Planting trees could be part of the drainage solution

The City of Charleston is partnering with the South Carolina Forestry Commission and the U.S. Forest Service on an 18-month study examining how tree-planting can reduce erosion and stormwater runoff.  The study is expected to be completed in the early spring of 2018.  View the project outline here: http://www.charleston-sc.gov/DocumentCenter/View/14905

Research shows that one acre of impermeable pavement generates 36 times more stormwater runoff than a forested acre.  The study will examine whether the city has the capacity to expand and maintain its urban forestry program.  It will also look at retrofitting paved areas which are no longer in use, such as an abandoned parking area near Union Pier downtown.  The abandoned Church Creek Plaza would be another location where a paved area could be retrofitted.

Among the approaches looked at during the West Ashley Master Plan technical review were to allow stormwater runoff fee or property tax credits to property owners which upgrade parking lots with vegetation and permeable pavement and retrofitting parks with more absorbent plants.  The recently completed Church Creek Drainage Basin Study did not consider those approaches in its findings.
