Traffic Impact Report prepared by DKS Associates, Oct. 2018 20 UncIlPaasuff ert Lisle- PH raft Staff Report [1.8-0100 FINDINGS PROJECT DESCRIPTION King County Metro Transit is proposing to redevelop the former Group Health office park, which is adjacent to their existing South Bus Base campus, for a new interim bus base. The proposed facility will be used for Metro Transit bus parking, operations and maintenance. The site is proposed to remain in use as an interim bus base for approximately five years. The proposed Interim office structures include modular buildings. This facility is intended initially for diesel/hybrid buses but may eventually be converted for charging and maintenance of battery buses. Until that occurs, diesel/hybrid coaches stationed at the interim base will be fueled and washed at the adjacent South Base. A new internal connection east of the parking garage will provide internal circulation on site through the South base, primarily for buses departing via the SR599 on - ramp. Additionally, a new driveway is proposed on the west from E Marginal Way S for Metro employee vehicles entering and exiting the parking garage. The majority of the site will be graded flat, paved and striped for coach parking. Metro expects the facility to have a capacity of up to 126 coaches. The existing three story parking garage will be retained and used for employee parking. VICINITY/SITE INFORMATION Site Description The project site is located on one lot, approximately 543,900 square feet in size, on the east side of E Marginal Way at the intersection of S 124th St. Existing Development The site currently contains the former Group Health office park which included a combination of office, manufacturing, and warehouse uses. No uses currently exist onsite. Surrounding Land Use Surrounding land uses to the north and west of the site consist primarily of manufacturing, warehouse, and office uses; and are zoned MIC/L or MIC/L. SR 599 runs along the eastern boundary of the property. To the south are properties zoned Low Density Residential (LDR) district; roughly half a dozen homes are located on these LDR properties at the top of a wooded hill and are located no closer than 500' to the development area. Environmentally Sensitive Areas Areas categorized as Class 2 and Class 3 slopes are located on the south side of the property. No development is proposed within these areas. Topography The site slopes down from the southern boundary line to a flat area that makes up most of the area of the parcel. The hillside goes from approximately 30' in elevation at its base to 150' at its highest point. The hillside is entirely vegetated and is not proposed to be developed in any form. The remainder of the site is relatively flat, with elevations between 25-30'. 21 Unct assliiffiftKi Us( .^ Pell rat Staff IRE^paou 1'1'9M^d Mdi ( p(uuu9q t i, Aerial of Parcel 7340600480 11111111I1111wNl0ou11uH Vegetation Vegetation on the site consists of the wooded hillside to the south and perimeter and parking lot landscaping associated with the former Group Health office park. As part of the development proposal, the majority of the site (not including the hillside) is to be reconfigured resulting in the removal of most of the existing formal landscaping. KC Metro has proposed replacing any trees removed as part of the new development. Access Existing access to the site is from E Marginal Way S in the form of two vehicle access points. These existing access points are proposed to be used for buses -only, with a third proposed access point to be used for employee -vehicle access to the parking garage. REVIEW PROCESS The property on which the South Interim Base is proposed is zoned Manufacturing Industrial Commercial — Light (MIC/L). Table 18-6 of the Tukwila Zoning Code lists the land uses allowed by district and designates whether the land use is permitted outright, accessory, conditional, or unclassified. Within the MIC/L district, a Mass Transit Facility is designated as an unclassified use, requiring review and approval of an Unclassified Use Permit according to the criteria contained in Chapter 18.66 of the Zoning Code. Additionally, per TMC 18.36, Administrative Design Review is required for all new developments within 300' of residential districts. The Director of Community Development shall issue a decision on the administrative design review application after the City Council decision on the Unclassified Use Permit. 22 UncIlPaasuff ert Lisle- PH raft Staff Report [1.8-0100 UNCLASSIFIED USE PERMIT In the following discussion, the review criteria for approval of an Unclassified Use Permit (per TMC 18.66.060) are in bold, followed by staff's evaluation of project consistency with the criteria. The applicant's response to the criteria are contained in the project narrative as Attachment D to this report. Decision Criteria — Unclassified Use Permit 1. Where appropriate and feasible, all facilities shall be undergrounded. All permanent on site utility facilities and connections to the existing utilities in the city right of way in E Marginal Way S will be undergrounded. The applicant's project narrative explains that for the bus base facilities, "it is not appropriate nor is it feasible to place the buses, offices, and vehicles maintenance area of the bus base underground in the manufacturing industrial center light zone." All employee parking is proposed to be located in an existing above ground parking garage onsite. 2. The proposed use will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity. The applicant's project narrative describes how the project design will ensure that potential impacts to surrounding properties will not occur, including the following: "Re -development of the site for a bus base will follow the development standards of the MIC/L zone. Provisions of the zoning code are held to be the minimum requirements adopted for the promotion of the health, safety, morals, or the general welfare of the community per TMC Tukwila Municipal Code 18.04.010. King County employee parking at the existing parking garage will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity as the volume and frequency of parking access to the garage from the public right of way will not exceed the volume and frequency of prior parking and access when it was used for employee parking by Group Health." Neighboring residential properties to the south are largely buffered by a vegetated hillside approximately 120' in total elevation. Any offsite impacts including noise and light should be effectively reduced by this buffer. Additionally, as provided in a response to City of Tukwila comments to King County's SEPA Determination of Non -Significance dated December 14, 2018, the applicant has noted that impacts from emissions related to the bus parking facilities should be limited: "While the addition of up to 126 buses plus additional employee and non -revenue vehicles will increase emissions locally, the increase in emissions is not anticipated to raise to a level of significant impact. Although the new facility will have a capacity of 126 buses, Metro's programmed utilization of the site is limited to approximately 90 buses. The number won't occur upon initial activation of the South Interim Base. Initial base utilization likely will be approximately 40 buses and the numbers will phase up over time as Metro advances its fleet acquisition plan. The South Interim Base assigned fleet will be the newest diesel electric hybrid buses in Metro's fleet. These buses will be best performing from the standpoint of fuel use and emissions. Additionally, Metro is electrifying its fleet with initial deployment of zero emission long range battery electric buses being planned for the South Base Campus starting as early as 2021. It is a Metro policy as directed in King County Metro's 'The Book 2018 Operator Rules and Procedures' that, with few exceptions, operators are required to turn off coach (bus) engines immediately upon arrival at a terminal such as South Interim Base and all other layover points. Additionally, as is outlined above, Metro plans to deploy its newest diesel electric 23 Und aasuff ed Ust PH raft Staff Report 6 L .8-0100 hybrid buses at South Interim Base which should address potential immediate and short term air quality impacts. Potential long term air quality impacts will be addressed by Metro's eventual deployment of an all -electric fleet." A Traffic Impact Report prepared October 2018 was also provided by DKS Associates on behalf of King County Metro (Attachment I). The study evaluated the transportation impacts associated with the construction of the proposed South Interim Base project and provided the following conclusions: "The South Interim Base is projected to generate approximately 159 fewer total AM peak hour trips and 175 fewer total PM peak hour trips than the Group Health Facility. All of the study intersections meet the City of Tukwila's operating standards for all future scenarios. The new site will have a total of four access points: A new employee garage access, a bus -only exit, a bus -only entrance, and a new internal connection to the South Base. The northern project site will be effectively narrowed and will only be used by exiting buses. This intersection will receive signal and striping modifications but will remain largely unchanged." The City of Tukwila Public Works Department concurs with the findings of the report. Metro is proposing a lighting plan as part of their Administrative Design Review permit proposal that works to limit light trespass on neighboring properties as well: "Exterior lighting design approach will adhere to recommended practices of the IESNA Lighting Handbook, Tenth Addition, the Washington State Non- residential Energy Code, and minimum lighting levels stipulated for safety of workers by WAC 296-800- 210. Additionally, the following design strategies will be utilized to ensure minimal light trespass and aesthetic integration with structures and overall visual themes consistent with site use: 1) Lighting equipment will be 4000K LED source with high CRI exclusively, 2) new lighting equipment will be full cut-off design with no illuminance at angles higher than 90-degrees above nadir, 3) Luminaires and poles will be dark bronze color, or custom color to match building finishes, 4) lighting poles will be located well in -board of property line boundaries to limit light spill onto adjacent properties, and 5) exterior lighting design will be modeled to ensure performance using pt-by-pt calculations available in Lighting Analyst AG132 software. Particular focus to limit light trespass will be made in regards to impacts on adjacent residential zoned properties." 3. 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. The Manufacturing Industrial Center - Light District includes regulations related to setbacks, building height, landscaping, and the required number of parking spaces. The project meets or exceeds these requirements, as detailed below: The Site Plan in Attachment A demonstrates the project's conformance with setback requirements of the MIC/L zone, including the 20-foot front yard setback, 15-foot side yard setback for the southern property boundary that is within 50' of the LDR district, and 0-foot rear yard setback. The building height of the Vehicle Maintenance Building is proposed to be 33'6" at its highest point and the Operations Building is proposed to be less than 20', well within the 45-foot height limit for the MIC/L zone. Figure 18-7 of the Tukwila Zoning Code lists the number of required parking spaces for automobiles, based on the use of a site. However, the number of required parking spaces for a Mass Transit Facility is not specified in Figure 18-7. King County Metro has estimated the following number of employees will be located onsite: 24 Und aasuff ed List- .^ PH raft Staff Report [1.8-0100 • 103-203 Coach Operators • 70 Non -Coach Operators (Mechanics, Office Staff, etc.) Total: 143-273 employees. Metro is proposing to provide 575 non-ADA and 12 ADA stalls onsite for 587 total parking spaces, mostly within the existing parking garage. This provision of parking is well above the most conservative employee parking demands provided by Metro. TMC 18.52.030, Table A contains the landscaping requirements in the MIC/L district. A minimum of 15 feet of landscaping is required within the front yard setback area and southern side yard setback area due to these yards being within 50' of LDR district. No landscaping is required for the northern side yard. To accommodate the types of uses in MIC/L district, side and rear yard landscaping may be clustered to permit truck movement or to accommodate other uses commonly found in this district if the criteria in TMC 18.52.100.D are met. The "Type" of landscaping required dictates the quantity of trees, shrubs, and groundcover required along the perimeter of a development site. Type II landscaping is required on all perimeter areas of this site. The proposed landscaping shown in the Landscape Schematic Design plan sheet of Attachment B includes approximately 15 feet of front yard landscaping, greater than 15 feet of side landscaping, and 5 feet of rear yard landscaping meeting the Type II landscaping requirements for plant materials and quantities. Fifteen feet of landscaping per parking stall is also required by this section of the code. The site includes additional landscape area to achieve the parking lot landscaping requirement. 4. The proposed development shall be compatible generally with the surrounding land uses. Metro has provided the following response: "Bus base use is comparable to other industrial permitted outright uses such as truck terminal, vehicle maintenance, heavy equipment repair, and office. Office and vehicle maintenance use is proposed on the site to support the operation, maintenance and use of the bus fleet." Adjacent Metro properties have been in use for many years, with operations dating back to pre - annexation from King County into the City of Tukwila. The proposed Interim Bus Base will be compatible with these surrounding land uses. 5. The proposed development shall to the maximum extent feasible be consistent with and promote the goals, objectives, and policies of the Comprehensive Land Use Policy Plan and applicable adopted area plans. Following are the relevant policies of the Tukwila Comprehensive Plan (applicant responses are in quotations, staff responses follow): Comprehensive Plan Policy 4.13.2 Improve retention of trees on steep slopes. "The south vegetated hillside will be retained. This area serves as a buffer between the LDR zone south of the hillside and minimizes any potential noise or light impacts associated with the bus base use." City staff concurs with applicant's response. Additionally, Metro will be undertaking restoration on part of the hillside where an overhanging structure is to be demolished as part of the project's demolition permit, D18-0258. This restoration will comply with the planting and restoration requirements set forth in Chapter 18.45: Environmentally Sensitive Areas. 25 Und aasuff ed Ust PH raft Staff Report L .8-0100 Comprehensive Plan Policy 7.8.7 Ensure that urbanization and development do not negatively impact current neighborhood noise levels and adhere to Environmental Protection Agency and Federal Aviation Administration standards. Project will comply with Tukwila Municipal Code Chapter 8.22: Noise. No variances from the noise ordinance are requested as a part of the development. Additionally, King County Metro's 'The Book 2018 Operator Rules and Procedures' directs that operators are required to turn off coach (bus) engines immediately upon arrival at a terminal such as South Interim Base and all other layover points (Attachment I), effectively reducing potential noise impacts from idling engines at the site. Comprehensive Plan Goal 11.1 Support for existing industrial activities in the Manufacturing/Industrial Center and development of new industrial activity, in order to maximize the employment and economic benefits to the people of Tukwila and the region, while minimizing impacts on residential neighborhoods. "The use is adjacent to the existing bus base that provides bus service and employment to the community. Additionally, the use is separated from a residential neighborhood to the south by a steep, vegetated hillside which minimizes any potential noise, light or other impacts associated with the use." City staff concurs with the applicant's response. Comprehensive Plan Policy 11.1.5 Allow uses that are commonly associated with manufacturing and industry, including those directly supporting such activity, such as offices and laboratories, while limiting unrelated uses. "The bus base use is industrial in nature and is an extension of the existing bus base immediately north of the site." City staff concurs with the applicant's response. Comprehensive Plan Policy 11.1.9 Reduce reliance on the single -occupancy vehicle for transportation of employees in and out of the MIC. "The use supports provision and maintenance of buses that provide an alternative to single occupant vehicle use for employees in and out of the MIC and other land use zones in the city and county. Potential transportation impacts resulting from the proposed use and site redevelopment are analyzed and documented in the King County Metro Transit Interim South Base Transportation Impact Analysis dated September 2018. This detailed evaluation determined that the interim base will generate fewer vehicle trips during peak hours than the former Group Health facility on the project site and the proposed project should not result in any adverse transportation impacts to the study area. The adjacent residential area south of the project site will not be directly impacted by future bus traffic because all additional transit service will exit southbound onto SR599 directly from South Base's existing on -ramp by way of a new internal connection between the existing bus base and site or northbound onto E Marginal Way. Returning buses will return from the north on E Marginal Way to return to the bases. Therefore, both out- bound and returning coaches will bypass the nearby residential area.." City staff concurs with the applicant's response. 