Central Park Drainage Basin Improvements

Introduction

The Central Park Drainage Basin is located on James Island and is generally bounded to the south by Central Park Road, the north by Maybank Highway, the east by Folly Road, and the west by Woodland Shores.  

The area experiences significant flooding from increased development and restricted conveyance and outfall systems. 

 The area is a mixture of City of Charleston and unincorporated Charleston County jurisdictions with both local and State Department of Transportation roadways.  

The City of Charleston, in conjunction with Charleston County, has performed a drainage improvement evaluation for the basin and has recommendations to alleviate frequent flooding, and improve overall drainage.

The project to date began in 2019 and consists of the following elements:

1. Review of existing stormwater mapping data
2. Stakeholder meetings and public outreach
3. Stormwater infrastructure review
4. Stormwater computer modeling and analysis of data
5. Conceptual project recommendations and prioritization
6. Presentation to the James Island Intergovernmental Drainage Committee
7. Survey Work to define the critical line delineation for the Central Park Watershed
