Section 20-1180 of the Chanhassen City Code is amended to read: Sec. 20-1180. Screening for visual impacts. (a) Undesirable visual impacts must be screened. Undesirable visual impacts include, but are not limited to, truck loading areas, trash storage, parking lots, interior lot areas and perimeters, outdoor storage areas, large unadorned building massing, garage doors associated with auto -oriented uses and vehicular stacking areas for drive -through uses. (1) Required screening for any visual impact may be achieved with fences, walls, earth berms, hedges or other landscape materials. All walls and fences shall be • architecturally harmonious with the principal building. The use of wooden screen fences or chain link fences equipped with slats is prohibited. Earth berms shall not exceed a slope of 3:1 unless provided with landscaping designed to minimize mainte- nance. The screen shall be designed to provide effective visual barrier during all seasons. (2) All required screening shall be located on the lot occupied by the use, building, facility or structure to be screened. No landscape screening shall be located on any public right-of-way or within eight (8) feet of the traveled portion of any street or highway. (3) Screening required by this section shall be of a height needed to accomplish the goals of this section. Height of plantings required under this section shall be measured at the time of installation. (4) Parking lot screening shall limit direct views of pavement and direct views of vehicles parked near the exterior of the site. It is not intended that this requirement result in significantly obscuring views of principal structures or permitted signage. (5) The City may make special allowances for establishing screening requirements for long term parking areas such as those developed for transit related park -and -ride facilities. Due to their characteristics of long duration parking coupled with long hours 10 having little or no activity, these lots may present special problems related to safety that require enhanced visibility. 1467 111/03/93 (b) The following uses shall be screened in accordance with the requirements of this subdivision: (1) Principal buildings and structures and any building or structure accessory thereto located in any business, industrial or planned unit development district containing nonresidential uses shall be screened from lots used for any residential purpose. (2) Principal buildings and structures and any building or structure accessory thereto located in any R4, R8, R12, R16 district or planned unit development district con- taining residential development at densities exceeding four (4) units per acre shall be screened from lots located in any Al, A2, RR or RSF district. (3) Additional buffer yard requirements are established by the city comprehensive plan and listed in individual district standards. (4) Outside storage in any district subject to these provisions and allowed by other provisions of this ordinance, shall be screened from all public views. Section 2.

(a) When parking lot perimeters of vehicular areas, including driveways and drive aisles, are not entirely screened visually by an intervening building or structure or land mass from any abutting right-of-way, there shall be provided landscaping designed to buffer direct views of cars and hard surface areas. The landscaping must break up expanses of hard surface areas, help to visually define boulevards and soften direct views of parking areas and provide for reforestation with overstory tree from the approved tree species list identified for parking or other species as approved by city staff. All new planting areas must have an irrigation system installed. Publicly owned and operated parking lots used for long duration parking may be exempt from this requirement when there is a demonstrated concern regarding security safety. • N 9467 2 r11/03/93 49 (b) Interior landscaping for vehicular use areas: (1) Any open vehicular use areas containing more than six thousand (6,000) square feet of area, or twenty (20) or more vehicular parking spaces, shall provide interior landscaping in accordance with this division in addition to "perimeter" landscaping.
