Reasons for a Federal Assessment

On February 12, 2008, it was determined that an environmental assessment was required in relation to the project because Fisheries and Oceans Canada considered taking action in relation to subsection 35(2) of the Fisheries Act.

Project Description (as posted in the Notice of Commencement)

The Town of Richmond Hill proposes to modify an on-line stormwater management pond within Pioneer Park on the Little Don River, a tributary of the Don River. The scope of the project includes the redesign construction, operation, and maintenance of the stormwater management pond and associated approaches, along with any related works, accesses or any other undertakings directly associated with the redesign modifications, upgrades, construction, operation, and maintenance. The work will include the construction of a new control structure foundations and substructure within the tributary and floodplain, a new low-flow bypass channel, a wet pond, a dry pond, construction of a new channel section, a by-pass pipe, and local channel restoration works.

Final Decision

A decision was taken on September 23, 2008 and was that the authority may exercise any power or perform any duty or function with respect to the project because, after taking into consideration the screening report and taking into account the implementation of appropriate mitigation measures, the authority is of the opinion that the project is not likely to cause significant adverse environmental effects.
