A recent return visit confirms what restoration practitioners know well: when barriers are removed, rivers heal. Today, the Paulins Kill flows freely through the former Paulina Lake Dam site, reconnecting habitats that had been fragmented for generations. The Paulina Lake Dam stood for nearly 130 years in Blairstown Township, Warren County, NJ. Constructed in the late 1800s to generate hydropower, it had long outlived its original purpose. Like many aging dams across the country, it remained in place despite no longer serving a critical function, while continuing to disrupt river processes and pose growing safety risks. [caption id="attachment_19094" align="aligncenter" width="800"] Paulina Lake Dam aerial view prior to removal. Photo by Jim Wright/TNC/LightHawk[/caption] As reported in CentralJersey.com’s recent feature “The fall of dams and rise of rivers,” the majority of New Jersey’s approximately 1,700 regulated dams were built in the 19th and early 20th centuries to power mills that no longer exist. Fewer than a dozen still serve an essential purpose today. Many persist due to nostalgia, misunderstanding, or uncertainty around removal—despite blocking fish passage, trapping sediment, warming water temperatures, exacerbating flooding, and increasing the risk of failure. The removal of Paulina Lake Dam was led by The Nature Conservancy (TNC) in partnership with Blairstown Township, New Jersey Department of Environmental Protection, U.S. Fish and Wildlife Service, Riverlogic–Renova Joint Venture, and Princeton Hydro. The Office of Natural Resources Revenue awarded a grant to TNC to fund a substantial portion of the removal through the Paulins Kill and Pequest Watershed Natural Resource Restoration Grant Program. The project advanced through carefully sequenced phases, beginning with controlled notching in late 2023, followed by full demolition and sediment management in 2024, and transitioning into final adaptive management and habitat enhancement in 2025. What the River is Showing Us Now The ecological response has been swift and visible. With the dam removed, more than 7.6 miles of mainstem and tributary habitat have been reconnected at the Paulina Lake site alone. The removal of the Paulina Lake Dam represents one important element of a longer-term, watershed-scale restoration initiative launched in 2013 to restore connectivity and ecological function along the Paulins Kill River. As the downstream most dam on the river, its removal builds upon earlier restoration milestones achieved through the removal of four dams: the Columbia Lake Main and Remnant Dams in 2019, the County Line Dam in 2021, and now the Paulina Lake Dam, progressively reconnecting approximately 45 miles of mainstem and tributary habitat. Since 2016, The Nature Conservancy has also implemented a 10-year Measures and Monitoring Program to track ecological response and conservation outcomes, providing clear evidence that coordinated, science-based restoration can support a healthier, more resilient river system. The river channel is actively stabilizing, riffle and run sequences are re-forming, and previously inundated areas are beginning to revegetate. Cooler water temperatures and the restoration of sediment transport processes are enabling the Paulins Kill to function more consistently with a cold, free‑flowing, coarse‑substrate stream system. This series of aerial drone photos was captured during a site visit in November 2025: [gallery link="none" size="medium" ids="19109,19110,19111"] This recovery is already benefiting aquatic life. As Beth Styler Barry, Director of Freshwater Programs for The Nature Conservancy in New Jersey, noted in the CentralJersey.com article, “We’re already seeing American shad above the dams that were removed. We’re seeing sea lamprey and American eel. It used to be that only the biggest eels could make it upstream. Now we’re seeing all age classes.” By reconnecting upstream and downstream populations that had been isolated for generations, the project has also restored connectivity for rare freshwater mussels, including the endangered dwarf wedgemussel (Alasmidonta heterodon) and triangle floater (Alasmidonta undulata). “All of the organisms in a river like the Paulins Kill evolved to live in a cool, flowing, rocky-bottom stream,” Styler Barry told CentralJersey.com. “When you restore flow, the river begins to heal itself.” Watch the Project from Start to Finish A newly released project video captures this transformation in a way that still images and written updates cannot. Drawing on aerial footage collected by The Nature Conservancy’s Volunteer Drone Team prior to demolition and by Princeton Hydro throughout and after construction, the video documents the full arc of the Paulina Lake Dam removal from initial notching through full demolition and into the restored conditions visible today. The footage provides a comprehensive look at dam removal in practice, illustrating how careful sequencing, sediment management, and adaptive design allow rivers to recover rapidly once barriers are removed. Click below to watch the full project video and see the transformation unfold: [embed]https://www.youtube.com/watch?v=T6dQRRU5DCE[/embed] Beyond ecological gains, the removal of Paulina Lake Dam has significantly improved public safety and community resilience. In CentralJersey.com, Geoffrey M. Goll, PE, President of Princeton Hydro, emphasized the long-term risks associated with aging dams. “If you don’t take care of them, they’ll come out on their own—and that’s a much bigger problem. Once dams are properly removed, people start to see the value of a free-flowing river.” Many dams were never designed to withstand today’s hydrologic conditions. With climate change driving more frequent and intense rainfall events, proactive removal reduces flood risk, eliminates inspection and maintenance liabilities, and allows rivers to function as more resilient, self-sustaining systems. At the Paulina Lake site, removal has also improved recreational access and restored a more natural landscape for the community. Looking Ahead While the Paulins Kill now flows freely through the former Paulina Lake Dam site, final project phases focus on adaptive management, targeted bank stabilization, habitat feature enhancement, and native tree planting to support long term ecological resilience. As the river continues to adjust and evolve, the Paulina Lake Dam site stands as a clear example of what is possible when outdated infrastructure is thoughtfully removed and natural systems are given the opportunity to recover.

