Case number LUR2020-00019. Applicant: Ian Swallow, Boulder Housing Partners Property Owner: Housing Authority of the City of Boulder REQUESTING DEPARTMENT: Department of Planning & Development Services: Mary Ann Weideman, Interim Director Charles Ferro, Development Review Manager Shannon Moeller, Planner II OBJECTIVE: 1. Planning Board hears applicant and staff presentations. 2. Public Hearing. 3. Planning Board discussion and comment on concept plan. No action is required by Planning Board. PROPOSAL AND SITE SUMMARY: Proposal: CONCEPT PLAN REVIEW & COMMENT of a proposal to redevelop the property at 3485 Stanford Court to include 60 (56 one-bedroom, 4 two-bedroom) permanently affordable apartments for seniors (age 55+) and maintain the existing childcare facility on site. The original sanctuary building would be renovated to house the Rainbow Childcare Center and provide new community space for residents and potentially the broader community. The existing narthex building (constructed in 2001) would be demolished and new senior housing building to be placed on the western edge of the site. Project Name: MOUNT CALVARY SENIOR HOUSING Location: 3485 Stanford Court Size of Property: 4.9 acres Zoning: Residential - Medium 2 (RM-2) Comprehensive Plan: MR (Medium Density Residential) Agenda Item 5A Page 1 of 74 PROCESS The proposal is required to undergo a concept plan and site review because proposals over 2 acres or 20 dwelling units in the Residential - Medium 2 (RM-2) zoning district are required to complete a concept plan review and site review. The site review would amend the existing site review approval on the property. The purpose of the concept plan review is to determine the general development plan for a particular site and to help identify key issues in advance of a site review submittal. This step in the development process is intended to give the applicant an opportunity to solicit comments from the Planning Board as well as the public early in the development process as to whether a development concept is consistent with the requirements of the city as set forth in its adopted plans, ordinances, and policies (section 9-2-13, B.R.C. 1981). Concept plan review requires staff review and a public hearing before the Planning Board. BACKGROUND The 4.9-acre property is located in South Boulder at the terminus of Stanford Court, northwest of the intersection of Table Mesa Drive and South Broadway (refer to Figure 2 on the following page). The site contains two church structures, two large parking areas and community gardens. The northern portion of the site, which is heavily sloped, contains natural open space with social trails. The 14,590-square foot northern church structure (sanctuary) was constructed in 1957 and the approximately 14,667-square foot southern structure (narthex) was constructed in 2001. Refer to Figure 1 below. A breezeway connects the structures. The sanctuary structure is built into the slope as a one-story structure with a walk-out basement. The narthex is also built into the slope as a two-story building with a walk-out basement. Mount Calvary Lutheran Church operated on the property from 1957 until late 2019 when the congregation relocated. Community gardens are located on the western portion of the site. The far eastern arm of the property contains a formal pedestrian connection to Harvard Lane and South Broadway. I. INTRODUCTION AND BACKGROUND Figure 1: Birds-Eye View of Church Structures and Upper Parking Lot Agenda Item 5A Page 2 of 74 The property annexed to the city in 1958 with the three parcels at the far northeast corner per Ordinance No. 2095. At that time, the areas to the north and east were within the city limits. The property was zoned R-1 Residential zoning to conform with the adjacent properties. The property that currently contains the Table Mesa Shopping Center to the south and additional areas to the northwest of the property were annexed the same year. The late 1950s signified the beginning of the annexation and development of the South Boulder community west of Broadway. The area to the south of the property (Table Mesa Addition) was annexed and subdivided for residential development in 1961. The northwest corner of the site is split by right-of-way dedicated for the extension of 35th Street. The right-of-way was dedicated to the City of Boulder per a warranty deed in 1958. There are no plans to extend 35th Street and the applicant is anticipated to seek to vacate this right-of-way. A small portion of the driveway leading to the lower eastern parking lot is owned by the adjoining property (AIMCO's Boulder Creek Apartments); a perpetual easement was granted across this area in 2017. A Use Variance was approved in 1966 to permit the construction of seven multi-family units on the three parcels at the northwest corner of the property, mentioned above (now known as 499, 501, and 503 Harvard Lane). The property was owned by Mount Calvary Church at the time but was sold to a private developer. The property is part of the South Boulder Subcommunity. However, an area plan has not been adopted for this subcommunity. Refer to Guideline #1 below in Section III of this memo for additional information on the characteristics of the site and surrounding areas. History. The origins of the Mt. Calvary Lutheran Church can be traced to the early 1880s, when Swedish immigrants in Boulder established a congregation called the Bethesda Lutheran Church. The Bethesda Lutheran Church changed its name to the First Evangelical Lutheran Church of Boulder in 1930 and, later, to Mount Calvary Lutheran Church in 1955. The church acquired a six-acre site at 3485 Stanford Court (then addressed as 500 Princeton Court) in 1956. The original church structure was designed by Thomas E. Nixon, Jr. and Lincoln Jones and included seating for 220 and a basement that could be used for classrooms or a social hall. The building was dedicated on May 25, 1958. Refer to Figure 3 on the Figure 2: Vicinity Map Subject Property Dove r D r Agenda Item 5A Page 3 of 74 following page. The first of several additions to the building was added in 1961, an expansion of the basement to house additional classroom space. Another addition was made in 1964, this time an entire new wing to the south of the original church. In 2001, the current narthex structure replaced this wing south of the original church sanctuary. A significant interior remodel of the church was executed in 1978, and large bronze doors were installed on the main church in 1982. Land Use Designation. As shown in Figure 4 below, the site is currently designated as MR (Medium Density Residential) under the Boulder Valley Comprehensive Plan (BVCP) Land Use Map with a planned density of six to 14 units per acre. As part of the 2015 BVCP Update, the property was approved for a land use designation change from Low Density Residential (LR) to Medium Density Residential (MR). The five parcels south of the property (3255, 3305, 3355, 3405, 3455 Stanford Avenue) were also changed from LR to MR to be consistent with the existing RM-2 zoning and to provide the same designation as the properties to the south and east. Refer to Guideline #2 below for additional information on the land use designation change. Figure 4: BVCP Land Use Figure 3: Original Church c. 1965 Agenda Item 5A Page 4 of 74 Zoning. The project site is zoned Residential - Medium (RM-2), which is defined in subsection 9-5-2(c)(1)(B), B.R.C. 1981 as: “Medium density residential areas primarily used for small-lot residential development, including without limitation, duplexes, triplexes, or townhouses, where each unit generally has direct access at ground level” and which allows a maximum density of 12.4 dwelling units per acre. Refer to Figure 5 on the following page. The property was previously zoned RL-1, Residential – Low 1. It was rezoned as part of the implementation of the 2015 BVCP Update in 2017 by Ordinance 8208. Figure 5: Zoning Districts Previous Discretionary Reviews. A use exception was approved in 1965 to allow a nursery school in a single family residential zone district. Later, a special review was approved in 1973 (#SR-73-8) for a daycare center up to 40 students (the Boulder Montessori School). Subsequently, an additional daycare center was approved on the site in 1977 (#SR-77-17) for the Mount Calvary Rainbow Center. The use was limited to 15 students. The day care was permitted to expand to 25 students at the time that the Montessori School vacated the premises. The daycare was approved for hours of operation from 7:30 a.m. to 5:30 p.m. A conditional use review was granted for the religious assembly use per Site Review #SI-2000- 5. No expansion of the day care use was considered at that time. A Site Review (#SI-2000-5) was approved in 2000 for an addition to the church. The approval allowed for 29,257 square feet of floor area and permitted a height exception to 54 feet. Refer to Figure 6 on the following page. The request for an increase in building height was primarily due to the topography of the site. Following approval, the vehicular drive access to Harvard Lane was closed and a pedestrian connection was constructed. The city approved the location of wireless antenna on the site in 2001 to allow antenna inside the existing church cupola. A previous Concept Plan application (LUR2017-00031) was submitted in 2017 and withdrawn prior to a Planning Board hearing. That prior proposal included 45 permanently affordable senior residential units and to maintain the existing church and daycare uses on the site. Ownership. Housing Authority of the City of Boulder (Boulder Housing Partners) owns the property. It was previously owned by the Mount Calvary Lutheran Church and Frasier Meadows. All units are expected to be permanently affordable. RL-1 RM-2 BC-2 Agenda Item 5A Page 5 of 74 Figure 6: Church Addition Constructed in 2001 Land Uses. The proposal includes the following uses: • Residential: 60 permanently affordable residential units available to seniors (age 55 and over) earning less than 60 percent of the Area Median Income. The residential development would be multi-family stacked flats in one building. The units would be rentals managed by Boulder Housing Partners. The total unit mix would be 56 one-bedroom and 4 two-bedroom units. The development is not intended for congregate care or assisted living. • Day Care. The existing Rainbow Daycare use would continue to operate. Site Plan. The proposal is to demolish the addition constructed in 2001, maintain the original sanctuary building constructed in 1957, and construct a new three-story residential building on the southwestern portion of site not impacted by steep slopes. The lower eastern parking area is proposed to remain with some improvements. A drive access is proposed along the south property line to provide access to a smaller western parking area and the western portion of the building. The applicant has received input from the surrounding community that maintaining the sweep of the existing ridge and character of the hillside is important and the proposal seeks to maintain this hillside intact. The north portion of the site is proposed to remain natural open space. Refer to Figure 7 below. Architecture and Building Design. The Concept Plan proposes a contemporary building with stacked flats on a double loaded corridor. The structure is cut into the grade, appearing primarily as a three-story structure toward the eastern end and a two-story structure at the western end. The building is primarily oriented parallel to the southern property line, with two short “wings” extending northward at the western end of the building, and extending northeast at the eastern end of the building toward the existing sanctuary building. Several outdoor spaces are provided, including the large patio north of the building offering expansive views, outdoor terraces on upper levels, and small private outdoor spaces for garden- and ground-level dwelling units. A covered vehicle drop-off is provided at the southern entry. Refer to Guideline #3 below in Section III of this memo for staff’s initial review comments on the building and site design. II. Project Description Agenda Item 5A Page 6 of 74 Figure 7: Site Plan 1st Floor Site Plan 2nd Floor Site Plan Agenda Item 5A Page 7 of 74 Open Space Areas. As described above, proposed open space for the development consists of passive natural open space on the hillside, a large patio north of the building offering expansive views, outdoor terraces on upper levels, and small private outdoor spaces for garden- and ground-level dwelling units. Community garden plots are proposed at the western extent of the site. Indoor community space will also be provided at the ground floor and in the existing sanctuary building. The existing paved path on the east end of the site that connects to Harvard Lane, would also remain. Access and Parking. The development will continue to be accessed from Stanford Court. 73 parking spaces are proposed total in the west and east parking areas. 62 parking spaces are required for the proposed 56 one-bedroom units and 4 two-bedroom units. Required parking for the daycare center is determined through review per Table 9-4, B.R.C. 1981. Additional information will be required at site review to determine the required number of spaces. The applicant submitted a preliminary traffic study prepared for the project, which provides a trip generation estimate of 12 vehicle trips during the A.M. peak hour and 16 vehicle trips during the peak hour for the senior housing use. Refer to Attachment A. Bicycle parking for the proposed housing is required per 9-9-6(g) “Bicycle Parking,” B.R.C. 1981 as 30 short-term spaces and 90 long-term spaces. Like vehicular parking, bicycle parking for daycare uses is determined through review. Additional information will be required at site review to determine that adequate and appropriate bicycle parking is provided. Figure 10: Social Footpath on Hillside Figure 8: North Elevation Figure 9: South Elevation Agenda Item 5A Page 8 of 74 Guidelines for Review and Comment: The following guidelines will be used to guide the Planning Board's discussion regarding the site. It is anticipated that issues other than those listed in this section will be identified as part of the concept plan review and comment process. The Planning Board may consider the following guidelines when providing comments on a concept plan: 1) Characteristics of the site and surrounding areas, including, without limitation, its location, surrounding neighborhoods, development and architecture, any known natural features of the site including, without limitation, mature trees, watercourses, hills, depressions, steep slopes, and prominent views to and from the site; Natural Features. The existing topography limits the development potential of the site. The site is relatively level (4 percent slope) on the southwestern quadrant, which then steeply drops off a ridge to the north and east. The high point on the site is in the far southwest corner and the low point is on Harvard Lane. The northwest corner of the property is within the "Potential Mass Movement Hazard" area of the BVCP Geological Development Constraints Map (Pendleton Map). The Anderson Ditch runs adjacent to the northern edge of the site and the far eastern portion of the property is impacted by the 500-year floodplain for Bear Creek. There are prominent and grand views to the west, north and east from the site, which include the Flatirons, cityscape, and foothills (see Figures 11 and 12). Refer to criterion 6 below for further analysis on environmental opportunities and constraints. Surrounding Neighborhood. The immediate context is characterized by residential development at a range of densities. The five properties to the southwest of the property contain duplex structures built in the 1970s. To the south and southeast are large multi-family developments, the Boulder Creek Apartments and the Harvard Park Apartments. At the northeast corner of the property on Harvard Lane are three multi-family structures built in the late 1960s, mentioned above under Background. III. Concept Plan Review Criteria for Planning Section 9-2-13(g) Figure 11: Views to the North Figure 12: Views to the West Agenda Item 5A Page 9 of 74 The area to the east and north is characterized by single-family residences within the Highland Park and Table Mesa subdivisions. The development pattern and residential architecture within these neighborhoods is representative of post- WWII residential neighborhoods in Boulder. Refer to Key Issue #2 in Section IV of this memo for additional information on the character of the surrounding area. Surrounding Uses. Various services and amenities are located within a short walking distance of the site. The George Reynolds Branch Library is located less than a ¼ mile to the south, at the intersection of Stanford Avenue and Table Mesa Drive. A large commercial center, the majority of which is the Table Mesa Shopping Center, is located directly to the south across Table Mesa Drive. The center contains a grocery store, restaurants, pharmacies, banks, retail shops, dental offices, and service uses like auto repair, dry cleaners, salons, etc. The shopping center is accessible via a pedestrian crossing and light just west of Stanford Avenue. Medical and dental offices are located to the west of the Table Mesa Shopping Center at the Bear Creek Offices (3400 Table Mesa Drive). Boulder Mennonite Church and St. Martin De Porres Catholic Church are located within ½ mile on Table Mesa Drive. Across Broadway, to the east, is Martin Park. The park is easily accessible via a pedestrian underpass and contains recreational amenities including tennis courts, baseball diamond, and a playground. Figure 14: Surrounding Uses South Boulder Recreation Center, Fairview High School, Harlow Platts Community Park, and Viele Lake are an approximately one mile walk to the south or accessible via the SKIP transit line. ½ MILE RADIUS Figure 13: View of Church from Dover Drive Martin Neighborhood Park Table Mesa Shopping Center George Reynolds Branch Library Bear Creek Offices Agenda Item 5A Page 10 of 74 2) Community policy considerations including, without limitation, the review process and likely conformity of the proposed development with the Boulder Valley Comprehensive Plan and other ordinances, goals, policies, and plans, including, without limitation, subcommunity and subarea plans; The property is not within a subarea plan. As part of the 2015 Boulder Valley Comprehensive Plan (BVCP) update a Land Use Change Request was processed to change the land use designation from Low Density Residential (LR) to Medium Density Residential (MR) on the BVCP land use map. As described above, the five parcels to the south were also changed from LR to MR. The request was approved by Planning Board (Oct. 13) and City Council (Nov. 1) for the following reasons: • Diversity of housing types and price ranges is a core value of the Comprehensive Plan, recognizing that the availability of housing affordable to both low- and moderate-income populations is “a growing concern”. • There is a scarcity of sites for housing in Boulder Valley. Allowing Medium Density Residential will increase the diversity of housing types. • The Medium Density Residential designation furthers other key BVCP policies, including jobs:housing balance, and strengthening community housing partnerships. • The designation is consistent with the mix of residential densities to the south and could be compatible with the single-family residential neighborhoods to the north and west through good site planning. • The location and characteristics of the site make it suitable for new residential development on the upper portions of the site that are not on a steep slope. Refer to the staff memo for the joint meeting of City Council and Planning Board on Oct. 13, 2016 for additional information. In addition, Policy 2.27 of the BVCP states: “The city and county will identify, evaluate and protect buildings, structures, objects, districts, sites and natural features of historic, architectural, archaeological or cultural significance with input from the community. The city and county will seek protection of significant historic and cultural resources through local designation when a proposal by the private sector is subject to discretionary development review.” As such, staff will evaluate landmarking the 1957 church structure at time of site review. Refer to Guideline #8 below for staff’s analysis regarding the proposal’s compliance with housing policies. Refer to Key Issue #2 for a preliminary analysis with BVCP policies. 