1Buildings within a district adjacent to any residential use or district are subject to additional minimum building setbacks as defined in Subsection B-6-c.

2Buildings with heights in excess of 30 ft. shall provide 1 foot of additional setback for each foot of building height over 30 ft.

3Except as provided herein, minimum net site area and lot width requirements do not apply for lots within a unified commercial development, which is a development intended for three or more businesses, so long as the development has permanent cross-access, shared parking and access easements, in a form approved by the City Attorney or his/her designee, necessary to meet minimum parking and maneuvering requirements and any other applicable requirements. If there are conflicts between this exception and other requirements in the Zoning Ordinance pursuant to which a site would be required to meet or exceed the minimum net site area or minimum lot width requirements, this exception shall not apply.

4Except as provided herein, the setback for lots within a unified commercial development, which is intended for three or more businesses with permanent cross access and shared parking easements, shall be measured from the nearest public streets. If there are conflicts between this exception and other requirements in the Zoning Ordinance pursuant to which a site would be required to meet or exceed the minimum setbacks, this exception shall not apply.

B. DEVELOPMENT STANDARDS FOR COMMERCIAL DISTRICTS.

1. Substantial additions to or remodeling fifty percent (50%) or more of existing buildings shall be subject to Site Plan review.

2. Required yards fronting on a public street shall be entirely landscaped except for driveways and walkways. Parking and maneuvering areas shall not be permitted in required yard fronting on a public street.

3. A mobile home, recreational vehicle, or similar vehicle shall be prohibited as a facility for any commercial use permitted in this Ordinance except construction trailers and offices which are allowed while construction is being conducted on the site, or manufactured buildings that have staff-approved architectural treatments (i.e., stucco).

7. Screening standards shall be observed as follows:

a. All outdoor storage areas for materials, trash, equipment, vehicles or similar items shall be screened from view along all street frontages by a six (6) foot wall constructed of slump block, brick, or masonry with a stucco or mortar wash finish designed to match the main building on the site.

b. All loading, delivery and carwash service bays shall not front onto a public street and shall be screened from public view with at least a six (6) foot wall, constructed of brick, slump block, or masonry with a stucco or mortar wash finish, or a similar finish, designed to match the main building on the site.

c. The storage of materials, trash, equipment, vehicles, or other items within an enclosed storage area should not be substantially visible from adjoining streets or properties.

d. Dismantling, servicing or repairing of vehicles and/or equipment shall be within completely enclosed building or within an area enclosed by brick, block or masonry walls.

e. All outdoor refuse enclosures shall be located a minimum of 50 feet from any single-family, detached residential zoning district, or a minimum of 30 feet if a 30-foot wide landscape buffer is established and maintained between the enclosure and the single-family, detached residential zoning district along the entire length of the commercially designated property, as measured from the exterior wall of the refuse enclosure to the nearest residential property line.

8. Buildings with metal or steel exteriors shall be architecturally altered through the construction of veneers, facades, or other architectural treatments and installation of landscaping to minimize the extent of metal surfaces visible from the street.

9. Drive-through windows shall not face onto a public street. Stacking lanes shall be screened from the street with three (3) foot masonry walls or berms.
