CORRIDORS TO BE ELIMINATED FROM FURTHER CONSIDERATION 47 Hudson River Valley Greenway Link Task 4 Research INTRODUCTION The primary goal of the Hudson River Valley Greenway Link project is to align a north/south corridor linking the Old Croton Aqueduct (OCA) Trail in Yonkers with the Hudson River Greenway along the Hudson River at Dyckman Street in Upper Manhattan. In order to begin the process of identifying a preferred corridor, a number of potential alignments have been identified as part of Task 4. These alignments are described herein and will be analyzed in further detail in Task 6. The goals and objectives outlined in the Task 3 deliverable state a desire for a route that provides for both recreational as well as utilitarian trips. The alternatives described for further analysis are defined to emphasize the link’s function as a greenway, connecting to nature and the waterfront. The project will also define spurs and connectors from the greenway route that will provide connections to other desired destination points such as parks, commercial centers and corridors, transportation hubs, and institutions. Below is a list of the criteria that were considered in selecting the alternatives to be analyzed in further detail in Task 6. • Physical proximity to the waterfront • Visual access to the waterfront • Proximity/connectivity to parks, and other recreational areas • Proximity to nature • Traffic volumes • Roadway width • Roadway capacity • Pavement conditions • Steepness/topography • Directness • On‐street parking • Surrounding land use • Proximity/connectivity to employment centers; individual large employers or concentrations of employment. • Proximity/connectivity to commercial facilities ‐ Including shopping centers, malls, large retailers, etc. • Proximity/connectivity to mode transfer – Major points of mode transfer such as transit hubs, railroad stations, connections to other bike routes. • Proximity/connectivity to educational facilities. 1 Hudson River Valley Greenway Link Task 4 Research • Area demographics ‐ Population density and age, household size and type (single family, multifamily). • Appropriateness for both pedestrians and bicyclists Sources of data and information used to determine a segment’s suitability as a greenway route include: • existing traffic and operational data provided to the project team, • field observations, • public feedback and information received at two workshops, • feedback and information received from the Technical Advisory and Steering committees. For the purpose of this analysis, corridors have been divided into segments based upon their characteristics. Figures 1 and 2 show an overview of all the corridor segments, each of which is labeled numerically and described in an accompanying call‐out. The segments have been grouped together to form the potential greenway corridors that will be studied in further detail. These corridor alignments are outlined and described below. 2 9.
