GEOTECHNICAL ENGINEERING & LAND SURVEYING SERVICES AGREEMENT
BETWEEN McMAHON ASSOCIATES, INC. & INDIAN RIVER COUNTY, FLORIDA
This is an amendment to the existing Professional Civil Engineering, Geotechnical Engineering and Land
Surveying Services Agreement (AGREEMENT) dated May 17, 2005, between McMahon Associates, Inc.
(ENGINEER) and Indian River County (COUNTY). This amendment addresses changes in "Section I — Project
Limits and Description", "Section III — Scope of Services", "Section IV — Time for Completion," and "Section V —
Compensation," of this AGREEMENT.
"SECTION I - PROJECT LIMITS AND DESCRIPTION" is being modified to incorporate the following:
Consultant services are required for the preparation of supplemental design survey, roadway design plans
with the design of improvements within the present contract limits of the intersection of SR-5/US-1 and CR -510
(Wabasso Road), in Indian River County, Florida, as last amended on October 16, 2007. The roadway
improvements identified by the COUNTY include the realignment of SR -510, east of US -1, 58 h Avenue and the
addition of 59`b Avenue Frontage Road, and consist of the following:
"SECTION III — SCOPE OF SERVICES" is being modified to incorporate the following:
The ENGINEER agrees to perform professional design and related services in connection with the project,
as required and set forth in the following:
B. Design Surveys
The ENGINEER shall provide supplemental design survey services necessary to support and facilitate
contemplated design and permitting activities associated with this supplemental portion of the project.
1. US -1 Baseline resolution, within the DESIGN LIMITS.
In a review of information obtained from the Florida Department of Transportation
(FDOT) from Genesis Map files, discrepancies in the previously defined baseline were
detected. Due to these discrepancies the project baseline needs to be field adjusted, and
the project plans require updating, as well.
2. Establish and update project wide horizontal and vertical control network for 58`h Avenue
and 59`h Avenue Frontage Road within the DESIGN LIMITS.
The project baseline work on 586 Avenue was included in the Pre -60% plan submittal,
prior to determining the right-of-way control survey. It was agreed by the COUNTY to
include the baseline, but revisions may be required. When the information became
available and was received, it was determined that there are minor offsets in the current
baseline requiring adjustments to the plans. The adjustments are required to roadway
plans, cross-sections, signalization and signing and pavement marking plans profiles.
The COUNTY has requested the addition of the 59`h Avenue Frontage Road to be
included with the project. Additional horizontal and vertical field control including DTM
survey will be established and the project plans updated to include this information.
3. Establish and update project information to delineate wetland areas within the DESIGN
LIMITS.
Within the project limits, several areas have been identified as potential wetland areas.
Only those potential wetland areas that are expected to be impacted by the project will be
identified. Once these areas are identified, the project will be updated to include the
wetland delineation, and each angle point/flag will be surveyed, and referenced to the
project's horizontal control.
B1. Right-of-Wav-Survev
The ENGINEER shall provide supplemental design survey to compile the accurate location of
property parcels in the vicinity of 58th Court and 58`h Avenue, south of CR -510 and west of 58"'
Avenue and east of the Indian River Farms Water Control District Canal No. Lateral -G, within the
DESIGN LIMITS.
The ENGINEER shall also provide for additional parcel sketches and legal descriptions for
properties along both 58th Avenue and US -1, which are not supported by the project right-of-way
model.
The ENGINEER shall also provide for additional parcel sketches and legal descriptions for
specific types of acquisitions, i.e., temporary construction easements (TCE), and for drainage areas
in right-of-way or easements (DE). The ENGINEER has been requested by the COUNTY to
prepare the various parcel sketches and legal descriptions for this project. Each individual
property may contain one or more types of these areas. The number of parcels and types will be
estimated, based upon the Pre -60% Roadway Plans, and the current modification of SR -510
alignment, east of US -1, and the estimate of the ENGINEER from an evaluation of cross-sections,
2
drainage design and anticipated retention pond locations and corresponding outfall impacts. In the
interest of time, and to assist the COUNTY with discussions with individual property owners along
the corridor, it may be necessary or required to prepare a parcel sketch with multiple revisions.
