Local Flood Hazards

Because our Town is a barrier Island, when it rains during a high tide there is no place for the rainwater to disperse. Normally, this type of event is temporary in nature and when the tide goes out so will the water. Generally, these will not cause flooding to property, however if they do, contact your Building Official to see if measures may be taken to mitigate future loss.
