The applicant is requesting approval of a tentative map to subdivide the subject 1.50-acre parcel into two parcels. Upon dedication of approximately 0.09-acres of right of way to the County for the potential, future widening of North Jackson Way, Parcel A would have an approximately 0.46-acre gross lot area and Parcel B would have an approximately 0.95-acre gross lot area. The San Ramon Creek area within the easternmost portion of the subject property (approximately 25 percent of proposed Parcel B) is restricted from development pursuant to a recorded grant deed of development rights (4212 OR 96, recorded 1962). The proposed site improvements include an approximately 16-foot paved road within an access easement ranging between 35 feet and 39.6 feet in width for access to Parcel B from North Jackson Way, and one bio-retention area on Parcel B in order to collect storm water discharge from both resultant parcels.
There are no proposed changes to the existing residence or driveway on Parcel A. However, the applicant has requested variances to the requirements of the Single-Family Residential (R-20) zoning district for a 14-foot secondary front setback (where 20 feet is required) and for a 0.7-foot side yard (where 15 feet is required) for the existing single-family residence that will remain on Parcel A. The applicant is also requesting exceptions from the requirements of Title 9 of the County Ordinance Code related to the undergrounding of overhead utility services and to sidewalk and curb improvements along North Jackson Way.
Although not proposed as part of this project, it is anticipated that Parcel B will eventually be developed with a new single-family residence. The tentative map includes a potential location for this proposed improvement indicating that it would be able to meet all required standards of the R-20 zoning district, including setbacks. It is anticipated that the project would entail ±155 cubic yards (CYS) of net fill (± 320 CYS of cut and ±475 CYS of fill) for the future private roadway and future residential foundation pad.
The applicant also requests approval of a tree permit for project impacts to fifteen code-protected trees, including work (e.g., construction or grading) within the driplines of five valley oak trees, and the removal of ten trees including one honey locust, four eucalyptus, one black oak, two valley oaks, one Monterey pine, and one overgrown privet. The project impacts are due to the trees being located within the footprint of site improvements, poor health or condition, invasiveness, or history of the species for failure.
