The Residential Agricultural Zone (RA) is established to provide areas on the fringes of the corporate area of Provo City where residential uses may be harmoniously integrated with incidental agricultural pursuits. This zone is intended to allow the keeping of farm animals and fowl in conjunction with one-family dwelling units to an extent consistent with said development, and in proportion to the amount of land area provided for this purpose. It is intended, at the same time, to retain land in parcels large enough to provide efficient and attractive development as urban uses extend in an orderly manner into these areas. The Residential Agricultural (RA) zone is also intended to accommodate residential developments which are oriented to an equestrian lifestyle. This would allow the design of a residential community which could contain noncommercial stables, training areas, and equestrian trails as an integral part of the development.
