Elaboration:The open lawn area of Central Park from
Canyon Boulevard to White Rock Ditch is visible in a 1920s
photographs, however the addition of the Bandshell,
constructed in 1938, unified the design of Central Park. The
1995 Band shell Report by Front Range Research notes
“Landscaping around the shell was completed in 1939” and
modified in 1950 with the addition of the seating

Distinction in Development of
the Community
Central Park and Boulder Creek
Elaboration:The proposed boundary expansion to the White Rock Ditch
(all of Block 13) includes land acquired by the city between 1906-1933
specifically for use as a civic park. Formal planning for the park began c.
1907-1910 Frederick Law Olmsted, Jr.’s suggestions to reimagine Boulder
Creek as a "pretty, shady spot with a clean park path running beside the
murmuring water …”Construction of the Bandshell in 1938 with
associated landscape improvements including the planting of trees and
expansion of pathways across the park saw the area development into a
center of civic celebration in the park that continues to the present.

European Influences Public Landscape Design
Elaboration:As is typical of designed landscapes, Central
Park has evolved over time. However, the essential historic
character of the site remains; The landscape was consciously
designed by Saco DeBoer over a period spanning 1938 -1950.
The expansive lawn, trees and pedestrian paths through the
area exemplify European-style civic park design favored by
DeBoer at the time.
01
Architect or Builder of
Prominence
Saco DeBoer and Glen Huntington
Elaboration:The expanded boundary is associated with the design
intent for a central park area as originally envisioned by Frederick
Law Olmsted in the early twentieth-century and Saco R. DeBoer's
realization of this vision as consulting city planner to Boulder’s
Planning and Parks Commission in the 1930s and 1940s. The historic
landscape was designed specifically to complement the 1938
Bandshell, designed by Glen Huntington. The Bandshell was situated
by Huntington and DeBoer to encourage passersby into the park and
to provide a comfortable gathering space for concerts and other
open-air activities.
02
Artistic Merit
None Observed.
Example of the Uncommon: The Bandshell is Boulder’s only
example of park bandshell construction and one of the few
such examples in the state. However, the associated park is
not uncommon in Boulder.

Environmental
Significance
Site Characteristics
The proposed landmark expansion is environmentally significant for its
planned and natural site characteristics. The bandshell and its open-air
seating and treed lawn area have long served as the focus of Central Park
and as a civic center for social and cultural events in Boulder.
01
Compatibility with Site
The open lawn, informally planted mature trees and
pathways contribute to the historic character of Central Park
and the setting of the Bandshell as its central element.
02
Geographic Importance
Central Park and the Bandshell comprise an established, familiar, and
prominent visual civic landmark located near Boulder Creek, the White
Rock Ditch on major thoroughfares that has been an important gathering
place in central Boulder since the Bandshell’s construction in 1938. The
Bandshell is uniquely located as a focal point of Central Park in
Downtown Boulder and was consciously situated to encourage passersby
to enter the park for entertainment and relaxation.
03
Environmental Appropriateness
Expansion of the landmark boundary south to the White Rock ditch is
appropriate given the design and orientation of the bandshell facing
south to the park with planned seating, a mature tree canopy for
shade and open lawn for additional seating and recreation.
04
Area Integrity
The character of the property has changed very little since the
Bandshell’s seating area, also designed by Saco DeBoer and contributing
to the character of the site, was added in 1950. The southern portion of
the site has remained an open lawn with informally planted trees and
unpaved paths since at least 1938. The pathways on the east and
southern edges of the site were added in 2008. These non-historic
changes do not detract from the historic character of the site.

