Rogue Valley Stormwater Design Manual


Rogue Valley Stormwater Design Manual

The Rogue Valley Stormwater Design Manual (RVSWDM) applies to the cities of Ashland, Central Point, Medford, Phoenix, Talent and urbanized unincorporated Jackson County. Projects that will develop or redevelop more than 2,500 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.

RVSS Stormwater Quality Incentive Policy

Stormwater Plan Submittal Requirements

Rebuilding After the Almeda Fire:
Within the Almeda fire destroyed area, stormwater management will be required for any project redeveloping impervious areas in excess of the original impervious surface square footage. Impervious surface is defined in RVSS' code as "a surface that prohibits or limits water from soaking into the ground. Types of impervious surfaces include rooftops, traditional asphalt and concrete parking lots, driveways, roads, gravel lots and roads; and heavily compacted earthen materials, sidewalks, and pedestrian plazas. Gravel surfaces used for vehicular traffic are considered impervious." A site plan showing the original footprint and proposed new impervious surface footprint must be submitted to RVSS for review.

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, see the Erosion Control page.
