The finished result
What project qualifies?
This program may support more than one approved project route. The program’s plan and written decision control which route applies to the property.
An approved planted feature slows, stores, filters, or infiltrates runoff on the property. Impervious pavement is removed or replaced with an approved surface and base that lets water pass through. A roof or large property stores, slows, treats, or reuses stormwater through an engineered green-infrastructure system.
