As I've suggested before, perhaps we'll learn together what might be actually happening here, by viewing these pictures. Is there some kind of plan or intent, being followed? I'm going to strongly suggest there is and once again what resource is left, is being concentrated in areas deemed more viable in the future. I'm seeing little clusters of new homes (so people can keep an eye on the neighbors property?) Certainly, or well lets hope these new homes won't be capped over in another thirty years! Perhaps, the capped over areas are designed to be the garden plots of the future? If this is the case, and the infrastructure (mainly water) can still support these newer homes, might this become a more attractive area in the future?
I thought at first, what a waste of resource! To build something new among ruins!! However, isn't this the same kind of thinking that would "let go" whole neighborhoods (like the one next to Chene Street), to concentrate more effort and resource to the inner city of Detroit? Will these larger areas that are meadows now, better serve the city in the future, by not being occupied with new homes? See the connection here, only on a smaller scale? Perhaps, these ruins that surround the new cluster of homes will be "permitted" to fall and be capped over to better serve them in the future?
If this is the case, perhaps, in the not so distant future there will be little clusters of homes, surrounded by much more land of gardens and woods? That is, there will likely be no need to have rows of houses, block after block, if there isn't the population there to demand it. Perhaps, in this new arrangement these new homes will become more self sufficient? I would tend to think so, it's a lot easier supporting a family on a large plot of land than from a yard that was the size of a postage stamp, as was in the past...
So in view of this, I think, that catabolic collapse is an on going process, that certain neighborhoods are in different stages. Some in serious decline, some on the up bound partial recovery, and in the whole reflecting an "overlapping". A city that will see partial recovery, more deeper decline, on and on, in our foreseeable future.
