Upcoming Projects

SR 169 & North Commercial Stormwater Treatment Facility
Start Date: TBD
Completion Date: TBD

Public Works staff received a Water Quality Improvement Program grant from King County in the amount of $243,643 and was able to use the funds to purchase property at the intersection of Roberts Drive and SR 169. Public Works staff is currently working to secure grant funds to install a stormwater filter vault on this property, along with the installation of storm pipe on SR 169 to capture runoff from SR 169 and the north commercial area, and convey it to the new filter vault for treatment prior to being discharged into Ginder Creek. Currently, all polluted stormwater runoff in this area discharges mostly untreated to Ginder Creek. This project would clean up the heaviest stormwater pollutant loading into local receiving waters in Black Diamond.

The Public Works Department began work on constructing the Ginder Creek Trail between Roberts Dr. (north of the library) and Morgan St. (near Ginder Creek) utilizing a Youth and Amateur Sports Grant from King County. Public Works is seeking additional funding to complete this trail. The trail will mainly be gravel except for a portion of elevated boardwalk that will be needed to cross a wetland and minimize the impact.
