Hunt Club to Southeast Transitway Pathway EA
The goal of this meeting is to:
- Describe the Environmental Assessment (EA) process
- Present a summary of existing conditions information
- Indicate the alternatives considered in the study
- Describe the Evaluation of Alternatives
- Present the Recommended Plan and mitigation measures
- Identify steps to complete the project
- Obtain your comments
The Hunt Club Community to Southeast Transitway Pathway EA was initiated to examine how to better connect residents with rapid transit, neighbouring communities and local commercial areas. This project has been identified in the City’s Official Plan – Hunt Club Secondary Plan (2003), the Ottawa Cycling Plan (2008) and the Ottawa Pedestrian Plan (2009).
In 2008, City Council mandated staff to complete an Environmental Assessment (EA) to determine the pedestrian connectivity solution between the Hunt Club Community and the South Keys and Greenboro rapid transit stations. This study will ultimately satisfy the requirements outlined in the Class EA, which is required under the Planning Act. The main objective of this study will be to gain approval for a recommended future connection linking the Hunt Club Community with the Sawmill Creek Constructed Wetlands and the Southeast Transitway. Following the completion of this EA, the project will be carried forward to the detailed design stage prior to implementation.
The study area extends from Plante Drive / Cahill Drive West / McCarthy Road to Bank Street. The North-South boundaries are the CN Rail line to the north and Hunt Club Road to the south. The Airport Parkway and the Sawmill Creek Constructed Wetland (SCCW) are located centrally within the study area. East of the SCCW are the north-south rail corridor and Southeast Transitway including two major stations (Greenboro and South Keys). The lands east of these transit corridors include the South Keys Shopping Centre.

Environmental Assessment Process
This project is being undertaken as a Schedule “C”, Class EA in accordance with the Municipal Class Environmental Assessment Study, 2007, which is available at the Resource Table. This study will also be harmonized to satisfy the requirements of the Canadian Environmental Assessment Act, if triggered by this project.
There is opportunity at any time during the Environmental Assessment process for interested persons to provide comments and review outstanding issues. If after participating in this project, and at the conclusion of the study, you still have serious environmental concerns, you have the right to request the Minister of the Environment to reclassify the project through a Part II order (or “bump-up”) to an Individual Environmental Assessment.

Study Design Update
A review of the study schedule was considered by the study team following the substantial feedback from the public at Public Open House No. 1, reviewing additional project related information related to existing conditions and previous public feedback from the Sawmill Creek Constructed Wetland design consultation, and undertaking preliminary works in regard to the evaluation exercise.
It was determined that a revised schedule was the appropriate course of action as a method of removing redundancy within the process for this particular project, ensuring that the study’s overall time frame was adhered to, and meeting process requirements.
In summary, the revised project schedule will allow the project to be completed and presented to City Council early in 2010.
Summary of Existing Conditions Information
Limited due to the amount of on-going development in the area. Considered to have been transformed from a natural condition by mid 1980s. Small isolated woodlot immediately north of CN rail corridor (dominated by White cedar).
Natural topography is generally flat. Glacial till typically overlie bedrock. Leda clay overlies till within study area. SCCW excavated to several metres below table land.
Low density residential, South Keys Shopping Centre, new developments at 40 Mountain Cres. and 2200 Bank Street. The OP designates the Airport Parkway as a scenic entry route.
Watermain follows Airport Parkway through the study area. Sawmill Creek Constructed Wetland (SCCW) provides quantity and quality control of discharge to Sawmill Creek.
Archaeological and Heritage
A single site has been registered. Portions of site have archaeological potential - Aboriginal and Euro-Canadian archaeological sites.
No fish habitat was observed in any of the storm pond cells, however components of the area can support fish habitat.
Underpass at O-Train corridor in poor condition with numerous efflorescence stained cracks on soffit and extensive delamination on the abutments (single span rigid frame).
Need for a Pedestrian Crossing
The need for a pathway connection was confirmed based predominantly on safety issues associated with an existing travel demand line. An informal unsigned route between the Hunt Club Community and South Keys Station was confirmed and a review of travel demand and study area transportation layout information indicated that a new pathway connection is needed. It should also be noted that a pedestrian connection has been included in City Plans (Ottawa Cycling Plan, Ottawa Pedestrian Plan and the Official Plan - Hunt Club Secondary Plan).
Hunt Club Secondary Plan
Ottawa Cycling Plan (OCP)
Based on existing conditions information and general input provided by the study team, public, and agencies, the preliminary list of alternative alignments presented at the first Public Open House was refined.
Evaluation of Alternative Alignments
A set of criteria was developed upon which to evaluate the alignment alternatives based on study team, public, and agency input. A long list of criteria was initially developed (included in the Evaluation Report). For the purposes of determining a preferred alternative, only the evaluation criteria, which result in measurable differences between the alternatives, were carried forward into the quantitative evaluation. These criteria are shown below. (NOTE: Alternative 8 coarse screened for safety reasons – i.e. proximity of pathway to adjacent rail track and unprotected use of Transitway boulevard.)
Short List of Evaluation Criteria
- Travel Distance to Rapid Transit Station
- Ability to deter pedestrians/cyclists from crossing the Airport Parkway at an undefined crossing location
- Ability for alternative to allow for casual surveillance
- Pedestrian/Cyclist safety associated with CPTED principles
- Visual intrusion
- Potential removal of vegetation
- Residential catchment
- Commercial/industrial catchment
Land Use and Property
- Easement on CN Rail lands required
- Easement on NCC property required

