Sweetbriar Bank Stabilization Project

The Sweetbriar Bank Stabilization Project is a forecast initiative managed by the California Regional Water Quality Control Board, Region 5 in Redding, located at 29511 Shade Avenue, Castella, California, in Shasta County. The primary objective of the project is to prevent erosion and protect a residential driveway from washing out during high-flow events. The scope of work involves the installation of rock slope protection using quarter-ton rock extending 120 feet along the bank, which will result in 0.03 acre of permanent impacts. The project is classified under NAICS code 237990. The project is exempt from California Environmental Quality Act review under section 15304 for minor alterations to land. It requires specific regulatory authorizations, including Clean Water Act Section 404 authorization from the U.S. Army Corps of Engineers under Nationwide Permit 13 and Section 401 Water Quality Certification from the Central Valley Regional Water Quality Control Board under WDID No. 5A45CR00673. Key points of contact include Senior Environmental Scientist Lynn Coster for the state agency and Gabriel Leggieri for the U.S. Army Corps of Engineers.
