Nine states specify the structure of the PPP proposal review process. In Washington, in order to move forward with projects with costs over $300 million, public agencies must, by statute, form an advisory committee made up of members of participating public agencies "offering a diversity of viewpoints." Georgia requires an evaluation committee made up of members from the governor's office, a designee with a finance background, and the head of the state Department of Transportation. Providing for the structure of these committees or any other method for reviewing proposals before proposals are received is a good way to legitimize the approval process and remove any questions about the process before the first proposal is received. States can structure these review committees in whatever way they see fit, but should include people with backgrounds in finance, project management, engineering, and other related fields.
