The applicant requests Design Review approval to construct a new 2nd story 300 square foot addition onto an existing residence in Kentfield. The 3,295 square feet of proposed development would result in a floor area ratio of 31% percent on the 10,328 square foot lot. The proposed addition appears to reach a maximum height of 20 feet above surrounding grade and the exterior walls would have the following setbacks: 32 feet from the northern front property line; 80 feet from the eastern side property line; 18 feet from the western side property line; 21 feet from the southern rear property line. Various site improvements would also be entailed in the proposed development, include interior remodel.
Design Review approval is required because the applicant is proposing to exceed the 30% floor area ratio allowed by Marin County Code section 22.54.045. Marin County Code section 22.54.045 states that new development within the footprint of an existing structure floor area ratio may be increased by an amount not to exceed 35% or 300 square feet, whichever is more restrictive.
