The Greater Cardinal Creek Subwatershed Study was initiated to address three land use planning and environmental issues including the following:
- Environmental impacts of urban and rural development pressures within the study area;
- Documented water quality problems within Cardinal Creek; and
- Documented erosion and slope stability concerns along Cardinal Creek.
The study was planned and conducted in accordance with Official Plan Policy 2.4.3 – Watershed and Subwatershed Plans which identifies and protects the natural heritage system, recommends areas for development and preservation, provides guidelines for development and includes monitoring of all aspects of the plan.
The Subwatershed Study was also conducted as a Master Plan Municipal Class Environmental Assessment (Class B), with respect to the erosion and slope stability concerns along Cardinal Creek and documents the extent and nature of the concerns, evaluates the alternatives for addressing the problems, and identifies the preferred solution. Upon approval of the Subwatershed Study by Council, the City will post the Subwatershed Study for a mandatory 30 day review period under the Environmental Assessment Act, and then issue a Notice of Completion.
The Greater Cardinal Creek Subwatershed Study occurred in three phases including preparation of the terrestrial inventory and geomorphic assessment (2006-2007), preparation of the existing conditions report (2008-2009) and the preparation of the subwatershed management plan, which is the focus of this study and report herein.
A portion of the study area came under consideration for urban expansion (Urban Expansion Study Area 11) during the 2009 Comprehensive Official Plan Review (OPA 76) and subsequent appeals. After confirmation of Area 11 as an urban expansion area, the scope of the subwatershed study increased to include the development of stormwater management and other environmental guidelines for development of Area 11 (the Cardinal Creek Village development area).
This Subwatershed Management Plan includes identification, policies for protection and potential habitat restoration opportunities for the natural heritage system. This plan places an emphasis on Low Impact Development (LID) techniques in stormwater management and verification of flow targets for future development within the watershed. The protection of surface water and ground water features are reviewed and an inventory of agricultural land uses and Best Management Practices is included.
The Greater Cardinal Creek Subwatershed Study satisfies the technical requirements of the Master Plan Municipal Class Environmental Assessment (EA) with respect to the erosion and slope stability concerns along Cardinal Creek. The project was completed as a Class B Environmental Assessment, which addresses Phase 1 and Phase 2 of the process: i.e. identification of the problem, identification and evaluation of alternatives, and identification of a preferred alternative.