Airport Parkway Crossing Alternatives
Any pathway connecting the Hunt Club community with the Southeast Transitway will require crossing of the Airport Parkway. A number of alternatives exist to implement a crossing of the Airport Parkway:
Evaluation of Airport Parkway Crossing Alternatives
Alternative C1 (At Grade Crossing) NOT CARRIED
Airport Parkway / Hunt Club Road queuing impact; driver / pedestrian / cyclist conflict; Airport Parkway form and function impact; pedestrian / cycling travel delay / potential for disobedience
Alternative C2 (Pathway over Airport Parkway) CARRIED
Separates pedestrian / cycling crossing traffic from vehicles; maximizes casual surveillance; reduced potential for creating entrapment locations; no modifications to Airport Parkway
Alternative C3 (Airport Parkway over Pathway) NOT CARRIED
Significant adjustment to the vertical profile of the roadway; unfavourable from Crime Prevention Through Environmental Design (CPTED) perspective - entrapment areas, vandalism, natural lighting
Alternative C4 (Pathway under Airport Parkway) NOT CARRIED
Presents challenges from a CPTED perspective - entrapment areas, vandalism, natural lighting ability; waterproofing requirement; potential Impact on the water distribution main under Airport Parkway
Alternative C5 (Airport Parkway under Pathway) NOT CARRIED
Similar to option C3, this option is not recommended as it presents potentially significant investment to modify the Airport Parkway profile.
Alternative C6 (Split grade over Pathway) NOT CARRIED
Similar to the discussion regarding option C4, this option is not recommended to be carried forward.
Alternative C7 (Split grade over Airport Parkway) NOT CARRIED
Similar to the discussion regarding option C2, this option presents a number of similar benefits, however the effort of adjusting the grade of the Airport Parkway has a high potential for significant modifications.
Multi-Use Pathway Cross-Section
The Ottawa Cycling Plan (OCP) includes the preferred multi-use pathway cross-sections. In general, a 6.0 m cross-section is required with a 3.0 m asphalt pathway with 1.5m of adjacent cleared areas along both sides of the pathway. A vertical clearance zone of 3.0 m is preferred.
- A preliminary design was undertaken for the Technically Preferred Alternative as per the evaluation. This design was cross-reviewed with public, study team, and agency input and refinements to this initial design were made to form the Recommended Plan.
The following presents a description of the plan:
- Pathway between Cahill Drive West and South Keys Station
- Alignment designed to minimize travel distance for pedestrians while maintaining appropriate accessibility requirements.
- Post-tensioned concrete bridge type was proposed at this stage of the project as per input from bridge design staff related to feasibility, cost, aesthetics, potential to accommodate flexible design of the future Airport Parkway, and casual surveillance, and as such should be carried forward to the next stage for further investigation. Specific detailing of bridge features (i.e. facade, lighting, edge protection materials/design) will be undertaken as part of the detailed design stage.
- Lighting to ensure both visibility for users and casual surveillance
- 5.5 m height clearance over Airport Parkway to ensure appropriate separation from the roadway surface
- Bicycle parking within the area of the Sawmill Creek Constructed Wetlands (SCCW) and in the vicinity of South Keys Station will be incorporated.
- Existing railway underpass will be refurbished to accommodate alignment until the ultimate form of South Keys Station is in place.
- Connection to maintain existing pathway connectivity in the SCCW will be implemented
- Landscaping along pathway bridge approaches
- Screen plantings to mitigate visual intrusion
- Preliminary cost estimate indicates anticipated cost of $4.2 million for the pathway connection including the new bridge, approach embankments, pathway alignment segments, and South Keys connection. The following boards present illustrations and drawings of the Recommended Plan followed by photographs of example pedestrian bridges.
Example Pedestrian Bridge Elements to Consider (Photographs by Others)
The images below provide examples of existing or proposed pedestrian bridges in other locations. Each possess bridge features which could potentially be considered at the detailed design stage of the Airport Parkway crossing component in an effort to maximize the bridge as a “gateway” / “scenic entry” to the City.
