Cannon Beach 7th & Oak Stormwater Outfalls Water Quality

[Cannon Beach, OR] Windsor Engineers provided analysis of a stormwater outfall located near a large dune. The outfall was called “7th & Oak”. The project was necessitated due to Oregon Parks and Recreation having concern about 5 city Outfalls. The Outfalls were built without adequate permitting and the stormwater discharge is not treated. Windsor provided alternatives analysis and cost estimates to help add treatment to the outfalls while also considering solutions to improve beach safety and reducing erosion. The state requested that the outfall be shortened to be behind the Statutory Vegetation Line. Windsor’s analysis showed this to be not feasible.
