Report Summary
The Big Lake Basin Study Task Force has requested the City of Edmonton to appoint a political representative to serve on this initiative and to commit $10,000 of funding for the basin study. The study will develop a stormwater management plan for the Big Lake Basin. Only a small portion of the Basin is in the City of Edmonton.
Report
The Big Lake Basin Study Task Force was put together to develop a Stormwater Management Plan for the Big Lake Drainage Basin Area that addresses existing and future drainage patterns and flooding concerns arising from increasing development within the Basin.
The Task Force is made up of one elected representative from each of the following municipalities: Parkland County, Town of Stony Plain, City of Spruce Grove, Sturgeon County, City of St. Albert, Lac Ste. Anne County and two representatives with no voting status from Alberta Environment. Currently the City of Edmonton is sitting on the Technical Committee and as observers only (no voting status) to the Task Force.
A Stormwater Management Plan will be prepared by Associated Engineering. This study will cost approximately $200,000. The Minister of Environment has agreed that this study qualifies under their existing Alberta Water Management and Erosion Control Program, therefore 65% of the project is funded. The remaining 35%, or $70,000, is unfunded. A motion at the Big Lake Basin Study Task Force has requested all seven municipalities for an equal share, or $10,000 each (Attachment 1).
Lac St. Anne County has responded by deciding to withdraw from the Task Force and any participation in funding of the study. We are not aware of any other responses at this time.
A review of the Project Issues from the consultant’s proposal (Attachment 2) and the Task Force Terms of Reference (Attachment 3) show the focus of the study. Issues that are relevant to the City include flooding around Big Lake and stormwater management requirements.
The City is a small contributor to the Big Lake Basin (approximately 0.5% of all contributing lands). Most of the City’s contributing area is either under Provincial jurisdiction, Transportation Utility Corridor (TUC) or not expected to be developed until after 2025. Contributing lands that are developing have Master Drainage Plans that restrict runoff to predevelopment rates.
The Office of the City Clerk advises that the Big Lake Basin Study Task Force would be classified as an external, intergovernmental agency pursuant to Council Policy C473B “Appointment of Members of Council to Civic Agencies”. The policy states that City of Edmonton representatives on Intergovernmental Agencies (Agencies that include more than one municipality or level of government) must be Council members.
Budget / Financial Implications
This will cost the City of Edmonton $10,000.
Justification of Recommendation
The Task Force is made up of seven municipalities, all of which are represented by elected officials, with the exception of the City of Edmonton. The Big Lake Basin Study Task Force requests that the City become a full partner through the appointment of an elected representative as part of their commitment to regional co-operation.
There is an outstanding $70,000 required to finance the Basin Study. The Task Force is asking that the cost be split equally among its seven members.
