EVALUATION OF MAJOR DESIGN CHANGES AND REVISED DESIGN
CRITERIA (e.g., Typical Section Changes, Alignment Shifts, Right of Way Changes,
Bridge to Box Culvert, Drainage Requirements, revised design standards).
The approved 1998 SEIR addressed the impacts associated with the proposed
Suncoast Parkway 2 from US 98 to US 19 through Citrus and Hernando Counties,
Florida. The proposed mainline consisted of four 12-foot wide mainline lanes, two in
each direction, separated by a 64-foot median. The facility is a new alignment in a
northerly direction through Hernando and Citrus Counties and connects the existing
Suncoast Parkway 2 with US 19 north of Crystal River, Florida.
This reevaluation is being conducted to evaluate design changes that have occurred
since the SEIR was approved on February 6, 1998. These changes are summarized in
the following bullets and discussed in detail below.

attachments.
A. Alignment Modifications
The project includes three alignment revisions within the 26-mile corridor. The first
alignment revision runs from south of the US 98 interchange to north of the US 98
interchange. The approved 1998 SEIR alignment was located further to the east and
resulted in isolating a portion of land that is now part of the Annutteliga Hammock tract
purchased by the State of Florida. To minimize the impacts to the protected lands, the
alignment has been moved west, closer to the existing Progress Energy right-of-way,
Progress Energy easement, and the Florida Gas Transmission easement. This
minimizes the impacts to the conservation lands and will be addressed in the update to
the existing Memorandum of Understanding with the Florida Department of
Environmental Protection. Figure V.A.1 illustrates the general alignment revision.
The second alignment revision is through the Lecanto Sandhills area. The approved
1998 SEIR alignment included a mainline toll plaza in this area. The land was
subsequently purchased by the Florida Department of Environmental Protection (FDEP)
as conservation land with the full knowledge that the Suncoast Parkway 2 could
potentially impact a portion of the site. Citrus County also sent letters to FDEP and the
Governor stating they only supported this acquisition if Suncoast Parkway 2 was
allowed to traverse the site. The toll plaza has been removed from this portion of the
alignment and the alignment has been relocated to the west to run parallel and

immediately adjacent to the existing Progress Energy right-of-way. As with the
alignment through the Annuttilega Hammock tract, this minimizes the impacts to
this conservation area. Figure V.A.2 illustrates the general alignment revision.
The third alignment revision is from south of the SR 44 interchange to north of
the SR 44 interchange. Heavy traffic from westbound SR 44 southbound
Suncoast Parkway 2 requires a reconfiguration of the interchange. This
reconfiguration relocates the southbound on-ramp in the southwest quadrant of
the interchange at Crystal Oaks Drive to a loop ramp adjacent to the southbound
off-ramp in the northwest quadrant, reducing impacts to the Crystal Oaks
neighborhood. The realignment of the Suncoast Parkway 2 mainline north of SR
44 eliminates the realignment of North Maylen Road and associated impacts to
the properties east of North Maylen Road. Figure V.A.3 illustrates the general
alignment revision.
B. Typical Sections
The approved 1998 SEIR provided a four-lane Suncoast Parkway 2 with two 12foot lanes in each direction separated by a 64-foot median within a 400-foot rightof-way. The typical section has been modified to provide the same four-lane
mainline with the median modified to 88 feet. The right-of-way for the proposed
improvement remains 400 feet; however, it is modified to provide 350 feet of
limited access right-of-way for Suncoast Parkway 2 (typically centered in the
right-of-way) and 50 feet of right-of-way for a multi-use trail. The multi-use trail is
a continuation of the multi-use trail provided on Suncoast Parkway 1 south of US
98 and provides potential connections to proposed local and state trails.
Figure V.B.1 illustrates the proposed mainline typical section.

C. Design Criteria
Table V.C.1 lists the design criteria from the Preliminary Engineering Report
submitted as part of the approved 1998 SEIR. Table V.C.2 lists the current
design criteria used in the design of Suncoast 2. These differences are due to
changes in FDOT’s design criteria from 1998 to 2009.

D. Interchanges
The approved 1998 SEIR provided interchanges at US 98, Cardinal Street, SR 44, CR
495 and the termini at US 19. The interchange locations and the proposed staging of
the interchanges remain the same (the interchanges at US 98, SR 44 and US 19 are
part of the initial construction and the interchanges at Cardinal Street and CR 495 are to
be constructed when the travel demand warrants the additional access). The
interchange configurations at Cardinal Street and SR 44 are modified as described
below.
The approved 1998 SEIR had a diamond interchange at Cardinal Street with Suncoast
Parkway 2 overpassing Cardinal Street. The Cardinal Street interchange is proposed to
remain as a diamond interchange with Cardinal Street overpassing the Suncoast
Parkway 2. The existing topography in the area generally rises from south to north. By
lowering the profile of Suncoast Parkway 2 below the existing grade, Cardinal Street
can overpass the Suncoast Parkway. This significantly reduces the cost of the facility
as less embankment material is required. In addition, the view shed along Cardinal
Street will not be interrupted by the Suncoast Parkway. The revised Cardinal Street
interchange concept can be seen on the Preliminary Concept Plans, included as
Attachment 2 to this document.
