The ocean breached the dunes in seven places – from Lyman Avenue to Downer Avenue – during Wednesday's coastal storm, the Mantoloking Office of Emergency Management has confirmed.
"Ocean water pushed through and brought significant amounts of water and debris onto Route 35," the borough's OEM office reported in a post to its Facebook page.
After the ocean breached, the wind shifted to the southwest, causing "significant" bayside flooding, the office said.
Flooding reached the top step of the borough hall building on Downer Avenue and was measured at 2.9 feet above normal at Old Bridge Street.
"We need to see what happens during the next two tidal cycles to see about access [Friday]," the post said.
A determination on access for borough residents will most likely be made Friday morning.
