(2) The potential impact of the proposed tollway project on local environmental, aesthetic and economic conditions and on the economy of the state in general;

(3) The extent to which funding other than state funding is available for the proposed tollway project and the extent to which resources other than tolls would be required to be established and/or maintained as necessary security to support such a financing;

(4) The likelihood that the estimated use of the tollway project will provide sufficient revenues to independently finance the costs related to the construction and future maintenance, repair and reconstruction of the tollway project, including the repayment of any loans to be made from moneys in the transportation innovative partnerships account created under RCW 47.29.230 or other accounts;

(5) With respect to tollway projects, any portion of which will be financed with state funds or department loans or grants:

(a) The relative importance of the proposed tollway project compared to other proposed tollways; and
