The Briones Aqueduct Stabilization Project
NOE - Notice of Exemption
The project is limited to the maintenance, stabilization and reinforcement of a failing slope bank along San Pablo Creek that threatens 90 inch diameter public water conveyance pipeline. The entire work area is approximately 8,000 square feet including bed, bank and channel areas. Bank restoration will be performed using biotechnical bank stabilization methods such as root wad replacement, embedding tree trunks into banks for scour stability repair, installation and construction of bend-way weir and rock vanes to reduce shear stress in the riparian zone and to redirect the flow of water. The Project also includes interspersed natural boulders on the slope of the bank to provide added embankment and vegetation stabilization as well as non-erodible transitions, bio-degradable natural fiber blankets on banks and compressed planting strategies during restoration. Issuance of a Streambed Alteration Agreement, number 1600-2015-0340-R3, is pursuant to Fish and Game Code Section 1602.
This project is exempt from CEQA because it consists of emergency repairs to publicly or privately owned service facilities necessary to maintain service essential to public health, safety or welfare and requires specific actions necessary to prevent or mitigate an emergency.
