It should be noted that no cost estimation services are included in this Scope of Services for the <br />implementation of the SSMs. It is assumed that AAF will fund all necessary improvements. If such an <br />agreement is not reached with AAF and the County requests assistance in preparing the SSM cost <br />estimates, a separate Work Order will be prepared to provide those services. <br />The following subtasks outline the requirements for submitting a Quiet Zone request to FRA. <br />Subtask 2.1 - Delineate Study Area <br />The initial step in this study is to delineate the boundary and elements of the study area for the Quiet <br />Zone Analysis. A number of items influence the selection, number and location of railroad crossings to <br />be included in the study area. This list includes: <br />■ Minimum Quiet Zone length <br />■ Budget considerations <br />■ Neighborhood interest <br />■ Noise Study Evaluation <br />■ Population density <br />■ Safety considerations <br />Minimum Quiet Zone length, budget for the analysis and improvements, and neighborhood interest will <br />be obtained through discussions with the County and other interested parties. Noise study data will be <br />obtained from the documents provided by AAF (and confirmed under Task 1) The population density <br />will be obtained through a GIS analysis of land adjoining the rail lines. Safety considerations will be <br />developed through observation and evaluation, and assist in selection of the treatment of each crossing <br />to be included in the Quiet Zone. <br />Deliverable: The result of this task will be the development of a map of the recommended Quiet Zone <br />study area, inclusive of road and rail infrastructure inventory within the study area. The map will be <br />provided to the County electronically for review and comment prior to proceeding with the subsequent <br />tasks <br />Subtask 2.2 - Update Train and Railroad Grade Crossing Data within the Study Area <br />Task 2.2 will consist of a data collection and data entry effort. The data listed below will be obtained <br />from a combination of the grade crossing inventory maintained by the County, Florida Department of <br />Transportation (FDOT), diagnostic field evaluations performed in July 2014, and the FRA, and will be <br />updated as necessary using operating data obtained from AAF's EIS report or from correspondence with <br />AAF on train frequency, speeds and lengths. <br />Data to be compiled includes: <br />Train Data: <br />■ Number of trains <br />■ Type of trains (freight or passenger) <br />■ Schedule/speed/length of trains <br />Grade Crossing Data: <br />■ Number of lanes <br />■ Vehicular traffic volumes (using available data from Indian River County and/or FDOT) <br />■ Type of warning device in use <br />CDM A_3 sss doc <br />
