It seems, from the degree of surprise among Ann Arbor city officials that this article documents, that the city has done all its “planning” without ever contacting SEMCOG and consulting its population projections. Apparently, all the zoning changes/infrastructure upgrades were based on little more than “If you build it, they will come”. Or does the city have some other authoritative source of growth – even an internal study – that SEMCOG has overlooked? Surely the city must have other data sources that support the drive to density – even the local ruling class can’t be that amateurish. What is this other data source?
