The applicant requests Design Review approval for the construction of a 7-foot-tall retaining wall in the right-of-way of Tennessee Avenue and a Tree Removal Permit for the removal of four protected trees and two heritage trees. The applicant also requests Accessory Dwelling Unit Permit approval to construct a new 1,196 square foot accessory dwelling unit on a developed lot in Mill Valley. The existing 1,380 square feet residence, plus the proposed 1,196 square foot accessory dwelling unit would result in a floor area ratio of 12.5 percent on the 20,473 square foot lot. The proposed building would reach a maximum height of 15 feet above surrounding grade and the exterior walls would have the following setbacks: more than 80 feet from the northern front property line; 26 feet from the eastern side property line; 24 feet 8 inches from the western side property line; 45 feet 10 inches from the southern rear property line.
Design Review is required pursuant to Marin County Code section 22.20.052. A Tree Removal Permit is required because more than two protected tree are proposed to be removed. Accessory Dwelling Unit Permit approval is required because the project is for an accessory dwelling unit over 800 square feet.
