Stormwater Program

Stormwater Area Map

Background
Starting in 2007, Benton County staff from Community Development, Environmental Health, and Public Works developed and successfully implemented a National Pollutant Discharge Elimination System (NPDES) program (see program brochure).

The program requirements are part of the Clean Water Act that local governments and private organizations must comply with for discharges of pollutants into the waters of the United States and regulating quality standards for surface waters. This means that there are many actions that the county is taking in the ‘urbanizing areas' around the cities of Corvallis and Philomath known as the Federal Urbanized Area (see Corvallis area map above at right).

The overall goal of the Benton County Stormwater Program is to reduce the volume of runoff from current development (for example parking lots, subdivisions) and the developing landscape, while reducing the amount of pollutants carried by stormwater runoff to our rivers and streams. In order to meet this overall goal Benton County staff has developed and implemented Six Minimum Control Measures.

Please report spills within the county roadways to: Benton County Public Works: 541-766-6821. Please report spills within the private land outside of the roadways to: Benton County Environmental Health at 541-766-6841

IF YOU HAVE AN EMERGENCY OR HAZARDOUS SPILL CALL 9-1-1:. Be ready to provide the location, severity, actions taken, and responsible party. Remember that early response protects our shared water quality!
