VILLAGE OF KEY BISCAYNE UNDERGROUNDING OF UTILITIES — MASTER PLAN with electrical lines. There are approximately 16 pole-miles of overhead infrastructure and 12 miles of underground infrastructure within the Village limits. Much of the overhead utility infrastructure is located in rear yard easements between street blocks within the single-family residential areas on the west side of Crandon Boulevard and multi-family areas on the east side of Crandon Boulevard. Underground infrastructure is often located within the public right-of-way of the Village. The master plan considers the various aspects that make the Village unique, such as zoning and land use designations, traffic, general topography and soils, types of underground infrastructure that exist, and plans for other future infrastructure improvements. Future infrastructure improvements include projects planned by the Village of Key Biscayne, Miami Dade County Water and Sewer, Miami Dade Traffic, and Hotwire Communications. Each of these considerations play a role in how the overall program will be executed. the Village can be replaced with Village owned custom lighting or with FPL owned and maintained light poles and fixtures provided under FPL’s street lighting program, included in their LT-1 Tariff. Phasing and Sequencing Plan Development The master plan provides a recommended phasing and sequencing plan for the implementation of the undergrounding program. This plan provides overall guidance of timing and sequence, but adjustments may be needed in the future to account for changes in technology, various utility and stakeholder requirements, and changes with other work programs within the Village during the implementation of the undergrounding program. Timing and sequencing should be reviewed at the time of design for each phase so any necessary adjustments can be made. Design Criteria and Conceptual Design Description Development Through a series of meetings with the Village, FPL, AT&T, Comcast, and other stakeholder utilities, Kimley-Horn assembled general guidelines for design criteria for the undergrounding program. These criteria are intended as guidance for the design of the physical location and placement of conduit and equipment so that consistency in design and construction can be realized over the life of the program. They do not govern the detailed electrical or communications network design that will be performed by FPL, AT&T, and Comcast. Network design by the utility owners will be performed based on their then-current design standards. Utility owners and stakeholders participated in workshops to review design requirements for the proposed underground infrastructure, define significant equipment needs to implement the program, and determine their approximate locations. The Village is currently implementing a street light program to install new light poles and fixtures. The undergrounding project will impact a significant number of street lights within the Village that are currently mounted to FPL- owned utility poles that will ultimately be removed.
