Document Description
The applicant is requesting approval of a vesting tentative map for a minor subdivision application that would subdivide the subject 15.54-acre parcel into two parcels. Parcel “A” and Parcel “B” would each have a lot area of 7.77 acres. Access would be from Bixler Road through a shared 20-foot gravel road within a 30-foot access easement, with 20-foot radii curb returns. The first 50 feet of the access road would be paved. The application includes a request for a tree permit for project impacts to twenty code-protected trees, including nineteen river red gum (Eucalyptus camaldulensis) trees and one Aleppo pine (Pinus halepensis). It is proposed the trees be removed due to being located within the footprint of site improvements, poor health, or failure. The applicant is also requesting exceptions from the requirements of Title 9 of the County Ordinance Code relative to the widening of Bixler Road, the undergrounding of overhead utility services, and the collect and convey provisions relative to stormwater runoff. Although not proposed as part of this project, it is anticipated that each parcel will eventually be developed with a new single-family residence, barn, and septic system. Water would be provided by two existing domestic water wells that were permitted by the Contra Costa Environmental Health Division in 2019. Three 3,000-gallon water tanks for each resulting lot are proposed to satisfy fire safety requirements of the East Contra Costa Fire Protection District (ECCFPD). The vesting tentative map includes locations for these proposed and existing improvements. In addition, a grading permit will be required for the import of ±8,550 cubic yards (CYS) of fill (Parcel A ± 4,450 CYS; Parcel B ±4,100 CYS); for future residential foundation pads.
