Stormwater Quality Design Manual

The Rogue Valley Stormwater Quality Design Manual (RVSWDM) applies to the cities of Ashland, Central Point, Medford, Phoenix, Talent, Eagle Point, and urbanized unincorporated Jackson County. Projects that will develop or redevelop more than 5,000 square feet of impervious surfaces (buildings, roads, parking lots, etc.) on a site must manage stormwater runoff in compliance with the Rogue Valley Stormwater Quality Design Manual (RVSWDM) found below.

Rebuilding After Fire:

Within the Almeda fire destroyed area, RVSS will follow the lead of the county and cities with regard to stormwater management requirements. For projects that the county/city require site plan review, RVSS will require submittal of a stormwater management plan in compliance with the current (at time of submittal) Rogue Valley Stormwater Quality Design Manual.  If no site plan review is required by the city/county, RVSS will not require stormwater management.

An Erosion prevention and sediment control permit (1200-C/CN) will still be required for all projects disturbing over one acre. Application materials should be submitted directly to RVSS.

Stormwater Facility Design and "No Net Loss" for NFIP ESA:

The SWAT has analyzed the Model Floodplain Management Ordinance published in November 2024 for the NFIP Endangered Species Act Integration in Oregon.  The SWAT has concluded that the Rogue Valley Stormwater Quality Design Manual (RVSQDM) can be used for stormwater facility design when development includes an increase in impervious area and satisfies the intent of the Model Ordinance for “No Net Loss”.