35
Staff considers that moving forward with the proposed
landmark boundary expansion, at this time, would not be
appropriate:
•The area of Central Park considered for expansion is not
threatened and any changes to the Bandshell or seating,
including relocation or rehabilitation, would require review
by the Landmarks Board.
•Expanded area would more logically be included in a Civic
Area historic district encompassing all Individual
Landmarks in the in the area including the Bandshell &
Park, the Boulder/Dushanbe Teahouse, City Transfer and
Storage Building, Atrium Building, and Penfield Tate II
Municipal Building) better recognizing & protecting the
historically significant setting for each of these landmarks.
•Staff, the Landmarks Board, the Planning Advisory Review
Advisory Board (PRAB) will work together to ensure that
any changes to the Civic Area reflect the area’s historic and
cultural significance and the City Council-approved Area
Master Plan
Carnegie Library for Local History
36
The Landmarks Board does not recommend the City Council
expand the designation boundary of 1236 Canyon Blvd., to include
all of Block 13 as a local historic landmark finding, that at this time,
it would not meet the standards for individual landmark
designation in Sections 9-11-1 and 9-11-2 B.R.C. 1981, and adopt the
staff memorandum dated April 6, 2022, as the findings of the board.
Recommended Motion
Planning & Development Services | Historic Preservation37
Staff recommends that, at this time, the Landmarks Board not forward a
recommendation to the city council to amend the landmark boundary for the following
reasons:
1.As an existing individual landmark, any changes to the Bandshell or seating, including relocation or
rehabilitation, already requires review by the Landmarks Board.
2.The areas of Central Park south of the existing boundary are currently city park. In 2021, City of
Boulder voters approved funding for an extension of the Community, Culture, Resilience and Safety
tax, which included funding for enhancements to the Civic Area Phase II, including Central Park.
Landmarks Board and the PRAB will have opportunities to work together to ensure that these plans
reflect the historic and cultural significance of this area and the City Council-approved Civic Area
Master Plan.
3.The area considered for expansion would more logically be included in a future civic area historic
district which could encompass all of the existing individual landmarks in the civic area (the
Bandshell, the Boulder –Dushanbe Teahouse, the City Transfer and Storage Building, the Atrium
Building, and the Penfield Tate II Municipal Building) and better protect the historically significant
setting for each of these landmarks. While staff do not have capacity for this in 2022, it could be
considered in 2023.
Proposed Findings
Planning & Development Services | Historic Preservation38
Staff suggests the Landmarks Board and the PRAB continue to work together as planning for
the East Civic Area/Central Park continues.
Within 45 days of the hearing date, the Landmarks Board must adopt specific written findings
and conclusions approving, approving with modifications, or disapproving the application.
Should the board disapprove the application, the board must notify the City Council of that
action within 30 days of the hearing date. City Council may call up a decision disapproving a
designation. Should an application be disapproved, the same application may not be
submitted for a period of one year.
If the board finds that the proposed designation conforms to Sections 9-11-1 and 9-11-2, B.R.C.
1981, it shall adopt specific findings and conclusions approving or modifying and approving the
application. If the board approves the proposed designation, the application will be forwarded
to City Council (within 45 days) for a public hearing. The public hearing before City Council
must be held within 100 days of the Landmark Board’s decision recommending designation.
Next Steps
Planning & Development Services | Historic Preservation39
The Landmarks Board recommends the City Council expand the designation
boundary of 1236 Canyon Blvd., to include all of Block 13 as a local historic
landmark finding, that at this time, it would meet the standards for individual
landmark designation in Sections 9-11-1 and 9-11-2 B.R.C. 1981.

Design Guideline Analysis
9-11-18 (b) & (c), B.R.C. 1981
Planning & Development Services | Historic Preservation75
Planning & Development Services | Historic Preservation76
Staff considers that the following changes to the proposal are necessary to ensure consistency with
the General Design Guidelines for Boulder’s Historic Districts and Individual Landmarks and the
Mapleton Hill Historic District Design Guidelines:
•Because the addition will be visible from Mapleton Avenue and the alley, staff considers that the perceived and real
mass, scale, and height should be meaningfully reduced to ensure that it is subordinate to the historic house. This
will likely require reducing its footprint and revising the two-story volume to a one and one-half story, more roof-
dominated addition better reflecting the character of the historic house;
•Revise side dormers to better reflect the forms of those on the historic house;
•Exploration of the feasibility of restoring the east (side) screened-in porch to its pre-1964 appearance and
configuration based upon the c.1949 tax assessor photograph;
•Exploration of the feasibility of utilizing the upper-level of the pre-1929 addition to create passage from the historic
house to the addition, understanding that do so may require support from the Landmarks Board for variances from
the Board of Zoning Adjustment per 9.2.3(h)(4) Designated Historic Property of the Boulder Revised Code;
•Simplification of the fenestration of the addition to better reference pattern and proportions on the historic house.
Large banks of “nano doors” at rear are incompatible with character of main house and should be reduced;
•Minimize the extent to which regrading is necessary and limit the amount of mature vegetation will be lost on the
property;
•Provide all material and design details including all-wood windows and doors, siding, railing, roofing and wood-
decking, colors and hardscaping materials.
General Design Guideline Summary
1.The applicant shall be responsible for completing the work in compliance with the approved plans, except as modified by these
conditions of approval.
2.Prior to submitting a building permit application and final issuance of the Landmark Alteration Certificate, the applicant shallsubmit
the following, which shall be subject to final review and approval by the Landmarks Design Review Committee (LDRC) to ensure that
the final design of the addition is consistent with the General Design Guidelines, the Mapleton Hill Historic District Design Guidelines
and the intent of this approval:
a.Revised drawings showing:
i.A meaningful reduction in the perceived and real mass, scale, and height of the addition to ensure that it is subordinate to
the historic house. This will likely require reducing its footprint and revising the two-story volume to a one and one-half
story addition that is more roof dominated to better reflect the character of the historic house;
ii.Revised dormers to better reflect the forms of those on the historic house; Restoration of the east (side) screened-in
porch to its pre-1964 appearance and configuration based upon the c.1949 tax assessor photograph;
iii.Simplification of the fenestration of the addition to better reference pattern and proportions on the historic house;
elimination of the large banks of “nano doors” at rear and groupings of windows;
iv.Minimize the extent to which regrading is necessary and limit the amount of mature vegetation that will be lost on the
property;
b.Final architectural plans that include details including details for exterior doors, windows (including placement, style, and
type), lighting, paint and roofing color, composition of walls, etc.
Conditions of Approval
77
The Landmarks Board adopt the staff memorandum dated April 6, 2022, as the
findings of the board and conditionally approve a Landmark Alteration Certificate
to construct a rear, one and one half-story 1,501 sq. ft. addition to the main house
at 936 Mapleton Ave., a contributing property in the Mapleton Hill Historic
District, as shown on plans dated December 3, 2021, finding that the proposal
meets the Standards for Issuance of a Landmark Alteration Certificate in Chapter
9-11-18, B.R.C. 1981 and is generally consistent with the General Design
Guidelines provided the stated conditions are met.

