10.746 General Design Requirements for Parking.
(1) The design provisions of this section are applicable to all new parking facilities, parking lot expansions, and to areas where existing parking facilities are excavated, including grinding, and re-installed. A pre-existing parking lot that is legally nonconforming to a standard in subsections (3), (4), (9), or (10) of this section and is improved with a surface pavement overlay only, without excavation of existing pavement, may remain nonconforming to that particular standard(s). All other provisions of this section are applicable to resurfaced parking lots.
(2) Conformity with Code. No building footprint or structure shall be enlarged more than 30 percent without the inclusion of additional parking spaces in conformance with the requirements of this code. The requirements of this code shall apply only to the additional parking necessitated by the change in use or building expansion.
(3) Final Certificate of Occupancy. No Final Certificate of Occupancy shall be granted to any structure until the parking areas are completed and ready for use.
(4) Department of Environmental Quality (D.E.Q.) Indirect Source Construction Permit. All parking areas, where applicable, shall be subject to review and approval by the Department of Environmental Quality.
(5) Off -Street Parking Redevelopment. Property owners shall be allowed to redevelop any portion of existing off-street parking areas for any one of the following, and in doing so may supply fewer off-street parking spaces than the existing mandated minimum; however, access for emergency vehicles must be retained.

(i) Bicycle parking;
(ii) Bus stops and pullouts;
(iii) Bus shelters;
(iv) Park and ride stations; and
(v) Similar facilities.
(6) Drainage. Adequate drainage shall be provided to dispose of the runoff generated by the impervious surface area of the parking area. Provisions shall be made for the on-site collection of drainage waters to eliminate sheet flow of such waters onto sidewalks, public rights-of-way, and abutting private property.
(7) Surfacing. All surfacing shall be consistent with the Medford Municipal Code parking lot specifications, Section 9.550. All parking, loading, driveway and vehicle maneuvering areas, including but not limited to: wheeled-vehicle sales lots, truck trailer parking areas, and on-site single-family residential driveways, etc., shall be paved and improved pursuant to the following minimum design requirements of this section.

Curb cuts shall be located not closer than five feet to a side lot line, except that a common access way to two adjacent properties (width not exceeding 45 feet) may be provided at the common lot line. Common access ways shall be encouraged in order to reduce the number of access points to streets. Access grades shall not exceed 15 percent and shall be graded to allow clearance to pass a standard American automobile 15 feet in length.
