Stormwater is rain or melting snow that does not infiltrate into the ground, but rather travels across landscapes such as construction sites, parking lots, roofs and roadways accumulating pollutants such as trash, oil, fertilizer, and sediment.

The storm drain system (MS4) serving the public streets, sidewalks and alleyways in the City of Meridian is owned and operated by the Ada County Highway District. ACHD administers a stormwater management program through enforcing construction site erosion and sediment controls, stormwater monitoring, public education, illicit discharge detection and pollution prevention.

Report stormwater pollution to the Stormwater Pollution Hotline – 208-395-8888

Report a clogged or blocked storm drain to ACHD 208-387-6350

Meridian requires that all City-owned Capital projects, regardless of size, meet minimum erosion and sediment control provisions including installation of Best Management Practices (BMPs), monitoring dewatering operations, and construction site management in order to ensure that pollution prevention is occurring on all City-operated job sites.
