Least cost planning was defined by the 2009 Oregon Legislature in the Jobs and Transportation Act (House Bill 2001): "Least-cost planning means a process of comparing direct and indirect costs of demand and supply options to meet transportation goals, policies or both, where the intent of the process is to identify the most cost-effective mix of options." The Oregon Department of Transportation (ODOT) is now working with stakeholders to develop a least cost planning methodology that will meet the definition above. ODOT expects LCP to enable a more comprehensive evaluation of possible solutions and improve consistency, transparency, and accountability for decisions made with LCP.
Phases 1 and 2 of the LCP project are now complete, resulting in a framework of decisions guiding LCP development and a LCP draft analysis tool and user guide. Phase 3 of the project has begun, providing an opportunity to test and review the Mosaic analysis tool and process for its use and make any needed revisions. Least Cost Planning also has a new name - Mosaic: Value and Cost Informed Planning. While this website has the project history and key products to date, there is now a companion website available. The new Oregon Mosaic website has much more information about the new Mosaic use process and analysis tool, including our draft user guide. Please recognize that the information on the new website is draft and will be updated once our current testing phase is complete.
The STIP Stakeholder Committee is serving as the LCP development project steering committee.
