Through a series of meetings with the Village, FPL, AT&T, Comcast,
and other stakeholder utilities, Kimley-Horn has assembled general
guidelines for design criteria to be used throughout the implementation
of the undergrounding program. These guidelines are not intended to
be all inclusive, or the only criteria to be followed during the design and
construction of the overhead to underground conversion improvements.
They are intended as guidance only for the design of the physical location
and placement of conduit and equipment and do not govern the detailed
electrical or communications network design that will be performed by FPL,
AT&T, and Comcast. This criterion is intended to be used as guidelines
during the implementation of the program so consistency in design and
construction can be realized over the life of the program. The criteria are
based on the assumption that all of the overhead utilities in the Village will
be converted to an underground location. They do not contain any criteria
for a hybrid system conversion that consists of partially overhead and
partially underground distribution components. A summary of this criteria
and conceptual design follows below.
5.1
General
The following codes and standards, as applicable, shall govern the design
of the improvements:
 Village of Key Biscayne Code of Ordinances
 Standards Applicable to Public Right-of-Ways and Easements
Within the Village of Key Biscayne
 Miami-Dade County Code of Ordinances
 Florida Department of Transportation Manual of Uniform Minimum
Standards for Design, Construction and Maintenance for Streets
and Highways (commonly known as the “Florida Greenbook”),
latest edition
 Florida Department of Transportation Design Standards
 Florida Department of Transportation Standard Specifications for
Road and Bridge Construction, latest edition
 Florida Building Code, latest edition
 National Electric Code (NEC), latest edition
 FPL Distribution System Standards, latest edition
 AT&T and Comcast System Standards, as applicable
There are some unique characteristics to the Village that also influence the
design criteria for the program. These are described in greater detail in the
following section. Development of the Village began in the early 1800s,
however, it wasn’t until the late 1940’s where we start seeing official plats
recorded and right-of-way widths start to develop. Typical of development
during this era is the prevalent use of narrow right-of-ways for public streets
and utilities. This creates unique issues for the undergrounding program.
Generally, it is desirable to install underground infrastructure on a roadside
shoulder versus under pavement. This allows for a simplified installation at
a lower cost than utilities installed under pavement. While some areas of
the Village have wide right-of-way with plenty of shoulder area to work in,
some areas of the Village are fully developed in that parallel parking, curb,
and streetscape have been installed that effectively eliminates any swale or
shoulder area. In areas that do have a small amount of roadside shoulder,
