6.0 PHASING AND SEQUENCING
In general, capital projects that are expected to have significant roadway
impacts should be constructed in conjunction with the undergrounding
program to the greatest extent practical. However, a balance needs to be
struck between maximizing projects within the undergrounding project
schedule and overwhelming the community with construction impacts.
Additionally, projects that are required due to public health, safety, and
welfare needs should be implemented quickly and not necessarily delayed
to coincide with a particular phase of undergrounding.
Many of the Villages projects are non-bond funded projects, are relatively
small in scope, and/or are located such that roadway impacts are
minimal or have a brief schedule duration. Therefore, these projects are
recommended to be constructed in accordance with their previously
planned programming schedules. Some projects impacted by the
undergrounding, such as landscape improvements, traffic calming,
sidewalks, and street lighting should be delayed if possible to coincide with
the undergrounding schedule. This will allow for additional restoration cost
sharing benefits.
There is also a recent stormwater master plan that identifies significant
improvements but lacks funding at this time. Projects identified in this plan
are to be funded by the Stormwater Enterprise Fund, however, that fund
is inadequately funded. The Village recently engaged a financial consultant
to develop new rates to begin to fund these projects over the long term.
If financing permits, it would be extremely advantageous to perform these
stormwater improvements during the undergrounding program, thus cost
sharing restoration efforts. This would also decrease the impact to the
residents in the long term. In our experience, most resident complaints
come from people who live in areas impacted by undergrounding and
capital projects at the same time. Provided the funding enables these
improvements and the resident impact is managed properly, this master
plan recommends that these infrastructure projects be constructed in
conjunction with each undergrounding phase.
Village of Key Biscayne Beach Renourishment Program
The Village conducts an ongoing Shore Protection program to protect the
coastline. While there are several projects anticipated within this program
that will occur during the span of the undergrounding project, we do not
anticipate much coordination will be required between the programs, since
the beach renourishment project is not in areas undergrounding work will
not be performed. Beach renourishment projects that involve truck hauls
should be coordinated to reduce the impacts of additional traffic volume
through the work zone.
Miami-Dade Water and Sewer Department
Watermain Replacement
As discussed in the Data Collection section of this master plan, Miami-
Dade Water and Sewer Department (WASD) does not currently have a
formalized program for watermain replacement within the Village. However,
at the request of the Village, they are willing to entertain the opportunity
to replace aged watermains during each phase of the undergrounding
program. There is currently no budget available to perform this work,
however, WASD will review the Village’s proposal of replacement and
consider adding it to the budget for the next fiscal year. This master
plan’s recommendation is to focus on the known watermains consisting
of asbestos cement pipe as requested by the Village. There are other
watermains identified by WASD as being made of an unknown material.
Secondarily, we recommend review of those locations to determine the
most cost-effective approach to their replacement. Because physical
investigation will be required for these unknown watermains, timing of their
replacement may not coincide with the undergrounding program.
If the County does develop a program of watermain replacement during the
course of the undergrounding project, additional cost sharing opportunities
could be explored through deferral of milling and overlaying activities until
both undergrounding and watermain work is completed.
6.2.2
Traffic Impacts
The sequencing recommendations for this program are also influenced
by the desire to reduce traffic impacts to the highest degree possible.
A detailed discussion regarding an overall traffic management plan is
discussed elsewhere in this master plan but on a grander scale, the
beginning of a mitigation plan for traffic impacts begins with sequencing
individual phases.
