c.    High quality development and urban design standards that maintain a sense of history, human scale, and pedestrian-orientation.

18-102.  Applicability of Mixed Use Districts.  The MU District shall only be permitted on an area that merits special design considerations, involving a variety of property owners and uses within a developed urban environment.  The MU District shall be sufficiently cohesive and substantial to achieve objectives identified in any applicable adopted comprehensive plan.

c.    Parking lots – Parking lots shall not dominate the frontage of pedestrian-oriented and image streets or conflict with pedestrian crossings.  No parking space shall be closer to the primary frontage street than the building.

d.    Facades – Blank walls in excess of 50 feet shall be avoided.  Buildings with multiple storefronts should be unified in character and compatible with any upper floors.

e.    Transition yards and landscaping – Where a commercial lot abuts a residential use, a landscaped yard consisting of, but not limited to, trees, vegetation, wood fencing, landscaped earthen berm, or other plantings shall be provided for as a visual buffer that creates spatial separation.  Front yard setback areas shall be landscaped.  Landscaping plans shall be submitted to the Zoning Administrator for approval.

f.     Open storage – Any open storage visible from the street, adjacent to residential uses shall be screened to substantially reduce visual impact by fencing, landscaping, or other appropriate means.
