Stormwater Development Guidelines
Post-Construction Stormwater Runoff
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 found below.

Erosion Prevention and Sediment Control
All developments require some type of Erosion and Sediment Control permit. Read below to determine which permit applies to your project and how to obtain it.
RVSS Construction and 1200C Permits for RVSS Phase II Area
- RVSS Construction Permit is required when disturbing 1 to 5 acres. Sample permit
- 1200C Permit is required when disturbing 5 acres of more. Sample permit
- For both permits submit the following to RVSS:
- A complete, signed APPLICATION FOR NEW NPDES GENERAL PERMIT 1200-C
- Land Use Compatibility Statement (LUCS)
- Erosion and Sediment Control Plan
- Permit Application fee and 1st year annual fee is $1,500 (effective 3/21/2014) payable by check or credit card (MC, Visa, Discover) to RVSS.
- The annual permit renewal fee is $750 paid to RVSS.
- 1200-C permits for projects disturbing >5 acres renew through DEQ at their current rates.
- Application materials and guidance can be found on DEQ’s website.
- Small Lot permits are required when disturbing less than one acre. Small lot permits are obtained from the city in which the work will occur.
- A standard Erosion and Sediment Control Plan site detail for small lots is available.
- RVSS Stormwater Amendments to Code (.pdf) Full RVSS Code--see the RVSS Code page
Certified Erosion and Sediment Control Inspectors
- In order to obtain an RVSS or 1200C permit, you must have a certified Erosion and Sediment Control Inspector listed on your application. Certification is acquired through attendance and passage of an erosion and sediment control inspector class.
A list of current Certified Erosion and Sediment Control Inspectors can be found here.
RVSS offers Erosion Prevention and Sediment Control Inspector Certification classes two times each year, in late fall and in May. Dates are generally set one month ahead of time. Send an email to jmorgan @ rvss.us to be put on a notification list.
Alternate Erosion and Sediment Control Inspector Certification classes are offered through:
Northwest Environmental Training Center
Erosion and Sediment Control Best Management Practices
- RVSS worked with the Oregon Association of Clean Water Agencies to create a field guide of best management practices for use by contractors. Printed copies can be requested from RVSS.
- RVSS has put together a vendor list for erosion and sediment control products as a convenience to contractors.
- A pre-construction meeting with an RVSS inspector must be held on site to verify proper installation of best management practices prior to starting construction. Contact RVSS to schedule a pre-construction meeting.
- The designated Erosion and Sediment Control Inspector should complete inspection forms in compliance with the schedule dictated in their permit.
- Acceptable Inspection forms:
- Action Plans must be submitted to RVSS whenever a change is made to the approved EPSC plan. You may use the standard form from RVSS, create your own, or submit revised plans.
Name Change and Notice of Termination
- Erosion and sediment control permits are legal documents, thus if the entity responsible for the project changes, a Name Change form must be submitted to RVSS.
- When the project is complete, contact RVSS to schedule a final site inspection and then submit the Notice of Termination to RVSS.
- Name Change and Notice of Termination Forms are available on DEQ’s website.
