Preston Maintenance Facility

Project No.:  1127271

Project type:  Miscellaneous

Project description

Re-locate the Division 2 Maintenance Regional Shop from its current location in Fall City and move it to the Preston Maintenance Facility owned by the Washington State Department of Transportation.

Why is King County doing this project?

The Facilities Master Plan for the Road Services Division points out that the Fall City facility, that serves the Maintenance Division 2 service area, does not meet the Road Services Division’s location and functional standards. In order to bring the buildings and facilities up to standard, they would need to be reconstructed. However, the current location on Preston-Fall City Road is not appropriate as service from this location is impacted by flooding. Additionally, the site is undersized to place all the critical functional and operational facilities of a regional maintenance shop.
 

Project management phase:  Preliminary Design
