NOD - Notice of Determination
Document Description
The California Department of Fish and Wildlife (CDFW) has executed Lake and Streambed Alteration Agreement number EPIMS-RIV-21903-R6, pursuant to section 1602 of the Fish and Game Code to the project applicant Paul Onufer. The Project is limited to the installation of rock slope protection (RSP; rip rap), retaining walls, and manufactures slopes to the unnamed drainage and along the streambed riparian habitat of the unnamed drainage. The unnamed drainage enters the Project site from the southwest corner through a concrete box culvert flowing northeast. The unnamed drainage continues to flow through the Project site along the southerly boundary and exists the eastern boundary of the project site over Indian Truck Trail. Impacts to the unnamed drainage will result from three construction activities at the locations within the unnamed drainage identified as Impact Area 1, 2, and 3. Impact Area 1 involves the installation of RSP (riprap) along the northern edge of the stream on the southern boundary of the Project site. 3.4 feet thick ½ ton RSP will be installed over a 1.8 feet thick no.1 backing with RSP fabric underneath. The RSP will be contoured to a 4:1 slope. Additionally, at the base on the RSP, a 6-inch-thick concrete wall will be installed to support the RSP. Impact Area 2 involves slope recontouring of the stream slope along the southeast boundary of the Project site. The stream slope will be modified to 2:1 to accommodate the development of the residential homes and fuel modification area. Impact Area 3 involves the construction of a 15-foot concrete retaining wall with privacy fencing on top along the edge of the stream. The retaining wall will be installed along the boundary streambed habitat of the unnamed drainage and within the greater development area adjacent to the street, curb, gutter, and sidewalk features.
