The applicant requests Design Review approval to construct a new 1,125 square-foot addition onto an existing 2,864 square-foot single-family residence in unincorporated San Anselmo. The 1,125 square feet of proposed development would result in a total floor area of 4,288 square feet, resulting in a floor area ratio of 9.3 percent on the 45,940 square-foot lot. The proposed building would reach a maximum height of 25 feet, 11 inches above surrounding grade and the exterior walls would have the following setbacks: ten feet, two inches from the northern front property line; 43 feet, 9 inches from the eastern rear property line; and more than 100 feet from the western front and southern side property lines. Various site improvements would also be entailed in the proposed development, including a new ten-foot tall attached trellis.
Design Review approval is required pursuant to Marin County Code Section 22.42.020 because the project will exceed 3,500 square feet in total floor area.
