Construction is scheduled to occur at night in September and October; work will require lane closures

VANCOUVER – Beginning in September, Clark County is expanding infrastructure to filter stormwater runoff from Northeast 99th Street between Interstate 5 and Northeast Hazel Dell Avenue. The upgrades will capture pollution and provide increased water quality treatment before runoff from the road discharges into Suds Creek.

Construction is scheduled to occur at night in September and October. Work will require lane closures. Travelers in the area can expect some delays. Drivers are reminded to slow down, pay attention and be patient in work zones.

Construction schedules are subject to change and are weather-dependent. Project updates will be posted at clark.wa.gov/public-works/northeast-99th-street-catch-basin-water-quality-retrofit.

For information about road and park projects, closures, opportunities for community input, and more, residents can follow Public Works on X (formerly known as Twitter), Facebook and Instagram and view information on Nextdoor.
