§ 153.110. PARKING REQUIREMENTS.

The following provisions of this section and § 153.111 shall apply as noted, except as may be modified, supplemented or supplanted under the provisions of any particular zoning district.

(A) Off-street parking requirements. The purpose of this section is to minimize congestion of the public streets and to promote the safety and welfare of the public. Off-street parking is required as accessory to principal uses permitted in the district, and approval shall not be granted nor land uses authorized other than in conformity with such parking requirements.

(B) Definitions. For the purpose of this section and § 153.111, the following definitions shall apply unless the context clearly indicates or requires a different meaning.

CIRCULATION AREA. Driveways and other maneuvering areas (other than parking aisles) used for access to parking or loading areas or other facilities on the lot.

DRIVEWAY. The portion of the vehicle parking area that constitutes a travel lane for ingress-egress that is not part of the vehicle parking area.

GROSS FLOOR AREA. The total area of a building measured by taking the outside dimensions of the building at each floor level intended for any use.

LOADING AND UNLOADING AREA. That portion of the vehicle parking area utilized for accessing vehicles.

PARKING AREA. The portion of a lot that is used by vehicles for access, circulation, parking, and loading and unloading. This area comprises the total of circulation areas, loading and unloading areas, and PARKING AREAS (spaces and aisles).

PARKING AREA AISLES. The portion of the vehicle parking area consisting of lanes providing access to parking spaces.

PARKING SPACE. A portion of the vehicle parking area established or allocated for the parking of one vehicle.

USABLE AREA. In calculating the total number of required parking spaces, USABLE AREA shall mean the area devoted to the specified use (does not include such spaces as kitchens, restrooms, hallways and the like); the term SEAT shall also include each 30 inches of bench seating when individual seats are not provided.

USE. The purpose for which a building, lot or structure is arranged, designed, occupied or maintained.

(C) Requirements for off-street parking.

(1) Maintenance of existing parking. All off-street parking required by this section shall be established and improved before operation of the use or uses requiring such parking area may begin, and shall be maintained for the duration of such use.

(2) Existing off-street parking shall not be reduced or modified for any existing business except in instances where parking space allocations meet all requirements of these Zoning Regulations. Modifications to the parking allocation may be considered by the Planning and Zoning Commission in instances where the Institute of Traffic Engineer Standards further clarify the parking ratio or allocation for a business not specified herein.

(3) The use of off-street parking space for the storage of merchandise, vehicles for sale or rent, or for repair of vehicles, shall be expressly prohibited.

(4) When the use of any existing building, structure, or premises is changed to a new use, or the intensity of the use is increased through the incorporation of additional dwelling units, gross floor area, seating capacity, or other units of measurement specified for required parking or loading facilities, and which change of use or intensity creates a need for an increase in the total number of required parking spaces of 10% or 20 spaces, either with a single change or cumulative changes, subsequent to the effective date of this chapter, then parking and loading facilities as required shall be provided for the entire building, structure or premises. When such an increase in required parking is less than 10% cumulatively, the change of use or intensity is exempt from the requirements of this section.

(5) Required improvements shall be completed in accordance with these zoning regulations prior to commencement of the use or occupancy of the site.

(D) Location of required parking spaces.

(1) Residential uses. Required off-street parking for single family dwellings shall be provided on the same site as the building or use being served. Off-street parking for multiple-family dwellings or residences in PAD zoning districts may be provided in a parking area on or off the site not farther than 200 feet from an entrance to each dwelling unit it is intended to serve.

(2) Nonresidential uses.

(a) Required off-street parking shall be located on or off the site within 300 feet of the building or use it is intended to serve, the distance being measured from the nearest point of the building or use; provided, however, that parking facilities for sports assembly, public assembly for outdoor entertainment, sports and recreational activities, resorts and group camps, or similar uses, shall be located not farther than 1,300 feet from the nearest point of such building or use.

(b) The Planning and Zoning Commission may authorize off-premises parking including on-street parking within 300 feet of the associated business, as part of a development plan or proposal, in instances where use of the parking area is authorized on a long-term basis by the property owner and/or the public jurisdiction that administers public right-of-way.

(c) The Zoning Administrator may deny a request to use off-premises or on-street parking in instances where authorization may be on a temporary basis and/or if the proposed off-premises parking plan is not in the interest of the public health, safety and welfare. A decision to deny a development plan or proposal may be appealed to the Board of Adjustment.

(E) Methods of providing required off-street parking. Off-street parking may be achieved by any one or a combination of the following:

(1) Limited credit for space. One parking area may contain required spaces for several different uses, but except as otherwise provided in this section, the required space assigned to one use may not be credited to any other use.

(2) Combination of uses. Where there is a combination of uses on a lot, the number of automobile parking spaces shall be the sum of the requirements of the various uses. If, in the opinion of the Zoning Administrator, the uses would not be operated simultaneously, the number of automobile parking spaces shall be determined by the use with the highest parking demand.

(3) Shared parking. By securing the consent to use off-street parking facilities under another's ownership, which is not otherwise used or required during the principal operating hours of usage, that consent shall be in written form and a copy filed with the Town Zoning Administrator. The number of parking spaces may be reduced up to a maximum of 20% of the total spaces required. In the event the off-site spaces are or become no longer available, the owner shall provide additional parking to meet this requirement.

(4) Common areas. Provisions shall be made for maintenance of common service areas by a corporation, partnership, trust or other legal entity having the right to access or place a lien upon the individual lot owners for all necessary costs and/or expenses. A letter of maintenance responsibility will be required as part of the zoning clearance procedure.

(F) Dimensions and circulation.

(1) General dimensions. Each parking space shall contain a rectangular area at least 20 feet long and nine feet wide. Lines demarcating parking spaces may be drawn at various angles in relation to curbs or aisles, so long as the parking spaces so created contain within them the rectangular area required by this section.

(2) Compact spaces. In parking areas containing ten or more parking spaces, up to 20% of the parking spaces may contain a rectangular area of only seven and one-half feet in width by 15 feet in length. If such spaces are provided, they shall be conspicuously designated as reserved for small or compact cars only.

(3) Aisle widths. Parking area aisle widths shall conform to the following table, which varies the width requirement according to the angle of parking:

Parking Angle (Degrees)	Req. Aisle Width
	One-Way Traffic	Two-Way Traffic
0	13 ft.	19 ft.
30	11 ft.	20 ft.
45	13 ft.	21 ft.
60	18 ft.	23 ft.
90	24 ft.	24 ft.

(4) Wall. Where such areas are contiguous to a rural or residential district (except when separated by a public street), a solid wall six feet in height shall be installed on the district boundary line, which wall to be reduced to four feet in height within the front yard area of the abutting rural or residential district.

(5) Access. Space utilized for ingress and egress for a parking area shall be from a two-way driveway and shall not exceed 30 feet in width measured along the street frontage R.O.W. (right-of-way) and a minimum width of 24 feet and shall not constitute more than 25% of the total frontage of the parking area.

(6) Entrances and exits. Entrances and exits to parking lots and other parking facilities shall be provided only at defined entry and exit locations approved by the Development Services Department. Ingress and egress from parking areas shall not be located less than 30 feet from any intersection R.O.W.

(7) Passenger drop-off points. Drop-off points separated from street traffic and readily accessible without hazardous maneuvering, shall be provided in conjunction with the following uses: hotels, motels, hospitals and clinics, educational facilities with 50 or more pupils, daycare centers, religious facilities with 100 or more seats, transit terminals, major recreational facilities, commercial airports, public buildings and offices and financial services greater than 5,000 square feet of gross floor area.

(G) General design requirements.

(1) Unless no other practicable alternative is available, vehicle 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 no more than two dwelling units.

(2) Vehicle parking areas for all developments shall be designed so that sanitation, emergency and other public service vehicles can serve the developments.

(3) Every vehicle parking area shall be designed so that vehicles do not extend beyond the perimeter of the area onto adjacent properties or public rights-of-way.

(4) All lights used to illuminate parking spaces shall be installed pursuant to §§ 153.150 through 153.153. The lights shall be no greater than 18 feet in height.

(5) Requirements for handicapped parking and access are required pursuant to A.R.S. §§ 41-1492.01 et seq.

(H) Schedule of required off-street spaces.

(1) Use not listed. For a use not specifically listed, requirements shall be the same as those for the most similar use listed as determined by the Zoning Administrator.

(2) Fractional amount. In calculating the total number of required off-street parking spaces, fractional amounts are to be rounded to the nearest whole number (one-half shall be rounded to the next highest number).

(3) Parking for places of public assembly. For buildings used for public assembly, whether erected following the adoption of this chapter or converted subsequently for same, parking shall be provided as indicated in the requirements for off-street parking spaces on the following pages.
