Elevation & Freeboard
Foundation Type
Replacement Cost

Distance to Water

FEMA evaluates proximity to oceans, rivers, marsh, and surge-prone areas. In Myrtle Beach, homes closer to the coast or Intracoastal Waterway often carry higher flood risk.

Elevation & Freeboard

Raising the first living floor significantly reduces flood exposure. Many Myrtle Beach builders now include 1–3 feet of freeboard to improve insurance outcomes.

Foundation Type

Pile-supported homes let water pass beneath them, reducing structural impact. Slab-on-grade homes in low-lying spots may see higher premiums under Risk Rating 2.0.

Replacement Cost

FEMA uses replacement cost value—not market value—when calculating insurance premiums. High-end coastal builds reflect this elevated reconstruction cost.
