TO
CONSULTING ENGINEERING SERVICES AGREEMENT
FOR
COLLIER BOULEVARD (C.R. 951) SOUTH EXTENSION
(Davis Boulevard to Main Golden Gate Canal)
PROJECT NO. 60001
October 6, 2010
The CONSULTANT has been requested and retained to provide additional engineering
services associated with final design and completion of construction of the Collier
Boulevard South Extension Project (Davis Boulevard to Main Golden Gate Canal). These
additional services are based on various design revisions and scope of work additions
requested by the Collier County Growth Management Division Transportation
Engineering Department to address the changing needs and conditions along the project
corridor and to conform to adjacent development agreements. In addition, some of the
additional services are required to match "As- Built" conditions of surrounding projects
and resolve surrounding property issues. These services are necessary to resolve project
stakeholder issues (Collier County Transportation Department, Collier County Solid
Waste Department, Collier County Utility Department, FDOT, FHWA, SFWMD -BCB,
Abercia Development, City Gate Development), and finalize the project permitting and
design.
Change Order No. 4 provides for the CONSULTANT'S services to be modified to add
the following Design scope of services to Collier County Project No. 60001. The
following CONSULTANT Services are an addition to the original contract:
8. FDOT Design and Permitting Requirements: The following tasks are required as a
result of FDOT comments made and requirements stated during the FDOT review of
the Collier Boulevard Project Plans. The Additional Services that are required and
will be provided by the Engineer to obtain approvals and permits included the
following:
a. Typical Section Revisions and Complete Project Plans Redesign - Post
60% Plans due to FDOT Comment and Approvals - $198,254.49
16A 8
Attachment A
Change Order No. 4
Collier Boulevard (SRICR 951)
Davis Blvd (SR 84) to Main Golden Gate Canal.
Project No. 60001
Prior to 30% submittal, a coordination meeting with FDOT District 1
District Interstate Review Committee (DIRC) was held in Bartow to
review the proposed design for this project. As part of the discussion
at this meeting, the design exceptions for vertical clearance and
longitudinal grade along the curb and gutter were addressed. Initial
comment from the FDOT indicated that although a design variance
would need to be submitted for both, due to the excessive cost of
revising the existing condition, approval would be recommended.
Design Variance 1 dealt with the fact that the existing vertical
clearance under the 1 -75 Bridge is currently substandard (16' -3" vs.
16' -6 ") and the proposed clearance would be at 16' -1 ". Variances for
vertical clearances under I -75 were previously granted by FDOT to
Collier County for other projects, so based on the excessive costs to
remedy the situation, approval for this project should not have been
delayed or denied especially since resulting clearance was greater
than the 16' -0" minimum.
• However, based on discussions with FDOT after submittal of the
design variation, the potential for approval of the design variances
did not appear to be forthcoming.
• After discussions with TECM it was agreed that CH2M HILL should
redesign the plans to lower the profile at the I -75 Bridge to provide
16' -5" of under - clearance in order to obtain FDOT concurrence with
the design in a timely manner and preserve the project schedule.
• Design Variance 2 was to due to the fact that the existing profile of
roadway, would not provide the required minimum longitudinal
grade when the typical section was modified from a rural section to
an urban section. Curb and gutter was considered in the initial design
for consistency since exclusion in this project would have resulted in a
0.75 mile gap in the curb through the 14 mile corridor. In addition, it
contained the drainage runoff and provided a means for raised
sidewalk along the corridor.
• To modify the longitudinal slope in areas that did not meet standards
would require completely re- profiling the roadway during
construction at a cost in excess of $23M ( >10% of the overall estimated
project construction cost).
• However, based on discussions with FDOT after submittal of the
design variation, the potential for approval of the design variances
did not appear to be forthcoming.
• After discussions with TECM Design, it was decided that
CH2M HILL should revise the roadway typical section from urban to
16A 8
Attachment A
Change Order No. 4
Collier Boulevard (SR/CR 951)
Davis Blvd (SR 84) to Main Golden Gate Canal
Project No. 60001
suburban and to redesign the plans in order to obtain FDOT
concurrence with the design in a timely manner and preserve the
project schedule.
• The change in typical section from urban to suburban will require
CH2M HILL to modify the Drainage Design along Collier Boulevard
and to revise and expand tl�e Basins to accommodate the revised
roadway design. Drainage areas will change, drainage modeling will
change, calculations will change and Permits will need to be revised.
The project's original scope of work and 60 % Design assumed that
due to the excessive costs of making the required modifications to the
existing condition, the FDOT would approve the Design Variances
requested since similar variances were approved on previous projects.
Also during the initial coordination meeting with the FDOT, they
indicated that approval would not be an issue. CH2M HILL
proceeded with design based on that understanding. Therefore this
task is considered Additional Services
• Services required to finalize the plans, specifications and estimates
include: Numerous Conceptual Design AIternatives, Complete
Roadway Re- Design - Post 60% Plans (Typical Section Package,
Typical Sections, Plan and Profile, Cross Sections, Signing and
Marking, MOT, Utility Plans, Quantities); Drainage Design; Drainage
Calculations, and Abercia Development and Collier Boulevard Permit
modifications.
b. Preparation of a FDOT Interchange Analysis and Operations Report
(IAOR) and Methodology Letter of Understanding (MLOU) - $23,735.54
At the coordination meeting with FDOT and FHWA at the 30%
design submittal, FDOT indicated that a MLOU and IAOR would
need to be prepared and approved by both FDOT and FHWA. This
would be required to ensure that the planned improvements in the
FDOT Limited Access ROW would conform to the existing
configuration of the interchange as well as the FDOT "future"
planned improvements to the interchange. The FDOT wanted the
County's Consultant to prepare both documents. The County agreed
to have CH2M HILL prepare the documents.
• The project's original scope of work could not have anticipated this
FDOT request for services and thus did not include the above tasks.
Therefore this task is considered Additional Services
• Services required to finalize and obtain the FDOT Permit include:
Meetings, Data Gathering, Coordination with FDOT Consultants
working on Interchange Planning Tasks, Interchange Performance

