All public or private parking areas and parking spaces shall be designed and laid out to conform to the minimum standards required by this Chapter and in accordance with the minimum standards for parking lot design as follows:
A. Minimum dimensional standards for parking lot designs are stated in "EXHIBIT 4, Minimum Standards for Standard Vehicles."
1. The minimum unobstructed interior width of a two-car private residential garage shall be twenty (20) feet. The minimum unobstructed depth of the stalls must be twenty (20) feet for the first stall and may be sixteen (16) feet for the second stall.

Surfacing: All parking lots, service drives, vehicle storage areas, and vehicle sales lots shall be paved and constructed to meet the City of Horseshoe Bend Standards, for base course and asphaltic concrete mat thickness; curbs and gutters where applicable; utilizing the appropriate traffic index.

D. Within the commercial zones, storage yards must be enclosed by a six (6) foot high, solid fence and may not be located in front of the main building. All areas must obtain approval from the City Engineer.
E. Grading: Except parking areas for single-family and two-family dwellings, parking areas shall be graded to prevent storm water runoff from crossing the sidewalk or from running onto adjacent properties or rights-of-way.
F. Bumper: All parking areas shall be provided with a substantial wheel restraint which will prevent cars from encroaching upon abutting private and public property or overhanging beyond the designated parking stall dimensions, except that the requirements of this subsection may be waived by the City Council for proper cause.
G. Bumper Overhang: When the City Council approves parking stall dimensions that allow bumper overhang onto a sidewalk or landscape strip, the parking stall dimension may be reduced two feet (2') in length if two feet (2') in width is added to the required sidewalk or landscape strip. Bumper overhang shall not damage landscaping.
H. Landscaping and Screening: All parking and storage areas (except those in conjunction with single family residences) including vehicle sales areas, truck parking areas, bus parking areas and service drives shall meet the following standards:
1. Along all streets there must be provided a continuous landscape area in accordance with the following standards:
a. The City Council shall require street trees with a minimum size of two inch (2") caliper in the landscape area.
b. Shrubs, lawn or other ground cover approved by the City Council shall be installed in all landscape areas. Landscape plants shall not include plastic or other artificial materials. The use of rock mulch shall be allowed at the discretion of the City Council. Only natural colored rock mulch shall be allowed with no patterning of the material.
c. All landscaped areas shall be provided with an underground irrigation system.
2. A minimum five (5) to six (6) ft. high solid screen shall be provided when a parking lot is adjacent to residential land uses. This screen may include fencing, walls and/or landscape combinations that will provide a dense barrier.
3. A minimum of five percent (5%) of the parking lot area, including drives, shall be landscaped with interior planters. Perimeter required landscaping shall not constitute part of the percentage. The City Council may approve a transfer of all or part of the required interior landscaping to other areas of the site.
4. Existing healthy trees should be retained as approved by Zoning Administrator and be considered in the design and grading of the property.
5. The Zoning Administrator may grant up to a ten percent (10%) reduction in the required number of parking spaces in order to preserve an existing tree(s).
6. The Zoning Administrator may grant up to a ten percent (10%) reduction in the required number of parking spaces in order to preserve an existing tree(s).
I. Clear Vision Triangle: A clear vision triangle shall be observed in regard to all visual barriers including all vegetation (except deciduous trees pruned at least eight (8) ft. in height above the sidewalk and fourteen (14) feet above the roadway, walls, signs, vehicles, solid fences or other sight obstructions exceeding three (3) feet in height. As shown in Exhibit 7 below.
J. Lighting: Any lights provided to illuminate any public or private parking area or vehicle sales area shall be so arranged as to reflect the light away from any abutting or adjacent residential land use zone or residential use.
K. Marking: All parking spaces shall be substantially marked in compliance with the provisions of this Title. The edge of a service drive shall be marked when bordered by garages that are setback from said service drive.
L. Ingress and Egress: Ingress and egress of parking structures shall be designed with due regard for visibility and safety.
M. Pedestrian Access: The development shall provide sidewalks and crosswalks that completely link, parking areas, buildings, open spaces and adjacent pathways. Sidewalks shall be at least four feet (4') wide, sited and illuminated to provide safe passage and observation of the pathway route. Sidewalk crossings of service drives shall be provided and clearly distinguished from the service drive.
1. Service drives and parking lots shall allow public access to places of public use and/or interest.
2. Service drives that serve more than forty (40) dwelling units will be designed based upon the standards of this Title and by a traffic plan prepared by a traffic engineer, submitted to and approved by the City Engineer and the Zoning Administrator for the interior roadway and parking system. The required transportation plan shall include the following information: The adequacy of approach streets and highways to accommodate development traffic; the need to expand or modify existing facilities; the locations and design of development driveways; pedestrian and bicycle facilities; consideration for service/emergency vehicular movement; safety for vehicular and pedestrian traffic; livability of the residential environment; economy of land use, construction and maintenance; and recommended street layout and dimensional standards. This requirement may be waived when it can be shown by the applicant that no section of on-site roadway will exceed two hundred and forty (240) vehicles per day.
O. Utility Location: Residential projects, that at a later date may be subdivided, should place utilities in the roadway or in easements parallel and next to the roadway. Projects that are later subdivided and do not comply with this recommendation may be subject to significant reconstruction and relocation costs.
P. Safety: As a means to improve traffic safety and to improve the visual quality of an area, the number of driveway intersections with public or private roadway in residential projects shall be minimized. Use of parking courts, alleys and common driveways is strongly encouraged. (Ord. 232, 4-14-2010)
