In order to implement the purpose of this Zoning Ordinance, the city is hereby divided into 14 classes of districts, with the designations and general purposes listed below and the specifically permitted and prohibited uses tabulated in Art. 1333:
(a) Industrial MH District. Primarily for manufacturing, assembling and fabrication activities, including large-scale or specialized industrial operations requiring good access by road and/or railroad and perhaps requiring special sites or services;
(b) Industrial ML District. Primarily for light industrial and warehousing activities which do not require a central location;
(c) Commercial CC District. Essentially the same as the Commercial CBD District, but with off-street automobile parking required;
(d) Commercial CBD District. Primarily for the conduct of retail trade, administrative and professional offices and service to the general public in the Central Business District, with emphasis on large-scale stores and specialized shops serving a regional trading area;
(e) Commercial CS District. Primarily for wholesale, warehouse and service activities which require a central location;
(f) INST Institutional District. Residential in character but primarily for institutional and office uses and including commercial activities having only limited contact with the general public, not involving the sale of merchandise at retail except incidentally and which may be carried on with no objectionable conditions in structures surrounded with ample open spaces;
(g) Residential R1A District. Exclusively a one-family detached dwelling district with adequate lot areas required and including the customary accessory uses;
(h) Residential RIB District. Primarily a one-family detached dwelling district with adequate lot areas required and the customary accessory uses;
(i) Residential R2 District. Primarily a one-family attached dwelling district with small lot areas per family but including occasional one-family detached dwellings on larger lots and the customary accessory uses;
(j) Residential R3 District. Primarily a multi-family dwelling district with small lot areas per family but including one-family detached, one-family attached and two-family dwellings, certain residential related uses and the customary accessory uses;
(k) Residential RU District. Provides a means for encouraging the development and redevelopment of portions of the city into viable urban areas where a mix of single and multi-family dwellings as well as residentially-related institutional, recreational and commercial activities are provided as a unified project and where development on a parcel by parcel basis is not possible. Because this district has been created largely as a tool and because its application will only be occasional, its similarity to a “floating zone” or “spot zone” is recognized; but, at the same time, any intent to create such zones is specifically rejected; and
(l) Open Space OS District. Primarily for the preservation of open space for recreation and scenic purposes and to protect steep slopes and watercourses through public and quasi-public ownership but including certain compatible private uses.
