HARBOR SYSTEM MASTER PLAN - City and Borough of Sitka

With the above noted damage, the service life of the components is reduced to 20 years, or less. The
power and lighting systems require substantial rehabilitation within the next five years.
Also note that the “Marine & Boatyard” shore-tie pedestals utilize digital revenue meters. Again, the
CBS Electric Department prefers Form 1S meters as noted previously in the Findings for Thompson
Harbor. And note that the lighting on the pedestrian gangway is damaged, leaving the gangway with an
inadequate amount of illumination.

Sitka Harbor System Master Plan

Existing Systems
The electrical systems at Crescent Harbor
consist of power distribution, shore-tie
pedestals, and lighting. Power is provided
for most of the vessels with illumination
of all of the facility. Communication land
lines provide telephone to vessels where
requested. These electrical systems were
installed when the electrical systems were
renovated in 2005.
Power Distribution System:
The power for the Crescent Harbor is
provided from two locations along
Lincoln Avenue. One utility service is
positioned to route power down the
gangway at Finger Float No. 2 and
distribute to Finger Float Nos. 1, 2, 3, &
4, as well as the main float. Power from the second utility service is routed down the gangway at Finger
Float No. 4, distributing to Finger Float Nos. 5 through 7. The feeders to the floating docks are all
protected by circuit breakers mounted in panel boards near to the approach end of the gangways. There
are no utility revenue meters at the service circuit breakers.
The utility service for Float Nos. 1, 2, 3, & 4 is
delivered at 480Y/277 volts using three separate
Type W cables routed through raceway beneath
the gangway. Each feeder is connected to a
substation located along the shore side of the
main float, at the head of each of the first three
finger floats. The substations reduce the utility
power to a usable rating of 208Y/120 volts. One
feeder circuit from the substation at Finger Float
No. 3 serves the panel board near the foot of the
gangway at Finger Float No. 4. This panel feeds
the shore-tie pedestals on Finger Float No. 4.
The utility service for the remaining floats is also
delivered at 480Y/277 volts to a terminal box and
then to a substation near Finger Float No. 5. This service feeder utilizes two Type W cables also routed
beneath the gangway in raceway to the floating dock. This substation again reduces the power to a
usable rating of 208Y/120 volts.
