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.

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

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).


“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.

New resource! Release of an Envision-verified Project Submission

The most comprehensive project example provided by ISI to date comes from this intermodal transit center project located in the Berryessa district of San Jose, California

For the first time, specific details and Envision documentation from a verified project have been made available as a resource to help other Envision users. This resource includes the Envision scorecard and several Envision credit submittals—including coversheets and supporting documentation—for the Berryessa Transit Center Project, which was awarded Envision Platinum in March 2021.

The project’s owner, Santa Clara Valley Transportation Authority, and the lead Envision firm for the project, Keish Environmental, have graciously granted permission to ISI to release their Envision project submission, and it’s now available as a resource to anyone with an ISI account. A link to the materials can be found on users’ dashboards under “Verification Resources” after logging into the ISI site:

Every Envision-verified project is different, with a specific context, requirements, and aspirations that cannot be easily extrapolated to another project. Still, the specificity of an actual project example can be tremendously valuable in adding a further layer of insight and visibility into the verification process.

Applicants are expected to find this resource very instructive, as it makes available the written responses and supporting documentation used to meet Envision requirements during project verification.

“The example provides all the materials submitted by the Berryessa project for seven Envision v3 credits,” notes Kristi Wamstad, ISI’s verification director. “It also includes verifier comments and additional documentation from the project team’s resubmission for the second review. This resource really offers Envision users an authentic insight into the verification process.”

“We are indebted to Santa Clara Valley Transportation Authority and Keish Environmental for granting permission to make available their project submission, as this is easily the most comprehensive project example provided by ISI to date,” said Melissa Peneycad, ISI’s managing director.

Berryessa Transit Center: A stand-out example Envision project

There’s also excitement across the Envision community about the high caliber of the first project to be made public. The Platinum-Awarded Berryessa Transit Center delivered diverse, interrelated benefits for environmental justice, restoration of the natural world, adding public space and amenities, improving local character, improving the community’s long-term sustainability, and more.

As ISI’s award announcement highlighted last year, this intermodal transit center located in the Berryessa district of San Jose, California, is a shining example of integrating sustainability in as much of the project footprint as possible, from EV chargers – to a new, multi-modal trail – to habitat restoration in an urban environment – to a contemplative garden honoring the Muwekma Ohlone Tribe of the San Francisco Bay Area.

“We’re thrilled to have the first Envision-verified project to be shared as a unique resource that can accelerate the use of Envision to evaluate and deliver on sustainability,” said Ann Calnan, Manager of Environmental Programs at Santa Clara Valley Transportation Authority.

“It is an honor to be able to ‘go public’ with a project that I am so proud to have worked on, complete with the supporting documentation, knowing how this may assist other Envision users in preparing their projects for verification,” said Rachael Keish, CEO of Keish Environmental.

ISI hopes the release of materials from the Berryessa Transit Center project will inspire other project teams to make their project documentation public, as sharing actual project examples can accelerate sustainability practices and the use of Envision as a vital tool for accomplishing that.

While the information provided in this resource does not supersede the guidance and requirements established in the Envision Guidance Manual (v3), the Guide to Envision Verification for Applicants, Credit Amendments (v3), and ISI Policies, ISI believes this example project submission offers valuable support to applicants and opens a new window into the verification process.