The modifications at the interchange with SR 44 were developed to provide improved
traffic operations at this interchange. Updated traffic projections indicate that the
westbound SR 44 to southbound Suncoast Parkway 2 movement is projected to be
substantially higher than the projections developed for the approved 1998 SEIR. This
increase is due to the revisions in the future land use plan for the area. To
accommodate the increased traffic volume, the direct diamond ramp for eastbound and
westbound SR 44 to southbound Suncoast Parkway 2 has been revised to be a loop
ramp located in the northwest quadrant of the interchange. This configuration allows
the westbound SR 44 to southbound Suncoast Parkway 2 traffic to make a right-turn
rather than a left-turn, significantly improving traffic operations. The right-of-way
required for the proposed interchange is approximately the same as the previous
interchange; however, it involves different properties. The revised SR 44 interchange
concept can be seen on Figure V.A.3 and the Preliminary Concept Plans, included as
Attachment 2 to this document.
E. Right-of-way Requirements
The approved 1998 SEIR identified approximately 1,500 acres of right-of-way for the
improvements. The 1998 Preliminary Engineering Report prepared in concert with the
approved 1998 SEIR identified 1,797.1 acres of right-of-way required for the
improvements. With the proposed alignment and interchange configuration revisions,
the right-of-way requirements for Suncoast Parkway 2 are currently 1,754 acres. The
acreage includes the right-of-way required for the roadway (mainline Suncoast Parkway
2, interchange ramps and cross street improvements), stormwater management areas,
access roadways and the multi-use trail.
12
F. Access Road Requirements
The approved 1998 SEIR included a series of local frontage or access roadways to
provide access to adjacent parcels that were impacted by the implementation of
Suncoast Parkway 2. With the modification to the roadway alignment and interchange
modifications, some revisions to the frontage/access roads are necessary. Table V.F.1
lists the differences between the access roads included in the approved 1998 SEIR and
the reevaluation access roads. Access is provided to all properties outside the
Suncoast Parkway 2 right-of-way.

H. Over/Under Analysis
The approved 1998 SEIR documented an over/under analysis for each of the streets
crossing the Suncoast Parkway 2. The over/under analyses were updated and all
17
locations remained the same except for Cardinal Street and Bitterroot Drive. In the
approved 1998 SEIR, the Suncoast Parkway 2 overpassed Cardinal Street. The
proposed improvements include Cardinal Street overpassing Suncoast Parkway 2. This
will reduce the overall costs of the interchange and provide improved access to adjacent
development. The approved 1998 SEIR had Suncoast Parkway 2 overpassing
Bitterroot Drive. The proposed improvements include Bitterroot Drive overpassing
Suncoast Parkway 2. With Bitterroot Drive overpassing Suncoast Parkway 2, the cost
of the improvement is reduced, access is maintained to all adjacent development and
constructibility is improved.
VI. Mitigation Status and Commitment Compliance
The following documents the specific commitments included in the approved 1998 SEIR
and their current status. (completed, modified, appended, deleted)
1. Wetland and Natural Systems Minimization Measures
A number of concepts will be considered during the design phase which will
minimize impacts to wetlands and other natural systems. Where appropriate, the
following concepts will be evaluated on a site by site basis in the design of the
Suncoast Parkway – Project 2 1) steeper side slopes, 2) retaining walls, 3)
guardrails, 4) bridging wetlands or longer bridges and/or oversized culverts for
ecosystem management purposes, 5) locating water management facilities out of
wetland areas or sensitive upland areas, and 6) limiting clearing and grubbing only
to those areas necessary to construction.
Status: This commitment remains unchanged.
2. Upland Habitat Mitigation
Through coordination with the environmental agencies and organizations involved in
the Suncoast Parkway – Project 2 Environmental Advisory Committee (EAC)
Partnering process, it has generally been agreed that the best concept for mitigation
of impacts to upland habitat will involve purchasing or contributing funds for the
preservation and management of upland habitats in public ownership.
The primary upland habitat which would be impacted by the proposed Suncoast
Parkway – Project 2 is sandhill. Through field investigations and literature review, it
has been determined that several state or federally listed species occur in the
sandhills of the project study area such as the Southeastern American kestrel, the
Sherman’s fox squirrel, the gopher tortoise, the gopher frog, the Florida mouse, the
Eastern indigo snake, the Florida pine snake and the short-tailed snake. By utilizing
the granture process which assumes that these species do occur in the suitable
habitat areas which would be impacted by the proposed project, extensive surveys
for these species as part of the PD&E Study were not required. With granture, the
next step entails determining the best possible way to mitigate for the impacts to
these species. Preservation of upland habitats on a type-for-type basis has been
determined to be the best option by the Suncoast Parkway – Project 2 EAC.
Through discussions with the EAC at the Partnering meetings, it appears that lands
such as the proposed Annutteliga Hammock Conservation and Recreational Lands
(CARL) purchase would be most suitable as preservation areas to serve as
18
mitigation for this project. The area of the Annutteliga Hammock within Citrus
County is primarily sandhill which would be the predominant habitat impacted by the
proposed project. The main body of the Annutteliga Hammock lies in Hernando
County. The Annutteliga Hammock CARL purchase, totaling over 28,000 acres is
currently ranked fourth on the list of priority projects. The Florida Department of
Transportation, (FDOT) Turnpike District will contribute funds toward this purchase
equivalent to the value of the acreage of land necessary to mitigate the habitat
impacts in accordance with the replacement value. The Annutteliga Hammock
CARL purchase area has many of the beneficial qualities important in identifying a
mitigation area such as connectivity to publicly owned lands, management potential,
good quality natural community of the same type impacted, and the area provides
habitat for many listed species.
A second mitigation option for impacts to upland natural communities could be the
Lecanto Sandhills. This area has been submitted for inclusion in the CARL program
but has not passed the initial phases of approval. The Lecanto Sandhill area,
though not as large as the Annutteliga Hammock, is approximately 777 ha (3 sq mi)
in size. Logging of the turkey oaks through this area has kept the mid-story from
becoming overgrown. A prescribed burning program would return this property to
good quality sandhill. Species recorded to occur on this property include the gopher
tortoise, the gopher frog, short-tailed snake and eastern indigo snake.
Additional upland mitigation options may be discovered during the design phase of
this project. Upland mitigation concepts will be finalized at that time.
Status: The FDOT, Turnpike District is now known as the Florida’s Turnpike
Enterprise (FTE). This commitment is modified to reflect the purchase of the
Annutteliga Hammock and the Lecanto Sandhills by the Florida Department of
Environmental Protection and these lands no longer being available for mitigation for
Suncoast Parkway 2. Mitigation of impacts to upland habitat will involve purchasing
additional lands for placement into public ownership or contributing funds for the
preservation and management of upland habitats in public ownership. Coordination
with the state and federal regulatory and resource agencies will continue through the
permitting phase of this project. Constructive input from these agencies will be
incorporated into the project planning to maximize the effectiveness of the land
acquisition for the greatest ecological benefit.
3. Wetland Mitigation
The primary wetland impacts are in the northern portion of the project area. The
majority of the wetlands in this area are small isolated marshes. Most impacts are to
the edge of the wetland and are less than one acre in size.
Recent legislation has passed regarding wetland mitigation for FDOT projects. This
new legislation (FS 373.4137, as created by SB 1986) essentially requires that DOT
will pay a total of $75,000 (adjusted periodically for inflation) to the FDEP and the
Water Management Districts for each acre of wetland impacted by a project.
Conceptual mitigation plan options are proposed through the Suncoast Parkway –
Project 2’s partnering process, for the FDEP and SWFWMD’s consideration in
preparing their mitigation plan under FS 373.4137. Three options are suggested at
this time.
19
One option for wetland mitigation would be the establishment of a mitigation bank or
the use of an existing mitigation bank within the Suncoast region.
A second option would be restoration of altered wetland systems within the project
vicinity. Restoration is often preferred over creation based on the greater likelihood
of success. Field review of the project area did not readily identify any potential
areas for restoration. Since the wetlands in the project vicinity are primarily isolated,
restoration would be scattered and for this reason may not be feasible.
A third option would be similar to the upland mitigation concept, consisting of
preservation. Though it would be advantageous to mitigate for wetland impacts at
the same location as the upland mitigation, this may not be feasible as the two best
upland mitigation locations, the Annutteliga Hammock and the Lecanto Sandhills, lie
on the Brooksville Ridge with few to no existing wetlands. The Cross Florida
Greenway (Phase II) proposed CARL purchase contains wetland areas and it may
be possible to work out a wetland mitigation agreement by contributing funds toward
the purchase of this CARL project.
Status: The Florida’s Turnpike Enterprise (FTE), (formerly the FDOT, Turnpike
District) proposed the project’s impact for inclusion under F.S. 373.4137 to
SWFWMD. The SWFWMD originally deferred development of a suitable mitigation
plan until a time closer to the expected permit submittal. In 2008, SWFWMD
delisted the project from F.S. 373.4137. FTE will develop an appropriate mitigation
plan to offset the unavoidable wetland impacts during the permitting process. All
options remain viable.
4. Additional Species – Specific Mitigation
Additional mitigative measures will be taken during the design phase on a speciesspecific basis to avoid and minimize impacts to listed species. These measures are
discussed below.
Gopher Tortoise (Gopherus polyphemus) – Some special fencing will be evaluated
for the length of the project within suitable habitat to prevent the gopher tortoises,
which are abundant in the sandhills and particularly concentrated in areas of the
power line corridor, from entering the right-of-way and potentially being killed. The
fencing should be in place prior to the onset of construction. The Florida Game and
Fresh Water Fish Commission (FGFWFC) will determine the type of permit and
mitigation that will be utilized prior to construction.
Status: The FGFWFC is now known as Florida Fish and Wildlife Conservation
Commission (FFWCC). This commitment remains unchanged.
Florida Gopher Frog (Rana capito aesopus) – In accordance with FS 373.4137, as
created by SB 1986, the Southwest Florida Water Management District (SWFWMD)
and the Florida Department of Environmental Protection (FDEP) will develop a
mitigation plan for wetland dependant listed species during the design phase of this
project. One option to mitigate potential impacts to the gopher frog could involve an
analysis of seasonal ponds potentially utilized for breeding by the gopher frog and
the impacts of the project on these wetlands either directly or through elimination of
20
access. Based on this analysis, additional suitable breeding ponds could be created
at appropriate location to benefit the gopher frog.
