The City of Ottawa has initiated the pre-consultation/initial planning process for the Environmental Assessment (EA) Study for the proposed Cumberland Transitway Extension. This Information Bulletin has been prepared to provide an update on the work completed to date on the Preliminary and Detailed Design and Environmental Assessment process for the Cumberland Transitway Extension from Trim Road to Frank Kenny Road.
The Cumberland Transitway was planned to address the on-going development needs within the East Urban Community. The Environmental Assessment for the Cumberland Transitway was approved by the Minister of the Environment in 2000 and established the Transitway corridor between the Blackburn Hamlet Bypass and Trim Road. The Millennium Sports Park and a new French Public High School have since been located immediately east of Trim Road and are beyond the extent of the original Transitway EA. A proposed extension of the Cumberland Transitway from Trim Road to Frank Kenny Road needs to be considered in order that the school and sports park can be carefully planned and integrated with the transit system.
A design review was conducted in 2004 to maximize the Transitway integration with the Millennium Sports Park and future potential residential development. Consultation was undertaken with directly affected landowners at that time. Additional EA approval is required for the extension of the Transitway between Trim Road and Frank Kenny Road as illustrated below.
Environmental Assessment Requirements
To complete the environmental assessment for the extension, the project will follow the provincial Transit Project Assessment Process as set out in Ontario Regulation 231/08 – Transit Project Regulation. This regulation provides a framework for focused consultation and the assessment of potential environmental effects and decision-making to be completed within a regulated six-month timeframe.
In May 2010, the Cumberland Transitway Extension was presented to the public at an Open House and included an overview of existing conditions, presented the evaluation of alternative alignments and the preliminary preferred design.
The project also benefits from a Technical Advisory Committee, Public Advisory Committee, and Agency Stakeholders that provide guidance and support through the planning and design processes.
Preliminary Design Update
Since the open house in May, the project team has been refining the preferred alignment which has been summarized in a preliminary design report. The preliminary design relies on both rural and urban cross-sections in the approach and station areas, respectively, and recommends a grade-separated crossing of Trim Road. A grade-separated solution in lieu of an at-grade solution has been recommended based on the following rationale:
- the design is consistent with the major arterial function of Trim Road as it minimizes the number of intersections;
- can accommodate development scenarios within the Transportation Master Plan horizon to 2031;
- property requirements can be acquired concurrently with future development proposals within the area;
- Longer lifecycle can accommodate transit system retrofits beyond the year 2031; and
- Optimizes long term safety of Trim Road operation between Millennium Drive and Montmere Avenue.
Some refinements during the preliminary design process have included:
- Inclusion of a 3.0 m parallel multi-use pathway located to the north of the Transitway alignment east of Trim Road crossing under the Trim Road overpass;
- Details for Millennium and Frank Kenny Stations;
- Preliminary designs for the Transitway underpass structure to cross Trim Road; and
- A drainage solution for both urban (Millennium/Trim) and rural sections of the Transitway.
The preliminary design report can be viewed by following the link provided or by contacting the City Project Manager. Preliminary design drawings are included.
Schedule and Next Steps
A public open house will be scheduled for spring 2011 at which time the impact assessment of the preferred design will be presented for public comments. An Environmental Project Report (EPR) will be completed and made available for review following this open house.
