VILLAGE OF KEY BISCAYNE UNDERGROUNDING OF UTILITIES — MASTER PLAN
12.8.6 Sidewalks (Safe Routes to Schools) 12.9 Cost Reduction Opportunities
The budget for this project has been previously established by Village
Council with hopes that costs savings could be realized by incorporating
this project into the undergrounding of utilities project. Additional sidewalk
improvements throughout the Village have not been contemplated in
this OPC. This OPC was prepared based on the understood goals and objectives
of the program, including conversion of all overhead utilities to an
underground location within the Village municipal limits. As a benefit to
the Village, this master planning effort explored several cost reduction
opportunities that could be considered by the Village. However, these
opportunities may require the goals and objectives of the program be
altered, variances from the Village Code of Ordinance requirements
be issued, or offsetting revenue and/or grant funding be applied to the
program. A summary of such options is presented below:
12.8.7 Beautification
Acknowledging the guidelines established by the Village of Key Biscayne
Landscape Management Plan, anticipating the spatial constraints
associated with varied adjacencies, and projecting budgetary mindfulness,
the landscape strategy for integration of utility interventions (a.k.a.,
electrical and communications equipment), utilizes a series of principles
rather than a prescriptive formula to guide placemaking efforts within
the public realm. A process-oriented approach to implementation will be
coupled with the guiding principles of Species Diversity, Site Specificity,
Layering, and Blending in order to integrate these man-made interventions
within a natural context. The costs associated with screening the utility
interventions have been included in the overall underground conversion
costs at $1,000 per property. This figure can be broken out and increased
or decreased as required by the Village.
12.8.8 Stormwater Improvements
As described in Chapter 4, the Village hired a consultant to prepare a
master plan for the implementation of the Village’s drainage improvements,
which includes upgrades to stormwater pump stations and gravity drainage
wells. Because the improvements proposed by this drainage master
plan are widespread, Kimley-Horn has been asked to incorporate these
improvements into the undergrounding master plan to realize efficiencies in
constructing them at the same time. The Tier 2 improvements identified in
the master plan are extensive. The cost for these improvements developed
by this master plan are included in our OPC. Although the Village has setup
a stormwater enterprise to pay for drainage improvements, the Village
currently does not have the budget to incorporate all the improvements
identified in this master plan.

12.9.1 Construction Methods
The overall program cost for undergrounding the existing overhead utilities
could be reduced if specific construction techniques and/or sequences are
considered. This could be accomplished in several ways.

Pavement Milling and Resurfacing Cost Sharing: As outlined
in other sections of this Master Plan, additional infrastructure
projects are proposed throughout the Village over the expected
duration of the undergrounding program including drainage and
water main projects. These infrastructure projects are anticipated
to incorporate milling and resurfacing of their work area. For areas
where these projects and the undergrounding conversion project
will be in the same location, the cost of the required milling and
resurfacing could be shared between the participating entities (i.e.,
Village, Miami-Dade Water and Sewer Department, etc.). Details
regarding the assumptions that were made for each utility owner
with significant infrastructure projects within the Village are noted
below:
» Stormwater Master Plan Implementation: The Village
recently completed the preparation of a stormwater master
plan that proposes numerous infrastructure improvements
to the Village’s stormwater management systems within
the Village. The proposed stormwater management system
improvements could be implemented in conjunction with the
undergrounding project, and where the two projects impact
the same roadways, the cost of milling and resurfacing those
roads could be shared between the two programs.