c. Additional FDOT Permitting Requirements (Permits) - $31,858.31
The design and permitting of the Collier Boulevard Project requires
extensive effort with respect to coordination with FDOT and FHWA.
For Approval, the FDOT has required that, in addition to the
Drainage Connection Permit required for discharging stormwater into
the FDOT ROW, CH2M HILL will be required to submit the
following three (3) separate Permits:
o Driveway Connection Permit with Plans
o Utilities Permit with Plans
o Signalization /Signing and Marking/ Lighting Permit with
Plans
The project's original scope.of work did not anticipate having to
prepare and submit three (3) additional (Drainage Connection Permit
was assumed) Permits for the above mentioned portions of work.
Based on previous experience working on projects within FDOT
ROW, it was assumed that copies of the applicable plans would be
submitted to FDOT for their files upon completion of design.
Therefore this task is considered Additional Services
• Services required to finalize and obtain the FDOT Permits include
Coordination, Meetings, Project Plan Changes, and Preparation of
three (3) Additional Permit Packages.
9. Match to "As- Built" Conditions of Existing and Concurrent Projects: The project
plans are developed on information available at the start of the design process. Due
to continued growth and development, many site conditions on surrounding County
FDOT and /or developer projects change during the design period which requires
redesign efforts. These changes generally require additional coordination, design
survey, design analysis and revisions to the construction plan documents. Additional
Services that are required and will be provided by the Engineer include the following:
a. Conceptual Alternatives and Revisions to NW Corner of Beck/Collier
Intersection - $33,306.56
a Due to ROW Acquisition concerns from the adjacent property owner,
Collier County requested that CH2M HILL prepare various
alternatives for the NW corner of the Davis Boulevard - Collier

