A longstanding feud between North Wildwood and the state Department of Environmental Protection over how to best address the immediate threat posed by the Atlantic Ocean continued this month, with the city’s mayor and the commissioner of the state agency trading letters expressing disagreement over what should be done this winter to address a serious shore protection problem.
