Description
More intense heavy rain events can create widespread challenges for managing stormwater runoff and flooding. King County will continue work on developing a standard methodology for climate resilient stormwater facility design (including Green Stormwater Infrastructure, leveraging King County work with the Washington Department of Ecology to update statewide stormwater design software to include updated bias corrected climate change projections. This includes updating hydrologic and hydraulic watershed models that will serve as tools for developing a climate change methodology and guidance for King County stormwater management. Once developed, the County will utilize the results of this work to develop King County stormwater facility design guidance and standards, where appropriate.
