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
