Staff document (portion)

Background

Culverts L80 and L90 are immediately downstream of a collapsed private culvert that exists on private property on the west side of SR 104, north of NE 185th Street.

Immediately north of the collapsed culvert is a culvert which passes underneath SR 104, identified as L100. Culvert L100 is the responsibility of WSDOT and they are currently designing a replacement as this culvert is included in a list of culverts with fish passage shortcomings WSDOT is required to replace in accordance with a court case.

The City and WSDOT have been communicating for several years about the culverts in order to coordinate our efforts to replace the culverts in a way that results in a proper and efficient transition between the projects.

Preliminarily, there have been discussions about including L100 in a project for which LFP would be the lead agency to replace all three culverts and restoring the creek in the collapsed portion. This proposal would be very similar to that which occurred during the replacement of the Lyon Creek culverts in 2015, where the replacement of WSDOT’s culvert under SR 522 was included in the City’s culvert replacement project, with WSDOT reimbursing the City for the cost of design and construction. 

While that arrangement worked well, WSDOT has scheduled the replacement of L100 for 2021 while the City project is not expected to be ready for construction until 2022.  We are not ruling out a joint project, however, and will continue to communicate with WSDOT on this topic during design.
