(Ord. 28-05 § 1.02; Ord. 10-21 § 1; Ord. 2026-01 § 3)
The purpose of landscaping requirements for parking facilities is to protect and promote the public health, safety, and general welfare by reducing wind and air turbulence, heat and noise, and the glare of automobile lights; to act as a natural drainage system and ameliorate stormwater drainage problems; to reduce the level of carbon dioxide and return pure oxygen to the atmosphere; to prevent soil erosion; to provide shade; to conserve and stabilize property values and to otherwise facilitate the creation of a convenient, attractive and harmonious community; to relieve the blighted appearance of parking facilities; and to generally preserve and promote a healthful and pleasant environment.
A. 
Design Criteria. Landscape areas shall be located in such a manner as to divide and break up the large expanses of pavement; divide and define driveways, parking stalls and corridors; limit cross-taxiing; delineate and separate pedestrian and vehicular traffic and screen parking facilities from abutting properties. Planting areas and landscaping shall be reasonably dispersed throughout the parking lot with the interior dimensions of such areas being sufficient to protect the landscaping materials planted therein and to ensure proper growth. The primary landscaping materials used shall be trees, which provide shade or are capable of providing shade at maturity. Shrubbery, hedges and other planting materials shall be used to complement the tree landscaping, but shall not be the sole contribution to the landscaping. Effective use of earth berms and existing topography is encouraged as a component of the landscape plan. Use of native shrub-steppe plantings for required landscaping is acceptable at trailheads or gravel parking areas located within or adjacent to identified shrub-steppe areas and will satisfy these design criteria if the resulting product satisfies Washington Department of Fish and Wildlife standards for priority habitat.
B. 
Interior Coverage. A minimum of five percent of the interior of a parking facility shall be landscaped. Landscaping which is required for screening along the perimeter of any lot and border plantings adjacent to buildings upon which a parking lot abuts shall not be considered as part of the interior coverage requirements. Parking spaces abutting a perimeter for which landscaping is required by other requirements of this section shall not be considered as a part of the interior of the parking facility.
1. 
For off-street parking facilities providing 10 or fewer parking stalls as required by RMC § 23.54.020, and in areas zoned for industrial use, the interior coverage requirements stated herein shall not apply.
2. 
Any interior landscape area shall contain a minimum of 50 square feet, shall have a minimum dimension of at least five feet, and shall include at least one tree with the remaining area adequately landscaped with shrubs, ground cover or other approved landscaping materials not to exceed three feet in height.
3. 
Trees shall number not less than one for each 100 square feet of required interior coverage.
C. 
Perimeter Coverage Adjacent to Abutting Properties. A minimum landscape strip of five feet in width shall be required along any side of a parking facility that abuts adjoining property that is not a public right-of-way when such facilities will not be entirely screened visually by an intervening building or structure; provided, that when such parking facility abuts and is designed in coordination with a parking facility on the adjoining property such landscape strip shall not be required abutting such adjoining parking facility; and provided further, that in areas zoned for industrial use, the perimeter coverage requirements stated herein shall not apply.
1. 
Perimeter landscape strip shall be planted or installed with a wall, hedge, or other durable landscape barrier to form a continuous screen between the parking facility and abutting property. The height of any such barrier shall be not less than three feet and no more than six feet.
2. 
Trees shall also be planted for each 40 linear feet and shall have at least 25 square feet of planting area.
3. 
Where a proposed parking facility abuts an existing hedge, wall or other durable landscape barrier on an abutting property, said existing barrier may be used to satisfy the landscape barrier requirements of this subsection; provided, that said existing barrier meets all applicable standards of this section.
D. 
Perimeter Coverage Adjacent to Public Right-of-Way. A minimum landscape strip of 10 feet in width shall be required along any side of a parking facility that abuts a public right-of-way, excluding dedicated alleys; provided, that in areas zoned for industrial use, the perimeter coverage requirements stated herein shall not apply.
1. 
Perimeter landscape strip shall be planted or installed with a wall, hedge, or other durable landscape barrier of at least three feet in height which shall be placed along the parking facility side of such landscape strip.
2. 
If such a durable barrier is of nonliving material, one shrub for each 10 linear feet shall be planted along the street side of such barrier; provided, that if the shrubs are of sufficient height at the time of planting to be readily visible over the top of such barrier, they may be planted along the parking facility side of such barrier. The remainder of the landscape strip shall be landscaped with ground cover or other approved landscape treatment excluding pavement.
3. 
At least one shrub for each 50 square feet shall be provided.
4. 
Trees shall also be planted for each 30 linear feet or portion thereof and shall have at least 50 square feet of planting area.
5. 
No tree, as measured from its center, shall be located within 10 feet of a street light standard, or within five feet of a fire hydrant, a vehicular driveway, or a public sidewalk.
E. 
Landscaping Material. Landscaping materials used to achieve the design criteria in conformance with provisions of this section shall conform to the following standards:
1. 
Trees shall be species having an average mature spread of crown of greater than 15 feet and shall be a minimum of six to eight feet in height and have a diameter at breast height (dbh) caliper of at least one and one-half inches at planting. Diameter at breast height is measured at four and one-half feet from average grade within six feet of the tree trunk so as not to include mounding at the tree base. Trees having an average mature spread of crown less than 15 feet may be substituted by grouping the same so as to create the equivalent of a 15-foot crown spread. Tree species whose roots are known to cause damage to public roadways or other public works shall not be planted closer than 12 feet to such public works, unless the tree root system is completely contained within a barrier being a minimum of five feet deep and five feet wide.

