Developers are almost transparent. They don’t give a crap about the communities they create or destroy. Then only care about profit.
So what is a developer to do if the real estate market tanks and they are left holding a bunch of land that can only have high-quality, low density single family homes built on it?
Simple, write a law (or 3) and hand it to New Castle County Council. Make the law say that you can convert your plans for beautiful, low density single family homes into a plan for poorly constructed, multi-family dwellings with no review by any state or county planning agency. County Council will certainly approve it, since the only people that show up to discuss the law are the lawyers paid by the developers to attend.
In no time, you can have your apartments built, bought by landlords and you can retire to a small, undeveloped island and spend your days not thinking about the scrambling of school districts, county services, DNREC, DelDOT, etc.
I’m in the wrong business.
