Stormwater Pond Expansion for Industrial Warehouses - Coleraine Drive, Caledon
Official title: ONTARI Holdings Ltd. - Environmental Compliance Approval (sewage)
A company wants to expand a stormwater pond that handles runoff from industrial warehouses in Caledon, Ontario. The pond's drainage area would grow from 37 to 46 hectares to include a neighbouring property on Healey Road. The pond itself stays the same size—just the area draining into it gets bigger.
Why This Matters
Live near Coleraine Drive or Healey Road in Caledon? This affects how stormwater from nearby warehouses is managed. More runoff flowing into the same pond could matter if you're concerned about flooding or water quality in the area.
What Could Change
If approved, the stormwater pond would officially handle runoff from an additional 9 hectares of industrial land. The company wouldn't need to build a separate pond for the Healey Road property. The Ministry would update the Environmental Compliance Approval to reflect the larger drainage area.
Key Issues
- Can the existing stormwater pond handle runoff from a 25% larger drainage area?
- Will keeping the same pond size and outlet controls be adequate for the increased flow?
