Project Description

The applicant requests Design Review approval to replace an existing 1,924 square foot two-story residence and 54 square foot accessory structure and construct a new two-story 3,357 square foot residence in the Tamalpais Valley area. The proposed development would consist of 3,357 square-feet of total building area and 3,004 square-feet of total floor area, which would result in a floor area ratio of 25.9 percent on the 11,554 square-foot lot. The residence would reach a maximum height of 26 feet and 9 inches above existing grade and the exterior walls will have the following setbacks: 25 feet from the western front property line; 24 feet from the northern side property line; 14 feet from the southern side property line; and 36 feet from the eastern rear property line. The exterior materials include grey stained vertical siding, doors and windows trimmed in dark bronze, and grey Versico roofing. Various site improvements are also entailed in the approved development, including replacement of the existing septic system and undergrounding of utilities.

Design Review approval is required pursuant to Marin County Code Section 22.42.020.D because the property is less than the minimum lot size due to its steep slope.

Zoning: R1-B3 (Single-Family Residential, 20,000 square foot minimum lot area)
Countywide Plan Designation: SF4 (Single-family, 1-2 units/acre)
