(a) The R-1 Residential Districts are established in recognition that sections of the Village include low-density residential developments that are urban in character and are developed exclusively for one-family dwellings.
(b) Among these sections of the Village is land served by centralized sewer and water, or these utilities are readily available with adequate capacity; land where the established use, character, and density of development would be best maintained by these regulations; and sections of the Village where the general welfare is best served by the provisions of these districts in providing essential services and facilities at an adequate level in an efficient and economical manner without overcrowding the land.
