As part of the study, Princeton Hydro is reassessing previously identified drainage features and conducting a comprehensive site evaluation to better understand how conditions have changed over time and where new problem areas have emerged.
At the first public meeting earlier this month, community members played an active role in shaping the direction of the study. The session began with an overview of the project’s purpose, scope, and methodology, including preliminary findings on areas most vulnerable to flooding, sediment discharge, and streambank instability. Attendees also had the opportunity to ask questions and engage directly with the project team, helping to build a shared understanding of the challenges facing the park.
Following the presentation, participants took part in an interactive mapping exercise designed to gather site-specific knowledge from those who know the park best. Working in small groups around large, printed maps of the study area, attendees identified flood-prone zones, areas of active erosion, and locations where trail conditions have declined over time along Forbidden Drive and its access points. Participants marked up the maps and shared observations, stories, and ideas for potential restoration opportunities, creating a collaborative and hands-on dialogue about the park’s needs.
This exercise generated valuable, location-specific insight that is already informing the study. Participants highlighted:
In addition to identifying problem areas, attendees also shared perspectives on what makes the park special and where restoration efforts could have the greatest impact. This type of feedback is critical to ensuring the study reflects real-world conditions and community priorities. To ensure the most comprehensive understanding of conditions in the targeted areas, the project team is looking to hear from an even broader range of park users.
While engineers and scientists are conducting in-depth field investigations and comprehensive technical analyses, they do not experience the park in the same way as those who use it regularly. The firsthand perspective of park visitors is invaluable for identifying problem areas and guiding solutions and priorities that truly reflect how the park is used and experienced.
Gloucester County’s Scotland Run Nature Preserve is a place where education, recreation, and ecological diversity come together. As the largest park in the county system, spanning more than 1,300 acres, Scotland Run offers visitors a chance to explore a wide range of habitats including woodlands, open fields, streams, and lakeside environments. Situated along the boundary of New Jersey’s Inner and Outer Coastal Plains, the park reflects features of both Piedmont and Pine Barrens landscapes, supporting a remarkable variety of wildlife.
At the center of the park is Wilson Lake, an 80-acre man-made lake created by a historic dam built for Fries Mill on Scotland Run. Today, the lake provides passive recreation opportunities such as fishing, canoeing, and nature observation. An ADA-accessible fishing pier near the boat launch ensures that these experiences are available to everyone. The park is also highly family friendly, with maintained walking trails, picnic areas, a playground, restrooms, and a Nature Center that serves as a hub for learning and discovery.
This winter, the Nature Center hosted Nature at Night, a popular exploration series that invites community members to engage with the natural world through hands-on presentations led by environmental professionals. Held on the 3rd Thursday of the month from January to April, topics throughout the series included mammals, fossils, insects, birds, reptiles, and amphibians, offering something for nature lovers of all interests.
Princeton Hydro Senior Wildlife Biologist Mike McGraw, CSE, QAWB, ACE led an engaging and energetic program focused on reptile and amphibian evolution, morphological adaptations, and the incredible diversity found right here in New Jersey.

Conservation professionals, land stewards, and researchers from across New Jersey gathered for the New Jersey Invasive Species Strike Team Conference, the most comprehensive statewide forum dedicated to invasive species management. The conference was presented by Friends of Hopewell Valley Open Space (FoHVOS), an accredited nonprofit land trust committed to land protection, resource conservation, and community engagement.
The conference was held at the Boathouse at Mercer Lake, which provided an ideal backdrop for a day focused on protecting New Jersey’s natural landscapes. The conference, which Princeton Hydro was proud to sponsor, included exhibitor tables, networking opportunities, and a variety of presentations. The day kicked off with welcome remarks from Jenn Rogers, Executive Director of FoHVOS, and representatives from Mercer County Parks. Educational sessions throughout the day explored the dynamic and evolving challenges facing New Jersey’s ecosystems, cutting-edge academic research, and practical, field-based solutions for mitigating invasive species:
Native to the Yangtze and Amur River basins in China, the silty pond mussel (Sinanodonta woodiana) is a highly invasive freshwater species that has spread worldwide, often without detection. Its life cycle makes early identification especially difficult: microscopic larvae, known as glochidia, attach to the gills of host fish, allowing the mussel to move unnoticed through connected waterways and establish new populations far from their point of origin.
This stealthy mode of transport is believed to be how the silty pond mussel arrived in the United States. The species was first documented in 2010, when it was discovered in New Jersey Conservation Foundation’s Wickecheoke Creek Preserve, which previously operated as a fish farm and is now protected land. Although the mussel had likely been present for several years, its absence from North American records meant it went undetected until genetic confirmation was completed. Investigations identified invasive bighead carp imported for aquaculture as the most likely pathway of introduction.
The discovery raised immediate concern because of the preserve’s ecological significance. Located in Hunterdon County, the Preserve supports nearly 400 native plant species and 14 miles of high‑quality streams. It sits at the headwaters of Wickecheoke Creek, a tributary of the Delaware River that connects to the Delaware and Raritan Canal, part of a drinking water system serving approximately one million New Jersey residents.
Once established, silty pond mussels can overwhelm aquatic ecosystems. During the presentation, Scott Churm and Dr. Emile DeVito explained that invasive mussels may account for over 75% of total benthic biomass in affected waterbodies. Such dominance can disrupt food webs by outcompeting native mussels; harm fish when larvae attach to their gills, sometimes triggering fatal biological responses; reduce biodiversity; and alter water chemistry, ultimately degrading habitat quality for both plants and animals.
Following the initial discovery of the silty pond mussel, testing conducted by the New Jersey Invasive Species Strike Team, the New Jersey Endangered and Nongame Species Program, and the North Carolina State Museum of Natural Sciences confirmed the presence of this invasive species. With confirmation in hand, early eradication efforts began, centered on careful detection and sustained monitoring to better understand the scope of the infestation.
To assess the extent of the mussel’s presence, response teams combined traditional field surveys with advanced scientific techniques. This integrated approach included SCUBA and snorkel surveys, physical sampling of mussels and stream substrates, and environmental DNA (eDNA) testing, which detects trace genetic material released by organisms into the water and allows scientists to identify species that may not yet be visible during field inspections.
Together, these methods made it possible to find both established populations and early-stage infestations. In 2021, researchers applied highly sensitive genetic markers developed by Rutgers University to determine whether the silty pond mussel had escaped the former aquaculture ponds and spread into surrounding waterways. Initial eDNA sampling focused on Wickecheoke Creek Preserve, where testing provided a clearer picture of the species’ distribution and helped validate findings from visual surveys.
Monitoring efforts later expanded beyond the preserve. In 2021 and 2022, water samples collected from the Raritan River at the confluence of the Millstone and Raritan Rivers produced positive eDNA detections for silty pond mussel. These results pointed to the potential presence of a population within the Raritan River Watershed and highlighted the need for a rapid, coordinated response to prevent further spread.
Together, these methods made it possible to identify both established populations and early-stage infestations. Initial eDNA sampling focused on the preserve, where testing provided a clearer picture of the species’ distribution and helped confirm results from visual surveys. Based on those findings, monitoring efforts expanded to connected waterways where the researchers applied highly sensitive genetic markers developed by Rutgers University to determine whether the silty pond mussel had escaped the former aquaculture ponds and spread beyond Wickecheoke Creek Preserve. In 2021 and 2022, water samples collected from the Raritan River at the confluence of the Millstone and Raritan Rivers yielded positive eDNA detections for silty pond mussel. These results indicated the possible presence of a population within the Raritan River watershed and reinforced the need for a rapid, coordinated response to limit further spread.
Eradication efforts at Wickecheoke Creek Preserve began with extensive planning and regulatory review to ensure treatments would be both effective and protective of surrounding ecosystems. Before field work could proceed, the project team secured all required state permits, verified pond depth and water volume to calculate precise treatment dosages, posted public notices and signage throughout the site, and established protocols for daily safety briefings and site inspections. This preparation ensured the project was conducted safely, transparently, and in full compliance with permit requirements.
