In recent decades (1980s - 1990s - ) some planned residential developments take on some of the ideas of the original Residence Parks. They have formal entrances with structure(s) and landscaping announcing you are entering the tract. They often have a carefully planned street layout that tends toward winding curves. Some include clubhouses and/or a central park. But many of these features are often at the demands of the local city when approving the project and consequently take on a generic city-park appearance. And since the developments are typically created by large companies looking to maximize the return on their investment, they build the houses too. As a result, there are often rows and rows of houses with minor variations.
