New Development. The requirements of this chapter apply to all new buildings, structures and uses established in all zoning districts.

Expansion of Residential Development. The requirements of this chapter apply whenever additional dwelling units are added to an existing building or use.

Expansion of Non-Residential Development. If an addition is proposed to a building; an additional building is proposed for a lot; or if an expansion is proposed to an existing parking lot, the existing and expanded parking lot shall comply with the provisions of this chapter.

Change of Use. The requirements of this chapter apply to a change of use of an existing building or lot.

Existing Parking and Loading Areas. Existing required parking and loading areas may not be used to satisfy required off-street parking or loading areas for new or expanded buildings, structures or uses. Existing parking and loading spaces must be maintained and may not be reduced as long as the main building, structure or use remains, unless an equivalent number of spaces are provided elsewhere as permitted by this chapter.

Parking Spaces Required. Off-street parking spaces are required as specified in the table below.

Rules for Computing Requirements.

Parking Area Design and Construction.

One driveway opening is permitted to a lot from any street frontage provided that access is not otherwise controlled or restricted.

On corner lots one (1) driveway is permitted per street frontage provided that no off-street parking areas are located in the sight triangle area as described by this code.

A second driveway opening on the same street frontage is permitted for a lot in the A, RE and RR districts, provided that the lot area is one (1) acre or greater.

All residential driveways except those in the A and RE districts must be constructed with materials that create a hard surface, such as asphalt pavement or concrete. In the A and RE districts, gravel may be used for driveway surfacing.

All multi-family dwellings and apartment communities abutting arterial or collector streets as identified in the Growth Management Plan must comply with the commercial and industrial driveway standards of Section 425.040.

The minimum width of a single car driveway shall be ten (10) feet and the minimum width of a two-car driveway shall be eighteen (18) feet, measured at the property line.

Attached single-family and multiple-family dwellings should be served by a common access drive whenever possible and curb cuts must be minimized.

Individual driveways leading from a street to an attached garage must be of sufficient depth to ensure that parked vehicles do not overhang the sidewalk or public street. The distance between the sidewalk and the garage must be at least twenty (20) feet.

If concrete material is utilized on a driveway that is constructed in accordance with Section 425.030D, then the driveway and driveway approach shall utilize the Kansas City Metro Materials Board (KCMMB) 4K concrete material specification.

No residential driveway shall encroach upon, or be located within, a sight triangle.

General Performance Standards.

Standards for Right Turn Lanes and Tapers. Right turn lanes and tapers are required when:

Driveway Profiles. Driveway profiles must be determined based upon the grade of a two-way, one-way or divided commercial driveway and shall not exceed two percent (2%) for a minimum distance of twenty-five (25) feet from the edge of the pavement.

Driveway Spacing. Driveways shall be spaced in accordance with the minimum intersection spacing established by the American Public Works Association.

Number of Driveways per Parcel.

Corner Clearance. All direct-access driveways must be constructed so that the point of tangency of the curb return radius closest to a signalized or stop sign-controlled intersection is at least one hundred twenty (120) feet from the curb face of the intersecting street. Using a fifteen-foot driveway radius, the edge of the driveway throat must be one hundred thirty-five (135) feet from the curb face of the intersecting street. The driveway radius may not compound with the intersection corner radius.

Driveway Width. Except for dual driveways approved by the Director of Public Works, the width of the driveway throat may not exceed thirty-five (35) feet in width.

Failure to Comply. Failure to comply with any of the requirements of this chapter will be grounds for disapproval of the proposed plan or application for a building permit.

Applicability. The accessible parking standards of this section apply to all new parking lots for nonresidential uses and multi-family dwellings.

Spaces Required. Accessible parking spaces are required as specified in Chapter 11 of the International Building Code.

Layout and Design.

Applicability. Off-street loading spaces must be provided on the same lot as any new or expanded use, building, structure or part thereof that is involved in the receipt or distribution of materials, merchandise or other items by motor vehicle. Off-street loading spaces must be located and configured to avoid undue interference with public use of streets, alleys and walkways. No part of any vehicle may extend into a public right-of-way while being loaded or unloaded.
