SUMMARY The project site cons,i§ts of a 4,OQP square foot re§Jdentialbuilding (two units) emq a 300 sfgarage located on thg"fi'orttlside of Laurel Placi((see Exnfbit 1-Vicihfty Map, 'and EXhib'fl'''2: 'Street eTevation'i"" photo). The subject project is being referred to the Board for review of site and design improvements associated with the demolition of the existing 8' tall stone retaining wall. The project proposes to replace the wall with a three car garage (600 square feet), a new retaining wall (ranging between 8' and 11' in height) and a 9'6" tall entry gate, all within the required 15 foot front yard setback. The proposed project triggers the following entitlements: 1, Retaining walls over 4 feet in height on a hillside property requires Design Review Board (DRB) review, pursuant to San Rafael Municipal Code Section 14,16.140.A.b. 2, The project is a hillside property, with a maximum gross building square footage of 3,667 sf, per Zoning Ordinance Section 14, 12.030.D Hillside Development Overlay District. The existing gross building square footage on the project site is 4,300 sf (house plus garage), and already exceeds the maximum gross building square footage allowed, The proposed replacement of the existing 300 sf garage with a 600 sf garage would further exceed the maximum gross building square footage on site by a total of 933 sf. As such, the proposed project would require approval of an Exception to the Hillside Development standards. Pursuant to Sl;!ction 14.12.040,Exceptions to the hillside development standards must be reviewed by the City Council with recommendations from the Design Review Board and Planning Commission, As such, the Board's recommendation will be forwarded to the Planning Commission, and on to the City Council for final review and decision. 3, The proposed project requires grading of approximately 350 cu.yds. of cut/fill. Grading in excess of 50 cu,yds, of cuUfili requires an Environmental and Design Review Permit 4, The project as proposed would also require Variances to the property development standards due to the following: 1) accessory structure (garage) located within the 15 foot front setback; 2) accessory structure located within the required 3' foot side yard setback; 3) non-conformance with the required 20 foot driveway setback; and 3) proposed 9'6" tall entry gate in excess of the 8.5 foot maximum height allowed. . . The house at 248 Laurel Place is listed in the 1986 San Rafael Historical/Architectural Survey as a "good" example of a local historic resource in San Rafael. However, the home is not listed on the State or National Historic Register of Historic Places, The applicant, Laura Ackley , a qualified architectural historian by profession, authored and submitted a Historic Resource Report with an analysiS of the potential impact from the proposed project on the historic resource. Page 13 of the report concluded that the proposed project "will not detract from the historic character of the property." The report is included with the project plans as part of the DRB packet Based on review of the applicable design criteria, which is discussed in detail below, staff is generally supportive of the project, including the Exception to the gross building square footage, as the new garage will provide additional parking on site. However, the proposed three car garage would increase height and bulk along the streetscape, This massing could be reduced if the garage were designed as a two car garage, possibly with one uncovered parking space, Staff requests that the Boarc:j review this report anc;l provide a recommendation on compliance with all pertinent design criteria, Specifically, staff asks the Board to consider the following: Architecture • Design and height of the proposed 4' tall stone posts along the garage fac;:ade • Appropriateness of the height of proposed garage • Appropriateness of the proposed 9'6" tall new entry gate 2 . Landscaping .!,,~' • Choice of planting plan for garage roof garden • Choice of material for retaining wall surface Parking • Appropriateness of the proposed three car garage. BACKGROUND Site Description & Setting: The project site is a hillside property (33.84% average cross slope) and is developed with two units. The site is located in an R5 (Single Family Residential) zone but prior to 1992, the property was located in an R3 (Multi-Family Zoning District). As such, the City determined in 2013 that the existing site was a two unit "duplex" and is "legal and conforming". The neighborhood character along the south side of Laurel Place in the vicinity of the project site is a combination of traditional single family style homes with driveways and garages at grade (no retaining walls). However, on the uphill side (north side) there are two properties with garages similar to the project site (300 Laurel Place and 320 Laurel Place), as well as several other properties with retaining walls and garages built to the property line without a roof. deck. . Due to the danger of the retaining wall failing, the Public Works Department closed the sjdewalk jn front of the property in April 2017 and the property owner was cited