RECOMMENDATION:

THAT the staff report entitled “Kennedy Road Feedermain PD4 to PD6, Class Environmental Assessment” be received;

 

AND THAT the preferred alternative alignment for the construction of the Kennedy Road feedermain as set out in the Class Environmental Assessment prepared by the City of Toronto and Region of York, be endorsed subject to the following conditions:

·        The City of Toronto and Region of York enter into suitable Agreements with the Town for the acquisition of easements over Town properties.

·        The design of the watermain be subject to the review and approval of the Town of Markham as it relates to the impact of construction on municipal services.

·        The City of Toronto and Region of York prepare a detailed traffic management plan for the project and that this Traffic Management Plan be subject to the review and approval of the Town of Markham as it relates to the impact of construction on the local road network.

·        The City of Toronto and Region of York prepare a  Public Communication Plan relating to traffic, noise and other potential construction impacts of the project and that this Plan be subject to the review and approval of the Town of Markham;

 

AND THAT the Mayor and Clerk be authorized to enter into Agreements with the City of Toronto and York Region as required with respect to the conveyance of easements and other items relating to the implementation of the project, in a form satisfactory to the CAO, the Town Solicitor and the Commissioner of Fire and Community Services;

 

AND THAT Staff be authorized and directed to do all things necessary to give effect to this resolution;

 

AND THAT Debbie Korolnek, General Manager, Water and Wastewater of the Region of York and Michael D’Andrea, Director of Water Infrastructure Management of the City of Toronto be advised of this decision.

 

PURPOSE:

The purpose of this report is to seek Council’s endorsement of the preferred watermain alignment proposed by the City of Toronto and York Region in the Kennedy Road Class Environmental Assessment. 

 

 

 

 

 

 

BACKGROUND:

The Toronto/York Joint Optimization Study(JOS) completed by the City of Toronto and the Region of York in March 2006 identified water system requirements to supply future growth in both Toronto and York Region. The program recommended by the JOS included expansion of the water treatment plant and pumping station in Toronto, the expansion of the Milliken Mills reservoir in Markham and the construction of a new large diameter watermain (1200mm and 1500mm diameter) to connect the City of Toronto pumping station located south of Steeles Avenue to the Milliken Mills reservoir and the Region of York’s trunk watermain on Major Mackenzie Drive. Subsequent to the completion of the JOS, the City of Toronto and York Region undertook a Class Environmental Assessment to identify the preferred route for the new watermain.  The proposed watermain will provide increased water supply to Markham Pressure District #6 in order to meet short and long term growth demands in this area.

 

DISCUSSION

Recommended Alternative

The recommended alignment follows the existing Kennedy Road right-of-way with a connection to the Milliken Mills reservoir through a proposed easement located between the Milliken Mills High School and the Community Centre. The proposed watermain will require a crossing of the Rouge River and 2 piped tributaries together with crossings of Highway 407 and three railways. The exact location of the watermain within the right-of-way will be determined during the detailed design phase of the project expected to commence in 2008.

 

Easements from the Town of Markham Required

The connection to the Milliken Mills reservoir is proposed to be installed across Town owned land within an existing easement.  This easement was previously identified in the report to Council entitled “Milliken Reservoir and Pumping Station Expansion Class Environmental Assessment” presented on June 19, 2007.  Attachment A shows the easement related to this specific EA.

 

The existing easement agreement permits only the maintenance of the existing watermain and therefore a new easement agreement will have to be negotiated with Toronto and York Region.

Staff are requesting that the Mayor and Clerk be authorized to execute this easement agreement subject to the approval of the CAO, Town Solicitor, and Commissioner, Community and Fire Services.

 

Potential Impacts

Dewatering

Two potential areas along the proposed route which may require dewatering have been identified in the EA, at the Rouge River crossing south of 16th Avenue.  Additional hydrogeological and geotechnical investigations will be carried out in these areas during the design stage of this project to determine any potential impacts.

 

 

 

 

Impacts to Town Services

The Town has a number of local services (sanitary and storm sewers, watermains) along the route of the proposed watermain that may be impacted during construction. The location and extent of these impacts will be identified during the detailed design phase of the project.  The Engineering and Asset Management staff will be involved in the review and approval of the detailed designs to ensure that the Town’s infrastructure is adequately protected.

 

Traffic Impacts

The construction of the watermain will have impacts to traffic along Kennedy Road and adjoining streets from Steeles Avenue to Major Mackenzie Drive.  It is anticipated that construction will occupy at least one lane of traffic for the majority of the two year construction timeframe for the project and that temporary closures of local streets, driveways and entrances will be required as construction proceeds.  Engineering staff has requested and the City and Region have agreed that the Town will be involved in the review and approval of traffic management plans for the project.

 

Public Consultation

The Environmental Assessment for the Kennedy Road Feedermain has followed the public and stakeholder consultation process requirements for Schedule ‘B’ projects as set out in the Municipal Class EA. This consultation process involved the publishing of a Notice of Project Commencement, two public open houses, meetings with various stakeholder groups and reviewing agencies and the publishing of a Notice of Study Completion. Comments received during this consultation process have been incorporated into the final EA document.

 

Construction Schedule

Currently construction on the Kennedy Road feedermain is scheduled to start in 2010/2011 during the later phases of the Milliken Mills Reservoir expansion project.

 

FINANCIAL CONSIDERATIONS AND TEMPLATE: (external link)

The construction of the watermain is to be funded entirely by the City of Toronto and Region of York. The Town may incur costs for the relocation or replacement of Town services however, these costs, if any, can only be determined during the detailed design phase of the project. Staff will report back to Council if any Town costs require authorization by Council.

 

ENVIRONMENTAL CONSIDERATIONS:

The alignment of the new feedermain was selected through an Environmental Assessment process to minimize the potential impacts to the environment.

 

ACCESSIBILITY CONSIDERATIONS:
