But, you still have to plow and light the same length of street, trash pick-up still has to drive the same number of miles, etc...if you're going to do this stuff, it better be actual infill, and in stable or stablized neighborhoods or stable or stablizing
sections of neighborhoods. The very worst thing that could be done reducing density from the perspective of a local government. They need to be cramming as many folks on an acre as they can get, and cutting off the surplus, contiguous land either for development or for things like gardens if or until the land becomes desirable again for development.
You know, I don't mind rebuilding in a place like Brightmoor, so long as they build around something, actual neighborhood cores. Simply spreading out the housing defeats the purpose. City planners need to be smarter about this; I'm glad to see that at least in Detroit they are finally in the first stages of being smarter about land use.
I know we're kind of getting slightly off subject about what Saginaw's doing in particular, but it was important to comment on "right-sizing" in general. I actually think what Saginaw's doing is worth a try, something similar is being doine here in Lansing and other communities around the state through land banks.
BTW, anyone interested into going deeper into this can read the Michigan State Housing Development Authority's plans on this across the state:
