EXECUTIVE SUMMARY
In 1987, the Federal Highway Administration (FHWA) signed the Final Environmental Impact Statement (FEIS) for the Northwest Hillsborough Expressway (NWE)-currently known as Veterans Expressway for improvements from Cypress Street just south of the Tampa International Airport (TIA) to Dale Mabry Highway (State Road (SR) 597), approximately 16.9 miles. In 1992, the FHWA signed the Design Change Re-evaluation of the NWE FEIS to authorize design of all eight segments of the roadway between Interstate (I)-275 from Cypress Street north to Dale Mabry Highway (SR 597). Subsequently, Florida's Turnpike Enterprise (FTE) assumed responsibility for the project. Construction of the segment from Memorial Highway to Dale Mabry Highway (SR 597) was completed in October 1994. In 1999, a Design Change/Right-of-Way (ROW) Re-evaluation was completed and approved by the FHWA, which focused on the section of the project corridor from Cypress Street to Independence Parkway. This same section was advanced through a 2003 Design Change/Construction Authorization Re-evaluation. As such, the interchanges located between I-275 and Memorial Highway, including new access to the TIA, Spruce Street, SR 60 at Courtney Campbell Causeway (CCC), and Independence Parkway, were reconstructed by the Florida Department of Transportation (FDOT) between 2005 and 2010.
The purpose of this Design Change Re-evaluation is to update the portion of the FEIS from Cypress Street just south of TIA to north of Memorial Highway based on modifications to the ramps coming into the I-275/SR 60 interchange from southbound I-275 and the new direct toll lane ramp connection to TIA. This Natural Resources Evaluation (NRE) documents the proposed study area’s potential involvement with protected species, wetland and surface waters, and Essential Fish Habitat (EFH) from Cypress Street just south of TIA to Independence Parkway.
Protected Species
Please refer to Table ES-1 below for the listed species with potential involvement with the 2018 NWE Design Change Re-evaluation study area in comparison with the 1987 NWE FEIS. Additional species considered because of changes to the project or that were listed since 1987 are included in the 2018 Design Change Re-evaluation. Proposed effect determinations are provided. Only species potentially occurring in the segment of the NWE from Cypress Street just south of TIA to Independence Parkway are included from the 1987 NWE FEIS; species that were anticipated to occur only in the northern segments of the study area are not included. The 1992 and 1999 Re-evaluations concluded that “no federal threatened or endangered species occur within the project boundary”. The 2003 Re-evaluation concluded that “there are no changes to listed threatened and endangered species since the 1999 Re-evaluation”. No additional state-listed species were noted as potentially occurring in this segment in the previous re-evaluations.

Wetlands and Surface Waters
Table ES-2 below summarizes the wetland and surface water impacts in the 2018 NWE Design Change Re-evaluation study area in comparison to the 1987 FEIS and in the 1992, 1999, and 2003 Re-evaluations. The interchanges located between I-275 and Memorial Highway, including new access to the TIA, Spruce Street, and SR 60 at CCC, were reconstructed by FDOT between 2005 and 2010. The wetland impacts described in the 1987 NWE FEIS, and in the 1992, 1999, and 2003 Re-evaluations were permitted in 2003 and incurred during the 2005-2010 reconstruction. The wetland and surface water impacts estimated for this 2018 Re-evaluation are for the construction of proposed tolled express lanes, associated ramps, and new connections at Eisenhower South-Cypress Street and Mondigo Street north of La Salle Street. These impacts were not included in the 1987 NWE FEIS or previous re-evaluations.

*The acreages shown for the 1987 FEIS and 1992, 1999, and 2003 Re-Evaluations were approved by SWFWMD and USACE permitsand impacted during the construction in 2005-2010. The acreage shown for the 2018 Re-evaluation are impacts not previously evaluated and includes impacts to SMFs built during the construction of the general lanes from 2005-2010.
Essential Fish Habitat
The 1987 FEIS and the 1992 and 1999 Re-evaluations did not address EFH since the EFH rules had not been promulgated at that time. The 2003 Re-Evaluation identified EFH losses of 32.69 ac which included impacts to salt marsh, mangroves, mud and sand substrates, seagrass, and estuarine water column. Impacts to EFH were coordinated with the National Marine Fisheries Service (NMFS) via the review and approval of US Army Corps of Engineer (USACE) Permits 200105084 and 200205816 issued in 2003. These impacts were incurred during the construction of the general lanes and associated improvements between 2005 and 2010.
For the improvements included in this 2018 Re-evaluation, it was determined that new EFH impacts may occur due to impacts to Fish Creek, saltwater marshes, or mangroves. EFH impacts to Fish Creek are anticipated to be minimal as the crossings proposed are bridged crossings over unvegetated portions of the creek. Thus, the majority of impacts will be temporary. Mangrove impacts are estimated at 0.04 acre (ac); saltwater marsh impacts are estimated at 0.16 ac. Mitigation for mangrove and saltwater marsh wetlands will be provided via the use of the FDOT Mitigation Plan with Southwest Florida Water Management District (SWFWMD) in accordance with 373.4137, Florida Statutes (FS) or through the use of mitigation bank credits. These options and any others proposed during design and permitting will compensate for unavoidable impacts to wetlands. Additional compensation for impacts to EFH, if required, will be further coordinated with the NMFS, United States Fish and Wildlife Service (USFWS), and other appropriate agencies. Impacts to EFH are anticipated to be minimal.

1. INTRODUCTION
In 1987, the Federal Highway Administration (FHWA) signed the Final Environmental Impact Statement (FEIS) for the Northwest Hillsborough Expressway (NWE)-currently known as Veterans Expressway - for improvements from Cypress Street just south of the Tampa International Airport (TIA) to Dale Mabry Highway (State Road (SR) 597), approximately 16.9 miles. The original study area is illustrated in Figure 1-1. The NWE was proposed as a major, divided, limited-access roadway to serve local traffic in the north and northwest areas of Hillsborough County near Tampa, Florida. The expressway involved improving Eisenhower Boulevard to six and eight lanes and the addition of interchanges between Interstate (I)-275 and Hillsborough Avenue. The remainder of the expressway was a new four-lane divided roadway with interchanges to the local road system from north of Hillsborough Avenue to Dale Mabry Highway.
In 1992, the FHWA signed a Design Change Re-evaluation of the NWE FEIS to authorize design of all eight segments of the roadway from I-275 north to Dale Mabry Highway (SR 597). Subsequently, Florida's Turnpike Enterprise (FTE) assumed responsibility for the project. FTE renamed the roadway Veterans Expressway (SR 589). Construction of the segment from Memorial Highway to Dale Mabry Highway (SR 597) was completed in October 1994. In 1999, a Design Change/Right-of-Way (ROW) Re-evaluation was completed and approved by the FHWA, which focused on the section of the project corridor from Cypress Street to Independence Parkway. This same section was advanced through a 2003 Design Change/Construction Authorization Re-evaluation. As such, the interchanges located between I-275 and Memorial Highway, including new access to the TIA, Spruce Street, SR 60 at Courtney Campbell Causeway (CCC), and Independence Parkway, were reconstructed by the Florida Department of Transportation (FDOT) between 2005 and 2010.
The purpose of this Design Change Re-evaluation is to update the portion of the FEIS from Cypress Street just south of TIA to north of Memorial Highway based on modifications to the ramps coming into the I-275/SR 60 interchange from southbound I-275 and the new direct toll lane ramp connection to TIA. The Design Change Re-evaluation will document compliance with new federal laws, identify any changes that may have occurred on the project since the approval of the original environmental document and subsequent re-evaluations, as well as assess the impacts of any new alternative options and compare them to the previously approved improvements.
1.1 Location for the NWE Re-evaluation Project
The general area for the proposed project begins at Cypress Street south of the TIA and thence proceeds northerly and northeasterly in the northwest quadrant of Hillsborough County to north of Memorial Highway (as shown on Figure 1-1). This Natural Resources Evaluation (NRE) includes the same general area but terminates at Independence Parkway. The portion of the Veterans Expressway from Memorial Highway to Dale Mabry Highway (SR 597) has already been constructed.
1.2 Purpose of the Report
This NRE documents the existing wildlife resources and habitat types found within the study area for potential occurrences of and effects to federally-listed and state-listed protected plant and animal species and their suitable habitat in accordance with Part 2, Chapter 16 - Protected Species and Habitat of the FDOT Project Development and Environment (PD&E) Manual (June 2017).
This report also documents potential impacts to wetlands and surface waters for the proposed study area of the NWE from Cypress Street just south of the TIA to Independence Parkway in accordance with Part 2, Chapter 9 – Wetlands and Other Surface Waters of the FDOT PD&E Manual (June 2017).

An Essential Fish Habitat (EFH) Assessment is included as part of this report in accordance with Part 2, Chapter 17 – Essential Fish Habitat of the FDOT PD&E Manual (June 2017) and the requirements of the Magnuson- Stevens Fishery Conservation and Management Act of 1976 (MSFCMA), as amended through October 11, 1996 and reauthorized in 2007. The EFH assesses waters and substrate necessary to fish for spawning, breeding, feeding, and development to maturity.
1.3 Design Changes and Revised Design Criteria
The NWE, currently known as the Veterans Expressway, Design Change Re-evaluation is to update the portion of the FEIS from Cypress Street just south of TIA to north of Memorial Highway based on modifications to the ramps coming into the I-275/SR 60 interchange from southbound I-275 and the new direct toll lane ramp connection to TIA.. Additional ROW, comprised primarily of commercial properties with a smaller component of upland hardwood-conifer forest, will be needed to accommodate express lanes near the SR 60 interchange north to and from I‐275 and a new toll ramp into TIA. New ramps to provide tolled express lane access to and from Independence Parkway will be constructed south of Independence Parkway. No additional ROW is anticipated for the new Independence Parkway toll ramps.

2. EXISTING ENVIRONMENTAL CONDITIONS
2.1 Existing Land Use
A desktop and document review was conducted for the NRE study area using the Southwest Florida Water Management District (SWFWMD) land use database and current aerials. Field evaluations were conducted on December 18, 2017 at wetland areas associated with Cypress Street to better define the land use boundaries in these areas using the FDOT Florida Land Use, Cover and Forms Classification System (FLUCCS). The field boundaries were combined with the SWFWMD FLUCCS boundaries to evaluate the habitat types found within the study area. Where delineation data was available, those field-determined lines were used to calculate anticipated impact; in all other areas, the SWFWMD data boundary was utilized.
Existing land use and potential impacts to natural environments were evaluated by utilizing the proposed outermost limit of the corridor (e.g. edge of pavement (EOP) or retaining wall) with a 15-foot buffer to account for side slopes, construction areas, and other potential construction impacts.
Table 2-1 provides a summary of the existing land use within the study area of the 2018 NWE Design Change Re-evaluation.

TOTAL 79.64 100
The majority of land use in the NWE Re-evaluation Study Area is transportation (80.64%). The remaining land use is comprised of man-made ponds and ditches (11.28 %), commercial properties (6.29%), upland hardwood-conifer mixed forests (1.04%), bays and estuaries (0.45%), wetlands (0.25%), and residential (high density) (0.05%).
2.2 Natural and Biological Features
A variety of resources including the National Wetlands Inventory (NWI) maps, Natural Resources Conservation Service (NRCS) Soil Surveys for Hillsborough County, U.S. Geological Survey (USGS) topographical maps, SWFWMD FLUCCS data, and aerial photographs were utilized to identify the wetland and upland communities that occur within the study area. Field reviews were also conducted on December 18, 2017 to verify potential

impacts at the new connections proposed at Cypress Street and Mondigo Street/West La Salle Street. The descriptions of the natural communities within the study area are provided below.
2.3 Upland Communities
The only upland, undeveloped habitat within the project limits is Hardwood Conifer Mixed (FLUCCS 434).
Hardwood Conifer Mixed (FLUCCS 434)
Hardwood conifer mixed communities are described as upland forests in which neither canopy type is dominant. This habitat is located adjacent to the ramp connection proposed north of West La Salle Street at Mondigo Street within the study area. Hardwood conifer mixed communities are also adjacent to the study area east of Veterans Expressway as it continues north past the CCC. Because the construction is to be located between existing roadway lanes in this area, impacts to the hardwood conifer mixed forests are not anticipated in adjacent areas.
Hardwood Conifer Mixed forests in the study area are primarily comprised of a mix of exotic and/or undesirable nuisance species including Brazilian pepper (Schinus terebinthifolia), punk tree (Melaleuca quinquenervia), and Australian pine (Casuarina equisetifolia). Other species include cabbage palm (Sabal palmetto) and slash pine (Pinus elliottii).
2.4 Wetland and Surface Water Communities
Wetland and surface water communities are located adjacent to and within the study area. Wetland habitats within the study area include saltwater marsh (FLUCCS 642) and mangroves (FLUCCS 612). Natural surface water habitats
include Fish Creek, classified as an estuary (FLUCCS 540) near Old Tampa Bay and transitioning to rivers and
waterways (FLUCCS 510) near the TIA-Connector ramps. Man-made stormwater linear ponds (FLUCCS 510) and stormwater management facilities (SMFs) (FLUCCS 530) are also included in the review of natural areas as they may provide limited habitat for some wildlife.
Detailed information on the impact acreages of the wetland and surface water communities within the study
area are provided in Section 4 and are shown on the FLUCCS Map provided in Appendix A.
2.4.1 Surface Waters
Streams and Waterways [FLUCCS 510; RUBx (Riverine, Unconsolidated Bottom, Excavated)]
This category includes rivers, creeks, canals, roadside ditches and other linear waterbodies. The 510 designation is given to the portion of Fish Creek crossed by the George J. Bean Parkway adjacent to the TIA property in the Spruce Street-Airport Interchange. There is also a roadside ditch located parallel and adjacent to the northbound SR 60-Hillsborough ramp on the east side of the CCC Interchange. However, this ditch is not anticipated to be impacted.
Reservoirs [FLUCCS 530; PUBx (Palustrine, Unconsolidated Bottom, Excavated)]
Reservoirs are described as water impoundments that are used for irrigation, flood control, municipal and rural water supplies, recreation and hydro-electric power generation. The reservoirs within the study area are SMFs located within the interchanges and adjacent to the existing roadways. These SMFs are located with the Spruce Street-TIA-SR 60 Interchange, at the Eisenhower South-Cypress Street Ramp, within the CCC-Veterans Expressway-SR 60 Interchange, and at Cypress Street.
Northwest Hillsborough Expressway Re-evaluation Page 6 June 2018
Natural Resources Evaluation
Bays and Estuaries [FLUCCS 540; E1OW/UB (Estuarine, Subtidal, Open Water/Unconsolidated Bottom)]
Bays are bodies of water that are partially enclosed by land that is directly open or connected to the ocean. Estuaries are partly enclosed bodies of water along a coast where one or more streams or rivers enter and result in a mix of freshwater and saltwater. Fish Creek is classified as an estuary where the SR 60 ramps cross the creek, heading north toward the CCC. The project will not impact Tampa Bay.
2.4.2 Wetlands
Saltwater Marshes [FLUCCS 642; E2EM1P (Estuarine, Tidal, Emergent, Persistent, Irregularly Flooded)]
Saltwater marshes are intertidal areas colonized by grasses and other salt-tolerant plants. The dominant plants in these systems are typically emergent, herbaceous species, although shrubs can also be locally abundant. The main location of saltwater marshes adjacent to the study area is within the area south of the CCC and west of the Veterans Expressway southbound. Another small area of saltwater marsh is found at the proposed Eisenhower South-Cypress Street connection, adjacent and north of Cypress Street.
Mangrove [FLUCCS 612; E2SS3P (Estuarine, Tidal, Scrub-Shrub, Broad-Leaved Evergreen, Irregularly Flooded)]
Mangrove swamps are a coastal, hardwood community composed primarily of red mangroves (Rhizophora mangle) and black mangroves (Avicennia germinans). The major associates in this area include white mangroves (Laguncularia racemosa), buttonwoods (Conocarpus erectus), sea myrtle (Baccharis halimifolia), and marsh elder (Iva frutescens). A large mangrove area is located adjacent to and west of the study area, beginning south of the CCC and continuing south to Cypress Street.

The study area was assessed for the presence of suitable habitat for federally-listed and state-listed species and U.S. Fish and Wildlife Service (USFWS) Critical Habitat in accordance with 50 Code of Federal Regulations (CFR) Part 402 of the Endangered Species Act (ESA) of 1973, as amended, Chapters 5B-40: Preservation of Native Flora of Florida and 68A-27 Florida Administrative Code (FAC) Rules Relating to Endangered or Threatened Species, the Migratory Bird Treaty Act (MBTA) of 1918 and Part 2, Chapter 16 - Protected Species and Habitat of the FDOT PD&E Manual (June 2017).
The study area was evaluated for potential federally-listed and state-listed species as well as other protected species that may exist within the study area. The following resources were utilized to determine this assessment:
• FDOT FLUCCS, 3rd edition 1999
• SWFWMD Land Use Data (2013-2014)
• Aerial derived photographs (2016)
• Florida Natural Areas Inventory (FNAI), Hillsborough County, Florida
• Florida Fish and Wildlife Conservation Commission (FWC) Bald Eagle Nest locator website
• Wood Stork Colony Location Database (USFWS)
• Protected Species Technical Memorandum for the Design Change and ROW Authorization Re-evaluation for the 1996 Tampa Interstate Study (TIS) FEIS and Northwest HillsboroughExpressway FEIS (June 2016)
The evaluated species for the study area are discussed below with updated effect determinations. The updated

Natural Resources Evaluation
list of potential species was preliminarily identified with a data search of the FNAI biodiversity matrix conducted in March and April 2016 and a limited field review conducted December 18, 2017. The species with the potential to occur in the study area based on habitat types present are listed in Table 3-1 below with the likelihood of occurrence rated as low, moderate, high, or none. A low rating indicates that the species is known to occur in Hillsborough County, suitable habitat is not present or is limited on the corridor, and/or the species is unlikely based on what is known about its habits or life history. A moderate rating indicates the species is known to occur in Hillsborough County, suitable habitat for that species is present on the project corridor, but the species has not been observed in past studies or documented on the database. Species with a moderate rating may require Standard Construction Precautions during construction. Standard Construction Precautions anticipated to be implemented for the NWE are provided in Appendix B. A high rating indicates the species occurs in Hillsborough County, is suspected within the project corridor based on known ranges and existence of sufficient preferred habitat on the corridor, and has been previously observed or documented in the vicinity. A high rating also is assigned if the project is located within a consultation area for the species and suitable habitat exists in the study area for the species.

