Step 1. Land Use
This matrix allows the designer to make an initial screen of practices most appropriate for a given land use.
Rural. This column identifies STPs that are best suited to treat runoff in rural or very low density areas.
Residential. This column identifies the best treatment options in medium to high density residential developments.
Roads and Highways. This column identifies the best practices to treat runoff from major roadways and highway systems.
Commercial Development. This column identifies practices that are suitable for new commercial development
Hotspot Land Uses. This last column examines the capability of an STP to treat runoff from designated hotspots. An STP that receives hotspot runoff may have design restrictions, as noted.
Ultra-Urban Sites. This column identifies STPs that work well in the ultra-urban environment, where space is limited and original soils have been disturbed. These STPs are frequently used at redevelopment sites.
Note that, while most of the land use decisions serve primarily as guidance, hotspot restrictions should typically be regulatory.
