Castle Rock Stormwater Improvements

Cowlitz County, Washington is requesting bids for stormwater and parking lot improvements at a fire dispatch building under a project due September 24, 2026. Work must be completed during normal building operation with no building closures permitted—a constraint that will govern scheduling and sequencing.

The scope includes drainage infrastructure replacement and new installation: removal and replacement of approximately 280 linear feet of 4-inch roof drain pipe, installation of an 85-linear-foot interceptor trench, a 70-linear-foot shallow drain within the building's 2.5-foot crawl space, three new catch basins with associated piping, and grading within the crawl space. Site work includes a new exterior crawl space entrance, approximately 90 square yards of concrete surfacing surrounding the building perimeter, and site restoration encompassing concrete, asphalt, grass areas, and a small rockery. An additive schedule includes chip seal and fog seal treatment for approximately 1,860 square yards of parking lot (with site preparation, wheel stop removal and reinstallation, and paint markings in kind) and construction of a new hot mix asphalt driveway connecting the parking lot to an accessible parking pad near the dispatch building.

The project specification document (DNR 26-E13.pdf) establishes technical requirements and contractor performance standards. Estimated contract value, contract term, evaluation criteria, pre-bid meeting date, and question deadline are not specified in the posted materials. The incumbent contractor is not identified.
