The City of Charleston is one of thirteen southern localities that has received funding to carry out a project to link urban tree canopy to stormwater mitigation, specifically for cities with Municipal Separate Storm Sewer Systems (MS4) permits to manage stormwater. The project is helping southern cities utilize their urban forests to better manage and reduce stormwater runoff. Urban trees soak up tremendous volumes of stormwater.
The more treed the landscape, the less runoff and flooding may occur. This project will assess the city’s tree canopy and determine its role for treating and absorbing stormwater.
Project partners include the City of Charleston, The South Carolina Forestry Commission and The Green Infrastructure Center (GIC). Funding is provided by the United States Department of Agriculture Forest Service and matched in-kind through participation by the City.
City agencies involved on the Project’s Technical Review Committee include Information Technology and Geographic Information Services; Parks and Urban Forestry; Planning, Preservation and Sustainability; and Public Service and Stormwater Management. Staff from these departments formed a technical review committee, advising the GIC and coordinating Charleston community events.
Why has the Project Been Funded? Rapid urbanization and climatic fluctuations have led to increased risk of flooding and degraded water quality in cities. Trees can be utilized as a key strategy for addressing this problem. Trees intercept, store and transpire storm water and are a vital tool in abating and cleaning storm water runoff. One urban tree can intercept thousands of gallons of water annually.
But while the benefits of trees are well known, most cities do not include trees as a component of their storm water management strategies.
The project began in November 2016. The case study report was completed in August 2018, and the grant period ended September 2018.
What Will Charleston Receive for Participating? The primary outcome is a process for integrating trees into the City’s storm water management program. Ultimately, Charleston will have a more strategic and effective process for combating storm water runoff.
Charleston will receive:
In addition to the outcomes listed above, by better evaluating and planning for its trees, Charleston will also realize other ‘ecosystem services’ of the urban forest such as:
