The purpose of this district is to provide for areas of open space or of managed growth in which agricultural uses of land may establish or continue until such time as the City is able to provide municipal services required of urban development. In some areas agricultural uses may be the ultimate preferred development. Upon the provision of municipal services, the City or a property owner may initiate rezoning of property for uses consistent with the intended use of the property in the future. Accordingly, A districts are illustrated on the Zoning Map as to their future intended land use by the designations of either A (for agricultural use) A-R (for residential use), A-C (for commercial use), or A-I (for manufacturing use).
