Unless an alternative credit determination method is used under WAC 173-700-321, the department shall use the following considerations to determine specific conversion rates for uplands and other habitats on a bank site:

(1) Degree of contribution to the ecological functioning of the bank;

(2) The existing or proposed enhanced condition of the uplands and other habitats; and

(3) Connectivity to other habitats and open space areas, based on existing connectivity and level of protection for those adjacent areas.
