9.6210 Description of Landscape Standards

(a) Required Plant Materials. Basic Landscape Standard (L-1) requires the installation and maintenance of all of the following:

1. 1 tree per 30 linear feet as measured along the front lot line.

2. 6 shrubs per 30 linear feet as measured along the front lot line.

3. Living plant materials covering a minimum of 70 percent of the required landscape area within 5 years of planting.

The required plant materials may be installed in the required area in any arrangement and do not need to be linear in design.

(b) Exceptions to Required Plant Materials. An exception to the requirement in subsection (a)1. above shall be granted if any of the following conditions exist:

1. Excluding any required parking area landscaping, the landscape area required to comply with the L-1 Basic Landscape Standard is located entirely within 15 feet of a building.

2. The landscape area required to comply with the L-1 Basic Landscape Standard is located on the roof of a building or exposed terrace.

3. The landscape area required to comply with the L-1 Basic Landscape Standard is on a development site that has achieved a Floor Area Ratio (FAR) of at least 1.0.

(c) Criteria for Adjustment. This standard may be adjusted if consistent with the criteria of EC 9.8030(3)(b).

(a) Required Plant Materials. Low Screen Landscape Standard (L-2) requires the installation and maintenance of all of the following:

1. Low shrubs to form a continuous screen at least 30 inches high within 3 years and maintained at a height not to exceed 42 inches.

2. 1 canopy tree per 30 linear feet as measured along the lot line.

3. Living plant materials covering a minimum of 70 percent of the required landscape area within 3 years of planting.

A masonry wall or a berm between 30 and 42 inches high shall be permitted as a substitute for the required low shrubs, but the trees and other plant materials are still required. When applied along street lot lines, the masonry wall is to be placed farthest from the street with the required landscaping in between the wall and street. When applied along an abutting property the masonry wall may be placed along the interior lot line. (See Figure 9.6210(2) Low Screen Landscape L-2.)

(b) Criteria for Adjustment. This standard may be adjusted if consistent with the criteria of EC 9.8030(3)(c).

(a) Required Plant Materials. High Screen Landscape Standard (L-3) requires the installation and maintenance of all of the following:

1. High shrubs that are in at least 5 gallon containers at the time of planting to form a continuous screen, at least 6 feet high, within 5 years of planting.

2. 1 canopy tree per 30 linear feet as measured along interior lot lines.

3. Living plant materials covering a minimum of 70 percent of the required landscape area within 5 years of planting.

A masonry wall at least 6 feet high shall be permitted as a substitute for the shrubs but the trees and other plant materials are still required. When this landscape standard is applied along street lot lines, the screen or wall is to be placed farthest from the street with the required landscaping in between the wall and street. When applied along an abutting property the masonry wall may be placed along the interior lot line. (See Figure 9.6210(3) High Screen Landscape L-3.)

(b) Criteria for Adjustment. This standard may be adjusted if consistent with the criteria of EC 9.8030(3)(d).

(a) Required Materials. High Wall Landscape Standard (L-4) requires the installation and maintenance of all of the following:

1. Masonry wall at least 6 feet high with a maximum height of 8 feet. When applied along street lot lines, the wall shall be placed farthest from the street with the required landscaping in between the wall and the street. When abutting an adjacent parcel, the wall may be placed along the interior lot line.

2. 1 canopy tree is required per 30 linear feet of wall.

3. 4 high shrubs or vines are required per 30 linear feet of wall, and

4. Living plant material must cover a minimum of 70 percent of the required landscape area within 5 years of planting. (See Figure 9.6210(4) High Wall Landscape (L-4).)

(b) Criteria for Adjustment. This standard may be adjusted if consistent with the criteria of EC 9.8030(3)(e).

(a) Required Materials. Partial Screen Fence Landscape Standard (L-5) requires the installation and maintenance of fences at least 6 feet high with a maximum height of 8 feet that are at least 50 percent site-obscuring, such as a cyclone fence with slats. Vines are permitted on fences to fulfill the requirement for a screening fence provided they will be 50 percent site-obscuring within 5 years of planting. Fences may be made of wood, metal, masonry, or other permanent materials. (See Figure 9.6210(5) Partial Screen Fence Landscape (L-5).)

(b) Criteria for Adjustment. This standard may be adjusted if consistent with the criteria of EC 9.8030(3)(f).

(a) Required Materials. Full Screen Fence Landscape Standard (L-6) requires the installation and maintenance of fences at least 6 feet high with a maximum height of 8 feet that are 100 percent site-obscuring. Fences may be made of wood, metal, masonry or other permanent materials. (See Figure 9.6210(6) Full Screen Fence Landscape (L-6).)

(b) Criteria for Adjustment. This standard may be adjusted if consistent with the criteria of EC 9.8030(3)(g).

(a) Required Materials. Massed Landscape Standard (L-7) requires the installation and maintenance of all of the following:

1. Planting linear or non-linear vegetation listed in subparagraphs 2 through 5 of this subsection along the full length of the designated landscape area.

2. 2 canopy trees per 100 linear feet along arterial and collector streets;

3. 5 under-story trees per 100 linear feet along arterial and collector streets.

4. 60 shrubs per 100 linear feet along arterial and collector streets; and

5. Living plant materials covering a minimum of 70 percent of required landscape area within 5 years of planting.

(b) Criteria for Adjustment. This standard may be adjusted if consistent with the criteria of EC 9.8030(3)(h).
