(A) Purpose. The ER Estate Residential District is established to provide an environment for the development of predominantly large lot single family dwellings. This district is intended to promote low density residential uses of a semi-rural character. The ER District is established in areas where large lot single family residential uses are the optimum use because of location, topography, soil characteristics, wetness, vegetation, or other natural or human-induced factors, and where portions of the land may be kept open to protect and conserve wetlands, prairies, wooded regions, and other unique areas for the public benefit and perpetuation of the diversity of natural ecosystems.
(B) Policy. To achieve the purpose of the ER Estate Residential District, it shall be the policy of the village:
