The project is limited to the subdivision of one (1) 10-acre parcel into four (4) 2.5-acre parcels, the development of one (1) single-family home on each 2.5-acre parcel, the construction of a private road for ingress and egress, and the installation of 3 culvert structures. Grading is estimated to encompass 5.5 acres, including approximately 740 cubic yards of native soil to be excavated to a depth of approximately one foot and approximately 1,894 cubic yards or less of material to be filled. Road improvements will consist of extending 16 feet of pavement from the existing road edge and installing a 6-foot-wide asphalt path using approximately 14 cubic yards of base rock and 3.7 cubic yards of asphalt. Four (4) native Valley Oak trees, one (1) non-native eucalyptus tree and a cluster of non-native trees located along 34th Street will be removed as a result of public street improvements. Drainage swales of varying widths will be constructed on the project site totaling approximately 1,319 linear feet. An approximately 5-foot-wide roadside drainage swale will be constructed parallel to the west side of 34th Street. Additionally, an approximately 53.3-linear-foot by 10-foot wide drainage swale, a 30-linear-foot 12-inch culvert, and a 91- linear-foot by 10-foot-wide swale will be constructed to direct flows from the roadside drainage swale to a
larger drainage swale on the north side of the private road. Approximately .31 acre of swale will be created as a result of the project. Two new driveway crossings will be installed to provide access to the associated houses and maintain flow capability through the drainage swale. Both crossings will consist of 4 parallel 18-inch corrugated metal pipes with reinforced concrete and flared end sections. The first
crossing structure will be approximately 25.7 linear feet long and the second 28.6 linear feet long. Two feet of Rock Slope Protection (RSP) will be placed on each end of the new culverts.
