BACKGROUND DISCUSSION
Pegasus Engineering submitted a proposal on November 15, 2022, to provide final design and
permitting services for a new outfall system to be constructed along the east side of the
Wetland Park between 812 Wakulla Way and 312 Michael Blake Boulevard. An ICPR (Version 3)
model was developed for proposed conditions as part of preparing the 90% construction plans,
and the preliminary flood routing results indicate that constructing the new outfall system will
not ameliorate the flooding that presently occurs at the Michael Blake Boulevard and Wakulla
Way intersection.
·The joint-use stormwater pond that serves portions of Winter Springs Town Center,
Tuskawilla Road, and Winter Springs High School discharges into the Wetland Park near
the intersection of Tuskawilla Road and the Cross Seminole Trail through a 3’ x 6’ box
culvert connected to three (3) bubble-up structures. From this point, the discharge
continues east into the North Wetland Park which is topographically separated from the
larger South Wetland Park (refer to Figure 1).

·The ICPR model for proposed conditions was used to preliminarily investigate additional
drainage improvements to complement the new outfall system along Michael Blake
Boulevard. These additional drainage improvements are intended to intercept the flow
at the existing bubble-up structures and re-direct that discharge south along the Cross
Seminole Trail a distance of approximately 650 feet where a new outfall into the South
Wetland Park is proposed (refer to Figure 1).
·Modifying the existing outfall system crossing Tuskawilla Road to re-direct discharge
from the North Wetland Park to the South Wetland Park is consistent with the Winter
Springs Town Center Stormwater Master Plan Update1, including the hydration,
recharge and peak rate attenuation benefits that were permitted2 to occur within the
South Wetland Park.
·The preliminary flood routing results predicted by the ICPR model for proposed
conditions indicate that some type of system is required to property contain flood
stages within the Wetland Park and prevent adverse impacts to Michael Blake Boulevard
and Winter Springs Village Phases 1 and 2. Because a maximum containment height of
approximately 4-feet is needed, a sheet pile wall is anticipated in lieu of more cost
effective options like an earthern berm that would require a much more significant
encroachment within the Wetland Park.
·Construction impacts to the Cross Seminole Trail will be mitigated to the greatest extent
practicable by constructing the proposed drainage improvements within the vegetated
buffer along the west side of the South Wetland Park. Jurisdictional wetlands will be
delineated to ensure that the proposed drainage improvements are constructed entirely
within uplands, or alternatively the area of impact within jurisdictional wetlands will be
quantified for permitting purposes. Construction activities within the Wetland Park are
not anticipated to occur within conservation easements based on a review of the plats3
for the Wetland Park.

The ICPR model used to design and permit the proposed outfall and drainage improvements
includes the post-development discharge contribution from the Hickory Grove townhomes
project that is presently under construction. The final ICPR model for proposed conditions will
also be used to evaluate the hydraulic impact that the Hickory Grove townhomes project will
have on the proposed outfall and drainage improvements. Discharge rates for various storm
events will be predicted for the pre-development condition (i.e., the land use that existed
before the Hickory Grove townhomes project), which will be used to quantify the
development’s “pro rata share” of the post-development discharge rates conveyed by the
proposed drainage improvements. The results of this evaluation will be presented within a
Technical Memorandum that could potentially be used to develop a legal agreement between
the City and the developer for sharing the cost to construct the proposed outfall and drainage
improvements.

