VILLAGE OF KEY BISCAYNE UNDERGROUNDING OF UTILITIES — MASTER PLAN
Existing underground AT&T communications manhole and pad mounted pedestal in Key Biscayne
46
Multiple VHubs and LCPs can be served by a single power supply
and located in a common easement. In locations with multiple
VHubs, an easement larger than 10'x10' may be required. A fiber optic service pedestal or vault can serve up to four homes.
Conduit is required from the pedestal to the service point at the
home if a fiber optic system is installed.
Cables containing greater than 96 fiber strands will require
24"x36" vaults. Cables containing less than 96 strands can be
accommodated in 17"x30" vaults. Higher fiber count cables will be
found generally closer to node locations. Fiber counts reduce as
the strands radiate from the nodes in the service areas. Vaults are
to be located off of the roadway. Conduit is required for coaxial service cable to the home. A coaxial
cable service pedestal can serve up to eight homes but Comcast
prefers to design for approximately four homes. Coaxial cable
service lengths should be kept under 150 feet in length.
Equipment may be located in the right-of-way if sufficient clear
zone requirements are met (FDOT or AASHTO, as applicable).
Service pedestals are not required in areas served with 24"x36"
vaults. All service connections can be made directly from the vault. Pedestals require one foot of clear distance around all sides for
access and maintenance.
Service pedestals and vaults will be installed generally in the
same easement as the electrical equipment. They can also be
installed in the public right-of-way as long as the required roadway
clearances are met. These pedestals and vaults will then provide
communications service to the individual facilities. For pedestals not
sharing an easement with FPL equipment, Comcast prefers a 5'x5'
easement. Pullboxes will be required at regular intervals to facilitate cable
pulling and slack cable storage if long runs exist between service
vaults/pedestals.
Conduit and pullboxes are to be NEC compliant for
communications service and orange conduit shall be used.
Equipment, integrated pedestal vaults, and cabling will be provided
and installed by Comcast. Conduit and pullboxes will be furnished
and installed by the Village’s contractor.