3) Applicable criteria, review procedures, and submission requirements for a site review; The proposal would require a site review application and upon submittal, would be evaluated for conformance with the following: • The land use designation in the BVCP; • All relevant policies of the BVCP; • The site review criteria of the Land Use Code; • Zoning regulations; • The criteria of Section 9-9-11 of the land use code for usable open space. • The City of Boulder Design and Construction Standards (DCS). The proposal may require a modification to section 9-7-1 of the land use code to allow the height of the structure to Agenda Item 5A Page 11 of 74 exceed 35 feet due to the topography of the site and if roof forms are revised to include pitched roofs. In 2015, City Council approved a height ordinance in which modifications to the by-right height for new buildings will only be considered through the site review process in specific parts of the city or in particular circumstances. This proposal would be eligible for a height modification because at least forty percent of the floor area of the proposed building is for units that meet the requirements for permanently affordable units in Chapter 9-13, "Inclusionary Housing," B.R.C. 1981. Planning Board action is required for site reviews which include the height modifications. If a height modification is requested, a decision on the application would be made at a public hearing before Planning Board. Special consideration will be given to the following site review criteria: • Design and location of open spaces. “Useable open space is arranged to be accessible and functional and incorporates quality landscaping, a mixture of sun and shade and places to gather” (criterion (h)(2)(A)(i)). Staff appreciates the incorporation of multiple types and locations of proposed open space, including the large ground level patio, private patios for garden-level and ground-level units, upper floor outdoor spaces, and community gardening. Staff recommends further refinements to open spaces and landscape buffers to ensure adequate buffering from properties to the west and south, from the proposed southern drive aisle to adjacent garden-level units, and organization and access to the community gardening area. • Design of vehicular and pedestrian access on the site. “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” (criterion (h)(2)(D)(iii). Consideration should be given to providing a sidewalk connecting the site buildings to the existing sidewalk on the east side of Stanford Court that is physically detached from the drive aisle/parking lot and a pedestrian connection between the site buildings and the existing pedestrian path on the east end of the site. The applicant should also explore the implementation of traffic calming designs such as curb extensions or raised crosswalks to reduce the speeds of vehicles in the parking lot area. • Design of the buildings to ensure that 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” (criterion (h)(2)(F)(i)). Staff appreciates elements of the site planning including preservation and adaptive reuse of the existing church, programming passive and active open space areas and the connection of the path to the northwest. Staff encourages the applicant to consider adjustments to the proposed building massing and the solar exposure to the primary outdoor space on the north of the building, adjustments to the primary entry feature of the residential units to be more visible and architecturally legible, and consider how HVAC and other rooftop mechanical systems and the associated screening will be addressed. • Appropriate building height. “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” (criterion (h)(2)(F)(ii)). If a height modification is requested, staff encourages provision of a massing model taken in isometric perspective, showing the portion of the proposed addition that extends above the maximum height, and the building’s relationship to its surroundings. • Utilization of a palate of simple, high-quality building materials. “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” (criterion (h)(2)(F)(xii)). Staff appreciates the deliberate bay organization of the residential units and the associated hierarchy of the window families and material assignment. In addition, there is an interesting interplay between smooth and textured surfaces implied in the early sketch elevations. At the time of Agenda Item 5A Page 12 of 74 site review, staff will request more information regarding the materiality, construction and durability to meet site review criteria. • Sustainability. “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” (criterion (h)(2)(F)(xi)). Staff recommends passive sustainability elements that may augment the building energy performance and design, e.g. solar shading devices on the south and/or west facing facades with large percentages of glazing. • Preservation of existing contours and slope. “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” (criterion (h)(2)(F)(xiii)). Staff is supportive of the proposal to preserve the aesthetic and environmental character of the hillside. At the time of site review, the following items will be required: a. Transportation Demand Management (TDM) Plan, which outlines strategies to mitigate traffic and parking impacts created by the proposed development and implementable measures for promoting alternate modes of travel. b. A detailed tree inventory including the species, size, and condition of all existing trees on the site. Staff encourages the preservation of any healthy, sizable trees possible on the site. c. Landscape plan that is consistent with, and exceeds, city code requirements. While minimum overall site landscaping is not required in the RM zone, staff encourages meeting the standard for other zoning districts in subsection 9-9-12(d)(8), B.R.C. 1981 to demonstrate compliance with applicable landscape site review criteria. Planting should be intentional and integrated into the private units and public gathering spaces to serve both the residents, daycare, and community as appropriate. d. If a height modification is requested, a list of the height of each principal building located or known to be proposed or approved within one hundred feet of the proposed project and a written statement and drawings which describes the way in which the proposal accommodates pedestrians, including without limitation uses proposed for the ground level, percent of transparent material at the ground level, and signage and graphics per 9-2-14(e) “Additional Application Requirements for Height Modification,” B.R.C. 1981. Consideration should be given to providing a massing model taken in isometric perspective, showing the portion of the proposed addition that extends above the maximum height. e. In support of the design excellence initiative, additional information will be required at site review on the building materials and building assembly to ensure high-quality design outcomes. f. A preliminary stormwater report and plan to address stormwater runoff and water quality treatment issues. Because impervious area on the site will be increased, detention/water quality facilities will be required since runoff for the initial and major storm events cannot be conveyed directly to a major drainage way. g. The applicant is responsible for obtaining approvals for any relocations or modifications to irrigation ditches or laterals from the impacted ditch company prior to site review approval or hearing. h. A water system distribution analysis (Utility Report) in order to assess the impacts and service demands of the proposed development. Conformance with the city’s Treated Water Master Plan (October 2011) is necessary. i. A wastewater collection system analysis (Utility Report) will be required at time of Site Review to determine any system impacts based on the proposed demands of the development. The analysis will need to show conformance with the city’s Wastewater Collection System Master Plan, July 2016.A utility plan and utility Agenda Item 5A Page 13 of 74 connection plan. j. A utility plan and utility connection plan. On-site and off-site water main and wastewater main construction per the City of Boulder Design and Construction Standards (DCS) as necessary to serve the development. 4) Permits that may need to be obtained and processes that may need to be completed prior to, concurrent with, or subsequent to site review approval; Use Review. The existing daycare center would be permitted to continue in operation with the same operational characteristics (section 9-1-4(e), B.R.C. 1981). Any change or expansion of the daycare use would be reviewed per the use review criteria in section 9-2-15, B.R.C. 1981. TABLE 1 Proposed Use RM-2 Zoning Attached dwellings Allowed Daycare centers Use Review Right-of-Way Vacation. If necessary, the applicant will be required to submit a separate application to vacate the right-of- way dedicated for 35th Street. Easements may be necessary to accommodate utilities or pedestrian/bike connections within the right-of-way area, which will be evaluated by staff as the project proceeds site review. Per section 43-2-303 of the Colorado Revised Statutes (C.R.S.), “roadways” must be vacated by ordinance with City Council approval. Roadways are defined as "any platted or designated public street, alley, lane, parkway, avenue, road, or other public way". Ordinances require a first and second reading before City Council. Historic Preservation. If landmarking the 1957 structure is desired by the city and/or applicant an application for an Individual Landmark would be necessary. Technical Documents. Following site review, technical documents would be submitted and evaluated for final utilities, drainage, transportation, architecture, and landscaping. Subdivision. The property is currently an unplatted tract of land and contains a parcel of land conveyed by the property owner to the south. Staff recommends completing a subdivision (preliminary and final plat) as part of the development proposal. Any necessary vacations of easements and dedications of easements and right-of- way could be done on the final plat. Building Permit. Once site conditions were found to be compliant with all applicable codes, a building permit for any new structures or site work could be reviewed. Additional submittal requirements at the time of building permit application may be necessary to ensure compliance with the City of Boulder Steep Slope Ordinance and Hillside Development Guidelines, which apply to lands containing slopes of fifteen percent or greater. This includes a soils report and a grading/drainage plan prepared by a Colorado licensed, professional engineer. 