DESCRIPTION A 100 x 100-ft. concrete pad was constructed adjacent to the
Mix~-Fill Building in the southwest corner of the island.
The pad has a minimum
thickness of 7 inches and is sloped 1 percent to one side to a drainage ditch which
is channeled to a rip-rap outfall in the ocean. Six power outlets for floodlights
are provided at the periphery of the pad. Power is supplied from the Mix- Fill
Building bus. One 3/4-inch hose bib for saltwater is located at the edge of the
pad; a second 3/4-inch bib provides freshwater. The water supply is piped
from the Mix-Fill Building area.