Status: The Florida Gopher Frog now has the scientific name Rana capito. The
FTE will avoid potential gopher frog seasonal ponds to the greatest extent practical.
Impacts to this species will be permitted by Florida Fish and Wildlife Conservation
Commission (FFWCC) and SWFWMD. In 2008, SWFWMD delisted the project from
F.S. 373.4137. Appropriate mitigation for the impacts will be provided. FTE will
evaluate opportunities to create replacement habitat within the project area.
Southeastern American Kestrel (Falco sparverius paulus) – Impacts to the
Southeastern American kestrel can be partially compensated for through
establishing and maintaining suitable nest boxes in the mitigation/preservation area.
Research shows that kestrels readily utilize nest boxes and may even prefer these
artificial dwellings. It is recommended that these nest boxes be located adjacent to
the power line. Kestrels seem to prefer the openness of the power line and nest
boxes located along power lines have been successful. Maintenance of the nest
boxes will be turned over to the FGFWFC or a local agency or group with
appropriate interests and resources.
Status: The FGFWFC is now known as Florida Fish and Wildlife Conservation
Commission (FFWCC). The status of this commitment remains unchanged.
Florida black bear (Ursus americanus floridanus) – The inclusion of a wildlife
crossing in the Suncoast Parkway – Project 2 just north of US 98 has been
discussed with the EAC and is included in the design concept. This crossing would
accommodate wildlife movements between Chassahowitzka National Wildlife
Refuge, Annutteliga Hammock and the Withlacoochee State Forest, though only the
Chassahowitzka National Wildlife Refuge currently supports a black bear population.
Status: The status of this commitment remains unchanged.
Florida scrub jay (Aphelocoma coerulescens coerulescens) – Additional surveys in
the vicinity of Scrub Jay Groups #2 and #4 are recommended closer to the time of
construction to better define the territorial boundaries and to document changes
which may occur over time. The territory of Scrub Jay Group #3 may extend to near
the proposed right-of-way for the CR 495 interchange. Since the CR 495
interchange would not be constructed until later, continued monitoring of this group
will provide a basis for finalizing the design of the interchange so that territorial
impacts would be avoided. Determinations on mitigation for the Scrub Jay will be
made based on the results of these additional surveys. The Rhoades tract, located
west of US 19 and near the Withlacoochee River, has been identified as a potential
area for off-site mitigation of impacts to the Florida Scrub Jay.
Status: Scrub jay surveys were completed, for the Fall 2007, Spring 2008, Fall 2008
and the Spring 2009 seasons. Based on these data, the species no longer occurs in
the project area and this commitment may no longer apply. The FTE will conduct
scrub jay surveys during the future final design and construction phases to confirm
presence.
21
Eastern indigo snake (Drymarchon corais couperi) – To minimize potential impacts
to the Eastern indigo snake, provisions will be made in the construction contract
advising the contractor of precautionary measures. Indigo snakes in the project area
could be unintentionally killed during construction activities. Because their habits
confound capture, no effort will be made to relocate indigo snakes prior to
construction. The construction contract will include special provisions for supplying
construction personnel with habitat and species descriptions and a warning of the
penalties for intentional harm. Contact with any individuals discovered during
construction will be avoided. If nests are discovered, FDOT biologists will be notified
immediately and will coordinate with US Fish and Wildlife Service (USFWS) and
FGFWFC in accordance with Section 7 of the Endangered Species Act of 1973, as
amended through 1982. To address agency concerns, the FDOT Turnpike District
has committed to implement the following protection measures:
• Provide eastern indigo snake educational information to employees prior to
the initiation of any clearing, construction or tortoise relocation activities. An
educational exhibit to be approved by the USFWS shall be posted at the site
accessible to all employees and a handout will be distributed to all
employees.
• The DOT Turnpike District will submit to the USFWS an education plan on
how the impact will be minimized through employee education 90 days (or as
soon as practicable) before any land clearing or construction activities begin.
The FDOT Turnpike District shall post and distribute educational information
to all its workers. The exhibit and brochure should include photographs of the
eastern indigo snake, information on life history and legal protection of the
species in Florida, how to avoid impact to the species, and agency telephone
numbers.
• All construction activities shall cease if live indigo snakes are found within the
project area. Work may resume after the snake or snakes are allowed to
leave the area on their own.
• Locations of live sightings shall be reported to the USFWS Jacksonville Field
Office at (904) 769-0552.
• If a dead eastern indigo snake is found on the project site, the snake shall be
frozen as soon as possible and the FDOT Turnpike District shall notify the
Jacksonville Field Office immediately for further instructions.
Status: FTE will mitigate for potential impacts to the eastern indigo snake in
accordance with the standard protection measures as outlined in the following

FDOT, Turnpike District is now known as the Florida’s Turnpike Enterprise (FTE).
The FGFWFC is now known as Florida Fish and Wildlife Conservation Commission
(FFWCC).
5. Section 7 Consultation
Section 7 Consultation will be initiated by the USACOE during the permitting process
in the design phase. Please refer to the USFWS letter of December 13, 1996
included in Appendix A.
