6 Final Section 4(f) Impacts 6

7 Existing Gulf Breeze Wayside Park 7

8 Improvements of Gulf Breeze Wayside Park 8

9 NEPA Section 4(f) Commitments Summary of major commitments: Work in temporary construction easements in the park shall not exceed two weeks per location Escambia County Fishing Bridge no impacts allowed Gulf Breeze Wayside Park Pull-through driveway for boat launching vehicles Pensacola Bay bridge tie-ins in the area of the park shall be extended to provide required parking 18 vehicle-trailer parking spaces 28 regular parking spaces Reconstruct the two entrance roadways on each side of the park Two 10 wide shared use paths across the new Pensacola Bay Bridge connecting Gulf Breeze Wayside Park to Pensacola Wayside Park Existing boat ramp shall be maintained and fully operational for emergency services Landscaping the Department will handle after the design-build contract is completed. 9

10 NEPA Section 7 Gulf Sturgeon Consultation Gulf Sturgeon tagging with USFWS on Yellow River 10

11 NEPA Section 7 Gulf Sturgeon Consultation 11

12 NEPA Section 7 Gulf Sturgeon Commitments Summary of major commitments: No nocturnal pile driving from October through May 5000ft low noise corridor; If full 5000ft feet not feasible, maintain minimum 1500ft low noise corridor Gulf Breeze landing shoreline waters pile driving ONLY allowed from June 1 st to August 31 st Noise attenuation and monitoring will be required. Design-Build Firm will handle noise attenuation measures and Department will handle noise monitoring. Design-Build Firm to propose various noise mitigation strategies during acoustic monitoring. Ramp up pile driving required Prior to construction, the Department will coordinate with USFWS to complete consultation. Includes Design-Build Firm providing required information for construction techniques. USFWS contact Mary Mittiga will handle all coordination for Gulf Sturgeon for the project 12

13 NEPA Other Species of Concern West Indian Manatee USFWS guidelines Standard Manatee Conditions for In- Water Work Sea Turtles USFWS guidelines Sea Turtle and Smalltooth Sawfish Construction Conditions 13

14 NEPA Other Species of Concern Smalltooth Sawfish USFWS guidelines Sea Turtle and Smalltooth Sawfish Construction Conditions Department will continue informal consultation with NMFS after design information is provided in order to seek a determination of not likely to adversely affect the sea turtle and smalltooth sawfish. 14

15 Permits FDOT currently applying for permits for the project Intent is to obtain the permits if possible prior to Design- Build Firm s notice to proceed. The Design-Build Firm will then be responsible for permit modifications as needed. Overall goal to expedite the replacement of the existing bridge US Coast Guard design build permit; Design-Build Firms are NOT allowed to contact USCG now and once procurement is underway. US Army Corp of Engineers (ACOE) dredge and fill permit; Design-Build Firms are allowed to contact ACOE FDEP ERP permit; Design-Build Firms are allowed to contact FDEP 15

16 Existing Bridge Maintenance Prior to Demo Structurally deficient bridge no permit loads allowed Goal to avoid posting the bridge to reduce live load capacity First order repairs repairing concrete spalls in superstructure to achieve more shear strength and repairing steel superstructure at the channel span. Substructure repairs not anticipated at this time. Vibration monitoring in accordance with FDOT Specs Design, permits and construction responsibility of the Design- Build Firm $5,000,000 Do not bid item $15,000,000 Milestone No Excuse Bonus 860 calendar days 16

17 Existing Bridge Maintenance Prior to Demo 17

18 Existing Bridge Maintenance Prior to Demo 18

19 Maintenance of Traffic Maintain all existing travel lanes and turn lanes Temporary lane closure restrictions 5:00AM to 8:00PM Special events no temporary lane closures allowed Maintain existing driveways and side roads at all times Posted speed limits during MOT maintain existing, but no lower than 10mph below Hurricane evacuation route Design-Build Firm prepare a Transportation Management Plan 19

