The off street parking and loading provisions of this chapter shall apply as follows, subject to the restrictions set forth in section 13-12-3 of this chapter:

   A.   Accessory off street parking and off street loading facilities shall be provided as required by the regulations of this chapter for all uses and structures established in each district after the effective date hereof. However, where a building permit has been issued prior to the effective date hereof, and construction is begun within ninety (90) days after such effective date and diligently prosecuted to completion, parking and loading facilities as required for the issuance of said building permit may be provided in lieu of any different amounts required by this chapter.

   B.   When the intensity of use of any structure or premises is increased through the addition of dwelling units, gross floor area or seating capacity parking and loading facilities for the addition shall be provided in the amount specified herein.

   C.   Whenever the existing use of a structure shall hereafter be changed to a new use, parking or loading facilities shall be provided as required for such new use. However, if the said structure was erected prior to the effective date hereof, additional parking or loading facilities are mandatory only in the amount by which the requirements for the new use would exceed those for the existing use, if the latter were subject to the parking and loading provisions of this chapter.

   D.   The design and engineering for all new or modifications to existing parking and loading facilities shall be approved by the village engineer prior to construction. (Ord. G-687, 10-23-2001)

Nothing in this chapter shall be deemed to prevent the voluntary establishment of off street parking and loading facilities to serve any existing uses or structures, provided that all regulations herein governing the location, design, and operation of such facilities are followed. (Ord. G-687, 10-23-2001)

   A.   Existing Parking Facilities: Accessory off street parking facilities in existence on the effective date hereof and located on the same lot as the structure or use served shall not hereafter be reduced below the requirements for a similar new structure or use under the provisions of this chapter.

   B.   Location: After the effective date hereof, all off street parking spaces shall be located on the same lot as the building, structure or use of land served; however, off street parking spaces may also be located on a lot other than the lot on which the building, structure or use of land served is located, provided that said spaces are also within five hundred fifty feet (550') walking distance of such building, structure, or use of land. All off street parking spaces required for single- family residences shall be located on the same lot as the residence, provided that no required spaces may be located in any front or side yard.

   C.   Size And Aisles: Each required off street parking space shall have a width and length, exclusive of access drives or aisles, ramps, columns, or office and work areas in accordance with standards set forth below. Enclosed parking spaces shall have a vertical clearance of at least seven feet (7'). Each required off street parking space shall open directly upon an aisle or driveway of a width and design in accordance with standards set forth below:

   MINIMUM STANDARDS OF PARKING SPACES, AISLES AND PARKING BAYS FOR PARKING ACCESSORY TO NONOFFICE USES

 

 

 

    MINIMUM STANDARDS OF PARKING SPACES, AISLES AND PARKING BAYS FOR PARKING ACCESSORY TO OFFICE AND HOTEL USES

 

 

   D.   Timing Of Construction: All required off-street parking shall be constructed in accordance with the design criteria of this chapter and shall be improved and ready for use as a condition of occupancy for the structure, issuance of additional permits or use of land. However, the property owner may request approval from the Director of Development Services, to initially construct no less than seventy five percent (75%) of the required parking as a condition of occupancy with the remaining required spaces to be set aside and constructed when the parking demands for the site as determined by the village, require the construction of the set aside parking spaces. Prior to occupancy, a written covenant agreeing to construct the set aside parking spaces shall be submitted to the village for review and approval. Once approved, this document shall be filed for recording in the office of the county recorder of deeds and shall run with the parcel of land.

   E.   Access: All off-street parking facilities shall be provided with appropriate means of vehicular access to a street in accordance with regulations set forth below:

      ACCESS DRIVEWAYS FROM STREETS TO OFF-STREET PARKING AND LOADING SPACES

      1.   Width of driveways (measured at the lot line adjoining a street):

         a.   Residential Uses: Not less than nine feet (9') wide or more than twenty feet (20') wide.

         b.   Nonresidential Uses:

            (1)   Not less than twelve feet (12') wide or more than twenty two feet (22') wide for a one-way driveway.

            (2)   Not less than twenty two feet (22') wide or more than twenty five feet (25') wide for a two-way driveway serving twenty (20) or fewer parking spaces or one loading berth.

            (3)   Not less than:

               (B) Twenty four feet (24') wide or more than forty four feet (44') wide for a two-way driveway (2 lanes out and 1 lane in) with a median, serving more than twenty (20) parking spaces or two (2) or more loading berths.

      2.   Radius connecting street pavement edge and driveway edge:

         a.   In Residential Districts: Not less than two feet (2').

         b.   In All Other Districts: Not less than fifteen feet (15').

      3.   Angle at intersection of a driveway and street: The acute angle formed at the intersection of driveway and street pavement edges shall be not less than sixty degrees (60°). The required turning angle for a vehicle entering or leaving a driveway shall not exceed ninety degrees (90°).

      4.   Spacing between separate driveway entrances on a lot (measured center to center at the lot line adjoining a street): no less than forty percent (40%) of the length of the lot line adjoining the street, or four hundred feet (400'), whichever is less.

      5.   On corner lots, spacing between driveway entrance and right-of- way line of an adjacent intersecting street (measured from the nearest edge of the driveway pavement at its intersection with the street pavement to the nearest right- of-way line, extended, of an adjacent intersecting street): no less than twenty percent (20%) of the length of the lot line adjoining the street being entered.

   F.   Use: Accessory off-street parking facilities, as accessory to specific uses listed in this chapter, shall be solely for the parking of automobiles of patrons, occupants or employees. When bus transportation is provided for patrons, occupants or employees of a specific establishment, additional open or enclosed off-street parking spaces for bus parking on the premises shall be provided in accordance with all other regulations set forth in this chapter.

   G.   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 one-half (1/2) or less may be disregarded while a fraction in excess of one-half (1/2) shall be counted as one parking space.

   H.   In Yards: Off-street parking spaces, open to the sky, in nonresidential districts, may be located in required interior side yards and rear yards, no less than ten feet (10') from the nearest lot line, except a parking area containing four (4) or more parking spaces shall be not less than forty feet (40') from an adjoining residence district boundary; provided, however, that:

   J.   Collective Provision: Off-street parking facilities for separate uses located in a principal building on a single parcel may be provided collectively if the total number of spaces so provided is not less than the sum of the separate requirements for each such use and provided that all regulations governing location of accessory parking spaces, in relation to the use served, are adhered to. In addition, any parcel of land that has excess parking beyond what is required by this chapter may allocate excess parking capacity to any parcel or use that is directly contiguous to it under a shared parking arrangement if it meets the applicable requirements of this chapter. Such arrangement must be in written form with notification provided to the village.

   K.   Control Of Off-Street Parking Facilities: In cases where parking facilities are permitted on a lot other than the lot on which the structure or use served is located, a covenant running with the land must be recorded in the office of the recorder of deeds of DuPage County, Illinois, on the lot upon which the accessory off-street parking is located which prohibits any other use on that lot, and a copy of the recorded covenant certified by the office of the recorder of deeds of DuPage County, Illinois, shall be deposited with the Director of Development Services. The covenant shall not be released until such time as either one of the following conditions occurs:

      1.   The structure on the lot containing the principal use is removed and the principal use terminated.

      2.   Another lot of the required size within the required distance is properly developed and used for the required accessory off-street parking in place of and in lieu of the initial lot used for accessory off-street parking with the same requirements, covenants, and conditions attaching to such substitute accessory use lot as approved by the same authority as required for approval of such initial lot.

   L.   Employee Parking: Parking spaces required on an employee basis shall be based on the maximum number of employees on duty or residing, or both, on the premises at any one time.

   M.   Repair And Service: Except in cases of emergency, no motor vehicle repair work or service of any kind shall be permitted in off-street parking areas. No gasoline or motor oil shall be sold or services performed in conjunction with any accessory parking facilities unless such facilities are located within a completely enclosed structure, in which case gasoline and motor oil may be sold within such structure to the users of such facilities, provided that no sign thereto is visible from outside the structure and provided further that all gasoline pumps shall be effectively screened from view of streets and residence districts.

   C.   Lighting: Illumination of an off street parking area shall be arranged so as not to project direct rays of light or glare into any roadway or adjacent property. Intensity of illumination of parking areas shall be in accordance with the village of Oak Brook public works construction standards. All lighting for business and office uses adjacent to residential districts shall be extinguished or reduced in intensity, not later than thirty (30) minutes after the close of business of the use being served.

   D.   Disposal Of Storm Water: Adequate provision shall be made for the management of storm water in accordance with village standards so that such water shall not flow into adjacent property or onto or across sidewalks in a quantity or manner that would be detrimental thereto or inconvenient to persons using the sidewalks.

   E.   Permanent Curbing: Continuous permanent concrete curbing conforming to the village of Oak Brook public works construction standards shall be provided adjacent to all driveway, loading and parking pavement associated with nonresidential uses.

   F.   Striping And Traffic Circulation: Parking spaces shall be delineated by a single white or yellow line. For one-way movements along aisles and driveways, direction of movement shall be indicated by pavement markings or directional signs or both as determined by the village.

   H.   Parking Structures:

      1.   Architecture/Design: All exterior walls of such structures, which are visible from adjacent roadways, shall be finished with a material to maintain a "common architectural character", as defined in section 13-8-4 of this title, with the principal building. Maintaining common architectural character between the parking structure and the principal building(s) shall be judged in terms of: building form and materials; the pattern, size, shape, and number of window openings; the glazing or screening of window openings; and surface treatments such as cornices, moldings, reveals and sills.

      2.   Lighting: Parking structures with light standards on the top floor of the structure shall be located in the center aisle of the deck and shall be of appropriate design and scale. Low profile lighting should be used around the perimeter of the parking structure and all internal/external light sources shall be properly screened from view to minimize glare on adjacent property.

      3.   Setbacks: For any new parking structure that abuts a Residence District, the setbacks shall be ten feet (10') plus two feet (2') for every one foot (1') in height above grade, up to a maximum setback of one hundred feet (100') for the parking structure. (Also see landscape setback requirements in Chapter 18.) (Ord. G-687, 10-23-2001; Ord. G-12611, 10-22-2024)
