Introduction 1.1 Overview Sound Transit is a regional transit authority that operates under Chapters 81.104 and 81.112 of the Revised Code of Washington (RCW) for the Pierce, King, and Snohomish Counties region. Sound Transit is authorized to construct and operate a high-capacity transportation system. In 2016, the voters approved the Sound Transit 3 Plan (ST3) to connect 16 cities with light rail, 30 cities with Stride Bus Rapid Transit (BRT) and Sound Transit Express bus service, and 12 cities with commuter rail. The high-capacity transit constructed by Sound Transit, including this proposal for a BRT transit center in the City of Renton (City), is an essential public facility as identified in RCW 36.70A.200 and Washington Administrative Code (WAC) 365-196-550. Sound Transit is proposing the Stride BRT system, which will include BRT service within the I-405 corridor for 37 miles between Lynnwood and Burien (Figure 1-1). As part of the BRT system, Sound Transit is proposing the construction of the South Renton Transit Center (SRTC). The SRTC will include a transit center with stops for Sound Transit and King County Metro (KCM) routes and with layover for KCM; bus operator facilities; a surface parking lot for transit center users; bicycle racks and lockers; and non-motorized access from Rainier Avenue S, S Grady Way, and Lake Avenue S. Additional work included in this project includes roadway improvements on Rainier Avenue S, S Grady Way, and Lake Avenue S to facilitate bus and pedestrian ingress and egress to the site; landscaping on the site; utility connections; and construction of a stormwater conveyance and treatment system. At the request of City staff, a Master Plan Review and Lot Line Adjustment (LLA) were submitted to the City to identify where a parking garage or transit-oriented development (TOD) site could theoretically be located. Currently, Sound Transit staff does not have the authority to apply for a parking garage entitlement or to surplus land for TOD. Sound Transit, as its own lead agency completed environmental review and issued a State Environmental Policy Act (SEPA) Determination of Non-Significance on September 30, 2020. This narrative has been prepared to accompany a Minor Modification of a previously approved Site Plan due to project design changes. A Site Plan Review was approved by the Hearing Examiner, along with a Conditional Use Permit (CUP), Master Plan Review, and LLA, on October 29, 2024 (City file no. PR21-000095). Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45 1-2 Figure 1-1. I-405 BRT Project Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45 2-1 2. Project Description The project is described in the following subsections. 2.1 SRTC Site Facilities and Circulation The SRTC will be located on an 8.3-acre site, comprised of four existing parcels, on the north side of I-405 and in the northeast corner of the intersection of S Grady Way and Rainier Avenue S (State Route [SR] 167) (Figure 2-1). Off-site improvements are proposed on a WSDOT-owned parcel to the North that includes Lake Avenue S and within the ROW of S Grady Way, Rainier Avenue, and Hardie Avenue SW. Four existing parcel boundaries making up the SRTC will be modified via the aforementioned LLA to plan for the potential future parking garage and TOD sites in the location of the proposed SRTC surface parking. Figure 2-1. Site Layout Facilities at the SRTC will include the following: Two new transit center islands and a bus loop area along the northern portion of the site, extending from Rainier Avenue S on the west side to Lake Avenue S on the east side with 9-inch curbs. The smaller transit center island near Rainier Avenue S will be approximately 166 feet long and will have one bus bay (Bus Bay 1). The larger transit center island, just east of the smaller transit center island, will have seven 61-foot-long active bus bays (Bus Bays 2 through 8), for a total of eight active bus bays on the site. I-405 BRT buses will use Bus Bay 1 on the smaller island and Bus Bay Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45 2-2 8, the southwest bay on the larger island. The remaining six active bays will provide space for other bus transit service operated by KCM. – At Bus Bay 1, the I-405 BRT station will include a transit shelter canopy. On the larger transit island, two shelter canopies will be provided for a length of approximately 60 feet and 180 feet, covering the majority of Bus Bays 2, 3, 6, 7, and 8. The top of each shelter will be between 12 and 15 feet in height. The tallest structure of the bus shelters will be approximately 23 feet tall. Shelters will be approximately 23 feet high. Seattle City Light (SCL) transmission lines along the eastern side of the SRTC site preclude the ability to extend canopies over Bus Bays 4 and 5. Instead of a canopy, a smaller 17-foot by 6-foot shelter, approximately 7.5 feet in height, will be located at Bus Bay 4. – At both Bus Bay 1 and 8, the I- 405 BRT station elements will also include a Stride-branded pylon along with ticket vending machines and validators, security cameras, public address speakers, and real-time bus information signs (variable message signs). Typically, each pylon structure will include a variable message sign screen for real-time bus information and will be internally illuminated to be identifiable in the