A. 
Generally. No structure shall be erected, substantially altered, or its use changed unless permanent off-street parking and loading spaces have been provided in accordance with this chapter. In the I-95 and Downtown Revitalization Overlay Districts and the Integrated Business District, the special parking provisions described therein will apply unless noted otherwise for specific uses. Parking requirements are specified for particular uses in Subsection B of this section. Issuance of any building permits or use and occupancy certificates shall not be granted until a plot plan showing such off-street parking as is herein required is submitted and approved by the Zoning Administrator. The number of parking spaces required shall be based on the gross floor area of the use, excluding incidental storage, mechanical areas, preparation areas, and common areas such as public corridors, stairwells, and elevators.

The parking area shall be set back a minimum of five feet from collector road rights-of-way and 10 feet from arterial road rights-of-way. A landscape plan will be required and prepared by a licensed landscape architect and submitted to the Department of Planning and Community Development for review and approval.
(7) 
Common residential parking areas shall include access into adjoining properties.
(8) 
Two access points are required for more than 100 residential dwelling units and hotels with more than 100 rooms.
(9) 
The parking lot lighting shall be directed downward and not onto adjacent properties.

(11) 
Shared parking facilities may be allowed after reviewing the different uses within an individual building or adjacent buildings or properties located within 500 feet of the subject property’s boundaries based on a parking impact study provided by the developer(s) or owner(s) establishing that the estimated peak demand for parking required by the users will be satisfied due to differing hours of peak demand. If approved, a shared parking plan shall be enforced through written agreement and approved by the Zoning Administrator.
(a) 
Agreement for shared parking plan. A draft copy of the agreement between the owners of record shall be submitted to the Zoning Administrator, who shall forward a copy to the City’s legal counsel for review. After approval, the agreement shall be recorded in the land records of Harford County and a copy presented to the Zoning Administrator prior to issuance of a certificate of occupancy. The agreement shall:
[1] 
List the names and ownership interest of all parties to the agreement and contain the signatures of those parties;
[2] 
Provide a legal description of the land;
[3] 
Include a site plan showing the area of the parking parcel;
[4] 
Describe the area of the parking parcel and designate and reserve it for shared parking unencumbered by any conditions which would interfere with its use;
[5] 
Agree and expressly declare the intent for the covenant to run with the land and bind all parties and all successors in interest to the covenant;
[6] 
Ensure the continued availability of the spaces for joint use and provide assurance that all spaces will be usable to all participating uses;
[7] 
Describe the obligations of each party, including the maintenance responsibility for the parking area and any open space;
[8] 
Incorporate the parking impact study by reference; and
[9] 
Describe the method by which the covenant shall, if necessary, be revised.
(b) 
Change in use. Should any of the shared parking uses be changed, or should the Zoning Administrator find that any of the conditions described in the approved parking impact study or agreement no longer exist, the owner shall have the option of submitting a revised parking impact study and an amended shared parking agreement in accordance with the standards of this subsection, providing the number of spaces required for each use as if computed separately.
(c) 
Revocation of permits. Failure to comply with the shared parking provisions of this subsection shall constitute a violation of this chapter and shall specifically be cause for revocation of a certificate of occupancy.
(12) 
General requirements for parking lot/driveway design, construction, and maintenance are as follows:
(a) 
Parking areas shall be designed so that vehicles may exit such areas without backing onto a public street. This requirement does not apply to parking areas consisting of driveways that serve one or two dwelling units, although backing onto arterial streets is discouraged.
(b) 
Parking areas shall be designed so that sanitation, emergency, and other public service vehicles can serve such developments without the necessity of backing unreasonable distances or making other dangerous or hazardous turning movements.
(c) 
Parking areas shall be designed so that vehicles cannot extend beyond the perimeter of any such area onto adjacent properties or public rights-of-way. Such areas shall also be designed so that vehicles do not extend over sidewalks or tend to bump against or damage any wall, vegetation, or other obstruction. Bumper blocks or other means may be required to ensure this provision.
(d) 
Access to parking areas shall be designed so as not to obstruct free flow of traffic. There shall be adequate provision for ingress to and egress from all parking spaces to ensure ease of mobility, ample clearance, and safety of vehicles and pedestrians.
(e) 
Any required parking area shall be continually maintained in good, serviceable condition with striping clearly visible so as to be safe, attractive, and free of any hazard, nuisance or other unsafe condition. Commercial parking areas shall be maintained to ensure customer safety. All potholes or similar hazards shall be repaired promptly upon written notification by the City. In no case shall such conditions exist for more than 60 days.
B. 
Parking space requirements. When determination of the number of required parking spaces results in a fractional space, any fraction of 1/2 or less may be disregarded, while a fraction in excess of 1/2 shall be counted as one parking space. Unless otherwise provided, the following off-street parking space requirements shall apply:

8
(2) 
Minimum dimensions of 12 feet by 55 feet and overhead clearance of 14 feet from street grade are required.
(3) 
Loading and unloading areas shall be so located and designed that the vehicles intended to use them can maneuver safely and conveniently to and from public rights-of-way and complete the loading and unloading operations without obstructing or interfering with any public right-of-way, parking space, parking lot aisle or pedestrianway.
(4) 
No loading and unloading areas may be used to satisfy the area requirements for off-street parking, nor shall any portion of any off-street parking area be used to satisfy the area requirements for loading and unloading.
(5) 
Loading spaces shall be located at least 50 feet from any residential use, unless the loading space is totally enclosed within a building or screened by a hedge, wall, or solid board fence at least six feet in height.
D. 
Parking and loading space reduction. A request for a reduction in the number of required parking or loading spaces may be made by filing an application for a waiver with the Zoning Administrator. Upon receipt of an application for a parking or loading space waiver, a public hearing shall be scheduled before the Board of Appeals. A waiver or reduction of the parking and loading requirements in any district may be permitted by the Board of Appeals whenever the character or use of the building is such as to make full provision of the specific parking and loading requirements unnecessary, or where adequate community loading facilities are provided on site, or where, due to problems of access or to the size of the lot, the provision of the required loading spaces is impractical.
(1) 
In permitting such a waiver for new construction, the Board of Appeals must find the following:
(a) 
The requirements for parking and loading would result in particular or exceptional difficulties upon the owner of such property; and
(b) 
Such relief can be granted without substantial impairment of the intent or purpose of this section.
(2) 
In permitting such a waiver for existing buildings, the Board of Appeals must find the following:
(a) 
The proposed new use of the building would normally require fewer spaces than the prior use;
(b) 
The reduced number of spaces will be adequate to accommodate the proposed use; and
(c)
