18.58.040 Parking requirements for common facilities.

The amount of off-street parking required in LFPMC 18.58.030 may be reduced, by an amount to be determined by the planning department, when common parking facilities for two or more buildings or uses are designed and developed as one parking facility, provided;

A. The total parking area exceeds 5,000 square feet.

B. The amount of the reduction shall not exceed 10 percent for each use, except that the reduction may exceed 10 percent when:

1. The reduction is based on cooperative use of parking facilities when the time during which the cooperative uses operate are not conflicting;

2. The normal hours of operation are separated by at least one hour;

3. The total number of off-street parking spaces in the common facility is not less than the sum of the required parking spaces for the various uses computed separately for which the hours of operation overlap.

C. A covenant or other acceptable contract between the cooperating property owners is approved by the planning department which cannot be amended without the consent of the department.

D. If the conditions under which the reduction in parking requirements was approved are violated, the affected property owners must provide a remedy satisfactory to the planning department or provide the full amount of required off-street parking, in accordance with the provisions of this chapter, within 90 days of notice of the violation by the director or his designee. (Ord. 773 § 3, 1999)

Parking will not be permitted in entrances and exits. (Ord. 773 § 3, 1999)

18.58.070 Access.

Where the side street is available, access to the parking area must be made from that side street or lower classified street. Access to arterial and collector streets should only be done when no other reasonable access alternative exists.

(Ord. 773 § 3, 1999)

18.58.080 Landscaping, pathways and amenities.

A. Purpose. To realize the city’s vision and reflect community values, all aspects of our city should ensure that the natural environment is celebrated. This includes the trees, lands, buildings and connections, as well as the spaces where vehicles park. Incorporating natural elements to provide shade, assist in managing surface water, and enhance the ecology of the location both reflect the character of the city and play an important role in combating the effect of urban heat islands that contribute to climate change.

B. Applicability.

1. New projects or redevelopment projects exceeding 50 percent of the fair market value of the parking lot must comply with these regulations in their entirety.

2. Redevelopment projects not exceeding 50 percent of the fair market value of the parking lot must comply with these regulations for all new or replaced portions of the parking lot.

3. Maintenance of existing parking lots that does not include altering the footprint of the parking lot, such as grind and overlay or restriping projects, must comply with these regulations where possible.

C. Landscaping. Parking lot landscaping is required as follows:

1. Perimeter Parking Lot Landscaping.

a. Adjacent to Roadways. Parking lots adjacent to roadways shall include a 10-foot-wide planting bed meeting the requirements for Type 3 landscaping set forth in LFPMC 18.62.080; except trees can be clustered or staggered to improve visibility near driveways and a 30-foot break in the required tree coverage is allowed adjacent to permitted signage. Refer to Figure 18.58.080-1.

Figure 18.58.080-1: Landscaping between large parking lots and adjacent streets.

b. Adjacent to Residential Uses. Parking lots adjacent to residential uses or zones must include the following additional screening measures:

i. A post-and-beam fence, decorative metal fence, or similar fence with minimum four-inch openings consistent with residential character and quality; and

ii. A 10-foot-wide planting bed meeting the requirements for Type 1 landscaping set forth in LFPMC 18.62.080.

c. Adjacent to Other Uses. Parking lots adjacent to nonresidential uses on a separate lot must provide a 10-foot-wide planting bed meeting the requirements for Type 2 landscaping set forth in LFPMC 18.62.080. This requirement can be waived by the director if adjacent lots are under common ownership with the subject of the proposal.

d. Adjacent to Buildings. Parking lots adjacent to buildings shall include a five-foot-wide planting bed meeting the requirements of Type 3 landscaping set forth in LFPMC 18.62.080.

e. Adjacent to Streams. Parking lots adjacent to streams as defined in Chapter 16.16 LFPMC shall include a 20-foot-wide planting bed meeting the requirements of stream buffer landscaping set forth in LFPMC 18.62.080. Where this provision conflicts with other landscaping requirements, this provision shall prevail.

2. Interior Parking Lot Landscaping. Surface parking lots must be landscaped to break up large areas of asphalt and provide visual relief as follows:

a. Landscaping must be provided within surface parking lots at a rate of 20 square feet per parking stall. Landscaping must be designed and maintained to provide clear sight distance between three and one-half feet and eight feet above the existing street or private access road grade. Surface parking lot landscaping must be planted as follows:

i. Deciduous trees shall be planted at a rate of one tree per every seven stalls;

ii. Shrubs shall be planted no more than four feet apart; and

iii. Groundcovers shall be planted no more than 24 inches apart. Turf is not permissible as a groundcover in surface parking lot landscaping.

b. Landscape islands must be placed no further than 10 parking stalls apart and at the end of each parking row. Landscaping strips may be placed between rows of parking stalls. Landscape islands and strips must be a minimum of four feet wide and have an area of at least 75 square feet. Refer to Figure 18.58.080-2.

Figure 18.58.080-2: Parking lot landscaping.

c. Landscape islands or planters must be surrounded by a standard vertical curb or similar barrier to protect the plantings from vehicle overhang. Gaps in the curb are permitted for stormwater drainage.

3. Low Impact Development. Except in landscape buffer areas adjacent to a “stream,” as defined in Chapter 16.16 LFPMC, parking area landscaping shall be used for low impact development best management practices or treatment best management practices as approved by the public works director pursuant to the stormwater management manual adopted in LFPMC 16.24.010, unless technically infeasible. The requirements for plant sizes and spacing in this section may be relaxed for bioretention facilities when supported by recommendations provided by an arborist, landscape architect, or other qualified professional.

5. Perimeter landscaping in addition to the requirement in subsection B of this section;

6. Permanently installed and maintained public art. This is satisfied if the pedestrian pathway uses unique paving treatments; or

7. Other element that encourages pedestrian activity and creates a welcoming pedestrian environment, as approved by the director. (Ord. 1219 § 1, 2021; Ord. 773 § 3, 1999)
