WOODBURY - A $700 million federal plan calls for raising more than 4,000 South Shore homes and roads.

Details are being finalized by the Army Corps of Engineers, but the plan would put money toward elevating homes in nearly a dozen South Shore neighborhoods at no cost to the homeowners.

Costs would be covered by some of the $51 billion Sandy aid bill approved by Congress.

The Army Corps of Engineers plans to release its full plan this winter. If it is approved by federal, state and local governments, it will take several years to complete.
