Meyers Design Review (P6403)

The applicant requests Design Review approval to construct a 4,601-square-foot, multi-story addition to an existing single-family dwelling and a 2,029-square-foot, detached, single-story accessory structure (garage) on a developed lot in the unincorporated area of San Rafael. The total 5,623 square feet of proposed development would appear to result in a floor area ratio of 10 percent on the 122,892-square-foot (2.82-acre) lot, pursuant to the definition of floor area ratio in Marin County Development Code Section 22.130.030 (Definitions of Specialized Terms and Phrases). The maximum heights and minimum setbacks of the proposed improvements are detailed below.

The addition would appear to reach a maximum height of 27 feet, 4 inches above grade. It also appears to maintain minimum setbacks of 109 feet, 4 inches from the eastern front property line, 26 feet, 11 inches from the northern side property line, 83 feet, 4 inches from the southern side property line, and more than 300 feet from the western rear property line.

The garage would appear to reach a maximum height of 12 feet, 10 inches above grade. It also appears to maintain minimum setbacks of 19 feet, 3 inches from the eastern front property line, 201 feet, 2 inches from the northern side property line, 10 feet, 8 inches feet from the southern side property line, and more than 300 feet from the western rear property line.

The proposed development would also include improvements to the site and the existing single-family residence. Site improvements would consist of grading activities involving approximately 805 cubic yards of cut and 85 cubic yards of fill, as well as hardscape and landscape improvements, including the removal and installation of retaining walls, the removal and installation of ornamental plantings, and the widening and lengthening of the existing driveway. Improvements to the existing single-family residence, other than the proposed addition, would include selective changes to certain attached architectural elements and fenestration.

Design Review approval is required pursuant to Marin County Development Code Sections 22.42.020(B) and 22.54.045(F) because the proposed development would occur on a lot within a conventional zoning district (A2-B6 (Agriculture, Limited District, combined with the Minimum Lot Size “-B6” Combining District)) where the existing floor area exceeds 3,500 square feet and would include the construction of a detached accessory structure within the minimum required front and side yard setbacks applicable to the zoning district (-B6 (Minimum Lot Size “-B6” Combining District)).

Countywide Plan Designation:  AG3 (Agricultural 3 Land Use Designation with a Residential Density of 1 Unit per 1 Acre to 9 Acres)