Grass areas may be sodded, plugged, sprigged or seeded, except that solid sod shall be used in swales or other areas subject to erosion; and provided, that in areas where other than solid sod or grass seed is used, nurse grass seed shall be sown for immediate effect and protection until coverage is otherwise achieved.
6. 
Ground covers used in lieu of grass shall be planted or installed in such a manner as to present a finished appearance, and if of living material, shall complete coverage within 12 months after planting.
F. 
Driveway and Street Intersections. To ensure that landscape materials do not constitute a safety hazard, a vision clearance triangle (VCT) shall be provided at all intersections of public rights-of-way and driveways in accordance with public works requirements in Chapter 12.11 RMC.
G. 
Curbing. In order to protect the landscaping materials planted and to ensure proper growth, all planter areas shall be separated from contiguous property, including parking stalls, by curb stops. Such curb stops shall be of Portland cement or shall otherwise conform to Standard Specifications for Municipal Public Works Construction (APWA Standards), or shall be approved by the city engineer.
H. 
Installation. All landscaping shall be installed in a workmanlike manner and according to accepted good planting procedures. All elements of landscaping, exclusive of plant material other than hedges, shall be installed so as to meet all other applicable ordinances and code requirements.
I.

1. 
The zoning administrator shall inspect all landscaping and no certificates of occupancy or similar authorization will be issued unless the landscaping meets the requirements herein provided.
2. 
In those cases where landscaping cannot be safely installed due to the time of year without jeopardizing living landscape material, or for other good cause, a temporary certificate of occupancy may be issued for a period of six months; provided, that the property owner, lessee, or duly authorized agent shall furnish satisfactory assurances guaranteeing installation of the approved landscaping.
J. 
Landscaping of Existing Lots. Any reconstruction of a building or structure or lot area, including off-street parking facility, consisting of increases of 50 percent or greater of the existing building lot area or parking facility shall be subject to the standards specified herein. In such cases, the existing parking facility, as well as any new facility, shall be improved in accordance with the standards stated herein; provided, that:
1. 
In instances where existing parking spaces are used to achieve compliance, the parking facility shall be considered to comply with the parking standards and requirements of RMC § 23.54.020; provided, however, that no more than 10 percent of the total number of required spaces may be removed for purposes of providing landscape areas.
2. 
No alteration of existing building nor acquisition of additional land to increase the lot area shall be required in order to bring the property into compliance with the landscaping requirements herein.
(Ord. 28-05 § 1.02; Ord. 20-14 § 1.04; Ord. 10-21 § 1; Ord. 2026-01 § 3)
Where literal interpretation of the provisions of RMC § 23.54.140 or special conditions or circumstances exist which would create a hardship in the development and/or maintenance of the landscaping, or where easements, pedestrian ways, trail systems, existing vegetation, continuity of design concepts within a zoning district, parking design, emergency vehicle access, or other matters of public design, safety or welfare would be promoted, the administrative official may adjust the provisions of RMC § 23.54.140, provided it is determined that such an adjustment will not be contrary to the public interest and will be in keeping with and preserve the intent of RMC § 23.54.140.

Adjustment of Landscaping Standards. Adjustments from the specific requirements of this section shall be reviewed and approved in accordance with the provisions of RMC § 23.54.150.

Landscaping of Developed Industrial-Zoned Property. On developed industrially zoned properties whenever any structure(s) is altered, expanded or reconstructed in a manner which increases the total gross floor area of structure(s) located on the lot by 50 percent or more, or whenever a change of use occurs to an existing structure or facility which increases the required number of parking stalls by 50 percent or more over what was required of the prior use, landscaping of the lot shall be provided in accordance with the provisions of this subsection.
1. 
The square footage of landscaped area provided pursuant to this subsection shall be the same as would be required if a new facility were constructed on the parcel.
2. 
Landscaping shall be located on the property in accordance with provisions for new industrial facilities.

3. 
No alteration of existing structures, acquisition of additional land, or removal of existing asphalt/concrete walks, drives or parking areas shall be required in order to bring the property into compliance with landscaping requirements herein.
