All plant materials and living ground cover must be selected and maintained so that the entire landscaped area will be covered a minimum of seventy-five percent within five years, with maximum coverage in eight years.

Any combination of trees (deciduous or evergreen), shrubs, earthen berms and related plant materials or design are allowed, provided that the resultant effect is sight-obscuring from adjoining properties.

All trees and shrubs must be capable of growing to a minimum six feet and three and one-half feet in height respectively.

Deciduous trees and a combination of shrubs and/or ground cover approved by the town and as set forth herein:

Shrubs shall be a minimum of one and one-half feet in height at the time of planting and may be dispersed throughout the landscaped planting area or in confined pockets or nodes.

Ground cover shall be designed to cover sixty percent of the required area. Ground cover shall consist of grass, shrubs, vines, or other similar living ground cover. The remaining area may be covered with bark, rock or other similar material. These areas may also contain trees, shrubs, and other permitted plant materials and pedestrian amenities (i.e., benches), however, areas planted in grass shall be designed and constructed in a manner that will make possible normal maintenance such as mowing and watering. Ground cover shall be planted so that a minimum of seventy-five percent of the area is covered at maturity within five years.

Street trees shall be planted adjacent to the right-of-way, but not closer than three feet to a public sidewalk or curb. In no case shall sight-obscuring landscaping be located within the clear view triangle area as set forth in Chapter 17.44

It shall be the responsibility of the owner(s) of the lot adjacent to the streetscape area to maintain the trees and planting area in good growing condition and to replace dead or dying trees with similar tree or shrub species. The town shall have the right to prune and maintain trees and shrubs within the lines of the right-of-way, clear view triangle and other public areas as may be necessary to ensure public safety.

A combination of deciduous and/or evergreen trees, shrubs, and ground cover:

Shrubs shall be a minimum of one and one-half feet in height at the time of planting with approved living ground cover. Plant materials shall be planted so that the ground will be covered a minimum of seventy-five percent within five years.

Earthen berms with grass, vegetative ground cover or other landscaping features should be designed with the required landscaping standards of this chapter, provided the resultant effect would provide a pedestrian friendly environment and visual relief where clear sight is required and can be achieved.

A combination of evergreen or deciduous trees or shrubs and ground cover planted adjacent to buildings in the following areas shall meet the criteria as prescribed herein:

A minimum of thirty percent of the area as measured along the length of a building or structure shall be planted and landscaped in areas identified in subsection (D)(1)(a) of this section.

The landscape area shall not be located greater than fifteen feet from the building or structure.

Accessory buildings associated with the primary use shall be exempt from the above requirements.

Landscaping located at road intersections or within a clear view triangle shall not exceed three and one-half feet in height as measured from road grade and shall meet the minimum criteria established in Chapter 17.44 for clear view triangle.

Required Amount.

Each area of landscaping must contain at least one hundred square feet of area and dimension and shall not be less than six feet in any direction. The area must contain at least one tree six feet in height at the time of planting. The remaining ground area must be landscaped with plant materials.

A landscaped area must be placed at the interior end of each parking row in a multiple-lane parking area. Each area must be at least four feet wide and must extend the length of the adjacent parking stall(s).

One shade tree shall be planted within the interior of the off-street parking area for every ten parking stalls. The first priority in meeting this provision is to preserve existing, well-established trees that do not interfere with the safety, operation and functioning of the parking lot. The trees shall be capable of providing shade to an area equal to thirty percent of the parking facility within fifteen years of planting.

All landscaped islands must have a minimum depth of topsoil of two feet for shrubs and four feet for trees, unless poor drainage conditions exist which would require modifications as approved by the town.

All landscaped islands shall be planted with a combination of shade trees, shrubs or living ground cover. This area may contain ornamental trees and shrubs if appropriate. All planting must be in the central portion of the island.

Screen planting of a dense evergreen material not less than five feet in height at the time of maturity shall be provided in any locations where lights from vehicles within the off-street parking area may shine directly into windows of adjacent residential buildings. In lieu of screen planting, up to fifty percent of the required landscaping may be subtracted when a solid rock, masonry or wood fence is constructed, provided the fence is at least forty-two inches high, but does not exceed five feet in height.

A screen planting of dense evergreen material not less than five feet high at the time of planting shall be required where overhead illumination is located within the off-street parking area and may shine directly into windows of adjacent residential buildings. The town may require a greater height if it is determined that the screen planting of five feet high does not properly screen the overhead illumination from adjacent residential buildings. Parking lot lights will not be permitted to shine over property boundaries.

Provisions shall be made to ensure that adequate pedestrian paths connecting the parking lot with the public right-of-way are provided throughout the landscaped areas.

All areas in a parking facility not used for driveways, maneuvering areas, parking spaces or walks shall be permanently landscaped with suitable materials and shall be permanently maintained, pursuant to a maintenance program submitted by the applicant and approved by the community development director.

All landscaped areas shall have a border, as approved by the community development director, such as railroad ties or blocks, to retain the landscaping materials and also to protect them from intrusion by vehicles. All landscaped areas shall be a minimum of six feet in width and contain a minimum area of sixty square feet. Except within fifteen feet of a driveway, landscaped areas may include berms, ornamental block walls and similar techniques that provide variations and/or modulations in elevation, texture and similar characteristics.

To increase the parking lot landscaped area, a maximum of two feet of the parking stall depth may be landscaped in lieu of asphalt while maintaining the required parking dimensions.

All parking facilities shall be permanently maintained in such a way that dust is not emitted from the parking lot, and shall be free of weeds, litter, debris and graffiti. Parking lots shall be striped biannually.

Where lighting is provided, it shall be of low intensity and the lighting shall be shielded in such a way that light and glare is directed only onto the subject property.

The minimum landscaping width along the rear and side yards may be reduced to an amount approved by the director, but in no case shall it be less than five feet, if an ornamental wall or fence is constructed in conjunction with the landscaping required.

The director may increase the minimum width of a landscaped area and type of planting if the use is located adjacent to a lower intensity use.

If existing, well-established trees that have a trunk diameter of six inches or greater, as measured four feet above ground level, and/or vegetation (excluding noxious weeds and grasses) can realistically be utilized, they should be preserved and incorporated into the overall landscape program.

When the inclusion of significant existing vegetation located on the site would result in as good as or better satisfaction of the purposes of this section;

When the landscaping would interfere with the adequate flow of stormwater runoff, as determined by the town engineer along drainage easements and/or when the landscaping would interfere with the adequate treatment of stormwater in grassed percolation areas;