by the Building Department to repair the wall as quickly as possible. PROJECT DESCRIPTION Use: No change to the existing house is proposed. The proposed project would demolish the existing garage, retaining wall and entry gate at the front of the property and construct a new three car garage cut into the front hillside, a new retaining wall and a new entry gate to access the existing at grade stairs along the side yard. Site Plan: The project proposes to build a 600 sf (20' x 30') three-car garage to replace the existing 300 sf (20' x 15') garage. The current garage has a zero setback on the front and side property line. The new garage would extend approximately 30 feet along the front property line (See Plan Sheet Ai) and be setback 2 feet from the front property line and 1.5 feet from the east side property line. The garage would be topped with a 3' high wrought iron guard rail and 4' tall stone posts. A new retaining wall would extend an additional 18 feet along the property to the west of the new garage, between the garage and the new 9'6" tall entry gate (see Sheet A3). The retaining wall would range in height from 8' to ii' and is designed to be setback 6.5' from the front property line. The proposed new entry gate would also have a wrought iron design and stone posts. Architecture: The proposed new garage and retaining wall will be re-faced with the existing bluestone salvaged from the retaining wall demolition. According to Page 11 of the Historic Resource Report submitted, the proposed 3 bay garage door design is "in keeping with historic 1907-1924 modes, when the original was built, and will replace the missing original doors. See Exhibit 3 (Color and Materials Board). Landscaping: The project proposes a landscaped 'green roof' above the new garage, and also new landscaping in the front yard (see Plan Sheet L 1.0). One large shrub is proposed to be removed from the project site. No trees are proposed to be removed from the site. 3 GradinglDrainage: .The project estimates approximately 350 cu.yds. of cut/fill would be required to excavate the retaining wall area. The applicant submitted a letter from the project's geotechnical ,'.. engineer indicating the project can b~i'constructed as proposed. However, the City's,Department of Public Works has reviewed the projeCt design and has indicated that additional follow-up review will be required for the garage grading and drainage on site. The project has been cleared to move forward to the Board due to the inherent danger of the failing retaining wall. However, staff has informed the applicant that if future engineering recommendations changes the height of the retaining wall , or the garage design this may trigger additional design review. ANALYSIS General Plan 2020 Consistency: The General Plan Land Use Designation for the project site is Low Density Residential (LDR). No changes to the eXisting home on site are proposed . The proposed project is consistent with the. General Plan policies with regard to LU-23 (Land Use) in the LDR Land Use category. Other General Plan Policies applicable are listed below: • NH-4 (Improve Property Maintenance): Require owners to maintain their properties on good condition and appearance and to eliminate unsafe and unhealthy conditions. The proposed project would repair a hazardous and failing retaining wall. • CD-4 (Historic Resources): Recognize, preserve and enhance the City's historic resources. Whiie the home at 248 Laurel is not listed on a State or National Historic Register, it does appear on the 1986 San Rafael Historical/Architectural Survey as a "good" example of a historic resource in San Rafael. The repair of the failing retaining wall will help preserve the historic integrity of the residential home on the site. The proposed . project entails a complete change to the front elevation of the property. Staff has worked with the applicant and is generally supportive of the proposed project, and determined that the changes are general!y consistent with the General Plan 2020 policies. However, staff does recognize that the proposed exterior change to the fac;:ade will add height and bulk to the street frontage. Staff analysis of the proposed changes will be discussed below as part of the Chapter 25 Design Review Criteria. Zoning Ordinance Consistency: The proposed project would demolish the existing garage and failing retaining wall. The existing entry gate was built without permits and therefore is not considered to be legal. The proposed project is subject to Chapter 14.04.020 Base Dtstrict Regulations for the R5 (Single Family Residential) Zoning District, Chapter 14.16 (Site and Use Regulations), and Chapter 18 (Parking). The project is over 250/0 slope and is therefore also subject to Hillside Design Guidelines (Chapter 14.12). Staff has determined that the project will comply with the hillside property development standards pursuant to Section 14.12.030, except as it pertains to the maximum gross building square footage. The site exceeds the maximum and will require City Council approval, with the recommendation of the Design Review Board and Planning Commission. Chapter 14.04.020 (Single