26 Und aasuff ed Ust PH raft Staff Report L .8-0100 6. The proposed unclassified use shall, to the maximum extent feasible, mitigate all significant adverse environmental impacts on public and private properties. Full consideration shall be given to: a) alternative locations and/or routes that reduce or eliminate adverse impacts; and b) alternative designs that reduce or eliminate adverse impacts. King County Metro considered several other sites for base expansion needs as part of an Alternatives Analysis report prepared September 22, 2016 (Attachment E). The following criteria set forth by Metro were considered in the analysis: "Metro will need to acquire property that is immediately adjacent to the bus base and situated appropriately in order to enable the actions described above. The property must have buildings that are usable for Metro functions or has land suitable for development for those uses, and it must not have environmental features that limit buildable space to an unacceptable level. The property must have a willing seller or must have a low risk of a challenging and time-consuming condemnation or relocations; this is in order to avoid significant risk of controversy and delays that could hinder Metro's ability to expand facilities at a quick -enough pace to keep up with rising demand for bus service." Three alternatives were explored: 1) No Action Alternative, 2) Group Health Property Alternative (preferred), 3) Integrate East Properties Alternative. It was ultimately found that the No Action Alternative and the Integrate East Properties Alternative would not meet the needs for Metro's expansion. Metro provided the following reasoning: The No Action Alternative would constrain Metro's ability to expand base capacity at South Base and other bases in Metro's system. Metro must expand base capacity in order to improve the declining level of service at its bases. Expansion at South Base is a key element of that. The No Action Alternative is not a preferred alternative. The Integrate East Properties Alternative presents several issues affecting Metro use of the site and results in potentially significant impacts related to acquisition, relocation, access and safety. The property is not adjacent to the main South Base facility and would be less efficient, functionally, than the Group Health Property Alternative and it is likely too far to relocate South Base operations; warehouse space is insufficient. The property is not for sale and condemnation appears to be likely. Condemnation can take a significant amount of time and can be controversial and time-consuming. The Integrate East Properties Alternative would likely require relocating existing businesses which could prove to be controversial and time-consuming. A signal may need to be installed at the intersection of South 120th Place and East Marginal Way South in order to improve safety, particularly for Metro employees crossing East Marginal Way South to access the main South Base facility. The No Action Alternative will not meet Metro's need for interim or long-term base expansion needs. In conclusion, the Integrate East Properties Alternative is not a preferred alternative as an interim or long- term solution to Metro base expansion needs due to issues related to acquisition, relocation, access and safety, and location relative to South Base. However, the site may have future potential due to its size, zoning and existing structures, and it may become a more viable option at a future date for long-term expansion needs. Metro's preferred alternative for current base expansion purposes is the Group Health Property Alternative because it has no significant issues related to acquisition or use by Metro, and it is ideally located for Metro's base expansion purposes. The Group Health Property Alternative considers impacts on public and private properties from noise, 27 Und aasuff ed Ust PH raft Staff Report 1.0 L .8-0100 light, and aesthetics, and has included mitigation measures in its design to address them, see Attachment E for full analysis. 7. In the event that a proposed essential public facility of a countywide or statewide nature creates an unavoidable significant adverse environmental or economic impact on the community, compensatory mitigation shall be required. Compensatory mitigation shall include public amenities, incentives or other public benefits which offset otherwise unmitigated adverse impacts of the essential public facility. Where appropriate, compensatory mitigation shall be provided as close to the affected area as possible. This criterion is not applicable to this project. 8. For uses in residential areas, applicants shall demonstrate that there is no reasonable nonresidential alternative site for the use. This criterion is not applicable to this project as use is located entirely within the Manufacturing Industrial Center — Light district. 9. For uses in residential areas, applicants shall demonstrate that the use provides some tangible benefit for the neighborhood. This criterion is not applicable to this project as use is located entirely within the Manufacturing Industrial Center — Light district. 10. Secure community transition facilities shall meet the following additional criteria: This criterion is not applicable to this project as it is not a secure community transition facility. CONCLUSIONS - UNCLASSIFIED USE PERMIT The project has been designed to mitigate potential impacts to surrounding properties and improvements in the vicinity related to noise, lighting, and aesthetics. The project meets or exceeds the development standards within the Manufacturing Industrial Center - Light district. The proposed development is compatible with surrounding land uses. Proposed setback and building heights are similar in scale to nearby structures, and landscaping along the perimeter of the project property enhances the site and provides a buffer for single-family homes to the south. The proposed development is consistent with the Comprehensive Land Use Plan, including goals and policies within the Natural Environment, Residential Neighborhoods and Land Use, and Manufacturing/Industrial Center elements. King County Metro considered several alternative project sites in vicinity of the South Base. Other sites were ultimately deemed too costly and/or would have had negative impacts on existing businesses/tenants. The completed project will result in a secure facility, designed to blend in with the surrounding neighborhood and screened from adjacent properties by landscaping on all sides.

After construction of interim base facilities, the site will remain in use as an interim bus base for approximately five years. Interim office structures will include modular buildings. Building 1 — Operations Modular Building — 1 story - 10,380 sq. ft. building area (offices, dispatch, report area, classrooms, exercise room, locker room, lounge, restrooms) Building 2 Vehicle Maintenance Building: Modular building area and Pre -Engineered building area -1 story 25,764 sq. ft. building area 33'6" ridge height (bus service & inspection bays, locker room, lounge, restrooms) Building 3 Hostler Shack — Office Modular Construction — 1 story - 320 sq. ft. building area Building 4 Existing Parking Garage — 3 story 67,000 sq. ft./ floor 600 parking stalls approx. 25'9" height This facility is intended initially for diesel/hybrid buses but may eventually be converted for charging and maintenance of battery buses. However, until that occurs, diesel/hybrid coaches stationed at the interim base will be fueled and washed at the adjacent South Base. A new internal connection east of the parking garage will provide internal circulation on site through the South base primarily for buses departing via the SR599 on -ramp, and a new driveway is proposed on the west from E Marginal Way S for Metro employee vehicles entering and exiting the parking garage. The majority of the site will be graded flat, paved and stripped for coach parking. Metro expects the facility will have a capacity of up to 126 coaches. s i2.arki r t faun gLa iliflJlllef, fir s% 4 r 4r //Ga/ 4444 FKISDIND HYDRA, //. ,rr a/ r !nn vf'V ! ip�l�jJh !iS III rii a.. 11� I, I i 'oiw�j 91 it n ,.,��v �..�nwno i ;mp4plP�oppp uuumi;!!IIIIIII!!IIIIIIIIIIIIIIIIII IIullllll �,t� plel, ppIIIV���lldlllllfll ludo IIIIIIIIII m 111111JJJJfJJJJJuuuuuuuuuuuuuuuuuuuuuuuuuuuuu1, 411 plIIIlluill�ulpIIIIIIIUIIII�IuVIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIpJIpJJJ))URIJJ)))))UJJJJJ))))))J)j)Uljjgg JJJJJppppuuuuml III miimiml, III°°"'' J! ! 111111 I111 Nh NN1 ,,,, ,,,,, IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII 55 Attachment D Please discuss development consistency with the nine (9) decision criteria presented below. Use additional pages as needed. Please consult the Comprehensive Plan for policies related to your development. Note that more than one category of policies may apply. TMC 18.66. 