What was the Original Project
The basis for the project was to intercept flows
from the existing YDSS sewer on Yonge Street to
alleviate capacity constraints in the existing
system

• Class EA Completed June 2003
• Detailed Design 80 Completed Oct 2004
• A diversion manhole was to be constructed at the
  southeast corner of 19th Avenue and Yonge Street
  followed by a 1500 mm (60 inch) sewer from Yonge
  Street to Leslie Street. A 2100 mm (84 inch)
  sewer would then be constructed down Leslie
  Street which would connect into the existing
  Leslie Street trunk sewer approximately 100 m
  north of Elgin Mills.

What Changed October 1, 2004

• Minister of the Environment received bump-up
  request on project
• Minister subsequently Denies Bump Up Request with
  Conditions

• Overview of Conditions
• Comprehensive review of alternative routing
  options and alternative sewer design and
  construction techniques.
• Pro-active, strategic, and ongoing Stakeholder
  Relationship Management
• Technical assessments sufficient for all permits
  and approvals
• Analysis of cumulative effects of dewatering
  combined with other Regional projects
• Independent Peer Reviews
• Technical resource for individual well
  complainants
• Additional monitoring and reporting requirements
  during and after construction
• More frequent, effective, interactive public
  communication

How will the Public be Consulted?

• Established a multi-stakeholder advisory
  committee
• Regular Public Information Forums - next one
  February 8th, followed by another sometime in
  March
• Additional Outreach Initiatives
• Periodic newsletters with project up-dates
• Public Consultation Web Site to keep stakeholders
  informed and to solicit feedback (more
  information in a few weeks)

What are potential stakeholders concerns?

• Concerns regarding the Oak Ridges Moraine,
  Jefferson Forest, Headwaters to the Rouge and
  fish habitat
• Impacts to residents private wells
• Construction nuisance and construction impacts
• Timing of works

9
How Will the Routes be Evaluated

• Natural Environmental Considerations
• Potential impacts to water resources and natural
  heritage features
• Social/Cultural, Economic/Financial,
  Legal/Jurisdictional
• Potential disruption during construction,
  potential impacts to archaeological and built
  heritage resources, and compatibility with
  current and future land uses
• Estimated capital costs and operating and
  maintenance efficiencies
• Potential land requirements
• Technical Considerations
• Constructability, flow capacity, dewatering
  impacts, and potential conflicts with existing
  utilities and infrastructure

10
Design/Construction Alternatives

• Open Cut Sewer Installation
• Pump Station/ Forcemain
• Lift Station
• Tunneling (Earth Pressure Balance Machine)
