For purposes of this chapter the following definitions shall apply unless the context clearly indicates or requires a different meaning.
DECIDUOUS SPECIES (TREES AND SHRUBS). Deciduous species are non-evergreen with broad leaves that shed all or most of its foliage annually.
(1) Low deciduous shrub, two to five feet in height; to be planted at least two and one-half to three feet apart.
(2) Medium deciduous shrub, five to eight feet in height; to be planted at least three to four feet apart.
(3) Tall deciduous shrub, eight to ten feet in height; to be planted at least four to six feet apart.
(4) Low deciduous tree, 15 to 30 feet in height; to be planted at least 15 to 30 feet apart, depending on spread.
(5) Medium deciduous tree, 30 to 40 feet in height; to be planted at least 20 to 35 feet apart, depending on spread.
(6) Tall deciduous tree, 40 to 100 feet in height; to be planted at least 40 to 50 feet apart; columnar species, 20 to 30 feet apart.
EVERGREEN SPECIES (TREES AND SHRUBS). Evergreen species remain green and mostly retain their foliage throughout the year. Evergreens can be categorized as narrow-leaf coniferous species or as broad-leaved species.
(1) Low evergreen shrub, six to 24 inches in height; to be planted at least two and one-half to three feet apart, depending on spread.
(2) Medium evergreen shrub, two to eight feet in height; to be planted at least four to six feet apart, depending on spread.
(3) Tall evergreen shrub, eight to ten feet in height, sometimes 15 feet; to be planted at least six to eight feet apart, depending on spread.
(4) Low evergreen tree, 15 to 40 feet in height; to be planted at least 10 to 25 feet apart, depending on spread.
(5) Medium evergreen tree, 40 to 60 feet in height; to be planted at least 25 to 35 feet apart, depending on spread.
(6) Tall evergreen tree, 60 to 80 feet in height; to be planted at least 25 to 35 feet apart, depending on spread.
HARDSCAPE. Whereas landscape elements are living and organic, hardscape elements are inanimate site features of the built environment. HARDSCAPE typically refers to a site's walkways, drives, seat walls, ramps, steps, plazas, courtyards, pools, fountains and similar outdoor features and use areas. They are comprised of hard wearing materials such as stone, brick, and concrete as opposed to soft landscape materials such as grass, bark and plantings areas.
IMPERMEABLE SURFACE. Surfaces that are composed mainly of artificial structures such as roadway pavements, walks, driveways and parking lots, and are covered by mostly impenetrable materials such as asphalt, concrete, brick, stone, and rooftops. An impermeable surface is composed of materials that water will not readily penetrate thereby sealing the soil surface and eliminating rainwater infiltration and natural groundwater recharge.
PERMEABLE SURFACE. A permeable surface in the context of this chapter is one, such as soil, that will allow sufficient water to penetrate the surface, and that will allow absorption of water and provide nutrients to enable the growth of tall shade trees.
TOPOGRAPHY. The topography of a site is its three-dimensional shape and involves the recording of surface terrain and the identification of specific landforms.
VIEWSHED. A viewshed is the geographical area (of land and water) that is visible from a fixed vantage point. It includes all surrounding points that are in line-of-sight with that location and excludes points that are beyond the horizon or obstructed by terrain and other features (such as buildings and trees). The term is used in urban and rural planning to identify areas of particular scenic and/or historic value that are deemed worthy of preservation. The preservation of viewsheds is frequently a goal in the designation of open space areas, green belts, and community separators,
