A long-awaited draft feasibility study released by the Texas General Land Office and the Army Corps of Engineers pegs the cost of constructing a series of resiliency projects along the Texas coastline at between $23 and $31 billion.
The largest project in the study is a storm surge barrier between Bolivar Peninsula and Galveston Island, known as the "Ike dike" or the "coastal spine." Other solutions include levees, floodwalls, surge barrier gates and breakwaters and natural barriers such as shoreline erosion control through marsh, beach, dune and island restoration.
