§ 157.015  ESTABLISHMENT OF ZONING DISTRICTS.
   (A)   The city is hereby divided into the following zoning districts with the designations and purposes listed below.
   (B)   The districts included in this chapter are adopted for the promotion and protection of the public health, safety, morals and/or general welfare. The purpose of each district is to provide specific regulations for use of land and control of other land development features such as lot size, lot width and yards, maximum lot coverage, and height of structures. The purposes of each district is further defined as follows.
      (1)   R-12 Residential/Low Density.  These districts are composed primarily of areas occupied by or suitable for one-family dwellings on large lots, resulting in low density development. The district regulations are designed to protect the residential character of the districts by prohibiting commercial activities, and to encourage a suitable environment for family life.
      (2)   R-6 Residential/Medium Density.  These districts are composed primarily of areas occupied by or suitable for one-family dwellings at a medium density. The district regulations are designed to protect the residential character of the districts by limiting commercial activities, and to encourage a suitable environment for family life.
      (3)   R-5 Residential/Medium Density.  These districts are composed primarily of areas occupied by or suitable for either one-family or a mixture of one-family, two-family and multi-family dwellings in a medium density range. The district regulations are designed to encourage the construction of mixed single- and multi-family units, and to protect the residential character of the areas by limiting commercial activities, to encourage a suitable environment for family life, to prevent overcrowding of the land by requiring certain minimum yard and other open spaces for all buildings, to avoid excessive population density by requiring a certain minimum building site area for each dwelling unit, and to protect the abutting and surrounding areas by requiring certain minimum yard and area standards.
      (4)   R-4 Residential/High Density.  These districts are composed mainly of areas occupied by or suitable for high density multi-family uses located in proximity to business, service or employment centers. These districts may also contain public and semi-public uses to support high density residential development.  The district regulations are designed to encourage and protect the high density residential character of the districts by limiting the permitted uses primarily to dwellings and requiring certain minimum yard and area standards.
      (5)   B-1 Business/Neighborhood.  These districts are composed of land and structures occupied by or suitable for uses supplying retail goods and services to surrounding residential neighborhoods. Often located on a thoroughfare or near the intersection of two thoroughfares, these districts are small and conveniently located for the areas they serve. The district regulations are designed to permit the controlled development of the districts to protect the abutting and surrounding residential areas.
      (6)   B-2 Business/General.  These districts are composed of land and structures occupied by or suitable for uses supplying a wide range of retail goods and services. Usually located on a thoroughfare or highway or near the intersection of principal thoroughfares or highways, these districts are relatively large and within convenient distance of the area they serve. The district regulations are designed to allow commercial development while protecting the abutting and surrounding residential areas.
      (7)   B-3 Business/Downtown.  These districts are composed of land and structures occupied by or suitable for uses furnishing the wide range of retail goods and services required by residents of the regional trade area. Located at the convergence of the principal thoroughfares and highways, the downtown is the focus of commerce and administrative business of the trade area. The district regulations are designed to permit further development of the district for its purpose in a compact and convenient arrangement of uses and structures that are urban in character.
      (8)   I-1 Industrial/Light.  These districts are composed of land and structures occupied by or suitable for light manufacturing, wholesaling, warehousing, and similar uses. Uses located in these districts should have a minimum negative environmental impact (including, but not limited to noise, glare, and vibration) on adjoining properties. Located for convenient access to present and future thoroughfares, highways and railway lines, these districts are usually separated from residential areas by business districts or by natural barriers; if they are adjacent to residential areas, an artificial or natural separation is required. The district regulations are designed to allow a range of light industrial activities subject to limitations designed to protect nearby residential and business districts.
      (9)   I-2 Industrial/Heavy.  These districts are composed of land and structures occupied by or suitable for heavy manufacturing and related activities. Located for convenient access to present and future arterial thoroughfares, highways, and railway lines, these districts are usually separated from residential areas by business districts or natural barriers; if they are adjacent to residential areas, an artificial or natural separation is required. The district regulations are designed to promote the development of the districts for industrial use subject to conditions necessary for the mutual benefit of the uses and the city.
      (10)   P-H Public/Hospital.  These districts are designed to support the unique development needs associated with large scale health care institutions. Hospitals and related medical service offices, support commercial uses, and accessory parking facilities are compatible uses in these districts. When these districts adjoin residential areas, provisions are included to preserve the privacy and uses of dwelling units.
      (11)   R-E Residential Estate.  These districts are composed of land and structures occupied by or suitable for one family dwellings on very large lots. The regulations are designed to accommodate residential development opportunities for those who desire low density estate living in more remote or topographically difficult locations for urban development; and who are willing to assume the costs of providing many of their own services and amenities.  The regulations further are designed to minimize disruption to natural features such as steep slopes and unstable soils; and to protect the estate character of the district by prohibiting commercial uses and heavy traffic generators.
