11Oliver Point and Oliver Reef 28°38'30.51"N 96°14'27.59"WOliver Pt. eroded and opens Coon Island Bay to high energy waves; Oliver Point Reef was flattened during hurricane Claudette. Use Oliver Point as a potential BU site for maintenace dredging of Palacios channel and restoer Oliver Point Reef. Reef construction could improve storm resilience along Palacios waterfrontXX
12Wells Point to Carancahua 28°38'2.60"N 96°20'24.06"WShoreline erosion at select locations. Protect shorelinesXX
13Red Fish/Salt Lake mouth of Carancahua 28°37'17.62"N 96°22'47.22"WHurricane Claudette widened and deepened an existing washover into Redfish Lake. Tidal flow and wind-driven currents continue to erode , destroying emergent oyster reef (black skimmer habitat) and altering other Redfish Bay habitats. Continued erosion and uncontrolled tidal action could result in b reaching of Salt lake and furhter habitat losses. Restore protective barrier, oyster reef, marsh and sea grasses. XX

15Matagorda Bay Bird Islands 28°30'42.29"N 96°25'28.30"WChester Island is currently the only rookery island in West Matagorda Bay. Sundown Island is located in a high current area and subject to excessive land-loss from erosion. Employ BU strategies to build other rookery islands that are not subjected to highly erosive tidal currents
