Our school project is located to plenty of basic services in the "downtown" area of a rural community. But, I'm wondering if there is any specific definition of "residential area or neighborhood." There are several areas within the 1/2 mile radius that have large apartment / condo complexes but not sure if that is defined as a neighborhood?

Also, for a service to count, it's actual front door has to be within a 1/2 mile of the school's front door, is that correct? Can it be any entrance?
