Sec. 38-03 Definitions.
Buffer. A combination of physical space and vertical elements such as plants, fences or walls, the purpose of which is to separate and screen incompatible land uses from one another.
Canopy. The shaded cover created by spreading branches of a large deciduous tree.
Commercial grade shredded hardwood mulch. A dark brown, finely shredded wood product supplied to landscapers and garden centers for the purpose of mulching landscaped beds. This would not include the shredded, fresh wood from tree trimming or removal that is commonly available from municipalities and park districts.
Commercial strip. A strip of landscaping along the main
thoroughfare, in front of a building.
Common name. The moniker by which a plant is most likely to be known locally, such as “honey locust.”
Deciduous. A woody plant that sheds its leaves annually.
Evergreen. A woody plant with foliage that persists and remains for more than two consecutive seasons.
Foundation shrubbery. Woody plants, evergreen or deciduous, used to soften and hide the foundation of a building or wall.
Groundcover. Plants other than turf grass used to cover large areas of planting beds. May be woody or herbaceous, evergreen or deciduous, but generally spreading in nature and not exceeding twenty-four inches in height.
Habitat. The natural elements of an ecosystem including food, shelter and nesting material from plants.
Herbaceous. Of plants with soft (not woody) top growth that generally dies back in winter (i.e...herbaceous perennials such as Hosta). Some herbaceous plants are evergreen or semi-evergreen in winter, retaining leaves until new growth appears in spring, such as Liriope.
Hose bib. A spigot or connection for a watering apparatus on a building or otherwise located on the property.
Landscaped area. An area that is covered by living plant material.
Latin name. A scientific name composed of the genus, species and cultivar or variety (where applicable) of a plant.
Maintenance area. Areas on the out lot or around the building that are used for trash, equipment or storage, excluding sheds and buildings.
Male clone. For the purposes of this ordinance, a woody plant that is propagated asexually, rather than sexually, thereby insuring male plants that do not bear fruit.
Mulch. Non-living organic material used in landscapes to retard moisture loss, control weeds and erosion and keep soil temperatures consistent for plant roots.
Nuisance weed trees. Fast growing trees that become invasive through seed dispersal, suckering and underground runners. Such trees that become an economic and physical liability to nearby property owners thus the term “nuisance.”
Perimeter strip. A continuous landscaped strip along all public right of ways, not including alleys.
Shade tree. A deciduous woody plant, usually with a single stem, that exceeds fifteen feet in height and provides shade when in leaf.
Shrub. A woody plant, deciduous or evergreen, characterized by multiple stems and branching from the base, usually not more than twelve feet in height at maturity.
Understory. Assemblages of naturally lower growing, woody and evergreen species which grow or exist below the canopy of trees.
Turf grass. Cool season grasses such as fescue, rye and bluegrass, seeded or sodded, to create a lawn that is mowed and kept free of invasive plants.
Vines. For the purpose of the ordinance, vines shall be defined as woody plants that cling to surfaces by means of aerial rootlets, twining or other tropic mechanisms of stem or petiole.
Sec. 38-04 Requirements.
A. Buffer Strips. Landscaped buffer strips shall be used in all instances of incompatible use. Incompatible use will be considered to exist when any new commercial, industrial, public or institutional development is sited along shared property lines or alleyways with existing residential properties, schools, places of worship, daycare facilities and parks, even in the event that these properties lie outside the corporate boundaries.
1. Landscaped buffer strips shall consist of at least one of following three options:
(a) A ten foot wide, heavily planted strip consisting of three planting layers: canopy, understory and groundcover. The strip shall be continuous along the shared property line or right of way and include shade trees at twenty-five foot intervals, an understory of deciduous or evergreen shrubs planted in clusters of three or more and spaced at four foot intervals and a groundcover planting of herbaceous plant material over remaining bed surface; or,
(b) A five foot wide bed along a solid surface wall, six foot minimum height, running continuously along the shared property line or right of way. Said wall must be planted with foundation shrubbery and vines to cover. Walls may be constructed of wood or masonry and may not be constructed of plastics or composites; or,
(c) A fifty foot wide planting of turf grass or groundcovering plant material running continuously along the shared property line or right of way, with shade trees planted at twenty-five foot intervals.