5) Opportunities and constraints in relation to the transportation system, including, without limitation, access, linkage, signalization, signage, and circulation, existing transportation system capacity problems serving the requirements of the transportation master plan, possible trail links, and the possible need for a traffic or transportation study; Agenda Item 5A Page 14 of 74 Based on analysis done as part of the 2015 BVCP update, the weighted access score for the property was the highest possible (70-86 percent accessible), determined by a combination of the availability of transportation facilities and the number of destinations that can be reached within a 15-minute walk. Access: Access to the site is from Stanford Court and Stanford Avenue, both of which are classified as local streets. Table Mesa Drive is classified as an arterial. No changes are proposed to the existing access point. Due to the topography city staff would not support vehicular access from Dover Drive or Harvard Lane. A curb cut existed on Harvard Lane, which provided direct access to the site, prior to 1966. The curb cut was removed when the church was expanded in 2001 and it has now been replaced with a sidewalk and drainage chase. Refer to Figure 15. Transit: The site is well served by public transit. The is site located on two major transit corridors, Table Mesa Drive and Broadway. Several bus stops are located approximately a quarter mile away on Table Mesa and on Broadway. Local and regional routes operate on Broadway, including the SKIP, DASH, FF1, FF5, AB1, and GS, including providing travel to Denver International Airport and the Denver metro area. In addition, the SKIP line provides frequent service to downtown, the University of Colorado, and north and south Boulder. Connections: The site is well connected for bicyclists and pedestrians. Several multi-use paths, on-street bike lanes, and designated bike routes provide access east-west and north-south from the site. A sidewalk, which contains some stairs, is located on the east end of the property to connect the development to Harvard Lane and Broadway. Refer to Figure 18 above. Currently, social paths connect the site with the residential development to the north. An attached sidewalk exists along the east side of Stanford Court, connecting Stanford Avenue to the site. A pedestrian crossing exists at Stanford Avenue and Table Mesa Drive to allow crossing to the Table Mesa Shopping Center. Staff has requested a sidewalk connecting the site buildings to the existing sidewalk on the east side of Stanford Court from the drive aisle/parking lot and a pedestrian connection between the site buildings and the existing pedestrian path on the east end of the site. An underpass at Table Mesa and Broadway allows pedestrians and bicyclists safe and convenient access under Broadway. Aside from a portion that is a designated bike lane on Harvard Lane, multi-use paths provide convenient access north-south on Broadway. Bike lanes are provided on Table Mesa Drive to the west, which provide access to the National Center for Atmospheric Research (NCAR) and Lehigh Street. Multi-use paths are provided along Table Mesa Drive to the east, which connect to the U.S. 36 regional bike route. Traffic Study: The preliminary traffic study submitted by the applicant estimates that the proposal would generate 222 new daily vehicle-trips. The study estimates that four vehicles would enter and eight vehicles would exit the site during the morning peak-hour (12 total) and ten vehicles would enter and six vehicles would exit the site during the afternoon peak-hour (16 total) (refer to Attachment A). Per the City’s Design and Construction Standards, a traffic study is not required for the project because the trips generated by the site improvements during the AM or PM peak hour is less than the threshold requirement of 20 vehicle trips. The Applicant will be required to submit a Transportation Demand Management (TDM) Plan at the site review stage. Parking: 73 motor vehicle parking spaces are proposed total in the west and east parking areas. 62 parking spaces are Figure 15: Pedestrian Connection to Harvard Lane Agenda Item 5A Page 15 of 74 required for the proposed 56 one-bedroom units and 4 two-bedroom units and required parking for the daycare center is determined through review per Table 9-4, B.R.C. 1981. Additional information will be required at site review to determine the required number of spaces since parking for daycare uses is determined through review. The parking needs of employees, volunteers, and visitors must be adequately served. Bicycle parking for the proposed housing is required per 9-9-6(g) “Bicycle Parking,” B.R.C. 1981 as 30 short-term spaces and 90 long-term spaces. Like vehicular parking, bicycle parking for daycare uses is determined through review. Additional information will be required at site review to determine that adequate and appropriate bicycle parking is provided. The Applicant will be required to submit a Transportation Demand Management (TDM) Plan at the site review stage. 6) Environmental opportunities and constraints including, without limitation, the identification of wetlands, important view corridors, floodplains and other natural hazards, wildlife corridors, endangered and protected species and habitats, the need for further biological inventories of the site and at what point in the process the information will be necessary; Refer to Guideline #1 above for the natural features of the site. The far eastern portion of the property is impacted by the 500-year floodplain for Bear Creek. The property is not impacted by wetlands and is located outside of the wildland urban interface. There does not appear to be wildlife corridors or the presence of endangered or protected species/habitats. There is a variety of tree species and several healthy, sizable trees on the site, which should be preserved to the extent possible. The character of the hillside, which is heavily vegetated, should also be preserved. View corridors from the bottom of the hill towards the Flatirons should be preserved to the extent possible. Figure 16: Natural Hillside 7) Appropriate ranges of land uses; A residential use of the property is appropriate given the surrounding context. Refer to Section V “Key Issues” below for additional analysis. Agenda Item 5A Page 16 of 74 8) The appropriateness of or necessity for housing. Diversity of housing types and costs is a core value of the Comprehensive Plan, recognizing that the availability of housing affordable to both low- and moderate-income populations is “a growing concern”. This issue was identified in the 2015 Boulder Valley Comprehensive Plan Survey as the number one community value in greatest need of increased attention by 42 percent of the respondents. As part of the survey, respondents identified more affordable housing units as a top priority for neighborhood improvements (17 percent). Forty-six percent of respondents within the South Boulder Subcommunity valued more affordable housing units as part of the survey. The proposal calls for 60 (56 one-bedroom, 4 two-bedroom) apartments which would be 100 percent permanently affordable and age restricted for seniors. Section V “Key Issues” below addresses the extent to which the project addresses housing-related BVCP policies and other city housing policies. Key Issue #1: Is the proposed concept plan compatible with the goals, objectives, and recommendations of the Boulder Valley Comprehensive Plan (BVCP)? Staff finds that the concept plan is consistent with the goals, objectives, and recommendations of the BVCP. In general, the project supports opportunities for much needed senior affordable housing and is generally consistent with established neighborhood character. The current proposal appears to be consistent with the following BVCP goals and policies: BVCP Policy Excerpt from BVCP How the Proposal is Consistent with BVCP Policies Neighborhoods 2.10 Preservation and Support for Residential Neighborhoods “…protect and enhance neighborhood character and livability…” The consistency of the proposal with existing neighborhood character is addressed in Key Issue #4 below. 2.14 Mix of Complementary Land Uses “(…) city and county will strongly encourage, consistent with other land use policies, a variety of land uses in new developments. In existing neighborhoods, a mix of land use types, housing sizes and lot sizes may be possible if properly mitigated and respectful of neighborhood character. (…)” IV. KEY ISSUES ANALYSIS Agenda Item 5A Page 17 of 74 BVCP Policy Excerpt from BVCP How the Proposal is Consistent with BVCP Policies Neighborhoods 2.15 Compatibility of Adjacent Land Uses “To avoid or minimize noise and visual conflicts between adjacent land uses that vary widely in use, intensity or other characteristics, the city will use tools such as interface zones, transitional areas, site and building design and cascading gradients of density in the design of subareas and zoning districts. With redevelopment, the transitional area should be within the zone of more intense use.” A drive lane and parking area are proposed to the west and south of the new building to serve as a buffer between the proposed dwelling units and the adjacent low- and medium- density housing. Staff recommends providing a landscape buffer in this area to sensitively transition to surrounding development. The site plan also provides a buffer to the single-family homes to the north by maintaining the natural hillside. Mixed-Use & Higher Density Development 2.16 Mixed Use and Higher Density Development “The city will encourage well-designed mixed use and higher density development that incorporates a substantial amount of affordable housing in appropriate locations, including in some commercial centers and industrial areas and in proximity to multimodal corridors and transit centers.” The proposal consists of a mixed-use development with attached housing and daycare uses. The housing is proposed to be permanently affordable housing. The development is situated near Table Mesa Drive and Broadway, both major multimodal corridors. Support Community Housing Needs 7.01 Local Solutions to Affordable Housing 7.02 Permanently Affordable Housing “(..) The city and county recognize that affordable housing provides a significant community benefit …” “The city will study and consider substantially increasing the proportion of housing units permanently affordable to low-, moderate- and middle-income households beyond our current goal of at least ten percent of the housing stock for low and moderate incomes…” The proposal for 60 permanently affordable housing units supports these BVCP policies. Agenda Item 5A Page 18 of 74 BVCP Policy Excerpt from BVCP How the Proposal is Consistent with BVCP Policies Preserve & Enhance Housing Choices 7.06 Mixture of Housing Types 7.09 Housing for a Full Range of Households “The city and county, through their land use regulations and housing policies, will encourage