Surface Water

Culverts, Catch Basins, Pipes and Easements

Island County owns and maintains more than 4,000 culverts and nearly 2,000 catch basins, nearly all associated with county roads. Additionally, the county manages drainage easements across hundreds of properties. Island County road crews keep outfalls flowing, culverts draining, catch basins catching, and surface water managed.
