Ship Canal Water Quality Project in Seattle Earns Envision Platinum Rating

13-December-2022

Seattle Public Utilities’ Ship Canal Water Quality Project has been awarded Envision Platinum for sustainability. This project had verified achievements across several areas of the Envision framework, and in particular, it will bring significant water quality improvements to prevent 75 million gallons of polluted stormwater and sewage from entering the region’s waterways on average each year.

Public Utilities and King County’s Wastewater Treatment Division are completing an underground storage tunnel to reduce the amount of polluted stormwater runoff and sewage that flows in the Lake Washington Ship Canal, Salmon Bay, and Lake Union from the sewer system.

In some parts of Seattle (as with many other places), stormwater and sewage share a set of pipes — a combined sewer system which, during heavy storm/rain events, overflows when pipe capacity is exceeded. Untreated sewage and stormwater then flow directly into the Ship Canal, posing public health concerns and harming fish, wildlife, and the environment. The Ship Canal Water Quality Project is crucial for keeping the waterways clean and protecting human health and the environment over the long term.

This project is funded in part by the Washington State Department of Ecology and the Environmental Protection Agency through the State Revolving Fund and Water Infrastructure Finance and Innovation Act loans. The project’s 2.7-mile, 18’10”-diameter tunnel will be able to capture and temporarily hold more than 29 million gallons of stormwater and sewage during heavy rains. As the heavy rains subside, flows will be sent to King County’s West Point Wastewater Treatment Plant in Magnolia for treatment.

Sound Transit’s new light rail project that will bring service to downtown Redmond, Washington, has been awarded an Envision Platinum Award, with sustainable achievements across five areas of Envision. Sound Transit is building the extension with parters who include Jacobs (Lead Design Firm), Stacy and Witbeck/Kuney, a Joint Venture; WSP, Hatch LTK, Hensel Phelps, and Modern Railway Systems.

The Downtown Redmond Link Extension Project (DRLE) is a 3.4-mile light rail extension that includes new surface and elevated guideway structures, stations at Marymoor Village and Downtown Redmond, a parking garage, and associated utility, drainage, environmental, and roadway improvements. Currently under construction, this project will extend Sound Transit’s 2 line from the future Redmond Technology Station providing residents and commuters in Redmond with direct light rail service to Overlake, Bellevue, Mercer Island, downtown Seattle, the University of Washington, Northgate, Lynnwood, SeaTac Airport and Federal Way.

York Region’s 2nd Concession Project receives Envision Bronze Award

6-December-2022

ISI has awarded an Envision Bronze Award for sustainable infrastructure to the 2nd Concession Project, a major north-south arterial corridor under the jurisdiction of the Regional Municipality of York (York Region). Located in the Town of East Gwillimbury, this is the second project in Ontario to earn an Envision award for sustainability and the first project in the transportation sector in the province to do so.

The project in brief

The 2nd Concession project—the largest project ever undertaken by York Region’s Transportation Services Department—was a necessary investment in infrastructure to accommodate the tremendous growth in York Region and the Town of East Gwillimbury in particular. The six-kilometer corridor, extending from Bristol Road to Queensville Sideroad, crosses the Rogers Reservoir, a popular conservation area and recreational trail in the East Holland River watershed, which the Lake Simcoe Region Conservation Authority manages.

This project widened the 2nd Concession from two lanes to four and included trails, three bridges, retaining walls, active transportation facilities, and stormwater management.

Some of the unique elements of this project included:

—An elevated wooden boardwalk through wetlands and marshes connecting forests with growing residential communities.
—Benches, bike racks, and a flagstone meeting area.
—A wooden-clad pedestrian bridge in the Rogers Reservoir overlooks the historic canal and lock system, which the project protected and preserved.
—Bridges spanning an active rail corridor and the Holland River.
—Curvilinear and terraced tree-patterned retaining walls.
—Dedicated cycle tracks (the first in the Region).

Quotes

“Congratulations to York Region and its project partners on earning an Envision Bronze award for sustainable infrastructure for the 2nd Concession project. This award results from tremendous teamwork, leadership, and community collaboration. Everyone in the area should be proud of this achievement. Protecting and enhancing the corridor area as an important resource for residents was given high priority in the planning and construction of the project, with a context-sensitive design maintaining or improving the natural systems and community quality of life aspects receiving careful attention.”
—  Melissa Peneycad, ISI’s managing director.

“Yesterday was the first time we took our dogs for a walk along 2nd Concession. The view from the bridge is amazing. The viewing platforms on the bridge are a nice touch. The boardwalk for the trail blends in well with the environment. You and your staff have done a wonderful job on this project.”

— R.W. a long-time resident living in the project corridor

This project had verified sustainability achievements in the following areas, among others: meaningful stakeholder engagement; improved infrastructure integration; improved mobility, safety and access; and wetland restoration.
