Ms. Minnie Dhaliwal, Planning Supervisor January 25, 2017 2160566.30 Page 2 of 4 The proposal is to build a new 2,515- square foot building for daily administrative use by the bus drivers. The building will provide needed facilities for the drivers and support the daily transportation operations for the District. The building will include a conference /training room, break room, two offices, storage room, mechanical closet, janitorial closet, lobby, and restrooms. Site improvements will result in 17 bus parking spaces (1 additional) and 25 standard vehicle parking spaces (4 less). A new 5 -foot wide painted pedestrian pathway will be provided to the building from S.1281h Street. Vehicular access to the site will be the same as before, with a separated entry and exit point from S. 128th Street. The proposed building will be subject to design review. Perimeter landscaping will be provided per the City of Tukwila's Municipal Code. A 5 -foot wide Type I landscape buffer is provided adjacent to East Marginal Way. In this area some trees were removed with permission. We are not proposing to remove any other trees or vegetation and would be happy to meet at the site with the City's Urban Forester to review the landscaping proposal. We have proposed a partial visual barrier in keeping with the Police Department's request. The other perimeter buffers are located within 50 feet of LDR -zoned property and provide a 10 -foot wide Type II buffer. Portions of the buffer are existing and portions are enhanced. Conditional Use Criteria The property is zoned Neighborhood Commercial Center (NCC). The new building onsite will primarily be used as office space, which is permitted outright in the NCC zone. However, the City has determined that because the overall use of the site is to support a school - related use, and schools are a Conditional Use per Table 18 -6 of the Tukwila Municipal Code (TMC), a Conditional Use Permit (CUP) is required. Responses below show consistency with the criteria for a CUP, as required per TMC 18.64.050: The proposed use will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity. The purpose of a CUP is to allow uses that may not be appropriate within a given zoning district, but may be permitted subject to conditions and mitigation measures that protect health, safety, and welfare, and ensure compatibility with surrounding uses. The new transportation facility and associated site improvements do not adversely affect health, safety, and welfare, nor do they present an incompatible use. The existing use on the site is a bus storage area for the Tukwila School District, which provides a needed public service to the City by storing the buses used to transport the District children to their schools. This use will remain unchanged. A new 2,515- square foot building is proposed on the site for the comfort and use of the bus drivers and to support the daily operations. This building will not generate any sort of public nuisance, such as noise or odor, and traffic will not change from current levels. The primary use of the new building is office space, which is permitted outright in the NCC zone. 2. The proposed use shall meet or exceed the same standards for parking, landscaping, yards and other development regulations that are required in the district it will occupy.
