Palm Beach Undergrounding Master Plan COMPLETE MP Online-v4 | Page 32

The Palm Beach series is very similar to the Canaveral series in that it is a deep soil found on dune-like ridges and was formed in thick deposits of sand and shell fragments. The soil is well drained and is typically found on the eastern side of the Island, throughout. The Pomello Fine Sand series is a moderately well drained soil found in sandy marine sediments( National Cooperative Soil Survey, 2014). This is a sand that ranges from fine to coarse material and is found on the northern end of the Island, on the eastern side close to the beaches.
The Arents series consists of nearly level, sandy soils that are formed in thick layers of sandy fill material placed over low, wet mineral soils to make the land suitable for urban use.
These soils all depict marine environments with sand and shell deposits found throughout. Major rock material is noted at shallow depths only within the Cocoa series and during conduit construction this is important for employing the proper machinery and methods. Based on our experience with other projects on the island, isolated pockets of organic soils have also been encountered in the areas of the Canaveral series. For this reason, we recommend that soil testing be conducted throughout the phase areas during design to better define the local soil characteristics.
4.3 Existing Utility Infrastructure and Future Infrastructure Planned Improvements
To develop a master plan for the project, it is important to understand the existing utility infrastructure that will remain in service during the implementation process and remain after the completion of the program. It is also important to identify other significant construction projects that will occur during the implementation phase of the program so that work can be coordinated to the extent practical. If these projects are identified ahead of time, their impacts can be limited to the extent possible.
Kimley-Horn coordinated with the stakeholders listed below to obtain readily available information regarding the existing utility infrastructure within or near Town limits.
• yTown of Palm Beach
• yCity of West Palm Beach
• yCity of Lake Worth
• yTown of South Palm Beach
• yFlorida Public Utilities
• yFlorida Department of Transportation( FDOT)
• yFlorida Power & Light( FPL)
• yAT & T
• yComcast
A description of the type of data collected from each of these stakeholders, as well as how it impacts the undergrounding program, follows below.
4.3.1 Town of Palm Beach
The Town of Palm Beach provided atlas level data of their infrastructure to Kimley-Horn for review. The Town owns and maintains the following underground infrastructure that will need to remain after the completion of the program and remain in service during the implementation of the program:
• ySanitary sewer collection and transmission
• yStormwater collection and transmission
• yElectrical street lighting
• yTraffic signal operation
• yEmergency fuel systems for public facilities
• yPublic safety systems
The consultant team coordinated with representatives from the Town of Palm Beach( staff as well as the Town’ s Program Management Consultant) regarding proposed infrastructure projects planned throughout the Island. The Town provided project information for its proposed Accelerated Capital
Improvements Program( ACIP) as well as its“ Pay-Go” projects. Based on information provided by the Town, there are proposed projects throughout the island. These projects can be generally categorized as the following types:
• yOcean outfall abandonments
• yPaving and drainage improvements
• yStormwater Pump Station Improvements
• yWastewater pump station improvements
• yStreet lighting replacements
• ySignal and mast arm replacements / upgrades
• yLake Trail pathway improvements
• yRecreational projects
The ACIP projects are bond funded and must be completed by 2019. These projects will move forward independently of the Town’ s proposed utility undergrounding plan. In addition, a majority of the projects, with the major exception of the paving and drainage improvements, can be considered as“ stand alone” projects, as they are at isolated locations and will have little impact, if any, to the Town’ s proposed undergrounding construction.
In general, paving and drainage improvement projects will be performed concurrently with the Town’ s proposed undergrounding construction, with the exception being