evening and during hours of less light. South of the transit center islands and bus loop area, 13 bus layover spaces will be provided in the center of the site for KCM buses. The southwest corner of the site will be a 158-stall surface parking lot for transit center users. South of the transit center islands between the layover spaces and the parking lot will be the core facility building for storage, telecommunications and electrical equipment, and operator comfort stations. A decorative fence will be provided to delineate publicly accessible areas and the core facility building used by Sound Transit and KCM staff. A security building will be located to the north of the core facility building. The core facility building will be an L-shaped building measuring 113 feet long on its longest side, 51 feet long on the shorter side, and 16 feet wide. The security building will be 18 feet by 23 feet. Pedestrian access to the transit center site will be from the existing and reconstructed sidewalks along Rainier Avenue S and S Grady Way. The existing sidewalk on S Grady Way will be converted into a shared-use path. A new sidewalk will be constructed along the frontage of Lake Avenue S on the eastern side of the transit center. Pedestrian walkways will also be constructed within the transit center site from Rainier Avenue S, Lake Avenue S, S Grady Way, and along the east and north sides of the parking lot, which will include access to the proposed buildings. A second shared-use path will be constructed along the north property line. A cycle track will be constructed along Lake Avenue S to connect this new shared-use path with an existing cycle track on Shattuck Avenue S. Crosswalks will be provided between the sidewalks and walkways to the transit center islands. Luminaires will provide lighting throughout the site with 15- or 25-foot mounting heights. Luminaires to be provided within public right-of-way at 16.5- or 35.5-foot mounting heights per City standards. 2.2 Roadway/Pedestrian Improvements To access the SRTC, I-405 BRT buses heading southbound on I-405 will use the exit onto Rainier Avenue S into an existing northbound, curbside business access and transit (BAT) lane. I-405 BRT buses will stay in the existing BAT lane across S Grady Way along Rainier Avenue S. I-405 BRT vehicles heading northbound on I-405 will access the SRTC using the existing exit onto Rainier Avenue S. To improve transit speed and reliability, northbound I-405 BRT vehicles will use a new short section of a 14-foot-wide bus-only lane on northbound Rainier Avenue S that will start at the existing southbound I-405 loop ramp and extend north approximately 200 feet to connect with the existing BAT lane. For this bus-only lane, the existing paved shoulder will be replaced with a full-depth pavement, including a short section of the adjacent I-405 on-ramp and off-ramp. The bus-only lane will be striped and painted for bus use only and existing conflicting pavement markings will be removed. Adjacent to the north end of the bus-only lane, an existing light standard and its foundation will be removed, and a new light standard and pole will be installed. Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45 2-3 Once across S Grady Way, I-405 BRT buses heading northbound will turn right into the transit center’s bus loop at a new signalized intersection of Rainier Avenue S and Hardie Avenue SW. This new intersection will also be the primary ingress and egress for all BRT buses using the transit center and most of the KCM buses. Within this intersection, the existing raised, landscaped median on Rainier Avenue S will be removed to allow for turning movements, and crosswalks will be provided at each of the four roadway crossings. North of this intersection, the existing center median within Rainier Avenue S will be removed for a new southbound bus-only left-turn pocket for KCM buses turning left into the transit center; a small section of a center median may remain at the southern end of the bus-only left-turn pocket. At the connection to Rainier Avenue S, Hardie Avenue SW will be reconstructed to realign the southbound lane adjacent to the northbound lane. This shift will require removing the northern portion of an existing raised, landscaped island. In place of the existing southbound lane on Hardie Avenue SW, a landscaped curb return will be constructed that will connect with the remaining portion of the existing island. For general-purpose traffic, the southbound lane on Hardie Avenue SW will be right-turn only. A secondary bus access into the transit center’s bus loop will be provided from Lake Avenue S on the east side of the site. This secondary access will also provide connectivity to the bus bays and layover spaces at the existing South Renton Park-and-Ride just east of the SRTC. Access from Lake Avenue S provides bus circulation and access from S Grady Way, Shattuck Avenue S, and S 7th Street. I-405 BRT buses leaving the SRTC will turn left onto Rainier Avenue S into an existing, southbound curbside BAT lane and then onto either northbound or southbound I-405 using existing on-ramps. Signal-timing improvements will be made, including adding transit signal priority to the traffic signal at the intersection of S Grady Way and southbound Rainier Avenue S. In addition to the previously described changes to roadways, intersections, and access to the SRTC site, the project includes frontage improvements along the site’s entire length on S Grady Way and Lake Avenue S and in the northern portion of Rainier Avenue S. Within the right-of-way for S Grady Way, the frontage improvements include demolishing the existing sidewalk, adding a landscape strip at the back of the curb, and installing a cement concrete shared-use path at the back of the landscaping as part of a dedication to the City. This shared-use path and landscaping strip will continue north along Lake Avenue S, with an improved accessible curb ramp at the corner, up to the driveway to the parking lot. Additional landscaping will be provided to separate the walkways along S Grady Way and Lake Avenue S from the rest of the transit center. North of the bus loop driveways along Lake Avenue S, additional sidewalk and landscaping frontage improvements are proposed, which will be supported by a new retaining wall. A fence will be placed on top of the wall to delineate the boundary between the public space at the transit center and the car dealership to the north. This proposed wall and fence is the subject of this variance request, which is discussed further in Section 4. Along Rainier Avenue S, beginning just south of the driveway into the parking lot, similar frontage improvements of a landscape strip behind the curb will be constructed. Refer to Section 2.3 for additional information on proposed landscaping. To increase the City’s connectivity of bicycle-friendly infrastructure, a cycle track will be constructed on the east-west portion of Lake Avenue S. This cycle track will provide protected bike lanes to connect the proposed shared-use path on the north property boundary, and the SRTC as a whole, to the existing cycle track on Shattuck Avenue S. For construction of the bus-only lane along Rainier Avenue S, the contractor may stage equipment and materials in the area to the east of Rainier Avenue S, within the existing, unpaved right-of-way for I-405. For construction of the SRTC, the contractor will stage the necessary equipment and materials on the site. 2.3 Landscaping Within the project site, areas that are not required for the transit center facilities or site circulation or that do not have limitations because of the utility easements will be landscaped. Along the northern site boundary, a landscape strip ranging between approximately 5 feet and 10 feet wide will be provided between the transit center and the proposed shared-use path. It will consist of a mix of low-growing shrubs and deciduous/accent trees. The traffic median separating the layover drive aisle from Lake Avenue S and the Lake Avenue S parking lot entrance will be landscaped as well. The wider part of the median that includes the sidewalk on Lake Avenue S will be landscaped with a lawn and minimum 7-foot side strips of shrubs and ground cover. As the median thins and heads southwest to separate the parking lot entrance and Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45 2-4 bus layover drive aisle, shrubs and deciduous trees will be added at a width of approximately 10 feet. Similar to the landscaping along the north edge of the site, perimeter landscaping, consisting of a mix of low-growing shrubs and deciduous/accent trees, will be installed along Rainier Avenue S and in the modified curb return of Hardie Avenue SW. At the corner of Rainier Avenue S and S Grady Way, a larger planted area will be located behind the existing sculpture and low concrete wall, which will remain; this landscaped area will also include some conifer trees, deciduous trees, and shrubs. Along S Grady Way, the perimeter landscaping will include the same spacing of deciduous/accent trees within alternating sections of grass lawn and low-growing shrubs. The area between the shared-use path along S Grady Way and the rest of transit center (parking lot, core facility building, equipment yard, and Lake Avenue S parking lot entrance) will be extensively landscaped to soften the view of the transit center to pedestrians and motorists along S Grady Way. The centerpiece of this landscaping area will be three meandering, vegetated bioretention facilities compliant with the Washington State Department of Ecology (Ecology) Stormwater Management Manual for Western Washington (SWMMWW). Two plaza pathways will cut between the bioretention facilities to provide pedestrian access from S Grady Way to the parking lot. Vegetation between plaza pathways, bioretention facilities, structures, and other decorative features will be a combination of deciduous and conifers trees, a variety of shrubs, and ground cover in both the form of grass and groundcover shrubs. Decorative features will include lighting, seat walls, and decorative plaza pathways adjacent to the shared-use path. 2.4 Site Utilities In the southern portion of the site (adjacent to S Grady Way) there is an existing Puget Sound Energy (PSE) power line easement. In the eastern portion of the site (adjacent to Lake Avenue S) there is an existing SCL power line easement. Along the south boundary, the easement is approximately 100 feet wide. In the eastern portion of the site the easement is approximately 200 feet wide. Prior to the start of construction, Sound Transit will coordinate with SCL, and utility providers as needed, to ensure