2.3 Background Development and Transportation Projects . The No-Build 

 network will be based on posC-CANA traffic networks developed for 

 the CANA project. These networks are currently being reviewed by 

 Vanasse Hangen Brustlin, Inc. for the City of Boston. These 

 networks, as revised and accepted by the City of Boston, will form 

 the basis of the 1991 No-build analysis. The current review will 

 assure that the networks reflect the impact of all development and 

 roadway improvements planned in Che area. 



2.4 Evaluation of Transportation Impac ts. New crips expected co be 

 created by the proposed developmenc will be added to demands 

 expected to be carried by the poflC-CANA transportation 

 infrastructure. AM and PM peak hour and daily increases will be 

 developed and analyted for all travel modes, as described below: 



1. Traffic Impacts - Volume/capacity ratio (V/C), Available 

 Reserve Capacity (ARC), and Level of Service (LOS) calculations 

 at key study area intersections. 



2. Parking Impacts - Increased parking demand will be compared 

 with existing and projected available supply to identify any 

 potential deficiencies. The analysis will discuss long term 

 vs. short term parking needs, provisions for carpoola and 

 vanpools , and Che possible location of parking under the 

 Charlastown Bridge. 



3. Public Transportaclon - Increased ridership and its impacts on 

 the area's rapid transit, cominucer rail, local and express bus, 

 and water transport services will be identified. The possible 

 provision of docking facilities for water transport will be 

 investigated. 



A. Pedestrian Impacts - An evaluation of pedestrian volumes on 

 pathways co the site will be conducted. Pedestrian pathways 

 and linkages to other major area generators, MBTA stations, 

 adjacent neighborhoods and Paul Revere Park will be Identified, 

 including the Freedom Trail and access to and from the 

 Charlescown Bridge. 



5. Loading/3erviee/0n-slce Circulation - Truck and service vehicle 

 traffic CO the site will be estimated. On-slta circulation 

 patterns and parking access will also be described. 

 Performance of the proposed loading and service configuration 

 will be evaluated in cerms of the demands identified. The 

 adequacy of the intersection of Charles River Avenue and Water 

 Street, which will serve as Che site driveway, will also be 

 evaluated.
