Some small substantive changes including implementation of the energy efficiency project, and others may be included. If substantive changes are included, what public process will be included'? LPAB role will be in reviewing proposed changes, and holding hearing on rule making to revise guidelines. Revise Designation Applications (Project Coordinator: Chris) This project entails revising the individual landmark and historic district designation applications. Aspects to investigate are the form itself, whether to include more research by the applicant, or justification, etc. LPAB role will be advisory in making comments on the proposed application changes. HIS Case Management/Clean Up (Project Coordinator: Chris & Alice) To organize, purge, and scan all HIS files from approximately 2001 to present. This includes creating cases as far back as 1999 in LandLink for projects which were never assigned a case number, then organizing files, and preparing them for scanning. The files will then all be sent our for contract scanning. After the files are scanned, historic preservation staff may be asked to assist records staff with loading the scanned files into content manager. There is no LPAB role on this project. Update Notebook (Project Coordinator: Chris) This project is a complete overhaul of the historic preservation notebook, to update sections, include explanation of processes, and purging of outdated or ineffective information. LPAB Role will be receiving new binders at the conclusion of the project. Enforcement Provisions (Project Coordinator: Chris) This project was a request of the board as part of the code change project. This project will look at how enforcement of the preservation ordinance is handled, from internal process, to fines, to criminal vs. civil differences. This project will include coordination with EZEO, CAO, and other P&DS staff. LPAB role in this project will be in reviewin~ proposed code change options, and making a recommendation to City Council. Historic Preservation & Environmental Sustainability Integration Project (HPESIP) (Project Coordinator: Chris) This project includes implementation of the recently approved policy direction on window & door replacement, as well as direction on guideline revisions.

The Downtown historic district (designated in 1999) is located one block northwest of the property. While the property is not designated as a local landmazk or located in a designated historic district, because of its proximity to the Chamberlain and Downtown historic districts, comments as part of the site review process have been requested from historic preservation staff. The proposed new construction will most directly impact properties located on the south side of Walnut Street in the Chamberlain historic district. Plans show the proposed four- story neo-modernist building will be approximately 90' north of the row of historically contributing Queen Anne and Edwardian Vernaculaz houses on the south side of Walnut Street. The design for the new architecture relies for its effect on relatively unadorned surfaces and large glazed areas articulated by stoops, balconies, and deck areas. To an extent the design depends on form and materiality including the use of brick, stucco, steel and glass. In terms of mass, scale, and height the proposed building is considerably larger and than adjacent historic properties in the Chamberlain historic district. Efforts appear to have been taken to break up the mass of the south elevation of the building by stepping and setting back planes of the building. The effective street front height of the street (south) face of the building is two-stories with the facade broken into five bays ranging in width from 20' to 35'. While this pattern reflects the rhythm of storefronts in the Downtown Historic District, the scale of these bays is compazable in scale to the historic buildings on the south side of Walnut Street. A preliminary review of the proposed design indicates that that the proposed new construction will not negatively affect the character of the Chamberlain historic district. While the building is considerable lazger than anything in the district, the 90' distance from the nearest buildings and articulation of the proposed building will mitigate any adverse effect its mass and scale might have. The new construction indicates sensitivity overall context of the azea and is consistent with policy 230, Preservation of Historic and Cultural Resources of the Boulder Valley Comprehensive Plan. For more information regarding this matter, please call James Hewat at 303.4413207. Historic Preservation Comments 1605 WalnutStreet The subject property is located just north of the Chamberlain Historic District, the middle of Walnut fornung the northern boundary of this district which was designated in 1996. The Downtown historic district (designated in 1999) is located one block northwest of the property. While the property is not designated as a local landmazk or located in a designated historic district, because of its proximity to the Chamberlain and Downtown historic districts, comments as part of the site review process have been requested from historic preservation staff. The proposed new construction has the potential to directly impact properties located on the south side of Walnut Street in the Chamberlain historic district; in particular the row of historically contributing Queen Anne and Edwazdian Vernaculaz houses on