The requirements of this article are intended to help achieve several functional and environmental objectives such as:

A.

To improve the local environment by controlling soil erosion, moderating harsh or unpleasant sounds, removing air pollutants, controlling light trespass and reflection, moderating winds, and the effects of climate, and promoting stormwater infiltration thereby helping to prevent flooding.

B.

To encourage the preservation of existing trees and vegetation;

C.

To provide visual buffering and enhance the beautification of the Village;

D.

To reduce the physical impact between adjacent land uses by requiring complementary landscape treatments and providing a transitional area adjacent to natural areas;

Such street trees shall be located within the street right-of-way, said trees shall meet the minimum size requirements set forth in subsection 14.06.B of this section and shall be an appropriate species for a street environment. The Planning Commission, Zoning Enforcement Officer, Village Manager (or designee) may determine that existing trees which are preserved within the road right-of-way or easement may meet all or a portion of the street tree requirement.

C.

Buffer Zones between land uses.

1.

A landscape buffer shall be required to create a visual screen at least six (6) feet in height along all adjoining boundaries whenever a non-residential use or a residential use of higher density abuts residentially zoned property. A landscape buffer may consist of earthen berms and plant materials, or plant materials only, so as to maintain a minimum opacity of at least eighty (80%) percent. Opacity shall be measured by observation of any two (2) square yard area of landscape screen between one (1) foot above the established grade of the area to be concealed and the top or the highest point of the required screen. Provided the minimum size of plant material as set forth in subsection 14.06.B of this Section at the time of installation, the opacity standard shall be met based upon reasonably anticipated growth over a period of three (3) years. At the time of the initial planting, the applicant shall agree in writing to install additional plantings after the expiration of three (3) years in the event that the landscaping has not screened the view of areas as required.

2.

Where there is a need to provide a greater visual, noise or dust barrier or to screen more intense development, a solid wall, fence or berm or combination thereof may be required by the Planning Commission, Zoning Enforcement Officer or Village Manager (or designee). Such wall or fence shall be a minimum of six (6) feet in height, or up to an eight (8) foot berm and/or wall within the commercial and industrial districts, as measured on the side of the proposed wall having the higher grade and shall be constructed on both sides with textured concrete, split-face concrete block, wood, brick, or stone. Precast panels and formed concrete structures may be used if they provide surface detail and texture equal to or greater than, the materials just named. The location may be modified by the Planning Commission, Zoning Enforcement Officer or Village Manager (or designee) upon recommendation of the Village Engineer due to unique circumstances, such as conflicts with underground utilities and better screening provided at alternative locations. In addition, a minimum of one (1) tree and six (6) shrubs meeting the minimum size requirements set forth in subsection 14.06.B of this section shall be planted adjacent to and for each thirty (30) lineal feet of wall or fence.

3.

Any zoning district or use adjacent to the US-23 right of way shall be required a buffer width of no less than fifty (50) feet alone the property line. This buffer area shall include one (1) canopy tree per each thirty (30) linear feet, and two (2) evergreen trees per each twenty (20) liner feet. Furthermore, a berm and/or masonry wall may be required in place of the buffer when deemed necessary by Planning Commission, Zoning Enforcement Officer or Village Manager (or designee) to meet the intent of Section 14.05.C.

D.

Parking lot landscaping.

1.

Interior areas. Each separate landscaped area within a parking lot shall be adequately planted and maintained and shall be located in such a manner as to promote the following: divide and break up the expanse of pavement; define parking areas; designate vehicular circulation; and separate parking lots from off-street parking. The following specific standards shall apply:

a.

Parking Islands. Separate landscaped islands shall be required within parking lots of sixteen (16) spaces or greater. No more than a row of twenty-four (24) spaces, that range from a thirty (30) degree to a ninety (90) degree angle from a curb, the edge of parking surface, or vehicular access aisle are permitted without an island. In parking lots containing parking spaces parallel to a curb, the edge of parking surface, or vehicular access aisle, no more than a row or nine (9) spaces shall be permitted without an island. Where size and configuration of a parking lot would prevent maintenance or impede traffic flow as a result of requiring landscaped areas within parking lots, the Planning Commission, Zoning Enforcement Officer or Village Manager (or designee) may approve alternative landscaping along the perimeter of the parking lots.

b.

There shall be one (1) canopy tree meeting the minimum size requirements set forth in subsection 14.06.B of this section for every eight (8) parking spaces, landscaped islands within a designated parking area shall be a minimum of one hundred-fifty (150) square feet in area and nine (9) feet in width; no branches shall remain within four (4)—six (6) feet above the grade of the parking lot.

c.

A minimum distance of three (3) feet shall be established between proposed tree or shrub plantings and the backside of the curb or edge of the pavement.

2.

Perimeter areas. To reduce the visual impact, minimize conflicts between neighboring uses and reduce the effect of headlight glare and parking lot lighting on adjacent uses and public roadways, the perimeter of parking lots shall be screened in accordance with the following standards (see figure below):

a.