For those purposes, an estimate of 10% of the individual type of taking or easement will be
quantified as a "re -do." Below is a table of the total estimated project parcel sketches, and those
that have been established to require the different types of easements and the associated unit cost
that will be provided under Hourly Rate Components, in "Section V — Compensation."

There is currently available $38,250.00 for parcel sketches and legal descriptions that were based
upon a supported right-of-way model, and an additional3$ ,300.00 for parcel sketches and legal
description for properties unsupported by the right-of-way model. The total of the effort computed
above is8$ 2,800, less the available ($41,550.00), leaves a remaining value of4$ 1,250. This is the
effort required for this work. When the fee utilized equals 75%, the ENGINEER will assess and
3
advise the COUNTY, if the balance of the work can be accomplished with the balance of the fee.
If the work cannot be completed, the ENGINEER will notify the COUNTY, in writing, and make a
request for a supplemental agreement.
Cl. Geotechnical Investigations
AS DIRECTED BY INDIAN RIVER COUNTY, THE COUNTY WILL PROVIDE THE ENGINEER
WITH THE BELOW DESCRIBED SERVICES AS STIPULATED TO COMPLETE THIS PORTION
OF WORK FOR THE HEREIN DESCRIBED PROJECT.
The ENGINEER has received the Soils Conditions Survey for the project. In and along the
corridor, the Geotechnical Consultant identified muck/organic deposits. Due to these existing
conditions, additional borings will be required for, and to delineate: muck/organic deposits; plastic
soils, and other deleterious subsurface, particularly in fill -conditions in existing ditches/canals. In
addition, additional geotechnical investigations are required to determine potential slope
instabilities in step cut areas, particularly adjacent to the Red Stick property.
D. Roadway Design/Plans
13. The ENGINEER shall modify the plans, as requested by the COUNTY, to provide a 4 -lane
roadway to 2 -lane roadway transition, at the project termini. This supplemental agreement
(Number 4) addresses the need to add back to the Hourly Rate Component, the $7,500.00
estimate, as approved in Supplemental Agreement No. 2. This was due to the funds being
utilized, as decided by the COUNTY, for evaluation of impacts on a realignment of SR -510,
east of US -1, to avoid further and specific property impacts.
14. The ENGINEER shall modify the plans, as requested by the COUNTY, to address
supplemental storm water design. The project storm water design and plans preparation was
advanced following the receipt of review comments from the COUNTY on the Pre -60%
Plans. The ENGINEER and the COUNTY agreed upon specific aspects of the work, such as
follows:
• The western project limits up to and including the Red Stick property. It was
approved that the location of Retention Pond 1, on the Gordon Property would be
developed, and stormwater run-off would also be collected east of 58`s Avenue and
would connect to the Red Stick existing pond system. Several alternatives were
presented and coordinated with the Red Stick owner. It is assumed that the Red
Stick property existing drainage system, and any permit modifications required for
the CR -510 project will be included with this supplemental agreement (Number 4).
The ENGINEER has evaluated the existing Red Stick permit, and several scenarios
to route and convey the project drainage. There are currently six (6) drainage
0
basins on the property, with outfall across the southeast portion of the property,
and eventually under the FEC Railroad, to a natural outfall system to the east. For
purposes of this proposal, the ENGINEER has assumed the least disruptive option
on the property, as for the golf course operation; however, the conveyance/routing
of the collected drainage may require resizing the pipe/conduit system to connect
to the southeastern property drainage basins system.
• The ENGINEER evaluated multiple alternatives of storm water management on the
Graves Brother's property.
• The ENGINEER also completed the storm water management system to the east of
US -1, to the eastern project limit, excepting out the Kennedy Property and
Retention Pond 5. The COUNTY has requested the ENGINEER to address storm
water management options for this property.
• The ENGINEER assumed the parameters, as set forth in the previous drainage
report, as prepared by LBFH for the MOT PD&E Study, and as provided by the
COUNTY.
