Bay Shore — 26,337 residents in the Town of Islip — is the gateway community to Fire Island and Robert Moses State Park, sitting directly on Great South Bay with miles of waterfront residential development that faces the same recurring tidal flooding as Nassau’s south shore communities. The Fire Island Inlet to the east allows storm surge energy from the Atlantic to propagate into Great South Bay, amplifying surge levels in Bay Shore during events that approach from the southeast.
Category 3 Bay Water Protocol
Great South Bay water reaching Bay Shore south shore properties during storm surge events is Category 3 contaminated water under IICRC S500 — requiring demolition of all wet porous materials, structural decontamination, and clearance testing before reconstruction. Bay Shore homeowners who experienced Sandy flooding and had surface cleaning rather than full Category 3 remediation may have hidden mold in wall assemblies alongside the same legacy contamination issues seen in Nassau’s south shore communities.
Cost Benchmarks
- Great South Bay storm surge, Category 3: $18,000–$45,000.
- Interior Bay Shore pipe failure: $6,500–$16,000.
- Sewer backup (Category 2): $5,500–$13,000.
