SUMMARY The subject project is being referred to the Board for review of site and design improvements for a 2,017 sq. ft. addition to an existing single family residence located on an 8.9-acre hillside lot. The project includes the addition of a 500 sq. ft. pool cabana and a 7,000 sq. ft. covered arena which were approved by the City Council in 1996 but were never constructed. The project also requires an Exception to the Planned Development Ordinance (PD1701-H) for the existing single family residence to exceed 6,500 sq. ft. as allowed in the development plan for the project. The Board’s recommendation will be forwarded to the Planning Commission for recommendation to the City Council. Based on review of the applicable design criteria, which is discussed in detail below, staff has concluded that the project adequately addresses the applicable criteria. Staff requests that the Board review this report and provide a recommendation on compliance with all pertinent design criteria. Specifically, staff asks the Board to consider the following: Site Plan • Whether an Exception to the maximum allowed size of 6,500 sq. ft. single family residence is warranted for this large, hillside designated property; Architecture • Whether the project size and design is appropriate for the project site; and • Whether the building materials and colors are compatible with the site and surrounding neighborhood. Landscaping • Whether the existing landscaping palette is appropriate for the project; and • Whether additional tree planting with native species should be required. BACKGROUND Site Description & Setting: The subject parcel is located on Lucas Valley Road, south of the Lucas Valley Road and Mount Muir Court intersection (Exhibit A: Vicinity Map). Lucas Valley Road is a County road with a 48-ft. right-of- way in this area and is improved with one lane and a bicycle lane in each direction. There are two adjoining properties. Both are large lots. The one to the north of the property contains a single family residence. The other is a County open space lot which wraps around the property along north (partial length), south and east property lines. The project site is an upsloping property with an average slope of 9.4%. Although the property does not have an average slope of 25% or over, it is considered as Hillside property since the property is designated Hillside Residential by General Plan 2020. The front 400 feet of the property is gently upsloping. From that point on, the property has a steeper upslope with the eastern portion of the property sloping more than the driveway (western) side. A long driveway is located along the western side of the property. The driveway provides access to an open arena and 3,700 sq. ft. barn located 3 towards the front of the property, and to the existing single family residence and accessory structures located towards the rear of the property. The front of the property does not contain a lot of trees whereas the steeper area in middle of the property contains a large number of trees which screen the existing development at the rear of the property. History: The existing development on the property was approved by the City Council in accord with a Planned Development Ordinance (PD1701-H) adopted for the development on August 5, 1996 (Exhibit B). The current proposal includes some new construction accessory to the residence and two structures that were approved in 1996 but were never constructed: covering of an existing 7,000 sq. ft. arena and a 500 sq. ft. cabana with bathrooms and equipment room. PROJECT DESCRIPTION Use: The applicant is proposing to add single story additions of a 268 sq. ft. crafts room, 1,214 sq. ft. theater and 535 sq. ft. covered courtyard attached to the existing 6,500 sq. ft. single family residence and a 622 sq. ft. detached garage. The proposal also includes two structures that were approved in 1996 but were never constructed: covering of an existing 7,000 sq. ft. arena and a 500 sq. ft. cabana with bathrooms and equipment room for the pool. Site Plan: The property is accessed with a long driveway off Lucas Valley Road. The proposed project would not modify the existing driveway. The proposed arena building would be located north of the existing barn in the front of the property and would maintain a front setback of 250-ft. The remaining additions except the garage are attached to the south and west of the existing residence. The proposed arena structure would have a front setback of 250 ft. The remaining additions along with the existing residence are screened from public view from Lucas Valley Road. Architecture: The proposed additions would have hip roofs and materials and colors would match the existing residence as follows: • Concrete tile roofing • Fascia and gutter painted to match existing • Cement plaster siding to match existing • Dual pane, Low E windows, prefinished aluminum clad window frames, frames to match existing • Wrought iron hand and guardrail at outside access to crafts room • Wrought iron security gate Landscaping: None proposed. Lighting: No external lighting is proposed at this time. Grading/Drainage: Only fine grading is proposed to prepare building pads. Any Increase in drainage due to new additions would be added to the existing drainage pattern. ANALYSIS General Plan 2020 Consistency: The property is designated Hillside Residential under the General Plan 2020. A single family residence is a permitted use under the Hillside Residential designation. The General Plan 2020 contains a number of design related policies. These policies are implemented through various provisions of the Zoning Ordinance, Planned Development Ordinance (PD1701-H) and Hillside Design Guidelines, which are established to ensure proper hillside design of homes on lots with an average slope greater than 25%. Compliance with the Zoning standards and Hillside Design Guidelines would assure development 4 that is consistent with the property’s hillside designation and related