Additional effort is required by the ENGINEER to: 1) re -do the eastern portion of the project
storm water management system due to the realignment of SR -510; 2) to adjust the specific and
certain roadway profiles, due to ground water intrusion at a much higher elevation; and 3)
supplement the current roadway design funds, that were utilized in determining multiple storm
water management options.
Additional effort is also required by the ENGINEER to re -do the plans, profiles, and cross-
sections, signalization plans at Bristol Bay access and signing and pavement marking plans for that
portion of roadway, SR -510, east of US -1, to the eastern project limit. The COUNTY has also
requested the ENGINEER to provide a right -turn deceleration lane into the Bristol Bay property,
for the potential frontage commercial portion of the property. The transition of the project travel
lanes through the intersection of US -1 will be accommodated in the centerline median. In
addition, the plateau geometry, intersections of all lane ridge lines, horizontally and vertically
(including super elevation transitions), will need to be addressed and adjusted accordingly to
mitigate this request. This area of the project was evaluated by the ENGINEER, and re-evaluated
for the right -turn deceleration lane and at the request of the COUNTY, to avoid the impacts to
specific properties.
G
M. Retention Pond Desien
The retention pond design for the project was considered with Supplemental Agreement No. 1.
This was an Hourly Rate Component for the project. At the time of the supplemental agreement, it
was assumed that the project may include up to five (5) drainage subareas, and possibly two (2)
areas where existing and/or proposed storm water management facilities could be utilized. The
designs on several of the facilities have been completed and need to be re -engineered due to
several factors: 1) realignment of SR -510, east of US -1; 2) preparation of several alternative sites
at the Graves Brothers, Kennedy and Red Stick properties; 3) evaluation of the storm water
management system north of SR -510 and east of 58`h Avenue, to provide alternatives to retention;
4) preparation of alternatives, on the Gordon property, to evaluate an additional retention facility
on the property, in lieu of proposing to pipe and fill the existing ditch in front of the Paladin
property for compensatory storm water storage; 5) preparation of alternatives on the Kennedy
property, which considered the size, and if additional storage could be sent to an already approved
permitted facility on the Bristol Bay development; 6) a revision to the Red Stick property permit
for accepting project drainage from CR -510 and 58th Avenue; 7) revisions to the approved CVS
site permit, based upon drainage routing modifications that will alter previous plans to include
retention facilities on the Graves Brothers property north of CR -510, and west of US -1; 8) an
overall project evaluation of ground water penetration, as the results of several hand augers have
provided information that differs from the preliminary drainage report, and is significantly
different in elevation; and 9) the appropriate level of calculations, as per the St. Johns Water
Management Control District, specifically, Chapter 11 of the handbook, to address a new
requirement for water quality on the removal of phosphorus from the project storm water
management system. This effort/fee will be contained under the Lump Sum Components of the
Roadway Design, in "Section V — Compensation."
N. Maintenance of Traffic (MOT,) Plans
Maintenance of Traffic plans will be required, to address several unique conditions of the project
that were not originally anticipated. The original project, and up to Supplemental Agreement No.
1, addressed the intersection improvements of CR-510/SR-510 and US -1, with the addition of the
approaches. After submission of the revised 30% plans, which included the revisions, the project
alignment went through multiple reviews. At the time, the MOT plans were to be prepared in a
generic fashion, and only to include typical section details, MOT notes for construction and
abbreviated plan sheets details for construction phasing.
The reviews from the alignment required multiple reverse curves and the raising of the US -1
intersection by approximately 5 -feet, which will require the preparation of more sophisticated
MOT plans, to address; 1) multiple stages; 2) evaluation of fill/embankment and temporary
0
structures; 3) temporary drainage measures; 4) minor, localized detours/temporary roadways, and
5) temporary traffic signal control for multiple phases of the US -1 intersection, and to comply with
FEC Railroad crossing requirements. The plans will be prepared at a reduced scale, 1 inch equal
to 80 feet and be stacked two (2) roadway segments per plan sheet. It is estimated that a total of
four (4) plan sheets will be prepared for "typical' MOT phasing/sequencing, both for advance
warning signing and for traffic control features that will address CR-510/SR-510, in the "typical'
areas of widening on either side of the US-1/SR-5 intersection. The intersection, and due to the
complexity of the embankment and the need for a temporary detour and temporary traffic
signalization, will require 1 inch equals 40 foot scale plans. This effort is estimated to include 16
plan sheets, and four (4) sheets for the temporary traffic signal plans. For the FEC Railroad
crossing, the ENGINEER estimates four (4) sheets, and four (4) additional sheets for
structural/embankment details, drainage requirements, signing and pavement markings, and
business Way Finding signs. The total estimated MOT plans set is equal to 32 sheets.
This effort/fee will be contained under the Lump Sum Components of the specific line item for
MOT Plans, in "Section V — Compensation."
O. Environmental Assessment/Regulatory Permitting Wetland Delineation
AS DIRECTED B Y INDIAN RIVER COUNTY, THE COUNTY WILL PROVIDE THE ENGINEER
WITH THE BELOW DESCRIBED SERVICES AS STIPULATED TO COMPLETE THIS PORTION
OF WORK FOR THE HEREIN DESCRIBED PROJECT.
1. Assessment/Regulatory Permitting
Wetland information is required to support the Project Development and Environmental study
previously prepared. The COUNTY will be required to conduct a wetland delineation of the
systems associated within the project limits and of the proposed retention pond sites. This effort
will include:
• Collection of existing or secondary data;
• A field review of established wetland boundaries, in accordance with the criteria set forth
in the Federal Manual for Identifying and Delineating Jurisdictional Wetlands;
• Preparation of a narrative, inclusive of the methodology, and graphical exhibits, denoting
the wetland sites and boundaries;
• And agency coordination and permitting to include Indian River County Planning
Division, St. Johns River Water Management District; and the US Army Corps of
Engineers.
F
It is assumed that endangered and threatened species surveys are not required for the project;
however, the COUNTY (Engineering staff) will coordinate with the Indian River County
Environmental office to obtain existing information on endangered and threatened species surveys.
This existing information will be included in the project environmental assessment report, to be
completed by the COUNTY.
2. Mitigation
Should the result of the above work effort require mitigation, the COUNTY will only advance that
work, should it be necessary. The mitigation effort may include: the need to perform a functional
analysis of the impacts, using the Uniform Mitigation Assessment Methodology, and the
preparation of specific data sheets for the US Army Corps of Engineers for each determined
wetland area of impact; the preparation of an Environmental Resource Permit Application; and
meeting with the US Army Corps of Engineers to resolve comments associated with the permit
application; and special attention and consideration will be given to avoid potential impacts to
wood stork core foraging areas.
P. Project Coordination/Administration
During the course of the project, the ENGINEER is required to coordinate with the COUNTY.
This coordination is in the form of correspondence, including electronic mail, telephone
conferences, meetings, documentation of meetings and responding to requests, on behalf of the
COUNTY. In the original and supplemental agreements to date, this particular effort was not
separated by any tasks. However, this Supplemental Agreement No. 4 will address this effort to be
included with the Roadway Design item.
This request is required due to several significant factors contributing to project delays that have
been no fault of the ENGINEER, or the COUNTY. The delays arose: from outside sources that
needed to supply plans; right-of-way information; and individual coordination with multiple
property owners. The coordination with property owners included correspondence, evaluating
requests from property owners' Engineers, meeting with property owners and providing specific
information to assist in the evaluation of project impacts.
In addition, the ENGINEER attended a meeting with FDOT to address the CR -510 and US -1
intersection. Also, additional information was gathered and collected to assist the COUNTY and
their Consultant in preparation of completing the Project Development and Environmental
document.
"SECTION IV - TIME FOR COMPLETION" is being modified to incorporate the following:
The time for completion of 90% design drawings and permit applications associated with the scope of
services detailed in this amendment (Number 4) will be four (4) months from the formal execution of this
amendment (Number 4). The adherence to this schedule is directly associated with, and impacted by
several individual property owners where drainage facilities are anticipated to be located. Should these
herein current project conditions be altered, the assumed time frame to complete the 90% plans will be
effected.
0J
"SECTION V — COMPENSATION" is being modified to incorporate the following:
