Document Description
The California Department of Fish and Wildlife (CDFW) has executed Streambed
Alteration Agreement number 1600-2018-0329-R2, pursuant to section 1602 of the Fish and Game Code to the project Applicant, Westpark LR, LLC (Permittee) as represented by Jeff Jones.
The project is limited to the realignment of two unnamed seasonal swales which are tributary to Pleasant Grove Creek. The southern swale will be routed east around the future development. The northern swale will also be routed to the east and will require the installation of a culvert to accommodate a secondary access point to the development. Other than the installation of the culvert, the work required to realign both swales will be similar. All work will occur during the dry season when the existing swales are dry. No dewatering will be necessary. The realigned swales will be constructed using a backhoe and loader. The bank of the new swales will be contoured and compacted, with a slope not to exceed 2:1 (horizontal:vertical). A water truck may be used in order to control dust during construction. The realigned swales will be hydroseeded with a native seed mix. Once the realigned swales have been constructed, they will be tied into the existing swale at the upstream and downstream ends. The abandoned swales will be backfilled with native material, compacted, and standard erosion control best management practices will be utilized to stabilize the soil. The culvert required for the northern swale realignment will consist of a 48-inch corrugated metal pipe (CMP), which will extend approximately 140 linear feet to accommodate the road crossing. The CMP will be flared on the upstream and downstream ends. Approximately 50 linear feet of rock slope protection ( 18-inch+) will be installed along the bank at the downstream end of the CMP in order to prevent erosion. Three blue oaks will be removed as a result of the project.
