Annual Operation and Maintenance Verification Instructions

BMP Program Flyer

For general information about the program, click on the adjacent Structural BMP Information Guide.

The County will send you Operation and Maintenance Verification Forms each year, to help guide you through the BMP maintenance process. You are required to complete the following steps:

Step 1: Locate all of your BMPs

Your BMPs will be listed on the Operation and Maintenance Verification Forms sent to you by the County each year. Their specific locations are listed on your development’s grading plan. Storm drain inlet filters are found in nearby storm drains, while other BMPs may be located near the point where storm water runoff leaves your property or development. For BMP types, click here.

Step 2: Inspect and maintain your BMPs

Your Operation and Maintenance Verification Forms will include instructions on how to inspect and maintain your BMP. Typical maintenance includes removing trash and accumulated sediment, trimming overgrown vegetation, repairing eroded areas, and replacing damaged BMP components. Make sure to record your inspection findings and maintenance activities in your Verification Forms. For additional guidelines, review our BMP Fact Sheets.

Step 3: Take a photo of your BMP

After your BMP has been inspected and/or maintained, take a photo of the BMP.  The photo should show that the BMP is in good condition and ready for the upcoming rainy season. Make sure to take at least one photo of each BMP. For tips on how to take good photos of your BMPs, click here.
