C. Expansion of Existing Development. Existing buildings, which are expanded by one thousand square feet or existing parking and circulation areas which are expanded by five thousand square feet after the effective date of the ordinance codified in this title shall comply with the requirements of this chapter.
D. Change in Use. When an existing residential use of land or structure or any part thereof is changed to a commercial or industrial use, landscaping shall be provided to meet the requirements of the new use.
E. Waiver Request. The community development director may waive all or portions of the additional landscaping requirement for an existing development or use. The applicant shall make a written request for waiver and indicate the reasons for not being able to comply with the requirements of this chapter. A waiver shall only be issued for that portion of the required landscaping which will create a significant spatial hardship based on the physical characteristics of the existing development. (Ord. 2209 § 2 (part), 2008).
20.50.030 General landscaping requirements.
A. Landscaping Plan. A landscaping plan shall be required for any residential developments with more than five units, commercial, and industrial developments and the plan shall include the following:
1. The site plan shall be accurately drawn, using an appropriate engineering or architectural scale, and showing the following:
a. Boundaries and dimensions of the site;
b. Location and identification of all streets, alleys and easements on or abutting the site;
c. Proposed location and dimensions of all on-site buildings;
d. Location of existing and proposed driveways and parking surfaces, curbs, and sidewalks;
e. Proposed landscaping including location, species and size at time of planting;
f. Existing vegetation in general and identifying all evergreen and deciduous trees four inches and greater in diameter measured at twenty-four inches above grade level;
g. Details of any proposed architectural barrier;
h. Existing and proposed topography at a maximum of five-foot contours;
i. Irrigation and Drainage. The landscape plan shall include an irrigation and drainage plan. An irrigation plan is required to ensure that the planting will be watered at a sufficient level for plant survival and healthy growth. Alternative irrigation systems, including the reliance on drought-tolerant plantings which meet the intent of this section, may be considered by the director.
B. Undeveloped Areas. Undeveloped areas of a lot which are not required to be landscaped by other requirements of this chapter shall be planted with groundcover or left with native vegetation.
C. Open Area Landscaping. All areas which are utilized to meet landscaping requirements shall be landscaped in a manner appropriate to the stated purpose of this chapter. Appropriate landscaping may include trees, shrubs and groundcover.
D. Groundcover. Groundcover shall be planted and maintained within all required landscaping areas. Groundcover shall consist of plantings that will achieve complete coverage within two years. Lawn may be used as groundcover. As a general rule, groundcover must be planted on eighteen- to thirty-six-inch triangular centers in order to assure complete coverage within two years. Groundcover is not required within the dripline of any shrub or evergreen tree and within a two-foot radius of a deciduous tree trunk. Additionally, groundcover may be excluded from the area under shrubs or trees with a spacing of two feet or less. The spacing shall be measured from the dripline of shrubs and evergreen trees and from a two-foot radius from a deciduous tree trunk.
E. Bark, Mulch and Gravel. Bark, mulch, gravel or other similar nonvegetative material shall only be used to assist vegetative growth and maintenance within landscaping areas. Nonvegetative material shall not be a substitute for, or interfere with, required vegetative groundcover.
F. Slopes in Landscaping Area. Slopes within landscaping areas shall not exceed a three to one ratio (width to height) in order to decrease erosion potential and to facilitate maintenance.
G. Clear Line of Sight. Landscaping shall be designed, planted and maintained in a manner that ensures pedestrian, bicycle and vehicular safety. Shrubs and groundcover within and adjacent to parking lots and circulation areas shall not exceed thirty-six inches in height when necessary to provide for a clear line of sight for vehicular drivers. The groundcover height shall be measured from adjacent parking or circulation pavement surface.
H. Safety Equipment. Landscaping around fire and safety equipment such as fire hydrants shall be designed, planted and maintained in a manner that ensures adequate access and use. Groundcover around fire and safety equipment shall be of a nonclimbing variety.
I. Tree and Shrub Standards.
1. All deciduous trees shall have a minimum of one-and-one-half-inch caliper trunk. All evergreen trees shall be a minimum of eight feet in height.
2. All shrubs shall be a minimum of five-gallon size.
3. Planting areas shall be separated from parking areas and driveways by a six-inch concrete curb.
4. Landscaped areas shall be maintained in a neat, clean, and orderly condition. This is meant to include proper pruning, lawn mowing, weeding, removing of litter, fertilizing, replacing of dead plants, and regular watering of all landscaped areas.
5. Natural vegetation, groundcover, stands of trees or shrubs existing prior to development of the site may be acceptable to meet the landscaping requirement. Areas which have been cleared of vegetation or groundcover prior to or during construction, and which are not otherwise developed, shall be landscaped with trees, shrubs and suitable groundcover. Suitable materials for groundcover are those which permit rainwater infiltration of the soil and may include sod, ivy, bark, noncompacted gravel and the like.
J. Landscaping Islands and Peninsulas. To the greatest extent practicable, landscaped areas shall be dispersed throughout the impervious surface area. Truck parking and loading spaces are exempt from this requirement.
K. Curb/Curb Edge. Planting areas shall be fully protected by curbs as a means of preventing injury to plants from pedestrian or vehicular traffic and to prevent landscaping material from entering the storm drainage system. No trees or shrubs shall be planted within three feet of a curb edge. Groundcover is required within such three-foot area. (Ord. 2209 § 2 (part), 2008).
20.50.040 Landscape installation and maintenance requirements.
A. Installation. The landscaping required by this chapter shall be installed either prior to receiving a temporary or permanent occupancy certificate permit, or within one hundred eighty days of occupancy. The landscaping shall be planted in accordance with the approved plan.

Such maintenance shall include the landscaping required within a public right-of-way.
C. Deferment. The installation of landscaping may be deferred for up to six months from the date an applicant receives a temporary or permanent certificate of occupancy. A bond shall be submitted to the city in order to ensure the completion of the landscaping in accordance with the approved plan. It shall be the responsibility of the applicant and the property owner to contact the director upon completion of the landscaping work and request an inspection.
D. Performance Bond Amount and Type. The type of bond shall be approved by the director and must be submitted on forms supplied by the city. The approved bond shall be posted with the community development department prior to the issuance of a building permit.