the south side of Walnut and the 1907 Richardsonian-Revival First Presbyterian church located at the southwest corner of Walnut and 16`h Streets. In terms of mass, scale, and height the proposed "annex" building is considerably lazger and than the historic houses immediately south on the 1600 block of Walnut, though comparable in overall scale with rusticated First Presbyterian Church building. The design for the proposed church references the historic church with its corner tower, round arch windows, gable ends, and brick and stone materials. Efforts have been taken to break up the mass of the south elevation of the building by breaking the wall expanse into two, 2T wide bays. While this pattern reflects the rhythm of storefronts in the Downtown Historic Histrict, the width of these bays is also compatible with the historic buildings located on the south side of Walnut Street. However, at 23' in height, this one-story element does appeaz out of scale and somewhat ill-proportioned (the applicant might be attempting to match the projecting two-story bays proposed at 1655 Walnut Street). The two-story building seems unusually tal] at 40'. Staff recommends these "starefronY' elements of the building redesigned to be more traditional in scale and proportion (see Section 1.2 of the Downtown Urban Design Guidelines. Steps might be taken to create a more traditionally proportioned two-story building with a third story set back. Historic Preservation staff also suggests that the applicant consider revising the second-story fenestration to make to make it more compatible with historic commercial buildings in terms of proportion, rhythm, and glazed to wall area by referring to Section 1.2 of the Downtown Urban Design Guidelines. For more information regarding this matter, please call James Hewat at 303.441.3207. Historic preservation The wood frame Queen-Anne house located at 400 Marine Street was constructed around 7900. The 1901-02 Boulder City Directory list the house at the residence of Samuel R. Wheeler and his wife Sophia. Wheeler was the founder and minister of Boulder's Seventh Day Baptist Church after arriving from Nortonville, Kansas where he also served as a minister. A 1989 Historic Building Inventory Record completed for the property found the house to be a good example of Queen-Anne vernacular architecture with a high degree of historic integrity. The property is located in the identified potential expanded Highland Lawn historic district. Staff considers that the building would be historicaily contributing to the identified district may also be eligible for designation as a local historic landmark. Plans for the re-development of this property call for the construction of a rear addition, the "restoration" of the main portion of the existing of the house, the construction of a rear addition, and the demolition of a detached garage. Staff strongly encourages the property owner to consider submitting an application to landmark the house per Section 2.33 of the Boulder Valley Comprehensive Plan, Preservation of Historic and Cultural Resources. Designation of the building would provide the property owner with the opportunity to take advantage of a state historic preservation tax credit (20% of the project cost up to $50,000) for the restoration of the house. Sanborn map research indicates the garage at the rear of the property is older than fifty years in age. Its demolition will require submission of an application for the demolition of a non- designated building older than fifty years in age per Section 9-1 t-23 of the Boulder Revised Code to determine whether or not there is "probable cause" to consider that the building may be a historic landmark. For more information regarding this matter, please call James Hewat at 303.441.3207. 2221 Walnut, Second review Landmarks Staff recommends that an application to landmark the house per Section 2.33 of the Boulder Valley Comprehensive Plan, Preservation of Historic and Cultural Resources be a condition of site review approval. Designation of the building would provide the property owner with the opportunity to take advantage of a state historic preservation tax credit (20% of the project cost up to $50,000) for the restoration of the house. Revised drawings show windows on the east elevation of the historic house to be removed and the wall reconstructed to provide for a 1 hour-fire rating. Staff suggests that the windows be preserved, and that a 1-hour fire rated wall assembly be constructed on the inside of the buildings. This method of constructing a fire rated walls behind windows to enable the preservation of historic openings is commonly employed. Plans for the rear second-story addition show the roof of this element to rise above the height of the historic house. While the General Design Guidelines recommend that roof heights of additions be lower than the height of historic buildings to which they are constructed, the proposed connector linking the two roofs is lower, creating a visual break between the old and new portions of the house. Sanborn map research indicates the garage at the rear of the property is older than fifty years in age. Its demolition will require submission of an application for the demolition of a non-designated building older than fifty years in age per Section 9-11-23 of the Boulder Revised Code to determine whether or not there is "probable cause" to consider that the building may be a historic landmark.
