The National Park Service requires a contractor for a long-term channel stabilization project at Golden Gate National Recreation Area, involving the removal of a rusted culvert and construction of rock features to repair damage from a 2015 blowout. In-channel work is restricted to between June 15 and October 15, 2026. The project includes stabilizing a 250-foot creek section and a 75-foot adjacent gully, with rock slope protection needing to be purchased and transported to the site. Performance of services will occur at the Conlon Creek tributary to Redwood Creek within the Golden Gate National Recreation Area. This acquisition is a total small business set-aside under NAICS 237990, with a firm-fixed-price contract to be awarded based on best value.
