I am not having luck finding the numbers for the totality of homes flooded as a result of this storm. I can only find loose numbers like 18,000 homes flooded in Warren, 30,000 in Macomb county and 10,000 in Dearborn. But what of other communities? Does anyone have numbers from their location to add to these?

Also, is there any metropolitan-level authority that oversees and gathers this data, or is it county by county?

I suspect the ongoing FEMA assessment would eventually reveal those numbers.
