Mount Pleasant's own low-lying flood and resilience studies

The Town of Mount Pleasant Engineering & Environmental Division publishes two named studies of chronic and future flooding, both listed live on 2026-09-04. (1) 'Low Lying Flood & Resilience Study - Remley's Point, Royall Avenue, and Ravens Run.' The Town's stated background: 'Communities like the City of Charleston, City of Isle of Palms, City of Folly Beach, and Town of Sullivan's Island have all recently developed or updated plans/analyses quantifying the risk of sea level rise and coastal flooding for their respective communities. These communities are much lower in elevation than the Town of Mount Pleasant and are therefore more susceptible to the risks of sea level rise and coastal flooding. However, large areas of Mount Pleasant are still at risk.' Stated objectives: complete a sea level rise and storm surge analysis; develop comprehensive models of the study areas; identify locations within study areas susceptible to flooding; study physical and financial impacts. The study document is posted on the page. (2) 'Sea Level Rise Pilot Study - Haddrell Street and Darrell Creek Subdivision.' The Town also runs a Stormwater Improvement Program in the Old Village and publishes individual drainage capital projects (for example Hobcaw Drainage Improvements and a Saltgrass Pointe drainage improvement public notice). These are the closest thing the Town publishes to a chronic street-flooding map; there is no single Town-published street-flooding map layer. Charleston County's GIS hub also carries a Flooding page.
