of land devoted to the street system minimized?
There is no on-site street system.
8. How is the project designed for the types of traffic expected, including, without limitation, automobiles, bicycles,
and pedestrians, and how does it provide safety, separation from living areas, and control of noise and exhaust?; and
Traffic entering and leaving the proposed development will do so through the alley. We have placed residential units
on the 2nd and 3rd floors to separate them from noise and exhaust.
9. How will city construction standards be met, and how will emergency vehicle use be facilitated?
City construction standards will be met by following the Design and Construction Standards where applicable.
Emergency vehicles will have access to the project’s buildings from Pearl Street and the alley if necessary.
E. Parking:
1. How does the project incorporate into the design of parking areas, measures to provide safety, convenience, and
separation of pedestrian movements from vehicular movements?
All of the parking is accessed from the alley. Pedestrian walkways and lighting have been carefully located to
provide safe, and convenient access from the building to the parking areas. During queueing residents will wait in
the delivery / auto queueing area when waiting for the auto elevator. This will be communicated to the apartment
renters in their leasing package and to condo owners in their operations manual.
2. How does the design of parking areas make efficient use of the land and use the minimum amount of land
necessary to meet the parking needs of the project?
The proposal places the parking underground and utilizes a compact auto elevator in lieu of a typical parking ramp to
reduce the amount of area dedicated to cars and vehicular circulation.
3. How are the parking areas and lighting designed to reduce the visual impact on the project, adjacent properties
and adjacent streets?
The parking is located below ground to reduce its visual impact from Pearl and 18th Street. Lighting has been
designed with luminaires that provide for adequate safety and security while reducing light pollution that allows for an
environmentally sensitive nighttime atmosphere for both the proposed development and adjacent properties.
4. How do the parking areas utilize landscaping materials to provide shade in excess of the requirements in
Subsection 9-9-6(d), and Section 9-9-14, “Parking Lot Landscaping Standards,” B.R.C. 1981?
No parking lot landscaping is provided since we are not building a parking lot. All lighting will meet DCS standards.
(F) Building Design, Livability and Relationship to the Existing or Proposed Surrounding Area:
1. How is the building height, mass, scale, orientation, architecture and configuration compatible with the existing
character of the area or the character established by adopted design guidelines or plans for the area?
Agenda Item 5A Page 24 of 360
www.theSTUDIOarchitecture.com - 1350 Pine Street | Suite 1 | Boulder | CO | 80302 - 866 | 529 | 9130
The proposed building character generally follows the recommendations of the Downtown Design Guidelines for the
Interface Zone. The building will not exceed the maximum 38’ height allowed in DT-2 zone. The full 15’ setback along
the alley will be provided. The floor area on the third floor is setback from Pearl Street to reduce the scale of the
building.
2. How are the height of buildings in general proportion to the height of existing buildings and the proposed projected
heights of approved buildings or approved plans or design guidelines for the immediate area:
Our three story, 38’ tall proposal is compatible with the height and scale of buildings in the surrounding DT zones and
adjacent buildings along Pearl Street. We are asking for a modification from the allowed two stories to three stories
through the site review process, but the building will never exceed the allowed 38’ in this zone.
3. How does the orientation of buildings minimize shadows on and blocking of views from adjacent properties?
The 15’ building setback along the alley will reduce shadows on the neighbors to the north, and the third floor is set
back along Pearl Street to maximize view corridors along Pearl.
4. If the character of the area is identifiable, how is the project made compatible by the appropriate use of color,
materials, landscaping, signs, and lighting?
The surrounding area does not have an identifiable material palette, and the character is of a mostly traditional
storefront architecture. The proposed building uses a simple palette of materials that emphasize the base of the
structure with added wood details around the storefront window openings. More modern storefront proportions like a
tall and open first floor and large display windows are married with more traditional elements like wood column
detailing at the retail level and goose-neck light fixtures and signage will make this project compatible with the
Downtown Pearl Street character. A slightly more modern fenestration proportion is used on the upper floors to
emphasize the residential use. The character of the proposed architecture pushes more modern with the two-story
accent element in the center of the Pearl Street façade that is located and detailed to emphasize the entrance to the
paseo that leads to the public court.
5. How do buildings present an attractive streetscape, incorporate architectural and site design elements appropriate
to a pedestrian scale, and provide for the safety and convenience of pedestrians?
The proposed building uses a simple palette of materials that emphasize the retail base of the structure for a more
pedestrian-friendly scale. Traditional storefront elements like a tall first floor, large display windows and goose-neck
light fixtures and signs will make this project compatible with Downtown Boulder’s Pearl Street character. Lighting is
designed to meet and exceed the standards of the City of Boulder and as such, will not only “fit in,” but it will enhance
the character of the building and safety of pedestrians.
8. For residential projects, how is noise minimized between units, between buildings, and from either on-site or off-
site external sources through spacing, landscaping, and building materials?
The building’s structure is currently planned to be built out of cast in place concrete and this will reduce the transfer of
sound vertically between the commercial spaces and residential units. Double stud demising walls will help with
horizontal noise movement between units on upper levels. Exterior walls on the east and west will be built out of
CMU and will greatly reduce any noise impacts between buildings.
9. If a lighting plan is provided, how does it augment security, energy conservation, safety, and aesthetics?
The lighting plan aims to provide safe and comfortable lighting levels along the alley and along Pearl Street.
Specialty lighting has been added to the window openings on Pearl Street to add a unique and beautiful addition to
the East Pearl neighborhood. Motion activated lighting fixtures are proposed where appropriate to conserve energy
and provide safety in that area.
Agenda Item 5A Page 25 of 360
www.theSTUDIOarchitecture.com - 1350 Pine Street | Suite 1 | Boulder | CO | 80302 - 866 | 529 | 9130
10. How does the project incorporate the natural environment into the design and avoid, minimize, or mitigate
impacts to natural systems?
The property is not in a natural environment.
11. How are cut and fill minimized on the site, and how does the design of buildings conform to the natural contours
of the land, and how does the site design minimize erosion, slope instability, landslide, mudflow or subsidence, and
minimize the potential threat to property caused by geological hazards?
This is an urban site so there aren’t any slopes or geological hazards.
(G) Solar Siting and Construction: For the purpose of insuring the maximum potential for utilization of solar energy
in the city, all applicants for residential site reviews shall place streets, lots, open spaces, and buildings so as to
maximize the potential for the use of solar energy in accordance with the following solar siting criteria:
1. Placement of Open Space and Streets. Open space areas are located wherever practical to protect buildings from
shading by other buildings within the development or from buildings on adjacent properties. Topography and other
natural features and constraints may justify deviations from this criterion. How is this criterion met?
This is a previously developed site so our proposal includes an infill building that meets the intent of the zone and
BVCP.
2. Lot Layout and Building Siting. Lots are oriented and buildings are sited in a way which maximizes the solar
potential of each principal building. Lots are designed to facilitate siting a structure which is unshaded by other
nearby structures. Wherever practical, buildings are sited close to the north lot line to increase yard space to the
south for better owner control of shading. How is this criterion met?
The building has been designed with an open court in the center to allow greater access to light and air for the
residences above. The property does not allow for increased yard space to the south since it is adjacent to Pearl
Street.
3. Building Form. The shapes of buildings are designed to maximize utilization of solar energy. Buildings shall meet
the solar access protection and solar siting requirements of Chapter 9-9- 17, "Solar Access," B.R.C. 1981. How is
this criterion met?
See the solar study in our proposal. We have set the proposed building back from the alley 15’ to allow the properties
to the north better solar access.
4. Landscaping. The shading effects of proposed landscaping on adjacent buildings are minimized. How is this
criterion met?
The proposed landscaping occurs within the court and along the alley, so shading on adjacent buildings will be
minimized. All trees proposed are deciduous trees that will provide beneficial shade in the summer and allow for
more solar access in the winter.
(H) Additional Criteria for Poles above the Permitted Height. No site review application for a pole above the
permitted height will be approved unless the approving agency finds all of the following:
1. The light pole is required for nighttime recreation activities, which are compatible with the surrounding
neighborhood, or the light or traffic signal pole is required for safety, or the electrical utility pole is required to serve
the needs of the city?; and
Not Applicable

REVISED 03/30/2020 (See underlined text)
LUR2018-00073
RE: 1737 Pearl – Parking Management Plan
This parking management plan is in response to City Staff comments regarding the proposed auto
elevator for the 1737 Pearl Street project.
I. Staff has concerns that the location and operations of the auto elevator will require waiting
vehicles to queue into the alley right-of-way and obstruct vehicle circulation within the alley
Response: This proposal has provided for a generous delivery/auto queueing area adjacent to
the elevator entry and off of the alley that will allow vehicles to wait for the elevator in the event
that it is occupied. This will be communicated to the apartment renters in their leasing package
and to the condo owners in their operations manual. Deliveries for the Retail spaces will be
scheduled for off-peak hours to minimize the chances that the waiting area will be occupied by a
delivery truck. In the event that a delivery truck is occupying the waiting area and the elevator is
in use, the waiting vehicle will have to pause in the alley until the waiting area is vacant or the
elevator is ready for use. The alley does has a 20’ right-of-way which would allow other vehicles to
safely pass the waiting vehicle.
II. Maintenance and repair plan
Response: The Ownership group intends to execute a service contract with the auto elevator
manufacturer, which will include urgent service calls. Maintenance for the elevator will be
performed at the required intervals per the elevator manufacturer. The property Owner’s
Association will oversee the maintenance of the auto elevator and the cost. MEI elevator has an
elevator repair service facility on E 42nd Ave in Denver, so response time for maintenance and
repairs will be minimized.
III. How will funds be set aside or collected for the maintenance and repair of the auto elevator
Response: The cost of the auto elevator’s maintenance service contract will be allocated to the
residential units on a pro-rata basis as part of their Owner’s Association dues. Additionally, the
Owner’s Association will develop and implement a small annual budget for a ride share service in
the event the auto elevator is out of service during times that restrict residents from using their
vehicles.
IV. How will vehicles that can’t be accommodated by the elevator and where those vehicles will
park on the site
Response: The elevator will be the size of a typical Boulder parking space (9’x19’) and will be able
to accommodate vehicles up to 98” in height (per ADA standards for accessible van height). This
system will be able to accommodate the same vehicles that could be accommodated with a
typical “ramp accessed” parking garage.
V. Detail the necessary supporting equipment or cabinets and where the supporting equipment
will be located on site
Response: A detailed specification for Holeless Freight Elevators has been included with this
resubmittal. Refer to the specification for detailed information. An elevator machine room
(EMR) has been provided in the parking garage level, directly adjacent to the elevator which will
house the required mechanical equipment. An emergency backup generator will be provided on
the roof to support the elevator functions in an emergency.

Transportation Demand Management Plan for 1737 Pearl Street
12/3/2018
REVISED 07/08/2019
REVISED 09/30/2019
REVISED 11/11/2019
Introduction
1737 Pearl Street is a 14,111 SF property on the north side of Pearl Street near the corner of 18th Street and is within
the CAGID boundary. The proposal for the site includes a new thee-story, mixed-use building with a total of 10
residential units on the second floor, 4 units on the third floor and retail, retail service and access to the below grade
parking on the ground floor. A loading space and access to the trash room are also provided at grade off of the alley.
This proposal includes adding short-term bicycle parking to the existing short-term bicycle parking on the NW corner
of Pearl St. and 18th as well as some short-term bicycle parking to the Pearl Street ROW directly adjacent to the
subject property. The alley will see improved paving and the addition of trees, planters, and lighting. Also, the
existing overhead utility lines in the alley will be undergrounded.
Existing Transit Service
Figure 1, indicates the existing transit routes and bus stops adjacent to or in the vicinity of the site. The site is 0.4
miles (8 min. walk) from the Downtown Boulder Bust Transit Station which provides a wide variety of regional bus
service including routes to Denver, DIA and elsewhere.
Being located in Downtown Boulder, the property also has great access to demand responsive services such as
peer-to-peer ridesharing, ride service hailing, food delivery, and bicycle sharing systems (Uber, Lyft, etc.).
Existing Bicycle and Pedestrian Network
Figure 2 shows the bike routes and pedestrian amenities in the vicinity of the site. The city of Boulder maintains an
extensive bicycle and pedestrian network throughout the city.
Transportation Demand Management (TDM) Strategy for Commercial and Residential uses
Table 1 shows the City of Boulder’s draft commercial development toolkit packages. The “core elements” section of
the table shows elements required of all new commercial developments, including:
· meeting the short- and long-term bicycle parking code
· participation in eGo car share and B-Cycle bike share where appropriate
· pedestrian and bicycle enhancements
· consideration of showers and changing facilities
· establishing a transportation information center.
One toolkit option is available under City of Boulder standards for the CAGID area: Package A. Package A requires
participation in the BECO bus pass program for employees and management of off-street parking if appropriate.
Table 2 shows the actions that the 1737 Pearl developer intends to implement to increase the percentage of
alternative travel modes.

Re: 1737 Pearl Street
Parking Garage Elevator
Queue Analysis
Boulder, CO
LSC #190210
Dear Mr. Wertz:
In response to your request, LSC Transportation Consultants, Inc. has prepared this Parking
Garage Entrance Queue Analysis for the proposed 1737 Pearl Street redevelopment in Boulder,
Colorado.
IMPACT AREA
Figure 1 shows the vicinity map. Figure 2 shows the conceptual site plan which includes the
location of the proposed parking garage elevator and the adjacent 20-foot public alley.
PROPOSED LAND USE AND ACCESS
The site is proposed to include 14 multi-family dwelling units above first floor retail space. The
10 residential units on the second floor will be for rent and the four residential units on the
third floor will be for sale. Full movement residential access is proposed to the alley north of
the site. The parking structure will be located under the building and will be accessed by a
vertical lift vehicle elevator. There is approximately 15 feet between the elevator door and the
south edge of the 20-foot public alley. The retail space is not required to provide parking spaces
because the site is located in the Central Area General Improvement District (CAGID). Retail
trips will likely be oriented to/from area parking garages or on-street parking. The conceptual
site plan is shown in Figure 2.
ALTERNATIVE TRAVEL MODES
An alternate travel mode share of 20 percent is expected based on the creation of a Travel De-
mand Management (TDM) plan. There are existing bus stops on Pearl Street near the inter-
section with 18th Street. There are existing sidewalks on both sides of Pearl Street, 17th Street,
and 18th Street. The 15th & Pearl Public Parking Garage is located about two blocks west of the
site.

1737 Pearl Street Parking Garage Elevator Queue Analysis
TRIP GENERATION
Table 1 from the July 30, 2019 Trip Generation and Assignment Report by LSC shows the esti-
mated typical weekday, morning peak-hour, and afternoon peak-hour trip generation for the
site based on the rates from Trip Generation, 10th Edition, 2017, by the Institute of Trans-
portation Engineers (ITE).
The residential portion of the site is expected to generate about 103 one-way vehicle-trips on
the average weekday, with about half entering and half exiting the site during a 24-hour period.
During the morning peak-hour, which generally occurs for one hour between 6:30 and 8:30
a.m., about 2 vehicles would enter the garage and about 5 vehicles would exit the garage.
During the afternoon peak-hour, which generally occurs for one hour between 4:00 and 6:30
p.m., about 5 vehicles would enter the garage and about 3 vehicles would exit the garage.
These volumes are expected to be reduced by about 20 percent due to alternative travel modes
based on the creation of a Travel Demand Management (TDM) plan. The net trip generation
potential after the TDM reduction is two vehicles entering and four vehicles exiting the garage
during the morning peak-hour and four vehicles entering and three vehicles exiting the garage
during the afternoon peak-hour.
SERVICE RATE FOR VEHICLE ELEVATOR
The elevator manufacturer indicates a typical range of 24 to 27 seconds for the garage door to
open and close, move to the other level, and then open and close and return to the original
level. This range excludes driver perception/reaction time and the time it takes to pull in and
out of the elevator. A very conservative service rate of 60 seconds per vehicle was used in the
queuing analysis.
ARRIVAL RATE FOR VEHICLES
The trip generation section above shows two entering vehicles are expected to arrive at the
elevator in the morning peak-hour and four entering vehicles are expected to arrive at the ele-
vator in the afternoon peak-hour.
QUEUING ANALYSIS
The average queue lengths were estimated using a typical M/M/C Queuing Model which esti-
mates queuing based on the vehicle arrival rate compared to the vehicle service rate.
The probability of no entering vehicles being served at any given time in the afternoon peak-
hour is 93.34 percent.
The probability of one entering vehicle being served at any given time in the afternoon peak-
hour is 6.22 percent.
The probability of two entering vehicles being served at any given time in the afternoon peak-
hour is 0.41 percent.

Dear Mr. Wartz:
In response to your request, LSC Transportation Consultants, Inc. has prepared this Trip Gene-
ration and Assignment Report for the proposed 1737 Pearl Street redevelopment in Boulder,
Colorado.
IMPACT AREA
Figure 1 shows the vicinity map.
Area Roadways
The major roadways in the site’s vicinity are shown on Figure 1 and are described below.
• Pearl Street is an east-west, two-lane minor arterial roadway south of the site. The inter-
section with 17th Street is signalized and the intersection with 18th Street is unsignalized.
The posted speed limit in the vicinity of 17th Street is 20 mph with a transition to 30 mph
to the east. There are detached sidewalks on both sides of the roadway. There are bus
stops near the intersection with 18th Street.
•17th Street is a north-south, two-lane collector roadway west of the site. The intersection
with Pearl Street is signalized. No speed limit is posted in the vicinity of the site. There are
sidewalks and on-street parking on both sides of the roadway.
•18th Street is a north-south, two-lane local roadway east of the site. The intersection with
Pearl Street is unsignalized. No speed limit is posted in the vicinity of the site. There are
detached sidewalks and on-street parking on both sides of the roadway.
PROPOSED LAND USE AND ACCESS
The site is proposed to include about 14 multi-family dwelling units and about 7,677 square
feet of restaurant space. The 10 units on the second floor will be for rent and the four units on
Agenda Item 5A Page 72 of 360
Mr. Adam Wartz Page 2 July 30, 2019
1737 Pearl Street
the third floor will be for sale. Full movement residential access is proposed to the alley north
of the site. The restaurant space is not required to provide parking spaces because the site is
located in the Central Area General Improvement District (CAGID). Restaurant trips will likely
be oriented to/from area parking garages or on-street parking. The conceptual site plan is
shown in Figure 2.
ALTERNATIVE TRAVEL MODES
An alternate travel mode share of 20 percent is expected. There are existing bus stops on Pearl
Street near the intersection with 18th Street. There are existing sidewalks on both sides of Pearl
Street, 17th Street, and 18th Street. The 15th & Pearl Public Parking Garage is located about two
blocks west of the site.
TRIP GENERATION
Table 1 shows the estimated typical weekday, morning peak-hour, and afternoon peak-hour
trip generation for the site based on the rates from Trip Generation, 10th Edition, 2017, by the
Institute of Transportation Engineers (ITE).
The site is projected to generate about 964 one-way vehicle-trips on the average weekday, with
about half entering and half exiting the site during a 24-hour period. During the morning peak-
hour, which generally occurs for one hour between 6:30 and 8:30 a.m., about 44 vehicles would
enter and about 39 vehicles would exit the site. During the afternoon peak-hour, which
generally occurs for one hour between 4:00 and 6:30 p.m., about 52 vehicles would enter and
about 32 vehicles would exit the site. These volumes are expected to be reduced by about 20
percent due to alternative travel modes.
TRIP DISTRIBUTION
Figure 3 shows the estimated distribution of residential site-generated traffic. The restaurant
space is not required to provide parking spaces because the site is located in the Central Area
General Improvement District (CAGID). Restaurant trips will likely be oriented to/from area
parking garages or on-street parking.
TRIP ASSIGNMENT
Figure 4 shows the assignment of residential site-generated traffic assuming no reduction for
alternative travel modes to assure a conservative analysis.
OVERALL TRAFFIC IMPACTS
The project is expected to generate less than ten new residential trips during either peak-hour
and the restaurant trips will be disbursed among the various public parking alternatives in the
area. A traffic study should not be needed as the residential trip generation potential will be
relatively low and the restaurant trips will be well disbursed.

