Item Open Access 68th and Rock Creek Station(University of Oregon, 2018) Heese, Brianna; Ribe, RobThis studio project was organized around the plans for a new TriMet light rail line to Tigard, Tualatin, and Washington County. Though this Southwest Corridor project is still in the early phases of planning and design, the studio collaborated with TriMet planners and the City of Tigard to visualize the future of a site that is likely to become a major station area. In addition, the site is seen as a critical location for a Park and Ride structure as this point marks where traffic into Portland drastically increases. The merge from Pacific Highway (99W) onto Interstate 5 (I-5) lies one-half mile east of the site, and the intersection of the two sees daily congestion and long waiting traffic. This site provides opportunities beyond transit. Older development near the site has potential to be acquired by the project for use as Park & Ride, LRT station, and for potential development of parking and transportation-related uses. Other adjacent sites can be critical purchases for developers given the benefits of the transit station. The City of Tigard supports plans for these future developments that include sustainable transit-oriented design, and restoration of environmental assets, such as Red Rock Creek, as opposed to box commercial development that maintains an auto-oriented focus. Students were tasked with considering the area surrounding the future station site as well as places that may be developed in later phases. The class divided into groups of various sizes, each focusing on a different approach to the transit-oriented development (TOD) proposed around the new TriMet station. Most teams developed 80- and 40-scale designs to create a cohesive master plan across the site before taking a more individual approach on an area with a smaller extent and more detail. Groups included: • “Stormwater Impacts”, Chrissy Stillman This design focuses on Red Rock Creek as its own entity. Chrissy calculated on and off-site storm water entering the creek, its ephemeral flooding zones, and the impacts of more hardscape in the area. Much of her design strategies for reducing the “flashiness” of the creek occurred east of the study area toward I-5. • “68th and Rock Creek Parking Structure”, Kailee Bell This design focuses on the opportunity of an off-site parking structure west of SW 68th Parkway that could provide rooftop amenities and access to a multimodal path along the bridged rail line leading into the station. This alternative solution frees up space for transit-oriented development in the site south of the station by providing at least half the required parking within a reasonable off-site distance. • “Place over Parking”, Thomas Copper and Nick Sund This design focuses on the maximum integration of parking in a high-density transit-oriented development site adjacent to the light rail station. This team focused on TOD1, the second thing likely to be built by developers after the station. • “Positively Tigard” Adam DeHeer and Yumna Imtiaz This team focused on a design of the station and the transit-oriented development with an approach of impact mitigation and sustainability. This group focused on the station plaza and TOD1 and worked closely with Chrissy Stillman for assessing storm water impact of their design proposal. • “Tigard Terraces”, Brianna Heese, Emma Stone, Bocong Li, and Tori Murphy This team focused on the topography of the site to integrate a medium density transit-oriented development. The team proposed designs for the station plaza, TOD1, Red Rock Creek, and TOD2 to meet the long-term phasing goals of TriMet and Tigard. Students generally found the site challenging in terms of balancing programmatic requirements with creating livable and enjoyable spaces. The student designs offer the best attempts to combine the two goals and do so in many ways. The required amount of parking was a challenge, and most students found that the best way to create a functioning transit-oriented development was either to invest in a parking structure below development or to site the parking across SW 68th Parkway. Additionally, if Tigard and TriMet desire sustainable and ecological designs, many teams suggest partnering with developers now and planning for elements to be incorporated. Finally, Red Rock Creek presents a potential flood problem for nearby development. Teams recommend multiple ways to reduce the flashiness of the creek, such as capturing stormwater on site for any new development.Item Open Access Active Transportation Proposals for Portland Neighborhoods(University of Oregon, 2017) Rose, Mike; Abe, DerekUnder the guidance of instructors Mike Rose and Derek Abe, Portland State University students worked in small groups to create active transportation plans for two sites within TriMet’s Southwest Corridor project area. Barbur Boulevard/19th Street MAX Station Integration The proposed SW Barbur Boulevard/19th Street MAX Station will be located in Southwest Portland as part of the new Southwest Corridor MAX Line connecting Downtown Portland with Tigard and Tualatin. This project focused on three main goals for Tri-Met as they construct a new MAX Station at 19th and Barbur: safety prioritization for bicyclists and pedestrians, improved connectivity for all road users to the new station, and community involvement to help identify solutions for the first two goals. A variety of recommendations are proposed, with a focus on three levels: station level, regional connectivity, and intersection level. Baylor/Clinton Station Pedestrian + Bike Access Plan The Southwest Corridor Light Rail will connect Downtown Portland with Tualatin through the City of Tigard. In coordination with Tri-Met Southwest Corridor Light Rail project, students developed a bicycle and pedestrian station access plan for the proposed Baylor/Clinton MAX station on Southwest 70th Avenue in the Tigard Triangle. The team’s mission in developing this plan is to ensure that all of the existing and future residents, workers, shoppers, students, and other people within this station’s walkshed and bikeshed will be able to get to and from the station on foot and by bicycle along safe, attractive, and comfortable walkways and bikeways. In addition, this plan includes complete bicycle and pedestrian networks for the Tigard Triangle and connections to the bicycle and pedestrian network beyond. The proposed plan recommends near-term and long range phases. Design guides for various roadway types are included, as well as complete street design elements such as bike lane buffers, bus stops, crossing sidewalk extensions, mini-roundabout, Red Rock Creek Trail, street furniture, street lighting, street trees, and a wayfinding program. Eight specific policies and programs are proposed, as well as the cost implications.Item Open Access Destination: Tigard Transit-Oriented Development and Urban Design Strategies(University of Oregon, 2018) Hirzel, Hannah; Larco, NicoTigard, a suburb of Portland, Oregon, is interested in a new urban design vision as a new MAX light rail line is proposed to extend through the city. TriMet and the city of Tigard partnered with a University of Oregon graduate architecture seminar and design studio to envision a new plan and identity for the city. The city of Tigard sees this new transit line as an opportunity on many levels. Tigard aims to be the “most walkable city in the Pacific Northwest,” which could include a shift from its current identity as a transit line transfer point into a destination for visitors and commuters. With a new light rail line making travel to downtown Portland and surrounding suburbs easier, the city of Tigard sees opportunity for growth and development, and the potential to redefine some of its city goals. Student teams of three to four members tackled these issues and presented proposals for a new town center in Tigard. Though each team proposed unique schemes, there are similar issues and goals. Some key focus areas include: • Creating a public “place” and identity where the MAX light rail stops in Tigard • Creating a connection to the existing town • Celebrating Fanno Creek, a natural area and trail system located west of downtown • Re-designing Hall Boulevard to become safer and more accessible for pedestrians • Redefining the city grid and creating more manageable block sizes The following proposals have various approaches to urban design and the future vision for the city of Tigard, but all make an effort toward sustainable urban design. Through effective street design, stormwater management, pedestrian-focused public spaces, mixed-use development strategies, and more, these proposals aim to develop Tigard into a place where people want to live, develop, and enjoy public spaces.Item Open Access TriMet Southwest Barbur Boulevard Stormwater Capstone Project(University of Oregon, 2018) Garstecki, Bernadel; McLaughlin, PatrickThis project was designed by ALBA Consulting. ALBA Consulting is an academic exercise comprised of four members of an undergraduate capstone class in engineering at Portland State University during winter and spring terms, 2018. ALBA Consulting strives to be a steward of sustainable solutions by engineering effective future assets for the communities we serve. The group sorted itself into professional roles, including: a Project Manager, an Assistant Project Manager, a Scribe, and a Quality Control Technician. Furthermore, each member also had a technical role providing supplemental content generated in AutoCAD, GIS, and Excel. The following design report consists of preliminary facility designs and an alternative analysis for the TriMet Southwest Barbur Boulevard Stormwater Capstone Project. Over the course of six months, ALBA consulting prepared a construction cost estimates, a construction schedule, a drawing set, calculations, and site hydrographs in addition to other deliverables for this project. This capstone project was developed from the ongoing Southwest Corridor Light Rail Transit (SWC) Project, which is presently underway at TriMet. The purpose of the SWC Project is to connect downtown Portland, Tigard, and Tualatin with public transportation, thus providing a more convenient way for people to commute within the area while also reducing the number of personal vehicles on the roads. This project is currently in the preliminary design phase, and many aspects of the project have not been finalized, therefore, this report will focus on only one aspect of the overall project: the light rail line alignment option. The chosen alignment option runs along Barbur Boulevard, with a focus on a one-mile-long segment, south of downtown Portland. This particular alignment option was chosen for the purpose of addressing the issues of stormwater drainage from Barbur Boulevard and Interstate 5 into Stephens Creek. Currently, stormwater that flows into Stephens Creek has a high level of pollutants from the highways. This compromises the quality of the stream and increases erosion and toxic sediment levels in the creek. The objective of ALBA Consulting’s portion of the project is to provide TriMet with stormwater designs and analyses for the Barbur Boulevard alignment option. This information can be used to assist TriMet with their design of the alignment along Barbur Boulevard, with the goal of treating and detaining stormwater onsite to meet the criteria of predevelopment discharge levels. Treating stormwater onsite reduces the load on the conveyance pipes and helps recharge the groundwater system. The stormwater from the chosen section of the boulevard will then be discharged at the approved outfall for Stephens Creek. By treating the stormwater from the possible expansion on the boulevard, improvements in the water quality at Stephens Creek are expected. ALBA Consulting focused on the preliminary design of planters and ponds for this project. Planters and ponds were chosen because of their low maintenance costs, ability to improve greenspace, and effectiveness at managing stormwater. The recommendation is planters are placed along the length of Barbur Boulevard to meet pollution reduction requirements. Since planters alone will not meet detention requirements (due to low soil infiltration rates in the surrounding area), ponds were chosen as the preferred facility to meet detention requirements. Therefore, the preliminary design of one planter and one pond was conducted. The locations of potential planters along the length of the boulevard were identified, as well as two additional pond locations. Due to elevation and space constraints along the new road development, no location large enough to install one pond to detain all the stormwater from this section was found on the boulevard itself. As a result, the design of one pond was selected to treat water from approximately one-third of the road section in the southeastern end of the area. Additional ponds or other detention facilities will be needed to meet the total detention requirements for the stormwater from this section of Barbur Boulevard as well. The planter that was designed using a presumptive approach calculator online showed that the planter was able to meet pollution reductions requirements. Based on this information, it is assumed that planters placed along the length of the boulevard will be adequate to meet the total pollution reduction requirements of the road section considered. The information provided in this report is intended to be used as a preliminary design for stormwater detention and treatment along Barbur Boulevard if this alignment option is chosen. All designs were based on preliminary site assessments from previous geotechnical reports of the surrounding area as well as a hydrograph based on estimated values for the Portland area as found from the Stormwater Management Manual (SWMM, 2016). Further analysis of the site should be conducted in order to ensure that all facilities are sized appropriately.Item Open Access Walkability and Placemaking in Tigard(2017) Shinners, Dana Marie; Goodman, Elizabeth; Knudson, Kaarin; Margerum, Richard; Parker, Bob; Sandoval, GerardoTriMet and the city of Tigard partnered with the Department of Planning, Public Policy, and Management and the Sustainable City Year Program to plan for the possibility of extending light rail to the city. The four areas of focus were: Affordable housing, Placemaking in Downtown Tigard, Placemaking in Tigard Triangle and The Red Rock Creek Corridor. This report includes the methodology, findings, and recommendations to support growth in Tigard. In each section, the recommendations appear first, followed by research, data, and implementation details. Supplemental materials are found in the Appendix. This format follows the city staff recommendation to focus on innovative ideas that will spur community participation. These ideas include: addressing long-term affordable and stable housing, encouraging arts and events downtown, a Triangle Public Market, creek restoration opportunities, and meaningful public engagement methods.