policies. Pertinent design criteria are identified and discussed below. Zoning Ordinance Consistency: Planned District (1701-H) As indicated in the Site Development Summary table, the proposed residence complies with the development standards for building height, setbacks, lot coverage and parking under the PD1701-H zoning district. However, it does not comply with the development standard regarding maximum allowed floor area for a single family residence on the property. According to the PD1701-H subsection J. Additions/Modifications of Section II. Development Standards, an Exception would be required for the proposed 8,517 sq. ft. residence. The two other proposed structures (a 500 sq. ft. pool cabana and covering of a 7,000 arena) were already approved in 1996. According to SRMC 14.12.040 Exceptions to Property Development Standards, approval of an Exception to the maximum 6,500 sq. ft. allowed for the single family residence would require the following findings: A. The project design alternative meets the stated objectives of the hillside design guidelines to preserve 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 above findings can be made by the City Council, upon the recommendation of the Design Review Board and the Planning Commission, when the applicant has demonstrated that the proposed design carries out the objectives of this chapter. Staff believes the proposed project carries out the objectives of hillside development in that the proposed project would provide a lot coverage of 5.38% where 20% is allowed, maintain the existing natural state of 85.3% where 85% is required, protect significant trees and the main project would not be not visible from public right of way. Staff is requesting the Board’s direction on whether the requested Exception to the maximum allowed 6,500 sq. ft. single family residence is warranted; Chapter 12 - Hillside Development Overlay District The PD1701-H zoning district for the property establishes all other development standards of Chapter 12, except gross building square footage, stepback height and Ridgeline Development. The project is consistent with Chapter 12 of the Zoning Ordinance in terms of stepback height and Ridgeline Development. Consistency with gross building square footage criteria is discussed above. The PD1701-H zoning establishes the single family residence size to be a maximum of 6,500 sq. ft. unless an exception is granted by the City Council consistent with Hillside Design Guidelines. Chapter 25 Environmental and Design Review Permits The project is subject to the provisions of Chapter 25 (Section 14.25.030) that requires: • Shadow diagram if deemed necessary to evaluate potential shading of adjacent properties; • Story poles reflecting the proposed height of the structure(s) if needed to evaluate project impacts. The proposed project maintains large setbacks (front 250 ft., sides 20 ft./225 ft. and rear 55 ft.) and no structures on the adjoining properties are located in the vicinity of the project area. Clearly the project would not impact active recreational areas in the rear and/or side yards of adjacent properties. Therefore, a shadow diagram was not required for this project. 5 Pursuant to SRMC14.25.030.C, story poles reflecting the proposed height of the structure(s) may required if needed to evaluate project impacts. The proposed additions to the existing residence have been designed with materials, finish, colors and height to become part of the existing residence. The proposed project is screened from offsite views. Therefore, story poles were not required for the project. The project is consistent with design criteria of Chapter 25 of the Zoning Ordinance in that the project design, including its building scale, materials and colors, is consistent with the existing residence. Due to the rural nature of the area, there is no neighborhood development to compare the proposed project with. San Rafael Design Guidelines: As discussed above, the project is generally consistent with the San Rafael Residential Design Guidelines criteria regarding building design, building scale, building height, front landscaping, roof shapes, windows, driveways and parking areas, and lighting. Hillside Design Guidelines: The proposed project provides a gross building square footage of 21,439 sq. ft. as follows: Single Family Residence: 8,517 sq. ft. [(25%+9.4%) x 387,684 sq. ft. (lot area)] = 133,363 sq. ft. (subject to a maximum of 6,500 sq. ft.) Accessory structures: A total 12,300 sq. ft. approved for four structures in 1996. Out of the four approved accessory structures, 7,000 sq. ft. covered arena and 500 sq. ft. pool cabana with bathrooms were not constructed, are part of this project. The project proposes a maximum building height of 24 ft. with four covered parking spaces. Existing and proposed natural state is 85.3%. The Hillside Design Guidelines Checklist prepared for this project is attached (Exhibit C). The project complies with maximum building height, required natural state, stepback height, preservation of significant trees, hillside grading and drainage, driveway and parking design, reduction of building bulk, hillside architectural character and site lighting. However, as stated earlier the project does not comply with the maximum allowed 6,500 sq. ft. for a single family residence. NEIGHBORHOOD CORRESPONDENCE A courtesy notice for the Design Review Board meeting was mailed to all property owners and occupants within a radius of 300 feet of the subject property within 15 days prior to the Board’s meeting. A public notice sign was posted in front of the subject property. Staff has not received any phone calls or letters regarding this project. CONCLUSION Staff believes the requested Exception from the maximum allowed size of 6,500 sq. ft. for a single family residence on this property may be justified. Staff requests Board’s direction on the points specified in the Summary section. EXHIBITS A. Vicinity Map B. Planned Development (PD1701-H) C.