1.0 INTRODUCTION
This Preliminary Drainage Report [Report] is prepared on behalf of BW Sons & Daughters LLC for
the proposed NAVY 1727 and 1737 Pearl Street Redevelopment project. The purpose of this
report is to address the City of Boulder’s [City] requirements for a “Preliminary Storm Water Report
and Plan” as outlined in Chapter 7 “Storm Water Design”, “Design and Construction Standards” [1].
This Report documents the existing drainage conditions present at the site and provides an analysis
of the drainage conditions proposed for the NAVY 1727 and 1737 Pearl Street Redevelopment
project.
2.0 EXISTING SITE CONDITIONS
The proposed NAVY 1727 and 1737 Pearl Street Redevelopment project site is located on the
north side of Pearl Street between 17st Street and 18th Street. The site is in the Southwest quarter of
Section 30, Township 1 North, Range 70 West of the 6th P.M., County of Boulder, City of Boulder, State
of Colorado.
The 14,111-sf (0.324 acre) project site consists of two adjacent parcels and measures approximately
100-ft wide by 140-ft deep. The legal description is:
Lots 10 and 11, Block 91, Boulder Old Town East, County of Boulder, State of Colorado.
The adjacent lots are developed commercial properties.
As shown on the “Existing Conditions Drainage Plan” included in the back pocket of this report, the
existing 1727 Pearl Street parcel is currently developed with a multi-story commercial building and
associated private gravel parking/loading area on the north side of the building. The 1737 Pearl
Street parcel is currently developed with a single-story commercial building and associated private
asphalt parking/loading area on the north side of the building. There is a 20-ft wide alley that lies
immediately to the north of the project site.
USDA Natural Resources Conservation Services classified the soils on the property as Niwot Soils
(Nh) having a Group B hydrologic soil [2].

The Sanitas Group, LLC 801 Main Street, Suite 225 I Louisville, CO 80027 720.346.1656
The property is shown as being outside the 100-year floodplain for Boulder Creek. The 500-year
floodplain does impact the site. There are no 500-year floodplain regulations that impact the
proposed development as no Critical Facilities are proposed.
3.0 PROPOSED DEVELOPEMENT
The proposed NAVY 1727 and 1737 Pearl Street Redevelopment project will include the
demolition of all existing site improvements and the construction of a three-story mixed-use building
with ground level commercial space and 14 residential units on the upper levels. Vehicular access to
the site will be from the existing alley to the north. A vehicle elevator will be located on the north
side of the building that will lower cars to an underground parking garage located in the basement
level of the proposed building. The section of the alley adjacent to the project site as well as the alley
section east to the intersection with 18th Street will be reconstructed and repaved with concrete. The
proposed development will maintain historic drainage patterns with flows being directed to the
southeast. The proposed development layout and grading is shown on the “Proposed Conditions
Drainage Plan” included in the back pocket of this report.
4.0 DESIGN CRITERIA
This Report was prepared using the criteria outlined in the City of Boulder “Design and Construction
Standards”, Chapter 7 “Storm Water Design” [Criteria] [1], the Urban Drainage and Flood Control
District [UDFCD] “Urban Storm Drainage Criteria Manual, Volumes 1 and 2” [4], and the Urban
Drainage and Flood Control District “Urban Storm Drainage Criteria Manual, Volume 3 – Best
Management Practices” [5].
5.0 HYDROLOGY
The rational method was used to calculate runoff rates for the 2-year, 5-year, 10-year and 100-year
storm events. The proposed project is a mixed-use commercial/residential development and the 5-
year and 100-year events are presented as the minor and major design storms, respectively.
Existing Conditions
The existing drainage basins are delineated on the “Existing Conditions Drainage Plan” provided in
the back pocket of this report. Drainage basin delineation, storm flow directions and off-site drainage
conditions were determined visually during a site visit in November 2018. The property is not

The Sanitas Group, LLC 801 Main Street, Suite 225 I Louisville, CO 80027 720.346.1656
subject to any observable significant offsite tributary drainage. The property to the east is located
downstream of the site. The property to the west drains to the northeast and into the existing alley.
The project site will be designed to maintain these flow patterns.
The existing site has been delineated into two primary existing drainage basins. Basin Ax consists of
the existing west building and the asphalt and gravel parking areas located on the north side of the
existing buildings. Also included in Basin Ax are three concrete areas located on the north side of the
buildings. The roof drains to the north to downspouts that discharge to the surface on the north side
of the building. Runoff on the asphalt and gravel areas sheet flows to the north to the alley. The alley
slopes downward to the east towards 18th Street which slopes to the south to Pearl Street. From the
intersection of 18th Street and Pearl Street runoff flows east in Pearl Street to 21st Street where runoff
is intercepted by the City’s storm sewer system.
Basin Bx consists of the existing east building. The existing roof slopes to the south. The roof
drainage is piped to a sidewalk chase drain located in the Pearl Street sidewalk near the southeast
corner of the existing building which conveys the roof drainage to the street. Pearl Street drains to
the east as described above.
Existing conditions storm water runoff is presented in Table 5.1. Basin description, imperviousness,
weighted runoff coefficients, time of concentration and runoff values are provided for the existing
drainage basin on a worksheet labeled “Rational Method Calculations” provided in Appendix A. For
ease of reference, the existing conditions storm water flows are presented on the “Existing Conditions
Drainage Plan” provided in the back pocket of this report.

Proposed Conditions
The proposed on-site drainage basins are delineated on the “Proposed Conditions Drainage Plan”
provided in the back pocket of this report. With the development proposal, the site is divided into
five primary drainage basins, Basins A1 through A4, B1 and B2. Basin A1 consists of the westerly
approximately 3/4 of the proposed building, with the exception of the courtyard area in the center
of the building. The roof drainage from Basin A1 will be piped to one of two rain gardens that will be
located on the north side of the building adjacent to the alley. Proposed permanent water quality
measures for the site are discussed in Section 7.0 below.
Basin A2 consists of the easterly approximately 1/4 of the proposed building. The roof drainage from
Basin A2 will be piped to the second rain garden that will be located on the north side of the building
adjacent to the alley.
Basin A3 covers the main loading and parking garage access drive area on the north side of the
building. This basin consists of concrete sloping towards the alley for 10-feet from the building wall
with a proposed 4-foot wide permeable paver band located adjacent to the alley to provide water
quality treatment to runoff from the adjacent concrete. See Section 7.0 for additional discussion
regarding the proposed permeable pavers.
Basin A4 consists of the remaining concrete and utility (transformers, etc.) on the north side of the
structure that discharge directly to the alley in a historic manner as it is not feasible to release to a
raingarden or permeable paver feature.
Basin B1 covers the small central open courtyard area, consisting of concrete patio and a landscape
planter. Runoff from Basin B1 will sheet flow to a trench drain system that will drain to the south
through the courtyard access walkway and into the relocated sidewalk chase drain in the Pearl Street
sidewalk. The existing sidewalk chase drain in Pearl Street will be removed and reconstructed
approximately 30 feet west of the existing location to convey the courtyard drainage to Pearl Street,
following historic drainage patterns. While the City of Boulder desires to eliminate sidewalk chase
drains wherever possible, the lack of storm sewer in the proximity of the project site prevents the
installation of standard drains and storm pipe to drain the proposed open courtyard, therefore the
project proposes to maintain a chase drain in this area. The proposed site layout will significantly

reduce the amount of area and flow discharging to the sidewalk chase, with a proposed
redevelopment discharge of 0.19 CFS and 0.38 CFS for the minor and major storm events,
respectively.
Basin B2 consists of the small areas of concrete along the south side of the proposed building. Runoff
from Basin B2 will sheet flow south into Pearl Street.
Proposed conditions storm water runoff for each basin is presented in Table 5.2. Basin description,
imperviousness, weighted runoff coefficients, time of concentration and runoff values are provided
for the proposed drainage basin on a worksheet labeled “Rational Method Calculations” provided in
Appendix B. For ease of reference, the proposed conditions storm water flows are presented on the
“Proposed Conditions Drainage Plan” provided in the back pocket of this report. A comparison of
Existing and Proposed Conditions runoff rates for the site discharge points is presented in Table 5.3.

The proposed conditions runoff rates entering the alley at Design Point 1 will decrease during the
minor storm and increase during the major storm. The runoff rates to Pearl Street at Design Point 2
will decrease for both the minor and major design storms.
6.0 STORM WATER DETENTION
The proposed redevelopment of the project site will increase the overall impervious area as well as
the expected peak runoff rates for both the minor and major storm events. Stormwater detention
volume will be provided in the two proposed rain gardens on the north side to store the increased
runoff from the site and release the runoff at the historic rate in accordance with Section 7.12 in the
Criteria. A storage volume equal to 110% of the difference between the historic and proposed
conditions runoff will be provided above the water quality capture volume (WQCV). Both the minor
and major storm runoff rates will be controlled by a weir opening on the north side of the rain
gardens where runoff will drain towards the alley, following historic drainage patterns. Due to the
lack of storm sewer in the area and proximity to the foundation, the raingarden features need to be
elevated. Therefore, portions of the area on the north side of the building cannot drain into the
raingardens and therefore will be free released. In order to limit impacts, a band of permeable pavers
is being provided between the primary loading/access area and the alley. These permeable pavers
will provide water quality and reduce runoff from the adjacent concrete. To be conservative in the
runoff analysis, for detention design purposes the permeable pavers are not included in the detention
analysis and are assumed to be at capacity or plugged, with the raingarden release rates adjusted to
control overall site releases to historic levels. See Section 7.0 for additional discussion regarding the
permeable pavers.
The internal courtyard will free release towards Pearl Street based on discussions with City staff as
due to the lack of storm sewer in the area it is not practicable to provide detention or formal water
quality for this area. The anticipated discharge rates from this area are minimal (less than 0.2 CFS
for the minor storm) and there are limited sources for pollutants in this area. Per discussions with
staff, the existing sidewalk chase drain will be relocated west to align with the courtyard access to
provide an outlet from runoff from the courtyard.

The section of the alley adjacent to the project site and out east to 18th Street will be reconstructed
with a concrete alley section to improve the conveyance capacity of the alley.
7.0 STORMWATER QUALITY AND EROSION CONTROL
The proposed project will increase the overall impervious area and runoff coefficients for the site;
therefore, the project is required to provide permanent water quality treatment. With existing and
proposed conditions impervious areas of 78% and 87%, respectively, the site is designed to meet the
Stormwater Quality Design Standard, Constrained WQCV Standard described in Section
7.15(C)(1)(d)(ii) in the Criteria. The Constrained WQCV Standard requires treatment and/or
infiltration of the runoff from at least 50% of the treatment area, including at least 50% of the
impervious area, for the 80th percentile, 0.6-inch storm event. The site proposes two raingarden
features as well as a band of permeable pavers on the north side of the site to treat as much of the
site runoff as possible. The proposed permanent water quality features are designed to provide
treatment of the runoff for approximately 82% of the site. Recessing the raingardens into grade to
allow the adjacent concrete areas to utilize them is not feasible as storm sewer is not present in the
project vicinity and full infiltration of the raingarden is not feasible due to proximity to the building
foundation and geotechnical requirements. The raingarden WQCV is designed to drain in 12 hours
via orifices per UDFCD.
The remaining portion of the north side of the site between the building and alley not covered by
raingarden consists primarily of concrete and utilities. The areas on the east and west end are
constrained by utility (electric and gas) facilities as well as egress requirements, therefore these
areas (totaling approximately 0.013 -Acres) will free release to the alley. A small landscape area has
been included on the east side of the loading area for a tree and to collect initial raingarden discharge.
The westerly rain garden area was adjusted to account for a tree to be planted in the rain garden.
Due to the small size of the rain garden, the largest anticipated tree diameter is 12-inches, therefore
the westerly rain garden area was reduced by 1-s.f. The central portion of concrete serving as the
access to the parking garage as well as for deliveries, etc. will have a permeable paver band installed
to provide water quality since this area will see frequent vehicular movements. The permeable paver
system will be based on a full infiltration design due to the lack of storm sewer outfall. While full
infiltration of the raingardens was not possible, the anticipated small discharge rate from Basin A3
into the pavers (0.04 CFS for the 2-year storm and 0.14 CFS for the 100-year) and the fact that the
Agenda Item 5A Page 88 of 360

The Sanitas Group, LLC 801 Main Street, Suite 225 I Louisville, CO 80027 720.346.1656
pavers can be placed 10-feet from the foundation; we feel the permeable pavers in this area will
provide some water quality and runoff impact benefit while not creating a groundwater impact on
the proposed structure or adjacent structures. The project geotechnical report indicates a 10-12-
foot layer of slightly clayey sand and gravel on the site. Formal infiltration testing of the existing
conditions is still to be performed but utilizing guidelines for septic system design in the area the
sandy-gravel soils identified by the project geotechnical engineer would typically require a Long-
Term Acceptance Rate (LTAR) of 0.8-1.0 in/hr for design purposes. Septic LTAR design rates are
typically lower than field infiltration testing rates, but lacking field testing at this time we are utilizing
the lower septic design rate of 0.8 in/hr. Applied over the 220 S.F. paver footprint results in a
preliminary infiltration capacity of 14.67 C.F. per hour or 176 C.F. per 12-Hour WQ drain period. The
required WQCV for the paver system is 12 C.F and the provided volume is 37 C.F. Applying the
recommended 2x safety factor, the preliminary design is still below the 12-hr drain capacity of the
system.
Construction Best Management Practices [BMPs] will be installed prior to and during construction,
to restrict the amount of sediment transported offsite by either wind or water. Construction BMPs
include vehicle tracking control at the construction entrance, silt fencing, concrete washouts and dust
control. Detailed construction stormwater management plans will be provided at the time of
Technical Document Review as necessary.
8.0 WETLAND IMPACTS
There are no known wetlands located on the project site.
9.0 CONCLUSIONS
This Report meets the City’s requirements for Preliminary Drainage Report information as outlined
in the Criteria. The Report documents the existing drainage conditions present at the site and
provides an analysis of the drainage conditions and water quality measures proposed for the NAVY

Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil

Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.

Description
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive
precipitation from long-duration storms.
The soils in the United States are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when
thoroughly wet. These consist mainly of deep, well drained to excessively
drained sands or gravelly sands. These soils have a high rate of water
transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well
drained soils that have moderately fine texture to moderately coarse texture.
These soils have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of
water transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink-swell
potential, soils that have a high water table, soils that have a claypan or clay
layer at or near the surface, and soils that are shallow over nearly impervious
material. These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in
their natural condition are in group D are assigned to dual classes.

About MEI
Since 1971, MEI has specialized in the manufacture, installation, modernization,
and servicing of various types of elevators. Our manufactured equipment is
found in every US state as well as several foreign countries. In addition, we
install, modernize, and service equipment within the Midwest.
MEI is a licensed, insured, and bonded elevator contractor and a member of
the National Association of Elevator Contractors. Our equipment meets the
requirements of the ASME A17.1 code / CSA B44.
Customer Focus
We provide several packages for standard applications, however, we specialize in
adapting our product to customer requirements. Each elevator produced by MEI
is individually engineered. This process allows us to customize each application
without costly fees or extensive lead times. Examples of our work include
passenger cars with front and side openings, elevators with unusual platform
shapes, automobile lifts, 40,000# capacity freight cars, and 80,000# capacity semi
truck lifts.
Currently, MEI manufactures about 500 elevators annually at their Mankato, MN
headquarters location. A variety of passenger, freight, and service applications
are built and shipped to locations in both the public and private sectors. Job
sites include churches, schools, convention centers, hotel complexes, airport
expansions, transit stations, stadiums, hospitals, industrial plants, and shopping
centers. Many of our customers are independent contractors, but we also
provide equipment to major elevator companies.
Installation Experience
MEI installs approximately 100 cars per year within the Midwest. Since we
receive direct feedback from the mechanics working with our equipment, we are
able to continually fine-tune our designs for easier installation. MEI engineers
also visit various jobsites for valuable hands-on experience. Our expertise in this
area results in dependable, practical equipment and smooth installation.
At MEI, we pride ourselves on delivering expert engineering, quality equipment,
and excellent customer service.
We look forward to hearing from you.MEI Story

In-Ground, Rear/Side SlungPassenger
Agenda Item 5A Page 191 of 360
Application Summary
This design utilizes two hydraulic jacks and provides
maximum structural stability. The jacks, located
on each side of the car, are either single-stage or
telescopic. The appropriate jack type is determined
by the amount of travel and the project conditions.
The single-stage jacks are popular for two-stop
arrangements, while telescopic jacks are generally
used for three- and four-stop projects.
Advantages
• No jack hole is required. This eliminates the
cost of drilling and the risk of oil contamination.
• Accommodates front and rear openings in any
configuration.
• Available for both low and high capacity cars.

Pit Depth = 4’-0” • Minimum Overhead (See Below) , * Denotes Minimum Overhead = 12’-5” • Cab Height = 8’-0”
Guidelines for determining overhead required:
For 1 Stage Jack
A) Car Speed = Up to 150 FPM
B) Top Overtravel = 5”
C) Bottom Overtravel = 12”
D) Pit Depth = 4’-0”
E) Cab Height = 8’-0”
For 2 Stage Jack
A) Car Speed = Up to 150 FPM
B) Top Overtravel = 12”
C) Bottom Overtravel = 10”
D) Pit Depth = 4’-0”
E) Cab Height = 8’-0”
One Stage Jack Overhead Requirement:
Minimum of 12’-0” overhead required for 12’-0” of travel and under. If over
12’-0” travel, overhead must equal or be greater than total travel.
Two Stage Jack Overhead Requirement:
Minimum of 12’-8” overhead required for 20’ of travel and under. Add 1⁄2”
to 12’-8” for every additional 1” of travel over 20’-0”.

Application Summary
This is a holeless design limited to low capacity
applications. Wire ropes are utilized in conjunction with
a hydraulic jack to lift the car at a 1:2 ratio. For every foot
that the jack rises, the car rises two feet. The jack and rail
equipment is mounted either to the side or to the rear of
the car, depending upon the opening configuration.
Advantages
• No jack hole is required and with that there is no risk
of oil contamination in the ground.
• Front & side openings can be easily accommodated.
• No extensive pit or overhead is required.

