The commission established in AS 44.06.060 shall determine all bondable costs and total costs including, but not limited to, the costs of moving personnel and offices to the relocation site; the social, economic, and environmental costs to the present and relocation sites; and the costs to the state of planning, building, furnishing, using, and financing facilities at least equal to those provided by the present capital city.
