OFF-STREET PARKING AND LOADING REQUIREMENTS

37-1201.1: - SCOPE OF REGULATIONS.

The off-street parking and loading provisions of this chapter shall apply as follows:

A.

Off-Street Parking and Loading Facilities: For all buildings and structures erected and for all uses of land established after the effective date of this chapter, or any amendment hereto, accessory off-street parking and loading facilities shall be provided for each particular type of permitted or conditional use. Where a building permit has been issued prior to the effective date of this chapter, provided construction is begun within ninety (90) days after the effective date thereof and diligently prosecuted to completion (completion to be accomplished within eighteen (18) months from the effective date of this chapter), parking and loading facilities in the amounts required for the issuance of said building permit may be provided in lieu of any different amount required by this chapter.

B.

Increased Parking and Loading Facilities: Where the intensity of use of any building, structure, or premises shall be increased through the addition of dwelling units, gross floor area, seating capacity, or other units of measurement specified herein for required parking or loading facilities, additional parking and loading facilities as required herein shall be provided for such increase in intensity of use only.

C.

New Off-Street Parking and Loading Facilities: Whenever the existing use of a building or structure shall hereafter be changed to a new use, parking and loading facilities shall be provided as required for such new use. If the said building or structure was erected prior to the effective date of this chapter, additional parking or loading facilities are mandatory only in the amount for the new use.

D.

Existing Off-Street Parking and Loading Facilities: Accessory off-street parking and loading facilities in existence on the effective date of this chapter, or any amendment hereto, and located on the same zoning lot as the building, structure or use served, shall not here after be reduced below, or if already less than, shall not be further reduced below the requirements for a similar new building or use under the provisions of this chapter.

E.

Floor Area Determination Adjustment: The amount of gross floor area for land uses appearing in Section 37-1203 of this chapter, items 1-1 through 1-7 inclusive of this chapter, utilized for determining the number of off-street parking spaces required shall be reduced in the amount by which the building places for such land uses show space devoted to atriums, auditoriums and cafeterias which are not open to the general public. Any reduction in required off-street parking spaces provided herein shall be based upon final architectural plans and specifications.

F.

Damage or Destruction: For any building containing a conforming use, legal conditional use, or legal nonconforming use which is in existence on the effective date of this chapter, and which building is subsequently damaged or destroyed by fire, collapse, explosion, or other cause, such building may be constructed, reestablished, or repaired provided off-street parking and loading facilities in an amount equivalent to that maintained at the time of such damage or destruction shall be restored or continued in operation. In no case, however, shall it be necessary to restore or maintain parking and loading facilities in excess of those required by this chapter for equivalent new uses or construction.

G.

Submission of Plot Plan and Plat of Survey: Any application for a building permit, or for a zoning certificate where no building permit is required, shall include therewith, a plot plan and an up to date plat of survey drawn to scale and fully dimensioned, showing off-street parking and loading facilities to be provided in compliance with this chapter. The plan shall show:

1.

The use of the building, structure, or parcel of land;

2.

The number of dwelling units, gross floor area, design capacity, estimated number of employees, or other units of measurement specified herein for determining the number of off-street parking spaces or loading berths required by the ordinance; and

3.

The arrangement, character, extent, width, grade, and location of all parking facilities shall be considered in relation to existing and planned streets; to reasonable circulation for traffic within and adjacent to parking areas; to topographical conditions and to runoff of stormwater; and public convenience and safety. No building, entrance permit, or zoning certificate shall be issued until the plot plan showing all required off-street parking and loading facilities is approved by the Director, Department of Economic Development and Planning.

H.

Permissive Off-Street Parking and Loading Facilities: Nothing in this chapter shall be deemed to prevent the voluntary establishment of off-street parking or loading facilities to serve an existing use of a building, structure or parcel of land provided that all regulations governing the location, design, and control of such facilities are adhered to.

When off-street parking or loading facilities are established, they may be decreased only when the facilities remaining will be at least equal to, or exceed the off-street parking or loading requirements resulting from application of the standards of this chapter to the entire use of the building, structure, or parcel of land as modified.

I.

Parking Area Design: It shall be the responsibility of the Director, Department of Economic Development and Planning, to review and approve plans for all parking lots containing more than four (4) spaces located less than forty feet (40′) from a residence district line. Upon approval of the plans, the Director, Department of Economic Development and Planning shall issue a zoning certificate for such parking area.

The arrangement, character, extent, width, grade and location of all parking areas shall be considered in relation to existing and planned streets; to reasonable circulation for traffic within and adjacent to parking areas; to topographical conditions and to the runoff of stormwater; and public convenience and safety. All parking areas including entrances and exists shall be designed in accordance with the "off-street parking chart," Section 37-1204, of this chapter.

J.

Accessible Parking: All uses except single-family detached or attached dwellings shall be required to provide off-street parking spaces for disabled persons in accordance with the standards established by the State of Illinois.

K.

Time of Construction; Off-Street Parking and Loading Facilities: Off-street parking and loading facilities, as required by this chapter, shall be constructed at the time of erection, establishment, alteration, or enlargement of any building, structure, or use of land. No occupancy certificate shall be issued by the Director, Department of Economic Development and Planning, until the required parking and loading facilities have been installed.

37-1202.1: - GENERAL REQUIREMENTS.

A.

EXEMPTION: When the application of the off-street parking provisions specified in Section 37-1203 of this chapter results in a requirement of not more than three (3) spaces on a single zoning lot in any business, office research, or industrial district, such parking spaces need not be provided where the building is unmanned; however, where two (2) or more uses are located on a single lot, only one (1) of those shall be eligible for the above exemption.

B.

LOCATION: All required off-street parking spaces including aisles and driveways shall be located on the same zoning lot (principal lot) as the building or use to which they are accessory, or on a contiguous lot which bears a zoning classification allowing parking as a permitted use and which is under the same ownership or possession as the principal lot. Where there are particular difficulties, or if the public safety and/or public convenience would be better served by a location other than on the same lot or on a contiguous lot, the Director, Department of Economic Development and Planning, acting upon specific application, may authorize an alternative location. All off-street parking spaces including aisles and driveways shall be subject to the following conditions:

1.

For a single-family dwelling of Categories 1-1 and 1-2 of Section 37-1203 of this chapter, if only one (1) of the required parking spaces is provided within a garage, the other required parking space may be located on the garage access driveway and may intrude into a required front yard but may not be located on a driveway turnaround. If none of the required spaces are provided within a garage, however, the required spaces shall not be located in a required front or side yard.

2.

For a single-family dwelling, Category 1-2 of Section 37-1203 of this article, the additional required one-half (½) parking space may be permitted contiguous to a local street subject to the approval of the Director, Department of Economic Development and Planning. Such parking spaces shall be located entirely within the development and may be located within the adjacent travel way of the street. Parking stalls shall be oriented at right angles to the travel way and shall be not less than twenty feet (20′) in depth and nine feet (9′) in width.

3.

Required parking space shall be located on the same lot as the use to which they are accessory or on land under the same ownership or control as that of the principal use. In this case, such required spaces shall be located within three hundred feet (300′) walking distance of a building entrance to the use that the spaces serve. In the case of a collective provision of parking spaces, as provided in Section 37-1202.1 of this article, such land shall be in the ownership of not less than one (1) of the participants in the collective provision, and such required space shall be located within three hundred feet (300′) walking distance of a building entrance to the use that such spaces serve.

4.

Off-street parking spaces, open to the sky, may be located in any required yard in any zoning district where such parking is not inconsistent with the zoning provisions of that district. Enclosed buildings and carports containing off-street parking spaces shall be subject to the applicable yard requirements in all districts.

5.

As an integral part of any planned development, where the design of a retail or business use has an orientation toward pedestrian or bicycle traffic which can be justified by appropriate documentation, a reduction in the number of required off street parking spaces may be granted of up to fifteen percent (15%) of the number of parking spaces otherwise required by the strict application of this chapter.

C.

CONTROL OF OFF SITE PARKING FACILITIES: In cases where required off site parking facilities are permitted on land other than the zoning lot on which the building or use served is located, such facilities shall be in the same ownership or possession as the zoning lot occupied by the building or use to which the parking facilities are accessory. Such ownership or possession may be either by deed or other instrument, the term of such instrument to be determined by the County Board, subject to a minimum of thirty (30) years.

D.

SIZE AND CONFIGURATION: Where the public safety or public convenience would be better served, the Director, Department of Economic Development and Planning, acting upon a specific application, may authorize modifications in all zoning districts for nonresidential and nonsingle-family residential uses as follows:

1.

Compact car facilities where allowed shall be limited to twenty-five percent (25%) of the spaces required for the site.

2.

The minimum stall size for compact car facilities shall be not less than eight and one-half feet (8½′) in width and not less than fifteen feet (15′) in depth.

3.

All compact car facilities (areas) shall be appropriately marked by signs designating those spaces as "For Compact Cars Only."

E.

OFF-STREET PARKING CHART: All other requirements as to parking stall and aisle width shall be as or set forth or interpolated from Section 37-1204, "Off-Street Parking Chart," of this article.

F.

ACCESS: Access to parking areas along collector/arterial streets shall be designed, located and controlled pursuant to the Arterial Highway Development Policies and Standards for DuPage County, adopted by resolution of the County Board.

All areas providing for off-street parking facilities shall open directly upon an aisle or driveway not less than nine feet (9′) wide for single-family, and twelve feet (12′) wide for all others, or such additional width and design as shown in the "off-street parking chart," Section 37-1204 of this chapter. Where there are practical difficulties; where public safety convenience would be better served; or where due cause is shown, modification may be granted by the Director, Department of Economic Development and Planning, for lots of record existing on the date of application of this chapter.

G.

COLLECTIVE PROVISION: Off-street parking facilities for separate uses may be provided collectively if the total number of spaces is not less than the sum of the separate requirements for each such use for those uses that have the same or overlapping hours of operation. For those uses which have different hours of operation with no overlap, the number of parking spaces shall be equal to the greatest requirement of any group of uses in operation at the same time. The Director, Department of Economic Development and Planning, shall have the discretion to determine when such reduction in required parking is justified based on appropriate documentation.

H.

COMPUTATION: When determination of the number of off-street parking spaces required by this chapter results in a requirement of a fractional space, any fraction of less than one-half (½) may be disregarded, while a fraction of one-half (½) or more, shall be counted as one (1) parking space. Where parking spaces are required on an employee basis they shall be based on the maximum number of employees on a shift (duty) at any one (1) time.

I.

UTILIZATION: Except as may otherwise be provided for the parking of trucks where a conditional use has been granted, required accessory off-street parking facilities provided for uses listed in Section 37-1203 of this chapter shall be solely for the parking of passenger automobiles in operating condition by patrons, occupants, or employees. No vehicle repair work except emergency service shall be permitted in association with any off-street parking facility.

J.

DESIGN AND MAINTENANCE:

1.

Permit Required: The creation of new off-street parking facilities and the expansion of existing off-street parking facilities for all nonresidential uses shall require the issuance of a permit from the Department of Economic Development and Planning, prior to such creation or expansion of parking facilities.

Plan: Except for residential uses, the design for parking lots or areas shall be subject to the approval of the Director, Department of Economic Development and Planning, in accordance with standards approved by the County Board.

3.

Character: Accessory parking spaces may be open to the sky, or enclosed in a parking structure.

4.

K.

EXCEPTIONS: All required off-street parking spaces and their appurtenant aisles and driveways (size of space and aisles) shall be provided on the same lot as the use for which the parking is provided. Areas provided for off-street parking spaces shall not be encroached upon or reduced in any manner except upon the granting of an exception by the County Development Committee of the County Board. Exceptions may be granted in the following instances:

1.

Shared Ride/Car Pooling Programs: Increasing the number of passengers per motor vehicle, decreases parking demand, e.g., employer sponsored van pooling, car pooling and subscription bus service. Utilization of these programs may warrant a reduction of required parking.

To qualify for van pooling, car pooling or subscription bus service, the petitioner shall submit evidence to the County Development Committee of the County Board that their van pooling, car pooling or subscription bus service program meets the requirements of this chapter.

a.

Shared Ride/Subscription Bus Service Program: An exception to reduce required parking by up to ten percent (10%), based on substantiated projections reducing parking demand, may be granted for any business, office or industrial building or complex containing not less than fifty thousand (50,000) square feet of gross floor area, where the petitioner has instituted or proposes to institute a shared ride/subscription bus service program which meets the following requirements:

(1)

The petitioner is participating or shall participate in an appropriate van pooling/subscription bus service program established under the provisions of the County Board of DuPage County.

(2)

Petitioner will obtain for lease to qualified employees, vans, buses, or other high passenger capacity vehicles, for the purpose of providing transportation of additional passengers.

(3)

Petitioner will operate or hire vans, buses or other high passenger capacity vehicles to provide exclusive or nonexclusive commuter transportation of employees from residential areas, train stations or other transit terminals.

(4)

Petitioner shall promote "third party" employee owned/leased and operated vans, buses or other high passenger capacity vehicle for the purpose of providing transportation of additional passengers.

b.

Car Pooling Program: An exception to reduce required parking by up to ten percent (10%), based on substantiated projections reducing parking demand, may be granted for any business, office or industrial building or complex containing not less than fifty thousand (50,000) square feet of gross floor area, when the petitioner has instituted or proposed to institute a car pooling program which meets the following requirements:

(1)

Car pooling program shall be the specific responsibility of a designated individual or department.

(2)

Program shall provide an active matching service using manual or automated matching of addresses and providing employees with potential car pools (passive matching alone such as bulletin boards is not acceptable).

(3)

Program shall endeavor to register all existing and all new employees.

(4)

Program shall actively promote car pooling to employees through newsletter posters and other media.

2.

Transit Facilities: The availability of rapid rail and scheduled bus service can decrease the parking demand in certain instances. To qualify for permissible reductions in parking space requirements because of close proximity to transit rail or bus transit services, the Petitioner shall submit evidence to the County Development Committee of the County Board that their business location meets the general guidelines of DuPage County as follows:

a.

An exception to reduce required parking by up to ten percent (10%) based on substantiated projections (ridership) reducing parking demand, may be granted for any residential subdivision or planned development of ten (10) dwelling units or more, office, business or industrial building or complex located within one-half (½) mile of any commuter rail station or other recognized transit station.

b.

An exception to reduce required parking by up to five percent (5%) based on substantiated projections (ridership) reducing parking demand, may be granted for any residential subdivision or planned development of ten (10) dwelling units or more office, business or industrial building or complex located within one-quarter (¼) mile of any regularly scheduled bus route with service during peak commuting hours.

3.

Reserved Land Area for Parking: All business, office or industrial buildings or complexes containing not less than fifty thousand (50,000) square feet of gross floor area where the petitioner is considering instituting shared ride/subscription bus service programs and/or car pooling program shall reserve adequate land area consistent to the requirements of this chapter to provide for the required off-street parking in case any one (1) of the above programs or any other similar programs ceases to operate.
