Stormwater Management Program

The Charleston County Stormwater Management Program is a federally mandated program that is monitored by the South Carolina Department of Health and Environmental Control. It was created in 2006 in compliance with federal and state requirements related to water quality. Its staff includes engineers, technicians, plan reviewers, inspectors, survey personal, and accountants all working towards a singular goal: to ensure that our citizens can utilize Charleston County’s waters and beaches.

The urbanization of Charleston has led to an increase in polluted stormwater runoff making its way into our waterways, contaminating them. The Stormwater Management Program aims to reduce the amount of runoff pollution. It does this by educating the public about how they can reduce the risk of polluting rainwater, permitting and monitoring all new construction sites to prevent the many potential contaminants from entering the storm drain system, and monitoring businesses and residential homes to make sure no pollutants are being discharged into waterbodies.

Grimball Road Drainage Improvements Project

The Grimball Road Drainage Improvements project includes the construction of a reinforced concrete pipe under Grimball and South Grimball Roadways. This will help to alleviate some of the known flooding issues in this area of James Island. Work will take place on Grimball Road across from the James Island Elementary School. Construction is scheduled to begin in the 4th quarter of 2020 and will close the road for approximately two months. Charleston County will put out a news release to alert citizens of the exact dates of the road closure and detour routes. Please watch the below video for more details about this project.