the private sector to provide and maintain a mixture of housing types with varied prices, sizes and densities to meet the housing needs of the low-, moderate- and middle-income households of the Boulder Valley population.” “The city and county will encourage preservation and development of housing attractive to current and future households, persons at all stages of life and to a variety of household configurations. This includes singles, couples, families with children and other dependents, extended families, non- traditional households and seniors.” The proposal helps to meet the housing needs of the Boulder Valley population through the provision of much-needed affordable senior housing that will help improve the diversity of permanently affordable housing types. Community Identity & Land Use Pattern 2.03 Compact Development Pattern “The city and county will, by implementing the comprehensive plan (as guided by the Land Use Designation Map and Planning Areas I, II, III Map), ensure that development will take place in an orderly fashion, take advantage of existing urban services, and avoid, insofar as possible, patterns of leapfrog, noncontiguous, scattered development within the Boulder Valley. The city prefers redevelopment and infill as compared to development in an expanded Service Area to prevent urban sprawl and create a compact community.” The infill of housing on this property supports a compact development pattern. Public Realm, Urban Design & Linkages 2.24 Commitment to a Walkable and Accessible City “The city and county will promote the development of a walkable and accessible city by designing neighborhoods and business areas to provide easy and safe access by foot to places such as neighborhood centers, community facilities, transit stops or centers, and shared public spaces and amenities. (...)” The proposal is within walking distance (1/4 mi.) of transit, a public library, and amenities at the Table Mesa Shopping Center, including a grocery store, pharmacy, bank, and restaurants, among others. Design Quality 2.41 Enhanced Design for All Projects “i. On-site open spaces. Projects should incorporate well-designed functional open spaces with quality landscaping, access to sunlight and places to sit comfortably. Where public parks or open spaces are not within close proximity, shared open spaces for a variety of activities should also be provided within developments.” The site plan illustrates a variety of open spaces including pathways, outdoor patios at ground level and on upper floors, and community gardens with the intent to serve as functional, shared open spaces. Agenda Item 5A Page 19 of 74 BVCP Policy Excerpt from BVCP How the Proposal is Consistent with BVCP Policies Social Equity 8.05 Diversity “…support inclusion of racial, ethnic, socioeconomic, and cultural diversity into physical, social, cultural and economic environments …” The provision of permanently affordable, senior housing units will help support socioeconomic diversity. The current proposal could use improvement in terms of consistency with the following BVCP goals and policies: BVCP Policy Excerpt from BVCP How the Proposal is Inconsistent with BVCP Policies Design Quality 2.41 Enhanced Design for All Projects “e. Transportation connections. Projects should provide a complete network of vehicular, bicycle and pedestrian connections both internal to the project and connecting to adjacent properties, streets and paths, including dedication of public rights-of-way and easements where required. Additional information should be provided at the time of site review do demonstrate clear pedestrian connections throughout the site, to Stanford Court, and through the parking area to Harvard Lane. Key Issue #2: Would the project be compatible with the character of the surrounding area? Are the architectural and site design consistent with the site review criteria in terms of quality and compatibility with the surrounding neighborhood? Redevelopment projects should become a coherent part of the neighborhood in which they are placed (see Policy 2.41(b) Enhanced Design for All Projects). As described above, several BVCP policies address the protection of and compatibility with established residential neighborhoods. Among these is Policy 2.10 Preservation and Support for Residential Neighborhoods, which encourages working collaboratively with neighborhoods. BHP describes its process of working with neighbors in the “Engagement” section of its proposal. In addition, the following is among the site review criteria: “the building height, mass, scale, orientation, architecture and configuration are compatible with the existing character of the area” (section 9-2-14(h)(2)(F)(i), B.R.C. 1981). For the purposes of determining compatibility, staff has analyzed character, density, mass and scale, and site layout below. Character. Per the analysis under Guideline 1 above, the surrounding area is characterized by residential development at a range of densities. The development represents a diversity of housing forms and architectural types. The area to the east and north is characterized by single-family residences within the Highland Park and Table Mesa subdivisions. The five properties to the southwest of the property contain duplex structures built in the 1970s. To the south and southeast are large multi-family developments, the Boulder Creek Apartments and the Harvard Park Apartments. At the northeast corner of the property on Harvard Lane are three multi-family structures built in the late 1960s. Refer to Figure 17 on the following page. Agenda Item 5A Page 20 of 74 Figure 17: Surrounding Developments The Highland Park neighborhood to the north and east (Fifth and Seventh Additions) is indicative of a post-WWII subdivision. The development consists of modest homes on varying lot sizes with curvilinear roads. A majority of the homes were constructed in the 1950s or early 1960s. The lots are shallow with front-accessed driveways in the front yard. Homes constructed in the 1950s are predominantly low, one-story ranch house types, while homes constructed in the 1960s include split-level and bi-level houses in a range of stylistic variations. Most homes have low-pitched hipped or gabled roof forms. Building materials are predominantly brick and wood siding. Refer to Figures 18, 19, 20, and 21. Figure 18: Split Level Home, Fifth Addition to Highland Park Figure 19: Ranch Style Home, Fifth Addition to Highland Park Fifth Addition to Highland Park (Platted 1956) Outlot B and D of Table Mesa Addition (Platted 1962) Seventh Addition to Highland Park (Platted 1959) Table Mesa First Addition (Platted 1962) Annexed with Subject Property (Annexed 1958) Single Family in Table Mesa Addition (Platted 1962) Outlot C of Table Mesa Addition (Platted 1962) Agenda Item 5A Page 21 of 74 Figure 20: Ranch Style Home, Seventh Addition to Highland Park The residential development to the south was annexed to the city in 1959 and was latter platted as Table Mesa Addition in 1962. The development within Table Mesa subdivision is indicative of a large-scale, late-postwar subdivision with broad, curvilinear streets and cul-de-sacs. The single-family homes within Table Mesa to the south and west consist of larger homes than Highland Park, with ranch, bi-level, split-level, and two-story houses. These homes were primarily constructed in the 1960s and feature low-pitched roofs and a wider variety of architectural details. Building materials are predominantly brick and wood siding. Refer to Figure 22. The five duplex structures adjacent to the subject property to the south were built in the 1960s and 70s within Outlot C of Table Mesa Addition. The duplexes are two stories with low-pitched hipped or gabled roof forms and feature stone and wood siding. Refer to Figure 23. Adjacent to the site to the southeast is a multi-family development (Boulder Creek Apartments), which was developed within Outlot B and D of the same subdivision. The development was approved as a Planned Unit Development in 1970 and was revised in 1972. The development contains two-story townhome- style apartments, one-story detached garage structures, and community buildings. The buildings have gabled roofs and are primarily stucco, with stone accents. Refer to Figure 24 on the following page. At the far southeastern corner of the subject property is the small multi-family development (Harvard Park Apartments), which was built in 1964. The development contains two-story apartment style buildings with detached garage structures around surface parking, with limited landscaping or open space. The buildings have pitched roofs and are clad with brick with wood siding. Refer to Figure 25 on the following page. Figure 21: Split Level Home, Seventh Addition to Highland Park Figure 22: Split Level Home, Table Mesa Addition Figure 23: Duplex, Outlot C of Table Mesa Addition Agenda Item 5A Page 22 of 74 Figure 24: Boulder Creek Apartments Figure 25: Harvard Park Apartments At the far northeast corner of the property on Harvard Lane are three multi-family structures on three parcels, which contain seven apartment units. The development was approved as a Use Variance in 1966 and was built in 1969. Consistent with the surrounding 1960s development, the three buildings have pitched roofs and feature brick and board and batten wood siding. Refer to Figure 26. Staff finds that the proposed contemporary design is generally compatible with the surrounding development and church structures. However, consideration should be given to a design that is sensitive to the character of the historic church. The site plan and building must integrate with, and relate to the modern design of the church. The building could introduce new contemporary design while taking cues from the historic structure, like building materials, colors, etc. Density: The surrounding area represents a mix of residential densities including attached and detached dwelling units. The proposal is consistent with the range of surrounding densities, with the BVCP Land Use Designation of Medium Density Figure 26: 503 Harvard Lane Agenda Item 5A Page 23 of 74 Residential, which permits densities of 6 to 14 dwelling units per acre, and with the underlying zoning which permits densities of up to 12.4 dwelling units per acre. Refer to Table 2 for a summary of surrounding densities. TABLE 2 Development Estimated Density (Dwelling Units Per Acre)* Proposal 12.2 South Duplexes - Outlot C of Table Mesa Addition 9.1 South Multi-Family - Outlot B and D of Table Mesa Addition 18.9** Northeast Multi-Family – Parcels Annexed with Mt.

