(Ord. 2021-05-15, passed 5-3-2021)

   (A)   Zoning District Map. The districts and their boundaries are as shown upon a zoning district map entitled "Village of Carol Stream Official Zoning Map" approved by the Mayor and Village Board. The Zoning District Map, properly attested to, shall be kept on file with the Village Clerk.

   (B)   District boundaries. When uncertainty exists with respect to the boundaries of the various districts shown on the zoning map and made a part of this UDO, the following rules shall apply.

      (1)   District boundary lines shall be on the lines of railroads, highways, streets or easements or the boundary lines of sections, quarter sections, divisions of sections, tracts or lots, or such lines extended unless otherwise indicated.

      (2)   In areas not subdivided into lots and blocks, whenever a district is indicated as a strip adjacent and parallel to a street or highway, the depth of such strips shall be in accordance with the dimensions shown on the maps measured at right angles from the centerline of the street or highway, and the length of frontage shall be in accordance with dimensions shown on the maps from sections, quarter sections or division lines in centerlines of streets, highways or railroad rights-of-way unless otherwise indicated.

      (3)   Where a lot held in one ownership and of record on the effective date of this UDO is divided by a district boundary line, the entire lot shall be construed to be within the less restricted district; provided that, this shall not apply if it increases the frontage of the lot by more than 25 feet required in the less restricted district.

   (C)   Zoning of streets, easements, public ways, waterways and railroad rights-of-way. All streets, easements, public ways, waterways and railroad rights-of-way, if not otherwise specifically designated, shall be deemed to be in the same zone as the property immediately abutting upon such streets, easements, public ways, waterways and railroad rights-of-way. Where any of the above rights-of-way serve as district boundaries, the zoning of such areas, unless otherwise designated, shall be deemed to be the same as that of the abutting property up to such centerline.

(Ord. 2021-05-15, passed 5-3-2021)

   Any area annexed to the village after the effective date of the adoption of this UDO shall, upon such annexation, be automatically zoned R-1, being defined as the most restrictive zone within this UDO, unless such area is zoned to a different zoning district, approved by the Village Board in accordance with the terms of an annexation agreement.

(Ord. 2021-05-15, passed 5-3-2021)

   (A)   General purpose of Residence Districts. Residence zoning districts are established, designed, and intended to provide a comfortable, healthy, safe, and pleasant environment in which to live and to:

      (1)   Provide appropriately located areas for residential development that are consistent with the Comprehensive Plan;

      (2)   Ensure adequate light, air, privacy, and open space for residents;

      (3)   Provide for a variety of neighborhoods with a range of housing types with varying characters and patterns of development;

      (4)   Protect neighborhoods from the harmful effects of excessive noise, traffic congestion, and other potential adverse impacts; and

   (B)   Estate Residence and Community Facilities District - R-1. (See Figure 16-3-4(B))

      (1)   Purpose. The R-1 District is established to provide and preserve areas for large lot single-unit detached dwellings as well as public amenities and complementary uses and activities such as places of worship, schools, and parks. The R-1 District shall be considered the highest restrictive district under the provisions of this UDO.

      (2)   Dimensional standards.

 

   (C)   Traditional Residence District - R-2. (See Figure 16-3-4(C))

      (1)   Purpose. The R-2 District is established to provide and preserve areas for residential neighborhoods with single-unit detached dwellings on lots comparable in size to original residential areas in the village.

      (2)   Dimensional standards.

   (D)   Suburban Residence District - R-3. (See Figure 16-3-4(D))

      (1)   Purpose. The R-3 District is established to provide and preserve areas for residential neighborhoods with single-unit detached dwellings on lots that are smaller in size than Traditional Neighborhood (R-2) District lots.

      (2)   Dimensional standards.

 

   (E)   Multiunit Residence District - R-4. (See Figure 16-3-4(E) )

      (1)   Purpose. The R-4 District is established to provide and preserve areas for higher density single unit attached dwellings and multiunit dwellings, such as condominiums, apartments, and senior housing developments in a single building or complex setting.

      (2)   Dimensional standards.

 

 

 

(Ord. 2021-05- 15, passed 5-3- 2021; Ord. 2021-09-45, passed 9-20-2021; Ord. 2022-09-39, passed 9-6-2022)

   (A)   General purpose of Business Districts. Business zoning districts are established, designed, and intended to provide a comfortable, healthy, safe, and pleasant environment in which to shop, dine, obtain various services, and to:

      (1)   Accommodate retail, commercial, service, and mixed uses needed by Carol Stream residents, businesses, visitors, and workers;

      (2)   Maintain and enhance the village's economic base and provide shopping, entertainment, restaurant, service and other nonresidential uses close to where people live and work;

      (3)   Create suitable environments for various types of business uses and protect them from the adverse effects of incompatible uses;

      (4)   Allow flexibility to encourage redevelopment and improvements to existing businesses; and

      (5)   Help ensure that the appearance and operational impacts of business uses do not adversely affect the character of the areas in which they are located.

   (B)   Town Center District - B-1. (See Figure 16-3-5(B))

      (1)   Purpose. The B-1 District is established to foster the growth and development of the village's "Town Center". The intent of this district is to provide for a variety of retail, office, service, residential, and cultural amenities in a central setting. While visitors are likely to access the B- 1 district by vehicle, bicycle and pedestrian facilities and circulation within the district are prioritized.

      (2)   Dimensional standards. Setbacks in the B-1 District shall be as established through the Planned Development and Gary Avenue Corridor Review Processes.

 

 

   (C)   Neighborhood Business District - B-2. (See Figure 16-3-5(C))

      (1)   Purpose. The B-2 District is established to provide and preserve areas that offer access to goods and services that residents and the general public need on a day-to-day basis. The intent of this district is to provide neighborhood-scale business uses without negatively impacting quality of life due to noise, traffic, or other issues related to high intensity business uses.

      (2)   Dimensional standards.

 

   (D)   General Business District - B-3. (See Figure 16-3-5(D))

      (1)   Purpose. The B-3 District is established to provide and preserve areas along highly visible and accessible road corridors that provide for a broad range of retail, wholesale, and service uses. Because of the scale and access requirements of uses in this district, they often cannot be compatibly integrated within the Town Center or Neighborhood Business Districts. Development at district boundaries must provide a compatible transition to uses outside the district.

      (2)   Dimensional standards.

 

(Ord. 2021-05-15, passed 5-3-2021; Ord. 2022-01-04, passed 1-3-2022)

   (A)   General purpose of Office, Service, and Industrial Districts. Office, service, and industrial zoning districts are established, designed, and intended to provide a healthy and safe environment in which to work and to:

      (1)   Maintain and enhance the village's economic base and provide employment opportunities;

      (2)   Preserve, protect, and promote employment-generating uses;

      (3)   Minimize potential negative impacts of office and industrial development on adjacent business and residential areas; and

      (4)   Help ensure that the appearance and operational impacts of office, service, and industrial developments do not adversely affect the character of the areas in which they are located.

   (B)   Office and Service District - O-S. (See Figure 16-3-6(B))

      (1)   Purpose. This district is established to provide and preserve areas for a wide range of office and service uses including research and development, total senior life care communities, office-flex, and large employment facilities such as those in a planned office campus or headquarters development. This district also accommodates limited supporting commercial uses as a means to support daily needs for employees within the district.

      (2)   Dimensional standards.

 

   (C)   Industrial District - I. (See Figure 16-3-6(C))

      (2)   Dimensional standards.

 

(Ord. 2021-05-15, passed 5-3-2021 ; Ord. 2022-01-04, passed 1-3-2022)

   (A)   All provisions of the UDO, to the extent that they do not conflict with the standards delineated in this section, shall remain in full force and effect for all properties subject to the provisions of this section.

   (B)   The standards found in this section shall be used by property owners, developers, village staff members, the Plan Commission and the Village Board during the design and review of development and redevelopment proposals within the overlay districts. These standards and criteria complement and add to those contained within the village's Comprehensive Plan, Gary Avenue Corridor Plan, the UDO and other land use regulations. In the event of conflict between regulatory ordinances, those contained in this section shall take precedence over all others.

   (C)   Gary Avenue and North Avenue Corridor Overlay District - GAC and NAC. (See Figure 16-3-7(C))

      (1)   Purpose. The Gary Avenue and North Avenue Corridors and the development within them are major factors influencing the visual and environmental quality of the village. At full development, the Corridor will contain the village's Town Center, other retail nodes, significant industrial and employment concentrations, public institutions, recreational facilities and residential development. Due to the intensity of these land uses, Gary Avenue and North Avenue represent the heart of the village, as well as a prominent image to those passing through the community. The purpose of the Gary Avenue and North Avenue Corridors is to:

         (a)   Create a unified, harmonious and high-quality visual environment throughout the Gary Avenue and North Avenue Corridors, thereby identifying them as special areas with a unique identity within the village and the region;

         (b)   Promote high-quality design through improved development standards within the Corridors. These standards, which govern site planning, building design, and landscaping will enable the village to enhance what otherwise might result in aesthetically and economically lower quality strip development;

         (c)   Foster a distinctive and positive image for the village and for the Gary Avenue and North Avenue Corridors which function as principal gateway into the village; and

         (d)   Protect and enhance wetlands and other significant natural resources through use of careful site design, protective easements, sensitive alignment and design of roadways and utilities, incorporation of natural features, landscaping and massing of trees.

      (2)   Dimensional standards. The dimensional standards of the underlying zoning district shall apply unless otherwise specified in § 16-5-16.

(Ord. 2021-05-15, passed 5-3-2021)

   (A)   Generally. Unless variations are granted pursuant to the variation provisions of this UDO, or unless site development allowances are granted through the Planned Development process as provided in Article 16-7, all new buildings shall conform to the bulk regulations established in this UDO for the district in which each building is located, and no existing building shall be enlarged, reconstructed, structurally altered, converted or relocated in such a manner as to conflict with the bulk regulations in this UDO for the district in which such buildings shall be located.

   (B)   Maintenance of yards, courts, and other open spaces. The maintenance of yards, courts, and other open spaces and minimum lot area legally required for a building shall be a continuing obligation of the owner of such building or of the property on which it is located, as long as the building is in existence. Furthermore, no legally required yards, courts or other open space or minimum lot area allocated to any building shall, by virtue of change of ownership or for any other reason, be used to satisfy yard, court, other open space or minimum lot area requirements for any other building.

   (C)   Location of required open spaces. All yards, courts and other open spaces allocated to a building or group of buildings shall be located on the same zoning lot as such building or group of buildings.

   (D)   Required yard for existing buildings. No yards on or hereafter provided for a building existing on the effective date of this UDO shall subsequently be reduced below, or further reduced below if already less than the minimum yard requirements of this UDO for equivalent new construction.

   (E)   Calculating dimensions.

      (1)   Yards.

         (a)   The required front yard setback shall be measured as the shortest distance between the building and the front property line.

         (b)   The required side yard or rear yard setback shall be measured by the shortest distance between the building and the lot line.

      (2)   The vertical distance measured from the sidewalk level or its equivalent established grade opposite the middle of the front of the building to the highest elevation of the roof in the case of a slant or flat roof; to the deck line of a mansard roof; and to the mean height level between eaves and ridge of a gable, hip or gambrel roof; provided that, where buildings are set back from the street line, the height of the building may be measured from the average elevation of the finished lot grade at the front of the building (see Figure 16-3-8 (F)(2)).

      (2)   Where a use exists on the effective date of this UDO and is classified as a special use, it shall be considered to be a lawful special use. Property granted such lawful special uses prior to the effective date of this UDO shall continue to have such uses and the use of the property shall be restricted to such special use and to such conditions under which the special use was granted. Additions or alterations to existing buildings or land improvements for expansion of lawful special uses shall be in accordance of this UDO.

   (E)   Only one principal structure, along with permitted accessory uses, shall be constructed upon a single subdivided lot or an unsubdivided parcel of land unless approved as a planned development in accordance with Article 16-7 of this UDO.
