Evacuation & flood

Read this first

This page does not tell you what to do. It tells you who decides, and where they publish it — the South Carolina Emergency Management Division, Charleston County Emergency Management, the Town of Mount Pleasant, FEMA and NOAA. Every figure below is attributed, and every link goes to the agency itself. In an emergency, follow the authority, not a real estate website. If you are in immediate danger, call 911.

Two things almost everyone has wrong

Mount Pleasant is predominantly Zone B. Charleston County has only three evacuation zones — A, B and C. Zone A is the barrier islands and the land east of US-17 running north; the town itself is listed under Zone B in the state's own plan. A town-wide answer does not settle an address, because boundaries follow roads and landmarks — look yours up on the state's Know Your Zone tool.

South Carolina does not issue “voluntary” evacuations. Those words are not evacuation categories in the state's published materials at all. There is one instrument — an Executive Evacuation Order from the Governor under S.C. Code § 25-1-440 — and it names the zones it applies to. Waiting for a “mandatory” upgrade that the system does not have is how people leave too late.

Two questions decide more about a Mount Pleasant house than almost anything else on this site: which evacuation zone it sits in, and which FEMA flood zone it sits in. The first matters a few days a year and matters enormously. The second is on every mortgage, every insurance quote and every renovation over a certain size. All 47 entries below carry the agency that publishes them.

Evacuation

What the South Carolina Emergency Management Division and Charleston County publish about zones, orders and routes. Look your own address up on the official tool — nothing here substitutes for it.

Flood zones & insurance

The zone letter on a parcel decides whether a lender requires flood insurance and what it costs. These are FEMA, county and town sources, not interpretations.

Zones, maps, rules and programs change, sometimes between hurricane seasons. Every link above goes to the responsible agency, which is the authority — this page is a directory to them and nothing more. Not affiliated with or endorsed by any agency named here. Nothing on this page is insurance, legal or safety advice.
