Landscaped areas along street frontages shall be contoured or bermed to provide variations
in grade, visual relief, parking lot screening, and a more pleasing aesthetic value.
All on-site parking areas shall be screened from street view by a landscaped berm
or decorative wall not less than four (4) feet in height. The required height of the
berm or wall shall be measured from the highest finished grade of the adjacent on-site
parking area or adjacent finished grade of the street, whichever is greater.
