Steve Intro Where and Who
Where is Portland Oregon?
Who are we?
Sean-- Sustainability
Sustainability-Define
Sustainability why important List, but hit $/bottom line slide from prior AWPA presentation?
Sustainability-region and agency commitment and experience (examples)
Sustainability why important
Key Example-Rose Qtr Pervious Pavers (IMAX)
TriMet- The Region s Transit Agency
MAX Light Rail system Yellow Line - Interstate 2004 Red Line - Airport 2001 WES 2009 Green Line I-205 & Portland Mall 2009 Westside - Hillsboro 1998 Blue Line - Gresham 1986
Portland to Milwaukie 7.3-mile light rail extension Up to 25,500 weekday rides by 2030 Improved light rail, bus, streetcar, bike/ped and freight service Two Park & Ride lots Up to 460 bike spaces New multi-modal bridge Up to 14,000 jobs
Portland to Milwaukie- A Fully Modal Project Shared Transitway Peds and Bikes
Mature Urban Neighborhood Slide
Context-History of Interventions Urban Renewal vs stitching.sustainable
Context-Trees and Green Streets Picture of mature trees Picture/ state of play about municipal greenstreets
Context-Urban Street and Platform Urban Drivers and Diagram LINCOLN

Stevesustainable elements
State of the Art Green Street
Sustainable element- ped and bike access
Sustainable element- stormwater planters
Sustainable element- pervious paving
Centerpiece Sustainable element- Ecotrack
A Merger: Ecoroof Embedded T-Rail Paved Track (Yellow Line)
Goals and considerations minimize and accommodate maintenance support and meet local land use permit requirements and be aesthetically pleasing be sustainable facilitate track inspection ensure track tolerances were maintained reduce stray current be constructible provide reliable track structure minimize the section depth facilitate positive drainage. allow retrofit/removal (if pilot project deemed unsuccessful)
Ecotrack-Range of Alternatives
Ecotrack- Selected Alternative (Alt F)
Landscape elements Vegetation Sedums Drought tolerant succulents mediterranean climate Adaptive/proven on ecoroofs Varieties for low growing Multiple varieties for diversity and aesthetics Availability/use of mats instant; erosion control Soil Irrigation High quality import topsoil Relatively thick (for planting on structure) Subsurface irrigation system no spray on rails Control valve timers/clocks Vaults and boxes bolted to slab
Summary of Features and Benefits Exposed Rails Features and Anticipated Benefits Feature Benefit ease of inspection ease of maintenance reduce stray current Eliminate Tie and Ballast Slab supported D.F. track Foundation drain mat Subsurface irrigation Sedum mats reduce maintenance for line and grade eliminate need for tamping eliminate fouling of ballast avoid settlement issues positive drainage even load distribution compatibility with vibration mitigation positive drainage of plant medium no wetting of rail head less prone to vandalism Appropriate plant (climate, soil section, in trackway) "Instant" soil coverage
Project Schedule and Status Ecotrack civil and track is under construction Planting anticipated Winter 2014/15 Open for Revenue Service September 2015
