Brian Coburn Extension / Cumberland Transitway Westerly Alternate Corridor EA Study

Project Status: 

Project Overview

The Environmental Assessment (EA) for the Blackburn Hamlet Bypass Extension (BHBPE) was completed and approved in 1999. The EA for the Cumberland Transitway was also undertaken at the same time as the BHBPE EA due to their proximity, particularly for the section from the Bypass to Mer Bleue Road (Figure 1).

Portions of the BHBPE (now called Brian Coburn Boulevard) have been built from Navan Road to east of Mer Bleue Road.  A recent geotechnical analysis concluded that the soil conditions in the vicinity of Navan Road to BHBPE section are very poor and the roadway would require considerably more funds to construct than previously estimated. The City is in search of a more cost-effective alternate corridor. Consideration must be given to any consequential changes to the adjacent future Cumberland Transitway.

Study Area

The EA study limits will extend from Blair Road to Brian Coburn Boulevard and south to Anderson/Renaud Road to allow for a larger range of alternatives to be examined.

Study Process

The study is being conducted in accordance with Ontario's EA Act, fulfilling the requirements of the Municipal Class EA process for Schedule C projects. The City must consider alternatives for the project, undertake public and agency consultation, assess the potential environmental impacts of the Recommended Plan and identify measures to mitigate any such impacts.

The study will also address potential implications of federal and National Capital Commission (NCC) properties and the need for federal approvals to implement the project.

As part of the study process, an Environmental Study Report (ESR) will be prepared for public review.

Get involved!

You are encouraged to participate in the study by attending consultation events or by directly contacting the study team with information, comments or questions. Updated project information will be posted periodically on the study website.

The study will also have the benefit of input from agency, business and public consultation groups that will meet at key points during the study.

Two open houses (minimum) will be scheduled throughout the study as an opportunity for interested persons to learn about the study and provide input. Notifications for the open house will be provided through local newspapers, e-mails to the study mailing list and postings on the website.

The City of Ottawa has initiated the Environmental Assessment (EA) study to develop an alternate plan for both the Brian Coburn Boulevard Extension and the Cumberland Transitway west of Navan Road. A recent geotechnical analysis concluded that the soil conditions in the area are very poor and it will be more costly than previously estimated to implement the previously approved 1999 EA Study Recommended Plans. As such, the City is in search of a more cost-effective solution.

The study is being undertaken in accordance with Schedule C of the Municipal Class EA, which is an approved process under the Ontario EA Act. The EA process will involve developing, assessing and evaluating alternatives, leading to a Recommended Plan.

This Open House will provide information on:

  • Study process and existing conditions
  • Preliminary corridor options

Your participation is an important component of the study and interested persons are invited to provide comments throughout the EA process. Any comments received will be collected under the EA Act and with the exception of personal information, will become part of the public record.

What We Heard from Public Meeting #1

Will there be a presentation in French for the second Open House?
Yes, subsequent Open House presentations will include fully bilingual presentations.

Will the material presented for the second Open House have larger graphics and presentation?  
Yes, subsequent Open House material and presentations will use larger and clearer graphics and images.

Noise and vibration impacts need to be considered. How will this be done?  
Once the preferred Option has been selected, noise and vibration impacts will be reviewed. Noise sensitive areas, such as backyard living areas among others, will be identified. Changes in noise and vibration levels will be assessed and recommendations made based on the Ministry of the Environment and Climate Change and City of Ottawa Environmental Noise Control Guidelines.

Will property values decrease as a result of the bus rapid transit (BRT) and construction? 
As the construction will be occurring for a short period, it would not affect property value.

The traffic assessment needs to consider both existing and potential future traffic volumes on all area roads especially where congestion is already occurring. How will this be considered in the study?
The traffic model produced by the City and the Needs Assessment considered both existing and future travel demand. Future travel demand is based on the City’s Official Plan projections for population and employment to the planning horizon of 2031.

Will there be a new Option 7 considered along Renaud Road?
A new Option 7 will be developed and included in the evaluation. Option 7 would include extending and widening Renaud Road to 4 lanes and BRT along Renaud Road. See figure below.

Brian Coburn study area

What is the status of the Innes / Walkley / Hunt Club connection (IWHC)?
The IWHC connection will address growth and relieve congestion on Innes Rd. between Blair Road and Highway 417 as well as provide a connection between Orleans, Walkley and the Hunt Club area. Construction of this connection is identified beyond 2031 as per the City’s Transportation Master Plan (TMP).

Will Chapel Hill residents continue to have full access to Navan Road south of Brian Coburn Boulevard as well as the new Park and Ride?
The proposed cul de sac of Navan Road near Brian Coburn Boulevard in many of the Options shown will prevent access. The study team is refining the Options to avoid and minimize roadway closures. This is to ensure effective connectivity and access between communities and that other possible trip origins and destinations are maintained.

Will High-occupancy vehicle (HOV) lanes be included or considered as part of this study?
The study team will be considering HOV lanes as part of the interim and/or ultimate solution.

Why are BRT stops being considered along the Blackburn Hamlet Bypass?  
The BRT stops along the Blackburn Hamlet Bypass are currently identified in the City’s Transportation Master Plan. Once the preferred Option has been selected, transit stop locations will be identified based on ridership.

Will community impacts be given consideration as part of this study, including cut-through traffic, encroachment, noise and access? 
All of these factors will be taken into consideration in the evaluation of the different Options.

Will cycling and pedestrian facilities and connections be considered in the design of the preferred alternative?
Yes. The functional design of the preferred Option will include cycling and pedestrian facilities and connections as per City policy.
