Which BMP would be classified as non-structural?

Non-structural best management practices (BMPs) focus on the behavioral and procedural aspects of stormwater management rather than on physical structures that control stormwater. Public education and outreach is a prime example of a non-structural BMP because it aims to inform and engage the community in practices that can reduce stormwater pollution and promote better stewardship of water resources. This includes initiatives like workshops, community clean-up events, and information campaigns that encourage individuals and groups to adopt pollution prevention strategies.

In contrast, other options involve physical structures or technologies designed specifically to manage stormwater. A retention basin, porous pavement system, and detention pond are all structural BMPs that physically alter the landscape to manage water flow and quality. They are designed to capture, detain, or infiltrate stormwater runoff, demonstrating the defining characteristics of structural BMPs.