3.2 Federally-Listed Species
In November 2010, the FWC established an imperiled species rule which states that all species listed by the USFWS and National Marine Fisheries Service (NMFS) that occur in Florida are also included on the Florida Endangered and Threatened Species List as Federally-Designated Endangered, Federally-Designated Threatened, Federally-Designated Due to Similarity of Appearance, or Federally-Designated Non-Essential Experimental population species. Thus, all federally-listed species evaluated below are also state-listed species protected by the FWC.
The 1987 NWE FEIS identified two species potentially occurring within the study area that were federally-listed as endangered at that time - the wood stork (Mycteria americana) and the bald eagle (Haliaeetus leucocephalus). The study also identified one species in the study area that was federally-listed as threatened - the Eastern indigo snake (Drymarchon couperi). The conclusion of the 1987 NWE FEIS was that the project would have no adverse effect on federally- or state-listed species. The 1992, 1999, and 2003 Re-evaluations did not modify the original findings of the 1987 NWE FEIS for this segment or add new species for consideration for this segment. Additional species considered in the 2018 NWE Design Change Re-evaluation with updated listing statuses and effect determinations are provided below.
3.2.1 Gulf Sturgeon
The Gulf sturgeon (Acipenser oxyrinchus desotoi) is federally-listed as threatened. The sturgeon forages in the Gulf of Mexico and spawns in most coastal rivers, specifically in northern Florida. This species is more common in Gulf waters and rivers near the Panhandle over to Mississippi but has been seen as far south as Florida Bay. No USFWS Critical Habitat is documented within the study area. The Gulf sturgeon has the potential to enter the estuarine area of Fish Creek, which is crossed by SR 60/Veterans Expressway heading north to the CCC and the Veterans Expressway-Spruce Street-TIA Connector ramp crossings heading north into the TIA. At this phase of project development, details on the types of crossing, pile driving activities, and foundation design of the crossings are not known. Additional details will be available and evaluated during design at these crossing locations over Fish Creek. The FDOT will commit to watching for this species during construction of the project and adhere to the Construction Special Provisions Gulf Sturgeon Protection Guidelines (NMFS, USFWS) (Appendix B). With these provisions in place, the project may affect, not likely to adversely affect the Gulf sturgeon.
3.2.2 Smalltooth Sawfish
The smalltooth sawfish (Pristis pectinata) is federally-listed as endangered. Smalltooth sawfish normally inhabit shallow, tropical coastal waters and estuarine habitats such as seagrass beds, mangroves, and inshore bars. They can be found in sheltered bays, estuaries, and mouths of rivers; some sawfish are even known to go upstream into fresh water in larger riverine systems. This species was historically found throughout most of the Gulf of Mexico and the Atlantic Ocean but is now confined to peninsular Florida and only relatively common in areas of south Florida near the Everglades. The NMFS has designated coastal waters near Fort Myers and the Everglades as Critical Habitat for the smalltooth sawfish. No Critical Habitat is located near the study area. The smalltooth sawfish was not observed in the area, and the data as to its occurrence in the area are inconclusive. The smalltooth sawfish has the possibility of entering the estuarine waters of Fish Creek under the SR 60/Veterans Expressway crossing heading north to the CCC and the Veterans Expressway-Spruce Street-TIA Connector Ramp crossings heading north into the TIA. At this phase of project development, details on the types of crossing, pile driving activities, and foundation design of the crossings are not known. Additional details will be available and evaluated during design at these crossing locations over Fish Creek. With implementation of the NMFS’s Sea Turtle and Smalltooth Sawfish Construction Conditions (Appendix B) during construction, the NWE Re-evaluation proposed improvements may affect, not likely to adversely affect the smalltooth sawfish.
Natural Resources Evaluation
Northwest Hillsborough Expressway Re-evaluation Page 11 June 2018
3.2.3 Piping Plover
The piping plover (Charadrius melodus) is federally-listed as threatened. This species is found on open, sandy beaches as well as tidalflats and mudflats. They are found on both the Atlantic and Gulf coasts but are more common on the Gulf coast. This project is located within the USFWS Consultation Area for the piping plover, but no USFWS Critical Habitat or suitable habitat is identified within the project study limits.
There is no open, sandy beach habitat within the study area, and no suitable habitat for this species that will be impacted by the NWE. Therefore, the NWE Re-evaluation proposed improvements will have no effect on the piping plover.
3.2.4 Rufa Red Knot
The Rufa red knot (Calidris canutus rufa) is federally-listed as threatened. This species is a medium-sized shorebird that breeds and nests in dry, slightly elevated tundra locations, often on slopes with little vegetation. The species migrates annually between its breeding grounds in the Canadian Arctic and several wintering regions, including the Southwest U.S., the northwest Gulf of Mexico, northern Brazil, and Tierra del Fuego at the southern tip of South America. During both the spring and fall migrations, groups of red knots can be found along the coastal and inland U.S. migration corridors from Argentina to Canada. It is found primarily in intertidal, marine habitats, especially near estuaries and bays. Optimal nonbreeding habitat is close to feeding areas, protected from predators, has sufficient exposed feeding grounds at highest tide, and is free from excessive human disturbance. Critical habitat has not been established for the Rufa red knot.
The study area has minimal, suboptimal habitat that would be suitable for the Rufa red knot, and the NWE Re-evaluation proposed improvements are anticipated to have no effect on the Rufa red knot.
3.2.5 Wood Stork
Wood storks are federally-listed as threatened. Wood storks utilize freshwater and estuarine habitats for nesting, foraging, and roosting. Wood storks are typically colonial nesters and construct their nests in medium to tall trees located within inundated forested wetlands including cypress swamps, mixed hardwood swamps, mangroves, and sloughs. No rookeries or breeding colonies are located in the study area. However, eight wood stork colonies are located within a fifteen-mile radius of the study area, the defined distance for Core Foraging Area (CFA) for wood storks in Central Florida. Suitable foraging habitat (SFH) for wood storks includes wetlands and surface waters which have areas of water that are relatively calm, uncluttered by dense thickets of aquatic vegetation, and have permanent or seasonal depths between 2 and 15 inches.
The Corps of Engineers, Jacksonville District, USFWS, Jacksonville Ecological Services Field Office, and State of Florida Effect Determination Key for the Wood Stork in Central and North Peninsular Florida (September 2008) (Appendix B), was followed to assess potential effects to the Wood Stork. Because the study area is within eight CFAs, impacted areas will be evaluated for potential use as SFH for wood storks. SFH in the project area is anticipated to be greater than 0.5 acre (ac). The FDOT will coordinate with the US Army Corps of Engineers (USACE) and USFWS to determine the quantity of the SFH impacts and to evaluate the appropriate compensation required. With appropriate mitigation provided, the NWE Re-evaluation proposed improvements may affect, not likely to adversely affect the wood stork.
3.2.6 Sea Turtles
Sea turtles have the potential to be in the study area in the estuarine portion of Fish Creek. Sea turtles with the
potential to exist within the study area include the loggerhead (Caretta caretta), green turtle (Chelonia mydas) Kemp’s Ridley (Lepidochelys kempii), and the Hawksbill sea turtle (Eretmochelys imbricata). The green sea turtle
Natural Resources Evaluation
Northwest Hillsborough Expressway Re-evaluation Page 12 June 2018
and loggerhead are both federally-listed as threatened. The Kemp’s Ridley sea turtle and Hawksbill sea turtle are federally-listed as endangered. These turtles are found in the Gulf of Mexico and coastal waters of Florida. However, nesting beaches for any of the sea turtle species are not located within or near the project corridor. Therefore, potential involvement is limited to swimming turtles. The FDOT will implement the NMFS’s Sea Turtle
and Smalltooth Sawfish Construction Conditions and Manatee and Sea Turtle Watch Program Guidelines (Appendix B) during construction. With these provisions in place, the NWE Re-evaluation proposed improvements may affect, not likely to adversely affect sea turtles.
3.2.7 Eastern Indigo Snake
Eastern indigo snakes are federally-listed as threatened. The USFWS Eastern Indigo Snake Programmatic Effect Determination Key (USFWS 2013) (Appendix B) was followed to assess potential effects to this species. Suitable habitat is found in the project area; therefore, Protection Measures for the Eastern Indigo Snake (Appendix B) will be followed during construction. Neither Eastern indigo snakes nor their refugia, particularly gopher tortoise burrows, were observed during field reviews of the project; however, 100% gopher tortoise surveys were not conducted so the potential for gopher tortoise burrows was not eliminated. The project will not impact xeric habitat (scrub, sandhill, scrubby flatwoods) and has fewer than 25 gopher tortoise burrows potentially occurring in the project area based on results of field reviews conducted. If during additional field reviews, gopher tortoise burrows are observed, the FDOT will excavate the burrow in accordance with FWC gopher tortoise permitting guidelines. If during the excavation, an indigo snake is encountered, the snake will be allowed to vacate the area prior to additional site manipulation. Refugia other than gopher tortoise burrows will be inspected each morning prior to site manipulation; if occupied by the indigo snake, work will not commence until the snake has vacated the vicinity of the proposed work, as required by USACE permits to be issued for the project. Therefore, the NWE Re-evaluation proposed improvements may affect, not likely to adversely affect the Eastern indigo snake.
3.2.8 West Indian Manatee
The West Indian (Florida) manatee (Trichechus manatus) is federally-listed as threatened. West Indian manatees utilize coastal waters, bays, estuaries, rivers, and occasionally lakes. Portions of the study area are located within the USFWS Consultation Area for the West Indian manatee. The USFWS Consultation Area is extensive and covers the entire Hillsborough coastline, and manatees have been documented in the bay adjacent to the Howard Frankland Bridge (HFB) causeway and the CCC. It is possible that the manatee can access Fish Creek within the Study Area. At this phase of project development, details on the types of crossing, pile driving activities, and foundation design of the crossings are not known. Additional details will be available and evaluated during design at these crossing locations over Fish Creek.
The USFWS Manatee Key (Florida, April 2013), as amended (Appendix B), was utilized to make the effect determination for the West Indian manatee. The project is not anticipated to include dredging of Fish Creek and will not include activities which will increase access for watercraft. No impact is anticipated to aquatic submerged vegetation, emergent vegetation, or mangroves at the Fish Creek crossings. The USFWS’s Standard Manatee Conditions for In‐Water Work (Appendix B) will be implemented, and these guidelines will be utilized when the project is constructed over Fish Creek. The most current provisions will be followed during construction. Therefore, the NWE Re-evaluation proposed improvements may affect, not likely to adversely affect the West Indian manatee.
3.3 State-Listed Species
All federally designated species are considered protected by State. Species which are not federally-listed but are state-listed with the potential to occur in the study area are described below.
Natural Resources Evaluation
Northwest Hillsborough Expressway Re-evaluation Page 13 June 2018
The 1987 NWE FEIS evaluation included two species that were state-listed as threatened - the least tern (Sterna antillarum) and the Florida sandhill crane (Grus canadensis pratensis). However, the 1987 NWE FEIS concluded that the least tern would not occur in areas to be impacted by the project although it may be in the vicinity of the project. The Florida sandhill crane was considered to be present in the northern segments of the 1987 NWE FEIS study area but was not identified as potentially occurring in the study area of this NRE. The 1987 NWE FEIS concluded that there would be no adverse effect to state-listed species by the NWE. The 1992, 1999, and 2003 Re-evaluations did not modify the findings of the 1987 FEIS. An updated analysis of these species and others are provided below.
3.3.1 Wetland-Dependent Avian Species
State-listed species which were identified in the vicinity of the corridor or which have potential to occur are a variety of wetland dependent avian species including the roseate spoonbill (Platalea ajaja), little blue heron (Egretta caerulea), reddish egret (Egretta rufescens) and tricolored heron (Egretta tricolor). These species are all state-listed as threatened. Nesting occurs in a variety of habitats from freshwater forested wetlands to mangrove islands, with the majority of the listed species utilizing larger trees.
Wetlands and surface waters that provide foraging potential for these species include freshwater marshes, saltwater marshes, herbaceous ditches/swales, tidal flats, shallow estuarine waters, ponds and riverine systems. Potential foraging habitat is located within the shallow estuarine, mangrove, and saltmarsh habitat adjacent to the study area and existing SMFs which will either be replaced or modified as part of the design. However, nesting locations are not located within the corridor. While foraging areas utilized by these species may be temporarily affected by this project, there will be no permanent impacts to nesting areas or rookeries. There is no adverse effect anticipated to these avian species as a result of the NWE Re-evaluation proposed improvements.
3.3.2 Florida Sandhill Crane
The Florida sandhill crane is listed as threatened by the FWC. The Florida sandhill crane is commonly found in wet prairies, marshy lake regions, low-lying pastures (including improved pastures) and shallow water open areas. Foraging areas for the sandhill crane include hydric pine flatwoods, pastures and prairies, as well as upland grassed areas. A limited amount of suitable foraging habitat for the sandhill crane exists within the proposed project area; unavoidable impacts to those foraging habitats will be mitigated as required during the permitting process in design. No sandhill cranes nesting locations were observed during field observations and none would be anticipated based on the habitat available in the study area. With these considerations, there is no adverse effect anticipated to the Florida sandhill crane.
3.3.3 Least Tern
The least tern is listed as threatened by the FWC. The least tern inhabits areas along the coasts of Florida, including estuaries and bays. Least terns traditionally nested on sandy beaches and isolated stretches of the mainland shore. More recently, this species has been observed nesting on roofs and on causeways comprised of dredged material near marine or estuarine waters. Nesting areas have a substrate of well-drained sand or gravel with minimal vegetation. These migratory birds begin nesting in mid-April in central and southern Florida and leave in November through February. No unvegetated sandy beach habitat is within the study area. Because of the lack of suitable nesting habitat, there is no effect anticipated to the least tern.
3.3.4 Florida Burrowing Owl
The Florida burrowing owl (Athene cunicularia floridana) is a state-listed threatened species. Burrowing owls live in open treeless areas such as native prairies, golf courses, agricultural fields, and vacant lots. Suitable habitat may exist within the project study area for this species although it is anticipated to be minimal and marginal. No burrowing owls are documented in the study area. However, more extensive surveys are recommended during
Natural Resources Evaluation
Northwest Hillsborough Expressway Re-evaluation Page 14 June 2018
design to determine if this species is within the areas to be impacted as a result of this project. There is no adverse effect anticipated to the Florida burrowing owl with these precautions in place.
3.3.5 Gopher Tortoise
The gopher tortoise is a state-listed threatened species and is currently a candidate for federal listing. No gopher tortoise burrows were documented within the project; however, 100 percent surveys were not conducted. During design and prior to construction, the FDOT will conduct the appropriate gopher tortoise survey and obtain a FWC gopher tortoise relocation permit if needed. With the appropriate permitting and relocation effort, there is no adverse effect anticipated to the gopher tortoise.
3.4 Other Protected Wildlife Species
3.4.1 Bald Eagle
The bald eagle is no longer federally-listed and afforded protection by the ESA of 1973; protection for the species is provided through the Migratory Birds Program per the MBTA and Bald and Golden Eagle Protection Act (BGEPA). Bald eagles are also no longer state-listed. Bald eagles most commonly inhabit areas near the coast, bays, rivers, lakes or other open bodies of water. They nest in tall trees, typically live pines, which usually have open views to their surroundings. Eagles are also known to utilize artificial structures and other types of tall trees for nesting. There are no documented nests within 660 feet of the study area according to the FWC Eagle Nest Locator. No nests were identified within the study areas during field reviews. Pre-construction surveys should be conducted for the bald eagle.
The USFWS determined that construction activities greater than 660 feet away from bald eagle nests have no documented negative effects that would halt construction activities during the nesting season, as outlined in the USFWS’s Bald Eagle Monitoring Guidelines (2007). Monitoring of construction and nesting activities is therefore no longer warranted for projects involving construction beyond 660 feet of an active bald eagle nest during nesting season. Nesting season in Florida is from October 1 through May 15, although nesting may occur earlier or later than this period, especially in areas of south Florida. The USFWS Monitoring Guidelines shall be followed if any nests are observed within the project’s limits of construction; however, no nesting trees or other potential nesting sites are currently located within 660 feet of the project study limits.
3.4.2 Osprey
The osprey (Pandion haliaetus) is not federally-listed or state-listed but is protected under the MBTA. As such, its nests are afforded protection. Surveys for osprey nests will be conducted prior to construction. If nests are found, proper coordination and permitting with the FWC will be conducted.
3.5 Protected Plant Species
The project is located within an urbanized area of the City of Tampa, Hillsborough County. Natural communities are limited within the study area, and no protected plant species have been identified within the study area and none are anticipated to exist; therefore, there is no effect anticipated for protected plant species.
3.6 Critical Habitat
The project corridor was assessed for Critical Habitat designated by Congress in 17 CFR 35.1532. Review of the USFWS’s available Geographic Information Systems (GIS) data indicates there is no Critical Habitat within the project limits or surrounding areas; therefore, the proposed project will have no involvement with Critical Habitat.
Natural Resources Evaluation
Northwest Hillsborough Expressway Re-evaluation Page 15 June 2018
3.7 Agency Coordination
No agency coordination has occurred for the 2018 Re-evaluation improvements for this segment of the NWE. This NRE will be utilized to initiate coordination with the USFWS and FWC to obtain concurrence with the listed species evaluation.
4. WETLAND AND SURFACE WATER EVALUATION
4.1 Methodology
Pursuant to Presidential Executive Order 11990 entitled Protection of Wetlands, (May 1977) the U.S. Department of Transportation (USDOT) has developed a policy, Preservation of the Nation’s Wetlands (USDOT Order 5660.1A), dated August 24, 1978, which requires all federally-funded highway projects to protect wetlands to the fullest extent possible. In accordance with this policy, as well as Part 2, Chapter 9 – Wetlands and Other Surface Waters of the FDOT PD&E Manual (June 2017) the study area was evaluated for potential impacts to wetlands and surface waters.
Preliminary wetland boundaries were recorded during field ground-truthing efforts on December 18, 2017 at the proposed Eisenhower South-Cypress Street connector with the Veterans Expressway and at Mondigo Street, north of La Salle Street. Agency-verified boundaries will be recorded during additional field ground-truthing efforts during the permitting phase of the project. Preliminary boundaries were accomplished by implementing the State of Florida wetland delineation methodology Chapter 62-340, FAC, Delineation of the Landward Extent of Wetlands and Surface Waters, and the USACE methodology in accordance with the USACE Wetland Delineation Manual (1987) and 2010 Regional Supplement. Wetland functional assessments were performed on each wetland type based on the state Chapter 62-345, FAC, Uniform Mitigation Assessment Method (UMAM).
Wetland area estimates within the project study area and the existing ROW were developed using GIS technology. Wetland type descriptions are based on the FLUCCS Handbook (FDOT, January 1999) and the USFWS Classification of Wetlands and Deepwater Habitats of the United States. Five wetland or surface water community types were identified on the corridor. The location of the wetlands and surface waters are shown on the FLUCCS map (Appendix A).
4.2 Wetland Impact Evaluation
The 1987 NWE FEIS study identified eight wetlands in the segment between Cypress Street and Independence Parkway, with a total anticipated impact of 9.49 ac. The 1992 Design Change Re-evaluation identified an additional wetland area for a total of nine wetlands but did not provide acreages anticipated for impact for this segment of the study area. However, the 1999 Re-evaluation provided acreages by wetland for the 1992 proposed improvements in a comparison table and indicated that the total wetland impact estimated in the 1992 Re-evaluation was 13.05 acres.
The 1999 Design Change/ROW Authorization Re-evaluation plans included a number of changes in alignment which resulted in the identification of seven additional wetlands and other surface waters (OSWs) in the study area, for a total of sixteen wetlands and OSWs. The 1999 Re-evaluation plans included loop ramps north and south of the CCC; revised the Spruce Street/TIA interchange plans to accommodate an increased design speed; improved access to TIA; and included three additional SMFs. The 1999 Re-evaluation estimated wetland and OSW impacts of 17.37 ac within the study area. The FLUCCS codes of the nine wetlands previously identified in the 1987 FEIS and 1992 Re-evaluation could be determined for the 1999 evaluation using wetland identification numbers (Wetlands 1 – 9) from the prior studies. However, because FLUCCS codes were not provided in the 1999 Re-evaluation table of impacts, the FLUCCS
Natural Resources Evaluation
Northwest Hillsborough Expressway Re-evaluation Page 16 June 2018
codes for Wetland 10 through Wetland 16 were not able to be determined. Thus, the impact for the additional wetlands is indicated as “unknown FLUCCS” in the comparison table below (Table 4-2).
The 2003 Re-evaluation summarized impacts by type and acreage but not individual wetland identification. The 2003 Re-evaluation improvements included 33.19 ac of impact to wetlands, surface waters, and ditches. However, 4.92 ac were to upland-cut non-tidal ditches and pools which are not jurisdictional to the permitting agencies. The impacts considered as jurisdictional wetlands or OSWs totaled 28.27 ac. The impacts described in the 2003 Re-evaluation were permitted and approved under USACE Permits 200105084 and 200205816 and SWFWMD ERP permits 43000920.004 and 43002958.002. These impacts were incurred in the construction of the 2003 NWE improvements constructed between 2005 and 2010 and mitigated via 373.4137 (FS)-the FDOT Mitigation Plan implemented by SWFWMD as approved by the issued permits.
The 2018 NWE Design Change Re-evaluation proposed improvements are primarily within the confines of the existing roadways, interchanges, and ramps constructed between 2005 and 2010. The study area is entirely within the existing previously constructed lanes within and north of the Spruce Street Interchange. South of the Spruce Street Interchange, the project extends beyond the existing roadway boundaries into adjacent areas which are identified as commercial properties. The study area is also outside of existing roadway limits at the Mondigo Street connection and the Eisenhower-Cypress Street connection. The project will cross Fish Creek at two existing crossing locations. In-water work is anticipated to be limited to the crossings and anticipated only in non-vegetated areas of the creek. Reservoirs are man-made wet detention areas (SMFs) constructed in the interchange areas. Impacts anticipated from the proposed tolled express lanes improvements evaluated in the 2018 NWE Design Change Re-evaluation are provided below in Table 4-1. The map provided in Appendix A shows the locations of the wetland and surface water communities. A comparison of the impacts estimated in the 1987 FEIS and subsequent re-evaluations is included as Table 4-2 below.

