The Estate Residential Zone (RE-1). The Estate Residential Zone is established as a low-density residential zone for families who wish the privacy of large lot subdivisions. The zone is mainly designed, however, for developments in areas which, because of their proximity to other area developments or appealing natural landscapes, are in demand for residential use, but where conditions of slope, soil, vegetation, drainage, or geological features, or an interrelationship between the aforementioned conditions makes the area in whole or part unsuited for high-density development. For this reason the granting of the RE-1 Zone must be conditioned upon:
(1) A combined zoning and subdivision process.
(2) Specially imposed lot sizes of not less than one acre.
(3) Special setback and yard requirements which would allow resubdivision when public utilities reach the site.
(4) Authorized density: not more than one unit per acre.
