The 2013 TMP PROPOSED Road Network PLAN
The 2013 TMP PROPOSED Road Network PLAN
Jan 2013: The most significant result from the 2013 Transportation Master Plan (TMP) update was that 2 of the inside the greenbelt road projects which received significant opposition (Alta Vista Corridor and Prince of Wales Dr widening) were significantly delayed by 10-15 years to beyond the 2031 horizon.
Jan 2016 Update: Since the 2013 plan was initially approved, many of the roads proposed in the first phase (2014-2019) were further delayed and pushed off into the 2nd post 2020 phase. The reason for this is that new roads are to be primarily funded from development charges collected from new development and the pace of such development has been slowing compared to the projections back in 2013.
This information was revealed in a Jan 2016 Ottawa Citizen article which goes on to list the following road projects as those being delayed:
Airport Parkway widening north of Hunt Club road
Building a new four-lane road between Orléans Boulevard and Navan Road
Widening Mer Bleue Road from two to four lanes between Brian Coburn Boulevard and Renaud Road
Realigning Palladium Drive in the vicinity of Huntmar Road to a new north-south arterial
Building a new underpass on Earl Grey Drive where it meets Terry Fox Drive
These projects are all listed in the 2013 plan below, both on the bar chart as projects depicted by the green bars (Phase 1) and in the table following that.
Details of the Original 2013 Plan
The 2013 TMP proposes 724M$ of road expansions (widenings and new roads) during the period from 2014 to 2031. The 724m$ was arrived at by assuming 85% of the funding would come from development charges and the remaining amount from property taxes. The City made a best guess as to the $ value of development charges that can be collected over this period as well as the $ value of property taxes available in annual budgets for funding new roads.
The proposed new road projects are illustrated on the map below (click on the map for an enlarged view)
This proposed road network was arrived at by scoring each project with a score of 1-4 according to 5 criteria"
- provides access to new development
- manages congestion
- cost effectiveness
- addresses network gaps
- supports non-motorized traffic and transit
The scores were summed to a point total and then the roads were sorted in order and added to the plan until the 724m$ was used up. The following chart shows the roads that made the cut and the extent to which they 'used up' the 724m$ of available money. Clicking on the chart will provide a larger image for better viewing.
An alternative view of this same information in chart form, providing a more detailed description of the road projects and their individual cost estimates, is provided below.
Finally, members of council asked that a more detailed ranking be taken for roads that were just outside the affordable window (the ones in light blue on the right in the diagram above) so that if any additional funds might become available (or cost savings) that would allow for more expansions then the next most desired projects would be captured in this plan.
To accomplish this, the same technique of ranking against the same 5 criteria as above was employed except this time the scores were assigned on a basis of 1-10. The results of that ranking are summarized in the chart below. The 2 more controversial road projects, the Alta Vista Transportation Corridor (south section) and the Prince of Wales Drive (north section) widening ranked 5th and 7th 'below the line' in this chart. The Alta Vista Transportation Corridor northern section with a new bridge across the Rideau River ranked significantly lower yet and could be expected to be delayed considerably beyond 2031.
The detailed background analysis document (2013 TMP Roads Anlaysis, 6.5MB) from which the above information was copied provides an analysis of expected growth in congestion across the City, detailed costing for each of the road projects, and the scoring used to rank the projects.