Following this approval phase, Princeton Hydro’s licensed applicators, working closely with SePRO and project partners, implemented a targeted treatment using Natrix®, an EPA-registered chelated copper pesticide formulated specifically for invasive mollusk control. Treatments were designed to maintain copper concentrations at 1 part per million for a minimum of 96 hours. To ensure consistent and accurate dosing, water samples were collected and analyzed twice daily at an onsite laboratory throughout the treatment period.
This work is part of an adaptive, science-driven eradication strategy that depends on clear roles and close collaboration among partners. The approach is both preventative and responsive, allowing the team to adjust tactics based on monitoring results and site conditions. The project is supported by funding from the U.S. Fish and Wildlife Service and the Delaware River Greenway Partnership through the Lower Delaware Wild and Scenic Program.
Looking ahead, the work at Wickecheoke Creek Preserve reflects the themes emphasized by Scott and Emile during their presentation: the importance of early detection, scientific innovation, and coordinated response in addressing invasive species. Continued collaboration among scientists, agencies, conservation organizations, and local communities strengthens the ability to respond quickly and adaptively, while education and public awareness support long-term prevention. Together, these efforts contribute to the protection of native species and freshwater systems and support the ongoing stewardship of our natural spaces.
From tidal estuaries and back bays to nearshore marine waters, New Jersey’s coastal environments support fisheries, recreation, wildlife, and local economies. Increasingly, however, these valuable ecosystems are vulnerable to a wide range of harmful algal blooms (HABs). While algae are a natural and essential part of aquatic ecosystems, certain environmental conditions can cause some species to grow excessively, leading to ecological damage, public health risks, and economic losses.
Understanding what HABs are, what drives them, and how nature‑based restoration strategies can prevent or mitigate blooms is essential to supporting the long‑term resilience of New Jersey’s coastal environments.
The term "algae" is ecological rather than taxonomic and encompasses a diverse group of organisms, including eukaryotic algae, such as diatoms and dinoflagellates, and prokaryotic cyanobacteria, commonly referred to as blue‑green algae. Algae are not inherently harmful. In fact, they provide critical ecosystem services, including:
Phytoplankton are microscopic, free‑floating algae found in freshwater, estuarine, and marine environments. Scientists estimate there are 20,000 to more than 100,000 phytoplankton species, but only a small fraction—roughly 100 to 300 species—are capable of forming toxin‑producing harmful algal blooms. Problems arise when these species proliferate rapidly under favorable conditions. These blooms can become harmful when they produce toxins, deplete oxygen, shade submerged vegetation, or otherwise disrupt ecosystem function.
While most harmful algal blooms are caused by phytoplankton, large, fast‑growing macroalgae can also create serious environmental and economic challenges when conditions allow them to proliferate. A well‑known example is Sargassum, a floating seaweed that can form extensive mats across the ocean surface. During periods of rapid growth, these mats can block sunlight from reaching coral reefs and other sensitive habitats. When Sargassum washes ashore in large quantities, it can deter tourism and recreation. As the algae decomposes, it releases hydrogen sulfide gas, producing strong odors that make nearby coastal areas unpleasant to visit. While Sargassum blooms occur most summers along the coast of south Florida, the severity and extent of these events vary considerably from year to year.
HABs can form in freshwater systems, brackish estuaries, and coastal marine waters, and they are particularly dangerous with myriad when they produce toxins that affect humans, pets, livestock, fish, shellfish, and wildlife.
Below is a closer look at the dominant types of marine HABs in the region, the organisms responsible, and the environmental conditions that influence their development.