The acreage shown for the 2018 Re-evaluation are impacts not previously evaluated and includes impacts to SMFs built during the construction of the general lanes between 2005-2010. Impacts from the 2003 Reevaluation were permitted by SWFWMD and the USACE.
4.3 Avoidance, Minimization, and Mitigation
During the design process, further efforts will be made to reduce the footprint within wetlands or surface waters to the extent practicable. Retention walls are proposed in mangrove areas to minimize side slopes. Express lanes are proposed in median areas between existing roadways to avoid impacts to adjacent wetlands or surface waters where feasible. Erosion and sediment controls and other best management practices (BMPs) will be implemented to contain impacts to the study area and minimize impacts to adjacent areas.
Mangrove, saltwater marsh, or other surface water compensation or mitigation will be provided through purchase of mitigation bank credits or through the FDOT Mitigation Program in accordance with chapter 373.4137 Florida Statute (FS). This chapter of the Statute states in part that, “mitigation for the impact of transportation projects proposed by the Department of Transportation can be more effectively achieved by regional, long-range mitigation planning rather than on a project-by-project basis. It is the intent of the Legislature that mitigation to offset the adverse effects of these transportation projects be funded by the Department of Transportation and be carried out by the use of mitigation banks and any other mitigation options that satisfy state and federal requirements in a manner that promotes efficiency, timeliness in project delivery, and cost-effectiveness.”
4.4 Wetland Functional Analysis (UMAM)
In February 2004, the Florida legislature [373.414 (18) FS] adopted a statewide UMAM to determine the amount of mitigation required to offset impacts to wetlands and other surface waters. UMAM is a standardized procedure for assessing the functions (expressed as a percentage compared to a natural, undisturbed wetland) provided by wetlands and other surface waters and the amount those functions are reduced or lost by proposed impact. The amount the functions are reduced or lost is referred to as Functional Loss (FL). Once it is determined that mitigation is necessary, the UMAM methodology is also used to quantify the amount of mitigation necessary to offset the FL of the impact. This can be expressed in acres or as credits from a mitigation bank or regional mitigation provider.
Natural Resources Evaluation
Northwest Hillsborough Expressway Re-evaluation Page 18 June 2018
UMAM is applied by the utilization of an assessment matrix, which analyzes three variables for wetlands and surface waters (i.e., indicators of wetland/other surface waters function):
• Location and Landscape• Water Environment• Vegetative Community Structure
Each variable yields an overall UMAM score for a wetland ranging from 0 to 10, based on the level of functions to fish and wildlife. For purposes of providing guidance, descriptions are given for four general categories of scores: Optimal (10), Moderate (7), Minimal (4), and Not Present (0). Areas of open water habitat such as Streams and Waterways (510) and ditches are considered Surface Waters or OSWs. Mitigation may be required for surface water impacts, but generally is not required to offset the loss of OSWs (ditches and SMFs) as these are typically replaced in-kind; therefore, OSWs are not included in the UMAM assessment.
UMAM values were determined for mangrove wetlands and saltwater marsh identified within the proposed study area. UMAM scores were assigned in accordance with the guidelines outlined in Chapter 62-345, FAC. (February 2, 2004). These representative UMAM scores will be re-evaluated at the time of final design and permitting based on the specific areas proposed for impact. Final UMAM scores will be prepared in conjunction with the regulatory agencies during the permitting process. The preliminary UMAM scores are summarized in Table 4-4. UMAM scoring forms supporting these scores are provided in Appendix C.
Table 4-4 Summary of Estimated UMAM Scores
Habitat Type Habitat Area (ac) UMAM Delta Preliminary Estimate of FL
Saltwater Marsh (642) 0.16 0.60 0.10
Mangrove (612) 0.04 0.73 0.03
4.5 Indirect and Cumulative Effects
Indirect impacts are caused by the action but occur later in time or farther removed in distance but are still reasonably foreseeable. The study area consists primarily of interstate roadways and ramp with express lanes proposed between the existing, constructed roadway. The causeway and roadway network is well established. Therefore, the project is not anticipated to stimulate growth or other development in the area but will provide more efficient and safe transportation.
Indirect impacts may occur to adjacent wetland areas from the causeway and roadway/ramps reducing the buffer area. An appropriate buffer will be considered during design/permitting and secondary impact calculations will be completed using UMAM to address any loss of wetland function. BMPs will be utilized to reduce or avoid indirect impacts from construction activities.
Cumulative impacts are those that result from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions. The project is the addition of express lanes and improvements to an existing major roadway system. It is not a new facility or one that will require substantial new ROW. No additional SMFs are proposed. The surrounding areas are already developed with existing access; access to areas suitable for development remains the same before and after the project but with increased efficiency from express lane availability. The project will impact small areas of mangroves and saltwater marsh in the study area. However, the impacts will be mitigated at suitable mitigation banks or utilizing appropriate sites developed through the FDOT Mitigation Plan by SWFWMD; thus, the wetland resource impacted will be replaced within the Tampa Bay area and not taken out of basin. Cumulative impacts are therefore not anticipated.

