Six states require various forms of legislative approval before PPP projects can move forward. Delaware requires that the co-chairs of the state General Assembly's bond committee meet to approve or disapprove PPP proposals. Washington provides for the state finance committee to approve a project in the absence of a public benefit corporation (for example, a port authority or other infrastructure authority). Georgia does not require that the legislature approve the project, but does require that the project's sponsors present the legislature and the governor with a copy of the letter of intent to negotiate a PPP deal. Such requirements can chill private participation in PPPs, as allowing for a legislative veto late in the process dramatically increases the risk that a project will not be approved. States must be careful to weigh the public interest in managing public agency participation in PPP projects with the discouragement that such legislative approval provides. Removal of the need for legislative approval of each individual project both streamlines the PPP application process and demonstrates the state government's trust in its PPP agreement guidelines. It also provides reassurance to private contractors that the projects will be approved as long as they conform to the established PPP laws, thus lessening the political and approvals risks commonly associated with highway PPPs. As an exception, some states wish to retain legislative approval requirements during their trial programs as a way to gain experience and refine their PPP guidelines early on.
