Project Description

The applicant requests Design Review and Site Plan Review approval to legalize a 51 square foot shed, a 160 square foot shipping container, a 145 square foot greenhouse, and a 292 square foot art studio, and new concrete pads on a developed lot in Forest Knolls. The 648 square feet of proposed development would result in a floor area ratio of 14 percent on the 14,192 square foot lot. The height and setback information for the proposed improvements is listed below.

The shed would reach a maximum height of 10.2 feet above surrounding grade and the exterior walls would have the following setbacks: 8 feet, 10 inches from the southwestern front property line; 15 feet, 11 inches from the northwestern side property line; 80 feet from the southeastern side property line; over 100 feet from the northeastern rear property line.

The shipping container would reach a maximum height of 7 feet, 7 inches above surrounding grade and the exterior walls would have the following setbacks: over 100 feet from the southwestern front property line; encroaches into the road right-of-way 6.72 feet beyond the northwestern side property line; 76 feet from the southeastern side property line; 9 feet from the northeastern rear property line.

The greenhouse would reach a maximum height of 13.5 feet above surrounding grade and the exterior walls would have the following setbacks: over 90 feet from the southwestern front property line; 68 feet from the northwestern side property line; 11 feet, 1 inch from the southeastern side property line; 6 feet, 5 inches from the northeastern rear property line.

The art studio would reach a maximum height of 10.7 feet above surrounding grade and the exterior walls would have the following setbacks: 70 feet from the southwestern front property line; 63 feet, 6 inches from the northwestern side property line; 9 feet from the southeastern side property line; 25 feet from the northeastern rear property line.

Design Review approval is required pursuant to Marin County Code Section 22.42.020.C because the project entails legalizing detached accessory structures that encroach into the minimum setbacks. Site Plan Review approval is required pursuant to Marin County Code Section 22.52.020.F as the project entails legalizing detached accessory structures that were constructed within the SCA on a lot subject to the SGV combining district. Additionally, Site Plan Review is required pursuant to Marin County Code Section 22.52.020.G as the project entails legalizing detached accessory structures that were constructed outside the SCA.
