BOLINAS AVENUE STORM DRAIN IMPROVEMENTS (PHASE 2) PROJECT

The Town of Ross is implementing the Bolinas Avenue Storm Drain Improvements (Phase 2) Project to mitigate flooding at the intersection of Bolinas Avenue and Richmond Road in Marin County, California. The scope of work involves increasing the capacity of the public storm drain system by installing approximately 620 feet of 42-inch-diameter HDPE double wall Type S pipe. This new infrastructure will run from Bolinas Avenue to a new outfall on San Anselmo Creek, situated immediately downstream of the Sir Francis Drake Boulevard Bridge. The project was approved by the Town of Ross on September 11, 2025, following a CEQA environmental review that resulted in a Negative Declaration, determining that the improvements will not have a significant environmental effect. No mitigation measures or monitoring plans were adopted as part of this determination. The project is categorized under NAICS code 237110 for heavy and civil engineering construction, with Roberta Feliciano, the Planning and Building Director, serving as the primary point of contact.
