The study looks at the economic costs, but makes no recommendation on how to move forward.

A report by a six-county group seeking better hurricane protection for the Texas coast says extending mainland levees and building a levee ring around the east end of Galveston Island would be cheaper and have more economic impact than a proposed a 55-mile seawall, also known as the “Ike Dike.”

The Gulf Coast Community Protection and Recovery District cost-effectiveness study estimates that the extension and ring would cost around $3.5 billion to build. In return, it estimates the system would provide $1.2 billion in annual benefits to the region.

The seawall, proposed by experts at Texas A&M University, is estimated to cost $5.8 billion and only have an annual benefit of $1 billion.

There is third-proposal by Rice University researchers called the "Centennial Gate".

But the Galveston County Daily News says the report does not make recommendations about how the state should move forward with storm surge protection measures.
