City of Lafayette Staff Report Design Review Commission

City of Lafayette Staff Report Design Review Commission Meeting Date: January 8, 2018 Staff: Subject: Sarah Allen, Senior Planner SS14-17 Dexter & Patricia Louie, (MRA Zoning) Request for a Study Session to discuss the proposed demolition of six existing cottages and the construction of five new attached townhomes on a parcel located at 3624 Chestnut Street, APN 243-101-028. Overview A study session is an opportunity for an applicant to informally discuss a contemplated project with the Design Review Commission and receive feedback on what is presented. It is not a formal application and no action to approve or deny a specific project will be taken at the study session. At a future date, the applicant may decide to submit a formal application for Design Review and additional public notification would be provided at that time. The level of design and extent of materials is commensurate with the preliminary and informal nature of a study session. Since no formal application is filed and deemed complete, staff does does not conduct a thorough analysis of the project in light of the Lafayette Municipal Code or make a recommendation to the Commission for action. Background Staff has no record of when the building was actually constructed; however, the parcel map shows the Bickerstaff Tract was recorded in 1918, which created the subject lot. There have been no formal applications on the property, only minor maintenance and repair. The Project The project involves demolishing the existing six (6) units onsite and redeveloping with five (5) units. The plans show a 2-story building, under the 35-ft. height limit. This application will require design review because it is located in a multi-family zoning district and the project will be visible from a public vantage point pursuant to section 6-839 of the Lafayette Municipal Code (LMC). The Design Review Commission should speak to the overall organization of the site, relationship of the building to the street and the surrounding neighborhood, the schematic architecture and any aspect of the project that could affect the ability to make the findings listed below. The attached Framework for Review is also helpful in evaluating a project. Required Findings If a formal application is submitted, the hearing body must make the following findings in order to approve the project as it lies within a multi-family zoning district [ 6-275(A) LMC] Page 1 of 2

(1) The approval of the plan is in the best interest of the public health, safety and general welfare; (2) General site considerations, including site layout, open space and topography, orientation and location of buildings, vehicular access, circulation and parking, setbacks, height, walls, fences, public safety and similar elements have been designed to provide a desirable environment for the development; (3) General architectural considerations, including the character, scale and quality of the design, the architectural relationship with the site and other buildings, building materials, colors, screening of exterior appurtenances, exterior lighting and signing and similar elements have been incorporated in order to ensure the compatibility of this development with its design concept and the character of adjacent buildings; and (4) General landscape considerations, including the location, type, size, color, texture and coverage of plant materials, provisions for irrigation, maintenance and protection of landscaped areas and similar elements have been considered to ensure visual relief, to complement buildings and structures and to provide an attractive environment for the enjoyment of the public. Staff Comments The MRA zoning district is the only district that requires a floor area ratio (FAR) calculation. The allowable floor area is based on the size of the lot. In this case the lot is 11,940 sq. ft. and the FAR is.31, so the square footage permitted would be 3,701 sq. ft. Based on a preliminary review of the application materials staff finds the project may require an exception or variance to the FAR requirements outlined in the MRA zoning regulations. The applicant can request an increase of up to 0.4 FAR (or 4,776 sq. ft. in this case); however, the request is a variance application that requires review by the Planning Commission. Recommendation Provide feedback to the applicant. This is an informational item and no formal action will be taken. Attachments 1. Location Maps 2. MRA Zoning Regulations 3. Framework for Review 4.

Downtown Residential Neighborhoods The neighborhoods adjacent to the commercial areas of the downtown are part of the DSP because of their proximity to downtown services, transit, and amenities. They provide affordable housing and a variety of housing types. The aim of the DSP is to protect these neighborhoods. Figure 12. Downtown Residential Neighborhoods 50 4. DOWNTOWN CHARACTER

