§ 152.17  DISTRICTS DEFINED.
   The districts identified above are described as follows:
   (A)   Residence districts.  Five districts, R1, R2, R3, RS, and MHP are established for residential use in conformity with the types of neighborhoods which have occurred and are likely to develop in the areas so designated in the zone map.  The districts differ primarily with respect to requirements of lot size, building ground floor area, and the number of families which may be housed in one building.  The specific requirements for each residence district are shown in Appendix A following this chapter.  Certain non-residential  special exceptions may be permitted in these districts, as described more fully in Appendix G and Appendix H following this chapter.  A brief description follows:
      (1)   Rl.  This is a single-family dwelling district which includes the major part of the jurisdictional area inside the city where the established pattern of development indicates stable development of that character.  The minimum lot and building areas required in this district recognize current desirable residential construction practices.
      (2)   R2.  This district permits single- and two-family dwellings.
      (3)   R3.  This district permits single- two-, and multiple-family dwellings. The R2 and R3 Districts include the more densely built-up sections of the city close to the central business area where a number of such uses now exist and others are likely to occur through the conversion of existing large residential structures. Minimum lot area and building area requirements in the R3 District are the lowest contained in this chapter.
      (4)   RS.  Included in this district is the large part of the jurisdictional area outside the city subject to residential use where no clear pattern of development is evident.  While the district will be used primarily for single-family dwellings,  two-family and multi-family buildings will be permitted on a density-of-use basis, with the minimum lot size being increased for each additional dwelling unit included in a building.  The RS requirements as to minimum size of lots are greater than those specified for the other residence districts.
      (5)   Mobile Home Park.  This district provides suitable locations for higher density concentration of single-family dwellings characteristic of mobile home parks and promotes quality design, landscaping, and standards of building and grounds maintenance.  The regulations of this section shall complement and be applied in addition to the State Board of Health Regulations HSE 21-R, and amendments thereto.
   (B)   Commercial districts - Four districts, Cl, C2, C3, and C4, are established to meet the specific requirements for the several classes of business uses needed to give adequate service throughout the jurisdictional area as related to present and future development. Single-, two-family, and multi-family dwellings are permitted uses in all of the commercial districts except the C3 and C4, which are designated for the shopping center and service center types of development.  All residential uses in the commercial districts are subject to the requirements of Appendix A following this chapter.  The specific requirements for business uses in these districts are given in Appendices B, C, and D following this chapter.  For special exceptions permitted in the commercial districts see Appendices G and H following this chapter.  A brief description of the commercial districts follows:
      (1)   Cl.  This district is designed and located in neighborhoods to accommodate the primary shopping and service needs of the locality.  Although limited in area occupied, these districts are important to the economic welfare of the community in placing "convenience" and "impulse" goods shops close to the consumer. The local business uses defined in § 152.26 are permitted in all commercial districts.
      (2)   C2.  This is a general business district providing for all types of business and service uses including warehouse and storage facilities as well as some light industrial operations.
      (3)   C3.  This district is provided to meet the need for retail shopping facilities in planned shopping centers in the sections of the jurisdictional area where no clear pattern of business use now exists.  It is proposed that each such business center be established on a single, well-planned site of at least six acres in area to accommodate the shopping needs of a neighborhood.  No specific parcel of property is designated for this purpose in the zone map, but one shopping center may be established within l,400 feet of a C3 symbol shown in the zone map.
      (4)   C4.  This district is provided to meet the need for special business centers to accommodate travelers at important locations along arterial streets in the jurisdictional area.  Types of business use are limited in this district.
   (C)   Industrial districts.  Three districts, Il, I2 and IR, are established to meet the present and future needs of the jurisdictional area for industrial development.  Residential uses will be excluded from the Il and I2 Districts.  Where permitted, residential and business uses will conform to the requirements set forth for them in Appendices A through D respectively, which follow this chapter, respectively.  The specific requirements for industrial uses in these Districts are given in Appendices E and F, which follow this chapter. For special exceptions in the industrial districts see Appendices G and H, which follow this chapter. A brief description of the industrial districts follows:
      (1)   I1.  This district incorporates a substantial part of the existing industrial developments and is provided for industrial operations utilizing enclosed space for storage, fabricating, and manufacturing.  It includes the lands in the jurisdictional area which are best suited to this type of industrial use.
      (2)   I2.  This district provides for general industrial operations utilizing both enclosed and unenclosed space for storage, fabricating, and manufacturing.
      (3)   IR.  This district is reserved for planned industrial parks which are also permitted in this district, while business uses are excluded.
   (D)   Flood plain district.  The FP District is established to meet the need for controlling the development of lands which have excessively high water tables or which are subject to frequent and periodic floods.
