Common bioretention opportunities include landscaping islands, cul-de-sacs, parking lot margins, commercial setbacks, open space, rooftop drainage and street-scapes (i.e., between the curb and sidewalk). Bioretention, when designed with an underdrain and liner, is also a good design option for treating Potential stormwater hotspots. Bioretention is extremely versatile because of its ability to be incorporated into landscaped areas. The versatility of the practice also allows for bioretention areas to be frequently employed as stormwater retrofits."> '''bioretention practice'''</span> |

Example goals and objectives when planning green infrastructure
Link to this table
| Example goals | Example objectives |
|---|---|
| Improve water quality, especially in areas with impaired or polluted waterways | Install GSI upland of waterways Preserve buffer zones around waterways |
| Alleviate recurring local flooding issues | Install infiltration-based GSI. Reduce imperviousness through GSI |
| “Green” highly impervious or urban areas to reduce the urban heat island effect | Increase tree canopy Reduce imperviousness through vegetation-based GSI practices like bioretention practice |
| Provide a neighborhood or community amenity | Incorporate GSI as part of a larger neighborhood amenity like a pocket park or playground |
| Increase biodiversity and native habitat | Use native vegetation as part of a GSI project |
| Address socio-environmental issues in the community | Incorporate GSI as part of an overarching strategy to address socio-environmental concerns |
