INFRASTRUCTURE CONSTRUCTORS

On March 16, 2010, the Ontario Ministry of Transportation (MTO) issued Ministry Directive PLNG –

B012 which clarifies and documents the Ministry’s policy with respect to proceedings under the Drainage

Act. The purpose of the Directive is:

“To define the responsibilities and key activities for the Ministry’s area and regional staff in the initiation, review, and approval of drainage works implemented under the Drainage Act within or affecting highway rights of way and other lands owed by the Ministry, in both organized and unorganized territory. The directive is not intended to provide a detailed summary of Drainage Act procedures.”

The Road Authority, as commonly referred to in the Drainage Act, refers to the MTO or the municipality in which the roadway lies. In situations where the drainage works extend outside of the MTO controlled lands, but remains within a municipal road right of way, the Road Authority refers to the entity that is responsible for control and maintenance of that roadway. Municipal drainage works for The Parkway are largely contained within the MTO right of way. Works for the Marentette Mangin Drain will be completed under a Letter of Opinion in accordance with Section 77(3) of the Drainage Act.

3 Stormwater Management and Drainage Strategy

In order to facilitate the review and approval process, stormwater management (SWM) reports will be issued that provide stormwater and drainage design information on an outlet by outlet basis. These reports will demonstrate how the stormwater quality and quantity criteria specified in the Project Agreement are met and will include the hydrologic and hydraulic analyses completed to support the design of SWM and drainage infrastructure for The Parkway. The following individual SWM reports will be issued:

This SWM Report has been prepared to document the development of the SWM plan and the design of drainage infrastructure for the section of The Parkway associated with the Marentette Mangin Drain.

4 Study Location and Extents

The Windsor-Essex Parkway will be approximately 11 kilometres long, beginning at the current terminus of Highway 401 and concluding at the future inspection plaza at Ojibway Parkway. The Parkway will traverse through three municipalities: the Town of Tecumseh, Town of LaSalle and City of Windsor. The alignment of The Parkway, in general, will be along Talbot Road, Huron Church Road and E.C. Row Expressway.
