Treasure Island is a barrier island with Gulf frontage on one side and Boca Ciega Bay canals on the other. Helene left documented sand deposition heavy enough to bury cars and close the island — a useful marker of how much material moves across a shoreline in a single event.
City of Treasure Island and Pinellas County, with state and federal review by scope
Pinellas County. Depending on scope and waterway, state and federal review may also apply.
Everything below carries a classification label and a source. Where a source conflicts with another, both are shown.
Read carefully: Coverage conflicts on scope: one outlet describes five waterways while the itemised reporting names four. Both are recorded here and neither is adjusted. This programme is public creek and streambank work — it is not a private seawall funding source, and no part of it should be read as available to a private owner.