5. ESSENTIAL FISH HABITAT
An EFH Assessment is included in this report in accordance with Part 2, Chapter 17- EFH of the FDOT PD&E Manual and the requirements of the MSFCMA of 1996. EFH includes all types of aquatic habitat, such as open waters, wetlands, seagrasses, and substrate, necessary to fish for spawning, breeding, feeding, and development to maturity. An EFH assessment was not done in the 1987 FEIS or the 1992 and 1999 Re-evaluations. The 2003 Re-Evaluation identified EFH losses of 32.69 ac which included impacts to salt marsh, mangroves, mud and sand substrates, seagrass, and estuarine water column. Impacts to EFH were coordinated with the NMFS via the review and approval of the USACE Permits 200105084 and 200205816 issued in 2003. These impacts were incurred during the construction of the general lanes from 2005 and 2010. This evaluation considers new minor impacts associated with the 2018 Re-evaluation improvements that were not considered in the prior documents.
5.1 Magnuson-Stevens Act
The MSFCMA created conservation and management standards established through the Fishery Management Councils (FMCs) to implement the national standards in the Fishery Management Plans (FMP). The 1996 amendments to the MSFCMA set forth a number of mandates for the NMFS, eight regional FMCs, and other federal agencies to identify and protect important marine and anadromous fish habitat. The FMC’s with assistance from NMFS, are required to identify and delineate EFH for all managed species. Federal agencies that fund, permit, or carry out activities that may adversely impact EFH are required to consult with the NMFS regarding the potential effects of their actions on EFH and to respond in writing to NMFS’s recommendations.
5.2 EFH Involvement
The objective of the EFH Assessment is to describe how the actions associated with the proposed crossings of Fish Creek may affect EFH designated by the NMFS and Gulf Coast FMC within Old Tampa Bay estuarine systems. Land development activities may adversely affect EFH either directly or indirectly (e.g., loss of prey items), and this activity, either site specific or habitat-wide, is to be identified and evaluated individually and cumulatively. In response to the EFH assessment, NMFS and the FMC may provide recommendations and/or comments to the responsible federal permitting agency. The information provided by the NMFS is considered by the permitting agency and may be included in the recommendations as part of the USACE Section 404 permit conditions.
According to the National Oceanic and Atmospheric Administration (NOAA) guidelines for EFH (1998), EFH assessments must include:
• A description of the proposed action;
• An analysis of the effects, including cumulative effects, of the action on EFH, the managed species, andassociated species by life history stage;
• The federal agency’s reviews regarding the effects of the action on EFH; and
• Proposed mitigation if applicable.
The sections below include the description of the proposed activity, EFH existing conditions, analysis of effects, and the federal agency’s reviews regarding those effects on the EFH.
5.3 Existing Conditions
As per the SWFWMD FLUCCS maps and field reviews conducted December 2017, open water, saltwater marsh, and mangroves habitats are present in the study area. These areas are shown on the map provided in Appendix A.
Natural Resources Evaluation
Northwest Hillsborough Expressway Re-evaluation Page 20 June 2018
5.4 Field Surveys
A preliminary field review was conducted during field ground-truthing efforts on December 18, 2017 at the Eisenhower South-Cypress Street connection and Mondigo Street north of La Salle Street, where ramps and connections are proposed that were not included in prior investigations. These reviews were to field verify the SWFWMD 2013-2014 wetland land use in those areas.
5.5 Results
The following species with FMPs are known to exist in Tampa Bay in marine and estuarine habitats. Information on the life cycles and habitat preferences of the species are provided below. The FMPs for these species are related to commercial and recreational fishing limits and regulations. As the project impacts will have no relevance to the topics or criteria of the FMPs, specifics for the FMPs beyond species information is not detailed below.
Red Drum (Sciaenops ocellatus) is found throughout Florida estuaries within the Gulf of Mexico in primarily euryhaline waters. Adults are common in Tampa Bay and juveniles are common to abundant. Red drum is estuarine dependent. After hatching, larvae are carried into the shallow water of bays and estuaries with the tide. Once in an estuarine area they seek the shelter of grassy covers, tidal flats and lagoons for protection. Juveniles prefer shallow, protected, open waters of estuary covers and secondary bays with depths up to 3.0 meters. Adults are found in littoral and shallow nearshore waters off beaches and off shore in depths from 40 to 70 meters (130 to 230 feet).
Pink Shrimp (Farfantepenaeus duorarum) distribution is associated with seagrasses in general, and shoal grass in particular. They are distributed throughout the west coast of Florida and are common as juveniles in the Tampa Bay area. The juveniles occur in oligohaline to euhaline estuaries and bays. They seek the shelter of dense seagrasses with smaller juveniles preferring shoal grass and the adults preferring the refuge of turtle grass. Adults inhabit deep offshore marine waters commonly nine to 44 meters (145 feet) deep and inhabit substrates including shell‐sand, sand, coral‐mud and mud.
Stone Crab (Minippe mercenaria) is listed as common in Tampa Bay at all life stages. All life stages are marine to estuarine. Adults are usually found in deeper waters of estuaries or in inshore waters of the Gulf of Mexico. They burrow under rock ledges, coral heads or grass clumps, and at times in grass flats. Adults have been found to inhabit waters ranging in depth from five to 54 meters (177 feet). Juveniles are found in estuaries near pilings, rocks, and grass beds utilizing available cover and burrows. Migration tends to be short‐ranged and along shore from 1.6 to 8.0 kilometers (1 to 5 miles). Females migrate from grass flats to deeper waters to avoid especially high or low temperatures.
Spiny Lobster (Panulirus argus) occurs throughout the Caribbean Sea, along the shelf waters of the southeastern United States north to North Carolina, in Bermuda, and south to Brazil and the Gulf of Mexico. They are found from just below the water surface to depths of 500 meters (1,650 feet). The spawning season occurs from April through September in the southeastern U.S. and throughout the year in the Caribbean and the Florida Keys on offshore reefs. Adults move along shore and offshore seasonally. Caribbean spiny lobsters migrate to deeper water in order to evade the stresses of the cold and turbid waters.
Coastal Migratory Pelagics EFH consists of Gulf of Mexico waters and substrates extending from the U.S./Mexico border to the boundary between the areas covered by the Gulf of Mexico FMC and the South Atlantic FMC from estuarine waters out to depths of 100 fathoms (600 feet). Cero (Scomberomorus regalis), cobia (Rachycentron canadum), king mackerel (Scomberomorus cavalla), little tunny (Euthynnus alletteratus), and Spanish mackerel
Northwest Hillsborough Expressway Re-evaluation Page 21 June 2018
Natural Resources Evaluation
(Scomberomorus maculates) are species managed by the South Atlantic FMC. Spanish mackerel is known to occur within or near the study area. Spanish mackerel are prevalent throughout Florida waters inshore, offshore and nearshore. The species is frequently found over grass beds and reefs. Spanish mackerel are migratory fish that swim to the north in the spring and return to southern waters when the temperatures drop below 70 degrees Fahrenheit.
Reef Fish EFH consists of Gulf of Mexico waters and substrates extending from the U.S./Mexico border to the boundary between the areas covered by the Gulf of Mexico FMC and the South Atlantic FMC from estuarine waters out to depths of 100 fathoms (600 feet). The Gulf of Mexico reef fish primarily consists of grouper and snapper species. Gray Snapper (Lutjanus griseus) is a tropical, marine reef fish that occur from the U.S. mid‐ Atlantic south to Rio de Janeiro, Brazil. Juveniles are common to inshore waters throughout Florida, and adults are found in areas of moderate to high relief on the continental shelf. Spawning occurs during summer (June– September) in offshore waters around reefs, wrecks, and other bottom structures. Adult gray snapper are nocturnal predators that forage away from their reef habitats. Juveniles feed diurnally among seagrass beds and feed primarily on penaeid shrimp and crabs. Adult gray snappers feed on fish (largely grunts), shrimp, and crabs.
5.6 Analysis of Effect on EFH
As per informal consultation with the NMFS on February 26, 2018, the study area includes EFH. EFH is present in the open waters of Fish Creek, salt marshes, and mangroves. No seagrasses will be impacted.
Impacts to the water column are limited to work over the water within Fish Creek or possibly the placement of piles for new ramps or bridge crossings in two locations. The impacts to the water column will be temporary in nature with the only permanent impact being displacement of the water column by any piles being required for the placement of the proposed tolled express lane ramp. At this phase of project development, details on the types of crossing, pile driving activities, and foundation design of the crossings is not known. Additional details will be available and evaluated during design at these crossing locations over Fish Creek.
Degradation of water quality resulting from construction of the project or excess pollutant loading of stormwater runoff from the project has the potential to adversely affect project waters. Impacts to water quality from construction activities will be avoided and minimized through the use of BMPs. BMPs generally include phased construction, turbidity screens, silt fences, hay bales, cofferdams, and other construction techniques approved by the regulatory agencies.
5.7 Compensation for EFH Impacts
Mangrove and salt marsh mitigation will be mitigated through the purchase of mitigation credits at a mitigation bank and/or via the use of the FDOT Mitigation Plan with SWFWMD in accordance with 373.4137(FS). These options and any others proposed during design and permitting will compensate for impacts to wetlands. It is anticipated that the mitigation provided will provide sufficient compensation for EFH impacts. However, additional compensation for impacts to EFH, if required, will be further coordinated with the NMFS, USFWS and other appropriate agencies. With mitigation provided for wetland impacts, the impacts to EFH are anticipated to be minimal.

6. ANTICIPATED PERMITS
The USACE and the SWFWMD regulate wetlands and surface waters within the study area. Other agencies, including the USFWS, NMFS, United States Environmental Protection Agency (USEPA), and the FWC, review and comment on the wetland permit applications. In addition, the Florida Department of Environmental Protection (FDEP), through a delegation from the USEPA, regulates stormwater discharges from the construction sites. It is
currently anticipated that the following permits will be required for this project:
PERMITS ISSUING AGENCY Section 404 Dredge/Fill Permit USACE Environmental Resource Permit (ERP) SWFWMD National Pollutant Discharge Elimination FDEP System (NPDES) Permit Sovereign Submerged Lands Easement Port Tampa Bay (if applicable)
7. CONCLUSIONS AND COMMITMENTS
7.1 Protected Species and Habitat
The 1987 NWE FEIS effect determinations for listed species and the updated effect determinations for the 2018 NWE Re-evaluation are provided below in Table 6-1. The 1992, 1999, and 2003 Re-evaluations of the 1987 NWE FEIS did not modify the anticipated species in the segment and concluded that there would be no adverse effect to endangered or threatened species or their habitats as a result of the project.

7.2 Wetland and Surface Water Communities
The 1987 NWE FEIS estimated 9.49 ac of wetland and OSW impact for this segment. The 1992 Design Change Re-evaluation included an additional wetland area and estimated impacts at 13.05 ac. The 1999 Design Change/ROW Authorization Re-evaluation identified seven additional wetlands and OSWs to be impacted (total of sixteen wetlands) and increased the wetland impact estimate to 17.37 ac for this segment of the FEIS study area. The 2003 Re-evaluation improvements estimated 28.27 ac of impacts to jurisdictional wetlands and OSWs. The wetlands impacts evaluated in the 1987 FEIS and subsequent re-evaluations were permitted in 2003 and incurred during the construction general lanes and associated improvements between 2005 and 2010.
Because the proposed express lanes and ramps of the 2018 NWE Re-evaluation design are primarily within existing roadways, interchanges, and ramps of the previously constructed projects, impacts to wetlands are limited to 0.20 ac (0.04 ac mangrove; 0.16 ac saltwater marsh). Surface water impacts are limited to 0.36 ac to estuary, 0.30 ac to roadside ditches, and 8.68 ac to existing SMFs. These impacts were not previously considered in the 1987 NWE FEIS or prior re-evaluations. Because the improved improvements are within the boundaries of existing roadways, additional ROW needs are very limited with none of the additional ROW comprised of wetland.
Mangrove, saltwater marsh, or other surface water compensation or mitigation will be provided through purchase of mitigation bank credits or through the FDOT Mitigation Program in accordance with chapter 373.4137 (FS).
7.3 Essential Fish Habitat
An EFH assessment was not done in the 1987 FEIS or the 1992 and 1999 Re-evaluations. The 2003 Re-Evaluation identified EFH losses of 32.69 ac which included impacts to salt marsh, mangroves, mud and sand substrates, seagrass, and estuarine water column. Impacts to EFH were coordinated with the NMFS via the review and approval of the USACE Permits 200105084 and 200205816 issued in 2003. These impacts were incurred during the construction of the general lanes and associated improvements between 2005 and 2010.

It is anticipated that the mitigation provided will provide sufficient compensation for EFH impacts. However, additional compensation for impacts to EFH, if required, will be further coordinated with the NMFS, USFWS and other appropriate agencies. With mitigation provided for loss of seagrass and wetland impacts, the impacts to EFH are anticipated to be minimal.
7.4 Implementation Measures
• The FDOT will conduct a survey for gopher tortoises and coordinate with the FWC as appropriate basedon the results of the survey.
• The FDOT will conduct field reviews during design that will include surveys for burrowing owls and baldeagle nests within areas of suitable habitat.
• Erosion and sediment controls and other BMPs will be implemented prior to construction, andmaintained during and after construction, to prevent adverse impacts to adjacent water resources andproperties.
• No dredging is proposed for this project. If dredging is required, Section 7 Consultation will be re- initiated with the USFWS for the manatee.
7.5 Commitments
• The FDOT will incorporate the Construction Special Provisions Gulf Sturgeon Protection Guidelines(NMFS/USFWS).
• The FDOT will incorporate the Standard Protection Measures for the Eastern Indigo Snake (USFWS)during construction.
• The FDOT will incorporate the Standard Manatee Conditions for In-Water Work (FWC) during
construction.
• The FDOT will incorporate the Sea Turtle and Smalltooth Sawfish Construction Conditions (NMFS) duringconstruction.
• No nighttime in-water work will be performed. In-water work can be conducted from official sunriseuntil official sunset times.

Agency Wildlife Protection Plans
STANDARD PROTECTION MEASURES FOR THE EASTERN INDIGO SNAKE U.S. Fish and Wildlife Service
August 12, 2013 The eastern indigo snake protection/education plan (Plan) below has been developed by the U.S. Fish and Wildlife Service (USFWS) in Florida for use by applicants and their construction personnel. At least 30 days prior to any clearing/land alteration activities, the applicant shall notify the appropriate USFWS Field Office via e-mail that the Plan will be implemented as described below (North Florida Field Office: [email protected]; South Florida Field Office: [email protected]; Panama City Field Office: [email protected]). As long as the signatory of the e-mail certifies compliance with the below Plan (including use of the attached poster and brochure), no further written confirmation or “approval” from the USFWS is needed and the applicant may move forward with the project. If the applicant decides to use an eastern indigo snake protection/education plan other than the approved Plan below, written confirmation or “approval” from the USFWS that the plan is adequate must be obtained. At least 30 days prior to any clearing/land alteration activities, the applicant shall submit their unique plan for review and approval. The USFWS will respond via e-mail, typically within 30 days of receiving the plan, either concurring that the plan is adequate or requesting additional information. A concurrence e-mail from the appropriate USFWS Field Office will fulfill approval requirements. The Plan materials should consist of: 1) a combination of posters and pamphlets (see Poster Information section below); and 2) verbal educational instructions to construction personnel by supervisory or management personnel before any clearing/land alteration activities are initiated (see Pre-Construction Activities and During Construction Activities sections below). POSTER INFORMATION Posters with the following information shall be placed at strategic locations on the construction site and along any proposed access roads (a final poster for Plan compliance, to be printed on 11” x 17” or larger paper and laminated, is attached): DESCRIPTION: The eastern indigo snake is one of the largest non-venomous snakes in North America, with individuals often reaching up to 8 feet in length. They derive their name from the glossy, blue-black color of their scales above and uniformly slate blue below. Frequently, they have orange to coral reddish coloration in the throat area, yet some specimens have been reported to only have cream coloration on the throat. These snakes are not typically aggressive and will attempt to crawl away when disturbed. Though indigo snakes rarely bite, they should NOT be handled. SIMILAR SNAKES: The black racer is the only other solid black snake resembling the eastern indigo snake. However, black racers have a white or cream chin, thinner bodies, and WILL BITE if handled. LIFE HISTORY: The eastern indigo snake occurs in a wide variety of terrestrial habitat types throughout Florida. Although they have a preference for uplands, they also utilize some wetlands
1
and agricultural areas. Eastern indigo snakes will often seek shelter inside gopher tortoise burrows and other below- and above-ground refugia, such as other animal burrows, stumps, roots, and debris piles. Females may lay from 4 - 12 white eggs as early as April through June, with young hatching in late July through October. PROTECTION UNDER FEDERAL AND STATE LAW: The eastern indigo snake is classified as a Threatened species by both the USFWS and the Florida Fish and Wildlife Conservation Commission. “Taking” of eastern indigo snakes is prohibited by the Endangered Species Act without a permit. “Take” is defined by the USFWS as an attempt to kill, harm, harass, pursue, hunt, shoot, wound, trap, capture, collect, or engage in any such conduct. Penalties include a maximum fine of $25,000 for civil violations and up to $50,000 and/or imprisonment for criminal offenses, if convicted. Only individuals currently authorized through an issued Incidental Take Statement in association with a USFWS Biological Opinion, or by a Section 10(a)(1)(A) permit issued by the USFWS, to handle an eastern indigo snake are allowed to do so. IF YOU SEE A LIVE EASTERN INDIGO SNAKE ON THE SITE: • Cease clearing activities and allow the live eastern indigo snake sufficient time to move
away from the site without interference; • Personnel must NOT attempt to touch or handle snake due to protected status. • Take photographs of the snake, if possible, for identification and documentation purposes. • Immediately notify supervisor or the applicant’s designated agent, and the appropriate
USFWS office, with the location information and condition of the snake. • If the snake is located in a vicinity where continuation of the clearing or construction
activities will cause harm to the snake, the activities must halt until such time that a representative of the USFWS returns the call (within one day) with further guidance as to when activities may resume.
IF YOU SEE A DEAD EASTERN INDIGO SNAKE ON THE SITE: • Cease clearing activities and immediately notify supervisor or the applicant’s designated
agent, and the appropriate USFWS office, with the location information and condition of the snake.
• Take photographs of the snake, if possible, for identification and documentation purposes. • Thoroughly soak the dead snake in water and then freeze the specimen. The appropriate
wildlife agency will retrieve the dead snake. Telephone numbers of USFWS Florida Field Offices to be contacted if a live or dead eastern indigo snake is encountered: North Florida Field Office – (904) 731-3336 Panama City Field Office – (850) 769-0552 South Florida Field Office – (772) 562-3909

PRE-CONSTRUCTION ACTIVITIES 1. The applicant or designated agent will post educational posters in the construction office and throughout the construction site, including any access roads. The posters must be clearly visible to all construction staff. A sample poster is attached. 2. Prior to the onset of construction activities, the applicant/designated agent will conduct a meeting with all construction staff (annually for multi-year projects) to discuss identification of the snake, its protected status, what to do if a snake is observed within the project area, and applicable penalties that may be imposed if state and/or federal regulations are violated. An educational brochure including color photographs of the snake will be given to each staff member in attendance and additional copies will be provided to the construction superintendent to make available in the onsite construction office (a final brochure for Plan compliance, to be printed double-sided on 8.5” x 11” paper and then properly folded, is attached). Photos of eastern indigo snakes may be accessed on USFWS and/or FWC websites. 3. Construction staff will be informed that in the event that an eastern indigo snake (live or dead) is observed on the project site during construction activities, all such activities are to cease until the established procedures are implemented according to the Plan, which includes notification of the appropriate USFWS Field Office. The contact information for the USFWS is provided on the referenced posters and brochures. DURING CONSTRUCTION ACTIVITIES 1. During initial site clearing activities, an onsite observer may be utilized to determine whether habitat conditions suggest a reasonable probability of an eastern indigo snake sighting (example: discovery of snake sheds, tracks, lots of refugia and cavities present in the area of clearing activities, and presence of gopher tortoises and burrows). 2. If an eastern indigo snake is discovered during gopher tortoise relocation activities (i.e. burrow excavation), the USFWS shall be contacted within one business day to obtain further guidance which may result in further project consultation. 3. Periodically during construction activities, the applicant’s designated agent should visit the project area to observe the condition of the posters and Plan materials, and replace them as needed. Construction personnel should be reminded of the instructions (above) as to what is expected if any eastern indigo snakes are seen. POST CONSTRUCTION ACTIVITIES Whether or not eastern indigo snakes are observed during construction activities, a monitoring report should be submitted to the appropriate USFWS Field Office within 60 days of project completion. The report can be sent electronically to the appropriate USFWS e-mail address listed on page one of this Plan.

CONSTRUCTION SPECIAL PROVISIONS GULF STURGEON PROTECTION GUIDELINES
(PURSUANT TO NMFS AND USFWS) The Gulf sturgeon (Acipenser oxyrinchus desotoi) is listed under the Endangered Species Act as threatened. It is managed under the joint jurisdiction of the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (USFWS). Potential habitat for the Gulf sturgeon is located within the limits of this project. The following special provisions will be incorporated into any construction contract where involvement with sturgeon may occur: The FDOT has coordinated with the NMFS and USFWS early in the project development stage. The following provisions are intended to avoid/ protect known spawning habitats, nursery areas, feeding areas and thermal refuges.
1. The Florida Department of Transportation (FDOT) shall advise all FDOT project personnel and Contractor personnel on the project that there are civil and criminal penalties for harming, harassing or killing sturgeon. The FDOT and the Contractor will be held responsible for any sturgeon harmed, harassed, or killed as a result of the project activity.
2. The FDOT shall provide information to all FDOT and Contract personnel for identification of sturgeon.
3. Appropriate work shift personnel will be instructed in the appearance, habits, biology,
migratory patterns, and preservation of sturgeon. At least one of these trained personnel will be on site during construction activities to maintain a constant surveillance for these species, assure the cessation of activities (such as dredging, excess turbidity, and construction barge activity), which may endanger these species, and assure that uninhibited passage for the animals is provided.
4. Post signs on site warning of the presence of sturgeon, of their endangered status and
federal protection, and precautions needed.
5. Turbidity from construction activity will be adequately controlled to prevent degradation of the quality and transparency of the water. When sturgeon are present, turbidity curtains of appropriate dimension will be used to restrict the animals’ access to the work area. Pollution booms or turbidity curtains should use tangle resistant or hemp rope when anchoring, or employ surface anchors' to prevent entangling sturgeon. Continuous surveillance will be maintained in order to free animals which may become trapped in silt or turbidity barriers.
6. No dredging of the river bottom will be conducted for barge access.
September 2012
7. Drilled shaft pile construction will be used whenever prudent and feasible as determined by FDOT.
8. Care shall be taken in lowering equipment or material below the water surface and into
the stream bed. These precautions will be taken to ensure no harm occurs to any sturgeon which may enter the construction area undetected.
9. Construction debris shall not be discarded into the water.
10. If the use of explosives is necessary, the following protection measures will be employed
for projects in FDOT's District 3
a. In riverine areas: No blasting will occur in known spawning, staging, feeding, or nursery areas. In-water explosive work should be avoided between the months of April to
October. If explosive work becomes necessary within the April to October time frame,
a non-lethal "Fish Scare" charge will be detonated one minute prior to detonation of the underwater blast.
b. In estuarine areas:
No blasting will occur in known spawning, staging, feeding, or nursery areas. In-water explosive work should be avoided between the months of October to
April. If explosive work becomes necessary within the October to April time frame,
a non-lethal "Fish Scare" charge will be detonated one minute prior to detonation of the underwater blast.
c. In the event that a sturgeon is killed during blasting, the NMFS and the USFWS
will be notified immediately.
National Marine Fisheries Service US Fish and Wildlife Service by email at: 1601 Balboa Ave. [email protected] Panama City, Florida 32405 Tel: (850) 769-0552
11. Any sturgeon carcass will be secured on site or held in a freezer until an agency
representative arranges for its transport for analysis.
12. Following completion of the project, a report summarizing any involvement with sturgeon will be prepared for USFWS and NMFS.
STANDARD MANATEE CONDITIONS FOR IN-WATER WORK 2011
The permittee shall comply with the following conditions intended to protect manatees from direct project effects:
a. All personnel associated with the project shall be instructed about the presence of manatees and manatee speed zones, and the need to avoid collisions with and injury to manatees. The permittee shall advise all construction personnel that there are civil and criminal penalties for harming, harassing, or killing manatees which are protected under the Marine Mammal Protection Act, the Endangered Species Act, and the Florida Manatee Sanctuary Act.
b. All vessels associated with the construction project shall operate at "Idle Speed/No Wake” at all times while in the immediate area and while in water where the draft of the vessel provides less than a four-foot clearance from the bottom. All vessels will follow routes of deep water whenever possible.
c. Siltation or turbidity barriers shall be made of material in which manatees cannot become entangled, shall be properly secured, and shall be regularly monitored to avoid manatee entanglement or entrapment. Barriers must not impede manatee movement.
d. All on-site project personnel are responsible for observing water-related activities for the presence of manatee(s). All in-water operations, including vessels, must be shutdown if a manatee(s) comes within 50 feet of the operation. Activities will not resume until the manatee(s) has moved beyond the 50-foot radius of the project operation, or until 30 minutes elapses if the manatee(s) has not reappeared within 50 feet of the operation. Animals must not be herded away or harassed into leaving.
e. Any collision with or injury to a manatee shall be reported immediately to the Florida Fish and Wildlife Conservation Commission (FWC) Hotline at 1-888-404-3922.

DEMOLITION
MANATEE WATCH PROGRAM GUIDELINES
The contractor and subcontractors shall ensure that care is taken to conduct all construction
related activities with caution relative to any endangered or threatened species protected by the
Federal Endangered Species Act of 1973, the Florida Manatee Act, and the Federal Marine
Mammal Protection Act of 1972, as amended. All construction personnel shall be advised of the
potential presence of these species, of their endangered or threatened status, of their federal or
state protection, and of the need to refrain from any action, which would jeopardize the well
being of these species.
To minimize the potential impacts of bridge demolition and construction on manatees a
continuous Manatee Watch Program (MWP) will be established. The following conditions
constitute the MWP and shall be included as special provisions.
1. Seven days prior to the first bridge-related construction event, the contractors will
provide the U.S. Fish and Wildlife Service (USFWS) and the Florida Department of
Environmental Protection (FDEP) Office of Protected Species Management a list of the
chief and primary observers for the MWP and their qualifications. An outline of the
MWP will also be submitted seven days prior to the first such event.
The outline will include timetables for any blasting, dredging, or construction watercraft
activity, tide tables for blasting events indicating slack tides; timetables for the MWP
(start times for aerial survey as hereinafter required, and other survey positions); observer
positions; a copy of the MWP log sheet; and map to record manatee sightings.
2. A formal MWP coordination meeting will be held at least two days prior to the first
bridge-related construction event. Attendees will include the MWP chief and primary
observers, construction contractors, demolition subcontractors, FDOT, USFWS, FDEP
and other interested parties, such as the U.S. Coast Guard. All will be informed about
the possible presence of manatees in the area, and that civil or criminal penalties can
result from intentional or negligent annoyance, disturbance, harassment, molestation,
capture, collection, injury and/or death of an endangered species or any part thereof. The
construction contractors, demolition subcontractors and primary observer will present the
protocol and logistics of bridge-related construction activities and the outline specified in
condition No. 1.
3. During any blasting event, the manatee watch will consist of a minimum of six observers,
one chief observer and five additional observers. In addition to these observers, there
will be one MWP coordinator on-site to supervise the watch. Three of the six observers
shall have previous experience in observing/spotting manatees and should be documented
in the qualifications submitted in Condition #1. One of these observers shall have
previous aerial survey experience and shall be the observer conducting the aerial surveys.
The four additional observers shall be trained and informed in the methods of surveying
and locating manatees. During all other bridge-related construction events, the watch
shall consist of at least one observer posted at locations designated by a FDEP manatee
specialist.
4. All observers will follow the protocol established for the MWP and will conduct the
watch in good faith and to the best of their ability.
5. Each observer will be equipped with a two-way radio that will be dedicated exclusively
to the MWP. Observers will also be equipped with polarized sunglasses, binoculars, a
red flag for a backup visual communication system, and a sighting log with a map to
record sightings at the bridge construction site and vicinity.
6. All blasting events will be scheduled within the period of slack tide to allow for optimum
observing conditions. The chief observer will make the decision on optimum observing
conditions to initiate the survey for each blast event.
7. Continuous aerial survey will be conducted by helicopter one hour prior to each blasting
event in the vicinity of the blast site. In the event a helicopter is not available, FDEP and
USFWS will be contacted to determine another suitable method of aerial surveying. The
aerial survey area and route will be designed in conjunction with a FDEP manatee
specialist. After detonation, the aerial survey crew shall make a complete survey of the
safety and buffer zones before landing. The aerial survey crew shall either remain on
ground stand-by in the survey area or continue surveillance of the waterway until the end
of the blast period in case the need for aerial tracking of an injured manatee arises.
8. The additional primary observers will be located in various positions around the blast
site. These positions will be situated to provide maximum visibility of the blasting safety
zone and will have unobstructed views underneath the existing bridge. The exact
observer locations will be approved by FDEP and USFWS prior to each blast. One
observer will conduct a sonar survey (e.g. depth finder, fish locator) starting twenty
minutes prior to the blast of a 150 feet radius around the structure. The primary
observers will begin surveying the blast area one hour (60 minutes) prior to the blast
event and continue observing for one-half hour (30 minutes) after the blast event.
9. The blasting safety zone will be clearly marked with highly visible buoys. Using the
formula for an uncontrolled blast, the radius in feet of the blasting safety zone = 260
3Öw, where w = the weight of explosives to be used (TNT equivalent in pounds).
10. All of the observers will be in close communication with the blasting subcontractor in
order to halt the blast event. The blast event will be halted if a manatee spotted within
300 feet of the perimeter of the safety zone or within the safety zone (radius computed
above). The blasting event will be immediately halted at the direction of the primary
observers. The blast event will not take place until the animal(s) moves away from the
area of its own volition. Manatees must not be herded away or harassed into leaving. If
the animal(s) is/are not sighted a second time, the event will not resume until 30 minutes
after the initial sighting. (If manatees are to be guided out of the danger zone, it will be
done through an established protocol developed by the USFWS.)
11. Any problems encountered during bridge construction events will be evaluated by the
observers and contractors and logistical solutions will be presented to the USFWS and
FDEP. Corrections to the MWP will be made prior to the next event.
12. If an injured or dead manatee is sighted during construction, an observer will contact the
Florida Marine Patrol St. Petersburg Office at (727) 893-2904. In any such case, an
observer will also call the USFWS South Florida Field Office at (772) 562-3909. The
observer will act according to the situation and will maintain contact with the injured or
dead manatee. The foregoing telephone numbers shall be posted at all on-site telephones.
13. If an injured or dead manatee is rescued/recovered within three miles up or down the
waterway from the bridge site during construction or if the injury/death of any manatee in
the vicinity is documented to be caused by construction activity, that activity will be
postponed until cause of injury or mortality can be determined by FDEP and USFWS.
If injuries are substantially documented, all contributing construction activities will be
suspended and the principle parties will meet to determine a better way to conduct the
activity.
14. Operators of watercraft will be responsible for any collisions with manatees. Vessels
associated with the project should operate at slow (no wake) speed while in shallow
water, especially where the draft of the boat provides less than 3 feet of clearance with
the bottom. Workboats should load and off-load at designated sites. Vessels used to
transport personnel shall be shallow-draft vessels of the light displacement category, and
shall follow routes of deep water to the maximum extent possible where navigational
safety permits.
15. When turbidity barriers are used to prevent or minimize degradation of water quality, the
barriers shall be of appropriate dimension to restrict the animals’ access to the work area
and to allow egress of any manatees, which may enter the work area. Under such
conditions, the barriers should use tangle-resistant or hemp rope when anchoring, or
employ surface anchors to prevent entangling manatees. Continuous surveillance will be
maintained in order to free animals, which may become trapped in silt or turbidity
barriers.
16. Construction debris shall not be discarded into the water.
17. Signs will be posted on-site warning of the presence of manatees, their endangered status,
and precautions needed.
18. Within two weeks (14 days) after completion of all bridge-related construction, the chief
observer will submit a report to the USFWS and FDEP providing the names of the
observers and their positions during the event, number and location of manatees seen and
what actions were taken.
19. If any one of the above conditions is not met prior to or during the applicable activity, the
chief observer of the MWP will have the authority to terminate the activity. The
construction contractors will assume any liability for a violation of the above protective
measures.
NO DEMOLITION
MANATEE WATCH PROGRAM GUIDELINES
The contractor and subcontractors shall ensure that care is taken to conduct all construction and
related activities with caution relative to any endangered or threatened species protected by the
Federal Endangered Species Act of 1973, the Florida Manatee Act, and the Federal Marine
Mammal Protection Act of 1972, as amended. All construction personnel shall be advised of the
potential presence of these species, of their endangered or threatened status, of their federal or
state protection, and of the need to refrain from any action, which would jeopardize the well
being of these species.
To minimize the potential impacts of bridge construction on manatees, a continuous Manatee
Watch Program (MWP) will be established. The following conditions constitute the MWP and
shall be included as special provisions; no blasting or demolition activities are required.
1. Seven days prior to the first bridge-related construction event, the contractors will
provide the U.S. Fish and Wildlife Service (USFWS) and the Florida Department of
Environmental Protection (FDEP) Office of Protected Species Management a list of the
chief and primary observers for the MWP and their qualifications. An outline of the
MWP will also be submitted seven days prior to the first such event.
The outline will include time tables for any dredging, or construction watercraft activity;
time tables for the MWP (start times for aerial survey as hereinafter required, and other
survey positions); observer positions; a copy of the MWP log sheet; and map to record
manatee sightings.
2. A formal MWP coordination meeting will be held at least two days prior to the first
bridge-related construction event. Attendees will include the MWP chief and primary
observers, construction contractors, FDOT, USFWS, FDEP and other interested parties,
such as the U.S. Coast Guard. All will be informed about the possible presence of
manatees in the area, and that civil or criminal penalties can result from intentional or
negligent annoyance, disturbance, harassment, molestation, capture, collection, injury
and/or death of an endangered species or any part thereof. The construction contractors,
and primary observer will present the protocol and logistics of bridge-related construction
activities and the outline specified in condition No. 1.
3. All observers will follow the protocol established for the MWP and will conduct the
watch in good faith and to the best of their ability.
4. Each observer will be equipped with a two-way radio that will be dedicated exclusively
to the MWP. Observers will also be equipped with polarized sunglasses, binoculars, a
red flag for a backup visual communication system, and a sighting log with a map to
record sightings at the bridge construction site and vicinity.
5. Any problems encountered during bridge construction events will be evaluated by the
observers and contractors and logistical solutions will be presented to the USFWS and
FDEP. Corrections to the MWP will be made prior to the next event.
6. If an injured or dead manatee is sighted during construction, an observer will contact the
Florida Marine Patrol St. Petersburg Office at (727) 893-2904. In any such case, an
observer will also call the USFWS South Florida Field Office at (772) 561-3909. The
observer will act according to the situation and will maintain contact with the injured or
dead manatee. The foregoing telephone numbers shall be posted at all on-site telephones.
7. If an injured or dead manatee is rescued/recovered within three miles up or down the
waterway from the bridge site during construction or if the injury/death of any manatee in
the vicinity is documented to be caused by construction activity, that activity will be
postponed until cause of injury or mortality can be determined by FDEP and USFWS.
If injuries are substantially documented, all contributing construction activities will be
suspended and the principle parties will meet to determine a better way to conduct the
activity.
8. Operators of watercraft will be responsible for any collisions with manatees. Vessels
associated with the project should operate at slow (no wake) speed while in shallow
water, especially where the draft of the boat provides less than 3 feet of clearance with
the bottom. Workboats should load and off-load at designated sites. Vessels used to
transport personnel shall be shallow-draft vessels of the light displacement category, and
shall follow routes of deep water to the maximum extent possible where navigational
safety permits.
9. When turbidity barriers are used to prevent or minimize degradation of water quality, the
barriers shall be of appropriate dimension to restrict the animals' access to the work area
and to allow egress of any manatees, which may enter the work area. Under such
conditions, the barriers should use tangle-resistant or hemp rope when anchoring, or
employ surface anchors to prevent entangling manatees. Continuous surveillance will be
maintained in order to free animals, which may become trapped in silt or turbidity
barriers.
10. Construction debris shall not be discarded into the water.
11. Signs will be posted on-site warning of the presence of manatees their endangered status,
and precautions needed.
12. Within two weeks (14 days) after completion of all bridge-related construction, the chief
observer will submit a report to the USFWS and FDEP providing the names of the
observers and their positions during the event, number and location of manatees seen and
what actions were taken.
13. If any one of the above conditions is not met prior to or during the applicable activity, the
chief observer of the MWP will have the authority to terminate the activity. Any liability
for a violation of the above protective measures will be assumed by the construction
contractors.

There are no impediments to the hydrology and the water quality within the bay is good. There were no
obvious pollutants (oil/grease). Vegetation appears healthy.
There is sparse Brazilian pepper in the area, but the majority of the assessment area are native species typical of
a mangrove wetland. The plants are healthy and show no obvious signs of stress.