Brown tides are associated with several diatom genera, such as:
These blooms are influenced by a combination of physical, chemical, and climatic factors, including:
Ulva, commonly known as sea lettuce, is a green macroalga that can form extensive blooms in shallow, nutrient‑rich estuaries. Another common bloomer, Enteromorpha, is now considered genetically equivalent to Ulva. Although Ulva blooms are non‑toxic, they can still cause serious ecological and social impacts:
Cyanotoxins should not be confused with taste‑and‑odor (T&O) compounds. Cyanotoxins are colorless, tasteless, and odorless whereas T&O compounds, such as geosmin and MIB, cause earthy or musty smells. Cyanobacteria can produce T&O compounds without toxins as well as toxins without noticeable odors.
This distinction can complicate detection and public perception of risk.
These HABs, the region's most common, illustrate the wide range of organisms, toxins, and ecological pathways through which algal blooms can affect coastal systems. Although they differ in form, from microscopic phytoplankton to expansive mats of macroalgae, they are often driven by a common set of environmental conditions that favor rapid growth and persistence. Climate change is intensifying many of these drivers. Rising water temperatures, altered precipitation patterns, and longer periods of stratification increasingly create conditions that favor bloom formation. At the same time, human activities continue to increase excess nutrients to coastal waters. Runoff from agricultural lands, chemicals transported by rainfall and irrigation, and discharges from wastewater treatment facilities all introduce nitrogen and phosphorus into rivers, lakes, and estuaries. These nutrients act as fertilizer for algae, accelerating bloom development.
Nutrient‑laden stormwater runoff does not remain localized, rather, it moves downstream through interconnected watersheds, ultimately reaching estuaries and coastal waters where it can contribute to marine blooms. Understanding these linkages between land use, climate, and algae growth is critical to identifying effective strategies for preventing and managing HABs in coastal environments.
This Earth Day, students from Foundation Academy Collegiate in Trenton, NJ took their learning beyond the classroom through an immersive placemaking workshop hosted by Princeton Hydro. Designed as a real‑world, community‑based challenge, the experience invited students to reimagine a section of Trenton currently under study as part of the proposed Route 29 relocation project, which aims to reconnect the community to the Delaware River.
The goal was simple but powerful: give students a firsthand look at how planning, engineering, and community engagement shape the places they live, and let them experience those processes in action.
To start the workshop, students explored the basics of land use, Trenton’s development history, and the many steps that go into shaping an engineering project. They learned how planning, engineering design, permitting, construction, funding, and community engagement all work together to influence what gets built and why. With support from the "experts," they analyzed printed maps and photos of the selected site, identifying existing conditions and imagining what could be improved.
Once the activity began, the room quickly transformed into a bustling design studio. Each group received a large map of the site and a spread of crafting materials like blocks, clay, paper, and markers. From there, they built their vision for a future Trenton.
Some groups focused on green space and walkability. Others imagined mixed‑use corridors, safer crossings, or new community gathering areas. A few even experimented with stormwater‑friendly designs, weaving in concepts they had learned earlier in the session.
Throughout the activity, the "experts" from Princeton Hydro including an Engineer, Environmental Scientist, Grant Writer, Communications Specialist, Landscape Architect, and Wildlife Biologist, moved between tables, answering questions, offering technical insight, and encouraging students to think about how different stakeholders might view the same space. Residents, businesses, commuters, environmental groups, and city officials all bring different priorities to the table, and the students quickly discovered how complex those perspectives can be. The students were challenged with questions like "How are you going to fund this project?" "What's your engagement strategy to sell this to your peers?" and "How are you going to manage potential flooding from the river or stormwater in the park?"
Becky Taylor, a longtime Trenton advocate, co‑chair of the Cadwalader Park Alliance, and leader of Trenton Walks! also joined the teaching team for the day. Her work supporting Cadwalader Park’s restoration and experience leading dozens of walks throughout the City has connected her deeply with residents across the city. She is a strategic public affairs executive and small business owner, so as she engaged with students, she encouraged them to think about how public spaces carry history, identity, and community memory, and how thoughtful design can help strengthen those connections.
The students also learned something planners and engineers know well: There is rarely a single right answer. Every design choice involves tradeoffs, and every community space should reflect the values of the people who help shape it.
