Planning Commission Agenda Packet 09092026

P26-0704, 1047 Serpentine Lane, Suites 400 and 500 Planning Commission 6 of 8 educational uses are regulated based primarily on the number of employees and students. Places of public assembly are generally regulated by seating capacity or the amount of floor area available for seating. These standards demonstrate that the PMC recognizes that parking demand varies significantly depending on how a space is occupied and used. Given the limited hours of operation, the limited occupancy of the proposed facility, and the absence of large classes, spectator seating, assembly events, or other activities that could substantially increase attendance, staff believes that an occupancy-based parking determination is appropriate for the proposed use. The proposed maximum parking demand of approximately 10 spaces would represent less than one-quarter of the 44 parking spaces available on the site, leaving approximately 34 spaces available for the remaining approximately 11,472 square feet of building ar ea. The remaining businesses within the building consist primarily of office, commercial , industrial, and assembly uses, including RS Calibration Services, Inc. and St. Innocent Church (which operates Saturday evenings and Sundays). These uses have parking characteristics typical of the surrounding business park and are not known to generate unusually high parking demand during typical weekday business hours of approximately 8:00 a.m. to 5:00 p.m. The operating characteristics of the proposed indoor recreation facility would further reduce the potential for parking conflicts. Participation would occur through scheduled training sessions and/or appointments, allowing the number of people using the facility to be controlled. The maximum occupancy of 10 people would always apply, thereby providing a predictable upper limit on parking demand. In addition, portions of the proposed operating hours would fall outside typical weekday business hours, when parking demand from other businesses in the building generally decreases. The shared nature of the parking lot also allows available spaces to be used efficiently by the various tenants, rather than reserving individual spaces for particular businesses. PMC Section 18.88.060 similarly recognizes that sites with multiple uses may benefit from differing operating characteristics and parking demand, including circumstances in which uses have different operating periods. Accordingly, the parking analysis should consider the site's combined operational characteristics rather than whether every tenant will experience its theoretical peak parking demand simultaneously. For additional context, if the site's 44 parking spaces were allocated in proportion to tenant floor area alone, the 5,088-square-foot indoor recreation facility would correspond to approximately 13.5 parking spaces. The anticipated maximum demand of approximately 10 spaces would therefore remain below the facility's proportional share of the site's parking supply. Conversely, approximately 30.5 spaces would proportionately serve the remaining building area. Although parking is not formally assigned in this manner, this comparison further demonstrates that the proposed use is not expected to consume a disproportiona te share of the available parking. Staff is unaware of any existing parking problems at the subject site. Based on the 44 shared parking spaces available, the proposed maximum occupancy of 10 pe ople, the scheduled nature of the use, the operating characteristics of the other tenants, and the ability of all tenants to utilize the shared parking supply, staff believes that adequate parking is available to accommodate the proposed indoor recreation facility and the existing uses within the building
