The Cornerstone District is approximately one square mile in size. Its boundaries are Mt. Vernon Road (9 1/2 Mile) to the north, Eight Mile Road to the south, Greenfield Road to the east, and Southfield Road to the west.
In 1999, the Cornerstone District Authority(CDA) commissioned a master plan study of the Cornerstone District. The master plan is a tool to help generate ideas for the development community regarding the overall potential of the district. The main master plan outlines the direction that the CDA board of directors has focused on. In addition, two alternative plans were generated to document a broader range of possibilities. All three documents are available here for review in Adobe Acrobat Format.
