Stream Bank Re-contouring and Bioengineering

The contract involves reshaping and stabilizing approximately 800 linear feet of degraded stream banks in Grass Valley, California, using a combination of earthmoving and bioengineering methods to restore natural hydrologic functions and halt further erosion. The work will focus on recontouring the bank structure to reduce instability, integrate native vegetation for long-term root reinforcement, and reestablish sediment flow patterns that support healthy aquatic ecosystems. This is not a standalone project but a subcontract under the City of Grass Valley’s broader environmental restoration initiative, with work to be performed at a location identified by the ZIP code 95945. The NAICS code 237990 categorizes this effort as other heavy and civil engineering construction, indicating a specialized scope that falls outside typical road or building projects. The solicitation was posted on June 1, 2026, and performance is expected to occur in the immediate area of the degraded stream segments, with no additional set-aside or organizational type specified.
