Two Railway Station Projects in Italy Earn Envision Silver Awards

ICMQ, ISI’s partner in Italy, has announced that two railway stations along the Adriatic Coast have earned Envision Silver awards in recognition of their sustainable redevelopment efforts. These two projects represent one half of the four total pilot projects chosen by Rete Ferroviaria Italiana (RFI), the owner of Italy’s railway network, to be certified using the Envision framework and rating system for sustainable infrastructure. The RFI team chose to use the Envision framework to better orient all project stakeholders toward a perspective that incorporates historical, environmental, social, and economic sustainability throughout the planning, design, and implementation of these renovation projects.

The renovation of the Cattolica Railway Station, located near the historic center of Cattolica, Italy, will allow it play a progressively more central role in the community. Instead of serving only as a transit area, it will now provide better amenities for pedestrians and other visitors, as well as an improved connection to the local city park. The front courtyard will offer more green space, irrigated by a new rainwater storage tank system, and space will be dedicated for electric vehicle charging stations and a new Velo Station to encourage alternative transportation. The renovation will utilize sustainable building materials, and photovoltaic panels will be installed on the new shelters to generate energy on site.

The Pesaro Railway Station, the main station in the Italian province of Pesaro-Urbino, is strategically located near the seaside, the city park, and the city’s historic center. This location allows the station to serve as one of the main gateways into Pesaro, which has been recognized as the Italian Capital of Culture for 2024. The renovation of this station will improve integration with the surrounding community through more connected roadways and greater access to alternative transportation options, like bicycles. It also represents part of a larger effort to integrate two parts of the city, which are currently divided by the bundle of railway tracks. The railway station building, shelters, underpass, and platforms will be upgraded to facilitate more functional passenger services, and the outdoor areas will be enhanced to promote better access and improved safety, livability, and attractiveness. The project team has also planned to optimize water and energy consumption, as well as reduce greenhouse gas emissions, throughout the development and lifespan of the project. This station will serve as the hub of an integrated and sustainable “Mobility as a Service” (Maas) system, becoming a key part of the urban framework and enhancing Pesaro’s quality of life and commercial appeal.

These innovative railway station renovations represent environmental, social, and economic sustainability improvements that will create better access to the stations and improved integration with the surrounding communities, while reducing vehicular traffic and enhancing quality of life for the local neighborhoods.

Lower Manhattan Coastal Resiliency Project Earns Envision Platinum Award

Washington, D.C. and New York City — The Lower Manhattan Coastal Resiliency – Battery project located in New York, New York, has earned an Envision Platinum award. This project is part of the larger Lower Manhattan Coastal Resilience initiative aimed at reducing flood risk from coastal storms and sea level rise. Led by the New York City Economic Development Corporation (NYCEDC) on behalf of the New York City Department of Parks & Recreation (NYC Parks) and the Mayors of Climate and Environmental Justice (MOCEJ), this project will rebuild the existing deteriorating wharf structure at a higher elevation to protect against sea level rise while integrating it with the iconic waterfront park at the southern tip of Manhattan.  

The Battery is home to extensive gardens, artwork, and cultural landmarks and is the departure point for vessels taking thousands of passengers every year to the Statue of Liberty. The project will ensure the waterfront’s resilience over the next 80 years while promoting sustainable and resilient infrastructure in Lower Manhattan, a vital district of New York City. The Envision framework was used throughout the project’s development to track and improve sustainability performance. Exploring opportunities across key themes such as reducing embodied carbon, managing stormwater quantity and quality, and minimizing waste sent to landfills resulted in several innovative strategies. These strategies include reusing site materials, utilizing locally sourced and low-carbon materials, and investigating transportation alternatives that reduce emissions and pollutants. 

Among the unique features of the wharf design is the multi-level slip design that provides universal access to vessels with varying freeboard heights for the wide range of sea level elevations at the wharf from the present day to 2100. This adaptive design provides flexibility for uncertain future conditions while preserving views of the Harbor, architectural details, and the character of the existing beloved park. 

Material reuse and waste management were drivers of the design, which incorporates significant quantities of granite, metals, and wood from the existing site and provides a hierarchy for removals that prioritizes reuse and recycling and minimizes landfill waste. Plantings in the harsh waterfront environment were specified for salt tolerance and anticipated increasing urban heat, while maintaining the colorful perennial variety throughout the seasons that characterizes the larger park design. 

The project will contribute to long-term community goals by addressing the impending sea level rise, restoring the wharf conditions for continued safe usability, and preserving The Battery’s iconic and historic character. Construction is being divided into two phases of partial wharf closures to minimize disruptions to park and ferry activity to and from Liberty and Ellis Islands, with project completion targeted for 2026.

Verified Sustainability Achievements

Address Climate Change VulnerabilityIn 2012, Hurricane Sandy devastated New York City, flooding 17% of the land and claiming 43 lives. The storm affected 400 buildings, impacted transportation assets, interrupted power supply, closed parks, released 5.2 billion gallons of untreated sewage into the city’s waterways, and ultimately caused $19 billion in damages. After the storm, the Lower Manhattan Climate Resilience Study assessed the vulnerability of the community to climate change by identifying climate hazards (sea level rise, groundwater table rise, storm surge, extreme precipitation, and heat waves) and mapping them against the city’s infrastructure systems. The study identified five key projects in the Lower Manhattan Coastal Resiliency program that would improve the community’s resiliency against these climate threats. The five projects, including the Battery Coastal Resilience, will comprise a connected network of infrastructure projects along Lower Manhattan’s waterfront to improve the community’s resiliency to a changing climate. The project team’s emphasis on improving resilience was recognized with high levels of achievement across this Envision achievement area.

Climate Adaptive Design – One of the most unique aspects of the project is the slip design which integrates the elevated waterfront platform, designed for future sea level rise conditions, with ferry access points, designed for current sea levels and vessel operations. The innovative multi-level slip design allows for flexibility over the near and long-term operations of the wharf by considering daily tidal swings, varying sized vessel berthing, accessibility, and sea level rise, balanced with maintaining the park’s character and waterfront experience. The slip design is easily able to be adapted for future sea level rise conditions with higher platforms integrated into the existing design, limiting disruptions to long-term wharf operations while meeting current and future wharf needs.

Embodied Carbon Reduction – Early in design, NYCEDC and NYC Parks established a sustainability charter that included the goal to quantify and reduce the overall embodied carbon emissions of the project. To further this goal, Stantec developed an embodied carbon baseline to help the project team understand the major material contributors to the project’s emissions sources. Stantec’s Climate Solutions team also developed embodied carbon-based procurement for concrete and a tool that would allow construction partners to calculate the Global Warming Potential (GWP) of their concrete mixes to stay within a defined GWP budget. The project’s construction partner, Hunter Roberts, identified opportunities to use alternative modes of transportation such as barging material and equipment to site that would reduce carbon emissions and take trucks off congested New York City streets. In the end, the project team estimates a 54% reduction in embodied carbon emissions compared to the baseline.

Sustainable Resource Management – The project team used the Envision framework as a roadmap to organize sustainability initiatives, track performance, and assign task responsibility. Among these key initiatives is the implementation of amaterial management plan centered on reducing environmental impacts related to the extraction, refinement, and transport of construction materials. Strategies included reusing existing materials, using less materials, using recycled materials, and selecting more sustainable alternatives. Guided by this approach, the team selected a recycled fill material that significantly reduced the project’s embodied carbon in comparison to typical engineered fill materials. These earthwork improvements resulted in an estimated $3 million savings for the project. Additionally, the project will divert at least 75% of its nonhazardous construction waste from landfills to instead be reused, recycled, or otherwise salvaged.

Enhanced Public Space & Restored Artwork – The Battery is one of New York City’s signature parks — home to several historic and cultural resources, offering iconic views of the Hudson and East Rivers, and providing ferry access to the Statue of Liberty. To protect and enhance the park’s defining characteristics, the project team consulted with a variety of community stakeholders, including New York’s State Historic Preservation Office (SHPO), the Stockbridge-Munsee Indigenous Group, the Maritime Association of New York, the National Park Service, and even original artists. Together, they identified and evaluated the resources that may be impacted by this project and developed a plan to preserve and revitalize them. Continuous consultation with community stakeholders also led to the development of plans to improve pedestrian accessibility throughout the park, update public seating to better enjoy the views, and preserve existing trees and gardens.


“The Lower Manhattan Coastal Resiliency (LMCR) project sets the standard for future projects of this kind, marrying coastal protection with an ambitious sustainability agenda,” said New York City Economic Development Corporation (NYCEDC) President & CEO, Andrew Kimball. “NYCEDC is proud of LMCR and the teams involved for receiving the Envision Platinum Award all in an effort to create a cleaner, greener New York City.”
“With sea levels rising and storms growing stronger and more frequent, it is vital that we invest in protecting our city from the effects of climate change,” said Sue Donoghue, Commissioner of New York City Department of Parks and Recreation. “Our innovative plans for the Battery are helping to ensure that the Lower Manhattan waterfront is well-prepared for the 21st century’s extreme weather and rising tides, without sacrificing New Yorkers’ access to this historic and beloved greenspace. The challenges of climate change affect cities across the country and around the world, and I’m so proud that New York City is setting an example with this creative and exciting approach, which rebuilds our critical infrastructure while minimizing waste and utilizing local, recycled materials.”

“As New York City advances coastal resilience projects in a dense urban environment, it is essential that we minimize harmful emissions from our construction and waste sent to landfills,” said Mayor’s Office of Climate & Environmental Justice Executive Director, Elijah Hutchinson. “With NYCEDC’s Envision Platinum Award, the city has met and exceeded our Clean Construction Accelerator goal of reducing embodied emissions in infrastructure projects by 50%.”

“The Battery protected Manhattan against threats from the sea when its shoreline forts deterred foreign navies,” explained Warrie Price, President and Founder of The Battery Conservancy. “Today, The Battery is called to serve again – to defend the city we love from the sea itself. The Battery Conservancy is proud to work with New York’s leadership to ensure that this storied public space will continue to attract and comfort water-gazers and garden-lovers.”

“With The Battery’s rich history and cultural significance, this project demanded a holistic approach to sustainable and resilient design,” remarked Greg Sprich, Principal at Stantec Consulting Services Inc. “The team rose to the challenge and delivered a project that not only provides much needed coastal protection to lower Manhattan, but also serves as a case study for reducing waste and embodied carbon for future infrastructure projects.”

“Resilient and sustainable environments are the result of collective effort and vision, which is at the core of the Lower Manhattan Coastal Resiliency – Battery Project,” said Ethan Smith, Project Manager and Envision Lead at Hunter Roberts Construction Group. “This award recognizes the extensive planning, design, and coordination efforts made by the team to showcase sustainable, resilient infrastructure and green construction practices.”
“As communities invest in infrastructure projects, it’s crucial to incorporate sustainable and resilient features that account for the projected impacts of climate change,” said Kristi Wamstad, ISI Verification Director. “This project is an outstanding demonstration of how a project team can successfully work with a variety of community stakeholders to assess infrastructure vulnerability and use the Envision framework to plan for resiliency.”

Gronda di Genova Project Achieves Envision Gold Award

ISI’s Italian partner, ICMQ, has awarded the Gronda di Genova project Envision Gold for sustainability. The project doubles a section of highway that passes through the Genoa region of Italy, from the Polcevera Valley to the town of Vesima, separating city traffic from heavy and transiting traffic, while connecting key interchanges along the route. This will allow for better flow and less congestion, and will support local economic growth.

A 4.25 billion $USD project, the Gronda di Genova includes 13 new road bridges and the expansion of 11 existing viaducts. The region’s complex, mountainous terrain means that much of the new road system will be underground, a strategy that minimizes land consumption and reduces the impact on existing infrastructure. The project includes a total of 30 tunnels, accounting for a distance of approximately 50 km (more than 30 miles) — representing 81 percent of the new stretch of highway.

This Envision award confirms the results of a design that was carefully planned in collaboration with the community and aligned with national and international sustainability guidelines. The Gronda di Genova will improve traffic conditions — reducing travel time by 3.5 million hours per year for users of the highway and local road system in the Genoa area — but will also address multiple interrelated sustainability issues. These include land use conservation, sustainable use of resources for construction, engagement with stakeholders for project development, energy production from renewable sources, and careful design of green works.

The project also adds significant environmental mitigations that are tied to broader urban renewal goals. These involve final landscaping, civil arrangements, and renaturalization of slopes for the tunnel entrance areas, restoration of service roads and construction site areas, as well as initiatives for urban regeneration. These initiatives include the restoration of a depleted quarry area and two architectural restoration projects in the cemetery in Voltri and in the valley of the Leiro stream in Voltri.

Land excavated for the tunnels of the Gronda di Genova was used to fill the Calma Canal and expand the airport runway, known as the Opera a Mare. This newly constructed land now also hosts a photovoltaic park built to generate enough energy to power the Gronda and provide excess energy to the community.

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.
