The Town of Innisfil's Belle Aire and Little Cedar Creek residents have dealt with seasonal flooding for many years. We are committed to finding drainage solutions and have begun with an Environmental Assessment Study of the problem area.

Environmental assessment

We partnered with the Lake Simcoe Region Conservation Authority (LSRCA) and Greenland International Consulting Ltd. To complete a Conservation Authority Class Environmental Assessment (EA). The EA covered the following area:

  • Approximately 350 hectares bounded by 6th Line to the north
  • Belle Aire Beach Road to the south
  • The rail line to the west
  • The shoreline of Lake Simcoe to the east
  • A small subdivision in the southeast corner north of Belle Aire Beach Road
  • Low-density housing along the Lake Simcoe Waterfront
  • Approximately a dozen rural houses along the Study area limits

Proposed solutions

The EA identified two possible solutions to help with drainage:

Preferred conveyance solution

This solution involves increasing the capacity of drainage channels by:

  • Re-shaping and cleaning out about 670 m of Belle Aire Creek through the community north of Belle Aire Beach Road
  • Culvert replacements and improvements at intersections along Temple Avenue and Maple Road

Preferred storage/by-pass solution

This solution involves creating storage systems to hold and redirect water by:

  • Constructing underground storage structures to hold flood water
  • Creating a dual outlet system for flood water to drain through Little Cedar Creek or through a high flow outlet to Lake Simcoe in emergencies

Anticipated benefits

Benefits from implementing these solutions could include:

  • A reduction in annual flooding events
  • Improved water quality in Lake Simcoe
  • Enhanced characteristics of the tributary area
  • Erosion control
  • Integrated stormwater management
