§ 154.105  RURAL RESIDENTIAL DISTRICTS (RR-1, RR-2).
   (A)   Purpose.
      (1)   The purpose of the Rural Residential Districts is to provide for varying densities of rural residential development on selected lands identified in the comprehensive plan for preservation of low density rural living.
      (2)   The RR Districts are intended to accommodate rural residential development at an anticipated magnitude or density level that does not require more than a very basic level of services, such as single local-road access, individual domestic wells and septic tank sewage-disposal systems, and rural fire protection.  Ultimate density limitations in the RR District shall be determined by prevailing lot sizes community character, compatibility with existing uses in the district, limitations of domestic water sources, soil conditions and groundwater tables for subsurface sewage disposal, and area designations identified in the Valencia County comprehensive plan. Opportunities for small-scale or intensive farm activities compatible with low density rural residential uses shall be encouraged in the RR Districts.
   (B)   Permitted uses. In the RR Districts, the following uses shall be permitted subject to the standards and limitations set forth in division (F) below:
