Local governments can no longer afford to pay for updating transportation, energy and public works systems critical to competing in a global economy. So West Coast government and development officials are partnering to find alternative ways to build and finance infrastructure projects. Oregon Treasurer Ted Wheeler says the nonprofit infrastructure exchange will bundle projects and link them with financing sources. It will also encourage more private investment in public projects. The goal is to develop an innovative public/private financing system that provides better collaboration between government agencies and more bang for the taxpayer's buck.
