Treatment Control Best Management Practices (TC BMP) Inspection and Maintenance Verification Program

Treatment control BMPs are permanent storm water treatment features incorporated into the design of many newly developed or redeveloped properties. To continue functioning properly, these BMPs need to be maintained regularly.

Owners and operators of these properties are required to conduct regular maintenance activities, as per maintenance agreements signed with the City of San Diego (City) and filed with the County Recorder's Office.

In addition, the City is required to verify proper maintenance of these treatment control BMPs via inspection. These activities are mandated by the City’s Municipal Code (§43.03).

The City's TC BMP program has two main components:

1. An annual maintenance verification form

  • Parties responsible for BMP maintenance will receive a form in the mail each year. They are required to complete and return the form, verifying that they are performing all necessary routine maintenance of treatment control BMPs on their property.
2. Periodic treatment control BMP maintenance inspections

  • City representatives periodically visit sites to assess whether the treatment control BMPs are being properly maintained. Examples of items that an inspector commonly checks can be found in the "BMP Inspection Item List" document available below.