The Existing Context Downtown Neighborhoods Neighborhood I: Mountain View Drive / West Road. There is a mix of onestory single-family homes and multifamily townhouse developments. On the north side of West Road there are a few single-family homes and a long masonry wall separating the neighborhood from the office buildings along Mount Diablo Boulevard. On the south side and at the end of the street there are two clusters of townhouses. The small homes probably date from the 1930s, 1940s, and 1950s, and they retain the character of these years. The townhouses are from the 1980s; they reflect the style of the time with wood shingles. There are fewer trees along Mountain View Drive than along West Road, which has a number of redwood trees around the townhouses. Mountain View Drive to Brook Street is sometimes used as a Mount Diablo Boulevard bypass. There are gaps in the walkway improvements along the west side of Mountain View Drive. West Road is private with no throughtraffic, but there are walkway improvements in sections near the newer development. Neighborhood II: Brook Street / Hough Avenue. The predominant land use is smaller scale multifamily residential with townhouses and apartments dating from the 1940s through early 2000s. There are single family homes in the Walnut / Chestnut Streets area, some of which are small enough to be considered cottages. The civic use is Brook Street Park. Because the lots are small, the feel of the neighborhood is fairly dense. The density, traditional architecture, abundance of trees, narrow streets, and occasional walkways form the neighborhood s character. Most of the neighborhood has narrow residential streets and occasional gaps in the walkways. Hough Avenue and Dewing Avenue provide back door access to the Downtown Core. Neighborhood III: Carol Lane. The predominant use in this neighborhood is multifamily residential. Lafayette Highlands is a rental apartment complex off Carol Lane. There are townhouses on Marlene Drive. Both developments date from the 1960s-1970s. Along Carol Lane between the Highlands driveway and Marlene Drive, there are residential and office uses. What the DSP Proposes Downtown Neighborhoods Neighborhood I. This neighborhood will provide a medium-density townhouse residential area at a physical scale compatible with nearby residential areas. Office and retail uses will not be allowed except for home occupations. The older single-family homes will be encouraged to be maintained and offer an affordable housing option. If redevelopment were to occur by combining parcels, lower intensity multifamily uses will be appropriate as a transition between the commercial uses along Mount Diablo Boulevard and the residential uses to the south. Its natural setting and open space will be preserved. Neighborhood II. This neighborhood will offer a varied mix of housing types as well as other uses at a scale that does not detract from its residential character. It is important to preserve and promote a diversity of housing types and affordability for the downtown and community. This neighborhood is a valuable resource for making living in Lafayette more accessible, especially for young families who wish to send their children to nearby schools and for seniors who wish to be close to downtown services and amenities. The neighborhood also presents the opportunity to create housing types for residents that want to walk to stores, BART, and the Library and Learning Center while living in a small traditional neighborhood. If redevelopment were to occur by combining parcels, lower intensity multifamily uses will be appropriate. Neighborhood III. Given the age and type of existing development, it is unlikely that this neighborhood will change over the next 20 years. It should be maintained as a multifamily neighborhood with a variety of options for affordable housing. 4. DOWNTOWN CHARACTER 51

Policy 2.25 Program 2.25.1 Program 2.25.2 Program 2.25.3 Downtown Residential - Land Use. Offer a variety of affordable housing choices within easy walking distance of the downtown and BART. Neighborhood I. Amend the Zoning Ordinance to allow only the development of townhouses and single-family residences. Neighborhood II. Amend the Zoning Ordinance as necessary to promote residential development and prohibit office uses with the intent of retaining and encouraging the eclectic mix of residential types and defining the neighborhood boundaries to prevent the encroachment of non-residential uses. Neighborhood III. Maintain the current zoning since this neighborhood is built out. Policy 2.26 Policy 2.27 Downtown Residential Density. The maximum residential density is: Neighborhood I 17 units per acre Neighborhood II a portion is 17 units per acre and a portion is 35 units per acre* Neighborhood III a portion is 17 units per acre and a portion is 35 units per acre* Downtown Residential - Building Height. The maximum height is: Neighborhood I 25 feet Neighborhood II a portion is 25 feet and a portion is 35 feet Neighborhood III a portion is 25 feet and a portion is 35 feet Policy 2.28 Downtown Residential - Pedestrian Experience. Strengthen the pedestrian connections between the neighborhoods and the downtown to ensure safety and accessibility while maintaining the quiet, residential quality of these neighborhoods. *For more information, see the Zoning Ordinance. 52 4.
