2 Parking Space and Drive Aisle Dimension Requirements June 2011 What are your code s minimum dimension requirements for a standard parking space? Municipality Parallel Space Angle Space Are there any standard exceptions to these requirements? If so, please describe. What are the minimum dimension requirements for compact parking spaces? Do you allow compact parking spaces? Parallel Space Angle Space Is there a limitation on the percentage/ number of spaces that can be compact spaces? If so, what is that limitation? Hoffman Estates Length -25 ft Length -18 ft We allow 8.5 width for low turnover parking spaces in special conditions. We only allow parallel spaces on-street, not in parking lots. We do not specifically call out compact parking spaces. If a developer proposed compact spaces, we would possibly allow. Lake Zurich Length -20 ft (except handicapped) Length -20 ft (except handicapped) 20' may be reduced to 18' if landscaped area provided for overhang. Lincolnshire Width varies (8-10 ft) Length varies (19-26 ft) (0 and 90 degrees, per Lincolnshire Code) Width varies ( ft) Length 19 ft (30, 45 and 60 degrees, per Lincolnshire Code) Based on angle--see attached Yes. Lincolnshire does not have Code language regulating this type of parking spaces. However, if such spaces were to be proposed, they would be reviewed based on individual project, and likely approved. Northbrook Length -23 ft Length -20 ft Spaces in industrial district only need to be 8.5 x18, in downtown overlay spaces may be reduced to 8.5 x18 through design review process. 2

8 City of Highland Park Chapter 150, Article 8, Section (D) (D) Minimum Area and Spacing Requirements. The following are minimum requirements, and it shall be the responsibility of the property owner to maintain the facilities in such a condition as to be able to continue to meet these requirements. (1) Geometrics. All parking stalls and aisle dimensions shall have minimum dimensions as set forth in Figure 1. The "module" at any angle is the required dimension of two parked vehicles and the aisle between. Modules may be adjusted for overhang and interlock effects as detailed herein. When automobile overhang beyond an installed curb is included in the stall depth calculation, such overhang shall be considered as part of the parking stall and not for landscaping or setback purposes.

9 (2) Parking Table. The size and spacing specifications for required off-street parking facilities shall be taken from the diagram and table below: Angle (degrees) Stall Width Projection Vehicle Projection Aisle Typical Module Interlock Reduction Overhang Off-set (A) (A)* (B) (C) (D) (E) (F) (G) N.A. N.A. N.A N.A. 2 8 N.A. * Handicapped Stalls (see additional footnotes on next page) Notes: 1. Stall sizes are based on projections of parked vehicles. 2. Parallel parking stall lengths shall be Other angles may not be used except by permission of Director of Planning. 4. Offset (G) does not include curb or island width. (a) When curb dimensions exceed the overhang dimension (F), the module shall be increased accordingly. Off-sets at angled parking stalls shall be as per dimension (G). Interlock reductions (E) may only be taken where barriers and appurtenances extend into less than 10% of the parking stalls. Columns, pipes, light standards and other appurtenances may protrude into a non-interlocked module up to a maximum combined dimension of two feet (2"). (b) In facilities where the predominant use is low turnover parking (defined as at least 75% of the daily users parking for more than three hours), the stall width may be reduced to eight feet three inches (8'3"), with all other dimensions as shown in Figure 1. In open or enclosed parking structures or in facilities where a wheel stop or vehicle restraint system is provided in all stalls, the aisle may be reduced by one foot (1'), reducing the total module by a like amount. A maximum of 10% of a parking facility may be provided as compact stalls with a minimum width of seven feet six inches (7'6") where dimensional constraints such as walls, columns, or turning aisles exist. Designs with more than 10% of the capacity provided as compact stalls may not be employed except by permission of the Zoning Administrator.

10 (3) Turn Around Area. When only one (1) entry or exit is provided, all required off-street parking and loading facilities shall contain internal circulation or an adequate turn around area for the size of vehicles normally expected to use such facilities. (4) Sidewalks. In order to insure pedestrian safety, sidewalks of not less than three (3) feet in width, exclusive of vehicle overhang, are required to separate any driveway or parking area from a building. (5) Stacking Areas. When entry to a parking facility is controlled by gates, there shall be at least one entrance lane and gate for every 400 parking spaces provided. Adequate reservoir areas in addition to the service position shall be provided at all entrance lanes to eliminate queuing of vehicles on public property, including sidewalks. The space for each vehicle in the stacking area shall be a minimum of 9' by 20'. Ratio of Capacity to Number of Entrance Lanes Reservoir Areas 0 to 200 None 201 to 300 One vehicle 301 to 350 Two vehicles 351 to 400 Three vehicles (6) Required Stacking Spaces. (a) A Motor Vehicle Washing Facility shall provide a paved off-street parking area sufficient in size to provide the number of off-street parking spaces required in this Chapter as well as a minimum number of off-street stacking spaces equal to the product obtained by multiplying by 10 the maximum number of automobiles capable of being washed at any one time. (b) Similar off-street stacking spaces shall be provided for other drive-in uses as follows: drive-in window; window; and drive-in window. (i) (ii) (iii) Financial institutions five (5) spaces per Restaurants six (6) spaces per drive-in Other drive-in facilities four (4) spaces per

12 OFF-STREET PARKING. (A) Use Of Parking Facilities: Required off-street parking facilities shall be solely for the parking of vehicles of patrons, occupants (or their guests) or employees of such uses, or used in the business but not vehicles in excess of eight thousand (8,000) pounds and bearing a class designation of other than "A" or "B". Those vehicles greater than eight thousand (8,000) pounds which are used in the conduct of business, bearing a class designation of "D" or greater, shall be parked/stored in accordance with the applicable off-street parking and loading requirements for the zoning district in which they are located. Vehicle classifications are those found under the Illinois Motor Vehicle Law. State law reference 625 ILCS 5/3-813, 3-815, Unless otherwise specified in this chapter, off-street parking and loading facilities shall not be used for the sale, display, storage, repair, dismantling, or servicing of any vehicles, equipment, materials, goods, or supplies. However, emergency service required to start vehicles shall be permitted. (B) Design And Maintenance: It shall be the responsibility of the director of community development or his/her authorized designee, acting in the capacity of zoning administrator, to review plans for all parking lots over four (4) spaces to ensure compliance with this chapter and his/her approval must be obtained as part of site plan approval. 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 to traffic within and adjacent to parking areas, to topographical conditions, to runoff of stormwater, public convenience and safety, and in their appropriate relations to the proposed uses to be served. All traffic intersections and confluences must encourage safe and efficient traffic flow. (1) Parking Lot Design: The following are requirements for parking lot design: (a) (b) (c) (d) (e) (f) (g) Circulation aisles shall align with one another. Parking aisles shall not exceed four hundred fifty feet (450') in length so as not to encourage high speed and irregular traffic flow. Parking is prohibited along main circulation aisles. For uses with frequent drop off or pick up, such as daycare centers, churches and other uses as determined by the director of community development or his/her authorized designee acting in the capacity of zoning administrator, segregated drop off/pick up areas shall be provided. These areas should be designed so that they are segregated from the main circulation aisles. Smooth and efficient on-site circulation must be provided. All parking lots shall be landscaped in accordance with sections and of this chapter.

13 (2) Shared interconnects and shared driveways with adjoining properties shall be provided wherever feasible as determined by the director of community development or his/her authorized designee acting in the capacity of zoning administrator. Size: All parking stall and aisle dimensions except at certain entrances as stated in subsection (B)(13) of this section shall have the minimum dimensions, as set forth in figure 1 of this section. An automobile overhang may be included in stall depth calculations where such overhang does not extend beyond a required parking setback line or encroach upon a sidewalk. When an automobile overhang beyond an installed curb is included in the stall depth calculation, such overhang shall be considered as part of the parking stall for landscaping or setback purposes.