060 CRITERIA FOR UNCLASSIFIED USES 1. Where appropriate and feasible, all facilities shall be undergrounded. Bus base facility It is not appropriate nor is it feasible to place the buses, offices, and vehicles maintenance area of the bus base underground in the manufacturing industrial center light zone. Utility facilities All permanent on site utility facilities and connections to the existing utilities in the city right of way in E Marginal Way S will be undergrounded. Existing garage use The garage for King County employees is an existing above ground building. To accommodate space for existing buses queuing in bus drive aisles on the base, parking for existing CSC component supply center employee vehicles will be relocated to the garage. 2. The proposed use will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity. Bus base use Re -development of the site for a bus base will follow the development standards of the MIC/L zone. Provisions of the zoning code are held to be the minimum requirements adopted for the promotion of the health, safety, morals, or the general we/fare of the community per TMC Tukwila Municipal Code 18.04.010. Existing garage use King County employee parking at the existing parking garage will not be materially detrimental to the public we/fare or injurious to the property or improvements in the vicinity as the volume and frequency of parking access to the garage from the public right of way will not exceed the volume and frequency of prior parking and access when it was used for employee parking by Group Health. 56 Attachment D 3. 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. Bus base use Bus base site development will follow the development standards of the MIC/L zone. Existing garage use Parking use of the existing parking garage structure meets development regulations for yard setback, yard landscaping. A portion of the existing standard parking spaces will be restriced to provide the ratio ofADA parking stalls required per current state, local and federal regulations. 4. The proposed development shall be compatible generally with the surrounding land uses. Bus base use The proposed bus base use is a secured and restricted facility that provides parking for up to 126 buses that will depart and terminate between off site mass transit stations and bus stops. Bus base use differs from mass transit station use as the bus base is not providing public access to transit nor public parking for mass transit. A mass transit station typically provides public access and public on -site parking whereas a bus base is limited to public transit employees and infra structure that support internal base operations and maintenance. Bus base use is comparable to other industrial permitted outright uses such as truck terminal, vehicle maintenance, heavy equipment repair, and office. Office and vehicle maintenance use is proposed on the site to support the operation, maintenance and use of the bus fleet. Existing garage use Parking use of the existing parking garage by bus base employees is compatible because there is similar use parking existing in the surrounding area of bus base employee parking to the north and existing office and industrial warehouse parking to the east. 5. The proposed development shall to the maximum extent feasible be consistent with and promote the goals, objectives, and policies of the Comprehensive Land Use Policy Plan and applicable adopted area plans. 57 Attachment D The bus base with employee parking use is consistent with the following Comprehensive Plan goals and policies Comprehensive Plan Element 11: The Manufacturing Industrial Center is a major distribution hub well -served by automobile, truck, air, rail, and water transportation facilities. Comprehensive Plan GOAL 11.1 Support for existing industrial activities in the Manufacturing/Industrial Center and development of new industrial activity, in order to maximize the employment and economic benefits to the people of Tukwila and the region, while minimizing impacts on residential neighborhoods. The use is adjacent to the existing bus base that provides bus service and employment to the community. Additionally, the use is separated from a residential neighborhood to the south by a steep, vegetated hillside which minimizes any potential noise, light or other impacts associated with the use. Comprehensive Plan Policy 11.1.5 Allow uses that are commonly associated with manufacturing and industry, including those directly supporting such activity, such as offices and laboratories, while limiting unrelated uses. The bus base use is industrial in nature and is an extension of the existing bus base immediately north of the site. Comprehensive Plan Policy - Improve Transportation Flow Work with other governmental agencies to address transportation problems. Comprehensive Plan Policy 11.1.9 Reduce reliance on the single -occupancy vehicle for transportation of employees in and out of the MIC. Comprehensive Plan Policy Implementation Strategies Regional/rapid rail service to the MIC Work to have a multimodal transportation center Continued support of agencies developing other programs to reduce dependence on the single occupancy vehicle New east -west transit routes serving the MIC and other areas in Tukwila Support alternative commercial routes in and out of the MIC The use supports provision and maintenance of buses that provide an alternative to single occupant vehicle use for employees in and out of the MIC and other land use zones in the city and county. Potential transportation impacts resulting from the proposed use and site redevelopment are analyzed and documented in the King County Metro Transit Interim South Base Transportation Impact Analysis dated September 2018. This detailed evaluation determined that the interim base will generate fewer vehicle trips during peak hours 58 Attachment D than the former Group Health facility on the project site and the proposed project should not result in any adverse transportation impacts to the study area. The adjacent residential area south of the project site will not be directly impacted by future bus traffic because all additional transit service will exit southbound onto SR599 directly from South Base's existing on -ramp by way of a new internal connection between the existing bus base and site or northbound onto E Marginal Way. Returning buses will return from the north on E Marginal Way to return to the bases. Therefore both out -bound and returning coaches will bypass the nearby residential area. King County Metros Community Connections program and the City of Tukwila are in the beginning stages of a project with a goal of expanding transportation options for Tukwila residential neighborhoods Comprehensive Plan Policy 4.13.2 Improve retention of trees on steep slopes. The south vegetated hillside will be retained. This area serves as a buffer between the LDR zone south of the hillside and minimizes any potential noise or light impacts associated with the bus base use. 6. The proposed unclassified use shall, to the maximum extent feasible, mitigate all significant adverse environmental impacts on public and private properties. Full consideration shall be given to: a. alternative locations and/or routes that reduce or eliminate adverse impacts; and b. alternative designs that reduce or eliminate adverse impacts. King County conducted an analysis of alternative locations and impacts and concluded that the site is a suitable location for the bus base parking use with no significant impacts. Supporting the bus base benefits public, city and county residents and commuters by providing expanded bus service capacity to meet a growing need in the area. An internal connection between the property and the existing Metro operations base to the north will reduce the number of times that buses must exit onto East Marginal Way S to move to the base to the north for maintenance functions that are not housed on the subject property. 7. In the event that a proposed essential public facility of a countywide or statewide nature creates an unavoidable significant adverse environmental or economic impact on the community, compensatory mitigation shall be required. Compensatory mitigation shall include public amenities, incentives or other public benefits which offset otherwise unmitigated adverse impacts of the essential public facility. Where appropriate, compensatory mitigation shall be provided as close to the affected area as possible. The parking use and the bus base use is not an essential public facility as defined by RCW 47.06.140 but has been determined by the city to fall under the definition of mass transit facility: 59 Attachment D TMC 18.06.568 Mass Transit Facilities "Mass transit facilities" shall include structures and infrastructure for public or private transportation systems having established routes and schedules such as transit centers, commuter and light rail facilities, both rail lines and stations, monorails, people movers and other similar mass transit facilities but not including incidental improvements such as bus stops. 