Figure 3. Map of GI incentive programs from MS4 Phase 1 cities across the US.
Note: not all states had publicly available Stormwater Management Plans (SWMPs) online and therefore any programs in these states were not captured by this scan; additionally, MS4 Phase 1 cities have a population of 100,000 or more meaning that areas with smaller population are also not captured by this scan.
