2 terms

storm surge barriers technical

"The designs will include storm surge barriers, floodwalls and levees"

Large, movable coastal defenses—often gates, walls, or sluices—designed to close off waterways and protect low-lying land from unusually high tides and storm-driven waves. They matter to investors because they reduce flood risk for ports, industrial sites, real estate and infrastructure, which affects asset values, operating continuity, insurance costs and public spending priorities; think of them as giant shutters a coastline can pull closed during a storm.

living shorelines technical

"Nature-based features, including living shorelines and oyster reefs"

A living shoreline is a coastal erosion and flood-management approach that uses plants, natural materials, and sometimes engineered structures (like oyster reefs or coir logs) to stabilize shorelines while preserving or restoring habitat. Like a living fence made of marshes and reefs instead of concrete, it reduces wave energy and erosion and can influence permitting, government funding, and the long-term value or resilience of coastal assets — factors investors monitor around coastal development and environmental projects.

EDMONTON, Alberta and CHARLESTON, S.C., July 30, 2026 (GLOBE NEWSWIRE) --  TSX, NYSE:STN

Stantec, a global leader in sustainable design and engineering, has been awarded a US$150 million joint venture contract by the U.S. Army Corps of Engineers, Charleston District (USACE) to design critical infrastructure supporting coastal storm risk management on the Charleston peninsula—an important step in safeguarding one of the United States’ historic coastal communities.

In partnership with Johnson, Mirmiran and Thompson (JMT), Stantec will deliver a more resilient future for Charleston; protecting its people, while preserving the history and character that define the community. This award highlights Stantec’s leadership in coastal resilience and strengthens its position to grow work with USACE and regional partners in major coastal metropolitan markets.

With a total program value of US$1.2 billion, the team will lead the design of more than eight miles of integrated coastal infrastructure across Charleston’s waterfront. The designs will include storm surge barriers, floodwalls and levees, pump stations, and multiple gate structures for pedestrians, as well as vehicle, rail, and tidal flow management. Nature-based features, including living shorelines and oyster reefs, are also incorporated to support long-term system performance and environmental function.

Home to more than 40,000 full-time residents and nationally significant historic landmarks, Charleston faces increasing vulnerability from storm surge. The project will place public safety first by designing a multi-purpose storm surge defense system that will protect life, infrastructure and the community for generations to come.

Resilience for historic coastal communities
“We’re proud to partner with USACE on a project that will help protect Charleston’s rich history, vibrant communities, and remarkable ecosystems,” said Chris Williams, senior vice president for Stantec’s US Federal Program. “Our Water, Infrastructure, and Environmental Services teams will combine their expertise to design solutions that strengthen resilience while respecting the region’s environmental and cultural fabric.”

“The USACE Charleston Coastal Storm Risk Management Project demonstrates what can be achieved when visionary local leadership is paired with federal investment,” said Chris Mack, director of Resilience and Coastal Solutions at JMT. “The City of Charleston has spent years advancing resilience and sustainability initiatives across the peninsula, and JMT is proud to support USACE’s leadership in delivering this transformative project.”

Stantec brings proven experience from multiple major U.S. coastal storm risk management programs, including work across the Gulf and Atlantic coasts. For example, the firm served as the designer of record for three storm drainage pump stations, floodwalls, levees, and gates for USACE’s Permanent Canal Closures and Pumps Project in New Orleans. Stantec also partnered with the New York City Economic Development Corporation to provide adaptive designs that support flexibility and resiliency to protect the Battery’s waterfront. In Texas, the firm provided engineering and design services for a 26.7-mile coastal levee and floodwall system near Galveston following Hurricane Harvey.
