STAFF RECOMMENDATION: Staff recommends that the Landmarks Board adopt the following motion: The Landmarks Preservation Advisory Board approves a landmark alteration certificate to construct a new 440 square foot, one story, two car garage at the contributing property at 512 Marine Street in the Highland Lawn Historic District in that the proposed construction meets the requirements set forth in Chapter 9-11-18, B.R.C.1981, subject to the conditions below, and adopts this memorandum as findings of the board. CONDITIONS OF APPROVAL The applicant shall be responsible for ensuring that the development shall be constructed in compliance with all approved plans on file in the City of Boulder Planning Department, except as modified by these conditions of approval. 2. Prior to a building permit application, the Applicant shall subrnit, subject to the final review and approval of the Planning Director final architectural plans A¢enda Item #5C Paee 1 S:~PLANWataUongrang~HIS7~ALTCERTSU-listoric Districtsu-lighland LawnVdarine.512\02.06.08 Memo.doc showing details regarding landscaping and hardscaping. The applicant shall demonstrate that the design details are in compliance with the intent of this approval and the General Design Guidelines. This recommendation is based upon staff's opinion that with the conditions listed above, the proposed construction will be generally consistent with the conditions as specified in Section 9-11-18(a)&(b)(1-4) B.R.C., and the General Design Guidelines. SUMMARY: • On Apri16~, 2007, the Design Review Committee approved a landmark alteration certificate for the 'rehabilitation of historic house and addition of dormers and rear south elevation addition, all as shown on drawings dated 04/02/2007". • The front gabled, brick house was constructed around 1900 and is considered a contributing resource to the Highland Lawn Historic District. • Though the alleyways of the Highland Lawn Historic District are not considered contributing elements to the district, the existing accessory building is a contributing feature. • The proposed structure will be set back 8 feet from the existing building so that the new construction will be secondary to the historic resource. • The roof pitch and trim of the new construction will closely match the existing building. The proposed siding will have a 3" exposure, similar to the existing 2'fi" exposure. Gate type doors will be used on the proposed construction. • Improvements are planned for the existing structure, pending staff review and approval. -i - ~ FBI-IMF k rE` ~ iw~ 0 D ~ Q DD ~ ~ 0 Figure 1. Location Map, 512 Marine Street DISTRICT HISTORY: Aeenda Item #SC Pa¢e 2 The 10,081 sq. ft. subject property is located in the Highland Lawn Historic District, which was designated as a local historic district by the City Council in May 2005. tlannah Barker platted the middle-class neighborhood in 1884 as the Town of Highland Lawn. The area is significant for its association with historic persons and events and as an excellent collection of buildings reflecting architectural styles of the period. The Town cif Highland Lawn included 19 large lots (100 x 400) bounded by Boulder Creek to the north, University Street at the south, and 6~ and 4~ Streets on the east and west respectively. Originally located south of Boulder's city limits, the town remained an independent community until 1891. Barker's plan for the neighborhood showed foresight: each lot included water rights in the adjacent Anderson ditch and buyers were encouraged to plant trees (cottonwoods were specifically excluded), and build fences around their properties. The new town was located on a gentle slope with Flagstaff Mountain as a backdrop, and the popular sight seeing rail line from Boulder to Eldora and Ward, known as the "Switzerland Trail of America" was adjacent to the neighborhood on the north side of Boulder Creek. I~1one of the original owners built in the neighborhood, choosing instead to subdivide the nearly one-acre parcels into smaller lots. Most of the lots were bisected by alleys running east -west through the district. Marine Street was originally Vine Street and was renamed Marine Street sometime in the 1890s after prominent early settler Marinas Smith. Lots in the district are generally long and narrow with principal buildings situated close together at the front of the lots and accessory buildings oriented to the alleys. Because they contain a relatively low number of buildings from the period of significance with historic integrity, and because the district boundaries bisect the rear alleys, the alleys (located at the north and south edges of the district) are not significant historic elements of the district. However, the alley building on this property is one of only two accessory buildings considered to be contributing to the district. ~ q~~ ~ s I 7 ~ I 1 ~ ~ 1 4 t \ ~ 300 ~ 'N~ E y { ~ . \ - - - - f r - ~ I~ Figure 2.

The proposed new garage is located 19 feet from the alley on the south edge of the property, 3 feet from the east property line, 9'8" from the existing building, and approximately 90 feet from the main house. The north and south sides of the garage are 20 feet in length and the building is 14'5" in height at the peak of the roof. The secondary sides, the east and west, are 22 feet in length. The proposed fenestration is simple; the south elevation, which faces the alleyway, is dominated by a sliding gate garage door, which is complimentary to the door on the existing garage. The north elevation, which faces the yard, is also simple in fenestration; it includes 2 double-hung windows, which flank an 8 foot by 21/z foot stone planter. The east and west elevations have no fenestration, except for a door on the west elevation. Both the trim and the pitch of the roof reflect that of the existing garage. - ~ sir L i i i --r _ ~ ~ ~ E+ i~ i~ ~ J ~i - ~ _ L oaerw~ en~.ae ~ - - - - - - rew owe - - - - SOUTH ~EVAT1QfV scaeF ~ va•~-0' Figure 4.

Does the proposed application preserve, enhance, or restore, and not damage or destroy significant exterior architectural features of the landmark or the subject property within an historic district? Response: Staff finds the proposed new construction is consistent with the General Design Gecidelines (see design guidelines analysis section) and will not compromise the contributing property. Z. Does the proposed application adversely affect the special character or special historic, architectural, or aesthetic interest or value of the property or district? Response: Staff finds that the proposed application will not adversely affect the special character of the property or Highland Lawn Historic District. Staff also considers that the proposed new construction is generally compatible with the General Design Gecidelines. 3. Is the architectural style, arrarcgernent, texture, color, arrangement of color, and materials used on existing and proposed straectures compatible with the character of the historic district? Response: The staff finds the new construction will be compatible with the architectural style, arrangement, texture, color, arrangement of color, and materials on the historic buildings. The Landmarks Board is required to consider the economic feasibility of alternatives, incorporation of energy-efficient design, and enhanced access for the disabled in determining whether to approve a Landmark Alteration Certificate. Response: No information has been provided to suggest that energy efficient design or accessibility has been considered beyond that required by the city's building code. 5. Is the proposed application consistent with the purposes of Chapter 9-11, "Historic Preservation," B.R.C. 1981? Response: The proposal respects the character of the setting, does not imitate surrounding buildings, and represents a contemporary, yet compatible design for an accessory building (see design guidelines analysis section). DESIGN GUIDELINES: The Historic Preservation ordinance sets forth the standards the Landmarks Board most apply when reviewing a request for a landmark alteration certificate and the board has adopted the General Design Guidelines to help interpret the ordinance. The following is an analysis of the submitted proposal with respect to relevant guidelines. It is important to emphasize that design guidelines are intended to be used as an aid to appropriate design, and not as a checklist of items for compliance. Agenda Item #SC Page 7 The following is an analysis of the proposal's compliance with the applicable design guidelines: GENERAL DESIGN GUIDELINES FOR GARAGES 1X OTHER ACCESSORY BUILDINGS, 7.0 7.1 Existin Historic Accesso Structures .1 Retain and Preserve garages and accessory The existing garage will be preserved, YES buildings that contribute to the overall and the new building will be set 9'8 historic character of the individual building from the edge of the existing building. site or the district. 7.2 New Accesso Buildin s New accessot-t/ buildings should follow the iharucter and pattern ur histur-ic ace~~ssort~ structures. bvhile thc~~ should take design cues from the primary structures, they must be subordinate in size, massing, and detailing.

BOARD'S DECISION: The Historic Preservation Ordinance specifies that a Landmark Alteration Permit may not be approved by the Board or City Council unless it meets the conditions specified in Section 9-11-18 B.R.C. Specifically: (a) The landmarks board and the city council shall not approve an application for a landmark alteration certificate unless each such agency finds that the proposed work is consistent with the purposes of this chapter. (b) Neither the landmarks board nor the city council shall approve a landmark alteration certificate unless it meets the following conditions: (1) The proposed work preserves, enhances, or restores and does not damage or destroy the exterior architectural features of the landmark or the subject property within an historic district; Agenda Item #SC Page 9 (2) The proposed work does not adversely affect the special character or special historical, architectural, or aesthetic interest or value of the landmark and its site or the district; (3) The architectural style, arrangement, texture, color, arrangement of color, and materials used on existing and proposed structures are compatible with the character of the existing landmark and its site or the historic district. FINDINGS: Provided the conditions outlined in the staff recommendation are met, staff recommends that the Landmarks Board adopt the following findings: 1. The proposed garage will not have an adverse effect on the special character and special historical, architectural and aesthetic interest and value of the district, as they will be compatible in terms of mass, scale, or orientation with other buildings in the district. The proposed design will not have an adverse effect on the special character and special historic, architectural and aesthetic interest and value of the district. 3. In terms of mass, scale, and orientation the proposed garage complies with Section 7.0(1-14), of the General Design Guidelines for Landmarks and Historic Districts.
