11. COMMERCIAL CONCEPTUAL DIAGRAM Commercial tracts offer similar opportunities to utilize bio-swales and underground rain tanks to filter and store storm water. Retention can be built into the detention systems for irrigation use. Rain tanks allow increased developable land. LID features again serve double duty as amenity areas within the retail areas.
