Municipal Class Environmental Assessment Study Read a PDF version here. In 2008, the City of Toronto initiated the Don River and Central Waterfront Project – a Class Environmental Assessment (Class EA) study to further the recommendations of the City’s Wet Weather Flow Master Plan on a solution to improve water quality in the Don River and along the Central Waterfront. A main source of water pollution is stormwater runoff and combined sewer overflows, which contain a mixture of polluted stormwater and untreated sewage, and are released from outfalls into Toronto’s waterways after heavy rains or snowmelts. The preferred solution includes new underground infrastructure and a treatment facility that will capture and treat polluted stormwater and combined sewer overflows before they enter Toronto’s waterways. It also includes upgrades to the Don Sanitary Trunk Sewer system to help service future growth, including twinning of the Coxwell Sanitary Trunk Sewer to ensure the system’s safe operation. In June 2011, a series of Public Information Centres (PICs) was held to present and receive input on the preliminary preferred design concept for the preferred solution, which includes new underground tunnels, storage tanks and shafts, connections points, a pumping station and a treatment facility for wet weather flows. Based on the consultation feedback and further evaluation since the PICs, the preferred design concept has been modified as follows:
- Underground vertical storage shaft at Little Norway Park has been moved to the Keating Railyard site (east of the Don River near Lakeshore Blvd East).
- Underground vertical storage shaft at the York Offramp parkette has been moved to the Keating Railyard site.
- Underground vertical storage shaft at the Rees St. Parking Lot at Queen’s Quay has been moved to the Keating Railyard site. Temporary use of the Rees Street site as a tunnel boring machine shaft is being recommended. This is required for construction of the Inner Harbour tunnel. A portion of the site will be disrupted temporarily for a two to three year duration during construction. Following construction, the site will be restored, with only a small access hatch remaining.
