B.    The city planner shall have the authority to waive specific requirements or impose additional requirements in unique or special circumstances to ensure the fulfillment of the stated purpose of this chapter and to allow for flexibility and innovation of design. Special circumstances or unique conditions shall be reviewed with the city planner prior to submittal of a landscape plan. Examples of special conditions might include:

1.    Preservation of unique wildlife habitat;

2.    Preservation of natural or native areas;

3.    Compliance with special easements;

4.    Renovation of existing landscaping;

15.47.020 Landscape plan approval.

A.    A building permit shall not be issued until the landscaping plan has been approved.

B.    At the time of development plan review, the city planner shall review specific landscape requirements with the owner or his representative.

C.    The city planner may require the applicant to post a bond or a security deposit in the amount of one and one-quarter (1 1/4) times or one hundred twenty-five percent (125%) of the estimated cost of landscaping. The bond or security deposit will be returned to the applicant upon the city planner’s inspection of the installed landscaping and upon written notice that the provisions of the landscaping plan have been met. (Ord. 919 § 7, 2021; Ord. 627 (part), 1999)

15.47.030 Failure to complete required landscaping—Inspection.

A.    Prior to the issuance of any construction permits for a project, a bond payment, in an amount determined by the city planner based on current price per square foot of standard plantings, shall be submitted to the city to guarantee installation of the required landscaping. Required landscaping shall be installed within six (6) months of the date of final certificate of occupancy. If the requirements are not met in the allotted time, the city shall use the bond to complete the landscaping work.

C.    The city planner may inspect the landscaping upon request of the project manager or business owner or at any time after the six (6) month expiration date. (Ord. 919 § 7, 2021; Ord. 627 (part), 1999)

15.47.040 General landscape requirements for all zones.

A.    All parking areas of over twenty thousand (20,000) square feet shall have a minimum of ten percent (10%) of the parking area, maneuvering area and loading space landscaped as a means to reduce the barren appearance of the lot and to reduce the amount of stormwater runoff. Fifty percent (50%) of the perimeter landscaping, required adjacent to property lines, may be calculated as part of the ten percent (10%) figure.

B.    All ingress or egress easements which provide corridors to the subject lot, not adjacent to a public right-of-way, shall be considered the same as a public right-of-way. Landscape requirements for easement corridors shall be the same as those required adjacent to public rights-of-way.

C.    All outside storage areas shall be screened by fencing and landscaping a minimum of five (5) feet in depth unless it is determined by development plan review that such screening is not necessary because stored materials are not visually obtrusive. The five (5) foot deep landscaped area can occur within the street right-of-way abutting the property line.

D.    All portions of a lot not devoted to building, future building, parking, storage or accessory uses shall be landscaped in a manner appropriate to the stated purpose of this chapter.

E.    All required landscaping areas shall extend to the curb line or the street edge. A crushed rock path in lieu of landscaping may be required where appropriate as determined by the city planner.

F.    Required landscape areas which are inappropriate to landscape due to the existence of rail lines or other features shall be relocated, first, to another lot line, or second, to an equal-sized area in another portion of the lot, to be determined by the city planner upon review with the owner or developer.

G.    Bark mulch, gravel or other nonvegetative material shall only be used in conjunction with landscaping to assist vegetative growth and maintenance or to visually complement plant material. Nonvegetative material is not a substitute for plant material.

H.    Required landscape areas shall be provided with adequate drainage.

I.    Slopes shall not exceed a three (3) to one (1) ratio (width to height), in order to decrease erosion potential and assist in ease of maintenance except when occurring naturally.

J.    The perimeter of all parking areas which abut residential zones or uses shall be landscaped to a minimum depth of three (3) feet with Type II landscaping unless otherwise provided by this chapter. A six (6) foot high solid wood or equivalent fence is also required. Substitute fencing, including but not limited to chain link fence with slats, may be approved by the city planner upon application of the developer and adjacent residential property owners when such fencing shall provide buffering consistent with the purpose and intent of this chapter. The term “adjacent residential property,” for purposes of this section, means abutting property, and lots immediately adjacent to abutting property, and shall not mean property across a public road, a private street or a landscape buffer of similar width.

K.    Landscaping shall not conflict with the safety of those using adjacent sidewalks or with traffic safety. Safety features of landscaping shall be discussed at the time of development plan review, if necessary.

L.    Quantity, arrangement, and types of plants installed shall be appropriate to the size of the required landscape area and purpose of planting area as noted in Section 15.47.050 pertaining to types of landscaping.

M.    All trash containers shall be screened from abutting properties and streets by a one hundred percent (100%) sight-obscuring fence or wall and appropriate landscaping.

N.    Landscaping shall be placed outside of sight-obscuring or one hundred percent (100%) sight-obscuring fences unless it is determined by the city planner that such arrangement would be detrimental to the stated purpose of this chapter. (Ord. 919 § 7, 2021; Ord. 627 (part), 1999)

C.    Action Upon Noncompliance.

1.    Upon the failure, neglect or refusal of any owner or agent so notified to perform the required maintenance within the time specified in the written notice, or within fifteen (15) days after the date of such notice if the notice is returned to the city by the postal service because of inability to make delivery thereof; provided, the notice was properly addressed to the last known address of the owner or agent, the city planner or his or her designated representative is authorized and empowered to cause the required maintenance to be done and provide for payment of the cost thereof, with the cost to be collected or taxed against the property affected as provided in this section.
