utility conflicts. This can be avoided by having FPU gas main replacement follow the installation of the Town’ s undergrounding of utilities.
According to Town staff, there is precedence for shared road restoration costs with the gas company even if this restoration is performed by the Town long after the gas company has completed their work. For past projects, the gas company has foregone the Town-required milling and resurfacing in areas where Town construction activities were also concurrently occurring and instead provided the Town with funds to cover their fair share of the restoration. The Town would then repave the project area using those funds in addition to their own.
The gas company plans to convert their rear yard gas mains to the front street. Because of this conversion, there is a high risk that decisions made in the field by gas company contractors could result in a situation where the available corridor for the electric and undergrounding conduits is taken by the gas
main. This could result in schedule delays and added expense to the undergrounding program.
Kimley-Horn’ s recommendation is that to the greatest extent practical, the gas main replacement work be conducted after the installation of the undergrounding conduits. Depending on schedule availability, the gas main could be installed in conjunction with the undergrounding phase or at some point afterwards. If the gas company’ s federal mandate scheduling restrictions dictate that the gas main be installed in advance of the undergrounding work, we recommend that the location of the proposed gas main be highly coordinated with the Town to allow room within the right-of-way for both the gas main and the required undergrounding infrastructure.
Florida Department of Transportation( FDOT) Work Program
The only FDOT project currently planned that will be in progress during the implementation of the undergrounding construction program is the replacement of the Southern
Boulevard Bridge. This work is expected to commence in 2017 and be completed by 2021. This project is located in the Phase 2S area of the undergrounding program, which will begin in May of 2018 and be completed in late 2019. It is understood that the Flagler Memorial Bridge project is anticipated to be completed in 2017.
The initial activities for the bridge replacement project will involve a substantial amount of in-water work as the FDOT constructs a temporary bridge. This work will be occurring at the same time as Phase 2S. As the details of the activities in the FDOT work schedule become finalized and available, and the contractor for Phase 2S is selected, the detailed traffic control plans for this area will need to be closely coordinated.
There are no other FDOT planned activities in their work program that would impact the undergrounding project at
this time.
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 the sequencing of the individual phases.
Traffic congestion is a source of much frustration in the Town. Because it is a community that was developed largely during a time that depended less on vehicular travel, the rights of way available for roadway lanes are already at their maximum capacity. Recent traffic study data revealed that most roads in Town operate at a Level of Service D or worse. This creates an environment for extreme congestion when any lane capacity is impacted by construction operations.
This master plan’ s recommendation is that the phases begin at the north and south extremes of the Town and work inward towards the center. In this manner, the bulk of the population
