In winter 2019, the Town of Sackville began construction for a naturalized stormwater wet pond near Lorne Street. This naturalized wet pond will store ~40,000 cubic feet of stormwater during major events, which will then slowly be released through existing stormwater infrastructure into the Tantramar River. The goal of the project is to reduce flood risk. The pond is being designed to protect and enhance other ecosystem services, including recreation and habitat space.

New Brunswick Environmental Network’s Supporting Climate Risk Mitigation for Municipalities with Nature-based Infrastructure - Research and Knowledge Initiative.
New Brunswickers are already feeling the impacts of climate change including flooding, more frequent hurricanes, storm surges and erosion. Not only is it urgent to prevent as many of the effects of climate change as possible, but also to prepare for the impacts to come. Nature-based climate solutions that protect and conserve nature while reducing the risks of climate change impacts can be key responses to adapting to climate change that are cost-effective and provide many co-benefits that improve quality of life and wellbeing in communities.
We are looking at developing tools and building capacity to support local governments to implement nature-based climate solutions in communities across the province. To develop this tool, we want to hear your views on nature-based climate infrastructure and what you would like to see in your communities. We want to understand what your communities value in terms of co-benefits of the infrastructure and what your largest areas of concern are in responding to climate change. These solutions should meet your needs and alleviate your concerns in the face of the climate crisis.
This project is at its early stages.

Riverview, NB — The Town of Riverview is pleased to announce that the Mill Creek Naturalized Stormwater Pond project is now complete, thanks to an investment of $800,000 from the Government of Canada through the Canada Housing Infrastructure Fund (CHIF). This new stormwater infrastructure will support future residential development, reduce flood risks, and create long-term environmental benefits for the community.
The project aligns directly with CHIF objectives by building resilient infrastructure that enables higher-density housing in a growing community, and supporting sustainable development to benefit present and future residents.
The Mill Creek Naturalized Stormwater Pond will:
Reduce local flood risks by collecting and managing stormwater from a 39.43-hectare catchment area.
Enable almost 1,000 new housing units in the Carriage Hill area, providing much-needed housing supply to meet Riverview’s growing demand.
Support affordability and density targets by allowing multi-unit housing developments and rezoning applications to move forward.
Improve environmental outcomes through a naturalized design that enhances water quality, supports biodiversity, and reduces erosion over time.
The pond uses wetland vegetation and low-maintenance natural features to filter stormwater naturally before it flows into Mill Creek, reducing long-term environmental impact and supporting healthier waterways.
“Investing in stormwater infrastructure is essential to supporting new housing developments and building strong communities. With the completion of this project, the Town of Riverview can move forward with its ambitious housing goals while better protecting the community and the environment. ” The Honourable Ginette Petitpas Taylor, Member of Parliament for Moncton–Dieppe
Mayor Andrew J. LeBlanc says the project is a major milestone for the Town’s long-term infrastructure planning.
“This project is essential to unlocking Riverview’s future housing supply,” said Mayor LeBlanc. “By investing in sustainable stormwater infrastructure, we are preparing our community for growth, supporting new homes for families, and ensuring our environment is protected for generations to come. This project not only supports much-needed housing growth and modern, resilient infrastructure, but also enhances the experience for Mill Creek trail users with a visually striking natural feature.”
Construction of the naturalized stormwater pond began in the spring of 2025 and is now completed.

Located in Richmond BC, directly across from xʷməθkʷəy̓əm/Musqueam, in the Fraser River Estuary, the Iona Island Wastewater Treatment Plant (IIWWTP) and associated Iona Beach Regional Park (IBRP) Projects will see the critical upgrade of the existing wastewater treatment plant, paired with the transformation of the surrounding 114-hectare regional park. Led by Space2Place for Metro Vancouver, the IIWWTP Projects will restore the ecological processes of the north Sturgeon Bank, by reconnecting the river and sea, creating off-channel habitats, regenerating freshwater wetlands, and restoring upland terrestrial habitats, using ecosystem-based, flood-protection and climate-adaptive strategies.
The IIWWTP Projects were initiated in response to the 2012 Wastewater Systems Effluent Regulations legislation of Canadian federal policy, which aimed at improving water quality. As one of the last plants along North America’s west coast with only primary-level wastewater treatment, the intention of the IIWWTP Projects is to upgrade the existing plant to tertiary-level treatment to meet the new standards using a complementary range of ecological restoration efforts.
As the lead on the Iona Beach Regional Park (IBRP) design, Space2Place developed a compelling vision that complements the treatment plant upgrades to restore ecological processes of the North Sturgeon Bank and protect the diversity of ecosystems on Iona Island. The vision created by Space2place was defined by two core objectives: ecological restoration and climate adaptation.
The complexities of the IIWWTP Projects combine ecological significance, infrastructure needs, jurisdictional complexities, and cultural considerations; as such, the lessons learned from this project and its outcomes have the potential to serve as a significant precedent in landscape architecture design for future large-scale, multi-stakeholder, restoration and climate adaptation initiatives.
One of the most significant outcomes of the project will be protection of sensitive ecologies and restoration of natural systems that have been interrupted by anthropogenic interventions to the island over the last 100 years. When completed, the implementation of breaches in the causeway and jetties, will create a nurturing environment for juvenile salmon transitioning from freshwater to saltwater, and help future out-migrating juvenile salmon access critical rearing habitat. In combination with regenerating and expanding the freshwater wetlands upland areas, biodiversity recovery of species within critical aquatic and terrestrial species, including that of many migrating birds, will be enhanced.

Located along the Bow River in Calgary, Alberta, Dale Hodges Park represents a transformative restoration project that converts the former Klippert gravel pit extraction site into a public park and public artwork installation. A collaboration between O2 Planning and Design and Source2Source, with AECOM, Sans Façon, and the City of Calgary, the project uses sculpted landforms to integrate an innovative stormwater management system with habitat restoration and recreation, to restore the degraded riparian and aquatic habitats, treat stormwater runoff, and introduce new opportunities for public use while making vivid the movement of water through the system.
In 2010, the City of Calgary acquired the former Klippert gravel pit, located along the northern bank of the Bow River within Bowmont Park. At the time, Calgary was experiencing rapid growth and development pressure. The acquisition of these lands presented an opportunity for the treatment of stormwater from an intensively urbanized catchment of over 1800 hectares before entering the Bow River, which would not only see the transformation of the ecosystem into a functional habitat for wildlife, but also the enhancement of community amenities and access to nature.
The project was completed in the fall of 2018, opening officially as Dale Hodges Park in June 2019. Once a contaminated gravel pit, the site has now been remediated and transformed into a functional, natural space that not only treats stormwater, but facilitates biodiversity recovery and climate resilience, while using landform art as a high-performance public space.
The success of the project illustrates the value of orchestrating complex, cross-disciplinary teams, showcasing the importance of visionary planning, strong governance, and collaboration as essential for the successful delivery of large-scale urban ecological infrastructure projects. The project employed a systems-based approach to restoring the landscape to fit within its novel ecological and cultural context, inherently advancing long-term biodiversity recovery. Emergent vegetation zones provide natural stormwater filtrations, enhance habitat, and contribute to the ecosystem’s climate resilience. Biodiversity, particularly the presence of trout and numerous native bird species, continues to serve as key indicators of the project’s ecological performance.

Located in Toronto’s southeastern downtown waterfront, the Port Lands Flood Protection Project (PLFP), is a large-scale transformative climate adaptation and urban revitalization initiative to protect over 290 hectares of land from flooding and re-naturalize the mouth of the Don River at Lake Ontario. By creating a new river valley through green infrastructure and wetland ecosystems, the project will establish flood protection and remediate the former brownfield site into a resilient, biodiverse, mixed-use waterfront community. Funded by the federal, provincial and municipal governments and led by Waterfront Toronto with lead designers Michael Van Valkenburgh Associates Inc., the PLFP Project is the cornerstone of Toronto’s larger waterfront revitalization plan to establish climate resilience, restore critical habitat, and enable growth for sustainable development.
For thousands of years, the Don River has flowed into Lake Ontario through one of the largest freshwater marshes in the Great Lakes region. Home to a diverse array of plant and animal species, this wetland long served as a gathering space for Indigenous peoples, but was radically impacted by industrialization in the 19th century, altering the river and removing its natural resilience.
Beginning in the 1880’s, large sections of the wetland were gradually drained and infilled to support industrial and shipping operations, creating what is now known as the Port Lands. This significantly degraded the natural ecology and disrupted the hydrology, impacting the river's connection to Lake Ontario. Industrial pressures eventually forced the mouth of the Don River into a narrow 60-foot-wide channel that became heavily polluted.
This project aims to restore the landscape’s natural resilience lost through urbanization by using bioengineering and nature-based systems to restore the river valley and recreate valuable habitat. In doing so, the project will not only establish flood protection, but also help to mitigate effects of urban heating due to global warming by creating microclimates and providing access to cooler natural areas.
Renaturalizing the mouth of the Don River represents an internationally significant undertaking. Its scale, ambition, and holistic approach set a precedent for climate-resilient urban design, ecological restoration, and integrated public space.
In addition to remediating the lands and the ecology, mitigating the flood risks across the Port Lands will protect communities and important public infrastructure from future extreme weather events. This $1.4 billion investment is expected to catalyze billions of dollars in private investment, reducing the financial risks of climate impacts to governments.
A key lesson emerging from the project is how crucial adaptability is for the successful delivery of large, long-term multi-phase projects. Adaptability in the design process is reflective of the project’s core principles of reconciliation and reconnection for resilience, and is evident in the design decisions, integration, and established ecological systems.

Les Lieux Publics Bonaventure is an urban redevelopment project that transformed the former elevated Bonaventure Expressway into an at-grade green boulevard and public space. Led by Rousseau Lefebvre, the project reconnects the adjacent districts, enhances active and multi-modal transportation, and introduces green infrastructure for stormwater and micro-climate regulation. Beyond these primary goals, the project also enhances community health and wellbeing through the creation of a new public park space offering opportunities for social connection and the integration of public art in urban development at the entrance to downtown Montreal.
For over 50 years, the elevated Bonaventure Expressway served as the main gateway to downtown Montreal. Originally built for the 1967 World’s Fair, the expressway was a significant urban landmark, but its development created a physical barrier between the adjacent neighbourhoods and reinforced car-centric infrastructure in the city centre. Rather than investing to extend its life, in 2015 the City of Montreal decided to demolish the expressway in favour of a new green promenade that stretches nearly six city blocks.
Stormwater management was a key focus of the project, aiming to more efficiently manage and filter urban runoff on-site, increase permeability, create cooler microclimates to mitigate urban heat, and increase accessibility to nature within a densely developed environment – particularly in a neighbourhood that previously lacked park space. By replacing the large-scale grey infrastructure with green infrastructure, including rain gardens and vegetated islands, the project is able to significantly enhance environmental sustainability and ecological functions (e.g., pollination and carbon sequestration), and support urban wildlife and biodiversity.
The removal of the Bonaventure Expressway opened over three hectares for continuous public space to improve access to nature and foster social connections. In addition to enhancing urban livability and community well-being, it presented a significant opportunity to reduce the reliance on cars in downtown Montreal, reconnect the fragmented neighbourhoods, and create a vibrant entrance to the city centre.
The completed project transformed the formerly industrial corridor into a sustainable urban landscape that reconnects the fragmented community. The new boulevard connects key multi-modal transportation routes, introduces extensive green infrastructure and a variety of new recreational opportunities, and has quickly become a beloved public amenity.
Guided by the SITES certification process, Les Lieux Publics Bonaventure demonstrates measurable resilience through the thriving vegetation, effective stormwater management system, and active public use. The project received silver level certification in the spring of 2018. The boulevard’s extensive greening is projected to increase canopy cover to 27 percent within the next 10 years and will help sequester 4 metric tons of CO2 in the first year alone and over 310 tons across 30 years. The addition of grassed areas, rain gardens, and planting beds serve the adjacent impervious surfaces by capturing and treating runoff, significantly reducing the volume of water that would have otherwise been directed to the municipal stormwater system, and improving groundwater quality.

The Niagara River Coastal Wetland Restoration (NRCWR) Program represents a binational effort between Canada and the U.S. to restore coastal wetlands along key areas of the Niagara River. In Canada, these efforts are led by the Niagara Parks Commission (NPC) under the Remedial Action Plan (RAP) which aims to remove the Niagara River from the Great Lakes: Areas of Concern, through a series of nature-based restoration initiatives on both the Canadian and U.S. sides of the river. Using bioengineering techniques and renaturalizing the river edge, the NRCWR Program will not only improve water quality and see the restoration of essential riparian habitat, but also establish erosion protection along the degraded shoreline.
The NRCWR Program has become a model for climate-informed ecological design, demonstrating that restoring natural form and function can achieve adaptation objectives without relying on hard engineering. Through this initiative, eight wetland sites have been restored resulting in five hectares of wetland habitat, nearly two kilometers of restored shoreline, and over 30,000 native trees, shrubs, and wildflowers planted. Biodiversity recovery was immediate and measurable. Fish populations continue to positively respond to the healthier wetlands with native freshwater fish species showing noticeable improvements, including smallmouth bass, muskellunge, walleye and yellow perch. Early results indicate the return of bird species not seen along the river for over 50 years, further underscoring the effectiveness of these naturalization efforts to support biodiversity recovery.

The Peter Lougheed Wildlife Overpass (PLWO) is a wildlife crossing infrastructure project spanning the Trans-Canada Highway (TCH) in Alberta. Led by DIALOG, the project is the first wildlife overpass in Alberta constructed outside of a national park. Designed to reduce wildlife-vehicle collisions (WVCs), the PLWO provides safe passage for wildlife and motorists along one of the busiest stretches of the TCH, reconnecting the landscape and rich ecology of Canada’s Bow River Valley.
The PLWO has set a precedent for future work in landscape connectivity practices and green infrastructure for the safe passage of humans and wildlife. Using trail cameras, ongoing monitoring focuses on wildlife use which represents a primary indicator of success, as well as a proxy for broader ecosystem health. Wildlife cameras continue to document and monitor wildlife use of the crossing, with early results showing a broader range of species than initially anticipated, including large mammals such as elk, bears, and cougars.
Unlike earlier wildlife crossings constructed in Alberta – all of which are built within national parks – the PLWO was delivered at the provincial level, through coordination between transportation, parks, and other government ministries, as well as front-end collaboration across disciplines including engineers, landscape architects, and wildlife biologists. Having diverse professional perspectives designing animal-first infrastructure was critical to the project's success and represents one of the major lessons from the project. Successful ecological outcomes required careful attention to materials, soil quality, and construction coordination, enabling the landscape to establish and function ecologically over time.

Fredericton is experiencing a period marked by significant population growth and the urban forest remains a crucial component of maintaining the city’s livability. The development of the UFMS was prompted by population growth projections over the next 10 to 20 years. While Fredericton already possessed a strong internal capacity for tree care and management, it lacked a formal, long-term strategy to guide urban forest protection. In 2022, the City of Fredericton proactively commissioned Stantec Consulting Ltd to develop a 25-year urban management strategy for municipal lands, ensuring that growth could continue, while maintaining equitable canopy cover to support long-term climate resilience and ecological health.
The urban forest is defined as all trees within the City of Fredericton including street trees, forests, private lands, parks, and natural areas. Fredericton’s UFMS is part of a broader suite of City-led initiatives to grow responsibly by planning ahead for strategic preservation of existing trees, and planting of new tree species to support a diverse and resilient urban forest. In 2023, Stantec provided the City with the Urban Forest Technical Report (UFTR), summarizing the existing state of Fredericton’s urban forest. The UFMS builds upon the findings of the UFTR, integrating feedback from internal City departments and public engagement processes. The UFMS presents a series of guiding principles and management practices for long-term viability of Fredericton’s urban forest.
Stantec’s development of Fredericton’s UFMS exemplifies the use of open, low-cost and accessible methods, using public datasets and other non-proprietary tools, and presenting a precedent for other cities to replicate without relying on external consultants. The UFMS advances a sustained approach to preventative maintenance, which includes mitigation of storm-related damage, proactive pest management, and the strategic planting of replacement trees. While emerging stressors such as the emerald ash borer and climate change persist, the resilience and long-term health of the urban forest have been significantly strengthened.

Located in Victoria, British Columbia, the Power To Be Basecamp serves as the operational and program centre for the nonprofit organization that works to remove barriers to participation in nature-based experiences. Designed by MDI Landscape Architects, the landscape surrounding the amenity buildings transforms a former golf course on the shore of Prospect Lake into a regenerative community hub that promotes social innovation through inclusive outdoor programming focused on wellbeing, learning, and connecting people with nature.
The Power To Be Basecamp is located on the unceded lands of the W̱SÁNEĆ First Nations and the lək̓ʷəŋən (Lekwungen) People. For 40 years, the site operated as the privately owned 87-acre Prospect Lake Golf Course, ceasing operations in 2015 following the owners’ retirement. At the time, 35 acres were developed for recreational use, with 45 acres of forested lands and the remaining eight acres dedicated as protected lands.
The existing infrastructure remaining from the decommissioned golf course enabled a retrofit of the developed areas, while avoiding additional disturbance to the surrounding ecologically sensitive landscape. This provided Power To Be the opportunity to establish a permanent operational basecamp that supports expanded nature-based programming and advances both the organization’s social mission and the ecological protection and restoration of the site.
The balancing of environmental objectives with accessibility requirements represents a key lesson of the project, where project material choices had to deviate from those that would advance sustainability targets to achieve more inclusive access. In 2024, the Landscape Architecture Foundation conducted a performance series on the Power To Be Basecamp to evaluate the economic, social, and environmental outcomes of the project. The study found that the ecological functioning of the landscape has improved significantly, documenting measurable increases in ecosystem services as well as wildlife observations, including both endangered species and species not previously recorded on site. In addition to improved ecological performance and beneficial social outcomes, hydrological system and water-management improvements – which also contribute to overall economic efficiency – were documented.

The St. George Street Rainway is Vancouver’s largest blue-green corridor, transforming a paved residential street into a multi-block green rainwater infrastructure (GRI) and sustainable transportation corridor. Initiated by community volunteers and advanced by the City of Vancouver, the Rainway integrates stormwater management, urban ecology, active transportation, and public realm benefits. By capturing and treating rainwater at the surface through a series of rain gardens, the Rainway reduces pressure on the sewer system, improves downstream water quality, supports urban biodiversity, and helps cool the neighbourhood during extreme heat.
Prior to urban development, the area surrounding St. George Street was part of a coastal western hemlock forest, where a small creek drained water from the local watershed into False Creek. With urban development, historic streams, like the one on St. George Street were buried to make room for roadways and urban development, altering local hydrology, ecology and the surrounding community’s connection to nature. The Rainway Project was initially envisioned by a group of community volunteers, seeking to restore urban nature, daylight the lost creek, and create new opportunities for art, learning, and neighbourhood gathering. In 2013, City Council approved the Mount Pleasant Community Plan, which laid the foundation for the project and identified St. George Street as a GRI and active transportation corridor.
The final design reallocates 1,100 m2 of road space over four city blocks to nature-based rainwater infrastructure in the form of a connected series of rain gardens. It closes one and a half blocks to cars, creates more spaces for people and nature, and delivers three blocks of dedicated bike lanes suitable for All Ages and Abilities (AAA), helping to fill a key gap in Vancouver’s cycling network. The Rainway also adds 35 new trees, increasing shade and helping to cool the St. George corridor. The project allocates 3,000 m2 of planted area to rainwater infrastructure designed to treat approximately 17,500 m³ and infiltrate 5,000 m³ of rainwater annually. The system is designed to accommodate 90% of Vancouver’s rain events, with additional capacity to enhance resilience during atmospheric river events.

The Saint-Laurent corridor extends from Cavendish Boulevard and Highway 40 to the Bois-de-Liesse and Bois-de-Saraguay parks, passing through ecologically significant woodlands including the Cavendish, Marcel-Laurin, and Cavendish–Raymond-Lasnier–Beaulac–Poirier areas. Historically the site of the former Cartierville Airport, this sector of the borough of Saint-Laurent has long served as a major industrial-commercial hub and as a result, has undergone extensive hardscaping since the 1960s. Over time, the predominantly asphalt surfaces combined with the sparse tree canopy and vegetation cover, created one of the largest urban heat island areas across the region, compromising livability for both people and urban ecology.
The Saint-Laurent Biodiversity Corridor plan is a 20-year-plus vision developed by LAND Italia (today LAND Canada), civiliti, Table Architecture, and Biodiversité Conseil, that serves as an actionable strategy to transform the industrial area of the Saint-Laurent borough, into a continuous urban ecological corridor. Guided by the Corridor de biodiversité de Saint-Laurent: Plan directeur d'aménagement master plan, the 450 hectare project aims to enhance biodiversity and improve Montreal's overall climate resilience using a unique framework of blue-green-social infrastructure, to establish a connected ecological network, manage stormwater, mitigate urban heat, and improve urban livability.
The Saint‑Laurent Biodiversity Corridor master plan represents an innovative approach of integrated blue, green, and social infrastructure. The project uniquely positions local-scale interventions within a larger regional ecological network to support biodiversity, enhance urban livability and connect people with nature, to build a climate-resilient city. The master plan was developed as a methodological framework that aims to reignite ecological processes, rather than delivering a single design. It proposes a nature-based identity for the public realm, with the intent that it can later be extended and applied elsewhere in Montreal as a flexible tool adaptable to different urban contexts.
While the master plan provides a general roadmap and a phasing strategy, implementation has required flexibility. Due to anticipated impacts from the hydro infrastructure upgrades, rather than proceeding with the phased implementation outlined in the master plan, the Borough has deferred major interventions and has instead concentrated on applying the master plan’s strategies in alternate locations. While implementation thus far has not directly aligned with the proposed framework, enhanced ecological connectivity and pollinator and avian activity along the corridor have been documented.
