Structural BMP Verification

Structural BMP Online Portal

Stormwater structural BMPs require regular maintenance to effectively remove pollutants from stormwater runoff. To verify that your structural BMPs are properly maintained, you will need to do the following:

Step 1: Inspect your BMPs

The envelope you receive from the County will include general guidance on how to inspect and maintain your BMPs. If you need help locating your BMPs, you can visit the County's Structural BMP Verification Portal to view a map with the location of your structural BMPs.

Step 2: Maintain your BMPs

Typically, maintenance will include removing trash and accumulated sediment, repairing eroded areas, trimming overgrown vegetation, and replacing any damaged components. View our Structural BMP Fact Sheets for more information about maintaining specific BMP types.

Step 3: Take photos of your BMPs

After all necessary maintenance has been completed, take photos of each BMP. View our BMP Photo Guidance for tips to help you take effective BMP photos.

Step 4: Submit your BMP verification online

Visit our Structural BMP Verification Portal to complete your BMP verification online. Before you get started, read our online submittal instructions.


If you are unable to submit through the online portal, you may send your verification forms, BMP photos, and any other documentation (service invoices, receipts, etc.) to the County by email:

Include your address and the words "Self-Verification" in the subject line.

Note: Emails sent to this address must be smaller than 10MB. Larger emails cannot be received.
