NEPA – Section 4(f) CommitmentsSummary 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.

NEPA – Section 7 Gulf Sturgeon CommitmentsSummary 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 1st to August 31st

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


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


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 smalltoothsawfish.

14


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


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

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


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)

Project Requirements

Typical Sections – roadway and bridges

Dual Shared‐Use Paths

21


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


Roadway Project Requirements - PensacolaSouthbound 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 17th Ave. intersection – 2 lanes on SR 196 (Bayfront Pkwy) and 2 lanes on SR 30 (Gregory St)

Pedestrian pathways provided northbound and southbound.

23


Roadway Project Requirements - Pensacola

17th Ave Intersection Signalized Northbound right

turn lane on SR 30 (US 98)

Southbound SR 30 (US 98) dual left turn lanes

17th Ave includes triple left and double right turn lanes

No impacts to railroad bridge over 17th Ave

24


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


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.

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

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



Accommodation of the PD&E for SR 30 (US 98) at 17th

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 17th 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



Potential PD&E alternative – elevated roadway
