  • Review what sustainability is, what it means, and give examples of what it can mean for transit.Most people focus on the environmental aspectsNot forget the Social benefits - improved service, diversity,accessibility, public art, safety programsSustainable Transportation=Low environmental impactLivable communitiesFiscally responsible, economic prosperity along alignment/transit corridors
  • Recycled Content Recycled tires in sound walls saved over 9000 tires from going into a landfill on I205 Recycled plastic bollards and chains on Interstate project – saving money and also improving safety (no stray current issues)Material Reuse Reuse of concrete and asphalt on Interstate project, saving time and money (hauling, disposal costs and cost for fresh material)
  • Lots of opportunities with so many properties being acquired and demo’d – deconstruction opportunities, older homes with potentially high value materials. Deconstructing may also support DBE utilization opportunities.Build upon our great experience on the Mall project with salvaging and reusing materials elsewhere.Rockwood – using Mall granite as bollards between trackways at station.
  • Renewable has been used on art, buildings and shelters. Solar hot water system at Merlo Lift building under constructionInfrastructure in place to attach and operate solar panels and wind turbines as South Terminus to power electrical systems at site.
  • Stormwater effortsIn every new project which warrants inclusion – I-205, including along Johnson CreekDowntown Portland near PSUMerlo Fuel & Wash sitePMLR
  • Landscaping effortsProcure trees early to ensure you get the varietals you need and more mature when they are ready to be planted. Design plants that need lower levels of irrigation and lower maintenance.Select varietals that can thrive in urban environmentBegan using “smart irrigation controls” on I205 that utilize specific site characteristics (soil type, plants, slope) and real time weather data to control amount and timing of irrigation, optimizing water use.
  • Energy – Building a light rail project that will used a lot of energy, so incorporating energy savings in the design can make a big impact in ongoing operations.Water – Since this project is adjacent to many water bodies, there are many opportunities to reduce impacts to water quality and habitat.Materials - Large public works project with lots materials and embodied energy in those materials. Also repetitive opportunities, where a small change in material selection at one station can have a ripple effect along the alignment and make a bigger impact.
  • Already utilize regenerative breaking for train to train kinetic energy reuse.What’s not utilized right away is lost as heat – storage would save the energy for reuse.We don’t lose much downtown since we have such short headways, but there may be opportunities as you move out in the system.
  • Humped tracks utilizes gravitational forces to slow trains down into a station and assist in acceleration, reducing the energy needed to stop and start the train.
  • Already have a good experience and a lot ofstormwater features planned – bioswales, sustainable landscaping.Further explore this option at Park and Rides or around stations or signal/comm buildings.High visibility for public.
  • Paris T3 LineAnother, stormwater infiltration opportunity.Also high visibility for customers and demonstrates sustainability.Does not have to be grass, could be any kind of vegetated ground cover. Ballasted track essentially performs the same thing, but this is more aesthetically pleasing.Pedestrian safety, operational maintenance needs to be considered.
  • Think in terms of building a transit system that will be around for a very long time.Example: using stainless steel features – higher cost but longer life and less maintenance
  • Community Investment opportunities are already in the works (TOD, CPTED)Already have an aggressive bike program with this project.How people to get to transit is an key piece of the sustainability puzzle. PMLR: Important to continue to improve the bike/pedestrian connections considering the Springwater Corridor and Trolley Trail.
  • Urban Ecology & HabitatAlready have plans for water shed/ecosystem protection, tree preservation - next step is to focus on providing habitat.Nature in Neighbohoods grant for Park & Ride and Courtney Springs Creek area adjacent to Park Ave. Station
