Mississauga.
- Tributary #2 (east branch) between Queen Street and Highway 407 in Brampton.
- Tributary #2 in Mississauga north of Derry Road between Dixie Road and Torbram Road.

4. Retrofit Upper Nine Pond and Grey Stoke Pond in the City of Brampton to wet ponds for quality
control.

Etobicoke and Spring creeks
as they approach and flow
through airport lands.
5. Fifteen stormwater outfalls within the City of Brampton and five in the City of Mississauga
should be retrofitted for quantity and quality controls.
6. All residential and industrial areas should be serviced with wet ponds for quality controls.
7. Both existing and proposed ponds should be considered for chemical and bacterial removal if
monitoring reveals that in-stream water quality targets cannot otherwise be achieved.
8. Industrial source controls should be encouraged on surrounding institutional/commercial/
industrial (ICI) properties.