Parking lots which are adjacent to residentially zoned or used property, which serve a non-residential use, or a residential use of higher density shall be screened from that residential use in accordance with the standards set forth in Section 14.05.C.

b.

Parking lots adjacent to like zoning districts shall provide a perimeter buffer area of no less than ten (10) feet wide from the edge of pavement and screened with a minimum of one (1) deciduous per each two thousand (2,000) square feet of paved surface, meeting the minimum size requirements set forth in subsection 14.06.B of this section.

c.

Parking lots which are visible from a public road shall follow the requirements of Section 14.05.E - Front Greenbelt Landscaping.

d.

The Planning Commission, Zoning Enforcement Officer or Village Manager (or designee), at its discretion, may approve alternative landscape plantings, such as a solid hedge, or a solid wall in lieu of a landscape berm. Decorative treatment may be incorporated into the perimeter parking lot landscaping such as the inclusion of tree clusters, or a two and half (2.5) foot tall wood fence, brick wall or wrought iron fencing with brick pilasters. Treatment provided must be compatible with, or a site improvement to, surrounding properties. This decorative treatment is encouraged on sites within the business districts and multiple-family developments near the downtown.

3.

Landscape strips. Minimum of four (4) foot wide landscape strips (not including vehicle overhangs) should be provided between paved parking surfaces and buildings, fences, and property lines wherever possible. Trees and shrubs shall be planted clear of the vehicle overhang area. For locations abutting an exterior building wall where sidewalks are required; landscape stripe shall be placed between the sidewalk and building wall.

E.

Front greenbelt landscaping.

1.

A minimum of a twenty (20) foot wide greenbelt shall be required for any lot or any portion of an interior or corner lot fronting on a public or private road, and shall be landscaped with a minimum of one (1) deciduous tree or one (1) evergreen tree, plus six (6) deciduous and/or evergreen shrubs meeting the minimum size requirements set forth in subsection 14.06.B of this section for each forty (40) lineal feet, or major portion thereof, of frontage abutting said public right-of-way. The remainder of the greenbelt shall be landscaped in grass, ground cover, shrubs and/or other living plant material. (See figure below).

2.

Access-ways from public rights-of-way through required landscape strips shall be permitted, but such access-ways shall not be subtracted from the lineal dimension used to determine the minimum number of trees required unless such calculation would result in a spacing arrangement which is detrimental to plant development.

3.

Greenbelt plantings shall be arranged to emulate the landscape character of the surrounding areas. Subject to Planning Commission determination, the greenbelt plantings may be waived within the B-1, Central Business District providing the buildings are located at or near the property line.

F.

Subdivision and site condominium landscaping. Landscaping for subdivisions and site condominiums, which shall include, but not be limited to, residential, office, commercial, and industrial development, shall be provided in accordance with the following requirements:

1.

Such street trees shall meet the minimum size requirements set forth in subsection 14.06.B of this Section and shall be an appropriate species for a street environment. The Planning Commission may determine that existing trees which are preserved within the road right-of-way or easement may meet all or part of the street tree requirement.

2.

Screening from public roads. Where a subdivision or site condominium abuts a public right-of-way located outside of the proposed subdivision or site condominium, the screening requirements set forth in subsection (1) of this section shall be met.

3.

Other site improvements. A landscape plan for a subdivision or site condominium development shall also include landscaping details of the entrance to the development, cul-de-sac islands, stormwater retention and/or detention areas, community buildings and other recreational areas, and any other site improvement which would be enhanced through the addition of landscaping.

G.

Foundation landscaping. Foundation plantings shall be provided along the front or sides of any buildings which faces a public road and/or is adjacent to a parking lot or other area which provides access to the building by the general public. Foundation planting areas shall be integrated into the sidewalk system (between the front and sides of the building and the parking area and/or associated driveways) adjacent to the building. Foundation planting areas shall contain, at a minimum, one (1) ornamental tree and (6) six shrubs per thirty (30) lineal feet of applicable building frontage. Individual planting areas shall be a minimum of eight (8) feet in width.

H.

Retention and detention areas. The integration of stormwater retention and detention areas in the overall landscape concept is recommended. Retention and detention areas with a natural/free form design and appearance shall be encouraged. Fenced retention/detention areas within a front yard shall be strictly prohibited. Each retention or detention area shall have one (1) tree per each fifty (50) linear feet measured at the top bank of the pond and ten (10) shrubs per each fifty (50) linear feet measured at the top bank of the pond plus a native seed mix on the slopes to prevent erosion. The plantings shall be clustered in a natural pattern around the basin with trees above the freeboard line, and all other plantings must be tolerant of wet/moist soils. The location of plant material shall also be done in consideration of the need to provide access for and minimize disruption of plant material during routine pond maintenance.
