The California Department of Fish and Wildlife (CDFW) has executed Lake and Streambed Alteration Agreement (EPIMS-CCA-49733-R3), pursuant to Fish and Game Code section 1602, the project Applicant, Deidre Castillo.
The project proposes to restore the reach of Laguna Creek at the Project Location with a natural stream and habitat enhancements for California red-legged frog.

Project activities are limited to clearing of approximately 2.60 acres of vegetation; removal of 39 riparian trees; diversion of water around the work area; excavation and removal of the existing culvert; excavation and removal of an existing sewer pipeline or filling of the pipeline with cement slurry to abandon it in place; installation of a sewer pipeline along a new alignment within the project site; demolition of the existing spillway and replacement with natural materials; excavation and grading to construct the new channel; installation of planted rock slope protection and boulders within the channel; installation of a new arch culvert; and on-site restoration, including installation of native riparian tree plantings.
