5.0 DESIGN CRITERIA AND CONCEPTUAL DESIGN DESCRIPTION
5.3.2
AT&T
AT&T provides communications service to the Village through a network
of copper cables. Much of the trunk line already exists in an underground
location to their distribution center on Westwood Drive. Distribution
of service is accomplished to most homes and businesses through
underground to overhead transitions at the overhead radial line locations.
AT&T intends to continue service to the Village through a copper system.
They indicated they have plans to upgrade to fiber service in the future
but they are not prepared to make this conversion in conjunction with the
undergrounding program.
AT&T will perform the communications network design for the program
with Kimley-Horn developing the supplemental conduit plans to aid the
Village’s contractor in installing the conduit for the project. AT&T has
communicated the following general guidelines related to the design of the
improvements.
Existing AT&T cabinets and electrical service in Key Biscayne
Upgrades will be built into the design that include new feeder ties and
looping that will provide enhanced reliability to the Village. Kimley-Horn’s
recommendation to the Village is to allow these upgrades to be
constructed, but at no additional cost to the Village since Key Biscayne
should not subsidize system improvements desired by FPL. Costs related
to upgrades should be clearly identified during the development of the
Binding Cost Estimates for each phase so these costs can be credited
along with the applicable Government Adjustment Factor (GAF) Waiver.
 Main underground trunklines and equipment shall remain in service
(including existing SAIs and CEVs)
 The existing underground trunk line shall be reused. Distribution of
service will be converted to underground through connection to the
trunk line at existing trunk line manhole locations
 Service pedestals will generally be installed in the public right-
of-way or the same easement as the electrical equipment.
These pedestals will then provide communications service to the
individual facilities. For pedestals not sharing an easement with FPL
equipment, AT&T prefers a 5'x5' easement.
 AT&T prefers major equipment easements to be 10'x10' for their
future fiber equipment needs
 Equipment may be located in the right-of-way if sufficient clear
zone requirements are met
 Pedestals require one foot of clear distance around all sides for
access and maintenance
 Pullboxes will be required at regular intervals to facilitate cable
pulling and slack cable storage. AT&T prefers 24"x36" and 30"x48"
pullboxes. Pullboxes are to be located outside of the roadway
surface. When required, pullboxes can be placed in the paved
surface and in this case, will be required to be H-20 load rated.
