AN, it’s late and I will call it a DAY (for me, anyway). 4S is NOT part of RB. 4S is NOT part of a City. It is a far-flung “exurb” recently developed in the last 8-10 years. It is comprised of nearly ALL tracts. There was next to NOTHING there before 2000. The 90’s Thomas Guides I have here with their empty pages bear this out.
The eastern/northeastern part of Poway could be considered an “exurb” due to distance from fwys. It is an “exurb” but not a tract-laden exurb. Many custom homes exist in this area. It is VERY expensive in this state to build a custom home from the ground up. Persons who go thru this time and trouble DO NOT build them on substandard lots. It wouldn’t be worth the time, money and trouble to do so. Fallbrook and Bonsall are also exurbs. These areas are more well-established with many custom-built homes as well as smaller tracts which may or may not be built in the last ten years. They are “exurbs” due to distance from job centers but are not comprised of huge tracts, as 4S and Otay Ranch are.
An “exurb” is a far-flung area (established or not established) which is situated far from job centers, whose residents are largely freeway dependent. It often does not have all the retail and other services locally within it which its residents need. In addition, it is served very minimally, if at all, by public transportation.
