The City of Charleston Basin Flood Action Committee met on November 5, 2026, to discuss flood response, stormwater management, and resilience. Staff described improvements to the city’s real-time road-closure system, including direct integration with Waze, Google Maps, Apple Maps, and TomTom, plus GIS tools using road-closure, tide, rainfall, and Waze-report data to analyze past and forecast street flooding. The committee also received an overview of the city’s stormwater design manual, updated in 2025. Requirements include designing for a 5.5-foot elevation benchmark to account for sea-level rise and storm surge, runoff controls for development, and wetland-function analysis. The city is encouraging low-impact development through storage credits and other incentives, and staff discussed watershed-specific requirements, basin improvements, and wetland protections.

The committee heard that the city is coordinating with the Army Corps of Engineers on resilience work and that a pump-station upfit at MUSC is under construction. No contract awards, solicitations, vendor selections, dollar amounts, procurement votes, or spending motions were identified. The meeting was informational, with discussion focused on standards, flood-data tools, and ongoing resilience and stormwater projects.