Collier Boulevard (SrVCR 95I)
Davis Blvd (SR 84) to Main Golden Gate Canal
Project No. 60001
Boulevard Intersection and evaluate the ROW requirements of each
alternative.
• Numerous concepts will be prepared and from them, three (3) Dual
Right Turn Lanes alternatives will be designed using various size
design vehicles (WB -50, WB -62 etc.). The ROW impacts of each of the
alternatives will be evaluated.
• The alternatives will also need to consider the FDOT - Davis
Boulevard Widening Project (being designed by TY Lin) to evaluate
and provide sufficient ROW for the Intersection Signalization.
• The changes being made by TY -Lin to this intersection and how it will
be constructed require numerous changes to the plans to account for
design changes, signal location changes and maintenance of traffic
(MOT) phasing revisions.
• The project's original scope of work could not have anticipated the
property owner contesting the minimal ROW Acquisition at the
corner and the late changes to the TY Lin Roadway, Signal and
Maintenance of Traffic (2 times) Design and thus did not include the
above tasks. Therefore this task is considered Additional Services
• Services required to finalize the plans, specifications and estimates
include: Site visits, Conceptual Alternatives (3); Roadway Design
revisions (Plan and Profile); Drainage Design revisions, Sketch and
Descriptions and ROW Map Revisions; Coordination with TY Lin,
Signal Plan Review MOT Plan revisions.
b. Utility Drive/Magnolia Pond Drive Intersection Improvements -
$22,716.23
The original scope of work was revised during 60% Design to design
the Utility Drive /Magnolia Pond Drive Intersection as a Signalized
Intersection with Collier Boulevard as opposed to directional lefts.
Collier County Planning requested this due to the County being
delayed in securing an agreement with an adjacent developer (City
Gate) for a portion of White Boulevard (private road) to be transferred
to the County. In addition, changes associated with the delayed
construction of Noah's Way by the Abercia Developer also
contributed to the need for a Signal Design and intersection revisions
at the Utility Drive/ Magnolia Pond Drive Intersection. Multiple
concepts for lane configurations on Collier Blvd, as well as on Utility
Dr. were developed.
• After discussions with TECM Designs, Planning and Traffic, it was
determined that this would be included in the project bid plans as a
16A 8

Change Order No. 4
Collier Boulevard (SR/CR 951)
Davis Blvd (SR 84) to Main Golden Gate Canal
Project No. 60001
signalized intersection with Collier Boulevard with minimum Iane
assigrunents to economically accommodate the interim condition of
having a signal (temporary) at this intersection as opposed to where
the permanent "future" Signal will be at the City Gate Drive / NoaWs
Way Intersection.
• The medians of Collier Boulevard will be designed to accommodate
the signalized intersection in the interim condition while providing
for the future reconfiguration of the intersections to Collier Boulevard
directional lefts with minimum throw away costs.
• The project's original scope of work could not have anticipated the
various alternatives and conditions that needed to be prepared and
accommodated due to the changing developer agreements and plans
(caused mostly be economic conditions). Thus the scope did not
include the above tasks. Therefore, this task is considered Additional
Services
• Services required to finalize the plans, specifications and estimates
include preparation of multiple Conceptual Design Alternatives and
evaluation of traffic operations. Once an alternative is approved:
Roadway Design (Typical Section, Plan and Profile, Cross Sections,
Signing and Marking, Signalization, Quantities).
c. Design Changes resulting from Abercia Development - $37,386.89
The Abercia Development Agreement with the County has had a major
impact on the design of the Collier Boulevard project due to site
development changes, changes to Magnolia Pond Drive and Noah's Way
typical section, alignment and lane configurations, as well as the fact that a
significant portion of the Nest side ROW and Drainage Treatment and
Attenuation requirements of this project are directly tied to the Abercia
development There were many changes to the agreement including
postponement of development construction which occurred late in design
(post 60% Phase) that will require significant design changes. These items
include:
Drainage conveyance system redesign for implementation of a Joint
Use Pond with the Abercia development. The original design that was
agreed to by the Abercia Developer and Collier County showed the
Collier Boulevard Drainage System tying into their parking area catch
basins. This stormwater would then be transferred to the pond via
their internal conveyance system. Due to internal site conveyance
constraints, the Developer requested that the County install their own
>2,400 LF "trunk line" pipe to convey the stormwater to the agreed to
joint Use Pond. The County agreed to this modification and CH2M
Attachment A
Change Order No. 4
Collier Boulevard (SR/CR 95 1)
Davis Blvd (SR 84) to Main Golden Gate Canal
Project No. 60001
HILL will be required to redesign the onsite drainage system and
conveyance.
• Modifications to the Magnolia Pond Drive and Noah's Way
Intersections will be required due to Abercia Site Plan shifting
locations in the coordinate system. CH2M HILL. noted the error in the
Abercia Site Plan and both Developer and CH2M HILL will be
required to modify their design plans.
• County Planning Department requested that CH2M HILL prepare
conceptual design alternatives (a 3 -lane and 4 -lane roadway) to
realign Magnolia Pond Drive to accommodate initial roadway /site
planning as well as future roadway/ site planning to minimize
unnecessary initial costs and future throw -away costs when the
signalized 'intersection was eventually moved to the City Gate
North/ Noah's Way Intersection.
• Preparation of documentation of drainage calculations for inclusion
into the Abercia Permit submittal to SFWMD and revisions to Collier
Blvd Permit due to the changed Abercia Permit submittal.
• Revisions to the pathway and berm treatment between Magnolia
Pond Drive and Noah's Way to accommodate the Abercia
Developer's request in order to maximize their site parking without a
re- design on their part which could have affected their existing
agreement with their commercial client.
• Preparation of Conceptual Conveyance System, Treatment Pond
Design, Main Golden Gate Canal Ditch Improvements for Meetings
and Coordination with SFWMD.
• Preparation of "initial" conveyance system and pond design due to
the Abercia Developer postponing construction of the development,
requiring Collier County to include construction of the Abercia pond
and outfall in their project.
• The project's original scope of work could not have anticipated the
requested design changes nor changes to the Abercia Development
Agreement with Collier County and thus did not include the above
tasks. Therefore this task is considered Additional Services.
Please Note: All changes requested and made benefitted Collier
County as part of the Abercia Developer Agreement.
• Services required to finalize the plans, specifications and estimates
include preparation of Conceptual Design Alternatives for Magnolia
Pond Drive; Noah's Way, Roadway Design (Typical Section, Plan and
Profile, Cross Sections, Signing and Marking, Quantities); Significant

