Portland is committed to continuous planning and this is the third time the Master Plan has been updated since 2002; once in 2008, and again in 2010 with the development of a sub area concept plan for the 58 acres that the City acquired on East Grand River Avenue south of I-96.

Community planning is a dynamic process that does not end with the completion of the Master Plan. Urban area experience constant change. Planning involves identifying and responding to change. In order to sustain the planning process, generate positive results, maintain momentum, and respond to change, the Master Plan is reviewed and updated on a regular basis. State law now requires that the Planning Commission review the Plan every five years, and determine if it needs to be updated or revised.
