<br />McMahon Associates, Inc. (McMahon) is pleased to provide this proposal for traffic engineering services
<br />associated with the proposed improvements at the intersection of 271h Avenue SW with 211, Street SW, in
<br />Vero Beach, Florida. Specifically, this proposal is for services to prepare signal design plans for the
<br />intersection of 271s Avenue SW with 21st Street SW (project intersection).
<br />This proposal is based on the assumption that all project baseline geometry, existing and proposed right-
<br />of-way, topographic, geotechnical, and sub -surface utility exploration (SUE) information necessary to
<br />complete the design will be provided by Carter Associates, Inc.
<br />The existing topography information will include existing above ground features and elevations for a
<br />minimum distance of 200' in the north, south, east and west direction of thestudy intersection. Field
<br />survey data, to be provided by Carter Associates, Inc., must include planimetrie survey delivered in
<br />CARD format and shall include horizontal location of edges of roads, curbs, gutters, sidewalks,
<br />pavement markings, surface features of utilities, signage, existing poles, landscaping trees and features
<br />within the project limits and within all right-of-way. Sufficient data will be provided to establish
<br />roadway crown elevations, roadway slopes, and elevations at the base of any new mast arm uprights.
<br />In order to provide the proper design for the traffic signal supports, subsurface soil information must be
<br />provided by Carter Associates, Inc. Soil borings will be obtained in the field by a Geotechnical Engineer,
<br />at all comers of the study intersection. The geotechnical information will be analyzed, and the project
<br />Geotechnical Engineer will provide a standard report. This information will be utilized for the design of
<br />proposed traffic signal mast amt supports and their foundations.
