In September 2002 Highways and Transportation was informed by Department of Fisheries and Oceans (DFO) that the three hydraulic designs submitted to them did not meet the current fisheries regulations. Specifically, fish velocities, fish habitat compensation, re-vegetation techniques and proposed construction practises did not meet standard. At this point, Golder Associates Ltd. was hired to circumvent a Harmful Alteration, Disruption or Destruction of Fish Habitat (HADD) and also potential fines from DFO. The Golder Team assembled a conceptual plan that would eventually be deemed acceptable by DFO officials. The plan also met the economic needs of Highways and Transportation. After conceptual acceptance was gained Golder was once again employed to perform a detailed design on the stream crossings. Fish habitat compensation (No Net Loss concept) was achieved through the design of two Rock Weirs. This project was nominated for the 2002 Environmental Achievement Award.