Cantilever Roped, Rear/Side SlungPassenger
Agenda Item 5A Page 196 of 360
Application Summary
This design utilizes a gearless machine, ropes, and
counterweights instead of hydraulic equipment. The main
guide rails are mounted on each side of the car and an
additional pair of counterweight rails is located on one
side. The gearless machine, along with the related drive
equipment is all installed inside the hoistway eliminating the
need for a machine room saving you valuable floor space.
Advantages
• Requires a smaller control room rather than a full
size machine room
• Reduces height of rooftop projection versus Traction
applications
• Shorter minimum overhead than Rail Mounted MRL
application
• Advantages over hydraulic applications:
• Lower power requirements
• Greater energy efficiency
• Allows significantly higher car speeds

Agenda Item 5A Page 198 of 360
Note: Visit our website for downloadable elevation and plan view drawings.
Application Summary
This design utilizes a geared machine, ropes, and
counterweights instead of hydraulic equipment. The
main guide rails are mounted on each side of the car and
an additional pair of counterweight rails is located on one
side or at the rear. The geared machine, along with the
related drive equipment, is generally located above the
hoistway in a penthouse machine room. In some limited
situations, it can be located next to the hoistway at a
lower landing. This latter arrangement is referred to as a
basement traction.
Advantages
• No risk of oil contamination to the ground.
• Accommodates front and rear openings in any
configuration.
• Available for both low and high capacity cars.
• Nearly unlimited floor travel is possible.
• Has greater power efficiency than hydraulic
applications.
• Allows significantly higher car speeds than hydraulic
designs.OCA

Based on car speed of 200 fpm • Cab Height = 8’-0” • For seismic applications add 3” to hoistway width and 1” to hoistway depth
* Speeds exceeding 200 FPM require additional overhead and pit depth.
Minimum pit depth is based on the use of spring buffers. Add 5” to pit
depth if oil buffers are required or car speed exceeds 200 FPM.
225 FPM = add 6” of overhead & 5” of pit depth
250 FPM = add 7” of overhead & 5” of pit depth
300 FPM = add 8” of overhead & 5” of pit depth
350 FPM = add 10” of overhead & 5” of pit depth

C l a s s u p your Cab
If you are looking for an upscale cab design, MEI offers many options
for custom cab interiors. Options vary from cost effective laminate that
upgrade the look and feel of the cab to pre-fabricated cab interiors that
are installed into the cab shell at the end of the construction project
helping eliminate damages that can occur during the construction
phase. Many materials can be used together for a great look...glass,
wood, bronze, etc. There are many interior feature options from cab
walls, ceilings, handrails and more. We will work with you to review all
of your options and here are a few to get you started.

Application Summary
This design utilizes two hydraulic jacks and provides
maximum structural stability. The jacks, located on each
side of the car, are either single-stage or telescopic. The
appropriate jack type is determined by the amount of
travel and the project conditions. The single-stage jacks
are popular for two-stop arrangements, while telescopic
jacks are generally used for three- and four-stop projects.
Advantages
• No jack hole is required. This eliminates the cost of
drilling and the risk of oil contamination.
• Accommodates front and rear openings in any
configuration.
• Available for both low and high capacity cars.
Guidelines for determining overhead required: Overhead Requirements:
For 1 Stage Jack
A) Car Speed = Up to 150 FPM
B) Top Overtravel = 5”
C) Bottom Overtravel = 12”
D) Pit Depth = 4’-6”
E) Cab Height = 8’-0”
For 2 Stage Jack
A) Car Speed = Up to 150 FPM
B) Top Overtravel = 12”
C) Bottom Overtravel = 10”
D) Pit Depth = 4’-6”
E) Cab Height = 8’-0”
One Stage Jack with Single Section Gate:
Minimum of 14’-6” overhead required for 14’-6” of travel and under. If over
14’-6” travel, overhead must equal or be greater than total travel.
One Stage Jack with Two Section Gate:
Minimum of 12’-4” overhead required for 12’-4” of travel and under. Add
1” to 12’-4” for every additional 1” of travel over 12’-4”.
Two Stage Jack with Single Section Gate:
Minimum of 15’-1” overhead required for 26’-8” of travel and under. Add
1⁄2” to 15’-1” for every additional 1” of travel over 26’-8”.
Two Stage Jack with Two Section Gate:
Minimum of 13’-0” overhead required for 22’-6” of travel and under. Add
1⁄2” to 13’-0” for every additional 1” of travel over 22’-6”.
Notes:
• Overhead dimensions are based on 6 foot high car gate.
• Two section car gates are not recommended for high usage installations or wide openings.
• For extra high door opening requirements, or special conditions, consult your representative.
• Standard Cab Height H = 8’-0”
Code year adoptions and local code
variations may affect the hoistway size.

Application Summary
This design utilizes two hydraulic jacks and provides
maximum structural stability. The telesopic jacks
are located on each side of the car.
Advantages
• No jack hole is required. This eliminates
the cost of drilling and the risk of oil
contamination.
• Accommodates front and rear openings in any
configuration.
• Available for both low and high capacity cars.
• Less overhead required than 2 stage holeless.
Guidelines for determining overhead required: Overhead Requirements:
For 3 Stage Jack
A) Car Speed = Up to 150 FPM
B) Top Overtravel = 12”
C) Bottom Overtravel = 8”
D) Pit Depth = 4’-6”
E) Cab Height = 8’-0”
3 Stage Jack with Single Section Gate:
Minimum of 15’-1” overhead required for 38’-9” of travel and under.
Add 11⁄32” for every additional 1” of travel over 38’-8”.
3 Stage Jack with Two Section Gate:
Minimum of 13’-0” overhead required for 32’-0” of travel and under.
Add 11⁄32” to 13’-0” for every additional 1” of travel over 32’-9”.
Notes:
• Overhead dimensions are based on 6 foot high car gate.
• Two section car gates are not recommended for high usage installations or wide openings.
• For extra high door opening requirements, or special conditions, consult your representative.
• Standard Cab Height H = 8’-0”Code year adoptions and local code
variations may affect the hoistway size.
Verify all dimensions with MEI prior to
construction.

Application Summary
This design utilizes wire ropes in conjunction with two
hydraulic jacks to lift the car at a 1:2 ratio. For every foot
that the jacks rise, the car rises two feet. The use of two
jacks, one on each side of the car, provides maximum
structural stability.
Advantages
• No jack hole is required and with that there is no risk
of oil contamination in the ground.
• Accommodates front and rear openings in any
configuration.
• No extensive pit or overhead is required.
• Large platform designs and high capacity projects can
be accommodated.
Notes:
• Overhead dimensions are based on 6 foot high car gate.
• Two section car gates are not recommended for high usage installations or wide openings.
• For extra high door opening requirements, or special conditions, consult your representative.
• Standard Cab Height H = 8’-0”
• Minimum Overhead for Single Section Gates: = 14’-6”
• Minimum Overhead for Two Section Gates: = 12’-4”
Code year adoptions and local code
variations may affect the hoistway size.
Verify all dimensions with MEI prior to
construction.

Application Summary
This design utilizes a geared machine, ropes, and
counterweights instead of hydraulic equipment.
The main guide rails are mounted on each side of
the car and an additional pair of counterweight
rails is located on one side or at the rear. The
geared machine, along with the related drive
equipment, is generally located above the hoistway
in a penthouse machine room. In some limited
situations, it can be located next to the hoistway at
a lower landing. This latter arrangement is referred
to as a basement traction.
Advantages
• No risk of oil contamination to the ground.
• Accommodates front and rear openings in any
configuration.
• Available for both low and high capacity cars.
• Nearly unlimited floor travel is possible.
• Has greater power efficiency than hydraulic
applications.
• Allows significantly higher car speeds than
hydraulic designs.
Notes:
• Overhead dimensions are based on 6 foot high car gate.
• Two section car gates are not recommended for high usage installations or wide openings.
• For extra high door opening requirements, or special conditions, consult your representative.
• Standard Cab Height H = 8’-0”
* Speeds exceeding 200 FPM require addional overhead and pit depth. Minimum pit depth is based on
the use of spring buffers. Add 5” to pit depth if oil buffers are required or car speed exceeds 200 FPM.
225 FPM = add 6” of overhead & 5” of pit depth
250 FPM = add 7” of overhead & 5” of pit depth
300 FPM = add 8” of overhead & 5” of pit depth
350 FPM = add 10” of overhead & 6” of pit depth
Code year adoptions and local code
variations may affect the hoistway size.
Verify all dimensions with MEI prior to
construction.

How it Works
The Oil Cooler can be mounted to the power unit or located in a remote location*. When the
oil temperature in the reservoir reaches a preset limit, it is circulated through the radiator.
This process reduces the oil temperature by nearly 40°F, depending on site conditions. The
oil is also filtered as it runs through the system, which results in enhanced performance and
extended component life. The filter head has a sight gauge to indicate when the filter needs
to be changed.
*Remote location must be within 110 feet horizontally or 55 feet vertically from the power
unit. Piping, wiring, and conduit to remote location are not included.
• MEI recommends our Cold Weather Kit when your heat exchanger is installed where the
temperature gets below 50°F.

Oil Cooler Replacement Parts
Agenda Item 5A Page 229 of 360
Extend the Life of your Hydraulic Elevator System!
The MEI Silencer is an in-line device that reduces the noise and vibration of any
hydraulic power unit (similar to the muffler on an automobile).
Reduced Pulsations = Reduced Noise, Leakage, and
Component Wear.
Pump pulsations cause vibrations. Transmitted by the piping throughout the system,
vibrations cause noise, leakage, and early component failure. When the MEI Silencer
stops the pulsations, it stops the source of the vibrations. This improves system
performance and reduces service calls, pleasing your client and improving your
reputation.
Benefits
• 40-60% reduction in system noise and vibration
• Extended component life
• Fewer leaks
• Lower long-term system maintenance costs
• Smoother system operation
How it Works
Hydraulic pulsations (noise) enter the silencer and go through three different noise
baffles or diffusers. After passing through these baffles, the pulsations then strike a
rubber tube, or bladder, charged with air to 35% to 50% of the hydraulic operating
pressure. Hit by a pulsation, the bladder deflects slightly, reducing the size of the
pulsation and therefore, the noise.
Recommended Applications
• Dry or submersible hydraulic power units for all hydraulic elevator car types.

Installation & Maintenance Tools
Agenda Item 5A Page 238 of 360
Adjustable Piston Stabilizer (2 Required Per Application)
Stabilize piston during a cylinder replacement
This versatile piston stabilizer is an essential tool for safe and efficient
cylinder replacements. Simply attach to the upper portion of the piston to
maintain a secure, accurately-aligned piston during retrieval of the car from
the overhead. This tool installs in less than 5 minutes!
During a cylinder replacement, the elevator is typically hoisted and secured
in the top of the hoistway. The old piston and cylinder are then removed
and the new piston is installed. To complete the procedure, the new piston
is run up and attached to the bottom of the car sling (located in the top of
the hoistway). The further the piston is extended out of the cylinder, the
more unstable it becomes.
MEI’s Adjustable Piston Stabilizer ensures the safe, secure, and plumb
travel of the piston to the bottom of the car and eliminates the potential
for seal damage caused by excess movement. Save time and money by
using this tool instead of building custom stabilizers at each job site! The
MEI Adjustable Piston Stabilizer will accommodate a wide range of field
situations. Contact MEI for capabilities and pricing.
Piston Stabilizers
Stabilize pistons while checking for damage prior to seal
replacement
This fully-adjustable piston stabilizer ensures a safe packing seal
replacement and eliminates the possibility of damaging the new
packing seal. This simple tool keeps the piston secure during the
entire seal replacement process.
When changing out a seal, it is necessary to check the entire
length of the piston for damage and make any repairs prior to
installing the new seal. This is typically done by running the piston
from the car top to the upper limit of its travel. The risk when
doing this is that the further the piston is extended out of the
cylinder, the more unstable it becomes. The excess movement
puts considerable pressure and wear on the packing seal, and
the piston could also potentially catch a bracket or hoistway
obstruction. Use the MEI Piston Stabilizer on your next seal
replacement for an easier, safer repair! Contact MEI for pricing
and availability.

Top of Hoistway Target Bracket
Align rails easily with this versatile bracket
Nothing is more reliable and accurate than dropping plumb
lines for rail alignment. This efficient bracket attaches easily to
the top of the hoistway wall or to the underside of the hoist
beam. Secure the music wire for rail alignment. Eliminate the
laborious, costly task of building wooden targets on each and
every project! Contact MEI for pricing and availability.
Pit Target and Plumb Line Tension Device
Secure music wire and apply tension easily with this versatile bracket
This plumb line tension device is designed to be used in
conjunction with the Top of Hoistway Bracket. Simply locate,
secure to the pit floor, and run the music wire through the hole
in the top of the bracket. Attach to a ratchet and apply tension
to the alignment wire. Eliminate the need to build custom,
cumbersome targets in the pit! Contact MEI for pricing and
availability.

Reflex 3.14 Leveling System
Agenda Item 5A Page 248 of 360
Founded in 1971, MEI was born of the dreams and aspirations of
John Romnes. What started as a one-man operation in a rented
farmhouse has now grown to a multi-million dollar company
with more than 200 employees.
Before starting MEI, John had nine-and-a-half years of industry
experience. He was the only full-time employee of MEI for the first
seven months. In the early ‘70s, with two full-time employees,
including John himself and a part-time employee, John began to
expand his business splitting MEI time between service, repair,
modernizing and installing elevators. MEI built and installed its
first freight elevator in 1973 and its first passenger elevator in
1975 in Mankato; both were new elevators, built from scratch.
From 1971 - 1981, MEI’s service base grew to 110 service
contracts, consisting of approximately 330 elevators serviced by
two technicians. “During the first decade of MEI, I feel we were
blessed in many ways and experienced God’s favor, which helped
lay the groundwork for our future success,” John said.
MEI experienced rapid growth in the ‘80s, adding more
employees, building more elevators, acquiring more service
contracts and constructing its first factory building. From 10
employees in 1981 the company grew to employing 59 workers
by 1990.
In 1989, as a result of the company’s growth, John purchased
Vertitron and renamed it to Vertitron Midwest.
From 1982 - 1991, MEI’s service base continued to grow to 409
contracts, more than 1,200 elevators and 8 service technicians.
In the ‘90s, MEI’s service department sold nearly 500 new service
contracts.
A major effort was made to start diversifying the company’s
customer base for National Sales and carve out MEI’s niche for
custom work.
MEI grew from 59 employees in the early ‘90s to 178 in 2001.
In 2001, MEI’s service base had grown to 765 contracts, 2,300
elevators and approximately 14 service technicians. After
experiencing hard times from 2004 - 2006, John turned to Rick
Lowenberg, a lead turnaround consultant. MEI was armed with
a new business plan and in 2007; MEI won the Turnaround of the
Year Award from the Upper Midwest chapter of the Turnaround
Management Association and Rick was named President of MEI.
In February 2008, Twin Cities Business magazine featured MEI
in an article “Going Back Up,” which underscored that MEI did
all the right things to achieve a turnaround. Later in 2008, MEI
purchased Highland Electric which offers electrical contracting
for residential and commercial properties. The Highland Electric
office and warehouse is now the central location for MEI’s field
operations in the Twin Cities. The following year, MEI purchased
Badger Elevator in Milwaukee which expanded its elevator
contracting business to Milwaukee and throughout eastern
Wisconsin. In November 2010, MEI purchased Dynatron Elevator
in Kansas City, Kansas. Even in a down economy, MEI’s prospects
were still rising thanks to the dedication of the ownership,
leadership and employees toward continuous improvement.
In 2011, MEI purchased Lagerquist in Duluth, Minnesota and
in 2012 purchased the backlog of CEMCO elevator from Otis.
In 2013, MEI expanded its office locations and opened a plant
in Pennsylvania to better serve the USA’s northeast region. In
February 2015, MEI purchased Precision Elevator Service in
Denver, CO which expands our elevator contracting business. In
2015, MEI headquarters in Mankato, MN also added 20,000 sq ft
to their manufacturing facility.

In 1974, MEI built its first building - a 32ft. x 54 ft. structure that
served as a shop and warehouse and was heated with a wood stove.
The office and bathroom were still in the family home.

