BAY HEAD - Residents near Bay Head fear a rock wall being built on the barrier island will actually cause flooding in Mantoloking.

Homeowners of Bay Head chipped in to help pay for the more than $2 million wall project that calls for making an existing rock wall higher and longer. However, residents of Mantoloking worry the improved wall will push floodwater their way.

As a result, some residents have asked the Department of Environmental Protection for permits to extend the wall onto their properties too.

The rock wall in Bay Head will be 18 feet high.