8. For uses in residential areas, applicants shall demonstrate that there is no reasonable nonresidential alternative site for the use. N/A; the use is located in a Manufacturing Industrial zone. 9. For uses in residential areas, applicants shall demonstrate that the use provides some tangible benefit for the neighborhood. N/A; the use is located in a Manufacturing Industrial zone. 60 Attachment E Analysis of Properties adjacent to South Base to support Base Capacity Expansion Prepared by Gary Kriedt, Senior Environmental Planner KC Metro, Design and Construction September 22, 2016 Proposal The proposal is to expand onto property adjacent to South Base to address interim and long-term transit base network capacity needs while planning begins on a new bus base in south King County and to facilitate near -term expansion of Central/Atlantic Base. This expansion will also enable Metro to improve functional space needs of the work groups that support all the bases. Current System -Wide Bus Base Capacity King County has experienced unprecedented growth in recent years with one million more people and 850,000 more jobs expected by 2040. This growth comes with a corresponding increase in demand for bus services. To meet this increase in demand, Metro envisions the following service and capital investments (outlined in Metro's Long Range Plan): • 70 percent more bus service by 2040, from 3.5 million hours of service to 6 million hours, increasing the peak -period mode share from 12 percent today to 24 percent in 2040 and bringing frequent service to within a half -mile of 70 percent of the county's population; • 20 new RapidRide lines, some of which are funded through the Move Seattle levy. • Increase in the bus fleet by approximately 550 buses by 2040. This will require the expansion of bus base capacity at existing bus bases and through construction of up to two or three new bus bases; Metro's seven bus bases support an average of 200 buses each, and have both operations and maintenance facilities. However, Metro's bus bases are currently at or near maximum capacity which limits the ability to add more buses to the fleet. Metro will need two or three additional bus bases to meet demand through 2040. And since a new bus base can take up to 15 years to plan, acquire property, design, and construct, Metro is looking at interim solutions to provide more capacity at existing bases. Bus base capacity planning looks at performance in terms of parking capacity and maintenance capacity using Level of Service (LOS), similar to traffic LOS, where LOS A indicates optimal performance, LOS C a mid -range "tight but manageable" performance, and LOS E a poor level of performance. Recent capacity modeling (March 2016) indicates each base's current LOS level per fleet assignment: Base Coaches Cap Cap Factor ILOS C ILOS D Atlantic 265 106% Parkong 251 304 Central 179 95% Parkung 188 224 Ryerson 2111 1128 /0 Maint. 164 191 BeIllevuie 145 1IO2%0 Parkun-g 140 158 East 222 107% Parkun-g 208 233 North 204 115% Parkong 177 2.02.

All other bases are at over -capacity for bus parking, while Ryerson is more constrained by its maintenance capacity. Future System -Wide Bus Base Capacity The latest (Feb 2016) modeling of system -wide base capacity shows that the current fleet surpasses optimal available bus base capacity levels, and the demand for base capacity will increasingly outpace supply. At present, some bases are already operating at LOS D. The system would continue to be at Draft 2,100 2,000 1,900 1,800 1,400 1,300 1,200 1,100 1,000 Fleet versus Capacity: 2014-2040 1.

Future base capacity is shown in the chart below. Metro's focus for adding capacity is at Atlantic, Central, and South Base. The other bus bases have limited potential to expand due to topography, natural or built features (e.g., rivers or sports stadiums), local zoning and comprehensive plan restrictions, or formal agreements restricting expansion (North Base). Base Capacity Needs Planning —September 22, 2016 page 2 62 Attachment E South Base Expansion Plans Metro's goal for South Base is to increase the capacity of core functions which are bus parking, bus maintenance, and fueling/washing. Metro intends to increase bus parking capacity at South Base from about 266 to about 440 buses, add six more maintenance bays, and add new fuel and wash lanes. To achieve this, Metro plans to relocate non -core support functions from the South Base site to other locations to create space for expanding core capacity. Non -core support functions to be moved include Operations, Safety, Training, and the Component Supply Center (CSC) which is for parts distribution and major rebuilds. Metro is seeking to move the non -core functions at South Base to property immediately adjacent to the base since those functions need to be as close to the base as possible in order to maintain efficiency, particularly operations. Metro plans to demolish the existing CSC structure at South Base to increase bus parking, a core function of the base, and will construct a new CSC structure on Metro's South Facilities site, on the west side of East Marginal Way South. An increase in capacity at South Base will improve conditions throughout Metro's operating base system as Metro adjusts the allocation of buses between bases and as Metro continues planning for further additions to system -wide base capacity. Alternatives Analysis Metro will need to acquire property that is immediately adjacent to the bus base and situated appropriately in order to enable the actions described above. The property must have buildings that are usable for Metro functions or has land suitable for development for those uses, and it must not have environmental features that limit buildable space to an unacceptable level. The property must have a willing seller or must have a low risk of a challenging and time-consuming condemnation or relocations; this is in order to avoid significant risk of controversy and delays that could hinder Metro's ability to expand facilities at a quick -enough pace to keep up with rising demand for bus service. The most viable property options at South Base include a property adjacent to and south of South Base and two properties adjacent to South Facilities on west side of East Marginal Way South. The property adjacent to South Base, the Group Health property is owned by Bank of China and is currently for sale with active offers. The other two properties, Intergate East, owned by Sabey Corporation, will be considered together as a unit because their total acreage and total existing structural square footage is comparable to the Group Health property. Other parcels in the vicinity do not meet the location and buildability criteria, described above, and are not under consideration. So, Metro has two potentially - viable alternatives, the Group Health Property Alternative and the Intergate East Property Alternative. A third option, No Action, will not allow Metro to expand sufficiently to meet future increasing demand. The analysis below discusses natural and built environment topics that are included in FTA's NEPA Categorical Exclusion worksheets. No Action Alternative Description: The No Action Alternative would involve no acquisition of property for expansion at South Base. It would maintain current conditions with few options for expanding capacity at South Base, and it could constrain plans for Atlantic/Central Base expansion. This would hamper Metro's ability to relocate support functions and expand bus parking and maintenance capacity in the Metro operating base Base Capacity Needs Planning —September 22, 2016 page 3 63 Attachment E system. As described above, Metro needs to expand system -wide capacity, and expansion at South Base is a key element of that. The No Action Alternative is not a preferred alternative. Group Health Property Alternative Description: Group Health property, 12400 East Marginal Way South, PIN 7340600480, owned by Bank of China, 12.4 acres. The property is currently for sale and has active offers. The property has a two- story office -warehouse building (over 270,000 sf total) and one 600-stall garage plus 200 vehicle surface parking. Group Health had previously planned to vacate the property by July 2017, so relocation costs are not associated with the property. Office space total: 131,968 sf Storage/warehouse total: 110,175 sf Industrial engineering space: 30,079 sf Location, Zoning, Land Use: The site is at 12400 East Marginal Way South in Tukwila, WA, immediately south, and adjacent to, Metro's existing South Operating Base. Access to South Base would be direct because the properties are adjacent to one another. Location is ideal for relocating South Base operations to free up space at the base for bus parking and maintenance, and warehouse space is sufficient. Surrounding land uses include the following: bus base to the north (zoned MIC/L), SR 599 to the east, neighborhood commercial to the south (zoned NCC, Neighborhood Commercial Center), and East Marginal Way South to the west with MIC/L and H zoning on the west side of East Marginal Way South. The proposed use of the site is consistent with existing zoning. No land uses in the vicinity would be affected by Metro use of the Group Health property, and site is not affected by neighboring uses. Additionally, Metro would not change the type of use of the site. Traffic: Metro use of the site is not expected to change current traffic conditions substantially and existing roadways have adequate capacity to handle anticipated traffic from the site. A traffic signal is located at the entryway to the property at East Marginal Way South. The