Ladies' Golf Club of Toronto Slope Stabilization Project
Toronto and Region Conservation Authority (TRCA), in partnership with the Town of Markham, seeks to address a large slope failure on a section of valley wall at the northern property limits of St. Volodymyr's Ukrainian Catholic Church above the Ladies' Golf Club of Toronto, which has created a risk for users of the parking lot and ongoing maintenance for the Golf Club to remove sediment deposition and repair water-damaged areas on the 16th green.
In accordance with the Environmental Assessment Act, the proposed undertaking is being completed under the Municipal Class Environmental Assessment (Municipal Class EA); the prescribed process for projects of this nature. A detailed design has been developed through the Municipal Class EA process that will provide long-term protection for the Church parking lot, the valley wall and the Golf Club property.
Background of Project
It is understood that the initial slope failure occurred during the severe storm event of August 19th, 2005, when a large volume of storm water flowed through the Church parking lot and over the slope crest to the Golf Club property in the floodplain below.
Since the initial failure in August 2005, shallow slides continue to occur resulting in further damage to the parking lot, an ongoing loss of mature trees on the valley wall, and ponding of water and sediment buildup on the 16th green of the golf course.
Planning Mechanism for the Undertaking
The project is following the planning and design process prescribed in the Municipal Class Environmental Assessment for Water and Wastewater Projects (Class EA) for Schedule "C" projects. The Class EA requirements for Schedule C projects are listed below:
Phase 1: Definition of the Problem;
Phase 2: Identification and Assessment of Alternative Solutions;
Phase 3: Identification of Alternative Methods; and
Phase 4: Preparation of the Environmental Study Report.
These phases identify any potential negative and positive effects with the implementation of a project. TRCA will document the decision making process and the value judgments made in selecting the preferred course of action in an Environmental Study Report, including a description of alternative designs for the undertaking and detailing potential effects of the project. The ESR will be submitted to the Ministry of the Environment (MOE) for approval.
The Notice of Intent available below was published in the local newspaper, the Markham Economist & Sun, on August 26, 2010 and August 28, 2010 to inform the local community of the commencement of the Ladies Golf Club of Toronto Slope Stabilization Project, and to advise the public of the mechanisms by which they can participate in the project.
Update - July 2011
Given the range of solutions initially evaluated, this project was initiated under a Schedule C study of the Municipal Class Environmental Assessment process as outlined above. Following an evaluation of the alternative options and the selection of the preferred alternative, the project schedule was downgraded to a Schedule B study. A Screening Report has been prepared to document the Environmental Assessment process, including the problem definition, the site conditions, the decision-making and value judgments made in evaluating the alternative options, the preferred solution, and public and agency consultation. An electronic copy of the Screening Report is provided below.
Public and Agency Consultation
The Municipal Class EA process provides that all views be taken into consideration during the planning and design phases of the project. In addition to the development of a comprehensive project contact list comprised of concerned citizens, local interest groups, government agencies and and non-governmental organizations who have received project information and provided comment as the project progressed, a Public Information Centre (Open House) was held on January 27, 2011 to provide detailed information regarding the project, obtain feedback on the evaluation of alternative options in determining the preferred remedial measure, and address any concerns raised regarding the proposed works prior to finalizing the Screening Report.
A Notice of Completion has been prepared to advise the public that the preferred measure of slope stabilization has been identified, and that the Screening Report is placed on public record for thirty (30) calendar days commencing July 21, 2011; a copy of the Notice is provided below. The Notice of Completion was published in the July 21, 2011 and July 23, 2011 editions of the Markham Economist & Sun. As stated in the Notice, any persons with comments should provide them in writing within thirty (30) calendar days to:
Senior Manager, Environmental Engineering
Toronto and Region Conservation Authority
1 Eastville Avenue, Toronto, ON M1M 2N5
Tel: (416) 392-9725
Every effort will be made to address concerns raised, however if concerns arise regarding the project that cannot be resolved through discussions with the above, a person may request that the Minister of the Environment elevate the project to an Individual Environmental Assessment. (known as a Part II Order). The Minister must receive Part II Order requests within 30 calendar days of the date of this Notice. A copy of the request must also be sent to Moranne McDonnell at the above address.

11th Floor, Ferguson Block
Update - Notice of Construction
Following successful completion of the Municipal Class EA process on August 21, 2011 and pending the receipt of the necessary approvals, implementation of the undertaking is tentatively scheduled to commence on September 6, 2011 for approximately four (4) weeks.
The preferred solution involves filling and re-grading the failed area with free-draining materials and constructing a small drainage channel down the stabilized valley slope to a swale in the golf course. The re-graded slope will be protected against erosion through the application of a blend of composted topsoil mixed with native seed mix and organic ingredients to promote the development of a healthy herbaceous layer on the slope face while planted native trees and shrubs become established.
