Stormwater Pond Expansion for Industrial Warehouses - 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. The pond would collect water from a larger area—growing from 37 to 46 hectares. The extra drainage comes from a nearby property on Healey Road.
Why This Matters
Live near Coleraine Drive or Healey Road in Caledon? This affects how stormwater from industrial sites is managed in your area. Proper stormwater handling prevents flooding and protects local waterways.
What Could Change
If approved, the existing stormwater pond can accept runoff from an additional 9 hectares of industrial land. The pond's storage capacity and outlet controls stay the same—only the drainage area expands.
Key Issues
- Can the existing pond handle runoff from a 25% larger drainage area without changes to its capacity?
- What are the potential impacts on local water quality and flooding risk?