construction activities will not interfere with their facilities and service. Once constructed, the transit center facilities will not alter, affect, or interfere with the existing 240 kilovolt transmission lines across the site. The easement area under the transmission lines will primarily be green space (where existing pavement will be removed) and ground-level improvements. The project will require water, sewer, electrical, and fiber service to the proposed buildings. A minimum of two fire hydrants will need to be installed on site. Fiber and electrical service will also be required at the transit center islands, and electrical service will be required for site lighting. The City has existing water and sewer mains in Rainier Avenue S to serve the site. Electrical and fiber optic lines are also located in Rainier Avenue S. Since the project site consisted of a previous auto sales and service use, there are existing water, sewer, and power lines that extend onto the site. These existing lines will have to be removed, and new extensions will have to be constructed to serve the transit center facilities in their proposed locations. The City also has a water main in an easement across the site. This water main will have to be relocated, and the easement vacated as part of construction. 2.5 Storm Drainage Runoff from the project site is currently collected and conveyed to a storm system within Rainier Avenue S. This system crosses Rainier Avenue S north of S Grady Way and conveys flow to Springbrook Creek. Stormwater management at the transit center site will comply with the City’s Surface Water Design Manual and Ecology’s SWMMWW. For the bus-only lane within the Washington State Department of Transportation’s (WSDOT’s) limited access right-of-way for I-405, WSDOT’s Highway Runoff Manual will apply. On the transit center site and along Lake Avenue S, the project will construct a system of stormwater collection pipes and catch basins to collect stormwater and convey it to the detention system onsite, north of S Grady Way and west of the driveway from S Grady Way. Along the site’s frontage along S Grady Way, a ditch will be constructed that will convey stormwater to the same detention system. The detention system will include vegetated bioretention facilities that will Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45 2-5 detain and filter the stormwater before conveying it offsite to the City’s existing piped storm drainage and conveyance systems. At the new intersection of Rainier Avenue S and Hardie Avenue SW, new segments of stormwater collection pipes and catch basins will be constructed, connecting to the existing storm drainage system in Rainier Avenue S. 2.6 Excavation and Backfill To construct the SRTC, approximately 12,906 cubic yards of soil will be removed, and 14,150 cubic yards of fill will be used as back fill. The source of fill will be determined by the contractor. 2.7 Public Artwork Public art is proposed at the bus canopies and in the surface parking lot. The bus canopies will consist of art glass that also function as clerestory window elements. In partnership with King County 4Culture, the surface parking lot will consist of artwork specific to surface parking lot and translated in a durable and slip-resistant material for application onto the pavement. The STart program will lead community engagement as the specific artwork design is developed, which will include consultation with the Renton Municipal Arts Commission for both the canopy and surface parking lot artwork and approval from the 4Cculture Public Art Advisory Committee for the surface parking lot artwork. Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45 3-1 3. Site Description 3.1 Zoning Designation and Current Site Use The SRTC project site, located at 750 Rainier Avenue S, is in a highly developed commercial area (northeast of the intersection of Rainier Avenue S [SR 167] and S Grady Way). Refer to the Neighborhood Detail Map on Figure 3-1. The SRTC site, and the surrounding area, is zoned Commercial Arterial (CA). Refer to Figure 3-2 for site and surrounding zoning designations. The City’s Comprehensive Plan designates the area as “Commercial Mixed Use.” The SRTC site is within the Urban Design District D and Airport Related Height and Use Restrictions Overlay Districts. Urban Design District D Overlay requirements were discussed as part of the land use submittal to the City. Sound Transit owns the four parcels that comprise the site (King County parcel numbers 192305- 9035, 9063, 9068, 9074); the businesses that were previously on the site have been relocated. In September 2021, the City approved a demolition permit, a critical areas exemption (for work within a Seismic Hazard Area), and a critical areas approval (for work within a Wellhead Protection Area) for the demolition and removal of the four buildings that were onsite. Demolition of these four buildings was completed on January 14, 2022, with the building foundations remaining. The roadway improvements along Rainier Avenue S (north of S Grady Way) and Hardie Avenue SW are proposed within the City’s public right-of-way. Roadway improvements along Rainier Avenue S, south of S Grady Way, and Lake Avenue S are within WSDOT right-of-way or limited access right-of-way for I-405 and are not subject to the City’s jurisdiction.

City Zoning Designations in the Project Area 3.2 Soil Type and Drainage Conditions The soils on the site are alluvium consisting of sand and gravel deposited by the Cedar River. Subsurface testing at the SRTC site found loose fill soils over alluvial soils primarily comprised of soft silts and loose sands. Recent geotechnical borings conducted at the site indicate that liquefiable soils are present; denser soils were encountered below soils that are subject to liquefaction. This site is in the Green River subwatershed within Water Resource Inventory Area (WRIA) 9: Duwamish – Green. Runoff from the site is currently collected and conveyed to a storm system within Rainier Avenue S. This system crosses Rainier Avenue S north of S Grady Way and conveys flow to Springbrook Creek. Runoff from S Grady Way is collected and conveyed south to Rolling Hills Creek through privately owned parcels south of S Grady Way. Rainier Avenue S has two drainage basins. North of S Grady Way, runoff from Rainier Avenue S is directed to Springbrook Creek and south of S Grady Way runoff is directed to Rolling Hills Creek. 3.3 Critical Areas The entire SRTC site and surrounding roadways are in a Seismic Hazard Area, as designated and mapped by the City (Figure 3-3). The entire site is also located in a Wellhead Protection Area Zone 2 critical area (Figure 3-4). Therefore, all the proposed project improvements are located within these critical areas. The area south of S Grady Way is also mapped Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45 3-4 within a Special Flood Hazard Area and Other Flood Area (Figure 3-5). Figure 3-5 also shows areas within the vicinity that are mapped by the City as steep slopes, which are primarily small sections of graded slopes adjacent to I-405. Within the area mapped as a Special Flood Hazard Area and Other Flood Area, the only associated project improvement is the bus- only lane within WSDOT’s limited access right-of-way. No other critical areas or associated buffers are located in this area. Before any development or alteration of a property containing a critical area, RMC 4-3-050(C)(1) notes that the owner or designee must obtain a development permit, critical area approval, and/or letter of exemption. Therefore, a Critical Areas Report was prepared and submitted to the City. Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45 3-5 Figure 3-3.

Minor Modification of Previously Approved Site Plan As stated previously, the SRTC Site Plan was approved in conjunction with the CUP, Master Plan Review, Site Plan Review, and LLA on October 29, 2024. Since this approval, KCM has adjusted the scope of their BEB program so the proposed charging gantry and BEB equipment yard are no longer necessary. Sound Transit has modified the design of the site to remove the charging gantry, the BEB equipment yard, and hammerhead to the east of the BEB equipment yard that was to be used for service vehicles (Figure 2-1). The bus layover area will remain, just without the BEB charging gantry. Landscaping will replace the hammerhead and BEB equipment yard location. The proposed design changes will not impact the SRTC’s overall compliance with applicable RMC and conditions pursuant to the CUP decision. Docusign Envelope ID: 4CF7BBEF-EE1C-4797-8BE8-93BC391B0A45
