What Are BMPs?

A Best Management Practice (BMP) is a structural or non-structural control measure designed to prevent, treat and manage urban stormwater runoff and mitigate pollution impacts. They can be physical or mechanical controls designed to manage the pollutant and improve the quality of water.

The type of BMP will vary depending on the site’s specific need or constituent of concern. A structural BMP is a mechanical or physical device installed as a stormwater treatment control to remove pollutants. Examples are: bioretention, catch basin filters, media filters, or other treatment technologies. Non-structural BMPs focus on the prevention of stormwater pollution, and include: watershed planning, signs that encourage “No Dumping – Drains To Ocean,” and educational handouts.

Federal, state, and local agencies require monitoring, maintenance and record keeping of installed BMPs for continued effectiveness and meeting water quality objectives.

The most cost-effective way to manage stormwater runoff begins with avoidance of issues. Preventing pollution is often far cheaper than correcting the problem. Costs associated with a spill cleanup can be significant. Allocating a small fund toward preventative maintenance could save thousands of dollars in the long run.
