Benton County Stormwater Management Plan
This plan was developed by Benton County staff from Community Development, Environmental Health, and Public Works in 2007. The plan was adopted by the Benton County Board of Commissioners and is being reviewed by the Oregon Department of Environmental Quality. An update to the plan was completed in 2011 as required by State and Federal law (see ODEQ permit renewal application package requirements linked below).

Stormwater Program 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 ‘urban areas' around the cities of Corvallis and Philomath known as the Federal Urbanized Area (map also available at link below).
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.
