9.0 TRANSPORTATION MANAGEMENT PLAN
 Street lighting improvements
 Pump station improvements
Short-term Closure
A complete direction closure consists of prohibiting any traffic by public
motorists from entering or exiting the roadway in a defined direction
of travel (i.e., northbound or southbound) for an established length
construction zone and quantitative duration. In the case of the north-south
thoroughfares, this closure could be applied in both the northbound and
southbound directions of travel. Although not anticipated to be needed
often for the undergrounding program, if necessary, these closures could
span a maximum distance of one to two blocks of roadway at a time and
be restricted to a weekend time frame. In the case of the main east-west
arterials and the local residential, commercial or mixed-use roads, the need
for their closure to traffic or availability for a detour depends on the width of
the road. This is further evaluated below.
9.4 General Project Schedule and
Construction Sequence
The undergrounding of overhead utilities, namely electrical and
communication (FPL, AT&T, Comcast), is planned to occur in four phases
with starting dates from 2020–2023. Additionally, other improvements may
occur during the same time as the undergrounding. These improvements
could include the Village’s CIP, the Village’s stormwater master plan
improvements, and Miami-Dade County WASD watermain replacement.
The Village’s CIP improvements are small-scale projects planned to occur
during each year of the program and may be performed in conjunction
with the undergrounding. The Village’s stormwater master plan is a 10-year
phased program of improvements. The Village is considering accelerating
those improvements to coincide with the undergrounding program. Miami-
Dade WASD watermain improvements are planned to occur in conjunction
with the undergrounding program and be confined to the undergrounding
phase project area during any given year. These improvements were
considered when recommending transportation management options.
The following table has the anticipated construction sequence. See also
Chapter 6 of this master plan.
The initial construction activities in any given phase will include conduit
construction by a mixture of open cut trenches and directional boring
along with the installation of equipment and cabling. The final six months
of any given phase will include the removal of the existing overhead poles
and wires. Therefore, there will be an overlap when adjacent phases will
experience construction impacts potentially requiring road closures near
each other.

Since the focus of the program is the underground conversion of overhead
utilities and known large infrastructure programs, private construction
projects (homes and businesses) are not currently included in the major
work elements, but could have some impacts to traffic behavior in
the Village.
