Details were announced Monday by Rice University, which led a team of researchers focusing on better hurricane preparations following the costliest natural disaster in Texas history.
Authorities have said Ike, which slammed Galveston on Sept. 13, 2008, caused more than $29 billion in damage. More than three dozen people died.
The Houston Endowment funded the study, which also recommends more levees for Galveston and creating a 130-mile-long coastal recreation area for wetlands to act as natural flood barriers.
