San Luis Obispo County updates stormwater infrastructure maps in Los Osos, Calif.
(UI) — The County of San Luis Obispo Stormwater Program is beginning a multi-year effort to update maps of stormwater drainage systems across unincorporated communities.
Starting in late January 2025, county personnel will map stormwater inlets, outlets, infiltrators, and pipes in the community of Los Osos. The work is expected to finish by April.
“The goal of this project is to capture updated, geographically correct data for the many different types of storm drainage infrastructure in our county. Each community has unique combinations of drainage structures that have been installed over many years,” said Ann Fletcher, County Stormwater Coordinator.
According to Fletcher, similar updates were completed in several communities in 2024, and the team is prepared to begin work in Los Osos.
County staff will collect data only in public rights-of-way and on county-maintained roads, excluding privately owned or operated storm drainage systems. No construction is associated with the project.
Mapping efforts will pause during bad weather to ensure personnel are available for storm and emergency response.
Residents are urged to follow posted speed limits and remain alert for workers in roadways and shoulders during the mapping process.
