Davis Islands study: backflow preventers and road elevation flagged as near‑term and long‑term tools
Summary
A state‑funded resiliency study of Davis Islands identified king‑tide and sea‑level rise exposure and recommended a mix of immediate steps (backflow preventers) and longer‑term measures (road elevation, seawall and ordinance updates).
Consultants and city staff presented a Davis Islands coastal stormwater and sea‑level resilience assessment that identified both near‑term measures to limit tidal inundation and longer‑term adaptation needs including roadway raising and seawall measures.
The study — supported through Florida’s resilient‑Florida funding established by 2021 legislation — surveyed roughly 80 outfalls on Davis Islands, quantified elevations and modeled sea‑level and tidal scenarios. Consultants said NOAA projections updated in 2022 raise the expected mean sea level at Tampa Bay to roughly 0.86 feet by 2040 and…
