Its almost impossible not to have them if you have commone buildings. I used to not get them with free standing homes and lots but I found out a lot of localities basically sorta force new construction to be like this so they don't have to provide services. Its made as a community which has to manage its own garbage and the local water/sewer lines so the locality only has to worry about the connection going to the community. This way they get taxes but don't really have to provide services.
