(1) Materials and architectural features similar to those present on the front of the building shall be used on the side or rear facade.

Parking. Parking and parking lot design shall comply with the standards set forth below, in addition to the provisions of Chapter 1290, Off-Street Parking and Loading, and Section 1296.03, Landscaping Standards, of this Zoning Code. (1) No new parking lot shall be created, nor shall any existing parking lot be expanded in front of a building, unless the Planning Commission determines that parking in front of the building would be acceptable for either of the following reasons:
A. Front yard parking is required to maintain the continuity of building setbacks in the block while making efficient use of the site; or
B. Front yard parking is required for the purposes of traffic safety and to minimize driveway curb cuts where the new parking lot is proposed to connect with one (1) or more parking lots on adjoining parcels.
If the Planning Commission determines that a new parking lot must be created or an existing parking lot must be expanded, the parking lot shall be located to the rear of the building (unless the conditions set forth in paragraphs (f)(1)A. and B. hereof are satisfied), on the interior of the lots, accessed by means of common driveways, preferably from side streets or lanes. Such parking lots shall be small in scale where possible, and interconnected with commercial parking lots on adjacent properties. Cross-access easements for adjacent lots with interconnected parking lots shall be required, in language acceptable to the City Attorney. Common, shared parking facilities are encouraged, wherever possible.
(2) Parking located in front or on the side of a building shall be screened from the road with one (1) of the following: a thirty-six (36) inch decorative masonry or stone wall; a forty-eight (48) inch ornamental fence; or a thirty-six (36) inch evergreen hedge in accordance with Section
1296.03, Landscaping Standards.
(3) In order to maximize the amount of land area left for landscaping and open space, paving shall be confined to the minimum area necessary to comply with the parking requirements of
Chapter 1290, Off-Street Parking and Loading, of this Zoning Code.

(2) On every site involving new development or redevelopment, a landscape plan shall be submitted for review and approval. The landscape design shall complement the character of the downtown.
(3) Lots for apartment and non-residential uses shall balance the functional requirements of parking with the provision of pedestrian amenities. Transition areas between parking and civic, commercial or residential uses shall be designed with textured paving, landscaping and street furniture.
(h) Building Setback. Buildings shall be built at lot lines with no setbacks, or the average setback of other buildings on the block, as determined by the Planning Commission.
(i) Building Height. The minimum height of all buildings shall be two (2) stories and twenty-eight (28) feet. Both stories shall contain habitable commercial, office, or residential space.
(j) Building Mass.

(n) Mechanical Equipment. All air conditioning units, HVAC systems, exhaust pipes or stacks, elevator housing and satellite dishes and other telecommunications receiving devices shall be thoroughly screened from view from the public right-of-way and from adjacent properties, by using walls, fences, roof elements, penthouse-type screening devices or landscaping.
