228th Ave. SE/224th Ave. SE/SE 296th St. Chip Seal
Start Date: Summer 2018
Completion Date: September 2018

The Public Works Department received a grant from the State Transportation Improvement Board (TIB) for $98,759 to complete a chip seal on 228th Ave. SE/224th Ave. SE/SE 296th St. between SE 312th St. and SE 296th St. This work will tie into the chip seal that King County did last summer on the Lake Sawyer Road south of SE 312th St. Prior to the chip seal work beginning, the City is soliciting bids to do some preliminary patching along this stretch of roadway. This bid will also improve portions of shoulder along Roberts Dr. between Morgan St. and 3rd Ave. The preliminary patching will occur this Spring.

 

 

 

 

     
     
   

 

     
 
     

UPCOMING PROJECTS

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 approximately $676,357.00 more to complete this project.

The remaining $676,357 for completion of this project are on the Department of Ecology’s final offer list for a grant.
This project would capture stormwater runoff from the north commercial area and SR 169 and treat it prior to discharge into Ginder Creek. This project would clean up the heaviest stormwater pollutant loading into local receiving waters in Black Diamond.

Covington Creek Culvert Replacement

Start Date: TBD
Completion Date: TBD
The Public Works Department received a Flood Reduction Grant from King County for the design work for the Covington Creek Culvert Replacement project. Design for the replacement of the three culverts at the outlet of Lake Sawyer into Covington Creek (under 224th Avenue SE) was originally slated to be a box culvert, but due to the profile of the road and how the culverts cross the road, it was determined that a bridge would be a better solution. The City's consultant on this project, Parametrix, shifted design to focus on a bridge in lieu of a box culvert. More funds will be needed to complete the design of this project. Public Works staff is procuring other grant funding for the remaining design costs and for construction of this project, which are estimated at $1.5 million.

Public Works staff completed the work for the decommissioning of the old sewer treatment plant. Staff worked with the Department of Ecology (DOE) for permitting and site review, including site visits from DOE staff. Work included removing biosolids from the lagoon in order to formally decommission the plant. This site was in service from the mid-1980s to 1991 when the City connected to the King County sewer system. This lagoon has sat unused and dormant since 1991.
