While it is unfortunate that these houses, if historic, are slated for demolition, there are numerous other factors at play.

First, this picture is a perfect example of America’s blighted neighborhoods. Yes, the exterior may be attractive and nostalgic, but the interiors are likely dilapidated and unsafe. If they aren’t they soon will be. The homes may also be partially vacant, or in foreclosure. If left in this state, that attractive facade will soon crumble, and various pests and miscreants will move in. The sad reality is that homes are expensive to maintain, and even more so when they are old.

There may also be other factors such as brownfields or land contamination, perhaps emanating from a nearby former industrial facility, the storefront or homes themselves (asbestos, oil leaks, etc). This would restrict what could be built. Parking lots are often used to cap polluted land.

Unfortunately, while parking lots are not the most desirable option, they are better than crackhouses or burned out hulks, which if left abandoned these houses would surely become. At least you captured their history before they are demolished.
