The O-3 office-limited commercial district is intended to permit selected business uses in locations convenient to residential areas, where the character of the business uses are such that they predominantly serve local needs; to encourage the grouping of such local-serving business uses with safe and convenient vehicular and pedestrian access, so that traffic congestion will be alleviated; and to ensure a proper relationship between the business district and adjacent residential uses by maintaining compatibility of scale through height and yard requirements.
