Introduction In this update of its Transportation Master Plan (TMP), the City of Ottawa is taking a new approach to the planning of its transportation infrastructure. In recognition of limitations to funding, environmental pressures, and changing traveller preferences, the city is making transit the focus of its planning efforts. However, improvements to the road network will remain an important element of the TMP in support of its primary objectives. This is largely because, in addition to auto traffic, local transit vehicles, bicyclists and pedestrians all use road rights of way. As such, the road network is still an integral component of an efficient, equitable and sustainable transportation system. To this end, this report recommends improvements to Ottawa’s road network over the 18-year horizon of the TMP. This will be accomplished by building on the 2008 TMP and on the updated needs and opportunities assessment conducted earlier in this study (published under separate cover). Specifically, this report outlines the details on when and why certain roads projects are to be built, and how they fit within the City’s affordability framework. Analysis in this report was carried out in accordance with Phases 1 and 2 of the Municipal Class EA process, which deal with project need and justification and evaluation of alternative solutions. While a detailed environmental review was not undertaken for each individual project, an understanding of local environmental assets was developed to assess the relative merit of the various transportation corridors and alternatives and corresponding road improvements, where required. Justification and costing for all new road links and an assessment of the ease of implementation is provided. 1.1 Objectives The primary objective of this report is to provide the reader with a review of the analysis completed towards developing a recommended road network for 2031. To accomplish this, the report will: Identify road improvements required by 2031; Provide an estimate of the costs for these projects; Determine the priority of each project; and Develop a package of affordable projects for implementation, in light of financial constraints. 1.2 Approach Given that the 2013 and 2008 TMP updates share a common horizon year (2031), the approach to the analysis in this report is to use the 2008 TMP network as a base from which projects are added or subtracted. However, this is not to say that the findings will be identical to the last TMP. There have been several changes in the five years since the last TMP that will impact the recommendations of this report. Notably: SEPTEMBER 2013 1 IBI GROUP FINAL DRAFT: ROAD NETWORK DEVELOPMENT REPORT THE CITY OF OTTAWA Several projects prescribed in the 2008 TMP have been built; Environmental Assessments have been completed that may have proposed different solutions to what was proposed in the last TMP; There have been roadways proposed as part of new community design plans and other studies; The TRANS travel demand model has been re-calibrated to the 2011 OD survey; This TMP will design roads to the demand observed during the 2031 2.5 hour peak period, whereas the 2008 TMP designed roads to the 2031 peak hour; and The recommendations of this TMP will have to fit within the City’s affordability envelope, whereas past iterations were not (formally) financially constrained. In light of these considerations, the 2008 TMP network will serve as the starting point for quantitative analysis. The network will then be modified in light of changes and progress since 2008. Needs will be assessed primarily at the screenline level during the AM peak period, but consideration will also be given to high growth areas or locations in the network that are known to be congested outside of the peak. The projects identified from this assessment will then be costed and prioritized in consideration of various criteria. Finally, a set of “affordable” projects will be identified for implementation between the present day and 2031. This process