At the same time, these landscapes provide critical habitat and natural defenses that protect people, ecosystems and myriad wildlife. Coastal ecological restoration restores natural systems and strengthens future resilience to climate impacts. Earlier this month, our team joined the New Jersey Coastal Resilience Collaborative (NJCRC) for its Coastal Ecological Restoration Technical Workshop, a full-day, in-person event held at the Rutgers EcoComplex in Bordentown, NJ. The workshop convened coastal stakeholders, researchers, practitioners, and managers to share knowledge and explore the latest science advancing coastal ecological restoration.

More About Coastal Restoration Coastal ecological restoration involves the rehabilitation and creation of coastal ecosystems, like wetlands, reefs, and shorelines, with the goal of restoring the natural processes and functions. These efforts provide long-term protection from erosion, create habitat for fish and wildlife, and build community resilience against flooding and storm surge. At Princeton Hydro, we understand the impacts of climate change, including sea level rise, and use tools such as vulnerability assessments to inform our restoration designs. Our team specializes in designing and implementing living shorelines and habitat restoration projects. We combine field data, empirical approaches, ecological and geomorphic understanding, hydrologic and hydraulic modeling, and state-of-the-art computer programming technology to develop our designs. Our nature-based solutions deliver lasting ecological and community benefits. A prime example of this work is the Spring Creek North Ecosystem Restoration project, located in Brooklyn and Queens, NY. Once part of the expansive Jamaica Bay wetland system, Spring Creek's salt marshes were heavily degraded over the last century. Princeton Hydro was contracted by the U.S. Army Corps of Engineers, New York District to lead the design and engineering for this restoration effort. Construction efforts began in early October 2025. Once completed, the project will restore approximately 43 acres of habitat within a 67-acre footprint, including low and high marsh, scrub shrub wetland, and maritime upland. Efforts also aim to improve water quality, increase biodiversity, and strengthen the overall Jamaica Bay ecosystem. Key restoration activities include:

We are thrilled to announce that Warrington Township received the prestigious 2025 Pennsylvania Governor's Award for Environmental Excellence for the transformative ecological uplift initiative at Lion’s Pride Park—a collaborative restoration effort for which Princeton Hydro served as the design, regulatory, and construction administration lead.
Each year, the Governor’s Environmental Excellence Awards, administered by the Pennsylvania Department of Environmental Protection (PADEP) under the leadership of Governor Josh Shapiro, recognize innovative projects that demonstrate a strong commitment to environmental protection, climate resilience, community engagement, and sustainability. Winning projects are selected for their measurable environmental outcomes, creative approaches to conservation, and the strength of their partnerships. For 2025, only 19 projects across the entire Commonwealth were selected for this honor, highlighting the exceptional impact and innovation of each initiative.
In a press release, PADEP Acting Secretary Jessica Shirley said, “The Environmental Excellence honorees embody the innovative thinking needed to protect our environment and shape a more sustainable future here in Pennsylvania. Together, we will spur the next generation of environmental stewards. These projects showcase our ability to work collaboratively to preserve and protect Pennsylvania’s natural resources.”
The Lion’s Pride Park Ecological Restoration Project stood out as a model of creative collaboration, forward-thinking design, and community engagement. This ambitious effort transformed an overgrown, flood-prone pond into a thriving, accessible wetland mosaic that now supports native biodiversity, mitigates stormwater impacts, and provides a wide range of environmental education and outdoor recreation opportunities.
Spanning 47 acres, Lion’s Pride Park serves as a vital green space for the Warrington Township community. However, the pond at the center of the park was affected by invasive species overgrowth, chronic flooding, and declining water quality.
To address these issues, Warrington Township and Warrington Environmental Advisory Council partnered with Princeton Hydro to develop and implement a comprehensive restoration strategy. Beginning in 2020, the team conducted detailed site investigations, including bathymetric surveys, sediment analysis, and wetland delineations to understand the site’s specific challenges and ecological potential.
The work culminated in the design and regulatory coordination of a restoration plan focused on converting the pond area into a biodiverse emergent wetland system. Some of the key project elements include:
Throughout the process, Princeton Hydro led the permitting and compliance efforts, securing approvals from PADEP, U.S. Army Corps of Engineers (USACE), and Bucks County Conservation District to ensure that the project met both ecological and regulatory standards.
Now, the revitalized wetland serves as a habitat haven for birds, pollinators, and native plant species; reduces nonpoint source pollutants discharged to downstream waters; and provides accessible pathways and observation platforms so all community members may learn from and enjoy this restored landscape.

The removal of Paulina Lake Dam marks a significant step in restoring the Paulins Kill River. With the spillway demolished, dredging completed, and the trail bridge stabilized as of October 2024, the transformation has been remarkable. A new project video now captures this rapid evolution and celebrates the progress made.
We invite you to watch the new video documenting the removal process for the Paulina Lake Dam. The video's captivating aerial footage, taken by The Nature Conservancy (TNC) Volunteer Drone Team before demolition and by Princeton Hydro throughout and after the removal process, showcases the dramatic transformation of the site. The video walks viewers through each removal phase, from initial notching to full demolition, while highlighting what’s next in the ongoing Paulins Kill River restoration effort.
The removal of Paulina Lake Dam is part of a broader effort to restore the Paulins Kill River and its ecosystem. Since 2019, four dam removals, including Columbia Lake’s remnant and main dams (2019), County Line Dam (2022), and Paulina Lake Dam (2024), have reconnected 45 miles of river habitat, allowing native species like brook trout and migratory fish to thrive.
Beyond enhancing aquatic and terrestrial connectivity, the dam’s removal mitigates safety hazards, improves water quality, and expands recreational opportunities for the community. It also contributes to ongoing wetland and riparian zone restoration, including the reforestation of the floodplain and protection of critical habitats.
While the dam is gone, restoration efforts are not quite over. In early Spring, the project team will initiate the third and final project phase by visiting the site to assess and plan for adaptive management work, which will commence in July 2025. During this final push, the project team will enhance habitat features, stabilize riverbanks in select locations, and plant native trees, ensuring a thriving ecosystem for years to come. Stay tuned for more updates as we continue to witness the transformation of the Paulins Kill.
Rivers are the lifeblood of ecosystems, weaving through landscapes to connect habitats, sustain biodiversity, and provide vital resources to communities. Yet, rivers around the world are disrupted by outdated dams, weirs, culverts, and other blockages that fragment habitats, block fish migration, and degrade ecological health. The consequences are far-reaching, threatening not only ecosystems but also the communities that depend on healthy rivers.
Research by the European Open Rivers Programme has highlighted both the urgent need for action and the immense potential of dam removal to restore ecosystems, improve biodiversity, and revive natural river connectivity.
Since 2022, Princeton Hydro President and Principal Geoffrey M. Goll, PE, an expert in water resources engineering, has been collaborating with organizations in Portugal to advance shared goals of river restoration and ecosystem revitalization. In October 2024, Mr. Goll traveled to Portugal, where he met with the organizations driving forward the country’s ecosystem restoration efforts and visited the sites of three key projects he has, or is currently collaborating on.
This blog explores those restoration efforts, highlighting how they address the challenges of river fragmentation while establishing a blueprint for future restoration efforts.
One of the most significant examples of these collaborative restoration efforts is the groundbreaking Galaxes Weir Removal project, which set the stage for future initiatives by addressing river fragmentation on Portugal’s Odeleite River.
Galaxes Weir Removal project in Portugal's Algarve Region marked the country’s first civil removal of an obsolete river barrier to benefit migratory fish species. Associação Natureza Portugal in association with World Wildlife Fund Portugal (ANP/WWF), a non-profit NGO dedicated to the conservation of nature and the protection of the planet, reached out to Mr. Goll and Ms. Lisa Hollingsworth-Segedy of American Rivers, to undertake this pioneering effort.
Completed in March 2023, the removal of the 2-meter-high Galaxes Weir restored 7.7 kilometers of river connectivity, aiding in the preservation of critical fish species such as the Spanish minnowcarp (Anaecypris hispanica) and the critically endangered European eel (Anguilla anguilla). By improving river flow and ecological conditions, the project also bolstered economically vital fisheries, enhanced recreational opportunities, and supported local tourism, establishing a model for future restoration initiatives. Funding for the Galaxes Weir removal was provided by the European Open Rivers Programme (EORP), a grant-giving organization dedicated to restoring European rivers. The international partnership that brought Mr. Goll and Ms. Hollingsworh-Segedy into the fold was facilitated by connections made through the World Fish Migration Foundation. He and Ms. Hollingsworth-Segedy were asked to provide guidance on the de-construction of this concrete structure.
The success of the Galaxes Weir Removal project highlights the importance of both engineering knowledge and techniques, as well as community engagement. By involving local communities throughout the process, the project fostered a sense of shared responsibility and ensured that the ecological and cultural value of the river was preserved. It also underscored the benefits of dam removal as a swift and effective strategy to enhance biodiversity and promote sustainable river management.
Building on the success of the Galaxes Weir removal, the ANP/WWF team expanded its efforts to Santarém, Portugal, northeast of Lisbon, on the Perofilho Stream, a tributary of the Tejo River. The Perofilho Weir, a 2-meter-high concrete barrier, fragmented habitats and disrupted the natural flow of the stream. The National Authority for Nature and Forests Conservation (ICNF) identified the Galaxes Weir as one of the obsolete barriers to be removed to improve fish and overall biodiversity in the area and restore fluvial connectivity.
This restoration project, initiated in 2023, was led by ANP/WWF in collaboration with SOS Animal (weir owner) and the Santarém Municipal Council (local government). Mr. Goll was invited to design the removal of the concrete weir, including innovative solutions such as the use of live timber crib walls for stream bank stabilization. He also provided consultation to the onsite construction manager during the removal process and conducted a final site walkthrough following construction, offering recommendations to ensure long-term success.
The Perofilho Weir removal, completed in October 2024, restored 2.2 kilometers of the Perofilho Stream—nearly half its total length—reconnecting it with the Tejo River. This comprehensive restoration project addressed sediment management, habitat rehabilitation, and flood risk reduction, resulting in significant improvements to water quality and ecological health. Key species benefiting from these efforts include the Eurasian otter (Lutra lutra) and the Iberian painted frog (Discoglossus galganoi). Notably, it also enabled the first research into fish species inhabiting the stream.
This milestone project not only revitalized a critical aquatic ecosystem, it also established a blueprint for future river restoration efforts in Portugal and beyond.
During Mr. Goll’s visit to Portugal in October 2024, he toured the Perofilho Weir removal site alongside Maria João Costa, Water Coordinator of ANP/WWF. Together, they participated in a live video event hosted by the World Fish Migration Foundation, celebrating the project’s success. Broadcasted on the Dam Removal Europe YouTube channel, the event highlighted the restoration effort’s impact on biodiversity and river connectivity. If you missed the live broadcast, the recording is available online. Watch now:
The Oeiras River in western Algarve winds through rural landscapes, agricultural zones, and small towns before merging with the Arade River. This intermittent Mediterranean stream supports native and endangered species and serves as a habitat for some of Portugal’s most iconic mammals.
Recognizing the river’s ecological significance, the ICNF identified it as a high-priority conservation area with potential for impactful restoration. In collaboration with the company Somincor, ICNF contracted ANP/WWF to evaluate the removal of nine barriers along the river, beginning with the upstream Horta Fialho Weir.
To complete the proposed work, ANP/WWF is undertaking several activities, including feasibility assessments, local community and stakeholder engagement, and public environmental education. ANP/WWF engaged Princeton Hydro to prepare the design and specifications for the Horta Fialho Weir removal and develop concept designs for the eight (8) additional barriers.
In October 2024, Mr. Goll spent a week in the field alongside ANP/WWF, surveying the Oeiras River and its tributaries, documenting blockages and ecosystem conditions, meeting with local dam owners and community members, and gathering field measurements to inform the designs and specifications.
The removal of the Horta Fialho Weir will reconnect 2.34 kilometers of the river and set the stage for removing the eight additional barriers, which would ultimately restore 143.4 kilometers of river connectivity. This ambitious initiative is expected to significantly enhance the river’s ecological health and improve habitats for native and endangered species, including freshwater mussels (Unio tumidiformis, Anodonta anatina, Unio delphinus), and their host fish (Squalius spp.), the migratory European eel (Anguilla anguilla), the Iberian lynx (Lynx pardinus), and the Eurasian otter (Lutra lutra).
Beyond ecological benefits, the project offers a unique opportunity to raise awareness about the advantages of dam removal and the critical importance of biodiversity conservation across Portugal. The European Open Rivers Programme is funding this landmark restoration effort.
Portugal’s ecosystem restoration projects illustrate the impact of international collaboration and knowledge exchange. By removing barriers, reconnecting habitats, and revitalizing ecosystems, these efforts are paving the way for a healthier future for rivers and the communities that depend on them. Through continued partnerships and mutual support, the journey toward sustainable environmental stewardship remains hopeful and promising.
Building on the success of these initiatives, Mr. Goll and the Princeton Hydro team look forward to continuing their work in Portugal and beyond, offering technical expertise in ecosystem restoration and barrier removal to support similar efforts around the world.
This work would not be possible without the dedication of ANP/WWF, the European Open Rivers Programme, the Dam Removal Europe team, The National Authority for Nature and Forests Conservation, Herman Wanningen, and all the local landowners who were committed to the restoration of the Oeiras River. Their commitment to river restoration and biodiversity conservation serves as an inspiration, demonstrating the transformative power of collaboration and shared vision.

The South Cape May Meadows Preserve, owned and managed by The Nature Conservancy (TNC), is a jewel among New Jersey's protected landscapes. Spanning over 200 acres adjacent to Cape May State Park, the preserve is celebrated for its diverse habitats, including beaches, dunes, freshwater wetlands, and fields. As a crucial stopover along the Atlantic Flyway, it offers refuge to rare and endangered shorebirds as well as native and migratory birds, making it a globally renowned paradise for birders. It also supports a wide variety of terrestrial species year-round.
The Preserve also has a variety of features aimed at enhancing visitor experience, promoting sustainability, and supporting its diverse wildlife. These features include a welcome shed with a green roof, a rain garden, purple martin houses, a raised wildlife viewing platform, an osprey platform with a streaming camera, benches, interpretive signs, and an 80-foot bird blind.
With its rich biodiversity, scenic beauty and unique features, the South Cape May Meadows Preserve is a site of high public interest and use, attracting approximately 90,000 visitors each year. To accommodate the high level of public interest and improve accessibility, TNC contracted Princeton Hydro to upgrade the existing path network to make it more physically accessible and to create new pathways that open up previously unreachable areas of the Preserve.
Given that much of the site is composed of freshwater wetlands, creating accessible pathways without disturbing these sensitive areas presented a unique challenge that required innovative solutions. To address this, the centerpiece of the project was the construction of an elevated boardwalk trail in the western area of the preserve. Slated for completion in September 2024, the new boardwalk will add 2,675 linear feet of elevated walking paths throughout the preserve, along with a 480-square-foot elevated viewing platform. The boardwalk will wind through previously inaccessible wetland areas and is designed to comply with ADA standards, ensuring that visitors of all abilities can explore and enjoy the preserve's unique maritime landscape.
Led by TNC, the Princeton Hydro team was responsible for designing, permitting, and overseeing construction for the project, with Renova serving as the primary construction partner. The images below are renderings and a mapped layout of the project site created by Landscape Architect Cory Speroff, PLA, ASLA, CBLP of Princeton Hydro, the lead project designer and project manager:
To minimize environmental impact during construction, the boardwalk is being installed using a top-down construction method. This approach required finding a product that could meet all design requirements while supporting the necessary equipment for construction from above. The project team selected GreenWalk™, a proprietary structure system manufactured by IDEAL Foundation Systems. GreenWalk™ is a highly engineered, modular, zero-maintenance boardwalk system that meets all of the project criteria while ensuring minimal disturbance to the wetland.
This video provides a behind-the-scenes look at the boardwalk installation process and the intricate work involved in bringing this accessible pathway to life. Watch now to see how we're making nature more accessible for everyone:
In addition to the boardwalk, the Princeton Hydro team designed and permitted several site improvements to enhance accessibility and visitor experience:
Existing trail surface types were assessed for sturdiness, and cost-effective measures were implemented to enhance accessibility. This included leveling the existing gravel and sandy portions of the Main and East trails and replacing them with a firmer, more stable surface.
Equipped with safety railing, handrails, seated observation areas, and educational signs in both braille and English print, the boardwalk is designed to provide support for people with accessibility considerations.
The existing parking lot was upgraded to include formal ADA spaces. One-third of the original stone parking lot was converted to concrete to improve accessibility.
These efforts ensure that the South Cape May Meadows Preserve remains an inclusive and ecologically sensitive destination, allowing all visitors to fully appreciate the natural beauty and biodiversity of this unique maritime landscape.
Speroff emphasized that the boardwalk is more than just a pathway through nature; it symbolizes a collective commitment to protecting and celebrating the environment: “It stands as a reminder that we can create spaces that are both beautiful and functional, without compromising the health of our planet. By choosing sustainable materials and practices, we have set a standard for future projects in our community and beyond. Moreover, this boardwalk represents our pledge to inclusivity, going above and beyond the minimum standards for ADA compliance. We created a space where everyone, regardless of physical abilities, can enjoy the beauty of our natural surroundings—a place where families can come together, individuals can find solitude, and nature can be experienced by all.”
On Sunday, August 4, TNC hosted a ribbon-cutting ceremony at the South Cape May Meadows Preserve to unveil the new boardwalk trail and site enhancements. The event highlighted the significant strides made in increasing the preserve’s accessibility and offered attendees a preview of the new features, including four metal plaques with tactile elements and braille, showcasing nature themes like the life cycle of a butterfly and frog, turtle shells, and dragonflies.
Speeches were given by Barbara Brummer, State Director of The Nature Conservancy in New Jersey; Paulo Rodriguez Heyman, President of Renova; Mark Gallagher, Vice President of Princeton Hydro; and both the father and grandmother of Julian Tao Knipper. The Knipper family generously donated to the project in memory of Julian, who dearly loved Cape May and tragically passed away at the age of three. The project also honored Pat and Clay Sutton, esteemed educators, authors, naturalists, photographers, lecturers, nature tour leaders, and long-time champions for the protection of Cape May’s rich biodiversity. The new trail was officially dedicated to Julian, Pat and Clay.
Speroff expressed deep appreciation for the donors, stating, “The belief in this project and the willingness to invest in this vision made it possible to create a space that is accessible to all and harmonious with our natural surroundings. These contributions are not just financial; they are investments in the future of the Cape May community and our planet.”
It is essential to also acknowledge the invaluable contributions of those who made this project possible, creating a space where people of all abilities can enjoy nature, reflect, and find peace. Special thanks go to The Nature Conservancy, particularly Barbara Brummer, Eric Olsen, Damon Noe, Elliot Nagele, and the TNC project staff. The Renova Team's hard work and dedication were instrumental in bringing the one-of-a-kind boardwalk to life. Additionally, the design team, including IDEAL Foundation Systems, Bedford, L2A, and JBCI, played a crucial role in the project’s success. And, members of the Princeton Hydro team, especially Cory Speroff, PLA, ASLA, CBLP; Geoffrey M. Goll, P.E.; Ryan Eno, EIT; Ivy Babson; and Casey Pantaleo, P.E.
The Nature Conservancy and Princeton Hydro have a storied history of working on impactful projects together, from removing obsolete dams and opening up miles of river for fish passage to eradicating invasive species right here on this property. A few years ago, we designed the removal of Columbia Lake Dam, which reconnected 20 miles of stream, with American Shad returning to their native spawning grounds upstream just months after it was removed. And now, as this South Cape May Meadows Preserve project nears completion, we celebrate a project that offers everyone the chance to experience its natural beauty and biodiversity. This collaboration between Princeton Hydro and TNC underscores the importance of creating inclusive spaces that honor and protect our natural world.
Within the next few weeks, stay tuned for more updates and photos as we near completion on this exciting project, ensuring that the South Cape May Meadows Preserve remains a cherished destination for all who visit.
The New Jersey Department of Environmental Protection (NJDEP), U.S. Army Corps of Engineers (USACE), project partners, and elected officials broke ground on the interior cleanup of Liberty State Park in Jersey City (Phase 1A), marking a significant milestone in the history of New Jersey’s most visited state park.
During the groundbreaking ceremony, participants heard presentations from Commissioner of Environmental Protection Shawn M. LaTourette, USACE New York District Commander Colonel Alex Young, Assemblywoman Angela McKnight, and Assemblyman William B. Sampson IV.
As quoted in the press release distributed by the Murphy Administration, Commissioner LaTourette said, “Today’s groundbreaking is a critical step toward building a future at Liberty State Park that brings people and communities together to enjoy the environment we all share. Through the cleanup and restoration of nearly 235 acres, we will reckon with the industrial pollution of our past and from it, create a world-class outdoor urban environment that will be enjoyed by many future generations.” Click here to read the full press release.
A long history of industrial contamination (also called legacy pollution) has left 235 acres of Liberty State Park fenced-off and inaccessible to the public for decades. The groundbreaking ceremony marks the official start of Phase 1A of the clean up and restoration project.
Princeton Hydro was contracted by USACE New York District in partnership with the NJDEP Office of Natural Resource Restoration to design a resilient coastal ecosystem within 235 acres of this highly urbanized setting that provides both ecological and social benefits. This includes the restoration of over 80 acres of tidal and non-tidal wetlands and creation of several thousands of feet of intertidal shoreline and shallow water habitat hydrologically connected to the Upper New York Bay. When constructed, this will be one of the largest ecosystem habitat restoration projects in New Jersey.
In July 2021, a significant transformation began on Bushkill Creek in Pennsylvania. The removal of Crayola Dam, which was was officially completed on September 29, 2022, marked the start of a journey to restore this beloved waterway to its natural state.
Now, in September 2023, as we commemorate the one-year anniversary of this remarkable undertaking, we reflect on the importance of preserving high-quality, cold-water fisheries in urban environments and eagerly anticipate the continued restoration work on Bushkill Creek in the years ahead.
Bushkill Creek originates at the base of Blue Mountain in Bushkill Township and meanders for 22 miles until it joins the Delaware River. This limestone stream flows through a diverse landscape, encompassing agricultural and suburban areas, as well as the city of Easton. It is not only a vital water resource but also a sanctuary for a thriving population of wild brown trout. Designated as a "high quality, cold-water fishery," Bushkill Creek holds a special place in the hearts of anglers and the surrounding community.
The journey to restore Bushkill Creek evolved over a decade of collaboration between Princeton Hydro and the Wildlands Conservancy. This partnership has focused on multiple dam removal projects in the Lehigh River Valley, each aimed at reestablishing aquatic habitats, enhancing recreational opportunities, and revitalizing economically stressed urban communities.
In particular, Princeton Hydro took the lead in designing and permitting the removal of eight consecutive barriers on Jordan Creek and two low-head dams on Little Lehigh Creek. These projects resulted in the reconnection of miles of river, an improvement in aquatic habitats, and enhanced recreational fishing opportunities in Allentown, PA.
The success of these barrier removals set the stage for a more ambitious project in 2018, as Princeton Hydro joined forces with the Wildlands Conservancy to tackle four privately and publicly owned dams, including three consecutive dams on Bushkill Creek in Easton, PA. These projects became a blueprint for future dam removals throughout the Delaware and Lehigh Valley Watersheds, serving as a model for landowners and municipalities.
The combined barrier removals were part of a larger watershed-wide effort to enhance aquatic connectivity, fisheries, and wildlife habitats. These initiatives restored fish passage, reduced nonpoint source pollution, improved water quality, and reinstated groundwater recharge capacity. They also played a crucial role in stabilizing and restoring the stream's channels and banks.
The successful execution of these dam removal projects was no small feat. Princeton Hydro's comprehensive approach included site investigations, field surveys, sediment analysis, hydraulic assessments, regulatory coordination, community engagement, design planning, permit applications, cost estimates, and construction oversight. RiverLogic Solutions LLC, the construction contractor selected for the Dam #4 removal, completed the project in line with design plans and permit waiver requirements.
The result was the official removal of the Crayola Dam, also known as Dam #4, marking a significant milestone in the restoration of Bushkill Creek.
As we celebrate the one-year anniversary of the Dam #4 removal, we also look ahead to the next phases of this restoration journey. The demolition and removal of Dam #1 commenced on July 7, 2023 and was completed in August. Dam #3 is scheduled for demolition and removal later this year. And, the fourth barrier, Dam #2, is scheduled for removal in the summer of 2024. Additionally, there is a fifth dam on Bushkill Creek that Wildlands Conservancy is pursuing for removal. Stay tuned for more info!
As we move forward, we are excited about the future of Bushkill Creek and the positive impact its restoration will continue to have on both the surrounding community and beyond.
Princeton Hydro has designed, permitted, and/or overseen the removal of 80+ small and large dams in the Northeast. For over a decade, Princeton Hydro has partnered with Wildlands Conservancy to remove dams in the Lehigh River Valley.

Exciting changes have unfolded at Kol Emet, a Reconstructionist Congregation in Yardley, Bucks County, Pennsylvania. The campus’ exterior lands have undergone a remarkable transformation, blossoming into an enchanting and peaceful place for community member gatherings, and a wildflower meadow.
Princeton Hydro partnered with Congregation Kol Emet to design and implement the synagogue's 10-acre campus transformation. The Princeton Hydro team provided green infrastructure engineering, landscape architecture, and construction services aimed at enhancing the usability and welcoming atmosphere of the synagogue, and creating a sustainable outdoor solution in the event of future pandemics, and a place to connect with the natural environment that surrounds the property. The design provides a net positive impact by reducing flooding in the community and improves water quality by augmenting stormwater management and biodiversity throughout the property.
"Our vision surpassed mere construction of a gathering space," said Geoffrey M. Goll P.E., President of Princeton Hydro, a congregant of Kol Emet, Executive Board Member, and point person for the project. "We wanted to create a harmonious union between the synagogue campus and the surrounding preserved woodlands, cultivating a serene haven where congregants can unite, celebrate, and worship, while also enhancing the ecological functionality and biodiversity of the landscape. This was a realization of the vision of the Founders of Kol Emet and the labor and financial support of many members of the Board, past and present, and a generous donation by a longtime supporter of the community. The outdoor sanctuary was named in honor and memory of a founding member and former President, Geri Shatz, who was a staunch supporter of the Jewish community and advocate for the mission of Kol Emet. She lived the ideals of community and contribution. I am proud of the extraordinary transformation that’s been achieved."
The Kol Emet Reconstructionist Congregation, is a 501(c)3 religious organization, founded in 1984. While a center of worship for its members, it is much more than that. Kol Emet is a community of people who care about improving the world around them through social action and environmental protection.
The sentiment of "Tikkun Olam" is embodied by Kol Emet and the committee that spearheaded the project, working directly with the Princeton Hydro team to bring the project goals to fruition. The modern interpretation of the Hebrew phrase “Tikkun Olam,” is “action intended to repair and improve the world.” The campus restoration project brings the concept of “Tikkun Olam” to life.
Princeton Hydro Landscape Architect Cory Speroff, PLA, ASLA, CBLP is the project’s lead designer. The project included landscape design and planting that incorporates native and sustainable trees and shrubs; significant upgrades to the existing stormwater management basin, including the conversion of low-flow channels, impervious surfaces, and turf-covered areas to native grassland and wildflower habitat; and the development of the “Geri Shatz Outdoor Contemplative Space."
Cory’s design inspiration for the Geri Shatz Outdoor Contemplative Space is modeled after the Hebrew term “etz chaim” or “Tree of Life.” In Judaism, the Tree of Life has a number of meanings, both literal and figurative. In the Kabbalah, the Tree of Life represents the connection between heaven and earth, wisdom and knowledge, and the interconnectedness of all living things. It is visually represented as a diagram that looks much like a tree with 10 nodes and 22 lines. Cory’s design for the community space uses strategically placed trees to mimic the Tree of Life and aims to promote community connection and a connection to the surrounding natural landscape.
The contemplative space consists of a bimah, seating to accommodate at least 80 people, and a beautiful array of native trees and flowering shrubs, including black gum, silver birch, and Virginia sweetspire.
Cory’s design for the land surrounding the contemplative space improves flood resilience; controls stormwater runoff volume and promotes groundwater recharge; boosts safety features of the campus; and enhances habitat for pollinators, native plants, and other important species. The wildflower meadow was seeded with a variety of native plants, including purple love grass, common milkweed, wild bergamot, and blue wild indigo.
“During the height of the COVID-19 pandemic, it felt like the only way to see our loved ones was to be outside, and during these backyard and front porch gatherings many people re-discovered their love for the outdoors,” said Cory. “In talking with the Committee, there was a desire to create an outdoor sanctuary where the congregation could gather and continue that re-discovery. I believe that through the careful consideration of symbolic elements and thoughtful design choices, we’ve created a space that can inspire introspection, connection, and a sense of harmony with both nature and faith.”
Funding for the project came from the Congregation Kol Emet’s “Our Heart. Our Home” capital campaign, a $750,000 campaign focused on upgrading four key aspects of the synagogue: social hall, HVAC upgrades, indoor sanctuary, outside school, and the new outdoor sanctuary. The outdoor sanctuary and ecological uplift to the 10-acre campus is a primary piece of the campaign and was made possible by the generous donations of several Kol Emet members.
Stan Shatz bestowed a bounteous donation in memory of Geri Shatz, which made possible the creation of the “Geri Shatz Outdoor Contemplative Space.”
The following families also contributed to the funding of the Geri Shatz Outdoor Contemplative Space: Laurel & Kevin Bloch, Barbara & Debra Fogel and Family, Jill & David Gordon, Annie & Ryan Kubanoff and Family, and Teddi & Josh Matisoff and Family.
The Princeton Hydro team is honored to have worked with Kol Emet on this important and inspirational project.
Congregation Kol Emet came together on Sunday, June 4, 2023 for a celebration and ribbon-cutting ceremony to mark the completion of the outdoor sanctuary project. Here are a few photos from the joyous event:

Liberty State Park is located on the west bank of Upper New York Bay and is one of the most visited state parks in the nation with over 5.1 million visitors. Princeton Hydro was contracted by U.S. Army Corps of Engineers (USACE) in partnership with the New Jersey Department of Environmental Protection (NJDEP) Office of Natural Resource Restoration (ONRR) to design a resilient coastal ecosystem within 235 acres of this highly urbanized setting that provides both ecological and social benefits. This includes the restoration of over 80 acres of tidal and non-tidal wetlands and creation of several thousands of feet of intertidal shoreline and shallow water habitat hydrologically connected to the Upper New York Bay. When constructed, this will be one of the largest ecosystem habitat restoration projects in New Jersey.
NJDEP held an open house on May 24, 2023 at Liberty State Park announcing the next steps for the Revitalization Program. During the open house, Environmental Protection Commissioner Shawn M. LaTourette and USACE Colonel Matthew W. Luzzatto shared details of the multi-phase revitalization program for the park.
The public was presented with a video that showcases detailed engineering design renderings and simulates the expected visitor experience. The video was created using renderings by Princeton Hydro's Landscape Architect Cory Speroff PLA, ASLA, CBLP and produced in-house by our Marketing & Communications Department in collaboration with NJDEP ONRR. Watch it now:
Once constructed, this project will expand public access, improve water quality, restore native plant communities, and improve coastal resilience for urban communities who are vulnerable to storm events. The site design includes a trail network for the park interior that will provide access to the newly established habitat zones and views of the Statue of Liberty and New York City skyline. This trail network will enhance pedestrian connectivity between the existing portion of Liberty State Park, Liberty Science Center, Jersey City, and local public transit hubs.
Project partners for the interior restoration design include USACE, NJDEP ONRR, National Oceanic and Atmospheric Administration, U.S. Fish and Wildlife Service, National Fish and Wildlife Foundation, HDR, and Princeton Hydro.
Over the next year, NJDEP will provide the community with updates on revitalization program activities, which will include multiple points of continued public engagement and opportunities for community input to inform further design work. The initial groundbreaking is anticipated to take place in Fall 2023.
