In order to carry out the purposes and provisions of this ordinance, the Village of Lemont is hereby divided into the following districts:

A.

Residential Districts. The residential districts ("R districts") are primarily for residential land uses and for other selected uses that are deemed compatible with residential environments. The R districts are intended to maintain and promote a variety of housing types within the Village.

1.

R-1 Single-Family Detached Residential District. This district is intended to provide very low density areas for relatively large single-family detached homes on lot sizes of three acres or more.

2.

R-2 Single-Family Detached Residential District. This district is intended to provide areas of very low density and low density, with single-family detached dwellings on lot sizes of 40,000 square feet or more.

3.

R-3 Single-Family Detached Residential District. This district is intended to provide areas for low-density, single-family detached dwellings on lot sizes between 20,000 and 40,000 square feet.

4.

R-4 Single-Family Detached Residential District. This district is intended to provide regulations for both some of the older established areas of the Village and the majority of newer areas annexed into the Village, and to provide areas for low- and medium-density, single-family detached dwellings on lot sizes of 12,500 square feet or more.

5.

R-4A Single-Family Preservation and Infill District. This district is intended to regulate the height, building coverage, and impervious surface coverage of residential dwelling units in the older established neighborhoods of the Village. Specifically, the district's restrictions are intended to prevent the overcrowding of land, ensure proper living conditions, assure the adequate provision of light, air and open spaces, and to foster and preserve the nature, character, and quality of existing neighborhoods, while providing property owners opportunities for infill development on vacant lots or redevelopment of lots with existing structures. In particular this district is intended to prevent the further proliferation of structures that do not conform to the general height, bulk, and scale of existing structures.

6.

R-5 Single-Family Attached Residential District. This district is intended to provide medium-density areas for single-family attached dwellings, i.e. duplexes, two-family detached dwellings, and town homes.

7.

R-5A Single-Family Detached and Attached Residential District. This district is intended to provide medium to high-density areas for single-family detached dwellings and single-family attached dwellings (duplex only).

8.

R-6 Multi-Family Residential District. This district is intended to provide medium and high-density areas for single-family attached and multi-family dwellings: duplexes, two-family detached dwellings, town homes, apartment buildings and condominium buildings.

B.

Business Districts. The various business districts ("B districts) are intended to maintain and promote a variety of commercial activity within the Village. The district formerly known as B-2 Historic Central Business District has been superseded by the downtown district, and the provisions for this district have been placed in a separate chapter of this ordinance—see chapter 17.09.

1.

B-1 Office/Retail Transitional District. This district is intended to provide an environment suitable for retail, service, and office establishments. The intensity of the uses is less than the B-3, and site layout is less oriented toward the automobile than the B-3.

2.

B-3 Arterial Commercial District. This district is intended to accommodate a wide range of retail, service, and commercial uses where patrons arrive by vehicle rather than other modes of transportation. This district is meant for the highest intensities of commercial use.

3.

B-4 Commercial Recreation. The B-4 regulations are intended to provide for the orderly, compatible development of land and the maximum recreational potential of the land.

C.

Manufacturing Districts. The manufacturing districts ("M districts") are designed to provide for the establishment of a full range of industrial and allied activities, and to mitigate any negative effects of these activities on other land uses.

1.

M-1 Light Manufacturing District. This district is intended to provide an environment suitable for industrial activities that require a pleasant and nuisance-free environment and be compatible with adjacent land uses. Additionally, the M-1 district is intended to provide an environment suitable for certain office and research activities that do not create appreciable nuisances or hazards. This district may be located adjacent to R districts, and thus its provisions include special yard setbacks and screening requirements.

2.

M-2 General Manufacturing District. This district is designed to accommodate those industrial activities that have moderate land use intensity and are located in areas relatively remote from residential and prime retail development.

3.

M-3 Heavy Manufacturing District. This district is designed to accommodate relatively large, self-contained and isolated areas intended to be used for industrial activities having potentially moderate to high land use intensity.

4.

M-4 Mineral Extraction District. This district is designed to regulate the conservation, development, management and appropriate use of all the natural resources of such areas for compatible multiple purposes, and protecting the health, safety and general welfare of the people, as well as the natural beauty and aesthetic values, in the affected areas. Within the Township there are many valuable mineral deposits that must be protected against the premature encroachment of urban development. These natural resources, including deposits of sand, gravel, stone, clay, coal, and other minerals represent an important consideration in the economic and physical development of the Township. Because of the unique aspects involved, in the mineral operations and the potential reuse of the land once the minerals are extracted, a separate zoning classification is established.

D.

Other Districts.

1.

DD Downtown District. The downtown district ("DD district") is established to promote a compatible mixture of commercial, cultural, institutional, governmental, and residential uses in a compact, pedestrian-oriented, traditional village center consistent with the Comprehensive Plan and other documents, such as the Downtown Master Plan, that the Village may adopt from time to time. Additionally, the DD district is intended to maintain and enhance the historic, community, architectural, and aesthetic qualities unique to the downtown area.

2.

INT Institutional District. The institutional district ("INT district") is designed to provide an environment for land uses of a civic, educational, governmental, recreational, and religious nature. It is also intended to provide an environment for institutional group living.

3.

OL Open Lands District. The OL Open Lands District is intended to recognize the existence of major open lands and recreational areas in the Village. The Open Lands District is intended for the designation and protection of open lands, farms and parks as well as public recreational facilities, including both active and passive recreation areas and certain ancillary uses.

A.

Adoption. The locations and boundaries of the zoning districts established by this Zoning Ordinance are shown on the Village of Lemont Zoning Map ("the Zoning Map"), which—together with all notations, references and other information shown on the map—is hereby adopted and incorporated into this Zoning Ordinance.

B.

Maintenance. The Village of Lemont Zoning Map is maintained by the Planning and Economic Development Director. In case of any dispute regarding the zoning classification of any property subject to this ordinance, the Zoning Map maintained by the Planning and Economic Development Director governs.

C.

Zoning District Boundaries. Where uncertainty exists with respect to boundaries of the various zoning districts as shown on the Zoning Map, the following rules apply:

1.

Where zoning district boundaries are indicated as following streets, alleys, railroad right-of-ways, bodies of water or extensions thereof, such boundary lines are to be construed as centerlines of the streets, alleys, railroad right-of-ways, bodies of water or extensions.

2.

Unless otherwise dimensioned, boundaries are construed to follow lot lines.

3.

Streets, alleys, or other public right-of-ways that have been vacated will be construed to fall in the same zoning district as the lots abutting both sides of the street, alley or right-of-way involved. If the lots abutting each side of the street, alley or right-of-way were classified in different zoning districts before the vacation, the centerline of the street, alley, or right-of-way shall be construed as the boundary between the zoning districts.
