The applicant has submitted Design Review and Tree Removal Permit applications requesting approval to construct a single family residence, with attached garage, retaining walls, access driveway, emergency turnaround/parking area, and car bridge (over Sorich Creek) on a vacant lot located at 308 Los Angeles Blvd in San Anselmo. The proposed project would consist of 4,306 square-feet of total building area and 3,872 square-feet of total floor area, for a floor area ratio of 5 percent on the 77,124 square-foot lot.
The proposed residence would reach a maximum height of 26 feet above natural grade and would have the following setbacks from the exterior walls: approximately 112 feet from the western front property line; 80 feet from the eastern rear property line; 11 feet, 5 inches from the southern side property line; and 6 feet, 3 inches from the northern side property line.
The proposed site improvements include the construction of a new concrete access driveway and fire truck turnaround, as well as construction of a 16-foot wide concrete vehicular bridge (over Sorich Creek). A temporary access road is proposed to be constructed over Sorich Creek while the bridge and permanent driveway are constructed. New sewer and water line extensions are proposed to be installed in the existing 20 foot utility and roadway easement that extends from Los Angeles Blvd to the project site.
The project site is a flag lot, which slopes steeply from west to east, with an average slope of 40%. The front, westernmost, portion of the lot is encumbered with an intermittent stream Sorich Creek. The area bordering Sorich Creek is characterized by mixed willow, riparian habitat. The upper, sloped, eastern portion of the property is characterized by upper riparian, coast live oak woodland habitat. Eighteen trees, classified as either “protected” or “heritage” per the Marin County Development Code, are proposed to be removed to accommodate construction of the residence and site improvements
Design Review approval is required because the project is located in a planned zoning district. A Tree Removal Permit is required because more than one “protected” tree is proposed to be removed.