Calculations reflect select sum of select subdivision’s area that includes lots with housing units. Common area/shared ownership lots without housing units and rights of way were excluded from the calculations. Subdivision boundaries based on city’s GIS database. It is important to note that densities described in the BVCP for residential land use designations are gross density, including rights-of-way. ** Additional development potential exists at the Boulder Creek Apartments that, if constructed, would result in 19.6 du/acre. *** Table Mesa First Addition is a large subdivision. Only portions of the subdivision directly to the southwest of the subject property were analyzed. Mass and Scale. Building mass and scale appear to be appropriate with the established character of the neighborhoods surrounding the site. The majority of the surrounding structures are two stories in height. However, the building is proposed to be built into the hillside so that the structure will transition from three stories to two stories, where the development pattern transitions to single family development to the west. Additionally, care has been taken to reduce the perceived bulk and massing of the building by incorporating outdoor open spaces at the upper levels of the building at key locations. Site Layout. The site layout is guided by the desire to preserve the existing natural hillside and maintain the original church sanctuary built in 1957. The proposal removes the existing church addition built in 2001 and incorporates the proposed residential building into the southwest area of the site. As described in the applicant’s written statement (Attachment A), the proposed site layout was selected after receiving input from the surrounding community on multiple options. Staff recommends further refinements to open spaces and landscape buffers to ensure adequate buffering from properties to the west and south. Based on the analysis above, staff finds that the proposal is generally compatible with the character of the area and the site review criteria in terms of character, density, scale, massing, and design. Some refinements are necessary to building and site design to provide an appropriate buffer to adjacent residential uses, better communicate the residential use, and to integrate the development with the church structure. Required public notice was given in the form of written notification mailed to all property owners within 600 feet of the subject site. The requirement for sign posting found in Section 9-4-3, BRC 1981 was waived under Section 2-2.5-11 (g), B.R.C. 1981, as city offices are currently closed due to the COVID-19 pandemic which the city manager has declared a disaster emergency under the Boulder Revised Code. Thus, all notice requirements of section 9-4-3, B.R.C. 1981 have been met. VI. PUBLIC COMMENT AND PROCESS Agenda Item 5A Page 24 of 74 Staff received several public comments (Attachment C). Generally, most comments were opposed to the proposal and included concerns regarding traffic in the area, disturbance to the environment, and compatibility with the surrounding area. Staff also received a comment in support of the proposal in regard to the affordable senior housing and childcare uses, and one comment suggesting incorporating a use on the site that would serve the surrounding neighborhood such as a restaurant/coffee shop commercial space or rentable community room. Additionally, as described in the written statement in Attachment A, BHP has already undertaken multiple recent public engagement efforts, including an open house, a design workshop, and online design survey provided to community members and surrounding neighbors from which feedback was incorporated in the Concept Plan proposal. CONCEPT PLAN: No action is required on behalf of the Planning Board. Public comment, staff, and Planning Board comments will be documented for the applicant’s use. concept plan review and comment is intended to give the applicant feedback on the proposed development plan and provide the applicant direction on submittal of the site review plans.

The 4.9-acre site, formerly home to the Mt. Calvary Church, is situated in a walkable neighborhood with excellent access to local and regional transit, a public library, grocery store, and neighborhood serving retail. BHP is committed to redeveloping the site into a well-integrated community that provides much-needed affordable senior housing. Parcel size: 4.9 acres BVCP Land Use Designation: Medium-Density Residential Zoning: RM-2 Proposed project: 100% permanently affordable senior homes and preservation of the existing childcare center. Proposed units: 60 (56 one-bedroom, 4 two-bedroom) Agenda Item 5A Page 40 of 74 Project Background Boulder Housing Partners, in partnership with Frasier Meadows, initially purchased the Mt. Calvary property in 2016. In 2017, BHP began the site planning process and developed a concept plan for the creation of affordable senior housing on the site along with the continued operation by the Mt. Calvary Lutheran Church. This mix of uses proved complicated and had significant cost impacts to the affordable housing. As a result, in mid-2017, BHP paused the project and withdrew the previous Concept Plan application to further evaluate the shared use of the site between the Church and future affordable housing. With redevelopment paused, the site continued to operate as it had for many years with the Church and Rainbow Childcare continuing their long-standing use of the property. In late-2019 the Church found a new location for their congregation and moved out of the existing church building. Additionally, BHP purchased Frasier Meadows interest in the property and became the sole owner of the site. Given these changes in the use and ownership of the property, BHP restarted the development process in 2020 with the continued goal of providing affordable senior housing at the site. Proposed Redevelopment BHP is proposing two complimentary land uses for the site. On the southern and western portion of the property BHP is proposing creating 60 permanently affordable senior apartment homes in a single structure. The existing Narthex building would be demolished, with as much of the building recycled as possible, allowing the new senior housing building to be placed further from adjacent homes on the western edge of the site. BHP is also proposing to keep and renovate the original sanctuary building on the site to house the Rainbow Childcare Center as well as provide new community space for residents and potentially the broader community. The renovation would provide a link to the historic use of the property while preserving a unique architectural design. BHP believes that senior housing and the childcare center are complimentary land uses that would benefit from their adjacency at the site. BHP’s intention is to work with the child care center to support the continued operation of the facility at the property, however, sourcing of funds for the renovation of their specific space will need to be financed outside of the affordable housing financing and is contingent on Rainbow’s ability to find resources. Agenda Item 5A Page 41 of 74 Site Plan The site plan for the project has been developed to minimize impacts on the adjacent single-family neighborhoods to the west and north while maximizing livability for future residents. The new structure for the project will contain 60-units in a two- and three-story building that features both indoor and outdoor common amenity space. The entrance to the site off Stanford Court will provide a covered drop-off area for residents as well as an entry courtyard designed to welcome visitors to the site. The renovated sanctuary building will also be visible at the entrance, creating a mix of architectural designs and providing visual interest. Situated on the northern side of the building and connected to the entry courtyard will be a “City Lights” outdoor space. This common amenity will have expansive views over the City and surrounding foothills. Importantly, the building and the outdoor amenity space have been held back from the crest of the hill in order to minimize impacts on the neighbors at the bottom of the hill. The existing trail connecting Dover Dr to Stanford Court via the hill on the northern portion of the property will be preserved. The “City Lights” courtyard will also connect to community garden space on the western edge of the property via a landscaped ramp and stair that maintains the profile of the edge of the hill. This connection will be designed with natural vegetation to visually nestle the building into the hillside. Views from Dover, Broadway, and the south will see a building that is integrated into the surrounding natural environment. Parking will primarily be in a large lot on the east end of the site with supplementary parking located in a small surface lot to the west of the building containing 18 spaces, as well as a larger parking lot on the eastern portion of the property, containing 55 spaces. By maximizing parking on the eastern side of the property, the design team was able to reduce the size of the parking lot to the west of building, creating a community Agenda Item 5A Page 42 of 74 garden space along the western property line, providing a natural buffer for adjacent neighbors. Architecture The design team explored several alternative concepts that split the proposed housing into multiple buildings of varying sizes placed in different locations both east and west of the sanctuary building which is to be preserved and renovated. Responses from the community overwhelmingly favored a single building that eliminated any structure on the narrow eastern end of the site. Additionally, the neighborhood also favored placement of the structure as far as possible from the crest of the hill to the north and the single-family homes to the west. The proposed structure has developed out of this community input. The proposed structure is a simple and straightforward volume containing residential units organized along a double loaded corridor. The building wraps around and encloses a large outdoor living area - the “City Lights” courtyard - on the north side of the structure. The proposed building is cut into the grade that rises from east to west across the site so that the east end of the structure is three stories above grade and the west end of the structure is two stories above grade, minimizing visual impact. A primary linear volume placed parallel to the south property line contains the majority of the residential units. Two short wings extend north from this volume to enclose the courtyard. The west wing is perpendicular to the primary linear volume while the east wing is oriented at an angle that responds to the form of the sanctuary structure that will remain. The east end of the primary volume is three stories tall and extends over a covered drop off. The east wing extends to the northeast and creates both the entry court between the new structure and the sanctuary and the City Lights courtyard to the northwest. The north end of the east wing steps down to two stories in height creating an outdoor living space on the third floor while also reducing the scale of the structure where it comes alongside the existing sanctuary. The west end of the primary volume is two stories tall as a result of the grade change across the site. Parking on the west side of the site is at the second-floor level. The west wing extends to the north toward the crest of the hill. This wing steps down at the north end to minimize the visual impact of the building when viewed from the foot of the hill below. At the north end of this wing the building presents just one story above grade. As Agenda Item 5A Page 43 of 74 with the east wing, the step in the building massing creates an outdoor living space on the third floor. A third outdoor living area on the upper floor of the primary volume occurs midway along the southern side. This roof deck visually breaks what would otherwise be a very long roof edge. In total the third floor of the structure is carved away in three places, at each end of the wings and midway along the south side, to create three roof decks. These outdoor living spaces each has a unique exposure to allow residents a rich variety of outdoor opportunities at different times of day through the different seasons of the