and Map revisions.
d. City Gate Blvd. N/Noah's Way Intersection Improvements - $19,826.66
The original scope of work was revised during 60% Design to design
the City Gate Blvd. North /Noah's Way Intersection as a Directional
Left Intersection with Collier Boulevard as opposed to a signalized
intersection. Collier Comity Planruing requested this due to the
County being delayed in securing an agreement with an adjacent
developer (City Gate) for a portion of White Boulevard (private road)
to be transferred to the County. In addition, changes associated with
the delayed construction. of Noah's Way by the Abercia Developer
also contributed to the need for directional Iefts from Collier
Boulevard NB and SB. Multiple concepts for lane configurations on
City Gate Boulevard North and Noah's Way were developed.
After discussions with TECM Design, Planning and Traffic, it was
determined that this would be included in the project bid plans as a
directional left intersection with Collier Boulevard with maximum
typical sections built (but initially striped out) to economically
accommodate the interim condition of having directional lefts
(temporary) at this intersection as opposed to the permanent "future"
Signal.
The medians of Collier Boulevard will be designed for initial
directional lefts that would accommodate a signalized intersection
when it is reconfigured in the future with minimum throw away
costs. The foundations for the future signalized 'intersections will be
designed and located to avoid construction issues and utility conflicts
in the future when the signal foundations and poles are installed.
The project's original scope of work could not have anticipated the
various alternatives and conditions that will need to be prepared and
accommodated due to the changing developer agreements and plans
(caused mostly be economic conditions). Thus the scope did not
include the above tasks. Therefore, this task is considered Additional
Services.
• Services required to finalize the plans, specifications and estimates
include preparation of multiple Conceptual Design Alternatives and
evaluation of traffic operations. Once an alternative is approved:

e. Evaluation of Existing 48" Water Main under I -75 - $5,993.56
• The proposed widening design of Collier Boulevard under the 1 -75
structure will result in a portion of the existing 48" Water Main being
located under the proposed left turn lane from Collier Blvd SB to I -75
SB. SUE was performed to verify the depth of the line.
Upon investigation of the existing utility it was found that the depth
of the 48" water main along Collier Blvd SB under the I -75 Bridge was
shallower than shown on the As -Built plans obtained at the County
Utilities offices. Instead of 48" of cover shown on the As- Built plans,
there was only 36" of cover (per SUE Investigation) in some locations.
This meant that the proposed widening would result in a 100 ft
section of the pipe having a minimum depth of cover of less than 36 ".
• After meetings with Collier County staff, a revised design (Design
Change No. 1) was prepared which showed that the 48" pipe could
remain in place with 100' of the pipe located under the left turn lane
from Collier Blvd SB to I -75 SB. This 100 ft section of pipe had a
minimum depth of cover of 34.5" to 36 ". County PUED initially
agreed to the solution and it was presented to the FDOT.
As a stipulation of their approval, the FDOT required profile and
cross slope changes to the concept (Design Change No. 2) to
eliminate the existing low point from between the 1 -75 NB and SB
structures.
• The redesign was completed and approved by FDOT, however,
Collier County PUED indicated that the cover and location of the 100'
of pipe was not acceptable and would require it to be relocated.
Due to the excessive cost of relocating the existing 48" Waterline, the
FDOT agreed to a reduction of the proposed length of turn lane (so
the existing 48" Water main would not be under the turn lane and
also agreed to accept a design variance for the Collier Blvd SB
roadway. This required a third redesign of the roadway under 1 -75
(Design Change No. 3).
The project's original scope of work could not have anticipated the
issues associated with extending the left turn lane and the resulting
sub - standard cover on the existing 48" Water main since no utility
investigations were done before the scope was developed and thus
did not include the above tasks. Therefore, this task is considered

10. Collier County Requested Improvements for Future Development: Due to
continued growth and development, many site conditions on surrounding County
FDOT and /or developer projects change during the design period which requires
redesign efforts. This is required in order to make the projects compatible and avoid
future throw -away construction by incorporating the changes at a later date. These
changes generally require additional coordination, design survey, design analysis and
revisions to the construction plan documents. Additional Services that are required
and will be provided by the Engineer include the following:
a. Beck Blvd Realignment and Addition of Right Turn Lane - $30,440.33
Based on the ROW restrictions of Davis Boulevard, the Davis
Boulevard lane geometry was revised by the FDOT Consultant TY Lin
to remain within the existing ROW and an eastbound free -flow
"ramp" was designed behind the commercial corner parcel. As a
result, Collier County requested that the alignment of Beck Boulevard
be redesigned to better align with the revised configuration of Davis
Boulevard.
• Collier County Planning also requested that a separate right turn lane
for Beck Boulevard be designed at this time to accommodate the
future traffic demands of Beck Boulevard.
• This additional right turn lane will require access management
changes, a retaining wall to reduce right of way impacts to the
adjacent commercial development, and the requirement far
acquisition of 2 new ROW parcels. Inclusion of these changes with
this project would reduce "throw away" costs and eliminate impacts
to the Collier -Beck intersection in the future.
+ The project's original scope of work could not have anticipated the
late changes to Davis Boulevard due to ROW issues faced by the
FDOT and the modifications to Beck Boulevard requested by Collier
County Planning to accommodate the future needs of Beck
Boulevard. Therefore, this task is considered Additional Services
+ Services required to finalize the plans, specifications and estimates
include Roadway Design (Typical Section, Plan and Profile, Cross
Sections, Signing and Marking, Quantifies); Retaining Wall Design;

revisions.
b. Future Beck Boulevard Extension Drainage Revisions - $9,616.98
• During design of the Phase II Plans (60 %) CH2M HILL was requested
by Collier County Planning to revise the size of the drainage trunk
line and proposed dry detention area to provide additional capacity
in the storm water drainage system to accommodate the future
expansion of Beck Boulevard to the east.
• These revisions would eliminate the need in the future to modify the
drainage conveyance system.
• The project's original scope of work could not have anticipated the
request made by Collier County to accommodate the future needs of
Beck Boulevard. Therefore, this task is considered Additional
Services
• Services required to finalize the plans, specifications, estimates and
permits include Drainage Design, Dry Pond revisions and Permit
modifications.
11. Resolve Surrounding Property Issues: During construction, issues arise due to
stakeholder concerns that need to be addressed in a timely manner to expedite
design and construction and /or convey a positive public image associated with the
project. Concerns and requests from adjacent property owners are received and
reviewed by County and project staff for resolution. Additional Services that are
required and will be provided by the Engineer include the following.
a. Addressing Eminent Domain Issues with Property Owner - $21,373.31
• During Design of the FDOT Davis Boulevard Project and Collier
County Collier Boulevard Project, an adjacent property owner on the
northwest corner of Collier Boulevard and Davis Boulevard contested
the minimal ROW Acquisition (corner clip) of their property. The
County requested that CH2M HILL review ROW needs, prepare
exhibits, develop alternative concepts, and generate plans for
geometry, signing and marking, drainage and signalization that
clarifies the need for the minimum ROW acquisition. The service to be
provided by CH2M HILL include:
• Meeting Attendance with County and FDOT
• Multiple Concept(s) evaluation

