Document Description
Request for a Planned Development (PD) Permit for the construction of a new single-family dwelling and accessory structures in the Scenic Resource Protection Overlay Zone. The permit would authorize construction of (1) a one-story single-family dwelling with an attached four-car garage totaling 15,784 sq. ft.; (2) an accessory dwelling unit of 1,799 sq. ft.; (3) a detached four-car garage of 1,272 sq. ft; and (4) a swimming pool. The permit would also authorize the demolition of a 2,592 sq. ft. structure that is not considered of historic or cultural interest and the removal of one protected Italian stone pine. The dwelling and accessory structures will cover 0.49 acres of a 20.75-acre lot. In addition to the structural improvements, this PD Permit will also authorize grading, landscaping, installation of drainage improvements, and fuel modification. Grading will be limited to over-excavation and re-compaction of the existing building pad. Landscaping will include the planting of 58 trees as well as shrubs and vines. Groundcover will include 14,890 sq. ft. of artificial turf, 7,050 sq. ft. of ornamental planting, and 26,950 sq. ft. of native planting. Fuel modification will occur within 100 feet of proposed structures and will cover an area of approximately 3.87 acres. All drainage from the new development will be directed to a box planter and any overflow will be conveyed to an underground retention system, both to be located in the landscaped area. Access to the proposed dwelling will be by way of an existing paved driveway that extends one-quarter (0.25) mile from White Stallion Road to the building pad. White Stallion Road, a paved private loop road, intersects with Potrero Road, a County-maintained arterial road, 0.36 miles west and 0.38 miles east of the project site. Potable water will be supplied by California-American Water Company. Wastewater will be disposed of using an on-site wastewater treatment system comprised of a septic tank, secondary treatment system, and two 40-foot-deep seepage pits.
