1. This district is intended for exclusive application to the following areas which are designated by the general plan to be held in reserve for future urban expansion:
   1. Areas designated as low density residential reserve.
   2. Areas designated as medium density residential reserve.
   3. Areas designated as light industrial reserve.
   4. Areas designated as heavy industrial reserve.
2. The purposes of this district are to: (1) preserve the availability of agricultural and vacant lands required for future urban expansion; and (2) to prevent the premature development of lands where the range of municipal-type services required by the general plan are not yet available. When such services are available, the property should be rezoned to the appropriate general plan designation. This district is also intended to expedite the conversion of a limited amount of agricultural lands to urban uses consistent with the general plan, through the granting of a conditional use permit in lieu of requiring change of zone (amendment) procedure prior to actual development.
