Sounds like Oregon land use law.
Actually, Oregon's land use laws are somewhat paper tigers, unfortunately.
Here in Southern Oregon, tightly-crammed subdivisions are springing up everywhere, in the forests, on wetlands, replacing farmlands, etc.
The hillsides are all being bulldozed and massive, multi-million dollar houses are being built with no yards, practically touching each other.
It's amazing how the landscape has changed...the hills are beginning to resemble the Hollywood Hills, with hundreds of mansions covering previously pristine forested mountains, and all througout the county, farmlands and woods are being replaced by gated communities and huge mansions.
It's really sad...they're destroying what Oregon once was.
I view us now as a third-world country, a colony of California. The rich retirees come in, bringing no jobs, no payrolls, just buying up and bulldozing our forests and hillsides, to build huge, 10,000 sq ft mansions fit for a British Raj in Colonial India.
Meanwhile the locals become unable to buy homes, the mills all shut down, and industry closes shop...while the crime gets worse, the traffic becomes a stop-and-go nightmare, and voila, we're suddenly in Los Angeles, or Mexico City, where a scant fraction of wealthy outsiders owns all the land and houses and the locals watch taxes and housing prices skyrocket out of any hope of ever getting a hold on it.
