ORDINANCE NO. 195
AN ORDINANCE AMENDING CHAPTER 20 OF THE
CHANHASSEN CITY CODE, THE ZONING ORDINANCE,
CONCERNING LANDSCAPING STANDARDS
THE CITY COUNCIL OF THE CITY OF CHANHASSEN ORDAINS:
Section 1. 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.

(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. Section 20-1181 of the Chanhassen City Code is amended to read:
Sec. 20-1181. Vehicular areas.
. (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.

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.
Interior landscaping may be peninsular or island types. Landscaped area shall include
all parking lot and drive islands and perimeter green spaces. Required setback areas
shall be excluded.
(2) For each one hundred (100) square feet, or fraction thereof, of vehicular use area,
eight (8) square feet of landscaped area shall be provided.
(3) The minimum landscape area permitted shall be two hundred (200) square feet,
with six foot minimum dimension to all trees from edge of pavement where vehicles
overhang and a four foot minimum dimension to all trees where vehicles do not
overhang.
(4) In order to encourage the required landscape areas to be properly dispersed, no re-
quired landscape area shall be larger than seven hundred twenty (720) square feet in
vehicular use areas under thirty thousand (30,000) square feet, unless there is a tree
preservation area. In both cases, the least dimension of any required area shall be
four -foot minimum dimension to all trees from edge of pavement where vehicles
• overhang. Landscape areas larger than above are permitted as long as the additional
areas are in excess of the required minimum.
(5) A minimum of one (1) tree shall be required for each two hundred fifty (250)
square feet or fraction thereof, of required landscape area. Trees shall have a clear
trunk of at least five (5) feet above the ground, and the remaining area shall be
landscaped with shrubs, or ground cover (not to include rocks or gravel except as a
mulch around shrubs and ground cover), not to exceed two (2) feet in height.
(7) All landscaped areas shall be protected by concrete curbing.
(8) All landscaping area shall have the proper soil preparation to ensure the viability
of the vegetation to survive. The landscaping plan shall provide specifications for
proper soil preparation.
Section 3. Section 20-1182(c) of the Chanhassen City Code is amended to read:
(c) Boulevard and streetscape plantings. Where undeveloped or open areas of a site are
located adjacent to public right-of-way, the plan shall provide for over -story boulevard trees.
A minimum of one (1) tree for every thirty (30) feet of frontage is required. The city may

complete coverage otherwise is achieved. Grass sod shall be clean and free of weeds
and noxious pests or diseases. Ground cover such as organic material shall be planted
