9 Recommendations: Outreach – Informing the public and other political entities of the benefits  MIDOT & NGS booth at Michigan State University Farm Expo in 2013  MIDOT & NGS Presentation at Michigan Professional Surveyors Conference. Partnerships -  MIDOT and private sector involvement with IGLD GPS Survey  Possible addition of more leveling to NOAA water levels gauges near MIDOT lines (Muskegon at Great Lakes field office location).  OPUS Projects with Adjust Training at MIDOT offices  Partnering with county governments and local surveyors to update the CORS in the state.

10 Setbacks:  Michigan does not have one central agency that has legislative control over the state. Different departments have different standards than MIDOT  Finding a major funding source that is consistent for year to year operation.
