Rock Armoring and Erosion Control Supply

The contract entails the supply of durable, angular riprap rock specifically designated for erosion control at culvert inlets and outlets, with the primary objective of preventing scour and preserving the structural integrity of these critical water management components. The material must meet stringent durability and angularity criteria to effectively dissipate water energy and resist displacement during high-flow events, ensuring long-term performance in high-stress environments. This work is essential for protecting infrastructure and stabilizing surrounding terrain against progressive erosion that could otherwise compromise functionality and safety. The contract is classified as a subcontract under NAICS code 327310, which corresponds to stone, clay, and glass product manufacturing, indicating that the supplied rock will be processed or quarried to meet exact engineering specifications. Performance is required in Covelo, California, within the jurisdiction of the Fish and Wildlife, Region 1 - Northern Region, Redding and Eureka, underscoring the environmental sensitivity of the location and the importance of compliance with regional ecological standards. Though the solicitation number and point of contact are unspecified, the contract was posted on June 10, 2026, and further details can be accessed via the public link provided for transparency and project tracking.