20 Maintenance of Traffic Incident Management Road Ranger Service Patrols (RRSP) each end of the bridge 24 hours a day and 7 days a week; in addition, one backup RRSP vehicle required Active RRSP will occur daily between 5:00AM to 8:00PM and be available remaining hours of the day Develop an incident management plan in coordination with local law enforcement officials and other agencies having jurisdiction. Vehicle refuge area Active Traffic Management Monitor and manage traffic speeds to achieve uniform speeds with a variance of no more than 10mph across the bridge Monitor traffic impacts to planned incidents to prevent secondary incidents (i.e. temporary lane closures, construction operations, equipment delivery) Manage and clear unplanned traffic incidents (i.e. debris, stalled vehicles, abandoned vehicles and crashed vehicles) 20

21 Project Requirements Typical Sections roadway and bridges Dual Shared Use Paths 21

22 Project Requirements - Bridges Vertical Profile changes due to coastal hydrodynamics Main channel span vertical clearance existing 50ft and increasing to 65ft horizontal clearance existing 125ft and increasing to 150ft 22

23 Roadway Project Requirements - Pensacola Southbound travel lanes SR 196 (Bayfront Pkwy) widen to 3 lanes southbound SR 30 (US 98) realignment as necessary for bridge connections Northbound travel lanes North of 17 th Ave. intersection 2 lanes on SR 196 (Bayfront Pkwy) and 2 lanes on SR 30 (Gregory St) Pedestrian pathways provided northbound and southbound. 23

24 Roadway Project Requirements - Pensacola 17 th Ave Intersection Signalized Northbound right turn lane on SR 30 (US 98) Southbound SR 30 (US 98) dual left turn lanes 17 th Ave includes triple left and double right turn lanes No impacts to railroad bridge over 17 th Ave 24

25 Roadway Project Requirements Gulf Breeze SR 30 (US 98) 6 travel lanes to tie to existing Right turn lanes into Wayside park connections Pedestrian pathways to connect to existing features 25

26 Project Requirements Design speed 45 mph for the majority of SR 30 (US 98); crest vertical curves at the channel span and associated adjacent sag vertical curves of new bridges shall be 50 mph Minimum 10ft horizontal clearance between the new bridges for inspection purposes. Lighting aesthetically pleasing roadway, bridge (superstructure and substructure), shared use paths, Gulf Breeze Wayside Park, under bridge pedestrian and vehicular crossings. ITS elements Future Dynamic Message Signs (DMS) accommodations CCTV camera system Road Weather Information System (RWIS) Microwave Vehicle Detection System (MVDS) Travel Time Monitoring System (TTMS) Wrong Way Detection System Fiber optic infrastructure 26

27 Project Requirements Demolition of the existing bridge, fender system and dolphins Escambia County permitted artificial reef sites City of Gulf Breeze future widening of the existing causeway (subject to the City s procurement of a permit) Landscape opportunity plans Preservation of existing vegetation Determine future landscaping areas during project design Landscape design will occur after project completion by a separate contract Federal Aviation Administration (FAA) restrictions Survey Geotechnical services Utility Coordination Pavement Design Signing and Pavement Markings Signalization 27

28 Project Requirements Drainage design Roadway drainage Compensatory stormwater treatment capacity is being utilized in a City of Pensacola Airport Pond Bridge Hydraulics Report Registered Professional Engineer in Florida specializing in coastal engineering Structures design No partial height retaining walls Retaining walls no MSE walls Ship impact forces New structures shall be designed independently of each other Minimum low chord elevation Girder type and material consistency Fender system Wave vulnerability Extremely Critical If segmental bridge type proposed twin segmental boxes required for each bridge 28

29 Project Requirements Accommodation of the PD&E for SR 30 (US 98) at 17 th Ave Early PD&E in progress Alternatives being determined, but one potential alternative could tie-in an elevated roadway to the northbound Pensacola Bay Bridge. This connection would flyover the 17 th Ave intersection and potentially connect to SR 30 (Gregory St). Potential related topics of discussion: 1) traffic control accommodation to maintain new 3 northbound lanes while connecting an elevated roadway to the Pensacola Bay Bridge; 2) consideration of horizontal separation between northbound and southbound bridges; 3) Pensacola Bay end bent elevations 29

30 Project Requirements Potential PD&E alternative elevated roadway 30
