How big is a shallow flooding base floodplain?

Shallow flooding base floodplain. BFEs are provided. Coastal areas subject to wave action greater than 3ft. Coastal area subject to a velocity hazard (wave action greater than 3 ft.) where BFEs are not determined on the FIRM.

What is the Charleston peninsula flood risk management study?

The Charleston Peninsula Coastal Flood Risk Management Study is a federal feasibility study that investigates coastal storm impacts on the Charleston peninsula. In partnership with the City of Charleston and its stakeholders, the study also explores economically-viable and environmentally-sound solutions to mitigate coastal storm risks.

How are storm surges affecting the Charleston peninsula?

Working in tandem with other flood mitigation efforts, the study primarily addresses the risks of coastal storm surges and considers tidal flooding and sea level rise in its analysis. Coastal storms on the Charleston Peninsula place people at risk, including the potential for loss of life and declines in public health.

When did the Charleston peninsula feasibility study start?

In partnership with the City of Charleston and its stakeholders, the study also explores economically-viable and environmentally-sound solutions to mitigate coastal storm risks. The feasibility study began in 2018 and is 100 percent federally funded through Emergency Supplemental Funding.
