All <strong>of</strong> the shore-tie pedestals are mounted on a polyethylene pad on the deck with a supporting structure<br />
integrated with the floating dock structure. The pedestals are mounted approximately two inches from<br />
the bull rail. They are mounted between stall floats thus facilitating a vessel directly on each side.<br />
Upl<strong>and</strong>s Lighting:<br />
The area near the approach dock <strong>and</strong> gang way is illuminated with a pole mounted luminaire. The<br />
luminaire is cast aluminum, painted inside <strong>and</strong> out. The light source is high pressure sodium. The pole<br />
is painted, galvanized steel mounted on a concrete base. The lighting is powered from the Substation<br />
BC along the main float <strong>and</strong> controlled by the daylight/night (photoelectric cell) type sensor.<br />
The parking area is illuminated with roadway type fixtures mounted on tapered round poles. The light<br />
sources are high pressure sodium. These luminaires are separately controlled with integral<br />
daylight/night type sensors.<br />
Gangway Lighting:<br />
The interior <strong>of</strong> the covered gangway is illuminated from<br />
fixtures mounted at the peak <strong>of</strong> the covering canopy. The<br />
luminaires are surface mount type with enclosing acrylic<br />
lenses. The light source is high pressure sodium. This lighting<br />
is powered from Substation BC along the main float <strong>and</strong> is<br />
also controlled by a daylight/night type sensor.<br />
Harbor Lighting:<br />
<strong>Sitka</strong> Harbor System Master Plan<br />
Condition Inventory<br />
The main floating<br />
dock is illuminated<br />
from fixtures<br />
mounted on posts<br />
fastened to the dock<br />
structure. The<br />
luminaires <strong>and</strong> posts<br />
are similar to those<br />
on the upl<strong>and</strong>s near<br />
the approach. These<br />
are powered from<br />
Substation BC <strong>and</strong> controlled by the adjacent daylight/night<br />
controller.<br />
The finger floats are illuminated from fixtures mounted to the<br />
tops <strong>of</strong> the shore-tie pedestals. In some areas where shore-tie<br />
pedestals are not installed, bollard type posts similar to the<br />
shore-tie pedestals are used. The<br />
fixtures utilize high pressure sodium<br />
light sources.<br />
The lighting for portions <strong>of</strong> the main float <strong>and</strong> each finger float are<br />
individually fed from the substations along the main float. A controlling<br />
contactor is mounted near the panel for each finger float. The control for<br />
the contactors is integrated together with a single daylight/night sensor<br />
controlling all <strong>of</strong> them.<br />