year. Programmatically the upper floors of the building are entirely residential in nature with some small communal gathering spaces located on each floor. The first floor contains both residential units and common areas. First floor residential units along the south side of the building are partially below grade and have small private outdoor patios and gardens. The first floor of the east wing contains common areas with views across the City Lights courtyard to the Flatirons and the city below. A covered walkway will connect the new structure to the existing sanctuary. A light delicate roof will provide cover to residents crossing from the new structure to the sanctuary while remaining open on both sides to allow broader community access throughout the site. Building height is to be kept as low as possible, and within the maximum allowable 35’- 0” limit where feasible, to minimize its visual impact of the structure on the top of the hill. A flat roof with parapets will be broken by smaller sloped roof elements, potentially with dormers, to visually break the top edge of the building and reduce the scale of the structure. Residential units are organized to take advantage of the spectacular views in all directions. Exterior walls of each unit step in at bedrooms to create large corner windows in living spaces that capture views in two directions. The modulation of the exterior wall, in and out, helps reduce the scale of the structure breaking it down into smaller volumes that are in keeping with the surrounding site context. The architectural character of the building facing south, and east is urban in feel while the architectural character of the building facing north and west responds to the natural appearance of the hillside below. On the north elevations the building uses materials and elements to create shadow and depth to soften the appearance and fit it into the natural landscape. Exterior cladding will be drawn from a palette of warm natural materials with some combination of stucco, cementitious panels and wood Agenda Item 5A Page 44 of 74 siding acting as the dominant materials. Colors will be muted warm grays and browns so that during winter when trees are out of leaf the building will appear to be an extension of the landscape of the hillside beneath it. Engagement As the housing authority for the City of Boulder, BHP is fully committed to a robust community engagement process for all the housing communities we develop. Throughout the 2017 iteration as well as the current development process, BHP has been committed to including the neighborhood and community in the design and development process. Beginning in 2016 with the Boulder Valley Comprehensive Plan update through the current Concept Plan BHP has been proactively creating opportunities to engage with the neighborhood and community on the Mount Calvary project. The process below outlines the engagement process to date: 2017 Engagement BHP created a robust engagement process as part of the initial development process in 2017. This included the creation of a Design Advisory Group (DAG) comprised of local stakeholders as a forum to identify concerns, provide feedback, and work together to help design a conceptual plan for the site. BHP and the design team also hosted a community design charrette that gathered project stakeholders to discuss, debate, and create design alternatives for the project. Additionally, the project team hosted an open house for the broader community to learn more about the project, held several one-on-one meetings, created a project website to share information, and offered a tour of BHP’s High Mar Senior Community to interested community members. Through the 2017 engagement process BHP identified the following priorities for the site plan and design: • Provide a buffer to the single-family homes to the west and to the north; • Ensure design compatibility with surrounding neighborhoods, • Incorporate enough parking for residents on-site, • Locate the tallest part of the proposed housing toward the south and center of the site, away from neighbors to the west and the edge of the ridge. • Maintain the neighborhood trail form Dover Street through to Stanford Court, • Provide a community garden as an amenity for the residents and possibly the local neighborhood. Agenda Item 5A Page 45 of 74 Although the concept plan for the property was ultimately withdrawn in 2017, BHP and our design team integrated the principles and priorities described above into our planning and engagement process in 2020. 2020 Engagement Upon restarting the planning process for the site in 2020, BHP reengaged with the community through a series of open houses, design workshops, and online engagement tools. These events were designed to familiarize the community with the change in project parameters as well as get input of the design of the site given the change in programming. Through these events, BHP was able to build on the input received in 2017 while also getting specific feedback on the current site design. A summary of the community engagement events in 2020 is below: January 2020 Open House BHP hosted a community open house to introduce the project team to the neighborhood, provide an overview of the history of the site, and map out the process for redevelopment of the property moving forward. The Open House was well attended by both neighbors of the project and individuals interested in living at the future site. Our sign in sheet estimates attendance at 23. Agenda Item 5A Page 46 of 74 February 2020 Design Workshop BHP and our design team hosted a workshop to gain initial feedback on a number of conceptual site designs. Approximately 30 members of the community attended the workshop. The project team walked participants through three conceptual site plan layouts and engaged in a robust discussion of each concept. Pros and cons of each plan were explored with participants and at the conclusion of the meeting community members indicated their preferences by voting with blue dots. o From this design workshop, the following principles and preferences were identified:  Maintain the trail up the hill and through the site.  Maintain the ‘forest’ below the sanctuary as a visual barrier and as a wildlife corridor.  Keep the building back from the edge of the hill.  Provide as much as a buffer on the west side as possible.  Minimize of eliminate buildings on the east side of the site.  Focus on solutions to traffic and transportation impacts. o At the conclusion of the meeting, participants indicated the following preferences for each of the three site plans: Agenda Item 5A Page 47 of 74 April 2020 Design Survey Given the impacts of the COVID-19 pandemic, BHP was unable to host a planned in- person community meeting in March. In order to continue the conversation with the community around the design of the site, BHP and the design team developed an online survey to gain community input. The survey walked respondents through the information presented at the February 2020 workshop and presented three site design concepts. Participants were asked to rank their preferred site plans and designs and provide input on a series of design characteristics. The survey was sent to 170 community members who had previously signed up to receive updates on the Mount Calvary project. BHP received over 90 responses to the survey, including from neighbors, those interested in living in affordable senior housing, and broader community members. The high response rate and diversity of respondents provided incredibility valuable feedback for the design team. The full survey can be viewed here: https://www.surveymonkey.com/r/mtcalvary Through this process, BHP identified and incorporated the following priorities and principles for the site: •Incorporate a covered drop-off area for residents. •Provide multiple outdoor gathering areas for residents. •Minimize visual impact from the bottom of the hill as well as the west side of the site. •Provide community garden space. •Provide landscape buffers for adjacent neighbors to the west and north. •Maintain the hillside area as wild. •Maintain the ‘forest’ below the sanctuary. •Design the building to be a mix of 2 and 3 stories. •Provide adequate parking on-site for residents. •Utilize building materials and colors that blend with the natural environment. Utilizing the results from the design survey, input received in previous meetings, and BHP’s program for the project, the design team developed the Concept Plan included in this submittal. Agenda Item 5A Page 48 of 74 Sustainability BHP has a commitment to environmental, social, and economic sustainability. The Mount Calvary project will incorporate these principles through thoughtful design, resident services, and by providing financial stability to rent-burdened Boulder seniors. Techniques and Strategies for Environmental Impact Avoidance, Minimization, or Mitigation The Mount Calvary Senior Housing project will be designed to minimize environmental impact and promote sustainable design. The proposed redevelopment will keep the building massing located on the southern portion of the site. This location will minimize disruptions to area wildlife and preserve the hillside on the northern edge of the site as undeveloped. In addition, the building will be located where an asphalt surface parking lot currently exists, taking advantage of already developed areas of the property for the redevelopment. The project will also be certified under the Enterprise Green Communities program, which includes specific criteria related to sensitive site development, minimization of site construction impacts, and environmental management. Techniques and Strategies for Practical and Feasible Transportation Demand Management Techniques BHP is committed to providing sustainable transportation options and management techniques for the Mount Calvary Senior Housing project. Providing access to alternative modes of transportation is an essential function of BHP’s approach to transportation demand management (TDM), and we anticipate providing a robust program at Mount Calvary. Consistent with the recommendations included in the Preliminary Traffic Study prepared for this submittal by Kimley-Horn, BHP would seek to implement several TDM strategies to reduce the number of vehicle trips to and from the site. This would include the expansion of current BHP programs such as EcoPasses for residents, discounted B-Cycle memberships, reduced cost eGo CarShare memberships, Via Transportation shuttles, ride sharing opportunities, and resident education on alternative modes of transportation. The project site is also located in a transit rich area with local and regional bus services readily available as well as abundant retail, grocery, and shopping options located within walking distance. In addition, BHP sees significantly lower car ownership in our affordable senior communities when compared to the general population. For instance, at BHP’s High Mar senior community, also located in South Boulder, out of 59 households only 36 owned vehicles as of February 2020. This experience is consistent with the conclusions of the preliminary traffic study, which state that the proposed Mount Calvary Senior Housing project will generate a very low traffic volume. Agenda Item 5A Page 49 of 74 Community Benefit The Mount Calvary Senior housing project supports both the City’s long-term goals as well as the objectives of the Boulder Valley Comprehensive Plan. The redevelopment of this site will provide significant community benefit through the provision of new, permanently affordable senior housing. The proposed 60-units will be affordable to seniors age 55 and over who earn less than 60% of the Area Median Income. For an individual, this equates to an annual household income of less than $48,360 per year. This much-needed housing will address the growing demand for senior housing available at rents that are affordable to those earning modest incomes. The project will also incorporate significant accessibility features to promote flexibility for residents to age in place and accommodate changing living and mobility needs over time. Conclusion Thank you for your consideration of Boulder Housing Partners Concept Plan for the redevelopment of the Mount Calvary property. We look forward to working with the City and Boulder community to make this important project a reality.

The previous Mount Calvary Lutheran Church will be redeveloped with this project, planned to include 60- residential units for senior housing. The development will be built to the west of Stanford Court, north of Stanford Avenue in Boulder, Colorado. A vicinity map illustrating the project location is attached as Figure 1. Of note, an existing 25-student daycare with six to seven staff are currently operating out of the building. This daycare use is proposed to remain in the future, and since it is already in existing traffic volumes and street network roadways and intersections volumes and operations, it is not included specific to this proposed additional senior housing project. Primary access to the site will be provided by Stanford Court and Stanford Avenue. The proposed direct access will be from Stanford Court. Adjacent to the site, Both Stanford Avenue and Stanford Court provide one through lane of travel in each direction, with a posted speed limit of 25 miles per hour. Additionally, Stanford Avenue and Stanford Court will serve as local access to the development. As part of this letter, the intersections of Stanford Court / Stanford Avenue (unsignalized), Stanford Avenue / Table Mesa Drive (unsignalized), and Table Mesa Drive / Broadway Street (signalized) were evaluated. The existing lane configurations for the study intersections are provided attached as Figure 2. Site-generated traffic estimates are determined through a process known as trip generation. Rates and equations are applied to the proposed land use to estimate traffic generated by the development during a specific time interval. The acknowledged source for trip generation rates is the Trip Generation Manual1 published by the Institute of Transportation Engineers (ITE). ITE has established trip rates in nationwide studies of similar land uses. For this study, Kimley-Horn used the ITE Trip Generation Report average rate equations that apply to Senior Adult Housing - Attached (ITE Code 252). The following table summarizes the estimated trip generation for the project (calculations attached).

Distribution of site traffic on the adjacent roadways and through the three study intersections was based on the area street system characteristics, adjacent roadway network, surrounding area development information, and the proposed access system for the project. The directional distribution of traffic is a means to quantify the percentage of site-generated traffic that approaches the site from a given direction and departs the site back to the original source. It is anticipated that 40 percent of site generated traffic will enter and exit to the northwest along Broadway Street, 30 percent will enter and exit to the east along Table Mesa Drive, 20 percent will enter and exit to the southeast on Broadway Street, and 10 percent will enter and exit to the west on Table Mesa Drive. Attached Figure 3 illustrates the expected project trip distribution. Traffic assignment was obtained by applying the distribution of Figure 3 to the estimated traffic generation of the project shown in the previous table. The Mount Calvary Senior Living traffic assignment is shown in Figure 4 attached. The overall development is anticipated to generate less than 100 trips during the peak hours. Based on the distribution and assignment, a minimal increase of traffic is anticipated at the three study intersections. In addition, this letter provides initial recommended Transportation Demand Management (TDM) strategies f or consideration with the proposed Mount Calvary Senior Living project. In general, TDM Plans are designed to improve the people moving capacity and efficiency of the existing roadway network by attempting to maximize the number of people travelling within each vehicle, or by influencing the time of day or need for travel within the street network. At residential developments, such as the proposed Mount Calvary Senior Living, there are several TDM measures available for consideration to minimize the number of single occupant vehicles being generated by the project. These measures typically include: • Carpools and Vanpools • Public and Private Transit • Non-Motorized Travel (Bicycling and Walking) The goal of vehicle trip reduction is to reduce the number of singl e occupancy vehicles traveling to and from Mount Calvary Senior Living. The advantages of shifting drivers from single-occupant vehicles to other modes of travel are that average daily traffic volumes are decreased, air quality is improved, and wear and tear on the City of Boulder roadways are reduced, thereby reducing maintenance costs. The primary disadvantage of the TDM mode shift measure is that success of this element depends on the willingness and continued cooperation of residents, most of whom travel, and prefer to travel, in the drive-alone mode. Mount Calvary Senior Living will be designed to incorporate onsite facilities to accommodate and encourage TDM measures. Site Design Currently, sidewalks exist along the east side of Stanford Court and both sides of Stanford Avenue between Mount Calvary Lutheran Church and the Table Mesa Drive/Stanford Avenue intersection. Sidewalks also are located along both sides of Table Mesa Road to Broadway Street. An on-street bicycle lane is designated along westbound Table Mesa Road through the Stanford Avenue intersection. Three Regional Transportation District (RTD) transit routes serve the project area, which includes Route 204, Route 206, and the SKIP Route. RTD Route 204 is named Table Mesa/Moorhead/North 19th that connects the Table Mesa Shopping Center to the CU Campus and the Downtown Boulder Station. RTD Route 206 is named Pearl/Manhattan/Fairview High School that connects Table Mesa Agenda Item 5A Page 52 of 74 Mr. Swallow March 26, 2020 Page 3 kimley-horn.com 4582 South Ulster Street, Suite 1500, Denver, CO 80237 303 228 2300 Drive to the Boulder Junction at Depot Square Station Flatiron Flyer along Pearl Parkway. The RTD Route Skip travels along Broadway and connects Table Mesa Drive to CU Campus and north towards US 36 near the Boulder County Housing Authority. Eastbound Table Mesa Drive contains a transit stop east of Stanford Avenue which serves all three routes. Two transit stops are located along westbound Table Mesa Drive both east and west of Stanford Avenue and primarily serves Route 204 The following provides elements of the site design being implemented as part of a TDM plan that connects to these surrounding facilities: • New sidewalks connecting to the Mount Calvary Senior Living building • Perimeter sidewalk connections to the existing sidewalk along Stanford Court, thereby providing pedestrian connections to the existing network and system. • Conveniently located on site bicycle racks for residents that can be monitored for security purposes. In addition, there will be indoor secure bike storage locations available for resident use. Programs and Education The alternative transportation modes of ride-sharing and transit are the two areas where the greatest amount of effort will be concentrated in the development of a TDM Plan for Mount Calvary Senior Living. These two modes have the best potential to encourage a travel mode shift that would minimize the number of vehicle trips made to and from Mount Calvary Senior Living over the course of a day. The potential for ride sharing is restricted by the geographical distribution of attractions for the Mount Calvary Senior Living residents. In addition, this is influenced by the residents’ desired travel times and schedules. The potential for ride-sharing generally increases as the number of residents increase. It is recommended that a Transportation Demand Management (TDM) plan be implemented for the proposed Mount Calvary Senior Living project. The plan should incorporate incentives to minimize vehicle trips on the adjacent street system and to encourage residents to travel via modes other than single occupant vehicle (SOV). Upon reviewing travel characteristics for residents of the proposed Mount Calvary Senior Living development, several incentives are recommended for consideration as part of a comprehensive Transportation Demand Management plan for the project. These recommendations are being provided to minimize peak hour vehicle trips on the street system and encourage the residents to travel via a mode other than single occupant vehicles (SOV). The following provide a summary of the recommended program: • Establishment of Transportation Information. The office would have responsibility for the coordination of transportation information disseminated to the residents. The City of Boulder and Go Boulder will assist in preparing “Welcome” kits to provide this information in binders. This may include the following: o Bicycle route maps o Transit route maps o Familiarization with public transit options and nearest stop information o Benefits of public transit, bicycling, and walking • Implementation of a Ride Sharing Program. The residential development would oversee a ride sharing program to include: o Exploration of options for creating informal ride sharing arrangements o Preferential parking spaces for participants o Awards for sustained participation o Benefits of ride-sharing After residents have been living within Mount Calvary Senior Living for a year, the City of Boulder will perform a survey of the residents to determine the effectiveness of the TDM plan. The City of Boulder Agenda Item 5A Page 53 of 74 Mr. Swallow March 26, 2020 Page 4 kimley-horn.com 4582 South Ulster Street, Suite 1500, Denver, CO 80237 303 228 2300 will administer the survey. The City will work with the residential owner to obtain the email addresses of the residents to provide a link to the survey site. The traffic analysis presented herein for the proposed Mount Calvary Senior Living development demonstrates that Mount Calvary Senior Living generates a very low traffic volume. This traffic volume, when distributed and assigned to the street network, further reduces the traffic volume compared to the existing traffic volumes on the roadways and through the subject intersections. Based on this, it is anticipated that Mount Calv ary Senior Living will not have a significant impact to existing traffic conditions and operations.
