RAIN MANAGEMENT A set of narrow slits controls water access into the system
RAIN MANAGEMENT One type of in-system overflow splitter simply backs up water
RAIN MANAGEMENT Overflow splitters can be curb cuts located downhill

Photo courtesy of Carol Meyer Reed ARTFUL RAINWATER DESIGN Responds to regulatory demands Manages runoff in responsible ways Uses rainwater as a resource Transforms people s perception of rainwater
Utility Goals: - Reduce pollutant loads - Reduce downstream damage - Safely move, control, contain - Capture rain for reuse - Restore or create habitat Amenity Goals: - Education - Recreation - Safety - Public Relations - Aesthetic Richness
Sustainable Stormwater Management Techniques: - Rainwater Trail - Flow Splitter - Rainwater harvesting container - Flow-through filter planter - Dry detention basin - Wet detention basin & constructed wetland - Infiltration basin or trench - Rain garden - Bioswale
