The majority of debris was removed by October 1979. During this entire period, rehabilitation efforts were unimpeded. Most of the concrete rubble (27,000 cubic yards) generated by the destruction of buildings and structures was used to extend the north point of Medren. This was deemed necessaryto protect the future use of the new deep-water pier constructed under the TTPI Rehabilitation Program. Removal of huge piles of scrap metal and hazardous debris from the northern tip of the island had altered the water flow, and sand was being deposited in close proximity to the pier’s docking areas. The north point extension was designed to redirect the flow to preclude the buildup of sand (Figure 5-32). The north point buildup was highly successful for this purpose, and countless man-hours and equipment hours were saved by not transporting this rubble to lagoon dump site A. A total of 14,028 cubic yards of other debris (including 160 Master Index items) from Medren was dumpedin the lagoon. There were 73,528 cubic yards of debris removed, including 32,500 cubic yards removed by the scrap contractor and 27,000 cubic yards used as shore protection.!!7 Medren after cleanup is shownin Figure 5-33.
