  • Read the Analysis of Costs and Benefits (CBA) for the SR 710 North Study Alternatives (PDF). The Analysis of Costs and Benefits for the State Route 710 North Study Alternatives was prepared in response to direction by the Metro Board. The motion directed the Chief Executive Officer to conduct a parallel cost-benefit analysis concurrent with the Draft Environmental Impact Report. The CBA is a means of applying an economic (monetary) value to alternatives (transportation proposals), which enables the costs of an alternative to be compared directly to the benefits the alternative will deliver. The CBA will be considered in conjunction with the information provided in the Draft EIR/EIS during identification of the Preferred Alternative.