CRITERIA FOR REVIEW
Section 9-2-14, B.R.C. 1981, “Site Review”
(a)Purpose: The purpose of site review is to allow flexibility and encourage innovation in land use
development. Review criteria are established to promote the most appropriate use of land,
improve the character and quality of new development, to facilitate the adequate and
economical provision of streets and utilities, to preserve the natural and scenic features of
open space, to assure consistency with the purposes and policies of the Boulder Valley
Comprehensive Plan and other adopted plans of the community, to ensure compatibility with
existing structures and established districts, to assure that the height of new buildings is in
general proportion to the height of existing, approved, and known to be planned or projected
buildings in the immediate area, to assure that the project incorporates, through site design,
elements which provide for the safety and convenience of the pedestrian, to assure that the
project is designed in an environmentally sensitive manner, to assure that the building is of a
bulk appropriate to the area and the amenities provided and of a scale appropriate to
pedestrians, and to set requirements for additional height, density, and intensity that provide
additional benefits to the community beyond the underlying zoning.
(h)Criteria for Review: No site review application shall be approved unless the approving agency
finds that:
(1) Boulder Valley Comprehensive Plan:
(A) The proposed site plan is consistent with the land use map and the service area map and,
on balance, the policies of the Boulder Valley Comprehensive Plan.
The site is currently designated as Regional Business on the land use map of the Boulder Valley
Comprehensive Plan (BVCP). There is no maximum residential density under this designation. The
description from the BVCP is below. The proposal meets the intent of the land use designation with
a mix of uses and a design that will activate the street.
The current proposal is consistent with the following BVCP goals and policies:
•2.03 Compact Development Pattern
•2.16 Mixed Use & Higher Density Development
•2.20 Role of the Central Area
•2.33 Sensitive Infill and Redevelopment
ATTACHMENT B
Agenda Item 5A Page 283 of 360
• 2.36 Physical Design for People
• 2.41 Enhanced Design for All Projects
(B) The proposed development shall not exceed the maximum density associated with the
Boulder Valley Comprehensive Plan residential land use designation. Additionally, if the
density of existing residential development within a three-hundred-foot area surrounding
the site is at or exceeds the density permitted in the Boulder Valley Comprehensive Plan,
then the maximum density permitted on the site shall not exceed the lesser of:
There is no maximum residential density for the Regional Business land use designation.
N/A (i) The density permitted in the Boulder Valley Comprehensive Plan, or,
Not applicable; the density of the existing residential development within 300 feet
does not exceed the density permitted in the BVCP.
N/A (ii) The maximum number of units that could be placed on the site without waiving or
varying any of the requirements of Chapter 9-8, "Intensity Standards," B.R.C.
1981.
Not applicable; see above.
(C) The proposed development’s success in meeting the broad range of BVCP policies
considers the economic feasibility of implementation techniques require to meet other site
review criteria.
The development would not be rendered infeasible in meeting the BVCP policies or the
site review criteria based upon the requirements and recommendations made within
these comments.
(2) Site Design: Projects should preserve and enhance the community's unique sense of place
through creative design that respects historic character, relationship to the natural environment,
multi-modal transportation connectivity and its physical setting. Projects should utilize site design
techniques which are consistent with the purpose of site review in Subsection (a) of this section
and enhance the quality of the project. In determining whether this subsection is met, the approving
agency will consider the following factors:
(A) Open Space: Open space, including, without limitation, parks, recreation areas, and
playgrounds:
(i) Useable open space is arranged to be accessible and functional and incorporates
quality landscaping, a mixture of sun and shade and places to gather;
The site design is urban in character and has a small on-site open space
requirement. The proposed project utilizes urban forms of on-site open space with
an open courtyard and private balconies and patios to serve the residences.
Agenda Item 5A Page 284 of 360
Outdoor seating for a restaurant use could spill into the interior courtyard or onto
Pearl Street, with a revocable permit from the city. All open spaces will receive a
mixture of sun and shade based on the building orientation. The open spaces are
appropriate considering the urban context and proximity to the pedestrian mall.
(ii) Private open space is provided for each detached residential unit;
Each residential unit would have a private balcony, some on the exterior of the
building and some facing the interior courtyard.
(iii) The project provides for the preservation of or mitigation of adverse impacts to
natural features, including, without limitation, healthy long-lived trees, significant
plant communities, ground and surface water, wetlands, riparian areas, drainage
areas and species on the federal Endangered Species List, "Species of Special
Concern in Boulder County" designated by Boulder County, or prairie dogs
(Cynomys ludiovicianus), which is a species of local concern, and their habitat;
A detailed tree inventory was provided. There are no healthy long-lived trees,
special status species, or other natural features present on the site.
(iv) The open space provides a relief to the density, both within the project and from
surrounding development;
The public courtyard, private balconies, and rooftop decks on the setback third
story will provide a relief to the density. The interior court on the ground level will
be a place for people to gather along East Pearl Street. The courtyard contains
an ornamental tree to anchor the center of the court and provide shade and an
enhanced “feature wall”. The main façade element along Pearl Street is broken
up by a paseo that provides a visual connection through the building to an open
interior court in the center of the building that is open to the sky. The 15 foot
landscaped setback on the alley will also provide relief to the residential
neighborhood to the north.
(v) Open space designed for active recreational purposes is of a size that it will be
functionally useable and located in a safe and convenient proximity to the uses to
which it is meant to serve;
Not applicable; no spaces are designed for active recreational purposes. Active
programming is not appropriate considering the urban context and proximity to
the pedestrian mall. Outdoor seating for a restaurant use could spill into the
interior courtyard or onto Pearl Street, with a revocable permit from the city. Each
residential unit would have a private balcony or patio.
N/A (vi) The open space provides a buffer to protect sensitive environmental features
and natural areas; and
Agenda Item 5A Page 285 of 360
Not applicable; there are no known sensitive environmental features or natural
areas within this developed urban site.
(vii) If possible, open space is linked to an area- or city-wide system.
The existing walkways along Pearl, 17th, and 18th streets are all part of a city-
wide, interconnected network of sidewalks that connect to the larger multi-modal
system.
(B) Open Space in Mixed Use Developments (Developments That Contain a Mix of
Residential and Nonresidential Uses):
(i) The open space provides for a balance of private and shared areas for the
residential uses and common open space that is available for use by both the
residential and nonresidential uses that will meet the needs of the anticipated
residents, occupants, tenants and visitors of the property; and
Both private open spaces (balconies and decks) and common open space
(interior courtyard) has been provided. The courtyard will be open to residents,
employees, and visitors to the site. The proposed courtyard will be a flexible
space with movable seating that will allow for small gatherings, etc. that will be
enjoyed by the residents and occupants, as well as the larger neighborhood.
The spaces meet the anticipated needs of the development.
(ii) The open space provides active areas and passive areas that will meet the
needs of the anticipated residents, occupants, tenants and visitors of the
property and are compatible with the surrounding area or an adopted plan for
the area.
Passive areas are provided for residents on private balconies and decks. The
interior courtyard will be programmed for passive use but could also be utilized
for active purposes for residents, occupants, tenants, and visitors to the site.
Outdoor seating for a restaurant use could spill into the interior courtyard or onto
Pearl Street, with a revocable permit from the city.
(C) Landscaping
(i) The project provides for aesthetic enhancement and a variety of plant and hard
surface materials, and the selection of materials provides for a variety of colors
and contrasts and the preservation or use of local native vegetation where
appropriate;
Landscaping is planned to be installed according to the Landscape Plan (see Attachment A). The project includes planting areas within the courtyard and in
the alley. The selection of plants and their relationship to the surrounding
developments are aesthetically attractive and provide a relief to the proposed
density. The proposed landscaping includes three ornamental trees, shrubs, and
Agenda Item 5A Page 286 of 360
a variety of understory planting appropriate to the surrounding use and ecological
niche. Mature street trees will remain on Pearl Street. Patterned concrete in the
courtyard will give the space a more human scale.
(ii) Landscape design attempts to avoid, minimize or mitigate impacts on and off site
to important native species, healthy, long lived trees, plant communities of special
concern, threatened and endangered species and habitat by integrating the
existing natural environment into the project;
Landscape materials will be incorporated in the stormwater and water quality
facilities. No important native species, plant communities of special concern,
threatened and endangered species, or habitat would be impacted on this
project. A tree will anchor the center of the public court and provide shade when
needed, while thoughtful lighting and a unique “feature wall” will provide comfort
and interest to the space.
(iii) The project provides significant amounts of plant material sized in excess of the
landscaping requirements of sections 9-9-12, "Landscaping and Screening
Standards," and 9-9-13, "Streetscape Design Standards," B.R.C. 1981; and
The applicant intends to preserve the existing, healthy public street trees along
both Pearl Street and provide additional landscaping that will be in excess of the
requirements.
N/A (iv) The setbacks, yards and useable open space along public rights of way are
landscaped to provide attractive streetscapes, to enhance architectural features
and to contribute to the development of an attractive site plan.
Not applicable; the code requirements and design guidelines within the downtown
is for buildings to address the street, particularly along the first floor where zero
setbacks are desired. Landscape is not provided or desired in the front yard in
this context.
(D) Circulation: Circulation, including, without limitation, the transportation system that serves
the property, whether public or private and whether constructed by the developer or not:
(i) High speeds are discouraged or a physical separation between streets and the
project is provided;
High speeds are generally discouraged in the existing urban context, with
narrow right of way and on-street parking. There is a relatively wide sidewalk
area from face of curb to the building to accommodate the pedestrian. Existing
mature street trees will be preserved and will provide a strong physical
separation between Pearl Street and the proposed building.
(ii) Potential conflicts with vehicles are minimized;
Agenda Item 5A Page 287 of 360
The existing context limits vehicular conflicts. Vehicular access to the site is via
the alley, with an auto lift to the parking garage. Defined street crossings are
provided on Pearl, 17th, and 18th streets. The proposed auto lift will allow cars
to safely enter the alley with minimal potential conflicts with pedestrians or
cyclists
(iii) Safe and convenient connections are provided that support multi-modal
mobility through and between properties, accessible to the public within the
project and between the project and the existing and proposed transportation
systems, including, without limitation, streets, bikeways, pedestrianways and
trails;
A detached walkway and trees in grates will remain along Pearl Street. This
provides a certain pedestrian travel way that helps to channel pedestrians
along the building frontages, while removing them from vehicular travel along
the streets. The proposed building will have two new public entrances on Pearl
Street. Private building entrances will be located on the alley for use by
residents and employees.
(iv) Alternatives to the automobile are promoted by incorporating site design
techniques, land use patterns, and supporting infrastructure that supports and
encourages walking, biking, and other alternatives to the single-occupant
vehicle;
The site design and infrastructure support and encourage walking, biking, and
other alternatives to the SOV. The proposal includes 40 long-term secure bike
parking spaces for residents, guests, and employees of the commercial uses in
the secured parking garage, where 24 spaces are required. Twelve short-term
bike spaces will be provided adjacent to the site along Pearl Street on inverted
"u" bicycle racks. The site is located within the urban fabric of downtown and is
well connected to the larger transit and multi-modal network. The applicant is
providing only the required minimum of one parking space per dwelling unit.
The “horizontal mix” of uses within downtown Boulder, with residential and
commercial uses, encourages alternatives to single occupant vehicles.
(v) Where practical and beneficial, a significant shift away from single-occupant
vehicle use to alternate modes is promoted through the use of travel demand
management techniques;
As described above, the applicant has submitted a Transportation Demand
Management (TDM) plan. The proposal includes 40 long-term secure bike
parking spaces for residents, guests, and employees of the commercial uses in
the secured parking garage, where 24 spaces are required. Twelve short-term
bike spaces will be provided adjacent to the site along Pearl Street on inverted
"u" bicycle racks. The short-term parking will offer a convenient and accessible
area to park bicycles for customers and other visitors. Since the property is
located in CAGID employees of the commercial uses will be eligible for the
Agenda Item 5A Page 288 of 360
downtown employee EcoPass program. In addition, an alternative
transportation fund will be established for the residential units for a period of
three years to cover the costs of EcoPasses or other programs that support
and encourage alternatives to the single-occupant vehicle. The site is highly
accessible, with transportation facilities and a large number of destinations that
can be reached within a 15-minute walk (grocery stores, parks, restaurants,
and transit stops). There are existing bus stops on Pearl Street near the
intersection with 18th Street. The Downtown Boulder Bus Transit Station is less
than half a mile to the southwest. This regional transit center is served by at
least 15 local and regional transit lines. The site is well connected to the larger
multi-modal network with detached sidewalks, designated bike routes, and bike
lanes. The applicant is providing only the required minimum of one parking
space per dwelling unit.
(vi) On-site facilities for external linkage are provided with other modes of
transportation, where applicable;
See (iv) above.
(vii) The amount of land devoted to the street system is minimized; and
The amount of land devoted to the street system is the minimum necessary to
provide access to the parking areas, a drop-off / pick-up area, and a service
area.
(viii) The project is designed for the types of traffic expected, including, without
limitation, automobiles, bicycles, and pedestrians, and provides safety,
separation from living areas, and control of noise and exhaust.
The proposed project is an urban configuration of the building adjacent to the
pedestrian walkway, which enhances the pedestrian experience. Bicycles and
vehicles will be accommodated on the surrounding street system and in the
alley. A submitted traffic impact analysis concludes that the proposed
development can be accommodated by the existing roadway network without
significant impacts to service levels.
(E) Parking
(i) The project incorporates into the design of parking areas measures to provide
safety, convenience, and separation of pedestrian movements from vehicular
movements;
Parking is provided in a below grade parking garage. An auto elevator is
proposed to provide access to the garage. Removal of surface parking lots in
the alley will help with the safety and convenience of pedestrians and cyclists
traveling through the alley. A delivery/auto queueing area is provided next to
Agenda Item 5A Page 289 of 360
the elevator entry for vehicles waiting for the elevator in the event that it is
occupied.
(ii) The design of parking areas makes efficient use of the land and uses the
minimum amount of land necessary to meet the parking needs of the project;
The proposed below grade parking and auto elevator makes efficient use of
the land. The applicant is providing the minimum number of one parking space
per dwelling unit. The site is located within the Central Area General
Improvement District (CAGID), with approximately 4,000 parking spaces
included in the district. The provision of parking is the minimum amount
necessary. The parking is designed to provide covered, secure bike parking
as well as vehicular parking.
(iii) Parking areas and lighting are designed to reduce the visual impact on the
project, adjacent properties, and adjacent streets; and
The parking is located below grade with a single door to the auto elevator,
reducing the visual impact on the project, adjacent properties, and adjacent
streets. No lighting is expected to create adverse visual impacts. Any lighting
installations will be subject to the Outdoor Lighting requirements of
Section 9-9-16, B.R.C.
N/A (iv) Parking areas utilize landscaping materials to provide shade in excess of the
requirements in subsection 9-9-6(d), and section 9-9-14, "Parking Lot
Landscaping Standards," B.R.C. 1981.
Not applicable; It is not possible to provide landscaped areas within the
underground parking.
(F) Building Design, Livability, and Relationship to the Existing or Proposed
Surrounding Area
(i) The building height, mass, scale, orientation, architecture and configuration
are compatible with the existing character of the area or the character
established by adopted design guidelines or plans for the area;
The urban orientation of the planned three-story, 38-foot high building is
compatible with the character of the area where two- and three-story buildings
occur to the east and west along Pearl Street in the DT-2 district. There are
several buildings within a two-block radius of the subject site that are three
stories, both within the DT-2 zoning district as well as the adjacent MU-3
zoning district. The proposed project was found to be consistent the
Downtown Urban Design Guidelines for the interface zone.
Agenda Item 5A Page 290 of 360
(ii) The height of buildings is in general proportion to the height of existing
buildings and the proposed or projected heights of approved buildings or
approved plans or design guidelines for the immediate area;
The height of the proposed building is in general proportion to the height of
existing buildings in the immediate area. The design guidelines for the
interface zone state: “Buildings should appear similar in height, mass, and
scale to other buildings in the area. At the same time, it is important to
maintain a variety of heights. While the actual heights of buildings are of
concern, the perceived heights of buildings are equally important. One, two
and three story buildings make up the primary architectural fabric of the
Downtown, with taller buildings located at key intersections.” The proposed
height of 38 feet is in general proportion to the height of existing buildings to
the south and west and is consistent with the intent described above.
(iii) The orientation of buildings minimizes shadows on and blocking of views from
adjacent properties;
The location of the site is within the established urban context, where the
BVCP identifies the area as the “highest intensity” of land use. Similarly, there
is an established grid pattern of streets and an urban street face with buildings
built to the public right of way. Given the established land use typology, some
degree of shading during deep winter months, along with constrained views
toward the Flatirons is typical for the downtown and has been since the town
was established. Further, the adjacent buildings to the east and west are not
subject to the Solar Access standards since the DT-2 district is within Solar
Access Area III, where because of planned densities, topography or lot
configurations or orientations, uniform solar access protection for south yards
and walls or for rooftops may unduly restrict permissible development. The
applicant has submitted a solar access study demonstrating that shadows will
not unduly impact residential properties to the north in the RMX-1 district.
(iv) If the character of the area is identifiable, the project is made compatible by
the appropriate use of color, materials, landscaping, signs, and lighting;
The building height, mass, scale, orientation, architecture and configuration
are compatible with the existing character of the area and the character
envisioned by the Downtown Development Guidelines. See analysis for
criteria (ii) and (ii) above. The building design is contemporary with traditional
references. The base of the structure is emphasized with added wood details
around the storefront window openings. Per the applicant, more modern
storefront proportions like a tall and open first floor and large display windows
are married with more traditional elements like wood column detailing at the
retail level and goose-neck light fixtures and signage.
(v) Projects are designed to a human scale and promote a safe and vibrant
pedestrian experience through the location of building frontages along public
Agenda Item 5A Page 291 of 360
streets, plazas, sidewalks and paths, and through the use of building
elements, design details and landscape materials that include, without
limitation, the location of entrances and windows, and the creation of
transparency and activity at the pedestrian level;
The use of ground floor storefront windows, wood column detailing, and
traditional proportions in the building layout and fenestration helps to establish
continuity in the established human scale along Pearl Street. The commercial
spaces open directly onto Pearl Street. The public paseo also provides a
visual connection through the building to an open public court in the center of
the building. As stated above, the project will promote a safe and vibrant
pedestrian experience with a relatively wide sidewalk area to accommodate
the pedestrian.
(vi) To the extent practical, the project provides public amenities and planned
public facilities;
The project provides enhanced facilities along Pearl Street, with additional
short term bike parking. There are no planned public facilities that impact the
site.
(vii) For residential projects, the project assists the community in producing a
variety of housing types, such as multifamily, townhouses and detached single
family units, as well as mixed lot sizes, number of bedrooms and sizes of
units;
The attached residential units contribute to the variety of housing types in the
community. The units range from 562 to 2,424 square feet in area.
(viii) For residential projects, noise is minimized between units, between buildings,
and from either on-site or off-site external sources through spacing,
landscaping, and building materials;
The residential units are proposed above the street level, which will help to
minimize noise from off-site external sources. The applicant states that the
cast in place concrete construction will reduce the transfer of sound vertically
between the commercial spaces and residential units. Double stud demising
walls will help with horizontal noise movement between units on upper levels.
Exterior walls on the east and west will be built out of CMU and will greatly
reduce any noise impacts between buildings.
(ix) A lighting plan is provided which augments security, energy conservation,
safety, and aesthetics;
A preliminary lighting plan shows outdoor lighting that provides for security,
safety and aesthetics. Pedestrian scale fixtures are used where possible.
Lighting design will activate the courtyard as usable open space. Final lighting
Agenda Item 5A Page 292 of 360
will be evaluated at the Technical Documents review process. All proposed
lighting fixtures must comply with the Outdoor Lighting Ordinance.
(x) The project incorporates the natural environment into the design and avoids,
minimizes, or mitigates impacts to natural systems;
The project site is a redevelopment of developed property and does not
include any significant elements of the natural environment that could be
incorporated into the design. Necessary water quality improvements in the
form of rain garden planters will be provided.
(xi) Buildings minimize or mitigate energy use; support on-site renewable energy
generation and/or energy management systems; construction wastes are
minimized; the project mitigates urban heat island effects; and the project
reasonably mitigates or minimizes water use and impacts on water quality.
The project will be required to meet the 2020 City of Boulder Energy
Conservation Code, which is a localized version of the 2018 International
Energy Conservation Code that is 20% more efficient than the national code.
The structure will be designed to be “solar ready” to support the additional
loads of a photo voltaic solar array.
(xii) Exteriors or buildings present a sense of permanence through the use of
authentic materials such as stone, brick, wood, metal or similar products and
building material detailing;
The materials proposed include cast in place concrete, stucco (three coat
system), CMU, wood look laminate cladding, cement board siding, and
aluminum storefront windows. The concrete will present a stone-like quality or
depth. These materials are considered authentic and in character with that of
the interface of downtown. The proposed building uses a simple palette of
materials that emphasize the base of the structure with added wood details
around the storefront window openings.
(xiii) Cut and fill are minimized on the site, the design of buildings conforms to the
natural contours of the land, and the site design minimizes erosion, slope
instability, landslide, mudflow or subsidence, and minimizes the potential
threat to property caused by geological hazards;
The site is generally level. The overall slope will be maintained. There will be
some excavation necessary to create the basement area of the proposed
building.
N/A (xiv) In the urbanizing areas along the Boulder Valley Comprehensive Plan
boundaries between Area II and Area III, the building and site design provide
for a well-defined urban edge; and
Agenda Item 5A Page 293 of 360
N/A (xv) In the urbanizing areas located on the major streets shown on the map in
Appendix A of this title near the Boulder Valley Comprehensive Plan
boundaries between Area II and Area III, the buildings and site design
establish a sense of entry and arrival to the City by creating a defined urban
edge and a transition between rural and urban areas.
(G) Solar Siting and Construction: For the purpose of ensuring the maximum potential for
utilization of solar energy in the City, all applicants for residential site reviews shall place
streets, lots, open spaces, and buildings so as to maximize the potential for the use of
solar energy in accordance with the following solar siting criteria:
(i) Placement of Open Space and Streets: Open space areas are located
wherever practical to protect buildings from shading by other buildings within
the development or from buildings on adjacent properties. Topography and
other natural features and constraints may justify deviations from this criterion.
The site is in an urban context and the new building will reflect that context
and traditional urban design pattern by building up to the public right of way on
Pearl Street. The building is oriented to take advantage of solar energy
systems and can accommodate PV systems. The adjacent buildings to the
east and west are not subject to the Solar Access standards since the DT-2
district is within Solar Access Area III, where because of planned densities,
topography or lot configurations or orientations, uniform solar access
protection for south yards and walls or for rooftops may unduly restrict
permissible development. The applicant has submitted a solar access study
demonstrating that shadows will not unduly impact residential properties to the
north in the RMX-1 district.
(ii) Layout and Building Siting: Lots are oriented and buildings are sited in a way
which maximizes the solar potential of each principal building. Lots are
designed to facilitate siting a structure which is unshaded by other nearby
structures. Wherever practical, buildings are sited close to the north lot line to
increase yard space to the south for better owner control of shading.
See above. The positioning of building on the site is conducive to solar
access. The proposed project is part of a developed urban context and the
orientation of the lots will not be modified by the proposal.
(iii) Building Form: The shapes of buildings are designed to maximize utilization of
solar energy. Buildings shall meet the solar access protection and solar siting
requirements of section 9-9-17, "Solar Access," B.R.C. 1981.
The building is designed with a flat roof that will not be shaded by adjacent
structures. The building is setback from the alley 15’ to allow the properties
to the north better solar access.
Agenda Item 5A Page 294 of 360
(iv) Landscaping: The shading effects of proposed landscaping on adjacent
buildings are minimized.
There are no identified conditions where proposed plantings could negatively
affect solar access of buildings in the future. Proposed alley trees are
ornamental and will not unduly affect adjacent properties.
N/A (H) Additional Criteria for Poles Above the Permitted Height: No site review application
for a pole above the permitted height will be approved unless the approving agency finds
all of the following:
N/A (I) Land Use Intensity Modifications
N/A (J) Additional Criteria for Floor Area Ratio Increase for Buildings in the BR-1 District
N/A (K) Additional Criteria for Parking Reductions: The off-street parking requirements of
section 9-7-1, “Schedule of Form and Bulk Standards,” B.R.C. 1981, may be modified as
follows:
N/A (L) Additional Criteria for Off-Site Parking: The parking required under section 9-9-6,
"Parking Standards," B.R.C. 1981, may be located on a separate lot if the following
conditions are met:

Design Advisory Board (DAB) Design Review Summary
DAB reviewed the design proposal for The Navy at 1737 Pearl St on two occasions,
March 6, 2019 and September 11, 2019. The project review occurred twice due to the change in
scope of the September 11, 2019 proposal to include an additional parcel and increased building
square footage. The March 6, 2019 review included 3 board members and the PB liaison. 6
members of the public attended the review and spoke during open comment. The September 11,
2019 review included 5 board members and the PB liaison. 1 member of the public attended and
spoke during the open comment. The full DAB information packets, board minutes and public
participation comments are available in the links referenced above.
March 6, 2019
Fig. 1 Perspective of Pearl Street Elevation March 6, 2019
DAB focused their review and recommendations on each façade.
•Front façade – The board said there is not a clear consensus on how to do the third floor
(“two over one” vs. the “one over two”). The board had mixed feelings regarding the
ATTACHMENT C
Agenda Item 5A Page 296 of 360
2
historic pattering but agreed it could go more contemporary. The first floor could use
some adjustments. More open space is not necessary nor appropriate but a great first floor
will be necessary because that will represent the public open space. Most of the board
approved of the third floor stepping back on the front facade. They agreed the second-
floor parapet could be extra tall on the front and back of the structure. There was a split
regarding a natural looking material vs. stark white. The masonry material and detailing
are appreciated. There was division on the board regarding materiality. Suggestions
included more detailed contemporary treatments, modern durable materials, less wood,
possibly steel and painted masonry.
• Back Façade – The board was split regarding the proposed setback. The board was
comfortable with the eight-foot upper level setback. They would like the applicant to hold
to the fifteen feet setback in the alley. The agreed the rear eyebrow element should to be
adjusted. The board was in favor of screening the upper level but not strongly required.
The board suggested pushing the first floor back and bringing the second floor out to help
with congestion in the alley. They suggested being creative on this façade given the
visibility. They did not want to see stucco used on the second floor.
• Sides – The board agreed the sides could be fairly blank, however it would be nice to see
some art, decorated or something paint related. How the corners are treated will be
important.
• Parking – All board members were in support of the proposed parking solution.
• The board would like this project to come back to DAB after being reviewed by Planning
Board and more details are in place.

The following tables include the summary DAB recommendations from September 11, 2019
organized into review topics and the staff comments of the current design proposal analyzing
conformance to those recommendations.
URBAN DESIGN CHARACTERISTICS:
DAB Comments Staff Analysis of Current Proposal
• The board was in favor of the proportions and
front façade and the addition of the extra floor.
The proportions are consistent with the board
recommendations.
• Regarding the upper floor, the board approved of
the stepping back and the proportions.
The step back of the third floor is consistent
with the board recommendations.
• The board was in favor of the reduction to a ten-
foot setback on the third floor in the proposed
areas.
The setback of the third floor on the Pearl
Street elevation is consistent with the board
recommendation and varies between 10-15’.
ARCHITECTURAL COMPOSITION AND PATTERNING:
DAB Comments Staff Analysis of Current Proposal
• The board leaned toward keeping the left side of
the arch as proposed.
The entry arch is consistent with the board
recommendation and design presented on
Sept 11, 2019.
• The board approved of the sides of the building.
The sides of the building are consistent with
the board recommendations and include
Agenda Item 5A Page 298 of 360
4
illustrating a possible mural on the east side.
• The board asked that more thought be put into
the alley design especially regarding privacy for
the neighbors, and the patio setbacks and widths
of patios. The board agreed that frosted glass for
the patio railings would be acceptable but not
clear. Stepping the upper floor back in the rear of
the building would be preferred. Large trees in
the rear would help mitigate privacy.
The rear elevation has been revised to
include a redesign of the balconies to include
frosted glass. The building does not include
setting back the upper floor of the rear
elevation. 2 Trees are indicated in the plans
for the rear elevation.
ARCHITECTURAL DETAILS:
DAB Comments Staff Analysis of Current Proposal
• The proposed archway had the approval of the
board, but there was some concern regarding the
detailing of the interior material. The material
needs to be more thought out, substantial, and
durable.
The material composing the arched entry is
two layers of materials built up in a casing
fashion around the entry tunnel. This detail
includes several levels of reveal working
back to the wall material lining the tunnel.
• The arcade at the retail level, clad with wood on
the inside, also had the board divided. It may be
dependent on how the inside of the arch is
treated.
The design includes wood-like material on
the inside of the arch entry to the courtyard.
• The focal feature in the courtyard needs work. Focal feature will be further designed further
in the Technical Document phase.
• The interior courtyard plinth should wrap around
inside the courtyard.
The interior courtyard plinth does not extend.
Instead the concrete and wood archway is a
built up casing element around the wood
entry portico that terminates on the feature
wall with the same wood material and an
feature element.
• Darker doors in the rear on the first level to
match the darker cladding would be preferred.
The rear door and entry area have been
expressed with dark paint and wood cladding
to accentuate this area.

Dear Sloan:
Please accept this letter as an expression of full support for the proposed development of a
mixed use building at 1727 and 1737 Pearl St. As a business owner in the City of Boulder I
feel that this proposed development will have overwhelming positive impact on the City as
a whole. I understand that there are a few neighbors in opposition of the project and thus
it is in jeopardy. I would hope that City Staff will take the global view of the project and
realize its net positive impacts on our community and the vibrancy of business in Boulder.
As a construction professional I know all too well that no matter what the project there will
always be impacts on the surrounding areas. Our trade creates noise, traffic and dust. This
is unpleasant during the construction process, but the end result is an improvement from
the previous situation almost without exception. Please take the long view of this situation
and realize that the neighbors will be happier in the long run with a vibrant mixed-use
facility next door.
Please feel free to contact me if you have any questions at 720.485.5792 or

Sloan,
I am reaching out to share my support of the project for 1727 and 1737 Pearl Street. I recently
reviewed the plans and mockups and as an owner of commercial office space in Boulder I found it to
be a very considerate improvement and in keeping with the look and feel I value in Boulder.
The elevation is an attractive addition to 17th street block. With Retail on the first floor, residential
on the 2nd and 3rd floors and the open interior offer the right mix of amenities and thoughtfully look
to meet the needs of those living in or visiting Boulder. The third floor open decks provide a visually
appealing look and are very much appreciated in keeping the buildings feel ‘soft on the street’.
Improvements like this project are ones I welcome to my Boulder and I am happy to provide my
support for the project.
Keep Smiling,
Chris

Sloan,
I believe this project is creative, interesting, fresh and unique. It is great to have a courtyard
for all people involved. This creates more of a sense of community. The patrons, businesses
and residents can use the courtyard. Perhaps bands and community functions can happen
there? The city can possibly host outdoor meetings there. I do not see that the building should
be set back further than the 15' in the alley as that would detract from the courtyard.
Diversity is a good thing. The massing can be visually pleasing with some easy local
artwork, but I do not think that needs to be spelled out. It would be fun to have a contest or
something. Plus once the trees grow in the ally that will change the overall visual simplicity.

Sloan,
Among other Boulder properties, we own 1945-65 28th Street just off of 26th and Pearl Street, and
accordingly, we frequent many businesses along East Pearl. I have reviewed the proposal for the
1727-37 Pearl Street property and am writing to express my support.
In particular, I think the proposal does a nice job of fitting into the existing neighborhood while also
adding something that is unique but still harmonious. I was glad to see that the third level of the
building is set back, and I really like the pass-through from the street into the courtyard. The single
biggest thing that can be done to make a development fit in on East Pearl is to get the pedestrian
experience right. This proposal does a great job of that by activating the street at the ground floor
with commercial space, keeping the pedestrian feel to two-stories with the third-floor setback and
providing the unique pass-through into the courtyard, which really creates a unique permeability.
The proposed coloration will also create something that is unique but not in conflict with
surrounding properties.
For these reasons, I enthusiastically encourage the City to approve this project.
Best regards,
Bruce Dierking

Hi Sloane,
We received the development notice for 1737 Pearl St. Our home is an alley house at 1722 Spruce St, which is
between Pearl and Spruce. The project sounds like an upgrade, our only concern is construction vehicles /

Hi Sloane,
Thank you for your presence at last night's 1737 pearl redevelopment meeting. This morning I
stood in our kitchen watching the sunrise. Though I was reassured that this new development
won't take away from our direct light, it truly will. This is disheartening for us. It was very
clear that we have no say in the height and development because they're entitled to 38'. Can
you please guide me to where in the plans show the north facing shadows and shading of the
alley?
As I mentioned last night, there needs to be a weight restriction of trucks for the alley to
ensure the residential homes sewer lines aren't compromised by heavy concrete mixing trucks.
An alternative to weight restrictions would be to repave the alley before the construction
begins to create a thicker barrier, protecting the residential sewer lines. Please let me know
your thoughts on this.
I would like to be present at the design meeting, so as soon as you have a date please let me
know.
Cheers,

Hi Sloane,
I had an Eco-Cycle meeting the night of the neighborhood meeting so I was not able to attend the neighborhood
meeting for 1737 Pearl. I live within 600’ of the proposed project and received notice of the meeting.
Please consider my comments and questions.
The city Development review page has old plans and new plans for this project. Is there anyway to differentiate
between the current plans and the older ones?
Will this project be scheduled for a site review or a call up?
This sentence from the design guidelines would be a good one to measure the project success by - “Consideration
should be given to creating an appropriate interface to the residential development and minimizing impacts.”
I do support the mix of residential and retail and the applicant should be aware that the porches/balconies on the
north facade abut an established Residential Mixed Density zone. Lights and noise from porches should be
mitigated. It would be less intrusive on the north side residences if a third story was stepped back from the required
alley set back.
Many Boulderites enjoy walking the alleys so making them pleasant, with green, and art would be much
appreciated. I attached a photo of some recent art on this very alley.
Maybe even a place to sit for the weary restaurant/retail workers taking a break. Just an idea.
This area of Pearl Street has closing hours for restaurant/retail and I was glad to see mention of this in the staff
review notes. The area is a thriving retail/restaurant area and the closing hours have worked well for the
neighborhood - who are patrons too.
The applicant’s written statement says they want their residents to avoid the exhaust from the cars in the alley and
that is why they have residents on the upper floors. Maybe they can do an all electric car project as part of their
TDM to mitigate the exhaust issues for adjacent neighbors from this project. It would be a win-win and be trend
setting.
I though this sentence in the staff review was very appropriate and I hope the applicant will use this comment to
help guide design revisions: “.... by encouraging architectural solutions that are visually pleasing, reflective of
contemporary times yet stylistically appropriate to the context, and compatible in scale and character with their
street”.
There are several areas of the code that address design and compatibility and even though the owner says they want
to avoid the ‘monotonous red brick’, which is found up and down East Pearl, the dark blue and white pallet seems
too artificial and out of place - it looks like ‘coastal nautical’. This will be a building with a long facade spanning
several lots and will be very prominent. It would be interesting to see it divided into several sections like other
buildings on the street have done. A material besides stucco would look more permanent and more in character with
this area. Quite frankly, the stucco buildings are the least successful in this area. I would suggest taking walk up and
down east Pearl where there are some good examples of brick with metal that harken back to the commercial and
light manufacturing uses - yet they have a contemporary twist.
The building should not be given set back modifications along the north where it abuts the RMX-1 zone. The solar
Agenda Item 5A Page 312 of 360
access shadow should not encroach on the northern properties as this would limit their potential for solar access. The
mechanical on the roof should be calculated into this height. Society is changing and individuals are taking
responsibility for their carbon foot print. This includes those who want to transition off fracked gas and on to
electricity supported by solar in their own yards. Please make sure this possibility is preserved.
Has the applicant considered PV panels on the roof? It could mitigate the need for some of the mechanical roof top
structures. I believe there are a few buildings in the 1500 and 1600 block of Pearl (north side) that do not have
mechanical on the roof. They are mixed use also. Hopefully they are not using gas for mechanical functions.
There is high ground water in this area and with underground parking I would want to make sure any pumping, and
discharge, does not flood the alley or the properties to the north. The Nature Conservancy property on Spruce near
Folsom in a high ground water area, with pumping, is closed due to mold. Groundwater and discharge is a real
concern in the neighborhood.
Thanks for taking my comments into consideration.
Best,
Crystal Gray

Hello Sloan,
My name is Peter Hoglund and I'm an owner of Frasca Food and Wine and Pizzeria Locale at
1738 and 1730 Pearl.
I wanted to take the time to write to you in support of the development of 1737 Pearl Street.
We have been an anchor of East Pearl for 15 years and we welcome the development as long
overdue. We have reviewed the design with Adam Wertz and believe that it would be a
beautiful addition to East Pearl. The addition of the updated design aesthetic to the
neighborhood, professional looking retail/restaurant space and knowing Adam make me
confident that his vision for this block is beneficial to the city, neighborhood and business
community.
I am available for any questions or additional letters of support. We have been a tenant of
East Pearl long before most of the current businesses were located here. We take our
responsibility as stewards seriously and after careful review, we agree that the development
presents tremendous positive benefit for the city.
Thank you for your time.

Dear Sloane,
As I may have mentioned to you previously, my family and I own 1836 & 1844 Pearl Street,
and I'd like to reach out and provide my approval and support for the project that has recently
been proposed at 1737 Pearl St. I believe the project will establish a much needed landmark
for the east end of Pearl Street, and is a good fit for the surrounding neighborhood and
community. Currently, there are several buildings on East Pearl that are old and dilapidated,
many of which sit vacant and divert both locals and tourists from this part of town. I believe
this project will serve as a catalyst for additional redevelopment of neighboring properties,
which will serve to bolster the economic vitality of this area and provide an overall benefit to
the community as a whole.
I'm pleased to see a 3 story concept designed within the current height limitations, and feel
that the residential units inclusive of large decks and outdoor gathering space fill a significant
void in the current downtown housing market.
I may not be able to make it to all the meetings, but want to express my support and approval
for this project.
Please feel free to contact me with any questions or comments.

March 9, 2019
Planning Board Members,
This week I attended, along with several of my neighbors, the DAB meeting on the development at 1737
Pearl Street – the “Navy Redevelopment” (LUR2018‐00073). While the meeting’s discussion
demonstrated the design prowess of its members, it entirely neglected the fact that this development
is in a “transitional” zone between commercial and residential. I respectfully request that the Planning
Board broaden its consideration to include these critical impacts on residential areas as this
development sets an important precedent for these transition blocks along east Pearl. Below are
details from the meeting’s dialogue.
During the public comment period, neighbors expressed concern with mass, scale, design, privacy and
alley congestion. All such comments were guided by the hope that Boulder’s urban design guidelines
regarding transition zones might be considered since the development is immediately adjacent to
residential alley access and backyards and is explicitly in a transition zone.
Many Board members spoke in favor of maximizing density, some believed the building’s 3‐story façade
offered a unique break in the parade of 15‐foot setbacks – an opportunity for something unique. Some
expressed concern with alley congestion while others noted such congestion is simply a characteristic of
alleys. The issue of privacy for neighbors was a non‐starter and one Board member even noted that
contemporary trends are such that urban residential buildings often have large windows, reducing
privacy but increasing solar.
These comments aren’t necessarily wrong and some certainly align with Boulder’s broader urban
development goals – but they entirely neglect the fact that this development is proposed for a
transitional zone, zones which receive particular attention in the urban design guidelines. Below are
excerpts from these guidelines, with the development design’s entire neglect subsequently noted.
Transitional zone guideline: Encourage sensitive design along the edge where the Downtown
commercial area abuts residential neighborhoods.
o The building virtually maximizes mass through requests for exceptions and by including
a reduced set‐back. It also includes a front façade which increases perceived height and
a rear façade that encroaches on privacy and offers no architectural interest. The
request for an exception on the alley setback would intensify congestion in an area that
provides residential access and is already highly congested. On the set‐back, the original
design’s is only 8 feet, while guidelines request that designs “maintain the historic or
predominant building set back line” … and “For new structures that are significantly
taller than adjacent buildings, upper floors should be set‐back a minimum of 15 feet
Agenda Item 5A Page 317 of 360
from the front façade to reduce perceived height.” These guidelines are even outside of
transitional zones.
Transitional zone guideline: Emphasize a clear distinction between the commercial and
residential interface areas.
o Simply put, there is absolutely nothing about this design that offers a distinction – it is a
continuation of mass and scale from the downtown core, even with a reduced setback.
Please consider carefully.
Transitional zone guideline: Maintain the diversity in building type and size and respect the
adjoining residential character.
o Again, no sense of “respect” for adjoining residential character. None.
Transitional zone guideline: Discourage adverse impacts from noise, night lighting, poor
building design, and commercial service areas on adjacent residential neighborhoods.
o The request for an exception at the alley demonstrates lack of concern. The loss of alley
space will intensify the challenge of commercial service areas on the immediately
adjacent neighbors and access to their homes.
Open space is also lost – a 75% reduction is requested. The Board members appeared to agree that
open space is simply a challenge for urban developers to provide – intriguing to me as a Boulder
resident since our urban design guidelines explicitly note:
Consider the quality of open space incorporated into new and renovated buildings … Well
programmed plazas, courtyards, outdoor seating and dining areas on or adjacent to open
spaces and pedestrian routes are encouraged.
o These are the guidelines even outside of the transitional zone – and yet they were
entirely neglected – in fact, countered – in the Board’s dialogue! I would argue that in a
transitional zone, open space is actually a key pathway through which design can be
sensitive to, and respectful of, the adjoining residential character. Simply look across the
street from this development to see a public plaza adjacent to Frasca.
In all, at issue for the Planning Board, the requested modifications have important impact on the
adjoining neighboring areas, which per the guidelines, are supposed to be considered with in
development plans.
ASK: additional setback in alley.
o IMPACT: increased congestion in alley that provides access to adjoining homes.
ASK: three stories instead of two.
o IMPACT: additional housing unit with views to neighboring windows and yards.
ASK: open space reduction.
o IMPACT: maximized mass with lack of plaza, courtyard, seating would help with scaling
down to the residential area, offering a more “clear distinction” between commercial
and residential interface areas.
ASK: four parking places instead of required six.
o IMPACT: the surrounding residential blocks do not have paid parking and congestion is
already intense.
Agenda Item 5A Page 318 of 360
Finally, I also balk at the contention that the development will provide “much needed housing” in
Boulder. Indeed, housing is in short supply, but not this type of housing. The wealthy have options.
This is a precedent‐setting redevelopment within this transition zone and I respectfully request that the
Planning Board consider Boulder’s wisdom in development of this guideline:
Encourage sensitive design along the edge where the Downtown commercial area abuts
residential neighborhoods.
In so many ways, this development simply does not.

Sloane,
My comments can probably be summarized in the request for an answer to one question.
· What about this design is responsive to the fact that it is in a transitional zone?
In other words, in what way(s) is this design *different* than if the building had been designed for
an area that wasn’t a transitional zone? I can think of two potential answers: 1) the proposed
opaque balcony railings, and 2) the setback of the third story although that may have been required
for other reasons.
I can imagine, however, that both of these would also be common in non-transition buildings given
implications for in-building resident privacy and also the building shadow. It’s also important to note
that the shadow from this proposed development still has tremendous impact on alley neighbors
and, therefore, hasn’t even offered a workable “transition” from the perspective of the neighboring
residences.
In all, I wonder if there are sufficient design considerations to meet the city’s thoughtful designation
of transition zones? Additionally, is it not necessary to consider other aspects of the design (e.g.
front façade)?
Thank you,
Lori Hunter

Hi Sloan -
I am writing to express my strong support for the 1737 Pearl St. Project. I have looked at and
been interested in many downtown condo and/or mixed use projects, and believe this one is
definitely at the top. This east end of Pearl is slowly being revamped, and the 1737 Pearl St.
Project will stand out as a premier addition to the neighborhood.
Obviously much thought has gone into the project design. This is evidenced in the attractive
exterior design as shown in the renderings, the three-story building fits well with the other
buildings on both sides of this block, the enticing and useful central courtyard provides
useable ground floor space for everyone and allows ample light into the second and third floor
residences, and the elimination of the alley utility lines and the inclusion of extra
landscaping/trees are pluses and improvements to the neighborhood. Also, the existing alley
parking areas behind the current buildings are an eyesore and this new development will clean
all of this up.
I trust the City will approve this wonderful, thoughtful project.
Thank you,
Tom Martini

I talked to the Architect. A little concerned on granting a variance on a back alley as
cars are big and need a turning radius. So the variance is beneficial to the developer
but what does it offer the property owner directly north? And, what is the benefit to
the city of Boulder?
IF and it's an IF you said no variance and it required the developer to move the
northern edge towards Pearl to meet the requirements what would that do? He has
less "space in his building to sell/ rent" BUT, he meets the code. Interesting
thoughts....
Is granting that variance a precedent or are they asking for a variance that is a
consistently granted variance for that area? Is the code incorrect and that is what
actually needs to be changed?
Now, I would say a LOT of the code is poor and is hinders logical development.
But that argument will never be won by a citizen. You all in the planning
department are way off on what you let happen and what you restrict.I'm not
political at all but I do own property and overall I am very unhappy with every and
all planning discussions, meetings, and decisions that I attend and eventually see the
results of.
Recently the Berkeley Model has been thrown at me on a project. My response. If I
wanted to live in Berkeley I would move there! Their model stinks (if you call it a

Dear Sloan,
Thank you for notifying the Whittier Neighborhood of this project. I have spoken to a number
of residents and wanted to get preliminary comments into you by the January 4, 2019 deadline
although I plan to contact residents that live on Spruce Street directly north of the project
along the alley for additional comments. If it is possible I would like to set up a meeting
between you and those residents so you can explain the project and answer questions.
Following are some initial comments:
The Downtown Design Guidelines (attached below) apply to this project since it is in the
Interface zone and abuts a residential zone. The objectives of the Interface zone, page 25,
seem appropriate and should be followed as well as guidelines (p. 26) 2.1 and 2.2.
This residential area of the Whittier Neighborhood was surveyed, by Landmarks, and found to
be eligible for an Historic District so extra care of the alley treatment is warranted. Although
the residential area is not an Historic District many of the structures were build around the turn
of the 19th century and trigger a Landmarks review of alterations to the facade and to older
alley structures.
Having the six residential units, on the 2nd and 3rd floors, is preferable to offices on the upper
floors as the impacts will be less and they will provide much desired housing and ‘eyes on the
alley’. Housing also contributes to a vibrant downtown neighborhood so it is appreciated and
it would be good to have the developer consider meeting their affordable housing requirement
(20%) on site.
If the retail space, on Pearl, is to be used for a restaurant/cafe/bar, it should close by 11 pm as
the other restaurants in this area do. I believe that there are criteria that require a use review,
to set size and hours of restaurants, if they are larger than 1500 square feet or will stay open
after 11 pm. Can you clarify if the retail will be a restaurant please? It is unfortunate that the
neighborhood will lose two local businesses, so hopefully the owners will try to attract other
local businesses by having smaller retail spaces.
The applicant is requesting to have the rear set back (abutting the residential zone) reduced
from 15’ to 12’8”. It is preferable to keep the setback at 15’ to minimize the shadows cast
from onto the residential properties to the north. It would be helpful to have a shadow analysis
of both the 15’ and 12’8” set backs. A larger set back will also help with space for deliveries
to the first floor retail without blocking the entire alley.
Please see the mixed use building at 1637 Pearl which has a 33’ set back from the alley -they
also have alley landscaping which would be nice to see on this site. Many people use the
downtown alleys for biking and walking and the alleys should be more attractive.
Agenda Item 5A Page 323 of 360
Does the requested open space reduction, from 15% to 4%, cause the building to be pushed
closer to the alley? If your staff analysis can address this that would be appreciated.
The third floor should also be stepped back from the alley setback - this includes the balconies
The plans show the 3rd floor directly above the second floor further impacting the shading of
the properties north of the alley. The closed ends of the alley balconies give the impression of
a continuous wall. Stepping the building back on the alley side will also make for a more
interesting alley facade. The Design guideline 2.1 (C) address “Design all sides of the
building including the alley elevations” - of course the building is designed on the alley side
but it could be improved.
Additionally, reading the guidelines they discuss a 15 foot set back to the third story on the
front facade. I don’t believe the plans show that is occurring.
The Transportation Demand Management (TDM) Plan that the applicant submitted does not
address if Eco-passes will be provided to the 6 residential units. Can you please clarify if that
is correct? It would be desirable for them to have Eco-passes since this area has great bus
connections.
Hopefully the building will be wired for rooftop solar as well as for electric vehicles.
Thank you for considering these comments.
Respectfully,

Sloane —
Thanks for having the neighborhood meeting on Jan 29, 2019 for the above
project.
I believe that this project is contingent on a substantial "open space" reduction — based on a
large monetary “contribution” in years past to the downtown Pearl St. Mall (not to CAGID).
But at the neighborhood meeting, Jeff Dawson, the architect, said to me that he was unable to
find any such contribution, although, he thought it might be there “somewhere” in the records.
This project should not go forward unless and until this issue is resolved.
Please note that the existing zoning adjacent to an interface zone specifies a “two
story building.” I think it is important for the architect to supply a street
rendering of the 17th-18th block (north side) to show that the buildings there now
are almost completely one and two-story buildings. The only exception is the
Coburn Building, one building east of 17th — and this building only has a small
gable end, setback, at the 38’ height.
Since there may be major changes in the project, is still a good idea to go to DAB
in early March?
What is the possibility of the Planing Board calling this up for a concept review?
Also, a number of us were put off by "threats” from the architect and developer
that they would just go ahead and build (an admitedlly ugly!) 2-story building at
the full “allowed” height of 38 feet. Can they do this?
Note that the proposed “filled” in third story setback is completely inappropriate — this
creates at “wall” along Pearl Street, and cuts against any third story setback advantages.
The proposed “elevator” parking will create a hazard for cars and pedestrians in the alley.
With a proposed building setback of only 11 feet from the alley, a driver of a car exiting the
elevator will in most cases be unable to see passing cross traffic behind. Of course a flashing
light or small siren might help — but this would only make things much worse for residential
neighbors to the north of the alley.

Sloane –
Thanks for holding the recent developer’s neighborhood meeting.
The proposed third floor balconies on the north side will eliminate backyard
privacy for the four residential properties closest to the development.
The solar shading analysis, while maybe technically correct, is almost certainly
very misleading to citizens: it assumes that there is a 25’ tall “solar fence”
around the property -- and only shadows going above this fence are shown.
Put another way, it assumes that all properties to the north have a 25’ tall yard
“plateau” above the alley!
One of the recurrent points that was brought up is that 38’ tall proposed
building -- up to the maximum permitted height -- and going from Pearl St.
almost to the alley in the rear. The building is just too large. Not only will it
block important views (and the sun!) to the south, but it will also create icy and
snowy alley conditions in the winter -- making the alley hazardous to both
pedestrians and vehicles.
In addition, with the “elevator” parking system, and only 11’ to the alley,
drivers backing out of the elevator will in most cases not be able to see passing
vehicles and pedestrians in the alley. This could be alleviated somewhat with a
small “siren” or flashing red light, but this would make things much worse for
Agenda Item 5A Page 328 of 360
the historic neighborhood to the north of the alley.
Please note that the existing zoning adjacent to an interface zone specifies a
“two story building.” I think it is important for the architect to supply a street
rendering of the 17th-18th block (north side) to show that the buildings there
now are almost completely one and two-story buildings. The only exception is
the Coburn Building, one building east of 17th — and this building only has a
small gable end, setback, at the 38’ height.
Significantly, the developer provided no street elevations of this block to the
north side of Pearl.
Note that the proposed “filled” in third story setback is completely
inappropriate — this creates at “wall” along Pearl Street, and cuts against any
third story setback advantages.
Furthermore, we believe that this project is contingent on a substantial "open

Ms. Walbert - This concerns the site review of the application for the redevelopment of 1737
Pearl Street (Navy Redevelopment). I am the homeowner at 1728 Spruce Street, across the
alley from the north side proposed redevelopment.
First, I’d like to commend the City of Boulder development review web site for the
completeness of the information available. It was very helpful. Looking at the architectural
plans, it appears that the north balconies of the two residential units on the 3rd floor will have
a view down into my backyard, and of the rear bedroom windows of my house. It is
understood that in the higher-density areas of the city, privacy is often compromised. But I am
curious to learn what planning regulations exist that constrain the creation of new lines of
sight into existing properties, and if a consideration of any such guidelines has been applied to
this proposed development.
I appreciate your time and look forward to hearing from you.
Best regards,
Ray

development. My interest is still very high and I appreciate the continued communication. I
spoke to a neighbor who attended, Fran Bagenal, and I am encouraged by what she had to say

concern with the proposed building remains having an alley setback that is in line with being
in an interface zone.
This email is to let you know that I have the same question as Crystal concerning site review

Building Design
Sloane Walbert, 303-441-4231
1. The site is located within the Interface Area of Downtown. The urban design objectives for the Non-Historic and
Interface Areas, among others, are to reinforce the character of Downtown as a pedestrian place by encouraging
architectural solutions that are visually pleasing, reflective of contemporary times yet stylistically appropriate to the
context, and compatible in scale and character with their street. Consideration should be given to a less traditional
approach to the design, which is contemporary yet stylistically appropriate. The guidelines contain several examples of
contemporary infill development envisioned for the Non-Historic and Interface Areas.
2. In support of the site review criteria and Downtown Urban Design Guidelines the building entrances on the ground
floor facing Pearl Street should be fully visible with primary entry features.
3. In support of the Downtown Urban Design Guidelines consideration should be given to emphasizing the rear building
entrance on the alley. Refer to guideline 2.1-E below.
E. Design all sides of the building including alley elevations.
1. Well designed rear building entrances, windows, balconies, and planting areas are encouraged.
2. Improve rear or side alley elevations to enhance public access from parking lots and alleys.
3. Where buildings are built to the alley edge, consider opportunities for alley display windows and secondary
customer or employee entries.
4. Materials utilized on the primary elevation are to extend, or wrap, around building corners onto the secondary
elevations extending back at least the width of a structural bay.
5. Screening for service equipment, trash, or any other rear-of-building elements should be designed as an
integral part of the overall design. Where intact, historic alley facades should be preserved along with original
features and materials.
4. All mechanical equipment must be screened from view, unless such screening conflicts with the function of the
mechanical equipment. The screening must be consistent with the building design, colors, and materials (Section 9-
7-7(a), B.R.C. 1981). Ensure that the railing on the rooftop is the minimum amount necessary. In addition, refer to
guideline 2.1-D below.
D. Minimize the visibility of mechanical, structural, or electrical appurtenances. Use low-profile mechanical units
and elevator shafts that are not visible from the street. If this is not possible, set back or screen rooftop
equipment from view.
Corrective Action: Revise plans accordingly.
5. Consideration should be given to utilizing metal railings rather than architectural block walls for the individual roof-top
decks on the west and east elevations to reduce the perceived bulk / mass of the building.
6. Site review criterion (2)(F)(xii): “Exteriors of buildings present a sense of permanence through the use of authentic
materials such as stone, brick, wood, metal or similar products and building material detailing.”
Corrective Action: Please provide details on the proposed stucco siding, including coat system, finish, etc., to
demonstrate that the building material meets this criterion.
7. The guidelines for the Interface Area focus on sensitive design of development that abuts residential neighborhoods.
Refer to guidelines below. Consideration should be given to creating an appropriate interface to the residential
development and minimizing impacts.
Urban design objectives for the Non-Historic and Interface Areas: Encourage sensitive design along the edge
where the Downtown commercial area abuts residential neighborhoods.
Urban design objectives for the Non-Historic and Interface Areas: Maintain the diversity in building type and size,
and respect the adjoining residential character.
2.1-B.4. For projects located in the Interface Area, construct buildings three floors or less and consider the
adjacent residential height, mass, and scale.
8. Provide digital and hard copies of color building elevations with a legend or key indicating materials. Label the CMU
on the elevations.
Agenda Item 5A Page 336 of 360
1737 PEARL ST Page 3 of 10
9. The final selection of building materials and finishes, including paint, windows, doors, exterior cladding, and other
architectural features are to be noted on plans. Submit material samples and indicate the finish for the cast-in-place
concrete. For projects with a unified material palette, submit a materials board that is no larger than 24” x 36”.
Securely mount and label small-sized samples of all the exterior building materials and finishes, e.g. paint chips,
cladding, window finish, etc. Clearly label the project name, address, case number and building (if applicable) on the
board.
10. Provide a full wall section and schedule for the Pearl Street and rear alley elevations, including information from any
below grade construction to roof transition details. Provide window section / profiling details within the Pearl St.
section.
11. Provide details indicating the construction of the storefront window system.
12. Provide color perspective renderings or sketches illustrating views of the building, street character, and the
relationship of the project to surrounding buildings from Pearl Street. All sketches or renderings should accurately
reflect the scale and materiality of the proposed building.
13. Provide a site section to illustrate grade changes across the site, including private streets, public right-of-way
improvements, structured parking, and landscape.
14. Retractable awnings are proposed to extend into the public right-of-way. Staff recommends removing these from the
plans or identifying them as future elements so that they are not part of the site review approval. A revocable permit
will be necessary for any encroachments in the public right-of-way (refer to Chapter 6, B.R.C. 1981) . The revocable
permit for awnings that contain signage require tenant signatures and proof of insurance.
Drainage
Will Johnson, 303-441-3273
1. Per 7.13 (C)(2) of the City of Boulder Design and Construction Standards "Projects and developments that disturb
less than 1 acre of land and do not increase the impervious area or runoff shall provide storm water quality facilities to
the extent practable." Per the provided Preliminary Drainage Report no storm water quality facilities are being
provided. Some form of storm water quality shall be provided to meet this requirement, and may be address through
the following considerations:
• Water quality for surface runoff using "Best Management Practices"
• Minimize Directly Connected Impervious Areas (MDCIA)
• Detention ponding facilities
• Localized facilities for roof drain downspouts and parking lots (raingardens, swales, etc.)
2. City policy seeks to limit the use of sidewalk chase drains and allow their use only in situations where no other
reasonable alternative exists. Chase drains are generally not desirable due to associated maintenance burden and
adverse effects on pedestrian safety. Please investigate routing all stormwater runoff from the site towards the alley,
and/or other alternatives that eliminate the use of the sidewalk chase. Use of a sidewalk chase must meet all the
following criteria, which must be addressed in the Drainage Report:
a. All reasonable on-site modifications which could reduce or eliminate the need for a chase drain have been
determined to be ineffective or unreasonable, and
b. The property is not located adjacent to a storm sewer or similar conveyance or cannot reasonably extend a
storm drainage facility to abut the property, and
c. Any groundwater discharge must conform with Section 8-2-8, "Discharging Water Prohibited" B.R.C., 1981.
Per Section 8-2-8(a), no owner, lessee, or occupant of property shall cause or permit water to flow upon any
sidewalk, street, alley, or other public right of way so as to impair the use of such place, when the weather is
such that the water may be frozen into ice, where the drainage is such that it may create a hazard to persons
or property, or where it may cause damage to any public property or facility.
d. Discharge from the chase drain will not adversely affect downstream properties.

David Thompson, 303-441-4417
1. Please revise the demolition and preliminary grading plan sheets to show the limits of the Pearl Street sidewalk to
which must be replaced in order for the removal of the existing fence and for the installation of the utilities shown on
the preliminary utility plan.
Will Johnson, 303-441-3273
2. The proposed canopies shown on sheet SR-A1.01 cannot be approved as shown. Please ensure the plans call out
the requirement for a revocable permit for these improvements. An attachment detail will be required to be provided at
the time of building permit. Please reference Section 8-6-6, "Requirements for Revocable Permits".
Land Use – Addressing
BrieAnna Simon, 303-441-1896
Please pick one of the two existing addresses. The proposed building will only have one street number.
Landscape
Elizabeth Judd, 303-441-3138
Landscape is met with preservation and protection of existing public street trees and associated infrastructure. Care is
needed to avoid any damage to the city irrigation system.
Please review and correct typos in the written statement regarding the number of proposed units (8 vs 6). Also review
and correct the open space summary table on sheet SR-A1.01. It is not clear how any of the open space numbers are
reached. Open space per table 8-1 indicates that the greater of the residential or nonresidential standards shall be met;
Section 9-9-11 states that for buildings at 38 feet in height 15% open space is required (vs. the residential private open
space only).
Parking
David Thompson, 303-441-4417
1. In accordance with Section 9-2-14(c) B.R.C. 1981 please revise the development review application to request a
modification to the "off-street loading standards" contained in Section 9-9-9 B.R.C. 1981. A modification is necessary
because the proposed loading zone blocks the parking area / parking area circulation of the site. Please revise the
project's written statement to discuss the design vehicle (truck) that will serve the site and how the loading space will
operate and managed in conjunction with the site's parking area for staff's review and concurrence.
2. In order to verify the design criteria for long-term bicycle parking is being met per Section 9-9-6(g) B.R.C. please
revise the site plan to show how the bicycles will be parked in the bike storage area and how the design criteria for
covered and lighting are being met.
3. Staff appreciates the three (3) short-term bicycle racks shown to be installed in the public right-of-way adjacent to the
site. However, in order to maintain the areas for pedestrian circulation between the on-street parking, the parking
kiosk and the business it is staff's preference to install the bike racks in the northwest quadrant of the Pearl Street &
18th Street intersection. As such, please revise the site plan to include a note stating 3 inverted "u" bicycle racks will
be installed in the public right-of-way at the northwest quadrant of the Pearl Street & 18th Street intersection which is
approximately fifty-feet from the site. Installing the bicycle racks will require the relocation of the existing bicycle
racks and removing the existing bench which will be picked-up by Community Vitality. This work will be required to
be shown on the future technical documents for the site.
4. Please revise the site plan to show the required vehicle backing distance is being provided for the vehicle parking per
Section 9-9-6(d)(2) B.R.C. 1981. The useable width of the alley can be used in meeting the required vehicle backing
distance.
5. Staff appreciates the data sheet that was submitted for the proposed automated car parking system, but additional
information is needed for staff's review. Please revise the written statement to: (1) include a maintenance and repair
plan for the system; (2) how funds will be set aside or collected for the maintenance and repair of the system; (3) for
vehicles that can't be accommodated by the system where do those vehicles park and (4) where will the switch
cabinet be located and will it be necessary to provide heat to the switch cabinet. The applicant can expect additional
comments from staff once the additional information is provided for staff's review.

Sloane Walbert, 303-441-4231
6. Parking spaces located above and below grade in the parking system are considered tandem parking, which do not
meet the city’s parking standards. Therefore, a 33.3% parking reduction is necessary to allow four spaces, where six
are required. Staff supports the mechanical parking system; However, additional information is necessary regarding
the operation and maintenance of such system and possible noise impacts.
Plan Documents
Sloane Walbert, 303-441-4231
1. Provide the building and parking setbacks, dimensioned from property lines on the Site Development Plan.
2. Site review criterion (2)(F)(xi): “Buildings minimize or mitigate energy use; support on-site renewable energy
generation and/or energy management systems; construction wastes are minimized; the project mitigates urban heat
island effects; and the project reasonably mitigates or minimizes water use and impacts on water quality.”
Corrective Action: Please submit an energy efficiency plan that demonstrates how the proposed building meets this
criterion. Is it possible to incorporate EV charging into the mechanical parking system? What are the plans for rooftop
PV?
3. Revise the site plan to include topographic contours and include the uppermost point of the roof and the low point
within 25 feet.
4. Revise the written statement to address the criteria for parking reductions in Sections 9-2-14(h)(2)(K) and 9-9-6(f),
B.R.C. 1981.
5. It appears that the trash enclosure and bike storage areas meet the definition of “floor area” in Section 9-16-1, B.R.C.
1981. Please correct or explain how these areas meet the definition of “uninhabitable space.” In addition, please add
any walkways required for primary or secondary egress by Chapter 10-5, "Building Code," B.R.C. 1981 to the rear
portion of the building as floor area.
Site Design
Sloane Walbert, 303-441-4231
1. Per Table 8-1, B.R.C. 1981, the required usable open space for mixed use developments is the greater of either the
residential or nonresidential standards that result in the greatest amount of open space. In this case the greater
amount would be fifteen percent of the total land area for the nonresidential use (1,058 square feet). Per Section
9-9-11(f)(1), B.R.C. 1981, individual balconies for the residential use may count toward the requirement up to twenty-
five percent of the required open space (264 square feet). It is not possible to modify the 25% limitation for
individual balconies in the DT zone districts. Please add an asterisk or footnote to the Land Use Summary Table and
Open Space Summary Table explaining why only 264 square feet is counted as usable open space for the site. In
addition, update all plan documents to reflect the correct open space reduction (refer to comments below).
2. Pursuant to Subsection 9-2-14(h)(2)(I)(i)(a), B.R.C. 1981 the density of a project may be increased in the Downtown
(DT) districts with a reduction in the open space requirements in site review. Subsection (b) expands on this
allowance to state that the open space requirements in all Downtown (DT) districts may be reduced up to one
hundred percent through site review. Any land use intensity modification must meet all criteria of Subsections
9-2-14(h)(2)(I)(ii)(a) to (c). Criterion (c) specifies allowable site design features for open space reductions and the
associated allowable reduction percentages. It appears that the proposal does not meet site design feature (1) for a
100% reduction. Based on city records, the property was not specially assessed for the Pearl Street Mall (1737 Pearl
was not in the initial assessment district established in 1977). In addition, it does not contribute funding to capital
improvements on the Pearl Street Mall. Please clarify whether the property made assessments or other contributions
to another public park in close proximity to meet this criterion. The only other applicable site design feature is #2,
which allows for a 5% reduction for “architectural treatment that results in reducing the apparent bulk and mass of
the structure or structures and site planning which increases the openness of the site”. Please update proposal
accordingly.
Agenda Item 5A Page 339 of 360
1737 PEARL ST Page 6 of 10
3. Consideration should be given to the site and open space design and how the proposal meets design guideline 2.1-I
(below). Refinement to the design is necessary to ensure that the proposal meets the site review criteria on open
space (criteria in (h)(2)(A) and (B)), the open space standards in Section 9-9-11, B.R.C. 1981, and the Downtown
Urban Design Guidelines.
2.1-I. Consider the quality of open space incorporated into new and renovated buildings. When appropriate to the
context, integrate the surrounding open spaces into the building design. Well programmed plazas, courtyards, outdoor
seating and dining areas on or adjacent to open spaces and pedestrian routes are encouraged.
Transportation Demand Management
David Thompson, 303-441-4417
Staff does not concur with the project's TDM Plan because: (1) it doesn't include a TDM Plan for the residential units;
(2) the pedestrian enhancements discussed in Table 2 do not enhance the pedestrian experience and therefore are not
considered pedestrian enhancements; (3) as discussed Via is not considered a TDM strategy and (4) it doesn't commit to
TDM strategies for the commercial space. To address this comment please revise the TDM Plan to (1) separate the
residential TDM Plan from the non-residential TDM Plan; (2) discuss the additional TDM strategies being implemented
by the project for the non-residential use from what is provided by CAGID; (3) discuss the two tables in the text of the
TDM Plan; (4) provide a legend for figure 2 or substitute the figure for a detailed discussion in the text of the TDM Plan
and (5) submit a TDM Plan that commits to implement strategies rather than a consideration or where appropriate. The
applicant can expect additional comments from staff with the resubmittal of the TDM Plan.
Zoning – Outdoor Lighting
Sloane Walbert, 303-441-4231
1. Note, the lighting plan is reviewed at Site Review to evaluate compliance with the site review criteria. The following
comments are directed at compliance with the Outdoor Lighting Standards in Section 9-9-16, B.R.C. 1981. Staff will
evaluate the lighting plan against the site review criteria once these comments have been addressed.
2. Please change the line width/color to clearly show the property lines on the photometric plan.
3. Revise the lighting fixture schedule to include the color rendering index; the general style of the light fixture such as
cutoff, lantern, coach light, etc.; shielding information such as house side shields, internal, and/or external shields;
control descriptions including type of controls (timer, motion sensor, time clock, etc.). Note, dimming or shut off are
recommended for lighting after close of business.
Refer to the definitions below:
Full cutoff light fixture means a light fixture with a light distribution pattern that results in no light being projected at
or above a horizontal plane located at the bottom of the fixture.
Fully shielded from view means that the light emitted by a light fixture is not visible from adjacent streets and
properties.
Fully shielded light fixture means a light fixture that provides internal or external shields or louvers that prevents
light being emitted by the fixture from causing glare or light trespass impacts.
4. Revise the photometric plan to show the location of light fixtures in the street right-of-way within ten feet of the subject
property (Section 9-9-16(g), B.R.C. 1981).
5. Revise the photometric plan to provide the maximum light levels on the east and west property lines at the rear of the
property to demonstrate that light levels emitted by ES1 fixtures do not exceed 0.2 at property line (Section 9-9-16(d)
(1), B.R.C. 1981).
6. Revise the photometric plan to include all exterior areas with lighting, including areas under canopies, balconies, or
other nonenclosed or partially enclosed areas (definition of maximum allowable light level in Section 9-16-1, B.R.C.
1981). Note, light levels may not exceed 2.0 in outdoor storage areas (Section 9-9-16(e), B.R.C. 1981).
7. Please expand on the note about the light loss assumptions on the photometric plan. For example: “The light levels
depicted are the maximum initial horizontal illuminance for exterior areas measured at one hundred hours of
operation, in foot-candles at grade level.”
8. Per Section 9-9-16(d)(1), B.R.C. 1981, the maximum light level at any point on a property line shall not exceed 0.1
footcandles adjacent to a residential zone. This level is exceeded on the north, property line. Please correct.
Agenda Item 5A Page 340 of 360
1737 PEARL ST Page 7 of 10
9. Pursuant to Section 9-9-16(d)(1), B.R.C. 1981, the maximum light level on a property line shall not exceed 0.2
footcandles in nonresidential zones. This level is greatly exceeded on the south property line. Per Subsection
9-9-16(d)(1)(A), B.R.C. 1981, the light emitted by light fixtures mounted on a structure built within five feet of a public
street right-of-way or sidewalk shall not exceed the maximum allowable light levels for "pedestrian areas" (3.0
footcandles). The maximum allowable light level shall include any existing or proposed street or pedestrian lighting
located within the right-of-way. If the applicant would like to use this provision of the code a separate photometric
plan must be submitted for this portion of the site to include light emitted from street lighting and to demonstrate
compliance with this section. The plans must demonstrate that the levels diffuse at the curb line of the Pearl Street
right-of-way to 0.2 footcandles. Note, any lighting located within the public right-of-way requires a revocable permit
and may not be supported by the city.
10. Please include the color temperate for all fixtures on the fixture schedule and remove the note regarding
temperature. Per Section 9-9-16(d), B.R.C. 1981 all new exterior lighting must have a correlated color temperature
(CCT) below 3,001 degrees Kelvin.
11. The maximum allowable light level for building entries is 5.0 footcandles. There are several readings on the property
adjacent to Pearl Street that exceed this limit. Please correct.
12. The maximum uniformity ratio (maximum to minimum) for this zone district is 10:1. The area defined as “front of
building” greatly exceeds this amount. In addition, please provide the uniformity ratio for the area defined as “back of
building”.
13. It appears that fixture EW1 is considered architectural lighting. Please note the IESNA classification for fixture EW1.
Building facade lighting exceeding 900 lumens shall be fully shielded, aimed downward, and mounted as flush to a
wall as possible (Section 9-9-16(d)(4)(B), B.R.C. 1981). Any building facade lighting that is measurable at the ground
level shall be included in the maximum allowable light levels.
14. For clarity, please revise the keynote that states that the height of the building is 41’-4”. The proposed building height
is 38’-0”.
Zoning – Solar Access
Sloane Walbert, 303-441-4231
The Residential - Mixed 1 (RMX-1) zone district is located to the north, across the alley. When the adjacent lot is located
in another solar access area, that lot is protected by the solar fence that corresponds with its zoning district. Properties
within the RMX-1 zone district are within Solar Access Area II, which is designed to protect solar access principally for
rooftops in areas.
The submitted shadow analysis shows shadows from the proposed building exceeding those defined as “extent of
shadows from 25’ solar fence,” within the rear yards of the adjacent properties. The rear yard in considered a protected
area, since solar collectors can be located on accessory buildings. Per Section 9-9-17(d), B.R.C. 1981, no person shall
erect an object or structure on any other lot that would shade a protected lot in SA Area II to a greater degree than the
lot would be shaded by a solar fence twenty-five feet in height, between two hours before and two hours after local solar
noon on a clear winter solstice day.
Public streets and alleyways are not protected by solar access regulations. Please revise the shadow analysis so that
the hypothetical shadows to be cast by the 25’ solar fence are measured from the lot lines of the adjacent properties
located in SA Area II NOT the subject property. Each solar fence completely encloses the lot in question.
Note that per Section 9-9-17(d)(2), BRC 1981 , the solar access regulations do not prevent the principal building on a lot
in Solar Access Area III from being erected within the building envelope up to a height of thirty-five feet.
III. INFORMATIONAL COMMENTS
1. Addressing, BrieAnna Simon, 303-441-1896
Once this application has been approved, a Notice of Address Assignment will be prepared, that will include the
Final Address Plat, and sent to the organizations mentioned above. After a 10-day wait period, the addresses will
be finalized if no issues arise. Building permit for new development on the site should be submitted under the new
addresses.
2. Architectural Inspections, Sloane Walbert, 303-441-4231

reviews will require that building architecture, materials and window details are consistent with approvals. The
inspection would occur as a part of the regular building permit inspection process.
Agenda Item 5A Page 341 of 360
1737 PEARL ST Page 8 of 10
3. Area Characteristics and Zoning History, Sloane Walbert, 303-441-4231
The property is located approximately 2.5 blocks east of the Pearl Street Mall. It sits on Lot 11, Block 91 of the
Boulder subdivision, originally platted in 1868. The property was annexed to the city in 1946. The site currently
contains a single-story structure built ca. 1966. The original use was office; today the building contains retail (Red
Letter Books) and restaurant (L’Atelier) uses.
The property is not within a historic district but is located within the Central Area General Improvement District
(CAGID) and Downtown Boulder Business Improvement District (BID). The site is within the Interface Area of
Downtown Boulder and is subject to the Downtown Urban Design Guidelines. The Interface Area is located on the
northern, western, and eastern borders of Downtown. The Interface Areas includes a wide variety of residential
buildings. The area is composed of the blocks that link the core of the Downtown to the surrounding residential
neighborhoods. This area requires special design sensitivities that must be addressed when commercial buildings
are located adjacent to residential areas.
4. Drainage, Will Johnson, Johnsonw@Bouldercolorado.gov, 303-441-3273
A Final Storm Water Report and Plan will be required as part of the Technical Document Review process. All plans
and reports shall be prepared in accordance with the City of Boulder Design and Construction Standards.
5. Drainage, Will Johnson, Johnsonw@Bouldercolorado.gov, 303-441-3273
Floor drains internal to covered parking structures, that collect drainage from rain and ice drippings from parked cars
or water used to wash-down internal floors, shall be connected to the wastewater service using appropriate grease
and sediment traps.
6. Groundwater, Will Johnson, Johnsonw@Bouldercolorado.gov, 303-441-3273
At time of Technical Document Review, the applicant shall submit information (geotechnical report, soil borings,
etc.) regarding the groundwater conditions on the property, and all discharge points for perimeter drainage systems
must be shown on the plan. The applicant is notified that any proposed groundwater discharge to the city’s storm
sewer system will require both a state permit and a city agreement.
7. Inclusionary Housing, Michelle Allen, 303-441-4076
a. Each new residential unit developed on the property is subject to 9-13 B.R.C., 1981, “Inclusionary Housing”
which requires is that all residential developments with 5 or more dwelling units contribute 25 percent (25%) of
the total dwelling units as permanently affordable housing affordable to low/moderate and middle-income
households. The means for satisfying the inclusionary requirement will be reviewed by staff concurrent with any
land use review or for those projects not subject to any land use review, prior to application for a residential
building permit.
b. Due to the small number of for-sale units, the entire development will be treated as rental for IH purposes.
Rental developments may satisfy the inclusionary requirement through the provision of on-site affordable rental
units or comparable existing or newly built off-site permanently affordable rental units or through the dedication of
land appropriate for affordable housing or by payment of a cash-in-lieu contribution.
c. A Unit and Cash-in-lieu Calculator for estimating the Inclusionary requirement for your development may be
found on the city website at www.boulderaffordablehomes.com.
d. Any applicable cash-in-lieu contribution must be made prior to receipt of a residential building permit.
e. Provide unit information consistent with your submittal by filling out and emailing the Affordable Housing Unit
Data Spread Sheet to allenm@bouldercolorado.gov in the unlocked excel format. The spreadsheet may be
found on-line at www.boulderaffordablehomes.com.
8. Land Uses, Sloane Walbert, 303-441-4231
The current proposal is for retail space on the ground floor facing Pearl St., which is a permitted use in the DT -2
zone district. However, note the restrictions on restaurants, brewpubs, and taverns and financial institutions in the
DT-2 district in Sections 9-6-5(b)(1), 9-6-5(b)(4), and 9-6-7(a)(4), B.R.C. 1981.

