The system requires no pumps or energy to operate. At Hillsboro Beach, Florida the system was installed for a 3-year period at a highly eroding part of the beach where the shoreline historically had lost 25.2 ft. (-7.7 m) in 3 years. By the end of the 3-year period the shoreline in the 1-mile PEM project area had advanced 26.9 ft. (8.2 m), erosion had stopped, and the PEM area had accreted from R-monument line to MHW, to -5ft NAVD, and to DOC without the control areas to the North and South being negatively affected. ER -