B. Perimeter Strips. Landscaped perimeter or commercial strips shall be planted in all parking areas in excess of five hundred square feet, as follows:
1. Perimeter landscaped parking strips shall be used continuously (excepting cut-ins) along all public right of ways, not including alleys, unless a continuous landscaped commercial strip at least ten feet deep, planted with canopy, understory and groundcovering plants is substituted along the main thoroughfare In any case, a minimum of fifteen percent of the parking area shall consist of landscaped parking strips.
2. Internal islands of landscaped parking strip shall be used at a minimum of seven and one-half percent of the vehicular use area, not including perimeter strips, of any parking lot in excess of thirty-thousand square feet. The landscaped area shall be designed, dispersed and located within and around the vehicular use areas to enhance the appearance and safety of the vehicular use area.
3. Perimeter landscape strips must be a minimum of five feet wide and consist of shade trees planted at twenty-five foot intervals, an understory planting of deciduous or evergreen shrubs or shade trees planted at twenty-five foot intervals and a ground-covering plant layer of turf grass or other herbaceous ground-covering plant material.
4. Internal landscaped islands shall be a minimum of one parking space in width and length and consist of a minimum of one shade tree and an under-story planting of deciduous or evergreen shrubs or a minimum of one shade tree and a ground-covering plant layer of turf grass or other herbaceous ground-covering plant material.
5. A commercial strip, when used instead of continuous perimeter strips shall be at least ten feet deep and run continuously along the main thoroughfare (excepting cut-ins) and consist of shade trees planted at twenty-five foot intervals, deciduous or evergreen shrubbery in clusters of three or more, planted no less than ten feet apart and turf grass or ground-covering plants in the remaining bed surface.
6. Landscaped strips consisting only of trees and shrubs, and not herbaceous ground-covers or turf, shall be mulched at a depth of six inches with commercial grade shredded hardwood mulch.
7. When tree spacing at twenty-five foot intervals is called for, it is assumed that a twenty-five foot bed will require two trees and that two smaller beds, separated by cut-ins, will be measured contiguously.
C. Materials. All landscape plant material used in the above outlined areas must be purchased and sized in accordance with The American Standard for Nursery Stock (most recent addition).
1. In addition, plant material to be installed must be selected for appropriateness to climate, soil types and suitability to use area. (See tables in Article II, Plant Selection)
2. Plant material to be installed must be healthy, free of insects, disease and significant physical damage.
3. A landscape plan shall be required, from either the developer or landscaper, as part of the development process and include the following:
(a) A scale drawing.
(b) Proposed structures and pavement.
(c) Proposed landscaped areas, showing location of all plant material and a list of plant material, using Latin and common names, quantities and sizes.
(d) Location of hose bibs and irrigation systems.
D. Maintenance.
1. Landscape care shall be the responsibility of the owner, tenant or their agent and include the following:
(a) Landscaping shall be maintained in good condition so as to present a neat, healthy and orderly appearance and shall be kept free of weeds and dead plant material.
(b) Any diseased, dead or dying plant must be removed and replaced with a plant of comparable size and quality, when possible.
(c) Watering must be done in a manner that allows plants to become established and prevents plants from dying; except during times that watering may be prohibited by local order.
(d) The City shall have the right to prune any tree or shrub on private property when it interferes with visibility of any traffic control device or sign: or when it creates a hazard to life or property.
(e) The City shall have the right to cause the removal of any tree or shrub on private property that harbors insects or diseases that pose a potential threat to the tree population of the City as determined by the City arborist.
2. Maintenance areas used for storage and trash must be enclosed by a solid wall of no less than six feet in height and covered by a planting of woody vines. Vines shall be used at a minimum spacing of one vine for every ten feet of surface width. Walls may be constructed of wood or masonry and may not be constructed of plastics or composites. Walls that are seated on concrete or asphalt, and provide no possibility for planting must be constructed of masonry.
3. A minimum of one hose bib for every ten-thousand square feet of developed lot shall be provided and a hose bib must be located no more than one-hundred feet from any landscaped area.
4. Nuisance weed trees, as outlined in
Article II (see table of unacceptable trees) of this ordinance, shall be
removed when such trees exceed a height of ten inches, pursuant to the BOCA
International Property Maintenance Code, Section 302.4. This specific provision
of this ordinance shall also apply to all commercial, public, industrial,
institutional and private developments (excepting single and multiple family
dwellings) existing within the City of