Status: FTE will consult with USFWS under Section 10 of the ESA (1973) as
amended. Please refer to the ACOE letter dated May 28, 2009.
22
6. Listed Plants
There are a number of federal and state listed plants with the potential to occur
within the project area. Listed plants are typically found in unique areas or rare
natural habitats. Based on the list of plants introduced through the Partnering
meetings, scrub areas and areas where the limestone is close to the surface were
the most likely locations to encounter listed plants within the project area. As part of
the PD&E Study, all wetland areas within the proposed right-of-way have been
investigated for the presence of listed plants. During surveys for the Florida scrub
jay, transects covered all scrub areas and the presence of listed plants were noted.
Additionally, due to the high number of listed plants which typically occur near
limestone outcrops or where limestone is near the surface, areas of this nature
within the proposed right-of-way were investigated for the presence of listed plants.
Though there are a few listed plants with the potential to occur in the sandhills, there
were no organized surveys for these plants. Impacts to listed plants of the sandhills
will be mitigated through preservation and management of sandhill areas such as
the Annutteliga Hammock or the Lecanto Sandhills. Additional mitigation measures
may be determined in the future if listed plants are found to occur within the
proposed right-of-way that require specific habitat. There will be coordination with
the Department of Agriculture in accordance with Chapter 581.185 F.S.
The state-endangered pond spice has been observed within the proposed right-ofway. Special measures are recommended to minimize impacts for these plants. It
is recommended that the areas surrounding the state-endangered pond spice be
fenced during construction to reduce disturbance and Best Management Practices
be utilized to minimize the effects of sedimentation and erosion. Appropriate
measures should be taken to maintain the hydrology of the wetlands where the pond
spice occurs. There will be coordination with the Department of Agriculture on the
endangered pond spice in accordance with Chapter 581.185 F.S.
Status: FTE will avoid impacts to pond spice and other listed species, as observed,
to the greatest extent practical. If impacts are unavoidable, the FTE will consult with
appropriate conservation organizations to potentially relocate individuals or collect
various plant components for long term survival of the species.
7. General Wildlife
Wildlife in general could benefit through utilization of oversize culverts in suitable
locations that could serve as wildlife passages in addition to the wildlife underpass
recommended to be located within the Annutteliga Hammock north of US 98.
Through the partnering process, locations where oversized culverts would potentially
benefit wildlife are being preliminarily investigated with the final decision on
appropriate locations to be made during this project’s design phase.
Status: This commitment remains unchanged.
8. General Vegetation
The FDOT Turnpike District is committed to maintain as much native vegetation as
possible in the vicinity of the wildlife crossing and oversized culverts.
23
Status: This commitment remains unchanged. The FDOT, Turnpike District is now
known as the Florida’s Turnpike Enterprise (FTE).
9. Smoke Management
A Draft Smoke Management Plan for the project was developed during the
EAC/Partnering Process. The FDOT Turnpike District will continue to work with the
Division of Forestry to finalize a Smoke Management Plan for this project.
Status: This commitment remains unchanged. The FDOT, Turnpike District is now
known as the Florida’s Turnpike Enterprise (FTE).
10. Continuation of the Partnering Process
The FDOT Turnpike District is committed to the continuation of the EAC and the
Partnering Process during the design phase of the project.
Status: The commitment is modified to state as follows: “The Turnpike (FTE) is
committed to coordinating with each appropriate environmental agency during the
design phase of the project.“ The FDOT, Turnpike District is now known as the
Florida’s Turnpike Enterprise (FTE).
11. National Geodetic Survey Monuments
The FDOT Turnpike District will comply with the National Geodetic Survey’s request
to coordinate the removal of any of their monuments during construction. Please
refer to the National Geodetic Survey’s response letter provided in Appendix A.
Status: The status of this commitment remains unchanged. The FDOT, Turnpike
District is now known as the Florida’s Turnpike Enterprise (FTE).
12. Noise Abatement
The FDOT Turnpike District is committed to the construction of feasible noise
abatement measures at the interchange of SR 44 and Suncoast Parkway 2
contingent upon the following conditions:
• Detailed noise study during the final design process supports the need for
abatement,
• Reasonable cost analyses indicate that the economic cost of the barrier
will not exceed the guidelines,
• Community input and input from the owners of the property, regarding
desires, types, heights, and location of the barrier has been solicited by
the FDOT,
• Preferences regarding compatibility with adjacent land use, particularly as
addressed by officials having jurisdiction over such land uses has been
noted, and
• Safety and engineering aspects as related to the roadway user and the
adjacent property owner have been reviewed.
Status: The FDOT, Turnpike District is now known as the Florida’s Turnpike
Enterprise (FTE). A detailed design Noise Study Report was completed in February
2010. It was determined as part of this design phase noise study that the economic
cost of noise barriers for the Lecanto Hills mobile home park at the interchange of
24
SR 44 exceeded FDOT guidelines. This design noise study evaluated varying
lengths for noise barriers in order to determine if there was a feasible and
reasonable design. There was no noise barrier design configuration that was cost
reasonable for this project.
13. Meadowcrest Wastewater Treatment Plant
The Meadowcrest Wastewater Treatment Plant’s sprayfields are proposed to be
expanded to meet the future demand. Suncoast Parkway – Project 2 would impact
8.4 ha (20.8 ac) of these sprayfields. A preliminary mitigation plan has been
developed between FDOT Turnpike District and Citrus County and is included as a
project commitment. The Turnpike District will finalize the mitigation plan during the
Design Phase through further coordination with the County.
Status: The status of this commitment remains unchanged. The FDOT, Turnpike
District is now known as the Florida’s Turnpike Enterprise (FTE).
14. Proposed Homosassa Wastewater Treatment Site
The FDOT Turnpike District will mitigate for the 1.6 acre “corner clip” from the
proposed Homosassa Wastewater Treatment Plant site, dependent upon Citrus
County’s site plan for the facility.
Status: The FDOT, Turnpike District is now known as the Florida’s Turnpike
Enterprise (FTE). Preliminary coordination with Citrus County has indicated that the
county is not planning to use this site for a wastewater treatment facility; however,
the County may want to use this property or other nearby property for the county’s
use. The commitment is modified to reflect FTE will continue to coordinate with
Citrus County during the final design and right-of-way phases to either
mitigate/purchase or swap property for the project’s impact to the county’s property.
15. Homosassa Special Water District Peach Orchard Well Site
The proposed Suncoast Parkway – Project 2 is located outside the FDEP wellhead
protection zone defined by its Rule 62-521, F.A.C. However, the Homosassa
Special Water District’s (HSWD) wellhead protection planning process has identified
five-year, ten-year, and ten degree expansion capture zones for its Peach Orchard
wells, which are crossed by the preferred alignment. Although no local ordinance
has been adopted as a result of HSWD’s wellhead protection planning process, the
Turnpike District will consider enhancements to the project’s stormwater
management system during the design phase to further minimize the risk of
groundwater impacts in the area.
Consideration during the design phase of the project will be given to enhancing this
stormwater management system within the sub-basin that contains HSWD capture
zones to provide special measures for protecting groundwater quality, beyond the
minimum requirements of SWFWMD’s Rule 40D-4, F.A.C. The special measures to
be considered during design would include location of stormwater retention pond(s)
outside the 5-year capture zone and utilization of geo-fabric or other impermeable
materials for stormwater conveyances across the capture zones. By directing all
runoff via impermeable conveyances to ponds outside the 5year capture zone, the
potential for contamination of the Peach Orchard wells is nearly eliminated.
25
Status: The FDOT, Turnpike District is now known as the Florida’s Turnpike
Enterprise (FTE). FTE has received a confirmation letter (signed April 13, 2009)
from HSWD that the proposed design fulfills this commitment to locate ponds
outside of the 5-year capture zone.
16. Interchange Spacing
The conceptual design of the Preferred Alternative represents the “ultimate” facility,
meaning the Suncoast Parkway – Project 2 would accommodate the projected traffic
for the design year (2023). The FDOT Turnpike District is committed to initially
constructing interchanges where state roads intersect the project at US 98, SR 44
and US 19. Construction of the interchanges at Cardinal Street and CR 495 would
occur when traffic is sufficient to warrant their construction.
The County and the FDOT Turnpike District will coordinate the timing and
construction of the Cardinal Street and CR 495 interchanges.
Status: This commitment remains unchanged. The FDOT, Turnpike District is now
known as the Florida’s Turnpike Enterprise (FTE).

Attachment 1.A.3 – Contamination
The approved 1998 SEIR identified 23 potential contamination sites within the study
area evaluated. Twelve of these 23 sites were assessed a potential contamination risk
ranking of medium (11) or high (1). As part of the re-evaluation process, the project
team evaluated the project corridor for areas with the potential for contamination. The
evaluation encompassed the area extending 300 feet outside of the proposed right-ofway, for a total width of 1000 feet for the length of the proposed alignment.
The evaluation process was performed pursuant to FHWA’s Technical Advisory T
6640.8A, FDOT’s PD&E Manual, Part 2, Chapter 22 and standard environmental
assessment practices including regulatory agency records review, site reconnaissance,
literature review and personal interviews of individuals and business owners within the
project limits.
A total of 29 potential contamination sites were identified within the study area
evaluated. These sites are comprised of 10 of the original 23 sites and 19 new sites.
Of the original 23 potential contamination sites, 13 sites are outside the 1,000-foot wide
study area evaluated, six (6) have reduced rankings (one high ranked site has been
changed to a medium ranking, and five medium ranked sites have been changed to
low rankings), and four (4) sites have remained unchanged (two medium rankings and
two low rankings).
Of the 29 sites, nine of the sites were assessed a potential contamination risk ranking of
medium (8) or high (1). Table A.3.1 summarizes all of the potential contamination sites
within 300 feet of the proposed right-of-way. Of these sites, six are sites that have
changed since the approved 1998 SEIR, 19 are new sites and four (4) are sites where
the ranking remains the same as the approved 1998 SEIR.

A Level II field screening should be conducted for the nine potential contamination sites
with risk rankings of medium or high. This does not change the recommendations
included in the approved 1998 SEIR.
Attachment 1.A.5 – Floodplains
The approved 1998 SEIR identified an area of 21.4 acres of encroachment into the 100year floodplain, with a volume of 31.52 acre-feet, all located north of CR 486. During
the design process, more definitive data were obtained from field surveys of potential
floodplain areas. These data have resulted in increased and different impacts to
existing floodplains within the project area. Total floodplain impacts of the proposed
Suncoast Parkway 2 project are 34.6 acres with a total volume of 80.91 acre-feet.
The difference in floodplain impact volumes between the approved 1998 SEIR and the
current design is a result of updated contour information, survey data, and refined
design of the roadway.

Attachment 1.A.6 – Infrastructure
The approved 1998 SEIR identified the utility agencies owning facilities within the
project area. Utility contacts have been initiated with all utilities located within the
corridor. Table A.6.1 summarizes the utilities within the corridor.

Progress Energy is currently conducting an evaluation to determine the location of a
potential new transmission facility in the corridor. One potential location for the new
transmission facilities is within and/or adjacent to the existing Progress Energy right-ofway and easements. Recent coordination with Florida’s Turnpike Enterprise indicates
that this location may not be the preferred corridor for the new transmission facility. The
location of the new transmission facility is being coordinated with the design of
Suncoast Parkway 2.
30
Florida Gas Transmission is evaluating the installation of a second 36-inch natural gas
line in the general vicinity of the existing pipeline. The location of the new gas
transmission facility is being fully coordinated with the design of Suncoast Parkway 2.
The utilities which are impacted by the Suncoast Parkway 2 will be relocated during the
construction process.
Attachment 1.A.8 – Special Designations
In 2006, the Suncoast Parkway from Van Dyke Road in Hillsborough County to US 98 in
Hernando County was designated as a Florida Scenic Highway.
Attachment 1.A.10 – Wetlands
The approved 1998 SEIR identified 16.50 acres of wetland impacts within the project
area. During the design process, alignment revisions, pond and access road revisions,
and wetland jurisdictional determinations by regulatory agencies, the wetland impacts
have changed. Total direct wetland impacts of the proposed Suncoast 2 project are
28.22 acres and secondary impacts are 2.08 acres.
Attachment 1.A.11 – Wildlife and Habitat
The approved 1998 SEIR identified several flora and fauna species which may be
impacted by the proposed project. The impacted species were identified as gopher
tortoise (Gopherus polyphemus), Southeastern American kestrel (Falco sparverius
paulus), Eastern indigo snake (Drymarchon corais couperi), Sherman’s fox squirrel
(Sciurus niger shermani), Florida pine snake (Pituophis melanoleucus), gopher frog
(Rana capito), Florida mouse (Podomys floridanus), Florida scrub jay (Aphelocoma
coerulescens), Florida burrowing owl (Athene cunicularia), short-tailed snake (Stilosoma
extenuatum), bald eagle (Haliaeetus leucocephalus), Florida black bear (Ursus
americanus floridanus), Florida sandhill crane (Grus canadensis pratensis), American
alligator (Alligator mississippiensis), wading birds including the wood stork (Mycteria
americana), little blue heron (Egretta caerulea), snowy egret (Egretta thula), tri-colored
heron (Egretta tricolor), reddish egret (Egretta rufescens), limpkin (Aramus guarauna),
roseate spoonbill (Platalea ajaja) and white ibis (Eudocimus albus), and pond spice
(Litsea aestivalis). Additional surveys for threatened and endangered species and
species of special concern as well as their habitat indicated there has been minimal
change to the existing habitat available for these species.
As part of the design process, surveys have been conducted for the species cited above
as well as the black skimmer (Rynchops niger), brown pelican (Pelicanus occidentalis),
Homosassa shrew (Sorex longirostris eionis), least tern (Sterna antillarum), Peregrine
falcon (Falco peregrinus) and the red-cockaded woodpecker (Picoides borealis).
Extensive surveys were conducted for the Florida scrub jay, gopher tortoise and pond
spice. These surveys indicated that the Florida scrub jays located when the approved
1998 SEIR was completed are no longer resident in the study area. The results of
these surveys are included in the project files. Gopher tortoise surveys were conducted
during the same period as the Florida scrub jay surveys, resulting in a number of
burrows and animals being located. The gopher tortoise has been elevated by the state
of Florida from a species of special concern to a threatened species and mitigation will
31
be required during the permitting process for the project. Additional listed species such
as Sherman fox squirrel, eastern indigo snake, Florida pine snake, gopher frog, Florida
mouse, Florida burrowing owl, short-tailed snake, and the Florida black bear, will be
permitted using the FFWCC granture permit process.
Three state-listed protected plant species have been identified within the Sugarmill
Woods portion of the Withlacoochee State Forest. Two species, trailing milkvine
(Matelea pubiflora) and showy dawnflower (Stylisma abdita), are listed as Endangered,
and one species, garberia (Garberia heterophylla), is listed as Threatened. While these
species have not been observed within the project corridor, additional field activities will
be conducted to determine their presence/absence. If listed species are impacted by
construction, Florida’s Turnpike Enterprise will notify the Florida Department of
Agriculture and Consumer Services prior to construction initiation.
Preliminary surveys completed in the fall of 2007 indicate pond spice exists within seven
of the wetlands within the project corridor. Florida’s Turnpike Enterprise will notify the
Florida Department of Agriculture and Consumer Services concerning potential pond
spice impacts and mitigation.
The approved 1998 SEIR indicated a Section 7 Consultation under the Endangered
Species Act (ESA) of 1973 as amended should be conducted for the listed species
present in the study area. Coordination with the U.S. Army Corps of Engineers
indicates there are no wetlands under their jurisdiction and a Section 7 Consultation
under the ESA is not the appropriate effort. A Section 10 Consultation under ESA will
be undertaken with USFWS as part of the permitting process to identify the appropriate
mitigation for these species.
Attachment 1.B.1 – Historic/Archaeological
The approved 1998 SEIR did not identify any historic or archaeological sites eligible for
listing on the National Register of Historic Places due to the distance between the sites
and the proposed roadway or due to the common design types, alterations, or loss of
historic content.
The Cultural Resource Assessment Survey was updated for the project as part of this
reevaluation and identified the Etna Turpentine Camp as being eligible for listing on the
National Register of Historic Places. The Florida National Register Review Board met
on September 6, 2009 and found that the Etna Turpentine Camp met the criteria for this
listing. The State Historic Preservation Officer (SHPO) submitted the formal approved
nomination to the Keeper of the National Register in Washington D.C. The nomination
was subsequently approved on December 10, 2009 thereby placing the Etna Turpentine
Camp on the National Register of Historic Places.
An additional cultural resources assessment was completed as part of this reevaluation
to include the proposed pond locations. One previously recorded archaeological site
and a new archaeological site were located and evaluated during the assessment.
Based on the results, the sites have been determined not to represent significant
archaeological properties. This report was submitted to SHPO and a final concurrence
letter dated June 15, 2010 (included at end of Attachment 1) was received. The
concurrence letter included documentation of additional work that will need to take place
32
prior to project construction. The Turnpike Enterprise is committed to completing these
additional studies.
Attachment 1.B.2 – Recreation Areas
The approved 1998 SEIR identified existing recreation areas including the Homosassa
Tower in the Chassahowizka Wildlife Refuge and Bicentennial Park. These areas
remain unchanged. In addition, the Annutteliga Hammock tract and the Lecanto
Sandhills tract have been purchased as conservation land by the State of Florida. A
Memorandum of Understanding (MOU) was executed on August 3, 1998 between
Florida’s Turnpike Enterprise (then Florida’s Turnpike District) and the Board of
Trustees of the Internal Improvement Trust Fund of the State of Florida. This MOU
addressed the Suncoast Parkway construction through the Annutteliga Hammock tract.
The MOU may be modified to address the construction through the Lecanto Sandhills
tract.
Attachment 1.C.5 – Relocation
The approved 1998 SEIR stated that the proposed project would require right-of-way
taken from 504 individual parcels, and would result in 100 residential relocations, two
business relocations, and the acquisition of two billboard signs. Engineering design
changes have reduced the number of impacted parcels from 504 to 392. The 392
impacted parcels include 121 improved parcels which were referred to as relocations in
the 1998 approved SEIR. The 121 improved parcels are further categorized as 117
residential, two commercial and two billboards. These project impacts are required for
construction of the Suncoast Parkway 2.
Attachment 1.D.1 – Noise
The approved 1998 SEIR committed to the construction of feasible noise abatement
measures at the interchange of SR 44 (Lecanto Hills mobile home park) pending the
outcome of a detailed design noise study. The design phase noise study was conducted
in 2009. The noise study report was completed in February 2010. This traffic noise
study included an analysis of the Lecanto Hills mobile home park to determine where
traffic noise impacts occurred and to evaluate noise barriers. This design noise study
report evaluated varying designs of noise barriers adjacent to Lecanto Hills mobile
home park to determine if there was a feasible and reasonable configuration. In
addition, the design noise study report included an analysis of the entire corridor to
account for small alignment shifts, other design features that varied from the PD&E
conceptual design and to assure that all noise sensitive sites that were present prior to
the approved 1998 SEIR were evaluated using the latest criteria. It was determined that
there is no cost reasonable design for noise barriers at Lecanto Hills mobile home park
or any of the other impacted noise sensitive sites adjacent to the project area.
In summary, noise levels were evaluated for 349 residences and a medical facility as
part of this design noise study. Noise levels at three residences were predicted to reach
or exceed the 66 decibel (dBA) level for the year 2036 Build Alternative. Compared to
existing conditions, noise levels at 43 residences (includes the three residences that
reached or exceeded 66 dBA) are expected to experience a substantial increase in
33
traffic noise (i.e. 15 dBA or more) above existing conditions as a result of this project. A
noise barrier analysis was performed for the 43 residences identified as impacted.
Noise barriers were determined not be cost reasonable primarily because the low
density of residential development limits the number of residences that can be provided
at least a 5 dBA reduction. At the impacted residential area with the highest density
(Lecanto Hills mobile home park), noise barriers were ineffective primarily because of
noise generated on nearby SR 44. Consequently, noise barriers were not determined to
be reasonable and feasible and are not proposed at any location within the project
limits. The design phase noise study report is on file at the FDOT Turnpike Enterprise
office.