project does not include any roadway modifications. The exact nature and type of improvements by Metro is not yet known, but any changes to the site by Metro would need local City of Tukwila review, including review of traffic impacts, if any, prior to the approval of permits. This will ensure that potential traffic impacts will be adequately addressed. Aesthetics: Metro use of the site will not affect aesthetics in the project area (use would remain consistent with existing zoning and with surrounding uses. Air Quality: Metro use of the site will not affect air quality in the project area. The site is in a Maintenance Area for Carbon Monoxide. Environmental Justice: The property is located in Census Tract 272 which, compared to King County averages, has average median household income, below average poverty level, and above average percent people of color. The property acquisition is intended to accommodate expansion of Metro operational capacity which will assist with providing expanded transit service to minority and low- income populations. Hence, the acquisition will not have a disproportionately high and adverse impact on minority or low-income populations. Metro has not conducted outreach related, specifically, to the property acquisition, but has made extensive efforts with regard to Metro's Long Range Plan, which this acquisition helps to implement. Floodplains: The site is not within the 100-year floodplain. Hazardous Materials: Metro has obtained a Phase I Environmental Site Assessment for the site dated June 27, 2006, and is pursuing an update of that information which is not expected to significantly change the results of the 2006 report. The site had a leaking underground storage tank which was Base Capacity Needs Planning —September 22, 2016 page 4 64 Attachment E removed in 1994 followed by groundwater monitoring and a No Further Action letter from the Washington State Department of Ecology. Due to the age of the structure(s), asbestos is expected to be in building materials as well as lead paint. Several small business hazardous waste generators are located across East Marginal Way South. Noise and Vibration: Noise and vibration is not a factor. Nearby uses will not affect the site, and Metro use of the property will not cause significant noise or vibration impacting other properties. Historic and Cultural Resources: No known resources in the vicinity or on the site. Biological: No known biological resources in the vicinity including endangered species and critical habitat. Recreational: No known recreational resources in the vicinity. Seismic and Soils: The site has a steep slope/landslide prone area on the south side of the property. The slope is recognized as a Class 2 slope by the City of Tukwila where landslide potential is high, because the slope is approximately 50%. The slope is vegetated, has a retaining wall, and has no evidence of instability. The slope is not affected by neighboring uses. The slope does not appear to present any limitations to use of non -slope areas of the property. Soils at the site consist of urban full overlying alluvial deposits, mostly medium to very dense silty gravelly sand. Bedrock is at a depth of approximately 22 feet. Water Quality: No known water quality issues related to the site or to Metro's use of the site. Wetlands: No known wetlands on the site aside from the detention pond in the northwest corner of the site. Construction Impacts: Future work at the site will likely include improvements that accommodate Metro operational and administrative functions; however, the exact nature and type of those improvements is not yet known. Improvement at the site to accommodate Metro's use would not directly impact adjacent properties. However, construction vehicles would increase local traffic on East Marginal Way S which may cause slight delays to vehicles accessing properties west of East Marginal Way S in the project vicinity. Cumulative and Indirect Impacts: No significant cumulative or indirect impacts. Property Acquisition/Relocations: The property is currently for sale and purchase by Metro would not be controversial. Use by Metro would not result in relocations because the current tenant, Group Health, had already made plans to vacate the property which led to the property being put on the market. Group Health plans to vacate by June, 2017, Energy: Metro's use of the site is unlikely to increase energy use at the site, although this has not been quantified because exact uses have not been identified. Metro selects highly energy -efficient equipment and it is possible that energy use at the site would go down after Metro improves and occupies the property. Public Involvement: Metro has not conducted outreach related, specifically, to acquisition of this property. Metro has made extensive efforts with regard to Metro's Long Range Plan, which this acquisition helps to implement. Mitigation Measures: The exact nature and type of future improvements by Metro is not yet known, but any changes to the site by Metro would need local City of Tukwila review and approval which may include mitigation measures in addition to measure employed by Metro. Construction phase mitigation measures would include best management practices to protect surface water, groundwater, and other resources. Operations measures would be included during design to ensure potential impacts are minimized. Base Capacity Needs Planning —September 22, 2016 page 5 65 Attachment E Permitting/Local Review: The exact nature and type of improvements by Metro is not yet known, but changes to the site by Metro would likely need local City of Tukwila review. Zoning is consistent with likely proposed uses of the site. Intergate East Properties Alternative Description: Intergate East properties, 3311 and 3417 S 120th Place, PINs 1023049078 and 1023049069, both owned by Sabey Corporation, 7.59 and 6.23 acres respectively totaling 13.82 acres. The properties are not for sale. The properties have two office/warehouse/manufacturing buildings (over 230,000 sf total), surface parking, no parking garage. Office space: 21,323 sf Storage/warehouse total: 52,701 sf Engineering space/data center: 36,228 sf Industrial engineering space: 30,079 sf Manufacturing: 94,596 sf Location, Zoning and Land Use: The site is immediately adjacent to, and south of South Facilities which is west of South Base and East Marginal Way South. Location is not ideal for relocating South Base operations but may be appropriate for relocating other functions; however, warehouse space is insufficient. Surrounding land uses include the following: bus base to the north (zoned MIC/L), East Marginal Way South to the east, industrial business park to the south (zoned MIC/H), and SR99 right-of- way to the west. The proposed use of the site is consistent with existing zoning. Traffic, Access and Safety: Access to the site is via South 120th Place which is owned by Sabey Corporation. South Facilities uses this roadway as well as industrial business park uses south of the Intergate East Properties. Continued shared use of S 120th Place for the industrial business park would present difficulties with regard to safety and security for a Metro use at the site, and Metro would likely consider sole use of South 120th Place. However, removal of access via S 120th Place for uses south of Intergrate Properties could prove to be controversial. Metro use of the site is not expected to change current area -wide traffic conditions substantially and existing roadways have adequate capacity to handle anticipated traffic from the site. The project would not likely include any significant physical roadway modifications, except possible installation of a signal at the intersection of South 120th Place and East Marginal Way South in order to improve safety, particularly for Metro employees crossing East Marginal Way South. Improvements by Metro would need local City of Tukwila review, including review of potential traffic impacts, prior to the approval of permits. This will ensure that potential traffic impacts will be adequately addressed. Aesthetics: Same as Group Health Property Alternative. Metro use of the site will not affect aesthetics in the project area (use would remain consistent with existing zoning and with surrounding uses). Air Quality: Same as Group Health Property Alternative. Metro use of the site will not affect air quality in the project area. The site is in a Maintenance Area for Carbon Monoxide. Environmental Justice: Same as Group Health Property Alternative. The property is located in Census Tract 272 which, compared to King County averages, has average median household income, below average poverty level, and above average percent people of color. The property acquisition is intended to accommodate expansion of Metro operational capacity which will assist with providing expanded transit service to minority and low-income populations. Hence, the acquisition will not have a disproportionately high and adverse impact on minority or low-income populations. Metro has not conducted outreach related, specifically, to the property acquisition, but has made extensive efforts with regard to Metro's Long Range