Permitted principal uses. The O-1 district is designed to permit business offices, professional offices and administrative offices in relatively close proximity to the R-B district, which will contribute to the creation of a town center, and also to permit uses that are compatible and complementary to the R-B district. Those principal uses permitted in the O-1 district are:
(1) Business offices, administrative offices and professional offices;
(4) Conference centers/hotels containing at least 150 hotel rooms.