Family Residential. R5 Zoning) The existing garage and retaining wall have a zero setback to the property line. The project proposes to construct a new three car garage within the 15' front setback of the property. Staff comment: While the proposed garage would be setback 2' from the front property line, the project does not comply with the following regUlations : 1) 20 ' driveway setback from the property line; and 2) accessory structure (garage) located within the 15' required front setback. As such, the 4 proposed project will require approval of a Variance. Staff typically supports similar front setback Variances for garages on hillside properties in order to reduce grading. Chapter 14.12 (Hillside Development Overlay) The proposed project is subject to a maximum allowable gross building square footage of 3,667 sf, pursuant to Section 14.12.040.0. Staff comment: The existing site has a gross building square footage of 4,300 sf and already exceeds the maximum allowed. The proposed new 600 sf foot garage would further exceed this limit by increasing the gross building square footage on site from 4,300 sf to 4,600 sf. This would require City Council approval of an Exception to the Hillside Property Development standards with recommendations from the Design Review Board and Planning Commission. Section 14.12.040 stipulates that Exceptions to the standard can be approved ·when the applicant has demonstrated that alternative design concepts carry out the objectives of this chapter and are consistent wiih the general plan based on the following criteria"; . A. The project design alternative meets the stated objectives of the hillside design guidelines to preseNe the inherent characteristics of hillside sites, display sensitivity to the natural hillside setting and compatibility with nearby hillside neighborhoods, and maintain a strong relationship to the natural setting; and B. Alternative design solutions which minimize grading, retain more of the project site in its natural state, minimize visual impacts, protect significant trees, or protect natural resources result in a demonstrably superior project with greater sensitivity to the natural setting and compatibility with and sensitivity to nearby structures. The applicant has stated that they desire to bring the property up to current code for parking. Adding a three car garage would add two covered additional parking spaces on site, getting closer to the required parking of 4 spaces on site (2 covered, 2 uncovered) for the existing 6 bedroom unit and 1 bedroom unit. However, the three car garage does increase mass and bulk along Laurel Place. Staff requests the Board input on whether they can support an Exception to the hillside standard for gross building square footage . . Chapter 14.16.020 (Accessory Structures) The proposed new three car garage is defined as an 'accessory structure", and is located within the required 15' front yard setback as well as within the required 3' side yard setback (for accessory structures over 120 sf). In addition, the height of the garage exceeds the 15' height limit, as measured from "grade to roof peak". Staff comment: The design of the garage with the multiple stone posts along the front facade would be included in the height measurement, and they add an additional 4' to the 14' 7" garage height as shown on Pian Sheet A3. In addition, despite being setback, the structure does encroaches into the front and side setbacks. As such, Variance approvals are required. The proposed guard railing is required per Building Code for safety and staff supports the wrought iron material. However, the design does create more mass than the existing wall. Staff requests the Board input on: • Design of the proposed stone posts along the garage facade • Appropriateness of the height of the new garage 5 Chapter 14.16.140 (Fences and Walls) The proposed retaining wall measure's between 8' and 11' in height along the Laurel Place frontage. Pursuant to Zoning Ordinance Section 14.16.140.A.1.b, retaining walls over 4' in height on ' hillside properties are not permitted except when recommended by the Design Review Board to minimize grading andlor tree removal. The proposed retaining wall ranges from 8' to 11' in height.· The . proposed new 9' 6" entry gate (as measured to the top of the stone pillars) also exceeds the 8.5'. height limit for "minor decorative entryways such as a trellis arch or laUice arch" (Section 14.16.140.A.1.d}. Staff comment: The existing retaining wall measures 8' in height. The applicant's project engineer has indicated that the project can be constructed as designed. However, The City's Public Works department has only been able to conduct a preliminary review of the project materials, and has asked for additional information on drainage and driveway slopes. The applicant has requested multiple time extensions for the re-submittal, and was unable to provide the additional information. At this point, the wall is in danger of imminent failure and the City determined that DRB review should proceed. DPW determined the additional engineering and drainage information can be submitted and reviewed with the building permit. It is not clear at this time whether the wall could be reduced in height without compromising the engineering principles. Staff supports the portion of the retaining wall setback 6.5' setback from the front property line. The height of the proposed entry gate could possibly be lower if the posts werEllower in height. Staff requests the Board's comment on: • Retaining wall height and setback • Appropriateness of the height for the new entry gate Chapter 18: Parking The project site has a one car garage. The current code requirement for the property would be 2 covered spaces and 2 uncovered spaces. Staff comment: The project site is considered legal and conforming and is therefore not required to upgrade the parking on site to meet the parking requirement. Staff supports the additional parking, but must also balance the need for off-street parking with the introduction of additional bulk and mass along Laurel Place. There is no parking on the north side of Laurel Place so there will be no loss'in on- street parking. Staff requests the Board's comment on the size of the proposed new garage. Chapter 25 -Environmental and Design Review Permit The project proposes to construct a new three car garage with a 2' front setback from the property line, a new retaining wall with a 6.5' setback from the front property line, and a new front entry gate with a zero setback from the front property line. Staff comments: Chapter 25 states that development should be harmoniously integrated in relation to both the specific site design and the architecture in the vicinity in terms of colors and materials, scale and building design. Specific architectural design considerations include, but are not limited to the following: » Creation of interest in the building elevation » Provision of a sense of entry » Materials and colors should be consistent with the surrounding area ~ Landscaping The project is generally consistent with the design criteria of Section 14.25.050 of the Zoning Ordinance in that: 1) the proposed garage doors are typical of garage doors in the vicinity; 2) the proposed materials and colors are compatible with the existing surroundings, and re-uses the historic 6 stone materials for the new retaining wall ; 3) landscaping would be added to the site in the form of a "green roof' on the garage roof and front yard landscaping; and 4) the proposed entry gate would re- ." create the original stone pillar entry design. The applicant has taken time to consider the above listed design criteria in the proposed exterior design. The originally submitted design with a recessed entry court w ith trash enclosure and a taller entry gate was revised based on staff recommendations . Staff generally supports the proposed project and determined that the design is largely in keeping with the Chapter 25 Design Guideliries , but staff does request the Board's comment on the mass and bulk of the new garage structure. NEIGHBORHOOD CORRESPONDENCE Staff received no comments in response to the Notice of Public hearing mailed to owners and occupants on May 19, 2017. CONCLUSION To summarize , the proposed project would require Variance approval for the following: 1) 20 ' driveway setback for garages . . 2) Accessory structure located in the required 15' front yard setback. 3) Accessory structure located within the 3' side yard setback. 4) Accessory structure exceeding the 15' height limit. 5) Entry gate exceeding the 8.5' height limit. Staff supports the concept of addit ional off-street parking for the site and repair of the retaining walls. Staff has determined that Findings to support the proposed Variance for a new garage can be made as the proposed project represents an upgrade that wou ld add parking to a site that is under-parked for the resident ial units on site. The location of the new garage is setback 2 ' feet from the front property line , which is an improvement to the existing zero front setback.· The side yard setback of 1.5 ' is also an improvement on the existing zero setback to the east side property line . The applicant has indicated that the proposed three car garage could not be moved further to the west due to lack of sufficient clearance for the existing stairs leading to the residence. HO\i\(ever , staff recommends possibly designing uncovered parking for at least one space as a possible solution to reduce mass and bulk. The applicant has stated that the height of the new retaining wall and height of the garage was determined based on engineering requirements. Staff is concerned that the design of the 4 ' stone post on the garage fayade add more bulk and mass along the street frontage. This also applies to the height of the stone pillars on the proposed entry gate. Staff requests that the Board comment on the following: Architecture • Design of the proposed stone posts along the garage fayade • Appropriateness of the height of the {jarage • Appropriateness of the 9'6" height for the new entry gate Landscaping • Choice of planting plan for garage roof garden • Choice of material for retaining wall surface Parking • Appropriateness of the proposed three car garage. 7 EXHIBITS 1.
