A storm water pollution project at Chattahoochee High is getting overflowing support from a county commissioner.

A $75,000 grant check was presented to the Chattahoochee Cougar Foundation Inc., a nonprofit organization affiliated with the high school, Wednesday by Fulton County Commissioner Lynne Riley.

The grant will be used for the construction of the ARCH project, an effort to remedy a growing community problem of storm water pollution, to be housed at Chattahoochee High.

The proposed project incorporates a constructed wetland detention pond for storm water runoff, amphitheater and environmental education stations, officials say. The wetland detention pond will retain and clean storm water through a bioremediation filtration process before it enters Johns Creek. Drainpipes entering the ARCH will be fitted with engineering devices for the removal of macro-pollutants and sediments.

Chattahoochee's grant is one of three presented to environmental nonprofits in North Fulton County. Earlier this month, Riley presented the Mountain Park Watershed Preservation Society Inc. a $91,700 grant to purchase approximately 20 lots on the shore of Lake Garrett for environmental green space in the city of Mountain Park. She also presented Keep Roswell Beautiful Inc. with a $68,000 grant to fund tree replacement and education markers in Roswell Area Park and intersection beautification.
