Geomorph and Geotechnical Existing Conditions • Reaches 3, 4, and 5 • Located within Local Study Area East Don Trail Environment Assessment
Stream Systems Understanding – Reach 3 Key Features: •Significant valley wall contacts throughout reach along outside bend of swooping meanders. •Channel primarily natural condition with floodplain access into mature valleyland • Minimal channel alteration, only local areas of bank / rip rap protection. •Sanitary sewer within valley system. •One location where trail may extend along top of valley. East Don Trail Environment Assessment
Stream Systems Understanding – Reach 4 Key Features: •Wide valley setting with meander contacts along both slopes; •Average W:D – 35m:1.5m – slightly wider than R3; •Localized areas of erosion / slope protection; •Active channel migration and bend extension where unmitigated; •Overtopping / floodplain access under moderate flow conditions. East Don Trail Environment Assessment
Stream Systems Understanding – Reach 5 Key Features: •Confined valley setting with low amplitude meanders; •Average W:D – 30m:2m – slightly narrower and deeper than R3; •Recent channel and slope engineering to facilitate maint. route; 7 8 •Channel generally stable condition; •Overtopping / floodplain access under moderate flow conditions.

Geomorph and Geotechnical Existing Conditions Questions? East Don Trail Environment Assessment
Alternative Methods Recap: Process to this point: • Problem/Opportunity Statement Introduction and Identify Problem/opportunity • Project Objectives Nov. 2012 - May 2013 • Alternatives To Existing Conditions Alternatives To and Evaluation • Provide Multi Use Trail Connection • Alternative Trail Alignments Alternatives Methods May - Sept. Today 2013 Evaluate Alternatives • Draft Evaluation Criteria Methods/Trail Alignments Preferred Alternative Oct. 2013 - Jan. 2014 Refine Preferred Alternative Feb. – June Environmental Study Report 2014 East Don Trail Environment Assessment
Problem/ Opportunity Statement A significant gap in the multi-use trail network exists within the East Don Corridor between Existing East Don Trail (East of Wynford Heights Crescent), Gatineau Corridor Trail (at approximately Bermondsey Rd), and the Don Trail System. The East Don Trail will fill this existing gap in the trail network thus creating a continuous connected trail network. East Don Trail Environment Assessment
Project Objectives Connections • To provide a key connection route linking local and inter-regional trail systems. Public Safety • To provide a safe way for a broad spectrum of users to access the valley system. • To provide safe off road options (where possible) for cycling and recreational use. • To investigate options to accommodate emergency response, City and utility maintenance vehicles/activities. Natural Environment • To assist in the management of informal trails by providing a single focused multi-use trail within the East Don Corridor. • To be respectful of the natural environment through the alignment, design, and construction of the trail by aiming to avoid, prevent, or minimize negative impacts. • To increase access for a range of users to discover and appreciate natural areas within the City. East Don Trail Environment Assessment
Project Objectives Recreation • To create trail and outdoor recreational opportunities for a variety of users. • To provide trail and outdoor recreational opportunities for neighboring communities. Transportation • To function as a safe travel route to everyday places and amenities. Supports Other Initiatives • To coordinate with other planning initiatives in the area allowing for future integration of the multi-use trail. (e.g. Eglinton Cross-town LRT). East Don Trail Environment Assessment
Alternatives Alternatives To • These are alternatives to the undertaking and are functionally different ways of approaching and dealing with the problem or opportunity. • Preferred alternative to: Provide Multi Use Trail Connection Alternative Methods • These are alternative methods of carrying out the undertaking and are different ways of doing the same activity. • For the purpose of this project termed: Alternative Trail Alignments. East Don Trail Environment Assessment
Alternative Trail Alignments • Different trail alignment options. • High level – details will be addressed as part of the refinement of the preferred alignment. – For example, will determine if we need to cross the river but will not assess bridge length or load capacity. • Will undergo evaluation to determine the preferred alignment (next CLC meeting). • Broken down into 3 Areas, these areas have been determined based on infrastructure and property challenges and river reach processes.

Alternative Trail Alignments Areas Area 1 2 trail alignment options: • Forest Trail A • Forest Trail B Area 2 9 trail alignment options: • Road Link A • River Walk A • Rail Trail A • Road Link B • River Walk B • Rail Trail B • Road Link C • River Walk C • Rail Trail C Area 3 3 trail alignment options: • Access Route A • Access Route B • Access Route C East Don Trail Environment Assessment
Alternative Trail Alignments Area 1 Alternatives: Forest Trail A Forest Trail B • Northern extent of study area • Connects with existing East Don Trail • Potential ESA • Adjacent Wynford Concord, Victoria Village Alternative Trail Alignments Existing Trail Bridge Crossing Potential Slope Stability Issues East Don Trail Environment Assessment
Alternative Trail Alignments Area 1: Issues and Challenges 1 2 1. Potential River Crossing Location 2. Crossing Under Rail Line East Don Trail Environment Assessment
Alternative Trail Alignments Area 1: Issues and Challenges 3 3. Large Erosion Scar 4 4. Potential rail line tunnel location East Don Trail Environment Assessment
Alternative Trail Alignments Area 1: Issues and Challenges 5. Potential River Crossing Location 5 6 6. Potential Eglinton Crossing East Don Trail Environment Assessment
Alternative Trail Alignments Area 1: Forest Trail A Key Points • 6 bridges • Erosion remediation works not required • Allows connections to be made into Victoria Village • ~1.6km East Don Trail Environment Assessment
Alternative Trail Alignments Area 1: Forest Trail B Key Points • 4 bridges • Erosion remediation works would be required • Does not allow for connections to be made into Victoria Village Community • ~1.6km East Don Trail Environment Assessment
Alternative Trail Alignments Area 1 • Do you agree with the trail alignments as presented? • Are any trail alignments options missing? Alternative Trail Alignments Forest Trail A Forest Trail B Common to Both Existing Trail Bridge Crossing Potential Slope Stability Issues Rail Line Crossing
