Assessor's Parcel 048-202-34
The applicant requests Design Review approval to construct a series of retaining walls that would create multiple terraces in the rear yard of a property developed with an existing single-family residence in unincorporated Mill Valley. The proposed development would result in a floor area ratio of 30 percent on the 7,508 square foot lot. The proposed retaining walls would range from 4 feet in height, to a maximum height of 7 feet above surrounding grade and would maintain the following minimum setbacks: 62 feet from the eastern front property line, 5 feet from the southern side property line, 5 feet from the northern side property line, and 5 feet from the western rear property line. Various site improvements would also be entailed in the proposed development, including an Accessory Dwelling Unit, pool, decks, play area, and an outdoor patio.
Design Review approval is required pursuant to 22.20.052 (Retaining Wall Standards) because the project entails outward facing retaining walls that are greater than four feet above surrounding grade.
