Stormwater Permit for Equipment Storage Yard in Whitchurch-Stouffville

Official title: SCAL Properties Ltd. - Environmental Compliance Approval (sewage)

Open Regulations & Permits Environment & Climate
SCAL Properties wants to build stormwater management systems for a new equipment storage yard in Whitchurch-Stouffville. The system would include grass swales, ponds, and oil separators to treat runoff before it flows into the East Holland River watershed.

Why This Matters

Live near Lot 20, Concession 4 in Whitchurch-Stouffville? This permit affects what gets built next door. The stormwater system will discharge into the East Holland River watershed, so water quality downstream could be affected.

What Could Change

If approved, SCAL Properties can build grass swales, culverts, oil and grit separators, sewers, and wet stormwater ponds on the site. The equipment storage yard could then proceed with construction.

Key Issues

  • Will the proposed stormwater treatment adequately protect the East Holland River watershed?
  • Are the oil and grit separators sufficient for an equipment storage yard?
