Shows areas that, under current regulations, are open to new development. Many areas of the state held in private ownership are under some sort of restrictions on development, due to for example the Williamson Act, Timber Production Zoning, or conservation easements. Areas of forest and rangelands not under such constraints are more vulnerable to development. In particular, areas of forest and rangelands recently or currently being withdrawn from Williamson Act or other protections can indicate places where new developments are more likely to occur.