The Applicant will be required to sign a Development Agreement, if approved. When staff requests, the Applicant
shall provide the following:
a. an updated title commitment current within 30 days; and
b. any additional documentation pertaining to signature authority, as may be necessary.
10. Neighborhood Comments, Sloane Walbert, 303-441-4231
Staff has received comments from several neighboring property owners and residents, which have been forwarded
to the applicant. Depending on the progress of the proposal the applicant may want to consider hosting a
neighborhood meeting.
11. Next Steps, Sloane Walbert, 303-441-4231
Revisions to the plan documents are required. Please address the comments herein and resubmit five (5) hard
copies (only one (1) copy of the drainage and utility reports) and one (1) digital copy of the revised plans to the
front counter of the at the Planning and Development Services Center. The application deadline is 10:00 a.m. on
the first and third Monday of each month to be included in the following review track. Staff is happy to meet with
you to discuss these comments in detail at your convenience.
12. Residential Growth Management System, Sloane Walbert, 303-441-4231
The City of Boulder’s Residential Growth Management System (RGMS) caps annual residential growth at 1% per
year and is managed through an allocation process. The adopted code language can be found in Section 9-14,
“Residential Growth Management System”, B.R.C. 1981. All projects that include residential units, including those
that meet the exemption criteria, must apply for and receive growth management allocations prior to building permit
application.
Note: Starting Apr. 9, 2018 the RGMS process will no longer include approval of the project from the Housing
Division, which is required to submit for building permit. A separate Affordable Housing Case (AHC) is required. If
you not have an AHC case number when you submit for permit, please contact Michelle Allen at 303-441-4076.
13. Review Process, Sloane Walbert, 303-441-4231
Per Table 2-2 of the land use code a concept plan and site review are not required for the project. However, the
proposal meets the thresholds for voluntary site review. The proposal includes modifications to the development
standards, including a modification to the minimum rear yard setback and a 75% open space reduction, which is
considered a land use intensity modification. Per Section 9 2 14(h)(2)(I) of the Land Use Code, the open space
requirements in all Downtown (DT) districts may be reduced by up to one hundred percent pursuant to site review
approval. The site review requires approval by the Planning Board at a public hearing.
The property is subject to the Downtown Urban Design Guidelines and requires review by the Design Advisory
Board (DAB). DAB reviews and applies the guidelines on all projects with a construction value over $25,000 in the
Non-Historic and Interface Areas. The Planning Board applies these guidelines as part of the site review process.
The Design Advisory Board typically meets on the second Wednesday of each month at 4 p.m. in the Municipal
Building Lobby, 1777 Broadway. Please submit the application materials with a project specialist (4 sets of detailed
plans, including elevations, and a CD or thumb drive containing all electronic files, all pages sized 11x17) no later
than 4 p.m. the last Wednesday of the month, two weeks prior to the desired meeting date.
14. Signage, Sloane Walbert, 303-441-4231
Please either remove all signs from the Site Review plan sets or include a notation that all signage will be reviewed
and approved under a separate permit to avoid any potential future confusion. Please note that illustration of a sign
on the plan set does not grant a modification. Please refer to Section 9-9-21 B.R.C. 1981 for sign related
requirements and signage guidelines in the Downtown Urban Design Guidelines.
15. Utilities, Will Johnson, Johnsonw@Bouldercolorado.gov, 303-441-3273
A Final Utility Connection Plan will be required as part of the Technical Document Review process (which must be
completed prior to building permit application). The Final Master Utility Plan (Utility Connection Plan) will be
required to show all existing water service lines and fire lines.

a. The applicant will be required to provide an accurate proposed plumbing fixture count to determine if the
proposed meters and services are adequate for the proposed use.
b. Water and wastewater Plant Investment Fees and service line sizing will be evaluated.
c. If the existing water and/or wastewater services are required to be abandoned and upsized, all new service taps
to existing mains shall be made by city crews at the developer's expense. The water service must be excavated
and turned off at the corporation stop, per city standards. The sewer service must be excavated and capped at
the property line, per city standards.
d. If the building is to be sprinklered, fire line plans must accompany the fire sprinkler service line connection permit
application
20. Utilities, Will Johnson, Johnsonw@Bouldercolorado.gov, 303-441-3273
Trees proposed to be planted shall be located at least 10 feet away from existing or future utility mains and
services.
21. Zoning, Sloane Walbert, 303-441-4231
The property is in the Downtown 2 (DT-2) zoning district, defined as, "A transition area between the downtown and the
surrounding residential areas where a wide range of retail, office, residential, and public uses are permitted. A balance
of new development with the maintenance and renovation of existing buildings is anticipated, and where development
and redevelopment consistent with the established historic and urban design character is encouraged" (Section 9-5-
2(c)(3)(A), B.R.C. 1981).

1. Generally, the revised proposal is an improved design that meets many of staff’s previous comments. The design
works well comprehensively. The entrances on the ground floor facing Pearl Street are fully visible with primary
entry features. Active storefronts engage the street. Quality public and private open space is provided, including an
appropriate buffer to the residential uses to the north with alley trees. The proposal includes a good mix of
residential unit types and sizes.
Agenda Item 5A Page 345 of 360
1737 PEARL ST Page 2 of 8
2. In support of the Downtown Urban Design Guidelines consideration should be given to emphasizing the rear building
entrances on the alley. Refer to guideline 2.1-E below. Clarify whether these entrances would serve as access points
for employees or customers of commercial space. Awnings or material changes would help to meet this guideline
and provide a relief to the proposed stucco cladding.
E. Design all sides of the building including alley elevations.
1. Well designed rear building entrances, windows, balconies, and planting areas are encouraged.
2. Improve rear or side alley elevations to enhance public access from parking lots and alleys.
3. Where buildings are built to the alley edge, consider opportunities for alley display windows and secondary
customer or employee entries.
4. Materials utilized on the primary elevation are to extend, or wrap, around building corners onto the
secondary elevations extending back at least the width of a structural bay.
5. Screening for service equipment, trash, or any other rear-of-building elements should be designed as an
integral part of the overall design. Where intact, historic alley facades should be preserved along with
original features and materials.
3. Submit material samples and indicate the finish for the cast-in-place concrete on a materials board that is no larger
than 24” x 36”. Securely mount and label small-sized samples of all the exterior building materials and finishes, e.g.
paint chips, cladding, window finish, etc. Clearly label the project name, address, case number and building (if
applicable) on the board. Include the stucco details including coat system, finish, etc.
4. Metal guardrails are shown in the public right-of-way. Staff recommends removing these from the plans or identifying
them as future elements so that they are not part of the site review approval. A revocable permit will be necessary
for any encroachments in the public right-of-way (refer to Chapter 6, B.R.C. 1981) . Note, a separate use review will
be required for any restaurant, brewpub, or tavern uses within the commercial space. The review would be either a
conditional use review (administrative) or full use review (public process) depending on the size, hours of operation,
outdoor patio, etc.
5. Consideration should be given to the treatment of the exposed side walls (west and east façades) to make these
appear more interesting while they remain visible.
6. Per the building design requirements for the DT-2 zone district a minimum of 60% of ground floor street frontage
must be window area (Table 7-1, B.R.C. 1981). The window areas must meet the criteria of Section 9-9-3, including
being made of transparent materials, meaning glass, or other similar materials that possess a minimum sixty percent
transmittance factor and a reflectance factor of not greater than 0.25, or otherwise designed to allow pedestrians to
view activities inside the buildings. In applying this requirement, the columns between window areas cannot be
counted in the required 60% window frontage. Thus, it does not appear that the proposal meets these standards.
Please revise as necessary.
Drainage
Will Johnson, 303-441-3273
1. City policy seeks to limit the use of sidewalk chase drains and allow their use only in situations where no other
reasonable alternative exists. Chase drains are generally not desirable due to associated maintenance burden and
adverse effects on pedestrian safety. Please investigate routing all stormwater runoff from the site towards the alley,
and/or other alternatives that eliminate the use of the sidewalk chase. Use of a sidewalk chase must meet all the
following criteria, which must be addressed in the Drainage Report:
a. All reasonable on-site modifications which could reduce or eliminate the need for a chase drain have been
determined to be ineffective or unreasonable, and
b. The property is not located adjacent to a storm sewer or similar conveyance or cannot reasonably extend a
storm drainage facility to abut the property, and
Agenda Item 5A Page 346 of 360
1737 PEARL ST Page 3 of 8
c. Any groundwater discharge must conform with Section 8-2-8, "Discharging Water Prohibited" B.R.C., 1981. Per
Section 8-2-8(a), no owner, lessee, or occupant of property shall cause or permit water to flow upon any
sidewalk, street, alley, or other public right of way so as to impair the use of such place, when the weather is
such that the water may be frozen into ice, where the drainage is such that it may create a hazard to persons or
property, or where it may cause damage to any public property or facility.
d. Discharge from the chase drain will not adversely affect downstream properties.
Review v2 7/26/2019: Please address these points in the Drainage Report. If the City deems that a chase drain is
necessary, it will need to be located on the property line. Please revise the plans as necessary.
2. Trees in rain gardens can reduce effectiveness. Roots can clog underdrains and trunks lower effective area. Per the
Urban Drainage and Flood Control District (UCFCD) Criteria Manual trees in bioretention areas should be avoided. If
these trees are proposed to meet a landscaping requirement, they must be planted outside of the rain garden water
quality growing medium or a cutoff wall must be used to ensure that roots do not grow into the underdrain. Please
increase the rain garden area a minimum of the anticipated area of mature tree trunk cross section. Revise plans as
necessary.
3. Per UCFCD the rain garden filter material must be a minimum of 6", while only 4" is proposed. Please revise the
plans to meet all requirements for bioretention put forth by UCFCD.
4. Based on the provided drainage report the site is currently approx. 72% detained. Per DCS 7.12(C)(4) a maximum of
5% of the site may be undetained. Consider adding detention and water quality in the proposed courtyard, as this is
the source of the majority of the undetained releases. Revise the plans and drainage report as necessary.
Engineering
Will Johnson, 303-441-3273
The proposed metal railings shown on sheet SR-A1.01 cannot be approved as shown. Please ensure the plans call out
the requirement for a revocable permit for these improvements. An attachment detail will be required to be provided at
the time of building permit. Please reference Section 8-6-6, "Requirements for Revocable Permits".

David Thompson, 303-441-4417
1. This is a follow-up on staff's previous comment regarding the bike storage room in the basement. The architectural
plans do not include the design details of the bike storage room to confirm it meets the design criteria contained in
the Boulder Revised Code or how the bicycles will be parked in the storage room. Pursuant to section 9-9-6(g) BRC
1981 please revise the site plan to show how the bicycles will be parked in the bike storage area and how the design
criteria for security and lighting are being met. Please revise the TDM Plan to state employees will have access to
the residential garage to access the bike locker.
Agenda Item 5A Page 347 of 360
1737 PEARL ST Page 4 of 8
2. Please revise the site plans to show where the remaining 10 short-term bicycle parking spaces will be provided on
the site. The short-term bicycle parking must meet the parking standards contained in Section 9-9-6(g)(3) B.R.C.
1981. Per staff's previous comment, staff will support six of the sixteen short-term bicycle parking spaces being
installed in the public right-of-way at the northwest quadrant of the Pearl Street & 18th Street intersection. Please
revise the site plan accordingly
3. Staff would like additional information on the auto elevator prior to concurring with its use on the site. At time of
resubmittal please include the specification / data sheet for the proposed elevator for staff's review and comment.
The applicant can expect additional comments from staff once the additional information is provided for staff's
review.
4. The proposed loading zone is not large enough to accommodate the trucks which will make deliveries to the two
restaurants. Pursuant to section 9-9-9 B.R.C. 1981 please revise the site plans to increase the area of the loading
zone to accommodate the larger trucks expected to make deliveries to the restaurants. The applicant can expect
additional comments from staff once this information is provided and reviewed by staff.
5. Staff is unable to locate the dedicated space for the long-term bicycle parking within the individual units on the
second and third floor architectural plan sheets. Please revise the architectural sheets to show the location of the
dedicated space for long-term bicycle parking. Staff will support the storage area and storage units being permitted
for long-term bicycle parking.
6. Staff would like additional information on the management of the auto elevator prior to concurring with the location of
the auto elevator. Staff has concerns that the location and operations of the auto elevator will require waiting
vehicles to queue into the alley right-of-way and obstruct vehicle circulation within the alley. At time of site review
resubmittal please include a management for the auto elevator that addresses staff's concerns.
The applicant can expect additional comments from staff once this information is provided and reviewed by staff.
7. Please submit a parking management plans that: (i) includes a maintenance and repair plan for the auto elevator; (ii)
describes how funds will be set aside or collected for the maintenance and repair of the auto elevator; (iii) includes a
discussion for vehicles that can't be accommodated by the elevator and where those vehicles will park on the site
and (iv) details the necessary supporting equipment or cabinets and where the supporting equipment will be located
on the site.

III. INFORMATIONAL COMMENTS
1. Addressing, Sarah Shaffer, Address Administrator, 303-4137128, shaffers@bouldercolorado.gov
Each new building is required to be assigned a street address following the city’s addressing policy. However,
because the proposed building will be replacing an existing structure on the property, the current address of 1737
Pearl Street can me maintained for the new building.
2. Architectural Inspections, Sloane Walbert, 303-441-4231
The "rough and final architecture" inspection for buildings with discretionary approvals such as site and use
reviews will require that building architecture, materials and window details are consistent with approvals. The
inspection would occur as a part of the regular building permit inspection process.
3. Area Characteristics and Zoning History, Sloane Walbert, 303-441-4231
The site is located approximately 2.5 blocks east of the Pearl Street Mall. The properties consist of Lots 10 and 11,
Block 91 of the Boulder Original Town subdivision, originally platted in 1868. The properties were annexed to the
city in 1946. The property is not within a historic district but is located within the Central Area General Improvement
District (CAGID) and Downtown Boulder Business Improvement District (BID).
The site is within the Interface Area of Downtown Boulder and is subject to the Downtown Urban Design
Guidelines. The Interface Area is located on the northern, western, and eastern borders of Downtown. The
Interface Areas includes a wide variety of residential buildings. The area is composed of the blocks that link the
core of the Downtown to the surrounding residential neighborhoods. This area requires special design sensitivities
that must be addressed when commercial buildings are located adjacent to residential areas.
The property at 1727 Pearl St. contains 1 one-story structure and 1 two-story structure built ca. 1952. The buildings
contain retail and office uses. The property at 1737 Pearl St. contains a single-story structure built ca. 1966. The
original use was office; today the building contains retail (Red Letter Books) and restaurant (Strade Bianche) uses.
4. Drainage, Will Johnson, Johnsonw@Bouldercolorado.gov, 303-441-3273
A Final Storm Water Report and Plan will be required as part of the Technical Document Review process. All plans

7. Inclusionary Housing, Michelle Allen, 303-441-4076
a. Each new residential unit developed on the property is subject to 9-13 B.R.C., 1981, “Inclusionary Housing”
which requires is that all residential developments with 5 or more dwelling units contribute 25 percent (25%) of
the total dwelling units as permanently affordable housing affordable to low/moderate and middle-income
households. The means for satisfying the inclusionary requirement will be reviewed by staff concurrent with
any land use review or for those projects not subject to any land use review, prior to application for a
residential building permit.
b. Due to the small number of for-sale units, the entire development will be treated as rental for IH purposes.
Rental developments may satisfy the inclusionary requirement through the provision of on-site affordable
rental units or comparable existing or newly built off-site permanently affordable rental units or through the
dedication of land appropriate for affordable housing or by payment of a cash-in-lieu contribution.
c. A Unit and Cash-in-lieu Calculator for estimating the Inclusionary requirement for your development may be
found on the city website at www.boulderaffordablehomes.com.
d. Any applicable cash-in-lieu contribution must be made prior to receipt of a residential building permit.

Per Section 9-12-4, “Elimination of Lot Lines,” B.R.C. 1981 a lot line elimination plat is required to create one
buildable lot. A lot line elimination is a Techncial Document Review application, which should be submitted at the
tec. doc. review stage.
14. Review Process, Sloane Walbert, 303-441-4231
Per Table 2-2 of the land use code a concept plan and site review are not required for the project. However, the
proposal meets the thresholds for voluntary site review. A decision on this application (an approval, denial, or
approval with conditions) will be made by the Planning Department. Any decision by the Planning Department is
subject to call-up by the Planning Board within 14 days after a decision.
The property is subject to the Downtown Urban Design Guidelines and requires review by the Design Advisory
Board (DAB). DAB reviews and applies the guidelines on all projects with a construction value over $25,000 in the
Non-Historic and Interface Areas. The Planning Board applies these guidelines as part of the site review process.
15. Utilities, Will Johnson, Johnsonw@Bouldercolorado.gov, 303-441-3273
A Final Utility Connection Plan will be required as part of the Technical Document Review process (which must be
completed prior to building permit application). The Final Master Utility Plan (Utility Connection Plan) will be

The section below addresses issues that must be resolved prior to project approval.
Building Design
Sloane Walbert, 303-441-4231
Include a detail or indicate on the plans the proposed material at the feature wall in the courtyard. The elevation
shows CMU, but the renderings show stone or laminate cladding.
Drainage
Will Johnson, 303-441-3273
Mile High Flood District requires a minimum infiltration rate of 2 times the rate needed to drain the WQCV over 12
hours for full infiltration sections. Please update the drainage report to address this requirement for the proposed
porous pavers along the alley.
Agenda Item 5A Page 353 of 360
1737 PEARL ST Page 2 of 6
Landscape
Sloane Walbert, 303-441-4231
Staff does not agree with the modification to eliminate alley trees, which are intended to act as a buffer to the
residential zone district and activate the alley as a pedestrian space. The site review criteria state that:
“(iii) The project provides significant amounts of plant material sized in excess of the landscaping requirements of
Sections 9-9-12, "Landscaping and Screening Standards," and 9-9-13, "Streetscape Design Standards," B.R.C. 1981”
“(iv) The setbacks, yards and useable open space along public rights of way are landscaped to provide attractive
streetscapes, to enhance architectural features and to contribute to the development of an attractive site plan.”
Consideration needs to be given to reworking the side plan to accommodate alley trees, even if they are to be located
within the rain gardens.
Parking
David Thompson, 303-441-4417
1. Per staff's previous comment please revise the TDM Plan to state employees will have access to the residential
garage to access the bike locker and how access will be achieved.
2. This is a follow-up to staff's previous comment regarding the site's off-street delivery / loading area. Whereas staff
appreciates the design revisions that have been made to the loading area staff still doesn't concur with the proposed
length of the loading area given the frequency of delivery vehicles of a SU-40 design. To address this comment
please revise the site development plan to show the length of the off-street delivery / loading area at 40-feet. Staff
understands this comment will impact the proposed rain garden.
3. The applicant's draft parking management plan does not address staff's concerns regarding the frequency that
vehicles will queue in the public right-of-way (alley) due to conflicts with other vehicles either waiting or in the
process of entering or leaving the underground parking area. To address this comment the applicant needs to have
a consultant with experience in vehicle parking and auto elevators do an analysis which determines the frequency,
the number of vehicles and time of day when auto vehicles from the site will queue in the alley for staff's review
and comment. The analysis must consider the trip generation letter prepared by LSC, the type of residential land
use being proposed, the time it takes for the auto elevator to complete a cycle, if one auto elevator is sufficient for
the proposed land use and that 40-feet of off-street parking is available. The applicant can expect additional
comments on the queueing analysis and the parking management plan once the analysis is reviewed by staff. The
analysis must include recommendations on eliminating the potential of vehicle queueing in the alley. Staff is
available to discuss the scope of the analysis with the consultant prior to the consultant starting the work.
4. Per section 9-9-6(c)(1) B.R.C. 1981 with respect to rounding please revise Bicycle Parking Summary Chart to show
the required number of bicycle parking spaces for the retail use from "10" to "9" and revise the required number of
short-term bicycle parking spaces from "8" to "7". Revise the totals of the summary chart accordingly.
5. On Sheet SR-A1.01 - Please revise the sheet to remove the existing footnote (*) under the Bicycle Parking
Summary Chart because staff actually requested the short-term bicycle parking spaces be provided on the site.
Staff will support a footnote indicating where the inverted "u" bicycle racks will be installed in the Pearl Street
streetscape.
6. On Sheet SR-A2.B1 - Please revise the sheet to revise the label for the resident long-term bicycle parking spaces to
include their guest.
7. Please revise the project's TDM Plan to indicate the residential long-term bicycle parking area will be available for
residents and their guests.
8. Staff appreciates the applicant's willingness to install additional short-term bicycle racks along the Pearl Street
streetscape and will forward additional locations along Pearl Street where the applicant can install bike racks in
meeting to project's short-term bicycle parking requirements. Staff will forward this information to the applicant by
Friday, October 25th. Please ensure the project's TDM Plan is revised accordingly.

Sloane Walbert, 303-441-4231
1. Please add a note to the floor area analysis sheet stating that below grade floor area is not counted toward the total
floor area per Row 5 of Table 8-2, B.R.C. 1981.
2. Please add the proposed residential and commercial floor area to the land use summary table under floor area.
3. Please correct the site development plan to remove the bike racks erroneously shown adjacent to the northeast

III. INFORMATIONAL COMMENTS
1. Addressing, Sarah Shaffer, Address Administrator, 303-4137128, shaffers@bouldercolorado.gov
