Sequoia Creek and Walker Creek Culvert Replacement Design
King County Flood District awarded Normandy Park a $200,000 grant to design replacement culverts. The Flood Reduction Grant will fund preliminary design. The project will include the design of three existing culverts. in Normandy Park sized to convey 100-year flows. The culverts will be designed as fish-passable culverts or bridges. The City is currently working with an engineering consultant to prepare a feasibility study and engineering plans. Surveying and monitoring activities will take place in February 2020 along portions of the Sequoia and Walker Creeks.
