Which term is typically used as an example of an Urban BMP?

• A. Rain garden
• B. Cover crop
• C. Riparian buffer
• D. Detention basin

Answer: (A)

Urban BMPs are practices that manage stormwater right where it falls in built environments, using methods that infiltrate, filter, or slow runoff to protect water quality and reduce flooding. A rain garden fits this idea perfectly. It’s a shallow, planted depression designed to receive runoff from roofs or pavement, letting water infiltrate through the soil and be treated by plant roots, soil microbes, and sediment deposition. This green infrastructure is specifically tailored for urban settings because it can be integrated into sidewalks, parking lot islands, and yard spaces, requires relatively low maintenance, and provides tangible benefits like reduced runoff volume and pollutant loading. Cover crops are primarily an agricultural tool for protecting soil on farms, not a standard urban feature. A riparian buffer is valuable for protecting streams and can exist in urban areas, but it’s more a watershed-wide protection measure rather than a common on-site urban stormwater solution. A detention basin is an engineered structure that stores runoff to limit peak flows, which is common in urban planning, but it’s a traditional gray infrastructure approach; rain gardens represent the preferred green, on-site, urban-friendly example.
