Current Work Program

The Work Program for Southeast Michigan is the document that serves as the basis for all SEMCOG activities. It contains a discussion of issues facing the region, a framework for regional decision making, and specific task activities and budgets for SEMCOG and our pass-through agencies. The Work Program is updated annually and often has amendments throughout the year as projects are added or activities change. The current Work Program and any accompanying amendments are listed below: 

Decision making
All SEMCOG policy decisions are made by local elected leaders, ensuring that regional policies reflect the interests of member communities. Participants serve on one or both of the policy-making bodies — the General Assembly and the Executive Committee. These bodies act on recommendations developed through SEMCOG's various engagement methods. We engage regional stakeholders from local governments, the business community, and other special-interest and citizen groups.
