For the purpose of calculating FAR, lot area shall not include private rights-of-way that serve as the equivalent of a private street for the site, but shall include private rights-of-way that provide access to service, loading, or automobile parking areas.
FAR provided in the development standards shall be limited to two (2) decimal places.
