A 25-year North Carolina ban on concrete or other walls to block wave action is being tested.
The state House plans a vote Wednesday on legislation that would let the Coastal Resources Commission to test the effectiveness of coastal jetties to slow the erosion on islands along inlets.
The legislation would allow up to three test cases, no more than two of which would use public funds.
Supporters say the measure would protect inlets and development from encroaching surf. Environmentalists say jetties don't work and will cost millions of dollars.
The version which had already passed the Senate placed no limits on the number of projects.
