It's not unusual on U.S. housing-development courses to have to route an emergency access road through the golf course, so that residents will have a second way out in the event of a fire.
In fact, most towns have zoning codes that limit the length of a cul-de-sac street, so that at most a handful of homes can be cut off from a point of exit in case a fire blocks the road. So, if you design a longer cul-de-sac, you have to provide an emergency access out the other end.
