The City of SeaTac conducted an environmental review of the Des Moines Creek Basin Restoration Projects, a multi-agency effort involving the cities of SeaTac and Des Moines, the Port of Seattle, and King County. The project aims to improve water quality, reduce flooding, and restore fish habitat along Des Moines Creek by building a new detention facility, installing a high-flow bypass pipe, and maintaining low-flow water levels during dry summer months. The city's staff determined that the project does not require a full Environmental Impact Statement, as it is not expected to have a significant adverse impact on the environment.Open full document
