Bioretention basins are small landscape practices that may infiltrate stormwater into the subsoil, and/or hold it for a period of time to settle out pollutants and allow some uptake by plants. They are normally constructed as a simple depression in an existing landscape. They may be designed with meadow-type plantings or more formal beds, depending on their location. Bioretention basins can be sited in a wide range of different locations and settings and are commonly used as a high-performance alternative to traditional landscaped gardens or planting beds. By co-locating stormwater management with visually appealing landscaped areas, designers may be able to maximize the remaining area available for building.
