| dc.description.abstract | Infrastructure along the Gasparilla Island, Lee County, Florida shoreline, is subject to damage from wave attack, erosion, and inundation caused by coastal storms. It is projected that storms in the study area will continue damaging infrastructure and limiting habitat. This study analyzes the authorized project, and its optimization that addresses these vulnerabilities, as well as incidental opportunities for maintenance of environmental resources and recreation for the Gasparilla Island segment along the Gulf of Mexico shoreline of Lee County, Florida for the 40-year period of analysis from 2016 to 2056. The purpose of the present Section 934 study is to determine if future nourishments of the Gasparilla segment of the Lee County, Florida Shore Protection Project warrant an extension of Federal participation to the year 2056. Federal participation expired in December 2016, ten calendar years after initial construction in 2006. The non-federal sponsor is Lee County, Florida, represented by the Board of County Commissioners. | en_US |
