Travelers can expect some delays on Northwest 99th Street during construction, but all travel lanes will remain open

VANCOUVER – Clark County is installing a large stormwater filter vault to treat runoff from approximately five acres of impervious surfaces along Northwest 99th Street, Northwest 9th Avenue, and the surrounding area. Three stormwater filter catch basins will also be installed. Construction will begin in July.

Travelers can expect some delays on Northwest 99th Street during construction, but all travel lanes will remain open. Drivers are reminded to slow down, pay attention and be patient in work zones.

Updates will be posted on the project webpage at clark.wa.gov/public-works/northwest-99th-street-water-quality-retrofit-northwest-11th-avenue-cougar-creek.
