Beach nourishment is the process of pumping sand onto an eroding shoreline to widen the existing beach. Sources of sand may include a nearby sandbar, a dredged source such as an inlet or waterway, or an offshore borrow site along the ocean floor. The widened shoreline provides increased defense from coastal storms and beach erosion protecting property, communities and infrastructure located along the shoreline. It is anticipated that this beach nourishment is designed for a minimum of five years protection before maintenance is required.

During construction, a project status map will be available at www.MoreBeachtoLove.com with updates on current construction areas and anticipated progress of work.
Typically, any given section of beach might be shut down for 4 to 6 days. To ensure public safety during this time, direct access to the beach in front of a given property will be prohibited. The contractor will install caution tape at crossovers that lead to the active construction area. Likewise, the contractor will install a temporary barrier on the northern and southern boundary of the active construction area to prohibit pedestrian traffic.
Equipment that is used includes: bulldozers, loaders, excavators, as well as, light plants, welding equipment, and other ancillary equipment. Construction typically occurs on a 24/7 basis. Dozers and loaders are equipped with back up alarms and lights. Outside the active construction areas, shore pipeline will be laid to allow for sand to be pumped from the nearshore pump-out station to the active construction area. This pipeline will run parallel to the beach. Pipelines may remain in place in front of individual properties for several weeks. However, sand ramps will be constructed over the pipelines to allow pedestrian traffic over the pipe.
