Detention Basins
Detention basins are surface landscaped depressions that are designed to provide storm water attenuation storage during high intensity rainfall events. Landscaping of detention basins may consist of vegetation or hard landscaping elements; however, hard landscaping is more typically used in high density urban environments, where the system serves a specific secondary amenity purpose (i.e. seating and high use recreational space.)
