UPCOMING PROJECTS

 
stormwater treatment
 

SR 169 & North Commercial Stormwater Treatment Facility

Start Date: TBD

Completion Date: TBD

Public Works staff received a Stormwater Capacity Grant from the Department of Ecology for the design of the SR 169 & North Commercial Stormwater Treatment Facility project. The City hired Parametrix to complete the design, which is complete as of January 2015. Public Works staff is currently seeking funding for the construction of this project and received a Water Quality Improvement Project grant from King County in the amount of $243,643. The City needs up to $700,000 more to complete this project.
There is a high priority stormwater outfall at SR 169 and Roberts Drive that discharges pollutants into Ginder Creek. This project would capture stormwater runoff from the north commercial area and SR 169 and transport it down Roberts Drive to City property for treatment prior to discharge into Ginder Creek. This project would clean up the heaviest stormwater pollutant loading into local receiving waters in Black Diamond.
