The Professional Office zone is intended to provide opportunities for the location of professional and commercial offices and their related uses in close relationship to one another outside of commercial districts; to provide adequate space to meet the needs of such offices for off-street parking and loading space; and to protect such offices from noise, disturbances, traffic hazards, and other objectionable influences incidental to commercial and industrial uses. The Professional Office zone is also intended for application to those areas of the city where it is necessary and desirable to encourage the full development of properties which lie between residential and nonresidential districts and which, because of neighborhood conditions, amount of vehicular traffic, and location factors, cannot be practically included within residential districts as provided by this chapter.