Design Guideline Analysis
9-11-18 (b) & (c), B.R.C. 1981
Planning & Development Services | Historic Preservation106
General Design Guideline Analysis
Front porches are a common and important visual element of many historic building styles. The porch
roof is generally supported by freestanding columns or by columns resting on a masonry wall. Wood
railings are anchored with masonry or wood balustrades. A porch is generally open with the facade of
the house plainly visible.
.3 Maintain the height, detail and spacing of the original balustrade if replacing, extending or adding balustrades.
.5 If a rear or side porch is to be enclosed, the following guidelines apply:
•Maintain the sense of openness, scale, proportion, and separation from the structure of the house. The enclosure
should not obscure the main architectural details of the porch or house.
•Keep the design and materials as simple as possible rather than trying to match the building facade.
.8 Porches on new buildings or on non-contributing buildings should be compatible with the architecture of the building,
incorporating traditional scale and proportions with updated design details.
107
Analysis:
•Photographic evidence indicates that the porch never included a railing;
•The simplicity and lightness of the proposed railing design will not obscure the architectural details of the house;
•The railing design is simple and will complement the architecture of the house, however the quatrefoil element is more
typical of a Gothic Revival architecture;
•Recommend removing the quatrefoil element or including a detail that is compatible with, and takes cues from, the
architecture of the building. For example, the original diamond detailing in the windows in lieu of the quatrefoil pattern.
General Design Guideline Summary
In this case, staff considers the installation of a railing at the front porch appropriate, due to these
factors:
•The proposed railing is an effective and necessary for life-safety ;
•The proposed railing is sensitive to the open appearance of the house; it will be subtle and keeps the
facade of the house plainly visible;
•A 36” tall railing is proportional to the two-story volume of the front porch;
•The proposed railing is freestanding not connecting to columns or walls, is reversible, and therefore
will not damage historic material.
Staff considers that the following changes to the proposal are necessary to ensure consistency
with the General Design Guidelines for Boulder’s Historic Landmarks:
•Modification of the design to be better reflect and be more compatible with the Neo-Classical
architecture of the building (consider utilizing diamond form on rail found on windows rather that
quatrefoil pattern).
108
I move that the Landmarks Board approve a Landmark Alteration Certificate to
construct front porch railings at 745 Highland Ave., an individual landmark
and contributing property in the Mapleton Hill Historic District, as shown on
plans dated September 22, 2021, finding that the proposal meets the
Standards for Issuance of a Landmark Alteration Certificate in Chapter 9-11-18,
B.R.C. 1981 and is generally consistent with the General Design Guidelines.
Recommended Motion
Planning & Development Services | Historic Preservation109
1.The applicant shall be responsible for completing the work in compliance with the approved
plans, except as modified by these conditions of approval.
2.Prior to submitting a building permit application and final issuance of the Landmark Alteration
Certificate, the applicant shall submit final architectural plans and specifications to staff for its
final review and approval to ensure that the final design of the railings are consistent with the
General Design Guidelines and the intent of this approval.
a.Revised railing detailing to simply reflect design elements found on historic portions of
the house, for example the diamond pattern in the front windows.
Conditions of Approval
110
The Landmarks Board finds that with the stated conditions the project meets the
standards for issuance of a Landmark Alteration Certificate set forth in Section 9-11-18,
“Standards for Landmark Alteration Certificate Applications,” B.R.C. 1981. In reaching this
conclusion, the Board considers the information in the staff memorandum dated April 6,
2022, and the evidence provided to the Board at its April 6, 2022 meeting. Specifically, the
Board finds, if the stated conditions are met, that:
1.The proposal will be generally consistent with the purposes of this chapter, in that the
proposed work will not damage the historic character of the landmark property;
2.The proposed work will preserve, and will not damage or destroy the exterior architectural
features of the landmark;
3.The architectural style, arrangement, texture, color, arrangement of color and materials
used on the building will be compatible with the character of the existing landmark and its
site; and
4.The proposed work will not adversely affect the special character or special historic,
architectural, and value of the landmark property, as it is generally consistent with the
General Design Guidelines and will generally comply with Sections 2.0 and 3.3 of the General
Design Guidelines and Section 9-11-18(b)(3) of the Boulder Revised Code 1981.
