Bayview Avenue is a major north‐south arterial corridor under the jurisdiction of The Regional Municipality of York (York Region). Located in the Town of Richmond Hill, Ontario, the lower segment of the project corridor contains a principal tributary of the Rouge River that is fed, at this location, through significant steady state groundwater upwellings from the Oak Ridges Moraine Aquifer directly below. The principal tributary and former road side ditches now all contain significant brook trout population and habitat. The watershed is managed by the Toronto and Region Conservation Authority and the brook trout habitat is managed by Fisheries and Oceans Canada.
York Region and the Town of Richmond Hill are undergoing tremendous growth in population and employment. In response to this growth, the Bayview Corridor Project improves mobility for all corridor users including motorists, pedestrians, cyclists and fish, with an innovative design enhancing the environment. The design of the project included extensive consideration of artesian conditions resulting from the Oak Ridges Moraine Aquifer and resulting brook trout habitat which contributed to the overall duration and complexity of the project.
