Document Description
The applicant seeks approval of a Land Use Permit for the construction of a 3,855-square-foot single-family second residence with a 923-square-foot attached garage. A new driveway will be constructed to provide access from Old School Road to the new residence, and approximately 140 feet of the existing Old School Road will be widened to 20 feet. The project also includes the replacement of an existing 25-foot long, 48-inch diameter metal culvert that is within a creek with a new 60-foot long 60-inch diameter High Density Polyethylene (HDPE) pipe. The road over the new culvert will be widened to 32 feet. Grading for the project includes approximately 750 cubic yards of cut earth and approximately 100 cubic yards of fill. The land use permit application would include a tree permit for road grading and culvert replacement work that will occur within the dripline of six code-protected trees, including four oak trees ranging from 42-60 inches in diameter, a 42-inch diameter California buckeye tree, and a willow tree. The project also includes exceptions to the Public Works collect and convey requirement to allow stormwater discharge into a natural depression or swale; and an exception to allow gravel paving for the widening of Old School Road where paved roads are required.
