Open fencing (posts with string) can help limit foot traffic within dunes and other sensitive areas, but does little to help trap sand within the dune. Installing open fencing usually does not require a permit.

Sand/snow fencing (wooden slats/pickets with wire) can help trap sediment adjacent to the dune system. If the opening between pickets/slats is at least 4 inches wide, or at least double the width of the picket, whichever is greater, a permit is not needed; all other fencing will require a permit from Maine DEP.

Cobble trapping fences may be installed where cobble regularly washes over a seawall and threatens private structures. These fences are permitted only in specific areas adjacent to cobble or gravel beaches and have developed areas between the building and the beach (such as lawn). Specific standards relating to these fences are included in Natural Resources Protection Act Chapter 305, 16C.

Be neighborly. Think about potential impacts on your neighbor’s property that may result from an activity on your property. At the same time, it may make sense to work with adjacent property owners if a common goal is found or regional approach is being adopted to deal with certain hazards.

In some cases on beaches and dunes, actions you might take could impact threatened or endangered species such as piping plovers. If these species are present, it's likely you have been made aware of this. In these cases, consultation with state and federal wildlife agencies will be needed before action can be taken.
