Stormwater infiltration BMPs - contributing drainage area
Link to this table
| Stormwater BMP | Recommended contributing area | Notes | References |
|---|---|---|---|
| Infiltration Basin | 50 acres or less | A natural or constructed impoundment that captures, temporarily stores and infiltrates the design volume of water into the surrounding naturally permeable soil over several days. In the case of a constructed basin, the impoundment is created by excavation or embankment. | [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13] |
| Bioinfiltration Basin | 5 acres or less | Bioinfiltration basins must meet the required 48 hour drawdown time and must be sized in order to allow for adequate maintenance. It is HIGHLY RECOMMENDED that bioinfiltration basins be designed to prevent high levels of bounce as submerging vegetation may inhibit plant growth. A maximum wet storage depth of 1.5 feet is HIGHLY RECOMMENDED. | |
| Infiltration Trench | 5 acres or less | ||
| Dry Well Synonym: Infiltration Tube, French Drain, Soak‐Away Pits, Soak Holes | 1 acre or less (rooftop only) | ||
| Underground Infiltration | 10 acres or less | ||
| Dry Swale with Check Dams | 5 acres or less | ||
| Permeable Pavement | It is RECOMMENDED that external contributing drainage area not exceed the surface area of the permeable pavement. It is HIGHLY RECOMMENDED that external contributing drainage area not exceed twice the surface area of the permeable pavement | It is RECOMMENDED that external drainage area be as close to 100% impervious as possible. Field experience has shown that drainage area (pervious or impervious) can contribute particulates to the permeable pavement and lead to clogging. Therefore, sediment source control and/or pre-treatment should be used to control sediment run-on to the permeable pavement section. | |
| Tree Trench/Tree Box | up to 0.25 acres per tree |