PROFESSIONAL ENGINEERING SERVICES
Pegasus Engineering, LLC (Consultant), shall provide the engineering services as itemized on the
Manhour and Fee Estimate provided as Exhibit “B”. It should be noted that this change order
includes only new task assignments, expanded task assignments and sub-consultant services
that are intended to supplement the previous authorization.
Referring to the information provided within Exhibit “C”, the scope of work for this change
order will require additional services from several sub-consultants as discussed below and as
illustrated on the following Figure 2.
Survey Sub-consultant .................................. Southeastern Surveying & Mapping Corp. (SSMC)
1.The topographic survey that was previously completed as part of the original
authorization will be extended a short distance north and a much greater distance south
to reach the intersection of Michael Blake Boulevard and the Cross Seminole Trail. The
additional topography will be used to define the limits of a sheet pile wall that is needed
to properly contain flood stages within the Wetland Park.
2.A new topographic survey is required along the west side of the Wetland Park where
discharge from the existing outfall crossing Tuskawilla Road will be intercepted and re-
directed south along the Cross Seminole Trail.
3.The survey scope of work will also include locating: existing utilities; geotechical soil
borings; pin flags placed in the field by the ecological sub-consultant; and specimen
trees that are 8-inches in measured diameter at breast height (DBH).
Geotechnical Sub-consultant ..................... Geotechnical and Environmental Consultants (GEC)
1.Although a $5,000.00 “geotechnical allowance” was included within the original
authorization, no geotechnical work has been performed to date. Therefore, the original
allowance will be replaced by a new scope of work for a geotechnical exploration with
soil borings to evaluate soil and groundwater conditions for the proposed outfall system
along Michael Blake Boulevard as well as the additional drainage improvements
proposed along the west side of the Wetland Park. The geotechnical engineering report
will also include structural engineering recommendations for designing the proposed
sheet pile wall to properly contain flood stages within the Wetland Park.

Ecological Sub-consultant .............................................. Breedlove, Dennis & Associates (BDA)
1.Although a $1,500.00 “wetland allowance” was included within the original
authorization, no ecological work has been performed to date. Therefore, the original
wetland allowance will be supplemented by a new scope of work for an ecological
assessment that includes field flagging the jurisdictional wetland line and investigating
the presence of threatened and endangered species for the outfall system proposed
along Michael Blake Boulevard as well as the additional drainage improvements
proposed along the west side of the Wetland Park. Because a SJRWMD permit is
required to authorize construction of the proposed outfall and drainage improvements,
ecological services will also encompass an Ecological Assessment Report (EAR), but will
not include permitting assistance (i.e., Task No. 3 of BDA’s proposal will not be
authorized). In the event that District staff issues a request for additional information
(RAI), the wetland allowance that was included within the original authorization will be
used unless the budgeted allowance is not sufficient for addressing the comments, and
another contract change order is required.
Structural Sub-consultant ............................................Florida Bridge and Transportation (FBT)
1.A sheet pile wall needed to contain flood stages within the Wetland Park will be
designed by a structural engineer based on recommendations presented within the
geotechnical engineering report.
BASIS OF PROPOSAL / ASSUMPTIONS
The conditions and assumptions contained within the scope of work for the original proposal are
also applicable to this change order proposal but will not be reiterated herein. The following
conditions and assumptions are noted as additional qualifications to this change order proposal.
1.This proposal does not include the following professional services. In the event that any of
these services are required in the future, it is assumed that an amendment will be
processed to encompass those additional services.
ü Stormwater modeling for existing conditions.
ü Permitting related to Section 404 of the Clean Water Act, including any applications
submitted to the U.S. Army Corps of Engineers (USACE) for “retained waters” or the
Department of Environmental Protection (DEP) for “assumed waters”.
ü Permitting with Seminole County related to the Cross Seminole Trail.

ü Modification or relocation of existing utility systems.
ü Legal sketches and descriptions for easement acquisition or vacating conservation
easements.
ü Maintenance of Traffic (MOT) operations and Traffic Control Plans (TCP).
ü Wetland mitigation.
ü Tree replacement and/or landscape plans.
ü Post-design services.
ü Construction Engineering and Inspection (CEI) services.
2.The original authorization included Subsurface Utility Engineering (SUE) based on a limiting
amount of four (4) utility test holes (soft digs) which should be sufficient to encompass all of
the proposed improvements.
3.Because the proposed construction activities are anticipated to result in more than 1-acre
of disturbed land, a National Pollutant Discharge Elimination System (NPDES) construction
permit application from the Environmental Protection Agency (EPA) will be required.
However, and although a Storm Water Pollution Prevention Plan (SWPPP), Notice of Intent
(NOI) and Notice of Termination (NOT) are applicable to this project, task assignments
related to NPDES permitting are not included in the scope of work for this proposal.
4.Permit application fees are not included and will be provided by others.
5.Construction plans will be prepared to scale on 24” x 36” sheet size. A single set of
construction plans will be prepared that is suitable for public bid and ready to award for
construction. All design parameters, surveys, and construction plans will be prepared and
submitted in English standard units. At this time, preparation of the construction plans is
anticipated to include the following sheets.

information you provided to us, as shown on Attachment 1, and our correspondence on July 31,
2023. The purpose of this investigation is to explore soil and groundwater conditions at the site
and to use the information obtained to provide geotechnical engineering recommendations for
site preparation, and design and construction of the outfall improvements. This proposal
presents our understanding of the project, our recommended scope of services, and a cost and
schedule for providing those services.
Site Location and Description
The site is located at the Wetland Park in Winter Springs, Florida as shown on Attachment 1.
More specifiaacally the site includes an approximate 800 foot portion of the Cross Seminole Trail,
south of the intersection with Tuskawilla Road and an approximately 1300-foot portion of
Michael Blake Boulevard north of the intersection with the Cross Seminole Trail. The general
vicinity of the property is characterized by single to multi-family residential and light commercial.
Vegetation along the trail and adjacent to Michael Blake Boulevard includes dense underbrush
beyond the maintained right-of-way.
Project Description
We understand that project plans for this site include the construction of an extension to the
existing bubble up structures to relocate the outfall further south and to install a sheet pile along

recommend the following scope of services:
• Stake boring locations at the site.
• Clear utilities at the boring locations.
• Mobilize Mini Track drilling equipment and personnel.
• Perform 7 Standard Penetration Test (SPT) borings to a depth of 25 feet along the
proposed alignment of the sheet pile wall.
• Perform 4 Standard Penetration Test (SPT) borings to a depth of 10 feet along the
proposed additional drainage improvements alignment.
• Perform routine laboratory soil classification tests to enhance visual soil classification of
samples obtained.
• Issue a geotechnical engineering report signed and sealed by a Geotechnical Engineer
licensed in Florida that will address the following topics:
o Subsurface conditions at the boring locations
o Measured and estimated seasonal high groundwater depths
o Site preparation
o Fill selection, placement and compaction
o Foundation design recommendations
o Constructions recommendation, including soil parameters and global stability
analysis for the sheet pile wall.
Cost
The cost to provide the scope of services is a LUMP SUM fee of $19,995.00. This fee includes an
electronic copy of our report emailed to you.
Schedule
Our schedule to complete the work will be about 8 weeks from your written notice to proceed.
If requested, verbal recommendations can be provided after the field work is completed. Our
schedule is highly dependent on Sunshine 811 and the utility providers/locators clearing the soil
boring locations within the allotted 48 hour time frame.

RE: Structural Design and Plan Sheet for Sheet Pile Wall
Wetland Park Outfall, City of Winter Springs
Proposal for Structural Design Services
FBT Project Number 23-58.01
Dear Greg:
Florida Bridge and Transportation, Inc. (FBT) is pleased to submit this proposal to PEGASUS
for engineering services for the above referenced project. The scope of design services for this
work order includes the following:
1) Design and Plan Production: FBT will provide the structural design and plan sheets for
the proposed sheet pile walls per the concept shown in the plan provided by Pegasus. It is
assumed the sheet pile walls will be cantilever walls (not braced or anchored). FBT will
provide design and details for the sheet pile and the concrete coping with railing. The
railing will be a standard railing from FDOT Standard Indexes and no custom
modifications are included. It is assumed the exposed portions of the sheet pile will be
coated with standard coal tar epoxy (black), and special coating systems and colors will
not be required. Wall control drawings will not be provided (wall geometry will be
shown in Pegasus’ plans). The plans and calculations will include one custom design with
details for the “short sheets” which will be required to span across an obstruction such as
a utility or other buried element.
2) Meetings, Specifications and Cost Estimates: FBT will attend one status meeting (if
required) with the City staff and Pegasus. The project specifications will consist of the
FDOT Standard Specifications for Road and Bridge Construction, and supplemental
specifications are not anticipated or included. FBT will provide one estimate of probable
construction cost for the structural items. FBT will assist Pegasus develop a bid schedule
for the structural items.
3) The project deliverables will consist of 100% and signed and sealed “final” plans and
structural calculations. We understand the final deliverables may include 24x36 sheets.
The reprographic cost for FBT’s portion of the project is included in the fee below.
We propose a total lump sum fee of $13,500.00 for all FBT's basic structural engineering
services indicated above. The work will be invoiced monthly on a percent complete basis. If the
work is stopped by PEGASUS or others for any reason before completion, FBT will be
reimbursed for the hours expended up to that point at an average hourly rate of $150 per hour.
