Ardwold Gate Combined Sewer
and Class Environmental
Tuesday, December 2, 2008
Thanks for joining us today for the Open House regarding the
Ardwold Gate Combined Sewer Class Environmental
Assessment Study (Class EA). This study is being undertaken
by the City of Toronto.
Public participation is an integral part of this process, so please
provide us with any comments, concerns or questions you might have.
Objectives of Open House To present the alternatives for the Ardwold Gate Combined Sewer Class Environmental Assessment Study To provide an overview of the Class Environmental Assessment Process To provide an opportunity for the public to meet the Project Team and discuss any issues or concerns they may have.
To provide a forum for further comments and receive input from the public and interested agencies.
Attendees at this Open House to:
Sign-in at the front desk Meet with Project Team Members Review proposed alternatives for Ardwold Gate Combined Sewer Discuss the alternatives, impacts on properties, community benefits, and any other issues that you may feel are important.
Complete a study ‘Comment Sheet’ to submit your questions, concerns and other comments concerning the project.
Background The existing 400 mm combined sewer has been inspected and been determined to be in poor condition and nearing the end of its design life There are significant encroachments over the existing sewer making access/maintenance difficult/impossible In an emergency situation (i.e. sewer collapse) work crews will not be able to access the sewer The purpose of this study is to examine alternative solutions to the existing condition Study Area Municipal Class EA Planning and Design Process The City of Toronto is conducting this study in accordance with the Municipal Engineers Association (MEA) Municipal Class Environmental Assessment document, amended in 2007.
The Class EA Process includes:
Public and review agency consultation Evaluation of alternatives Assessment of the impacts of the proposed improvements Identification of measures to mitigate any adverse impacts The process varies depending on he Class EA ‘Schedule’. This project is currently being carried out under a ‘Schedule B’, and is subject to change depending on which alternative solution is selected.
Alternatives Being Considered Rehabilitate the existing combined sewer and secure A) new easements. This alternative will not solve the access problem Tunnel a new combined sewer to Davenport Road via B) the south end of Ardwold Gate and the Spadina House property New storm and sanitary sewer within the Ardwold Gate C) road allowance. New storm sewers on Spadina Rd., Castleview Ave., Walmer Rd. and Austin Terrace New
*Note : This list of criteria and considerations is not an exhaustive list and is subject to change.

There is a combined sewer located at the end of Ardwold Gate that extends 200 metres south to Davenport Road; the sewer has recently been inspected and determined to be in need of repair. There are also several encroachments along the southern end of the sewer, making it difficult to access and maintain/repair.
Due to poor condition of the sewer and encroachments on top of the sewer, the City is initiating a Municipal Class Environmental Assessment (Class EA) study to determine a preferred route for the replacement of the existing sewer Question 1. – Route Options
A) Four options have been identified as potential routes for the new sewer: Alternative A: “Rehabilitation”;
Alternative B: “Tunneling via Spadina Museum”; Alternative C: “New Construction – Ardwold Gate and South on Spadina Rd.” Alternative D: “New Construction – Ardwold Gate and North on Spadina Rd.” Which route do you prefer and Why?
B) Do you have a different route alternative that you think we should consider? If so, please explain why you think your proposed alternative solution should be considered.
Question 2. - Criteria The project team is currently examining a number of criteria to determine the best solution for the problem.
This criteria includes capital costs, tree impacts, property impacts, construction feasibility, and how well the solution addresses the original problem.
Are there any other evaluation criteria that you would like us to consider?
Question 3. - CommentsDo you have any additional comments?
Question 4. – Getting to know you

Ardwold Gate Combined Sewer Replacement Municipal Class Environmental Assessment Study Notice of Public Open House #2
Please join us at our second Public Open House to learn about the results from the evaluation of the alternative routes, introduce the recommended preferred alternative, and identify the next steps in the study.
Drop in anytime to view information displays and speak one-on-one with staff. Details are as follows.
Date: Wednesday, December 16, 2009 Time: 6:30 p.m. to 8:30 p.m.
Location: City of Toronto Archives 255 Spadina Road
The City of Toronto initiated a study to address the replacement of a combined sewer along Ardwold Gate to Davenport Road. The existing sewer is in need of repair and there are significant encroachments making access and maintenance difficult. This study is being carried out as a Schedule ‘B’ project under the Municipal Class Environmental Assessment (amended in 2007) process.

Welcome Ardwold Gate Combined Sewer Municipal Class Environmental Assessment Study
View displays and discuss the study with project staff Feel free to ask questions and fill out a comment sheet Tonight’s Open House
The purpose of tonight’s meeting is to:
• Provide background on the study,
• Present the results of the evaluation of the alternatives,
• Present the preferred route,
• Receive your comments, and
• Outline the next steps in the study.
The purpose of the study is to:
• Replace the combined sewer along Ardwold Gate to Davenport Road.
• The existing combined sewer along Ardwold Gate has been inspected and is in poor condition and nearing the end of its design life.
• There are significant encroachments over the existing sewer making access and maintenance difficult.
• There is a concern that in an emergency situation (i.e.
sewer collapse) work crews will not be able to access the sewer.
Study Area The Study Area is bounded by Spadina Road, Ardwold Gate, Davenport Road, Austin Terrace and Castleview Avenue.
Municipal Class Environmental Assessment (EA) Process
• The City of Toronto must follow the Municipal Class EA process to meet the requirements of Ontario’s EA Act for all infrastructure projects.
• The EA Act requires the “protection, conservation and wise management of the environment” while undergoing infrastructure enhancements.
• Route A, which would require the rehabilitation of the existing combined sewer has been eliminated from further evaluation as it will not solve the access problem.
Three alternatives were carried forward for evaluation:
• Route B: Tunnel a new combined sewer to Davenport Road via the south end of Ardwold Gate and the Spadina House property.
• Route C: Construct a new storm and sanitary sewer within the Ardwold Gate road allowance. New storm sewers on Spadina Rd., Castleview Ave., Walmer Rd. and Austin Terrace.
