Current Train Routing over Portageville Bridge

N

Existing Condition

Purpose

Provide a modern rail crossing of the Genesee River for Norfolk

Southern on the Southern Tier route between Buffalo and

Binghamton, capable of carrying current industry standard freight

rail loads, to the greatest degree possible meeting FRA Class 4

speeds, while reducing ongoing maintenance efforts and costs.

Needs•The bridge is a critical component of Norfolk Southern’s

Southern Tier route.

•The bridge is at the end of its useful life as a freight rail

structure.

•The bridge requires continuous inspection and frequent

repair, which is dangerous to bridge maintainers.

•Because of its age and structural weakness, the bridge

imposes speed and weight restrictions on the entire

Southern Tier line.

•The bridge poses safety concerns for park users, who

trespass on the bridge to cross the Genesee River gorge.

Project Goals•Eliminate operational constraints along the Southern

Tier route caused by the existing Portageville Bridge;

•Optimize existing infrastructure and planned improve-

ments to the Southern Tier route as part of Norfolk

Southern’s overall operational strategy in New York and

in this region of the country;

•Minimizedifficultandcostlymaintenance;and

•Minimize dangerous interaction of railroad activities on

the Portageville Bridge and Letchworth State Park

patrons that trespass on it.

Purpose and Need

Current Train Routing over Portageville Bridge

Demolition Options for Piers in River (Alternative 4)


WetlandsImpact:

• Filling of 0.05-acre freshwater wetland near parking area.

Mitigation:

•Implement permit conditions, if any, to be set by U.S. Army Corps of Engineers.

Surface Waterbodies and WatercoursesImpact:

•Disturbance to surface soils during construction may result in erosion and sediment loading into the Genesee River.

•If bridge piers are removed, river habitats could be disturbed.

Mitigation:

•Implement a Stormwater Pollution Prevention Plan (SWPPP).

•If existing piers are removed under Alternative 4, obtain the required permits and implement suitable mitigation, such as turbidity curtains, pursuant to permit requirements.

General Ecology and Wildlife ResourcesImpact:

•The new railroad alignment and bridge would remove approxi-mately 3 acres of forested habitat and disturb 1.1 acres of cliff habitat.

Mitigation:

•Implement a tree planting and revegetation program.

•Establish an invasive species control program.

Highbridge Parking Area


Historic and Cultural Resources Impacts:

•Removal (Alternative 4) or alteration (Alternative 5) of the existing Portageville Bridge, which is a contributing resource in the state- and federally-designated historic designation for Letchworth State Park.

•Alteration of park features, which are contributing elements of the historic Letchworth State Park, including:

•Removal and reorientation of a portion of Park Road,

•Removal and relocation of the Highbridge Parking Area and a historic marker in the parking lot,

•RemovalofhistoricfieldstonewallsalongportionsofParkRoadand the Gorge Trail, and

•Relocation of the trailheads of the Gorge and Mary Jemison

Trails.

Mitigation:

•Undertake Historic American Engineering Record (HAER) and/or Historic American Building Survey (HABS) documentation of the Portageville Bridge and other affected historic resources of Letchworth State Park.

•Install an interpretive kiosk that would display text and photographs to document the history, design, and use of the Portageville Bridge.

•For Alternative 4, salvage features of the bridge for display or use in Letchworth State Park.

•Reuse stone from stone walls for replacement walls, to the extent feasible.

•Use an appropriate paint color for the new bridge and apply form liners and coloring to surfaces of all approach piers and abutment

stems to resemble rock.

Parks and Recreational ResourcesImpacts:

•Acquisition of approximately 2.8 acres of parkland for the new right-of-way.

•Relocation of park features in the immediate vicinity of the Project site, including Park Road, the Highbridge Parking Area,

and portions of two trails.

Mitigation:

•Upgrade the entrance booth at the Castile Entrance to the park.

•Realign Park Road and construct new, expanded replacement parking.

•Replace a portion of the Mary Jemison Trail and a portion of the

Gorge Trail, including its stone steps and stone walls.


Visual ResourcesImpacts:

•Under Alternative 4, removal of the existing bridge would result in an adverse impact on visual resources in Letchworth State Park.

•Under Alternative 5, two bridges side by side would result in an adverse

impact on visual resources in Letchworth State Park.

Mitigation:

•Align the new bridge to be parallel and close to the existing bridge location

rather than introducing a new bridge elsewhere in the park.

•Use an arch bridge to avoid obstructing views in the gorge.

•Plant new vegetation to selectively screen portions of the new bridge

structure.

•Select an appropriate bridge color: an earth-tone color would blend in more

with the surrounding landscape than other colors.

•Use tinted shotcrete and/or a metal mesh curtain on newly exposed rock

areas of the gorge that must be excavated for the Project, to minimize the

visibility of the excavation.

•Use form liners and coloring on the surfaces of all approach piers and

abutment stems to resemble rock.

•Consult with OPRHP with respect to the re-creation of park features that

must be relocated for construction of the new bridge, such as stone walls

at the Highbridge Parking Area and trailheads for the Mary Jemison and

Gorge Trails.

Wild and Scenic RiversImpact:

•The bridge spans the Genesee River, which is a New York State Scenic River and

protected as a federal Wild and Scenic Study River.

Mitigation:

•Undertake consultation with the National Park Service.

•Implement mitigation commitments for ecology and visual resources impacts.

Construction EffectsImpacts:

•Construction activities would temporarily impact Letchworth State Park for a three-year

construction period.

•The Portageville Entrance, a portion of Park Road, the Highbridge Parking Area, and a

portion of the Gorge Trail and Mary Jemison Trail would be closed to the public for the

construction period. In addition, a portion of the Genesee Valley Greenway Trail would

be closed occasionally.

•Cranes and other large equipment would be visible to park visitors.

•Temporary use of parkland for construction staging.

•Construction noise would be audible in the park, including at times at the Glen Iris Inn

and its associated cottages and at cabins within 1 mile of the construction site.

•Loss of 1.1 acres of shale cliff and talus community, which may provide

suitable habitat for the rare coast creeping moss.

•Potential for temporary disturbance to a pair of bald eagles known to nest in the vicinity

of the Project site, although they are already tolerant of frequent train noise.

Mitigation:

•Provide an upgraded entrance booth at the Castile Entrance to increase capacity, to

mitigate for the lack of access to the park through the Portageville Entrance.

•Use measures during controlled blasting to minimize the size and volume of rocks that

may fall into the Genesee River.

•Use drilled piles rather than driven piles to reduce noise.

•Normal construction work hours 7AM - 5PM, Monday-Friday.

•Use erosion and sediment control measures.

•Use turbidity curtains or other control measures to limit effects on water quality if the

piers of the existing bridge are removed in Alternative 4.

•If dewatering is required, conduct the discharge in accordance with applicable require-

ments.

•Obtain Incidental Take Permit from the U.S. Fish and Wildlife Service for potential

disturbance to bald eagles and conduct construction in accordance with permit require-

ments.

•Implement a Health and Safety Plan to protect workers.

•Implement measures to avoid accidental damage to park features near the construction

zone, such as stone walls. Repair any such damage that occurs accidentally.

•If the area on the east side of the river between Portageville Road and the existing

railroad tracks is used as a staging area, take measures to avoid the potential for impacts

to archaeological resources.

•Repair Park Road and Portageville Road once construction is complete.
