Which is an Urban BMP example?

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

Answer: (A)

Rain gardens embody urban stormwater management by using on-site, green infrastructure to handle runoff. They are shallow planted depressions placed in urban landscapes near impervious surfaces like roofs and driveways. When rain falls, water is directed into the garden, where it infiltrates the soil, is taken up by plants, and passes through a natural filtration process that removes sediments and nutrients before reaching the storm drains. This approach reduces peak flows, helps prevent sewer overflows in city systems, and improves water quality right where people live. Detention basins, while used in cities, are larger engineered structures that temporarily store runoff and release it slowly; they represent a more traditional gray infrastructure approach rather than a green, landscape-based solution. Cover crops are agricultural practices to protect soil on fields, not urban environments. Riparian buffers are vegetated zones along streams and are common in watershed or rural restoration contexts, not specifically urban stormwater management.
