We work across disciplines that match the complexity of cities to address sustainability challenges, from regional planning to building design and from enhancing engagement of diverse communities to understanding the impacts on municipal budgets from disruptive technologies and many issues in between. SCI focuses on sustainability-based research and teaching opportunities through two primary efforts: 1. Our Sustainable City Year Program (SCYP), a massively scaled university- community partnership program that matches the resources of the University with one Oregon community each year to help advance that community’s sustainability goals; and The Sustainable City Year Program (SCYP) is a yearlong partnership between SCI and a partner in Oregon, in which students and faculty in courses from across the university collaborate with a public entity on sustainability and livability projects. SCYP faculty and students work in collaboration with staff from the partner agency through a variety of studio projects and service- learning courses to provide students with real-world projects to investigate. Students bring energy, enthusiasm, and innovative approaches 2. Our Urbanism Next Center, which focuses on how autonomous vehicles, e-commerce, and the sharing economy will impact the form and function of cities. In all cases, we share our expertise and experiences with scholars, policymakers, community leaders, and project partners. We further extend our impact via an annual Expert-in-Residence Program, SCI China visiting scholars program, study abroad course on redesigning cities for people on bicycle, and through our co-leadership of the Educational Partnerships for Innovation in Communities Network (EPIC-N), which is transferring SCYP to universities and communities across the globe. Our work connects student passion, faculty experience, and community needs to produce innovative, tangible solutions for the creation of a sustainable society. to difficult, persistent problems. SCYP’s primary value derives from collaborations that result in on-the-ground impact and expanded conversations for a community ready to transition to a more sustainable and livable future. Community partnerships are possible in part due to support from U.S. Senators Ron Wyden and Jeff Merkley, as well as former Congressman Peter DeFazio, who secured federal funding for SCYP through Congressionally Directed Spending. 4 Fall 2025 Pathways to Progress: Transportation Planning for People, Parking, and Public Spaces in Downtown Tualatin About SCI About SCYP The city’s history dates back to the mid- 1800s and is rooted in entrepreneurship and transportation.

Downtown Tualatin currently functions as an auto-oriented corridor shaped by major arterials, commuter-through traffic, and physical barriers such as Interstate 5 (I-5) and rail crossings. Key existing conditions include: • Major arterials (SW Boones Ferry Road, SW Tualatin-Sherwood Road, SW Nyberg Street) that provide high vehicle volumes yet create hostile walking and biking conditions. • Gaps in comfortable, intuitive multimodal connections between destinations such as the WES station, downtown businesses, trails, and the Lake at the Commons. • Extensive, underutilized surface parking that limits downtown vibrancy and limits connectivity. The proposed recommendations emphasize building a cohesive downtown core while preserving regional connectivity on key corridors. The recommended projects include: • Rail grade separation at SW Boones Ferry Road & SW Tualatin-Sherwood Road: Reduce recurring congestion and reliability issues caused by rail crossings at high-volume intersections. • Boones Ferry Road Corridor Improvements: Clearer lane organization to improve connectivity to the WES station, trail system and downtown core using protected bike facilities, safer crossings and reduced conflict points. • Targeted Pedestrian Safety Interventions on SW Tualatin- Sherwood Road: Improve controlled crossings, through pedestrian hybrid beacons, traffic calming and speed management. • Downtown placemaking and pedestrianization: Shift priority from through-traffic to local access and community life, including a Martinazzi Pedestrian Plaza and a downtown pedestrian alley connection into the Lake at the Commons. • Parking and Consolidation and redevelopment: Develop a multi-level parking structure to free land for mixed-use, cultural, retail and social spaces, complemented by converting a gravel lot to a green space to improve aesthetics, placemaking and climate resilience. Put together, these projects offer recommendations to improve safety, multimodal connectivity, support placemaking and economic development, and shift Tualatin from car-dominant design toward a safer, more connected, and sustainable downtown. Executive Summary This report reflects a collaborative effort to evaluate transportation conditions and opportunities in and around the Lake at the Commons area of Downtown Tualatin, Oregon. The report focuses on three integrated focus areas: (1) Multimodal Transportation, (2) Network and (3) Parking & Land Use. 7 The City of Tualatin envisions “an efficient, accessible, innovative, sustainable, and connected transportation system that effectively and safely meets the needs of our entire community” (City of Tualatin, 2030 Vision). Guided by that vision, the City of Tualatin partnered with the University of Oregon’s Sustainable City Year Program (SCYP) to better understand the current challenges and identify key opportunities to support a more connected, livable, and sustainable downtown core. This report presents the work of student teams in PPPM 399: Urban Transportation, produced in collaboration with the City of Tualatin. Over the course of the term, students engaged in an applied transportation planning process that included field observations, mapping exercises, evaluations of existing conditions, and policy reviews. The class began with a site visit to downtown Tualatin in early October 2025. Each student documented observations related to safety, mobility, access, and land-use conditions through an individual memo. An in-class community engagement simulation then challenged students to identify broader themes, articulate community values, and consider the perspectives of multiple stakeholder groups. Students then prepared a second memo with insights from this simulated engagement process. Students were then assigned to one of three focus areas: (1) Multimodal Transportation, (2) Network or (3) Parking & Land Use, to conduct an existing condition and needs assessment. These assessments identified recurring challenges such as congestion, gaps in pedestrian and cycling infrastructure, barriers to transit access, and underutilized land and parking lots. Based on these assessments, each focus-area group developed an initial list of potential projects to improve the needs they identified. In the final phase of the course, students were grouped into three large multidisciplinary teams with members from all three focus areas. These teams refined their analyses, integrated multimodal and mixed-use considerations, and created cohesive presentations. Each team presented a final briefing with Tualatin staff, Community Advisory Council members, and the mayor. Introduction 8 Fall 2025 Pathways to Progress: Transportation Planning for People, Parking, and Public Spaces in Downtown Tualatin MULTIMODAL TRANSPORTATION Multimodal transportation refers to a system that supports multiple travel options, such as walking, biking, rolling, and transit, through infrastructure like sidewalks, bike lanes, and transit stops. The purpose of multimodal transportation is to provide safe, convenient alternatives to driving so users can access opportunities and resources regardless of car ownership. Multimodal transportation is an important consideration because it expands mobility choices, reduces dependency on single- occupancy vehicles, lowers greenhouse emissions, and supports active modes of travel (Litman, 2024). Including multimodal transportation ensures the transportation system is designed for all users and aligns with the City of Tualatin’s goals for sustainability, equity, and improved access (“Core Opportunity Reinvestment Area Plan”, 2022). NETWORK CONNECTIVITY Network connectivity refers to a system of roadways and transit routes that enable the movement of people and goods throughout an area. The network includes streets, intersections, highways, and transit corridors to support efficient and reliable travel. A well-functioning transportation network is important because it provides the foundation for local and regional mobility. Roadways support day-to-day travel and freight movement, while transit offers mobility for regional access and high-capacity travel in congested areas. Including network connectivity ensures the transportation system is designed to support safety, mobility, efficiency, and long-term growth. PARKING & LAND USE Land Use refers to how land is developed and used, including housing, commercial, industrial and public use, and how these spaces shape where people live, work, and travel. Parking refers to the supply, location, and use of parking spaces, including on-street parking, surface lots, and structured parking. Together, land use and parking strongly influence travel behavior, transportation demand, and the overall efficiency of the transportation system. Including land use and parking ensures the transportation system supports mobility, development patterns, and economic growth. Focus Areas 9 This report will focus on transportation surrounding the Lake at the Commons area of downtown Tualatin, Oregon. Key locations within the study area have been identified.

Key documents include the 2045 Transportation System Plan (TSP) (effective September 2025), the Core Opportunity Reinvestment Area Plan (CORA) (2022), and the Comprehensive Plan 2040. MULTIMODAL TRANSPORTATION Existing Conditions: Downtown Tualatin offers infrastructure for walking, biking, and rolling but connections among trails, Lake at the Commons, shopping centers, and transit infrastructure often lack safe infrastructure, intuitive connections, and protective separation from high-speed traffic. Bicycle infrastructure on fast arterials is largely unprotected (often paint- separated), and safety concerns have been reported in cyclist-involved collisions along Boones Ferry Road and SW Tualatin-Sherwood Road. Similarly, pedestrian safety improvements (e.g. installations of Rectangular Rapid Flashing Beacons) address some crossing issues, but do not fully resolve broader connectivity to key destinations for pedestrians. Transit hubs include the WES Commuter Rail (weekday peak-period service), the Tualatin Park & Ride (bus connections to Lines 76, 96, 97), and the Ride Connection Tualatin Shuttle for first/last-mile access. However, gaps remain in first/last mile Current Transportation Plans and Policies Existing Conditions & Needs by Focus Area Together, these documents establish a vision and goals for transportation including multimodal access, quality of life, and strategic reinvestment in underutilized space. The City of Tualatin envisions a safe, multimodal, accessible, and future-oriented transportation system that supports community, livability, economic development, and sustainable growth (City of Tualatin, 2025). connectivity between transit stops/hubs and the downtown core, particularly across large arterials and through areas with large surface parking. Needs: Close pedestrian gaps, add protected bike lanes on high-volume corridors, provide safer and more legible crossings, upgrade transit access and amenities near high- demand nodes inducing the WES, Park & Ride, and commercial zones. NETWORK CONNECTIVITY Existing Conditions: The downtown network is shaped by automobile-oriented design and the dominance of major regional corridors, including SW Tualatin-Sherwood Road, SW Boones Ferry Road, and SW Nyberg Street. Additionally, Interstate 