While the New Jersey Department of Environmental Protection (NJDEP) provides baseline regulatory standards, these requirements function only as minimum thresholds. Under New Jersey’s home rule framework and the Municipal Land Use Law (MLUL), municipalities have broad authority to shape development patterns and use zoning, environmental ordinances, and master planning to adopt standards aligned with their community’s environmental constraints and development demands. How municipalities put this authority into practice framed a recent webinar hosted by The Watershed Institute: “Municipal Ordinances: Key to Environmental Protection.” Moderated by Michael Pisauro, Esq., Policy Director for The Watershed Institute, the webinar brought together three experienced practitioners to explore how municipalities can leverage local ordinances to strengthen environmental protection and community resilience:

How municipalities put this authority into practice framed a recent webinar hosted by The Watershed Institute: “Municipal Ordinances: Key to Environmental Protection.”
Moderated by Michael Pisauro, Esq., Policy Director for The Watershed Institute, the webinar brought together three experienced practitioners to explore how municipalities can leverage local ordinances to strengthen environmental protection and community resilience:
Each presenter approached the issue from a different, complementary lens: science, land use law, and regulatory practice.
Mark began the webinar with an overview of New Jersey’s natural green infrastructure (forests, floodplains, riparian corridors, wetlands, and meadows) and its role in supporting stormwater management. Engineered systems are most effective when the surrounding natural landscapes can absorb, slow, and filter runoff. He stressed that municipalities shape the fate of these natural systems through their zoning and development decisions, making local ordinances essential to watershed health.
Mark examined how decades of land alteration, including stream channelization and straightening, impervious surface expansion, and floodplain encroachment, have dramatically changed stream systems across the state. As runoff volume increases, so does the frequency and duration of bankfull flows, which widen channels, erode banks, and transport sediment. A key indicator of watershed imbalance is floodplain disconnection: in healthy systems, streams access their floodplains during frequent storm events, dissipating energy and reducing downstream impacts. In many developed watersheds, streams remain confined within incised channels except during major storms, worsening erosion and downstream flooding.
Mark directly connected these environmental realities to municipal decision-making. Municipal ordinances play a critical role in maintaining and restoring the natural systems that support stormwater management, water quality, and community resilience. Municipalities can shape new development and use redevelopment projects as opportunities to repair historic environmental damage.
He highlighted municipal tools that strengthen watershed function, including well-crafted stream corridor ordinances, updated Environmental Resource Inventories (ERIs), master plan policies that prioritize open space preservation, and watershed improvement strategies that integrate ecological restoration with engineered BMPs.
Michele centered her presentation on a key message: the legal tools are already there for municipalities to guide growth responsibly, but they must be applied proactively and with precision.
She addressed a common assumption heard at planning board hearings: “If it’s zoned for it, it must be appropriate.” That assumption, she explained, is not always grounded in environmental analysis. Zoning districts set permitted uses and density ranges, but often without carefully accounting for wetlands, floodplains, sensitive habit, or limited infrastructure capacity.
For years, municipalities operated under the belief that the MLUL’s uniformity clause required identical development yield across parcels within a zone. However, the New Jersey Supreme Court's decision in "Rumson Estates, Inc v. Mayor Council of Borough of Fair Haven" (2003) clarified that municipalities may calibrate density based on the physical characteristics of a property. Environmentally constrained parcels don't need to support the same development intensity as unconstrained sites.
Michele also emphasized the importance of updating land-use definitions. Outdated definitions can inadvertently allow impacts far beyond what the original ordinance intended. Warehouse standards are a clear example: many were written decades ago and don't account for today's 24/7 high‑cube logistics operations with heavy truck traffic. She noted that timing of these updates is also critical. Under the MLUL’s “time of application” rule, existing zoning is locked-in once an application is filed, meaning municipalities must revise their ordinances before developers submit proposals.
Master plans also play a critical role. A well-designed plan evaluates full build-out potential, accounts for infrastructure and resource limitations, and directs growth away from sensitive areas. She urged municipalities to anticipate emerging high‑impact uses, such as data centers, and set appropriate standards in advance.
Michael G. Sinkevich outlined the legal framework that empowers municipalities to regulate environmental impacts and enforce local standards. He demonstrated how federal law, state regulations, and municipal authority intersect, especially in zoning and stormwater management, to create a strong foundation for local environmental protection.
Municipal authority to adopt environmental protections comes from two main sources: First is the zoning power granted under the MLUL, which allows towns to guide development in ways that protect public health, safety, and welfare. The MLUL also outlines what zoning ordinances may regulate, such as building density. The second source is municipal "police power," which permits towns to adopt environmental regulations, as long as they're consistent with state law, when needed to protect people, property, and general welfare. Together, these authorities give municipalities flexibility to craft and enforce environmental safeguards.
He highlighted tree protection ordinances as a clear example of validated municipal authority: In "New Jersey Shore Builders Association v. Township of Jackson" (2009), the New Jersey Supreme Court upheld Jackson Township’s ordinance that required developers to replace removed trees or pay into a dedicated planting fund, formally recognizing the critical role trees play in stormwater management and climate resilience.
Michael also reviewed MS4 permit requirements, which obligate municipalities to manage stormwater across public and private development. Beyond the permit itself, he emphasized that municipal land use boards have an independent responsibility to ensure compliance with state stormwater rules and cannot simply defer to NJDEP. To support municipalities in meeting these obligations, he highlighted several useful resources, including The Watershed Institute, New Jersey Future, Sustainable Jersey, ANJEC, and NJDEP.
Whether you serve on a governing body, land use board, or environmental commission, or work as an engineer, planner, or attorney, the full webinar offers practical insight into how local ordinances shape environmental outcomes. Community members and neighborhood advocates will also find the discussion clear, accessible, and directly relevant to how development decisions affect their town.

On February 12, Princeton Hydro Senior Wildlife Biologist Mike McGraw, CSE, QAWB, ACE joined Bird Town Pennsylvania for a virtual Zoom workshop titled “A Wholistic Approach to Managing Residential and Park Scale Habitats for Rare and Common Bird Species.” The talk brought together ecological science, practical land‑stewardship guidance, and a powerful call to reimagine how communities support thriving bird populations across Pennsylvania and beyond.
Bird Town PA’s Education Committee hosted the webinar as part of its ongoing effort to connect residents, landowners, and municipal leaders with science‑based strategies that enhance local biodiversity. Their mission, centered on community education, habitat conservation, and sustainable landscaping, aligned seamlessly with the themes Mike explored throughout the presentation.
To help extend the reach of this insightful discussion, we’ve collected highlights from the workshop and invite you to watch the full presentation:
Mike’s presentation provided a comprehensive look at the ecological principles behind bird behavior, the habitat features that sustain both common and rare species, and the steps landowners and municipalities can take to strengthen biodiversity within residential and park‑scale landscapes. He wove together life‑history science, soil and plant ecology, practical stewardship strategies, and community‑based conservation approaches to illustrate how thoughtful land management can meaningfully support bird populations across Pennsylvania.
He emphasized that all wildlife depends on very specific combinations of biotic and abiotic conditions, meaning that changes in habitat structure, vegetation, soils, and climate directly influence which species can persist in a landscape.
To illustrate this, Mike walked attendees through:
By examining real examples of species and their migratory behaviors, Mike demonstrated how the presence (or absence) of certain bird species can serve as a diagnostic indicator of habitat function and ecosystem health, revealing signs of environmental stress, habitat fragmentation, and the impacts of climate change.
Mike outlined the fundamental elements birds need to thrive, including food, water, shelter, mates, and protected nesting or rearing spaces, and demonstrated how providing these through intentional plant selection, structural habitat diversity, and management practices rooted in natural processes results in predictable increases in wildlife use.
He paired these concepts with a practical decision‑making framework for landowners and municipalities, encouraging them to understand soils as living systems, increase plant diversity, and use ecological tools such as USDA zones and native plant lists to guide planning. Mike also highlighted the important role residential and municipal landscapes can play in supporting rare and declining bird species, offering real‑world examples and resources to help translate ecological principles into effective habitat improvements.
Access to nature is a fundamental right, and every community has the power to help shape a healthier ecological future. With this message in mind, Mike outlined a variety of ways residents and municipalities can support bird species of greatest conservation need, including implementing building standards that incorporate bird-safe features, expanding education on responsible pet practices such as keeping cats indoors, ensuring feeding stations remain clean, and adding decals to windows around the home to prevent bird strikes. He emphasized the importance of expanding and enhancing public parks and green spaces, particularly in underserved areas, and supporting programs that foster stronger connections between people and the natural world.

Our team participated in a special community screening of the 4-part docuseries, "Roots So Deep (You Can See the Devil Down There)" at the historic Newtown Theatre in Pennsylvania. As one of the country’s oldest continuously operating theaters, the venue provided a meaningful setting for a film centered on heritage, land stewardship, and community. People throughout the region gathered to explore how regenerative grazing can restore soils, support wildlife, and strengthen the resilience of working farms. The event was co-hosted by Newtown Theatre, Bowman's Hill Wildflower Preserve, and Pinelands Nursery.
"Roots So Deep" follows farmers and researchers across the country as they test adaptive multi-paddock (AMP) grazing and measure its ecological impacts. This method mimics the way bison once roamed the land. The film explores themes of soil health, biodiversity, and the value of collaborative land management. Can AMP grazing can help farmers reduce costs by not buying fertilizer, restore depleted soils, rebuild wildlife habitat, and capture carbon?
At the center of the evening was Princeton Hydro Senior Wildlife Biologist Michael McGraw, CSE, QAWB, and ACE, who appears in the documentary for his work studying breeding bird populations in AMP grazed landscapes. His research examines how breeding bird communities differ between paddocks managed with AMP grazing and those that are continuously grazed. The film emphasizes that when grazing is managed thoughtfully, farmland can support both agricultural productivity and ecological benefits, including healthier wildlife populations.
After the screening, Mike participated in a Q and A session and shared insights from his fieldwork. He discussed how grazing practices shape habitat quality and influence wildlife communities, and he answered a range of questions from attendees who were eager to learn about the ecological implications of AMP systems.
Mike was joined by two regional partners. Fran Chismar from Pinelands Nursery contributed perspectives from the native plant restoration community. Fran also co-hosts the podcast Native Plants, Healthy Planet, which is recognized as a top 20 nature podcast and serves as an important platform for discussions on conservation and ecological stewardship. Santino Lauricello, representing Bowman’s Hill Wildflower Preserve, added context through his expertise in native flora and conservation education. Together, their voices reinforced the collaborative spirit that drives ecological work forward.
As the conversation between Mike, Fran, Santino, and the audience began to take shape, the tone was warm, thoughtful, and deeply engaged. Members of the audience responded to the film’s themes with genuine curiosity, asking questions that reflected a sincere interest in the ecological studies presented throughout the documentary. Their enthusiasm created a sense of shared purpose, highlighting a collective desire to support healthier ecosystems and continue learning from the research behind regenerative grazing.
Even if you weren’t able to join us for the screening, you can still be part of the ongoing conversation. The trio came together on the Native Plants, Healthy Planet Podcast for a special Roots So Deep recap episode, where they explored Mike’s involvement in the project, generational shifts in family‑run agricultural operations, and reflections from the live Q&A at the Newtown Theatre. The podcast provides a meaningful way to revisit the insights from the event and continue exploring the themes of regenerative grazing and ecological restoration. Listen now: Roots So Deep with Mike McGraw and Santino Lauricella
We are grateful to the Newtown Theatre, the event organizers, and the conservation partners who helped bring this screening to life. Gatherings like this illustrate the power of bringing science and storytelling together, creating space for communities to learn, reflect, and connect.
If Roots So Deep resonated with you or sparked your curiosity about regenerative grazing and ecological research, we encourage you to continue exploring the film’s themes, follow upcoming screenings, and stay connected with the conversations it inspires. Your interest and engagement help support the momentum behind this important work. If you're a farmer looking to switch to AMP grazing and want to measure the impact, we'd be happy to talk with you about how to get started. Send us a message.

After more than a century of standing, the Paulina Lake Dam on the Paulins Kill River in Warren County, NJ, was fully removed, marking a transformative milestone for one of New Jersey’s largest tributaries to the Delaware River. Led by The Nature Conservancy New Jersey and funded by NJDEP Division of Fish and Wildlife, this multi-phase project concluded this summer with the third and final phase that included adaptive management work and habitat enhancements to boost biodiversity. We provided engineering design and oversight throughout the effort helping restore natural river flow and improve ecological resilience. On the Farmington River in Connecticut, the Winchell-Smith Dam was fully removed after more than a decade of planning and collaboration. Spearheaded by the Farmington River Watershed Association, this project reconnects 30 miles of critical upstream habitat, improving fish passage for species like American shad, alewife, and American eel. We contributed engineering, design, and project oversight, working alongside partners including Miss Porter’s School, CTDEEP Fisheries, and RiverLogic Solutions. The removal enhances ecological health, fish passage, public safety, and recreational opportunities along one of New England’s most celebrated rivers.
We delivered incredible results for our nonprofit and government partners, securing over $3.2 million in funding to support projects that restore ecosystems, enhance habitats, improve water quality, and implement watershed-based green infrastructure and stormwater BMPs, with grants awarded through the National Fish and Wildlife Foundation’s Delaware Watershed Conservation Fund and Section 319(h) of the federal Clean Water Act, administered by NJDEP’s Watershed and Land Management Program. We assisted the Borough of Mountain Lakes in securing grant funding from the New Jersey Highlands Council to develop a comprehensive Lake and Watershed Management Plan for nine lakes within the Borough. Also noteworthy: of the 17 total 319(h) grants awarded statewide this year, we’re proud to be a partner on five, demonstrating our commitment to advancing watershed restoration and sustainability.
In partnership with Friends of Hopewell Valley Open Space, we kicked off a groundbreaking research project: “Monitoring Harmful Algal Blooms (HABs) in the Delaware River Watershed Using Drones and Spatial Analysis.” Funded by the National Fish and Wildlife Foundation through the Delaware Watershed Conservation Fund, this $1M initiative leverages drone technology, advanced data modeling, and community science to improve forecasting and management of HABs across a 73-mile stretch of the Delaware River and 23 associated waterbodies. We conceptualized and designed the project and are leading technical implementation, including field survey design, drone operations, data analysis, and volunteer training. By integrating drone-based remote sensing, on-the-water sampling, and spatial analysis, we aim to develop predictive tools for early detection and mitigation of HABs, helping protect drinking water supplies, wildlife, and local economies. This collaborative effort includes partners such as NYC College of Technology, Trenton Water Works, Mercer County Park Commission, The College of New Jersey, Aqua-PA, Philadelphia Water Department, Bucks County Conservation District, and Turner Designs. Data collection began in August will resume in Spring/Summer 2026 and culminate in 2027 with a final report.

And, along with Crow Holdings, we were chosen for the United Away "Spirit of Philanthropy” Award.
In New York, we completed the Spring Creek North Ecosystem Restoration Project, revitalizing 43 acres of degraded habitat within the historic Jamaica Bay salt marsh system. The project restored a mosaic of ecosystems, including low marsh, high marsh, scrub-shrub wetland, and maritime upland, through activities like recontouring uplands to intertidal elevations, thin-layer sand placement, invasive species removal, and native plantings. This effort improves water quality, biodiversity, and wildlife habitat, contributing to the long-term health of Jamaica Bay. In the Meadowlands of New Jersey, we helped design and build the Steven R. Rothman Overlook and Preserve, a new five-acre public open space within the 587-acre Richard P. Kane Natural Area. The site offers ADA-accessible trails, sweeping views of the Meadowlands and NYC skyline, and a gateway into one of the state’s most ecologically significant landscapes along the Atlantic Flyway. We provided environmental, civil, and geotechnical engineering, landscape architecture, and construction oversight, ensuring the space honors decades of conservation work while creating opportunities for community connection and nature-based recreation.
Our team continues to shine, reaching new heights in research, professional development, and industry leadership.

Princeton Hydro teamed up with Billion Oyster Project, AKRF, and Monmouth University to explore how restored oyster reefs are revitalizing New York City’s waterways. The project, “Monitoring of Mobile Estuarine Organisms at Restored Oyster Reefs,” combines hands-on species surveys with cutting-edge environmental DNA (eDNA) analysis to capture a complete picture of reef biodiversity. As the field sampling lead, our team conducted monitoring at sites including Brooklyn Bridge Park, Bush Terminal Park, Flushing Bay, and Paedergat Basin. These efforts revealed a diverse array of estuarine life, from schooling fish to a surprise dogfish, and collected eDNA samples for advanced species detection. By integrating traditional sampling with innovative genetic tools, this collaboration is helping refine strategies for scaling up oyster reef restoration and strengthening the ecological resilience of New York Harbor.
This year, Princeton Hydro shared expertise on the global stage and celebrated major milestones in international river restoration. Senior Technical Director of Ecological Services Dr. Fred Lubnow traveled to Lisbon, Portugal, for the 17th International Symposium on Aquatic Plants, where he presented on managing submerged aquatic vegetation to prevent harmful algal blooms. Director of Aquatics Michael Hartshorne spoke at the Southern African Society for Aquatic Scientists Congress in Pietermaritzburg, South Africa, an event that convened researchers, industry professionals, and government leaders to advance aquatic science through collaboration and applied research. President Geoffrey M. Goll, PE, participated in a symposium in Durban, South Africa, focused on Dam Management and Restoration of River Connectivity organized by Dam Removal South Africa and the Institute of Natural Resources. We also celebrated progress in Portugal: Dam Removal Europe published a new case study on the Perofilho Weir removal and stream restoration project in Santarém for which Geoffrey M. Goll contributed to the removal design, helping reconnect 2.5 km of stream habitat and restore fish passage. In February, we published a blog highlighting Geoffrey's ongoing collaboration in Portugal and his October 2024 visit to key restoration sites, showcasing how barrier removal is addressing river fragmentation and creating a blueprint for future efforts.
We collaborated with the Bucks County Conservation District and Bucks County Planning Commission to launch the Lake Luxembourg Restoration StoryMap, an interactive tool that chronicles the decade-long effort to restore Lake Luxembourg’s Conservation Pool. This dynamic resource combines maps, multimedia, and storytelling to make restoration details accessible to the public. Working with Rutgers University’s Climate Change Resource Center and The Nature Conservancy, we contributed technical expertise to the New Jersey Nature-Based Solutions: Planning, Implementation, and Monitoring Reference Guide. This comprehensive guide offers science-based strategies, case studies, and funding resources to help communities implement nature-based solutions statewide. In partnership with the Borough of Harveys Lake, we developed a ArcGIS StoryMap that chronicles the community’s long-standing commitment to water quality, showcases a pilot project aimed at reducing stormwater nutrient pollution, and connects local efforts to broader Chesapeake Bay watershed health. And, for the Lower Makefield Township Environmental Advisory Council, Geoffrey M. Goll, PE, developed a Rain Gardens 101 step-by-step tutorial on designing and building rain gardens.

Here’s to building on this momentum in 2026 and continuing to make a positive impact together!
Across Eswatini’s rural landscape, geography often dictates opportunity. Rivers that swell during rainy seasons can separate families from schools, healthcare, and markets, making daily routines unpredictable and sometimes unsafe. In the three years before the Imphumelelo Footbridge was completed, five people tragically lost their lives and ten were injured attempting to cross during floods. To help address this challenge, volunteers from the Engineers in Action chapter at Rutgers University joined with other students from the University of Iowa, Hofstra University, and Northwestern University, during the summer of 2025, living and working alongside local communities to build the Imphumelelo Footbridge. Each student chapter is responsible for raising the funds needed to purchase construction materials, making the project both a test of resourcefulness and commitment. For Rutgers students, the experience offered not only the chance to apply technical skills in the field, but also invaluable hands-on learning that deepened their understanding of engineering in practice.
At 108 meters long, the Imphumelelo Footbridge is the second longest bridge completed by the Rutgers Chapter in Eswatini, a small, landlocked country in Southern Africa, funded in part by the Microprojects Programme and constructed through the nonprofit Engineers in Action. Now providing safe, year‑round access for more than 1,320 people, the bridge drastically reduces travel distances to healthcare and schools, while standing as a testament to Rutgers students’ commitment to connecting communities and expanding opportunity.
This video offers a glimpse into the construction process itself, showing how the Rutgers Engineers in Action Chapter worked alongside community members in Eswatini to bring the bridge to life. Viewers can see the challenges that arose, the teamwork that solved them, and the collaborative spirit that carried the project from planning to completion:
The Imphumelelo Footbridge was the result of four months of careful preplanning and two months of intensive construction in southern Eswatini. This was the farthest site Engineers in Action has worked on, located nearly three hours by car from the nearest city. The remote setting added complexity to the project, but it also underscored the importance of building a reliable crossing for the communities who would depend on it.
Construction was not without its challenges. When hoisting the suspension cables, the team’s winch broke because it was old and rusted. With the guidance of local masons, students improvised solutions, even resorting to manually knocking the cables to adjust their height. On anchor pouring day, when several batches of concrete were poured to secure the massive blocks through which the cables run, shifting wood supports forced the team to pause, reassess, and slightly reduce the bearing load to ensure stability. Concrete mixing also presented difficulties, since batches sometimes contained too much water.
Rutgers Engineers in Action Co-President, Ula Sokolowski devised a practical solution: mixing gravel, sand, and cement without water, then combining it with the wetter batch to achieve the correct ratio. Reflecting on the experience, Ula noted, "Much of engineering happens behind a desk, but being on site and contributing directly to the build was a completely different experience. Learning how to do every part of the process was not only valuable, but genuinely fun."
Aito Sterle, who served as a Quality Control Manager on Rutgers project in the previous year, the project was equally transformative. Aito explained, “The experience completely changed my engineering mindset. Traveling gave me a new perspective on life and exposed me to a whole variety of problems that required creative solutions. As a quality control manager, I was able to dive into the nitty‑gritty of bridge building and really understand the ins and outs of the process. Even though we weren’t part of the initial design, we felt connected to it on site — documenting each step, taking precise measurements, and ensuring everything was engineered to a T. It opened my eyes to how engineering truly works in the real world.”
The process was a full collaborative effort between students and community members: mixing concrete, sifting sand, moving rocks, and passing buckets of concrete down long human chains. Local masons built walls from stone, while students documented each step and checked measurements to ensure precision. For many community members, the project offered not only a chance to contribute to lasting infrastructure, but also meaningful daily work in a region where jobs are scarce.
The bridge’s completion was celebrated not only by the Rutgers team and local residents, but also by community leaders. At the handover ceremony, MP David Ngcamphalala of Qomintaba emphasized the power of collaboration, stating, “Nothing is impossible when people work together.”
Engineers in Action Program Manager Ana Jovanovic echoed this sentiment, describing the Imphumelelo Footbridge as “a promise of safety, opportunity, and connection. It will save lives, open access to healthcare, and help the next generation reach their classrooms without fear.”
Local leaders also looked ahead to future development. Bucopho of Sigwe expressed gratitude to the Microprojects Programme and appealed for continued support, noting that the dedication of Members of Parliament, Indvuna Yenkhundla, and community leaders gave him confidence that more projects would follow in Qomintaba and Matsanjeni South.
These reflections, reported in the Africa-Press – Eswatini, highlight how the Imphumelelo Footbridge was not only a technical achievement but also a symbol of partnership, resilience, and hope for the communities it serves.
Beyond construction, the Rutgers Engineers in Action team immersed themselves in local life. Prior to travel, students studied language and cultural traditions with the help of a Cultural Relationships Manager, preparing them to build genuine connections. Once in Eswatini, those connections flourished. Community members welcomed the students warmly, eager to share experiences and perspectives.
Every Saturday, soccer matches and games brought students and residents together. Music often filled the downtime at the construction site, with dance becoming a universal language that bridged cultural and linguistic gaps. Families opened their homes to the volunteers, with one household affectionately adopting the students for the duration of their stay.
For Rutgers students, these relationships were as impactful as the bridge itself. The project was not only about engineering a structure, but also about building trust, friendship, and mutual respect across cultures.
Engineers in Action began in 2009 as an international nonprofit dedicated to connecting isolated communities to essential resources through sustainable infrastructure projects. Originally linked with the Bridges to Prosperity program, Engineers in Action has expanded its mission to include not only footbridges, but also water and sanitation systems that empower underserved communities. Student chapters across the United States and Canada have played a vital role in advancing this mission, gaining hands-on engineering experience while helping communities overcome barriers to education, healthcare, and economic opportunity.
To continue building bridges and expanding access to vital resources, Engineers in Action relies on donations. Contributions directly fund materials, logistics, and training that make future projects possible. Supporting Engineers in Action means helping students like those from Rutgers bring their skills to communities in need, while ensuring that families around the world can safely reach schools, hospitals, and markets.

Friends of Hopewell Valley Open Space (FoHVOS), in partnership with Princeton Hydro, has launched a groundbreaking initiative, “Monitoring Harmful Algal Blooms (HABs) in the Delaware River Watershed Using Drones and Spatial Analysis,” to improve understanding and forecasting of HABs throughout the Delaware River Watershed. Funded by the National Fish and Wildlife Foundation (NFWF), in partnership with the U.S. Fish & Wildlife Service, through the Delaware Watershed Conservation Fund (DWCF), the project leverages drone technology and advanced data modeling to identify environmental conditions that contribute to HAB formation and aims to develop tools and methodologies for early detection and management.
For this innovative research project, FoHVOS, a 501(c)3 and accredited Land Trust located in Hopewell Township, NJ, has teamed with Princeton Hydro. Princeton Hydro conceptualized and designed the initiative and is leading the technical implementation, including field survey design, drone operations, data analysis, and volunteer training.
“The Delaware River is central to Hopewell Valley’s identity. It shapes our way of life, supplies drinking water to 14.2 million people, shelters wildlife like the endangered Atlantic sturgeon, and offers abundant outdoor recreation,” said Jennifer Rogers, Executive Director of FoHVOS. “HABs were once confined to ponds and lakes, but since 2018, they’ve appeared in colder months and spread to streams and rivers. Though land trusts traditionally focus on land, HABs show how land use directly affects water. These blooms often stem from excess nitrogen and phosphorus washed into waterways during storms. Protecting water means restoring land. Our partnership with Princeton Hydro aligns perfectly with our mission. Together, we’re working to better understand and safeguard the Delaware River and its tributaries in both NJ and PA.”
HABs, caused by nuisance growth of cyanobacteria, can have detrimental effects on water quality and are a growing environmental concern nationwide. These blooms deplete oxygen levels, release toxins, and disrupt ecosystems, potentially posing serious risks to drinking water supplies and the health of wildlife, pets, humans, and local economies. Despite advances in environmental monitoring, predicting when and where HABs will occur remains a challenge due to the complex interplay of nutrient loading, temperature, and hydrologic conditions that can lead to rapid bloom proliferation.
To address these challenges, this newly launched initiative integrates drone-based remote sensing, field sampling, and spatial data analysis to collect and interpret detailed environmental data over a two-year period. The study spans multiple monitoring sites along a 73-mile stretch of the Delaware River in New Jersey and Pennsylvania, focusing on near-shore sections and 23 associated waterbodies. The first survey event began in August 2025.
Drones equipped with multispectral imaging systems capture high-resolution spatial data that is then integrated with digital platforms to link remote-sensing with the drone data and on-the-water collected data. The field-based water quality measurements are being collected by a team of trained community volunteers who are using phycocyanin fluorometer meters to measure concentrations of the photosynthetic pigment phycocyanin, which is produced primarily by cyanobacteria. Volunteers enter the data into a customized ArcGIS mobile-friendly survey. These combined datasets will be used to develop and validate predictive algorithms for both planktonic and benthic HABs under varying seasonal and hydrologic conditions.
The following photos depict the RGB (Visual) and corresponding Thermal image from the monitoring flights over Spring Lake in New Jersey:
“This research project represents a major step forward in how we study and manage harmful algal blooms at the watershed scale,” said Dr. Fred Lubnow, Project Lead and Senior Technical Director of Ecological Services at Princeton Hydro. “By integrating satellite data, drone imagery, and on-the-water sampling, we’re developing predictive tools that will enable us take a proactive approach to mitigate HABs, improve response time, and better support our ecosystem health.”
Project partners include New York City College of Technology – The City University of New York, which donated the drone and is supporting remote sensing and data integration; Trenton Water Works, Mercer County Park Commission, and The College of New Jersey which are providing monitoring sites and contributing volunteers for water quality data collection in New Jersey; Aqua-PA and the Philadelphia Water Department, which are providing monitoring sites and volunteers to collect watershed data in Pennsylvania; the Bucks County Conservation District, which is coordinating volunteer data collection; and Turner Designs, whose advanced phycocyanin sensors are being used to calibrate and validate drone-based monitoring data.
In the photos below, volunteers are being trained by Princeton Hydro staff on how to use phycocyanin fluorometers and Secchi disks to gather water quality data and log their findings.
This $1M project is funded through a $488,400 NFWF DWCF grant as part of the NFWF’s Research, Monitoring, & Evaluation Grant category and $513,700 in matching funds from project partners. This grant category aims to support high-performing science that is inclusive, adaptive, and innovative, with the potential to transform the Delaware River Watershed’s future through improved conservation, restoration, and public engagement.
Once complete, the project will produce a comprehensive report summarizing methods, analyses, and data-driven recommendations for practical, low-cost HAB monitoring and mitigation strategies that can be replicated across the Delaware River Watershed and beyond. Crucially, the report will identify tributaries and sources contributing to riverine HABs, enabling targeted restoration of the most affected lands and waters. Data collection will continue through Fall 2025, resume in Spring/Summer 2026, and culminate in a final report expected in 2027.

The New Jersey Department of Environmental Protection (NJDEP) recently announced $8 million in Water Quality Restoration Grants to support projects that reduce nonpoint source pollution, mitigate harmful algal blooms, restore riparian areas, and enhance watershed and climate resilience. Funded through Section 319(h) of the federal Clean Water Act and administered by the DEP's Watershed and Land Management Program, these grants were awarded to municipalities, nonprofit organizations, and academic institutions across the state.
Princeton Hydro is proud to be a partner on five of the 17 funded projects. Our contributions vary by project and encompass activities such as engineering design, water quality assessment, watershed-based planning, and technical support for implementing stormwater and habitat restoration measures. Let's take a deeper look at these collaborative efforts:
The Watershed Institute received $205K in 319(h) grant funding to develop a watershed-based plan for the Assunpink Creek watershed, located within the Raritan River Basin. This watershed spans 11 municipalities across two counties, where varied landscapes and demographics share common challenges such as localized flooding, stormwater management, and water quality degradation, highlighting the need for a coordinated, watershed-wide, science-driven approach.
The plan will evaluate pollution sources and identify large-scale restoration opportunities, including green infrastructure and riparian buffer restoration, to improve water quality and reduce flooding. It will also assess the cost, feasibility, and pollutant reduction potential of proposed measures to ensure practical implementation. Princeton Hydro supported the Institute in developing the grant proposal and planning framework, leveraging our expertise in watershed-based planning to prioritize nature-based solutions that address both water quality and climate resilience. This initiative represents a critical step toward regional collaboration, enabling upstream and downstream communities to work together on strategies that strengthen watershed health, protect public safety, and build long-term resilience.
The Lake Hopatcong Commission (LHC) was awarded $366K to retrofit an existing stormwater detention basin between King Road and Mount Arlington Boulevard in Roxbury Township. This retrofit is part of a larger Watershed Implementation Plan that Princeton Hydro developed in collaboration with LHC, which prioritizes nutrient reduction and stormwater management strategies across the Lake Hopatcong watershed. Over the past several years, LHC has actively implemented multiple elements of this plan to address harmful algal blooms (HABs) and improve water quality.
For this project, Princeton Hydro is providing engineering design and technical oversight to transform the existing basin into a green stormwater infrastructure system that slows, captures, and naturally treats runoff before it enters King Cove. The design incorporates native vegetation, invasive species management, and erosion control measures to stabilize soils and filter pollutants, reducing nutrient loading, which is one key driver of HABs. Public outreach and pre- and post-construction water quality monitoring will ensure performance tracking and measurable improvements. This basin retrofit represents a critical step in a coordinated, science-based approach to restoring ecological health and water quality in New Jersey’s largest lake.
Jefferson Township received $350K in grant funding to develop an Emerging Contaminants Management Plan for Cozy Lake, focusing on cyanotoxins and HABs. Cozy Lake is a 28-acre waterbody within a 1,152-acre sub-watershed that includes both forested (60%) and developed (29%) land. The lake is fed by the Rockaway River at its northern end and a smaller southeastern inlet, with outflow through a dam on the western edge.
The shoreline is primarily residential lawn with minimal emergent wetlands, and several inlets and rock-lined drainage ditches exhibit erosion and lack slope protection, contributing to sediment loading. Princeton Hydro provided early technical input to shape this innovative project with the creation of a comprehensive Jefferson Township Lake and Watershed Restoration and Protection Plan. As part of the plan, Princeton Hydro made recommendations for Cozy Lake, which included enhancing shoreline buffers with native vegetation and installing living shorelines at select properties to stabilize soils, filter stormwater and reduce nutrient loading, improve habitat quality, and enhance community access. These measures, combined with in-lake monitoring and proactive management strategies, will help mitigate HABs and protect ecological and public health.
Rockaway Township received $399K in grant funding to implement elements of its Watershed Implementation Plan, focusing on green infrastructure stormwater management and nutrient reduction to improve water quality. The project will retrofit the municipal complex by converting a rock-lined drainage swale into a vegetated swale with a bioretention basin, designed to filter stormwater runoff and reduce nonpoint source pollutants entering Fox’s Pond and Fox Brook.
Princeton Hydro played a key role in developing the Watershed Implementation Plan, which encompasses 11 private lakes within the Rockaway River watershed, prioritizing critical locations for intervention and designing cost-effective green infrastructure BMPs. This regional approach aligns with strategies recommended by NJDEP and the Highlands Council. The plan included a comprehensive watershed-based assessment to identify and quantify factors contributing to eutrophication, evaluate management measures, estimate costs, and establish an implementation schedule. Princeton Hydro authored the final report, which guided the Township in applying for the Section 319(h) grant and now informs the design and construction of green stormwater infrastructure that will deliver measurable water quality improvements while supporting ecological restoration goals.
Green Trust Alliance (GTA), a nationally accredited land trust and public charity dedicated to accelerating large-scale conservation, received $1.39 million in NJDEP funding to implement green infrastructure improvements at Pinelands Regional High School in Tuckerton, New Jersey. This initiative targets the Tuckerton Creek watershed, which drains into Tuckerton Creek and ultimately flows into Barnegat Bay—a critical estuary spanning 33 municipalities in Ocean County and four in Monmouth County. The retrofit will transform the school’s stormwater detention basin into a multi-functional system that mimics natural hydrology, enhances flow control, and improves water quality locally and in the larger Barnegat Bay watershed.
Working with GTA and GreenVest, Princeton Hydro is serving as the design engineer, applying nature-based engineering and ecological restoration techniques to intercept, evapotranspire, and infiltrate stormwater runoff at its source. In addition to its technical objectives, the effort includes a strong community engagement component and an educational platform for students. By bringing green infrastructure into the school environment, the initiative provides hands-on experience with water resources, stormwater management, and ecological engineering, help to build STEM skills while fostering a deeper connection to the surrounding landscape and an understanding of how natural systems work together to support environmental and community health.
Princeton Hydro also assisted several of these partners in developing successful NJDEP Section 319(h) grant applications, providing technical documentation, conceptual designs, and pollutant load reduction estimates to strengthen the proposals.
To date, the Murphy Administration has awarded more than $33M in Water Quality Restoration grants to improve the health of waterways in all corners of the state. Click here to read about all the 2025 grant funding recipients and their innovative projects.
As NJDEP Environmental Protection Commissioner Shawn M. LaTourette noted in the department's press release, “Enhancing the ecological health of our lakes, rivers, streams and coastal waters has long been a priority of the Murphy Administration. The Department of Environmental Protection is pleased to award these grants that will help our partners advance a variety of strategies to improve the health of these waterways and enhance the quality of life in our communities.”

Welcome to our Partner Spotlight blog series, where we highlight the meaningful collaborations and shared successes Princeton Hydro enjoys with our valued partners. Today, we’re shining the spotlight on Save Barnegat Bay, a nonprofit rooted deeply in environmental advocacy and stewardship, dedicated to safeguarding Barnegat Bay.
Fed by freshwater inputs from rivers, creeks, and streams, and saltwater from the Atlantic Ocean, Barnegat Bay is a unique estuary stretching approximately 42 miles from Bay Head to Long Beach Island and the Little Egg Harbor inlet. Barnegat Bay is the largest body of water in New Jersey and one of the region’s most valuable natural resources.
Save Barnegat Bay, founded in 1971 by neighbors concerned about the future of their local waterways, has grown into a highly respected, effective, and influential voice for environmental protection throughout the state. Through advocacy, education, restoration, and community engagement, the organization is leading the charge to preserve the Barnegat Bay ecosystem and the wildlife and communities that call it home.
For this Partner Spotlight, we spoke with Britta Forsberg, Executive Director of Save Barnegat Bay, who brings decades of personal and professional commitment to protecting this vital resource.
Let’s jump in!
“What truly sets Save Barnegat Bay apart is our hyper-local approach. We’re not a Washington, D.C.-based environmental group, we’re right here in the Barnegat Bay Watershed, working directly with the communities we serve. For 54 years, we’ve remained a steady and effective environmental voice, and we’ve achieved meaningful, lasting impacts through persistence, collaboration, and grassroots engagement.”
In the video below, Britta shares more about the guiding vision behind Save Barnegat Bay’s work and what continues to fuel the organization’s success:
“Save Barnegat Bay’s work spans decades and addresses a wide range of threats to the watershed, from nutrient pollution to legacy contamination. One of our most impactful successes is the passage of the New Jersey Fertilizer Law, which we wrote and lobbied for. It remains the strictest fertilizer content law in the country. This effort began with local ordinances, but we quickly realized a patchwork of municipal laws wasn’t effective. So, we pursued statewide legislation to reduce nitrogen pollution, a major stressor for Barnegat Bay’s ecological health. This law has helped prevent millions of tons of nitrogen from entering New Jersey’s waterways.
Another critical focus for us is environmental justice and accountability. We’re currently challenging a controversial settlement related to the Ciba-Geigy Superfund Site in Toms River. This site has a painful history: decades ago, a chemical plant discharged toxic waste into rivers, groundwater, and even the Atlantic Ocean, resulting in significant health impacts, including a well-documented childhood cancer cluster. While criminal charges and civil suits were eventually brought, we’re now fighting for appropriate restitution. We believe the NJDEP’s current settlement with the site’s owner, BASF, the world’s largest chemical company, lacks transparency and fails to account for the full environmental damage. We’ve filed an appeal and are advocating for a more just and science-based resolution that considers the lasting damage to 1,200 acres of land, the groundwater, wetlands, river, bay, and ocean.
We’re also proud to have played a leading role in the closure of the Oyster Creek Nuclear Generating Station, once the oldest operating nuclear plant in the country. The plant’s design used Barnegat Bay water to cool its reactors, then discharged superheated water back into the estuary, devastating marine life daily. We believe Save Barnegat Bay is the only grassroots environmental organization in the U.S. to successfully close a nuclear plant not on the basis of nuclear energy itself, but on its local ecological impacts.
These are just a few examples of the many efforts Save Barnegat Bay has led or supported over the years. From legislative advocacy to grassroots mobilization, our work is broad and ongoing. What unites it all is our deep commitment to protecting the Bay and ensuring its health for generations to come.”
“Barnegat Bay relies on a delicate and often overlooked network of 58 named rivers, creeks, and streams. Many of these freshwater sources originate in the Pine Barrens, winding through Ocean County and parts of Monmouth County before reaching the Bay. They are the lifeblood of the estuary, delivering freshwater that supports the Bay’s health, biodiversity, and overall ecological function.
Our “Rivers, Creeks, and Streams” campaign was created to inspire and connect people with their local waterways and take part in their protection. Whether it's through cleanup activities, water sampling, or making simple, eco-friendly changes at home, we believe small actions can collectively have a big impact.
Thanks to the generosity of local businesses, we've been able to acquire a fleet of canoes and kayaks to get people, including elected officials and community leaders, directly out on the water. This hands-on approach helps participants build a personal relationship with their local water resources, see firsthand the challenges and opportunities for improvement, and feel empowered to help. It’s one thing to talk about water quality in a meeting room, it’s another to experience it on the water, paddle in hand.”
In the video clip below, Britta shares more about this unique initiative:
“Over the years, we’ve collaborated with Princeton Hydro on a wide range of impactful projects. We've worked with many members of their team, including Dr. Steve Souza; Dr. Fred Lubnow; Geoffrey Goll, P.E.; and Mark Gallagher, just to name a few. Our work together has spanned everything from technical restoration projects to public education initiatives. In fact, we’ve probably partnered with a good portion of their staff at some point on various critical initiatives across the watershed.”
In the video clip below, Britta highlights two collaborative projects that stand out as major wins, successfully protecting sensitive habitats while navigating the priorities of various stakeholders:
Britta continues: “We’re also partnering with Princeton Hydro to take a proactive approach to water quality management in coastal towns throughout the Barnegat Bay Watershed. Specifically, we’ve been supporting Point Pleasant Beach and Bay Head in developing comprehensive lake and watershed management plans. There are three coastal lakes in Point Pleasant and one in Bay Head, and these proactive planning efforts have been incredibly valuable for those communities.
Honestly, I could go on and on. We’ve worked with Princeton Hydro on so many important projects together; it’s a true partnership.”
“There are so many ways to get involved. At Save Barnegat Bay, we encourage people to contribute and participate in whatever way works best for them—time, treasure, or talent. Nearly everything we offer is free and open to the public, from hands-on workshops like rain barrel construction to science-based programs like eelgrass planting and clinging jellyfish monitoring to volunteer initiatives like shoreline clean-ups. We’re not a membership-based organization, which means there’s no barrier to participation. You can simply show up and engage in whatever way feels right to you.
Britta leaves us with a few inspiring words about the power of big ideas, and a reminder to look beyond the everyday and believe in what’s possible:
