5.8 Site Layout and Circulation

The Rochester Station Project shall promote ease of transfer between transportation modes and circulation throughout its exterior site, but must also segregate different uses for safety reasons. Intercity and potential future city bus operations cannot share access or space with cars and shuttles. Drop off/pickup for passengers must be separated from general parking and shall share access with both short term parking and taxi/shuttle bus movements. The Design‐Builder shall ensure pedestrians are protected and separated from vehicular movements wherever possible.




It is desirable to promote a visual presence of the new station along the North Clinton frontage in order to create a visual connection with downtown Rochester along that street to the south. To ensure the shortest possible passenger travel distance, the station building should be sited as close as possible to the center line of tracks, while adhering to the twenty‐five foot minimum clearance from the centerline of the nearest track bed. The goal of a ‘seamless journey’ through the station building to the boarding area shall be achieved with this configuration. There are other mandates that shall impact the location of the station building and other site features including, but not limited to:

A. Replacement of the existing low‐level platform with an ADA compliant high level center island platform for passenger access to Amtrak service to Empire, Maple Leaf, and Lake Shore Corridors.

B. Minimize customer travel distance between station functions and the platform. C. Consolidation of traffic movements’ onto the Central Avenue frontage in Phase One to

eliminate sight distance conflicts at Joseph Avenue and North Clinton Avenue. D. Segregation of baggage and passenger traffic. E. Provision of ramps to accommodate baggage movements in lieu of elevators. F. The new station building must maintain a minimum of twenty‐five feet clear envelope

from the centerline of the southernmost track with additional 10’ setback recommended wherever possible to minimize flagging and lower construction costs for the building.

G. Provide ADA accessible path connecting all site and program elements. H. Provide a covered path to transport baggage from the Baggage Work Area to the exterior

baggage ramp and into the Concourse without exposing baggage to weather. I. Provide a covered path to transport baggage from the Concourse to the Platform without

exposing baggage to weather. J. Provide a covered area for passengers to board Trailways buses. Since wheelchair

boarding is at the very rear of the bus, the bus canopy extends to cover the entire length of the buses.

K. Install large skylight units in both the baggage and bus boarding canopies to allow natural light into these large shaded areas.

L. Allow for the installation of bicycle share facilities. M. Widen North Clinton and Joseph Avenues to provide street side bus stops for RGRTA bus

routes. Provide bus shelters at these layovers for waiting passengers. N. Provide queue space for taxis, university shuttle vans, and other paratransit services O. Allow for passenger drop off and pick up at the Station entry, and provide short‐term

parking near the Station entry.

The site layout shall incorporate softscape wherever possible, eliminating any unnecessary paving in accordance with the City of Rochester’s Project Green policy, especially at the North Clinton Avenue frontage. North Clinton has been identified by the City as one of the proposed “Green Corridors” that shall feature integrated bicycle and pedestrian circulation. The landscape shall include trees along the street line and along pedestrian paths to create an urban environment that is pleasant and friendly for bicyclists and pedestrians. The Design‐Builder shall balance the requirements of both the City of Rochester and Amtrak security




concerns, including small trees compatible with an urban setting that do not allow for hiding places. Landscaped islands shall be incorporated in the parking areas to soften the hardscape. LED site lighting shall be supplemented with additional pedestrian level lighting along major circulation routes. The Design‐Builder shall provide life‐cycle cost analysis for LED site lighting or other proposed substitute. Loading dock and trash and recycling storage shall be screened from public view.

Exterior to the station building, a Kiss and Ride Drop‐Off location, taxi stand, and short‐term parking are sited along the Central Avenue frontage. For ease of arrival and departure, the pick‐up and drop‐off lanes are designed at a minimum of twelve feet wide. Similarly, the taxi berths are minimally twenty feet in length with an additional five feet for maneuvering. Sidewalks throughout the site shall be a minimum of 8 feet wide, and crosswalks shall receive a thermoplastic decorative treatment. The Design‐Builder shall provide speed tables at major pedestrian crossings for both traffic calming and for ease of accessible travel with bollards for pedestrian safety.

5.9 Other Site Components

A place for garbage storage and retrieval shall be provided onsite concealed and screened from public view. Additional station maintenance items, such as snow plow, ice melt, and additional baggage floats and carts shall be accommodated with a minimum of three hundred square feet of covered exterior Amtrak storage space per Amtrak Functional Space Requirements, issued on 12/30/2012.

In order to further sustainable initiatives, a Construction and Building Site Waste Management Plan shall be in place to ensure 50% recycling and/or salvaging of existing material. Throughout the site, low maintenance landscaping shall be integrated to minimize impervious surfaces. The Design‐Builder shall grade areas away from structures to prevent ponding, while mitigating the flow of runoff over impervious surfaces.

SECTION 6. GEOTECHNICAL REQUIREMENTS

The Design‐Builder shall be responsible for geotechnical design and construction of all permanent and temporary structures, including assessing available information, geotechnical analysis and reporting, geotechnical instrumentation and monitoring, and protection of existing infrastructure, structures and utilities in accordance with the requirements of the Contract Documents.