Plan, which this acquisition helps to implement. Base Capacity Needs Planning —September 22, 2016 page 6 66 Attachment E Floodplains: Same as Group Health Property Alternative. The site is not within the 100-year floodplain. Hazardous Materials: The Intergate East properties have businesses that are small generators of hazardous waste. Due to the age of the structures on the site, asbestos may be in building materials as well as lead paint. Several small business hazardous waste generators are located on properties south of the Intergate East properties. Noise and Vibration: Same as Group Health Property Alternative. Noise and vibration is not a factor. Nearby uses will not affect the site, and Metro use of the property will not cause significant noise or vibration impacting other properties. Historic and Cultural Resources: Same as Group Health Property Alternative. No known resources in the vicinity or on the site. Biological: Riverton Creek, which flows on the western portion of the west parcel of Alternative 2, is a relatively high quality stream and is considered good salmon habitat. No other known wetlands are on the site. Recreational: Same as Group Health Property Alternative. No known recreational resources in the vicinity. Seismic and Soils: City of Tukwila maps show that the site has a steep slope/landslide prone area on the east side of the easternmost property. However, that area appears to be landscaped and is not likely a landslide area. The landscaped slope are does not appear to present any limitations to use of other areas of the site. The site also has steep slope with landslide potential on the western portion by SR 99 right-of-way. Soils at the site are expected to be the same as the South Facilities site which are urban fill overlying stream deposits and consolidated glacial deposits. Water Quality: Same as Group Health Property Alternative. No known water quality issues related to the site or to Metro's use of the site. Wetlands: Riverton Creek flows on the western portion of the west parcel of Alternative 2. The creek appears to flow in a vegetated area. Riverton Creek is a relatively high quality stream and is known salmon habitat. The western portion of the west parcel appears to have a wetland area that is part of a wetland that is in SR 99 right-of-way. No other known wetlands are on the site. Construction Impacts: Like the Group Health Property Alternative, future work at the site will likely include improvements that accommodate Metro operational and administrative functions; however, the exact nature and type of those improvements is not yet known. Tenant improvement or other construction at the site to accommodate Metro's use would likely affect access by adjacent properties during construction. Construction vehicles would increase local traffic on East Marginal Way S which may cause slight delays to vehicles in the project vicinity. Cumulative and Indirect Impacts: Metro use of the site would result in relocating businesses which will affect other properties surrounding new business locations. Property Acquisition/Relocations: The property is not for sale and condemnation is possible if not likely. Condemnation could take a significant amount of time and could be controversial. Relocation of existing businesses would occur as a result of the project. Relocation could be controversial. Energy: Metro's use of the site is unlikely to increase energy use at the site, although this has not been quantified because exact uses have not been identified. Metro selects highly energy -efficient equipment and it is possible that energy use at the site would go down after Metro improves and occupies the property. Base Capacity Needs Planning —September 22, 2016 page 7 67 Attachment E Public Involvement: Metro has not conducted outreach related, specifically, to the acquisition of these properties, but has made extensive efforts with regard to Metro's Long Range Plan, which this acquisition would help to implement. Mitigation Measures: The exact nature and type of future improvements by Metro is not yet known, but any changes to the site by Metro would need local City of Tukwila review and approval which may include mitigation measures in addition to measure employed by Metro. During permit review for future improvements, the city of Tukwila could impose more restrictive buffers than currently exist related to Riverton Creek and also to the wetland area in the western portion of the site. Local regulations related to development near water features have become more restrictive in jurisdictions throughout King County. Construction phase mitigation measures would include best management practices to protect surface water, groundwater, and other resources. Operations measures would be included during design to ensure potential impacts are minimized. Permitting/Local Review: The exact nature and type of improvements by Metro is not yet known, but changes to the site by Metro would likely need local City of Tukwila review. Zoning is consistent with likely proposed uses of the site. During permit review for future improvements, the city of Tukwila could impose more restrictive buffers than currently exist related to Riverton Creek and also to the wetland area in the western portion of the site, since regulations related to development near water features have become more restrictive since the time the site was originally developed. Summary and Conclusion The No Action Alternative would constrain Metro's ability to expand base capacity at South Base and other bases in Metro's system. Metro must expand base capacity in order to improve the declining level of service at its bases. Expansion at South Base is a key element of that. The No Action Alternative is not a preferred alternative. The Group Health Property Alternative does not have any environmental features or aspects that affect use or development by Metro and would not present any significant adverse environmental impacts. The site is adjacent to the main South Base facility and has a large parking garage which would be used for employee parking. The office and warehouse areas are sufficient to meet Metro's space and functional needs for base expansion, and the site is ideal for relocating South Base operations, a key criterion. The site presents few challenges with acquisition and use by Metro. It would not involve condemnation, would not involve relocations, and is unlikely to produce any controversy. The site has a history of USTs and groundwater monitoring wells on site, but according to Phase I environmental site assessments, this would not present any impacts or limitations for use of the site. The Intergate East Properties Alternative presents several issues affecting Metro use of the site and results in potentially significant impacts related to acquisition, relocation, access and safety. The property is not adjacent to the main South Base facility and would be less efficient, functionally, than the Group Health Property Alternative and it is likely too far to relocate South Base operations; warehouse space is insufficient. The property is not for sale and condemnation appears to be likely. Condemnation can take a significant amount of time and can be controversial and time-consuming. The Intergate East Properties Alternative would likely require relocating existing businesses which could prove to be controversial and time-consuming. A signal may need to be installed at the intersection of South 120th Place and East Marginal Way South in order to improve safety, particularly for Metro employees crossing East Marginal Way South to access the main South Base facility. The No Action Alternative will not meet Metro's need for interim or long-term base expansion needs. Base Capacity Needs Planning —September 22, 2016 page 8 68 Attachment E In conclusion, the Intergate East Properties Alternative is not a preferred alternative as an interim or long-term solution to Metro base expansion needs due to issues related to acquisition, relocation, access and safety, and location relative to South Base. However, the site may have future potential due to its size, zoning and existing structures, and it may become a more viable option at a future date for long-term expansion needs. Metro's preferred alternative for current base expansion purposes is the Group Health Property Alternative because it has no significant issues related to acquisition or use by Metro, and it is ideally located for Metro's base expansion purposes. Base Capacity Needs Planning —September 22, 2016 page 9 69 70 DETE ' INATION OF NONSIGNIFICANCE (DNS) South Interim Bus Base — Phase 2: Site Development PROJECT DESCRIPTION: On November 16, 2018, King County's Metro Transit Division issued a determination of nonsignificance for the South Interim Bus - Phase 2: Site Development. Phase 2 of the South Interim Bus Base Project involves construction of the interim base, including paving to accommodate parking for up to 126 coaches, a bus maintenance building and installation of modular, portable structures for office and other base uses. Construction of Phase 2 of the project is expected to start during February 2019 and be complete by January 2020.

