6.0 Potential Enhancement and Compensation Opportunities

In situations where the application of the mitigation measures cannot sufficiently address the residual effects of the crossing on fish and fish habitat, habitat compensation measures may be required to counterbalance or offset the residual effects. As stated above the realignment of Broadway Dain will likely require authorization under the Fisheries Act.

The designs will be based on natural channel design principles and proven approaches as experienced by the design specialists. The selected designs will require approval from the regulatory agencies before implementation. Appropriate channel form and design elements will be based upon the results of detailed geomorphological assessments. Further, the natural channel design will be guided by the following principles:

• Balance of erosive and resisting forces to provide a channel in a state of dynamic equilibrium;
