Landscaping required for one purpose is in addition to landscaping required for other purposes (i.e., streetscape landscaping is in addition to landscaping required for visual screening of parking, open space, parking lot, etc.).
A. Streetscaping: Along South 60th Street, streetscape landscaping shall be provided within the first twenty five feet (25') parallel to the roadway as measured from the ultimate street right of way line.
This streetscape landscaping is intended to provide for the enhancement of the travelways. Buildings may intermittently encroach into the landscaped area; however parking lots or accessory structures may not. The plantings shall be installed with the development of the property. Landscaping standards are as follows:
1. To calculate the number of required plants, divide the total linear feet of street frontage by thirty (30). For every thirty feet (30'), one tree and two (2) shrubs shall be required. The landscaping may be arranged in massing or in a linear streetscape or a combination thereof.
2. No substitutions for trees may be allowed.
3. Alternative concepts that meet the intent of streetscape landscaping may be allowed at the discretion of the development planning and inspection manager.
B. Parking Lot/Vehicle Use Area Landscaping: The intent of this section is to encourage extensive landscaping within parking lot areas, which tend to have the greatest negative impact on developments, and to provide breaks in what could be viewed as a "sea of parking". Whenever possible, a series of smaller parking lots/areas separated by visible green areas shall be implemented in lieu of one large parking expanse. Each area shall be landscaped and screened from views from the public streets and adjacent properties which are not part of the Denton development. Parking lots shall be designed to function not only in the interest of accommodating automobiles, but also in the interest of promoting safe pedestrian movement. The following parking lot landscaping standards are in addition to the required buffer park, streetscape or plaza landscaping requirements:
1. Landscape islands shall be located at the terminus end of parking rows. In addition, landscape islands shall be placed, at a minimum, every eighteen (18) stalls within a row of parking. Landscaped islands shall be, at a minimum, ten feet (10') wide and thirty six feet (36') in length for dual parking rows or a minimum of ten feet (10') wide and eighteen feet (18') in width for single rows.
2. Landscaped pods (tree diamonds) within a row of parking shall be evenly spaced between landscape islands, however, shall be spaced no farther than nine (9) parking stalls from another landscaped pod or landscaped island. Landscaped pods shall measure no less than six feet (6') to back of curb in each direction.
3. A minimum of one overstory tree shall be located in each nine foot by eighteen foot (9' x 18') island area and every tree pod (tree diamond). In addition, for every twelve (12) parking stalls, two (2) shrubs or a twenty (20) square foot massing of perennials or ornamental grasses shall be located within the islands or pods within the parking area. If ornamental grasses are implemented, it is encouraged to implement a variety that is a minimum of three feet (3') in height so that the grasses are visible amongst the vehicles.
4. Parking lots, drive lanes and loading areas visible from the public street and adjacent properties outside of the Denton development shall provide appropriate screening through the use of any of the following:
a. Earthen berms which are generally three feet (3') or higher in conjunction with implementation of vegetation, except where visibility at intersections may be impacted.
b. Landscape walls:
(1) Freestanding walls implemented for screening measures shall be treated to a finished state on both sides of the wall.
(2) Walls constructed for the retainment of soil which are greater than four feet (4') in height must be designed by an individual knowledgeable and certified in structural engineering. Walls over four feet (4') shall have one and one-half feet (11/2') of horizontal terraces for every two feet (2') of exposed vertical wall face. Exceptions to this requirement may be granted by the development planning and inspection manager for unusual situations and to preserve existing vegetation or landscape features.
(3) Walls may be brick, individual decorative modular wall stone, or natural stacked wall or field stone. Walls composed of landscape timbers or other wood products are not desired due to the deterioration potential of the material. With approval by the development planning and inspection manager, wood walls or other material may be used in areas where views of the wall will be minimal.
(4) Vegetation shall be planted along all types of walls to soften the visual impact, visually break up long expanses of the wall and to visually anchor it to the site.
c. Screening through the implementation of predominately evergreen materials which reach a minimum of three feet (3') in height. Vegetation implemented for screening purposes shall be implemented at a size that is larger than normal in order to accomplish immediate screening. (Ord. 2035, 5-19-2014)
