It has been determined that there is continued Federal interest in a project along the shorelines of Treasure Island and Long Key, Pinellas County, Florida, based on the Tentatively Selected Plan (TSP) identified using the U.S. Army Corps of Engineers (USACE) Planning Process.
The TSP includes periodic beach nourishment, including dune and berm features, at the north and/or south ends of Treasure Island and Long Key.
Some key details of the TSP design continue to be refined, including the estimated periodic nourishment interval, the estimated volumes required for periodic nourishment, the landward location of the beach nourishment template, and the estimated project cost. Periodic nourishment of the improved beach, which would be provided when needed, would restore the beach to desired dimensions. Sediment transport along these islands links the geomorphic response of the shorelines; therefore, periodic nourishment for any other areas where erosion might develop would also be provided when needed.
The Tentatively Selected Plan does not have a specific design level. In other words, the project is not designed to fully withstand a certain category of hurricane or a certain frequency storm event. The proposed project would greatly reduce, but not completely eliminate, future coastal storm risk and damages over the 50 year period of analysis.
