Sections:
18.25.005 Dimensions – Use of compact spaces – Surfacing.
18.25.010 Cooperative off-street parking.
18.25.020 Minimum off-street parking requirements.
18.25.030 Parking lot landscaping and screening.
18.25.005 Dimensions – Use of compact spaces – Surfacing.
(1) Standard size parking spaces must be a minimum of nine feet by 20 feet in size.
(2) Compact parking spaces must be a minimum of eight feet by 16 feet in size.
(3) Compact spaces may not exceed 50 percent of the required number of parking spaces.
(4) All parking lots shall make adequate provisions for traffic aisles (e.g., 24-foot-wide travel aisle for perpendicular (90 degree) parking).
(5) All parking spaces shall be surfaced with gravel, pavement, or pervious or porous pavers. (Ord. 939 § 6, 2016).
18.25.010 Cooperative off-street parking.
(1) Cooperative use of required parking spaces may occur where two or more uses on the same or separate sites are able to share the same parking spaces because their parking demands occur at different times, for example, residential and office uses. Cooperative use of required parking spaces is allowed if the following documentation is submitted in writing to the planning manager as part of a permit application:
(a) The location and number of parking spaces that are being shared;
(b) An analysis showing that the peak parking times of the uses occur at different times and that the parking area will be large enough for the anticipated demands of both uses; and
(c) A legal instrument such as an easement or deed restriction that guarantees access to the parking for both uses.
(2) When feasible, cooperative off-street parking may be used to achieve up to 100 percent of required parking. In a mixed-use development, residential surface parking may only be provided through the use of NPMC 18.25.010. (Ord. 1054 § 2, 2023; Ord. 888 § 2 (Exh. A), 2012; Ord. 743 § 3, 2004).
18.25.020 Minimum off-street parking requirements.
(1) For purposes of defining off-street parking, floor area of each level of a building shall exclude areas devoted to storage, restrooms, corridors, hallways, entries, stairways, elevators, decks, equipment, utility rooms and kitchens not to be occupied by clientele, and other areas for utility purposes not connected with general conduct of business for which office or sales space is provided.
(2) Off-street parking areas shall contain the minimum number of parking spaces stipulated in Charts 18.25.020a (General Residential Parking Standards) and 18.25.020b (General Nonresidential Parking Standards), plus adequate stopping or parking areas for service vehicles. A use that is similar to any of the below-referenced uses shall adhere to the minimum parking requirements for the referenced use or uses. The planning manager shall determine the minimum parking requirements for service vehicles and for a use that is not referenced in this section.
(3) LID best management practices (BMPs), including but not limited to green stormwater infrastructure, shall be used for parking lot design and construction, unless site and soil conditions make LID infeasible as determined by the public works department. LID BMPs shall be designed and constructed in accordance with the LID Technical Guidance Manual for Puget Sound (current edition) and approved by public works.
(4) Required parking for uses in Charts 18.25.020a and 18.25.020b shall use the provisions of NPMC 18.25.010 to exceed the minimum spaces required standards in these charts.
(5) Only 50 percent of the parking minimum spaces are required if a development project constructs portions or all of a planned pedestrian or bicycle facility or improves an existing pedestrian or bicycle facility, both as listed in the comprehensive plan transportation element under “Walking and Biking” and in the current TIP. The specific design and implementation details shall be addressed in a development agreement.
(6) Commercial parking that is part of cooperative off-street parking shall be clearly identified and visible.
