INTRODUCTION Parsons has been retained to document the transportation impacts of Katasa Groupe Developpement’s proposed residential building located at 770 Somerset Street and 13 Lebreton Street. This TIA has been prepared in conformance with the City of Ottawa’s 2017 TIA Guidelines. As such Step 1 was completed to determine the scope of the TIA. Using the TIA Screening Form, it was found that this development meets the Trip Generation Trigger, but does not meet the Location or Safety Trigger. As part of Step 1 City Staff requested that queueing between the proposed access point and the adjacent intersection be examined. The Step 1 TIA Screening Form and Certification Form for TIA PM have been included as Appendix A. 2. DESCRIPTION OF PROPOSED DEVELOPMENT 2.1.
