CBO
This is how this works, just in case you do not understand it.The developer does not own the land. The community (lot owners) own the land. Kind of like a condo association. The lots were drawn out and sold over 50 years ago. It least half of them are built on. I don't think they would ever agree to increase the density.
A developer wants to buy a large plot of land and create a gated community. They go through a development process with the municipality, county, and even the state sometimes to get approval and even put up surety bonds. Many, if not all, of these are PUDs. The developer has options. They can subdivide the land into lots and sell them off, often with the option to be the sole builder. There need to be roads and infrastructure, which the developer needs to pay for. If it is to be a gated community with an HOA that relieves the municipality of road and sewer maintenance but not police and fire, the developer can also not subdivide and create a large townhome community or apartment community. Eventually, the developer will sign over the responsibility to the HOA association. So, from the beginning, the municipality determines what can be built where.
