The Policeman’s Flats rehabilitation project was required to be completed by Alberta Sustainable Resource Management (Formerly Alberta Fish & Wildlife) due to the Floods in 2005, which caused massive damage to the existing wetlands. The objective was to recreate an atmosphere by using as many recycled materials, and to construct with minimal impact to the wetland.

Scope of work included:

  • Create an access road as per specification to the boat launch entrance with Tri-Lock & Geotex 861 non-woven geotextile cushion fabric, and fill the void space with gravel. There was approx. 2000 m2 of Tri-Lock required to complete road.
  • Install 160 l.m. of Turbidity Curtain to reduce sediments entering the river while working in the stream.
  • Construct 110 m (400m3) Vegetated Gabion Wall. Gabion Wall was seeded & vegetated with over 10,000 plantings (completed by DDS Consulting) Plants were installed as bare rootstock.
  • Install over 5000 m2 of erosion matting on the side slopes and areas where vegetation needed to be re-established.

AGES portion of construction was completed in approx. 35 days and the project was completed on time and on budget. Alberta Sustainable Resources Ltd. was very pleased with the outcome of the project. This was a very good collaborative effort between Caliber Systems and AGES to complete this project in such a short window. Policeman’s Flats will be handed over to the City of Calgary Parks & Recreation to maintain the wetland.