• Three (3) Deposition Meetings with lawyers.
• Preparation and Attendance at two (2) Court Hearings
• Changes to Design Plans to address judge concerns
• Reviews with FDOT to review revised signing plans and turn
lane geometry
• The project's original scope of work could not have anticipated the
property owner contesting the minimal ROW Acquisition at the
corner and the request of Collier County to assist them with
defending the Eminent Domain case. Therefore this task is considered
Additional Services
Services required to address eminent domain issues and finalize the
plans, specifications and estimates include Field Reviews, Meetings
with County and FDOT, Evaluation of Site Plans and Geometric
Design Alternatives, Preparation for and Attendance at Depositions,
Preparation and Attendance at Court Hearings, Changes to Design

12. SFWMD Additional Permitting Requirements: During the Permitting Phase of the
project, the SFWMD requested that the project survey limits be extended to include
the entire FDOT Interchange infield area as well as the outfall ditches up to the box
culvert crossing locations. Additional Services that are required and will be provided
by the Engineer include the following:
a. Additional Survey Required for Extension of Project Drainage
Limits - $28,322.64
• As part of the Original Scope, the anticipated survey boundary was
limited to the extent of the proposed physical construction
improvements utilizing the existing FDOT drainage facilities.
• As a result of our initial design work, it became apparent that the field
conditions along I -75 within FDOT ROW had been modified over the
years and the FDOT ditch facilities were changed from their original
concept.
In addition, SFWMD is requiring preparation and submittal of a
signed and sealed topographic survey for the limits of permitted area
up to and including all existing and proposed outfall locations. It has
become necessary to extend the limits of the initial survey to include
the limits of the existing FDOT drainage to the potential outfall,
which is located approximately 4000 feet from the Project area, to

verify flow direction and set the modified pre - design conditions for
this project.
• This is required to provide CH HILL enough information to
complete design to SFWMD and FDOT requirements so they would
review and approve the Permits.
The project's original scope of work could not have anticipated and
did not include all the survey that was being required. by SFWMD
and FDOT. It would have been unrealistic to foresee that the SFWMD
would insert the requirement for a full topographic survey to the
outfalls during the initial project scoping. Therefore this task is
considered Additional Services
Services required to gather survey data, finalize the plans,
specifications and estimates and obtain SFWMD Permits include site
visits; extensive field topography survey; coordination and
incorporation of new survey data into the original project terrain
model. Drainage Design changes, drainage calculations and Permit
modifications.
b. SFWMD Dewatering Permit - $9,994.91
During the Permitting Phase of the Design Contract, Collier County
requested that CH2M HILL prepare a Dewatering Permit for the
Project. Typically this is a requirement of the construction contractor,
but the County requested that due to the SFWMD changing permit
requirements, CH2M HILL prepare the permit to expedite the
process. CH2M HILL will prepare a Dewatering Permit -,vhich will be
submitted with the Collier Boulevard ERP (Permit) for the project.
This Permit will be available for the Contractor to use (or modify)
when the project goes to construction.
® The project's original scope of work could not have anticipated these
services which were requested by Collier County during the
Permitting Phase. This decision was made to help the Contractor
during construction and avoid potential project construction delays.
Therefore this task is considered Additional Services
o Services to prepare and obtain the permit include Dewatering Plans
Preparation; Drainage Calculations and Preparation of Dewatering
Permit.
13. Utility Design and Relocation Services: During the scoping of the design of this
project, it was agreed to by Collier County and CH210 HILL to exclude certain design

elements due to the uncertainty of what would be required. It was agreed that the
Utility Design and Relocation Services would be added to the contract once the
actual footprint of the project was determined and impacts to existing utilities could
be evaluated. Only utility coordination, research and minimal SUE services were
included in the initial scope. The Additional Services that are required and will be
provided by the Engineer include the following.
a. Utility Design and Relocation - $160,001.30
Once the project typical section, geometry and drainage facility
design was agreed to and conceptually approved by the County,
FDOT and SFWMD, the actual impacts to the existing facilities were
determined. To construct the project in a limited ROW with existing
and planned development adjacent to both sides of the roadway,
relocation and /or modification of the following utilities will be
required:
