* Grade impervious surfaces, such as driveways, during construction to drain to vegetated areas.
* Minimize the area of impervious surfaces such as paved areas, roof and concrete driveways.
* Incorporate pervious or porous surfaces (e.g., gravel, permeable pavers or blocks, pervious or porous concrete) that minimize runoff.
* Direct runoff from paved surfaces and roof areas into planting beds or landscaped areas to maximize site water capture and reuse.
* Incorporate rain gardens, cisterns, and other rain harvesting or catchment systems.
* Incorporate infiltration beds, swales, basins and drywells to capture storm water and dry weather runoff and increase percolation into the soil.
* Consider constructed wetlands and ponds that retain water, equalize excess flow, and filter pollutants.
