In order to carry out the provisions and purposes of this title, the affected area of Sangamon County is divided into the following districts:

1. Agricultural Districts.
   A-1 Agriculture. Purpose: The A-1 agriculture district consists of areas where the soil, water, vegetal, topographical and other conditions are best adapted to the pursuit of agriculture. The district is designed to prevent the intrusion of nonagricultural land use which would hinder agricultural pursuits by removing prime farmland from production, causing congestion of public roads and creating conflicts between agricultural and nonagricultural uses. It is the intent of this title to allow maximum freedom of operation of agricultural uses and to preserve conditions suitable for agricultural pursuits. No nonagricultural uses shall be permitted in the A-1 district, except for those specified in Chapter 17.10.
2. Residence Districts.
   1. R-1 and R-1(A) Single-family Residence Districts. Purpose: The R-1 single-family residence district is designed to encourage and preserve low density neighborhoods within the county and to provide a suitable environment for activities associated with family life. This district is intended to be used primarily in areas where public facilities as well as public services such as fire protection are readily available. The R-1(A) single-family residence district provides for residential development of an intermediate density where both public sewer and public water are available.
   2. R-2 Single-family and Two-family Residence District. Purpose: The R-2 single-family and two-family residence district is designed to encourage and preserve medium density neighborhoods within the county and to provide a suitable environment for activities associated with family life. This district is intended to be used primarily in areas where public facilities such as sanitary sewer and public water as well as public services such as fire protection are readily available.
   3. R-3 General Residence District. Purpose: The R-3 general residence district is designed to accommodate a balanced mixture of single-family, two-family and multifamily housing with appropriate standards on density and the spacing of buildings. This district is intended to be used primarily in areas where public facilities such as sanitary sewer and public water as well as public services such as fire protection are readily available.
   4. RM-4 Manufactured Home District. Purpose: The RM-4 manufactured home district is created to meet the needs of persons utilizing manufactured homes as dwelling units and to provide for their accommodation in manufactured home parks. Single-family homes on lots that meet the bulk requirements of the R-1 district or the provisions of Section 17.06.050 are also permitted. This district is intended to be used primarily in areas where public facilities such as sanitary sewers and public services such as fire protection are available.
3. Planned Unit Development District. Purpose: The purpose of the PUD planned unit development district is to encourage the creation of a new and more desirable man-made environment. Under the PUD classification, the developer of ten (10) or more acres of land in Sangamon County is offered an opportunity to stretch for the best possible arrangement and interrelationships of streets, land use and buildings on the land through the planning, designing and layout process. The more traditional design limits imposed by zoning district use and bulk requirements and by the separate requirements of the land subdivision regulations are removed for the PUD developer. He is thus given a free hand to work towards the achievement of goals and objectives of the county comprehensive plan and to develop layouts that will result in a wider range of settings for a contemporary way of life.
4. Office and College District. Purpose: The office and college district is designed to provide areas that permit a mixture of residential uses and compatible service uses. This district allows uses permitted in the R-3 district as well as uses such as health care facilities, higher education facilities, offices, and accompanying uses. While allowing some intensive uses, the O district is intended to exclude uses that increase noise and traffic and hence are offensive to patient care, educational, and residential uses.
5. Business Districts.
   1. B-1 Neighborhood Business District. Purpose: The B-1 neighborhood business district is established to provide basic goods and services for the residents of the surrounding neighborhood. It provides for small scale operations which will satisfy the needs of the local consumer.
   2. B-2 Retail Business District. Purpose: The B-2 retail business district is designed to provide for a wide range of retail sales and service uses, excluding such goods and services which are durable or industrial in character. Uses permitted in the B-1 district are also permitted.
   3. B-3 General Business District. Purpose: The B-3 general business district is created to permit a wide spectrum of commercial uses. Permitted uses in this district are inclusive of all uses allowed in the B-1 and B-2 districts and also include goods and services which are durable or industrial in character and semi-commercial industrial services that support the retail functions in nearby major commercial centers. The B-3 district is also designed to accommodate highway oriented services. Uses permitted in the B-2 district are also permitted.
6. Industrial Districts.
   1. I-1 Restricted Industrial District. Purpose: The I-1 restricted industrial district is intended to allow a compatible mixture of selected industrial uses and commercial uses. Permitted uses in this district are inclusive of all uses allowed in the B-1, B-2, and B-3 districts, except for adult uses, along with light industrial uses that are in accordance with the applicable performance standards. Dwelling and lodging units are not permitted except for watchman's quarters. Only one watchman's quarters is allowed per business.
   2. I-2 General Industrial District. Purpose: The I-2 general industrial district is established to allow a wide range of both commercial and industrial uses. Permitted uses in this district are inclusive of all uses allowed in the B-1, B-2, B-3, except for adult uses, and I-1 districts and all permitted industrial uses that are in accordance with the applicable performance standards. The I-1 district is designed to accommodate the essential heavy and industrial uses. Dwelling and lodging units are not permitted except for watchman's quarters. Only one watchman's quarters is allowed per business.

The location and boundaries of the above zoning districts are established as set forth on the Zoning District Map for the Springfield Urbanized Area (1"=800') and the individual township zoning district maps (3"=1 mile), which are adopted and are incorporated into this title.

When uncertainty exists with respect to the boundaries of the various districts shown on the zoning district maps, the following rules shall apply:

1. District boundary lines are either the centerlines of railroads, highways, streets, alleys, easements or streams, or are coterminous with lot lines and tract lines or such lines extended unless otherwise indicated;
2. Where a boundary line is shown as being located a specific distance from a street or road line or other physical feature, this distance shall control;
3. In unsubdivided property, unless otherwise indicated, the district boundary line shall be determined by the use of the scale contained on such maps;
