The applicant requests Site Plan Review approval to construct a new residence on a vacant lot in San Anselmo. The development would result in a lot coverage of 21.6 percent on the 56,163 square foot lot. The proposed building footprint would have the following setbacks: 154 feet, 2 inches from the southern front property line (30 feet, 11 inches from the Sacramento Avenue right-of-way); 10 feet from the eastern side property line; 161 feet, 10 inches from the western side property line (27 feet, 11.5 inches from the Sacramento Avenue right-of-way); 89 feet, 1.5 inches from the northern rear property line.
The project entails an approximately 136-foot extension of Sacramento Avenue that will transition to an approximately 185-foot driveway, which includes a fire truck turn around, to access the residence. Included in the driveway design is a staircase that would allow for public access across the undeveloped right of way that bisects the property. Grading includes 1,248 cubic yards of excavation, 1,104 cubic yards of fill, and 114 cubic yards of import to accommodate development of the roadway extension, driveway, and residence.
Drainage will be collected and directed downhill to level spreaders, erosion control devices designed to reduce water pollution by reducing the impact of stormwater surface runoff. All trees are proposed to remain, and plantings are proposed at the base of the fire truck turnaround retaining wall.
Site Plan Review approval is required because the project entails development on a lot accessed by a paper street pursuant to Section 22.52.020.D of the Marin County Code.
Zoning: R1:B2 (Residential, Single Family, 10,000 square feet minimum lot size).