5 (I-5) provides major access to the greater Portland Metropolitan area and neighboring states, reinforcing the City’s role in regional mobility. However, this auto-centered design combined with the presence of rail infrastructure and multiple at-grade crossings, creates reliability challenges 11 and recurring traffic flow disruptions. These conditions contribute to an environment that prioritizes vehicle throughput over local mobility, multimodal access, and comfortable downtown connectivity. The intersection of SW Tualatin-Sherwood Road and SW Boones Ferry Road is one of the busiest in Washington County and is further constrained by an adjacent at- grade rail crossing. Congestion near I-5 and along Nyberg Street and Martinazzi Avenue corridor also frequently restricts traffic flow, leading to spillback, turning conflicts, and traffic delays. Traffic volumes at the intersection of SW Boones Ferry Road and SW Tualatin- Sherwood Road are among the busiest in the county with 25,000 to 38,000 vehicles travelling per day in each direction between 2021 to 2025. When trains block the at-grade crossing, delays place further strain on existing congestion and significantly reduce network reliability. These recurring issues suggest that grade separation or operational redesign could improve Tualatin’s overall transportation system. Needs: Improve safety and reliability at key intersections like SW Tualatin-Sherwood Road and Boones Ferry Road. Maintain regional person throughput for freight and commuters and create predictable and comfortable crossings for non- drivers. Due to Tualatin’s geographical position, it serves as a throughway for commuters, bringing in high traffic volumes that often cause congestion. Tualatin would benefit from redesigning major arterial roads to incorporate safer mid-block crossings, protected bike lanes, and linkages to trail systems. PARKING & LAND USE Existing Conditions: The downtown district includes extensive surface parking that appears largely underutilized and poses barriers to a vibrant, walkable downtown core. In addition to reducing downtown activity, large parking spaces can create unsafe conditions for pedestrians due to car activity. These conditions present various opportunities to consolidate parking and redevelop freed land for active uses such as mixed-use retail, cultural districts, community gathering spaces, and green space. Additionally, the recent state policy updates of HB2001 eliminate parking minimums and opens pathways for parking consolidation and mixed-use design. Needs: Consolidate parking space into a structured facility to free up land for green space, public space, and/or retail. Ensure design adheres to updated code and advances walkable and mixed-use design. 12 Fall 2025 Pathways to Progress: Transportation Planning for People, Parking, and Public Spaces in Downtown Tualatin Project recommendations were assessed using a weighted, multi-criteria approach emphasizing (C1) Safety & Accessibility, (C2) multimodal connectivity, (C3) Efficiency, (C4) Sustainability & Placemaking, (C5) Feasibility & Strategic Fit. These criteria along with the City’s vision of creating a transportation system that is “efficient, accessible, innovative, sustainable, and connected in a way that effectively and safely meets the needs of the entire community.” Each project was then scored based on their alignment with each criterion. Scores reflect the project’s impact and prioritization and are a tool to guide further planning and phasing stages.

Intersection Redesign SW Nyberg Street and Martinazzi Avenue Shortens crossings, calms traffic operations and increases recreational accessibility 73 Combined Recommended Project List All three focus areas share priorities in connectivity, safety, placemaking, and sustainability. Projects that repurpose auto-centered spaces (e.g. parking redevelopment, plaza conversions) complement corridor and crossing improvements that make walking and biking accessible and safe. Additionally, network improvements that reduce delays and improve predictability can support downtown growth by providing local connectivity without compromising regional mobility. 28 Fall 2025 Pathways to Progress: Transportation Planning for People, Parking, and Public Spaces in Downtown Tualatin Conclusion The Lake at the Commons presents various opportunities for Tualatin to advance its vision of creating “an efficient, accessible, innovative, sustainable, and connected transportation system that effectively and safely meets the needs of [the] entire community” (City of Tualatin, 2030 Vision). While existing conditions reflect decades of auto- oriented development, characterized by high-volume arterials, rail conflicts, and large plots of underutilized parking, this report presents pathways for meaningful progress toward the City’s goals. Through a comprehensive assessment of multimodal transportation, network connectivity, and parking and land use, this report outlines a set of recommendations that collectively shift Downtown Tualatin toward a more walkable, accessible and vibrant core. The proposed projects prioritize safety, reinforce critical transit and trail connections, emphasize public spaces, and encourage development patterns that support community life and economic growth. Implementing these improvements, ranging from protected bike facilities and pedestrian plazas to strategic parking consolidation and grade separation of the City’s most constrained intersection, will help Tualatin transition from a pass- through corridor for commuters to a thriving destination centered around the Lake at the Commons. These investments will improve day-to-day mobility and reliability for all users and will also strengthen placemaking, climate resilience, and the overall livability of Downtown Tualatin. Together, these recommendations provide a roadmap for Tualatin to evolve into a sustainable, connected, and community-oriented downtown. PROJECT PURPOSE SCORE B4.
