The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2020-0150-R5, pursuant to Section 1602 of the Fish and Game Code to V1 Ranch, LLC.
Between March 2016 and November 2016, unauthorized impacts to the West Fork of the San Luis Rey River occurred when a pond was excavated upstream of an existing at-grade stream crossing without submitting Notification of Lake or Streambed Alteration to CDFW pursuant to Fish and Game Code section 1602. Portions of the excavated material were placed over the at-grade stream crossing, which widened and raised the crossing.
The project consists of remediation of the unauthorized pond and enlarged crossing to return the area to pre-project elevations and contours. The six culverts that were installed within the elevated road will be removed, and the elevated road material will be redistributed within the pond area. The project also includes improvements to the at-grade stream crossing by widening it from pre-unauthorized activities to a 12-foot wide at-grade stream crossing. The at-grade stream crossing will incorporate below-grade stream armoring consisting of un-grouted rip-rap and associated geotextile fabric.
The project will impact up to 1.32 acres of stream bed, bank, channel, and associated riparian/wetland vegetation. Permanent impacts to stream areas are limited to the installation of the at-grade road crossing and associated rip-rap armoring (0.13 acre). Temporary impacts of up to 1.19 acres include 1.10 acres of habitat restoration at the pond area and 0.09-acre area of incidental impacts surrounding the habitat restoration area. The 0.13 acre of permanent impacts and the 1.10 acres of unauthorized stream impacts will be mitigated through the purchase of 1.23 credits at a CDFW-approved mitigation bank. Impacted stream areas outside of the new armored at-grade stream crossing will be restored with native vegetation according to an approved habitat restoration plan.