The City has the following comments regarding the project: 1. SEPA Checklist: Section 2 (a) Air — No estimate is provided of anticipated increase in emissions locally from the addition of 126 buses and employee parking. 2. SEPA Checklist: Section 2 (c) Air — Measures are provided for reducing or controlling emissions during construction by contractors. However, no best practices are provided for reducing emissions onsite during operations. This may include limiting idling time of parked buses, staging vehicle start times, etc. The City of Tukwila would like to be provided with additional information regarding King County Metro's strategy for reducing emission impacts from its operations in the immediate, short, and long term. 3. We ask that King County delay issuing a SEPA threshold determination until items 1 and 2 above are addressed and resolved. 4. SEPA Checklist: Section 4 (b & d) Plants — Project is subject to Tukwila Municipal Code Chapter 18.52: Landscaping Requirements. Modifications to existing landscaping and installation of any new landscaping will be required to meet the standards set forth for projects within the Manufacturing Industrial Center/Light district. 5. Cumulative traffic impacts from the the proposed South Annex Base expansion project were not addressed as part of this SEPA review. King County Metro will need to clarify if future traffic impacts for all base expansion projects will be addressed through the current Interim Base project or as part of a future SEPA analysis for the South Annex Base project. Thank you for the opportunity to comment. We look forward to King County providing the additional information we requested.

We hope you find the enclosed information valuable and that it adequately addresses the comments provided in your letter dated December 4, 2018. Regarding Comment 1, while the addition of up to 126 buses plus additional employee and non - revenue vehicles will increase emissions locally, the increase in emissions is not anticipated to raise to a level of significant impact. Although the new facility will have a capacity of 126 buses, Metro's programmed utilization for the site is limited to approximately 90 buses. This number won't occur upon initial activation of the South Interim Base. Initial base utilization likely will be approximately 40 buses and the numbers will phase up over time as Metro advances its fleet acquisition plan. The South Interim Base assigned fleet will be the newest diesel electric hybrid buses in Metro's fleet. These buses will be the best performing from the standpoint of fuel use and emissions. Additionally, Metro is electrifying its fleet with initial deployment of zero emission long range battery electric buses being planned for the South Base Campus starting as early as 2021. Regarding Comment 2, it is Metro policy as directed in King County Metro's 'The Book 2018 Operator Rules and Procedures' that, with few exceptions, operators are required to turn off coach (bus) engines immediately upon arrival at a terminal such as South Interim Base and all other layover points. Additionally and as is outlined above, Metro plans to deploy its newest diesel electric hybrid buses at South Interim Base which should address potential immediate and short term air quality impacts. 74 Attachment F Potential long term air quality impacts will be addressed by Metro's eventual deployment of an all - electric fleet. Regarding Comment 3, Metro issued the SEPA threshold determination for the subject project on November 19, 2018. Hopefully, the responses to Comments 1 & 2 above address your concerns. Regarding Comment 4, Metro plans to comply with all landscaping requirements for the Manufacturing Industrial Center/Light district. Regarding Comment 5, planning for the South Annex Base is not at a level of development that would allow analysis of comprehensive traffic impacts at this time. The subject SEPA checklist and DNS are specific only to development of the South Interim Base. Traffic impacts from the proposed South Annex Base will be addressed under a separate, stand-alone SEPA analysis once plans have reached a sufficient level of development. I hope this addresses your comments and concerns relative to the Metro South Interim Base SEPA Checklist and Determination of Non -significance. Please feel free to contact me directly at (206) 263-0506 or jgreene@kingcounty.gov with any additional questions or concerns you may have. Thank you for your valuable feedback and engagement.

Review Process 2. Background Information — Site and Project 3. Proposal Review • Staff Recommendations Project Proposal King County Metro Transit is proposing to redevelop the former Group Health office park, which is adjacent to their existing South Bus Base campus, for a new interim bus base. The proposed facility will be used for Metro Transit bus parking, operations and maintenance. The site is proposed to remain in use as an interim bus base for approximately five years. The proposed Interim office structures include modular buildings. The majority of the site will be graded flat, paved and striped for coach parking. Metro expects the facility to have a capacity of up to 126 coaches. The existing three story parking garage will be retained and used for employee parking. co Review Process — Unclassified Use Criteria 1. Where appropriate and feasible, all facilities shall be undergrounded. 2. Not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity. 3. Meet or exceed the standards for parking, landscaping, yards and other development regulations 4. Compatible generally with the surrounding land uses. 5. Consistent with the City's Comprehensive Plan. 6. Mitigate all significant adverse environmental impacts on public and private properties. Full consideration shall be given to: • (a) alternative locations and/or routes that reduce or eliminate adverse impacts; and • (b) alternative designs that reduce or eliminate adverse impacts. co Existing Site Conditions Existing Development Former Group Health office park which included a combination of office, manufacturing, and warehouse uses. No uses currently exist onsite. Surrounding Land Use North and west of the site- zoned MIC/L or MIC/H with manufacturing, warehouse, and office uses; SR 599 runs along the eastern boundary of the property; South of the site -zoned Low Density Residential (LDR) district; roughly half a dozen homes are located on these LDR properties at the top of a wooded hill and are located no closer than 500'tothe development area. Existing Site Conditions Vegetation Wooded hillside to the south and perimeter and parking lot landscaping associated with the former Group Health office park. As part of the development proposal, the majority of the site (not including the hillside) is to be reconfigured resulting in the removal of most of the existing formal landscaping. KC Metro has proposed replacing any trees removed as part of the new development. Access Existing access to the site is from E Marginal Way S in the form of two vehicle access points. These existing access points are proposed to be used for buses -only, with a third proposed access point to be used for employee -vehicle access to the parking garage. f \ thg asin EX STING 50„TH 5ASE LANDSCAPE.

Findings include: • South Interim Base is projected to generate —159 fewer total AM peak hour trips and 175 fewer total PM peak hour trips than the Group Health Facility. • All study intersections meet the City of Tukwila's operating standards for all future scenarios. • Proposed sites includes adequate space for bus traffic throughout the bus parking area and adequate space for personal and non -revenue vehicles to/from the employee parking garage. City of Tukwila Public Works Dept. concurs with TIR findings. mmammammannueueueueueueueueueueueueueuettettettut _JO _rt _Jr _66- _1_1_1 _6- 14 -44444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444, Public Outreach Notice of Application posted on the site and mailed to property owners and tenants within 500 feet of the project site. An informational public open house was held at the King County Metro South Training building. Notice of Public Hearing was posted on the site and mailed to the property owners within 500 feet and published in the Seattle Times. One comment was received at the public meeting on November 28, 2018. Marc Anderson, a King County Metro employee voiced support for the project, citing the importance of mass transit support in the South King County region. No other comments were received. co Conclusions • The project has been designed to mitigate potential impacts to surrounding properties and improvements in the vicinity related to noise, lighting, and aesthetics. • The project meets or exceeds the development standards within the Manufacturing Industrial Center - Light district. • The proposed development is compatible with surrounding land uses. Proposed setback and building heights are similar in scale to nearby structures, and landscaping along the perimeter of the project property enhances the site and provides a buffer for single-family homes to the south. • The proposed development is consistent with the Comprehensive Land Use Plan, including goals and policies within the Natural Environment, Residential Neighborhoods and Land Use, and Manufacturing/Industrial Center elements. • King County Metro considered several alternative project sites in vicinity of the South Base. Other sites were ultimately deemed too costly and/or would have had negative impacts on existing businesses/tenants. • The completed project will result in a secure facility, designed to blend in with the surrounding neighborhood and screened from adjacent properties by landscaping on all sides.
