5 What are Green Streets? Portland Green Streets A sustainable stormwater strategy. Meets regulatory compliance and resource protection goals. Uses a natural systems approach to manage stormwater, reduce flows, improve water quality and enhance watershed health.

6 Goals for Mobile Green Streets Increase the water quality of Mobile Bay by filtering the stormwater entering the Bay from the downtown area Mitigate thermal pollution to Mobile Bay Reduce downtown impervious surface runoff to slow down stormwater runoff and maximize infiltration Lessen localized flooding on Dauphin Street and other midtown Mobile streets Reduce demand on the city s stormwater sewer collection system and provide additional storage capacity where needed

7 Goals for Mobile Green Streets Increase urban green space, connectivity to schools and wildlife corridors Improve air quality and reduce air temperatures Increase opportunities for economic development in the downtown area The Mobile Downtown Alliance and the Greater Mobile Chamber of Commerce recognize that a Green Streets approach is an important downtown redevelopment strategy!
