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.

The 4th Avenue SW curb ramp retrofit project successfully brought 14 ADA ramps into compliance.  Seven catch basins that did not meet the maintenance standards of the Stormwater Management Manual of Western Washington were also replaced.  The final overlay is scheduled for Spring 2020.
