VILLAGE OF KEY BISCAYNE UNDERGROUNDING OF UTILITIES — MASTER PLAN
A review of the soils maps reveal that the Village of Key Biscayne is
underlain by two distinct soil classifications:


Canaveral Sand Complex
Urban Land Complex
Urban Land Complex is not a soil type, but rather an area that is unable
to be accurately classified into a soil type due to the amount of existing
development. This leaves Canaveral Sand as the only distinct type of soil
recorded in the Village.
The Canaveral series is a deep, poorly- to moderately-drained soil with
sand and shell fragments found throughout. The soil can be found along
the coast on low dune like ridges (National Cooperative Soil Survey, 2014).
On the island, the Canaveral series is found in a few pockets near the
center of the Village.
This soil depicts marine environments with sand and shell deposits found
throughout. Major rock material is not identified in the Village and during
conduit construction this is important for employing the proper machinery
and methods. Because the classification of soils identified by NRCS maps
for the Village is general in nature, we recommend that soil testing be
conducted throughout the phase areas during design to better define the
local soil characteristics.
4.3 Existing Utility Infrastructure and
Future Infrastructure Planned Improvements
To develop a master plan for this project, it is important to understand
the existing utility infrastructure that will remain in service during the
implementation process and remain after the completion of the program. It
is also important to identify other significant construction projects that may
occur during the implementation phase of the program so that work can
practically be coordinated. If these projects are identified ahead of time,
their impacts can be limited to the extent possible.
Kimley-Horn coordinated with the stakeholders listed below to obtain
readily available information regarding the existing utility infrastructure within
or near Village limits:

A description of the type of data collected from each of these stakeholders,
as well as how it impacts the undergrounding program, follows below.
4.3.1
Village of Key Biscayne
The Village of Key Biscayne provided atlas level data of their infrastructure
to Kimley-Horn for review. The Village owns and maintains the following
underground infrastructure that will need to remain after the completion
of the program and remain in service during the implementation of the
program:


Stormwater collection and transmission
Electrical street lighting
The consultant team coordinated with representatives from the Village
of Key Biscayne Manager’s office, as well as Public Works regarding
proposed infrastructure projects planned throughout the Island. The
Village provided project information for its proposed Capital Improvements
Program (CIP). Based on information provided, there are proposed projects
throughout the Village. These projects can be generally categorized as the
following types:






Drainage improvements
Stormwater pump station improvements
Street lighting improvements
Roadway improvements
Landscape improvements
Recreational projects
