Mount Pleasant sits across the harbor from Charleston, between the Cooper River and the Atlantic beaches, in some of the lowest-lying developed land on the East Coast. Hurricanes define the risk calendar from June through November: surge pushes through the harbor and up the rivers, the barrier islands take the first hit, and mainland neighborhoods flood when water stacks higher than roads and drainage can handle. The region's 1989 benchmark storm reshaped Lowcountry building codes, but water remains the adversary no code fully defeats.

Daily life here already includes a preview of the hazard. Tidal flooding — "sunny day" flooding on high tides — regularly ponds water in the lowest streets around Shem Creek and the marsh edges, and each year of higher tides pushes that line slightly farther inland. When a tropical system adds surge and rainfall atop an already-high tide, flooding compounds fast. Newer construction generally sits higher and meets stricter wind standards, but older homes near the water carry the most exposure.

Homeowners should treat elevation as the single most important number about their property: know it, and compare it honestly against recent flood events. Flood insurance is close to essential this close to the coast, hurricane protection for windows and roofs should be in place before summer, and an evacuation plan matters because the bridges to the islands close early. Keep drainage clear and watch the tide charts — in Mount Pleasant, the ocean visits the streets even without a storm.
