12.0 OVERALL PROGRAM OPINION OF PROBABLE CONSTRUCTION COST
» Improvements by the Miami-Dade Water and Sewer
Department: The Miami-Dade Water and Sewer Department
(MDWASD) owns and maintains the water and sewer
distribution and collection infrastructure within the village
limits. The Village completed a septic-to-sewer conversion
program approximately 10 years ago where the customers
within the Village still using septic tanks had sewer mains
installed fronting their properties to connect to the sanitary
sewer system. As part of this program, MDWASD also
replaced any AC water distribution pipes within the septic-
to-sewer project area. However, there are still portions of the
Village where AC pipe remains that were not on septic, and
therefore, were not impacted by that project. Coordination
with MDWASD to replace this remaining AC pipe is ongoing,
and if the MDWASD were to coordinate its replacement
with the Village’s undergrounding program and where the
two projects impact the same roadways, the cost of milling
and resurfacing those roads could be shared between the
two programs. Because MDWASD has not established any
funding for this program at this time, we cannot quantify any
estimated savings that could be realized.
» Raising of Low-Lying Streets: Some of the costs related
to milling and resurfacing, including the above referenced
pavement cost sharing credits, could be funded by a program
to raise low-lying roads within the Village. Currently several
roads in the Village are low enough and experience minor
flooding during king tide events, even when no rainfall has
occurred. Raising these low-laying roads will reduce the
frequency of tidal flooding and help the drainage system
function during storm events by providing additional head
on drainage wells discharging water. Village staff expressed
interest in this program, but no funding for such a project
has been established, therefore we have not quantified any
estimated savings related to this program.

Volume Pricing for Pavement Milling and Resurfacing:
This program also offers the opportunity for the Village to take
advantage of volume pricing related to the milling and resurfacing
costs associated with large-scale paving programs. Thus, the
following could be considered:
» Postponement of milling and resurfacing until multiple
phases of undergrounding have been completed. After
undergrounding and other proposed infrastructure projects,
identified above, in given phases are complete, the milling and
resurfacing work can be subsequently bid and awarded by
the Village (i.e. two or three phase areas per bidding cycle).
Trenches and bore pits would be repaired to grade after
conduit installation with final milling and resurfacing to occur
later under a separate contract administered by the Village.
» Milling and resurfacing work could occur at night to minimize
traffic impacts to residents and increase paving efficiency.
12.9.4 Offsetting Revenues, Credits, and/or
Grant Funding
The Village may be able to offset some of the project construction cost
through various revenues, credits, or grant funding opportunities. This
would ultimately result in a lower net cost realized by the Village for the
program. These opportunities include the following:
 Sales Tax Savings: The direct purchase of communications
conduit and other necessary materials for the duration of the
program for which the Village will realize a sales tax savings.
 Additional credits or financial contribution from the utility
owners: There is a benefit each utility owner realizes in avoided
storm recovery efforts after an underground conversion is
complete. Currently, only FPL offers a credit (GAF Waiver) for this
benefit. The Village should continue to explore ways the utility
owners can participate in offsetting the cost of the program
based on the benefits they will receive. This can take on the
form of enhanced credits, no cost system betterments, etc. In
our experience this negotiation will delay the project, prevent
conversion, and ultimately pole removal.
 Broadband Infrastructure Revenue. The Village could decide
to use the program as an opportunity to assist in the installation
of another communications service provider to provide property
owners with another option for services beyond the legacy
