June 2014 Former CFB Rockcliffe Redevelopment Community Transportation Study Prepared by: 12 February 2015 ERRATA SHEET The land use statistics associated with the Development Concept Plan for the Former CFB Rockcliffe Redevelopment are continually being refined as part of the on-going planning process. During the Summer 2014, the Plan was modified slightly from that used as the basis for the ensuing Community Transportation Study (dated 27 June 2014) resulting in approximate 40 additional residential units and 40 additional retail-related jobs. As a result of this land use change, the net change in two-way, peak hour vehicle trips to/from the site is noted to be an increase of approximately 60 veh/h, which is considered very minor in scale in comparison to the total projected generation of approximately 2,000 veh/h two-way. This small discrepancy in vehicle trip generation would have no bearing on the report’s finding or recommendations. A subsequent update to the Development Concept Plan was received in January 2015 reflecting very minor adjustments to the proposed land use. In September 2014, the National Capital Commission announced the renaming of the Rockcliffe Parkway to the Sir George-Étienne Cartier Parkway (Promenade Sir George-Étienne Cartier). This name change has not been reflected within the current version of the report. In December 2014, the City of Ottawa requested that the CTS include commentary/analyses related to multi-modal level of service as outlined within the 2013 update of the Transportation Master Plan, Ottawa Cycling Plan and Ottawa Pedestrian Plan. The draft analysis related to this most recent City request is included herein as an Addendum No. 1 to the CTS, and consideration will be given to incorporating it within the main body of the report as part of a future update. The multi-modal level of service analysis emphasizes the importance of providing high quality pedestrian, cycling and transit facilities serving the site in support of the sustainable transportation vision. Provision of needed facilities and the proposed street and intersection designs will be addressed from this perspective. { Former CFB Rockcliffe Redevelopment COMMUNITY TRANSPORTATION STUDY prepared for: Canada Lands Company Limited 30 Metcalfe Street Suite 601 Ottawa, ON K1P 5L4 prepared by: 1223 Michael Street Suite 100 Ottawa, ON K1J 7T2 27 June 2014 TO3138TOA00 Community Transportation Study Former CFB Rockcliffe Redevelopment June 2014 TABLE OF CONTENTS 1.
