Stomwater Pond Construction

Wetlands

• Existing wetlands in the Transportation Utility Corridor (TUC) are avoided wherever possible, however, due to the restricted space in the TUC, the ability to build around wetlands is also quite limited

o A narrow strip of land was acquired to minimize impact to the Tsuut’ina Nation lands

o A miss-minimize-mitigate approach was applied to minimize impacts to environmentally sensitive, culturally significant and residential areas.

o The Tsuut’ina Nation did not consider Alberta Transportation’s offer to replace wetlands on their land
