Four Valley Pond

What is a stormwater management facility?

Stormwater management facilities include wet ponds, dry ponds, wetlands, underground storage chambers and other stormwater infrastructure implemented to drain stormwater runoff.

 

A stormwater management facility reduces volume, flow rates and pollutants from stormwater runoff.

 

The City of Vaughan is committed to keeping these ponds functioning through the Stormwater Management Facility Improvements Program. Currently, infrastructure improvements are underway at various stormwater pond locations across the city.
