"Self-mitigating" as applied to stream crossings means the design of the crossing incorporates measures or features to offset the loss of the affected resource's functions and values in an area where the new functions and values are sustainable. Examples of self-mitigating measures or features include, but are not limited to, eliminating a barrier to aquatic organism passage, improving the hydraulic capacity of an under-sized crossing, and improving geomorphic compatibility.