After building their models, each group presented their development plan to the room as if they were selling their vision to their local community in a public meeting. They explained their design choices, highlighted community needs, and described how their ideas could improve quality of life for residents.
The presentations were thoughtful, creative, and deeply rooted in the students’ lived experience. Many spoke about wanting safer streets, more places to gather, and greener, more welcoming public spaces. Others emphasized the importance of honoring Trenton’s history while planning for its future. They designed features such as a flower garden, a pier for fishing, a stormwater park, wildlife habitat, sports fields, and a kid's playground. One group proposed to elevate the new Route 29 so that the community could walk directly from downtown to their new riverfront park without safety issues of crossing a road. Another group deemed the waterfront development "Trenton 2.0" with trees lining the riverfront, renewable wind energy, and raised housing.
For our team, this workshop reinforced what we already know to be true: youth engagement in STEAM education matters. Young people notice how a place feels to move through, where it feels safe or unsafe, and what kinds of spaces are missing in their daily lives. When given the tools, they articulate those needs with confidence. They also tend to think collaboratively, naturally considering community needs alongside their own.
By learning how land use works and seeing the steps behind planning and development, students begin to understand how decisions are made and how those decisions affect the character of their neighborhoods. Most importantly, they start to see themselves as active participants in shaping their city rather than passive observers. Their insights help ground planning conversations in lived experience, and their voices strengthen the long‑term vision for any community project.
We are grateful to Foundation Academies for spending Earth Day with us and for bringing their energy and insight to this design challenge. As the Route 29 relocation/waterfront study continues, we remain committed to creating opportunities for meaningful participation, especially from young people who will inherit the outcomes of today’s planning decisions.
Princeton Hydro recently joined coastal and climate resilience practitioners from across the region at the 2026 New Jersey Coastal & Climate Resilience Conference, hosted by the New Jersey Coastal Resilience Collaborative (NJCRC) and the New Jersey Department of Environment Projection (NJDEP). With this year’s theme, “Navigating Changing Tides,” the three-day conference brought together hundreds of professionals to share ideas, explore solutions, and strengthen the partnerships essential to advancing coastal resilience.
As part of the conference program, Princeton Hydro's Director of Marketing & Communications Dana Patterson Grear organized a Sunrise Bird Walk at Edwin B. Forsythe National Wildlife Refuge, led by Mike McGraw, CSE, QAWB, ACE, Senior Wildlife Biologist at Princeton Hydro, alongside Drew McQuade and Aleshanee Mooney of the New Jersey Sports and Exposition Authority (NJSEA).
A group of 25+ participants traveled the eight‑mile loop along Wildlife Drive, collectively observing 62 bird species along the way. Highlights included two White Ibis, an Osprey perched on a nesting platform, and hundreds of Snow Geese. As the group approached the end of the loop, a Peregrine Falcon provided the perfect send-off, holding its perch on a refuge sign while the caravan rolled by.
Dr. Clay Emerson, PE, CFM, Senior Technical Director of Engineering Services, shared his perspective on New Jersey’s changing coastal environment and the role bay island restoration can play in protecting vulnerable shorelines.
Clay’s presentation explored how coastal dynamics, restoration design, and resilience planning intersect, offering practical insight into nature‑based strategies that support shoreline stability and long‑term adaptability. His ability to translate complex processes into clear, engaging concepts resonated strongly with the conference audience. Moderated by Tom Herrington of the Monmouth University Urban Coast Institute, Clay participated in a Q&A panel discussion with NOAA Coastal Resilience Fellow Heather Korzun and Research Scientist Dr. John Swartz of The Water Institute to conclude the "Building Community Resilience" breakout session.
Dr. Fred Lubnow, Senior Technical Director of Ecological Services, gave a poster presentation focused on Harmful Algal Blooms (HABs) in coastal environments.
Fred’s work examined how HABs behave in dynamic coastal systems, how to identify HABs, and restoration strategies. In the context of the conference theme, his presentation reinforced that HABs are not just seasonal nuisances, but long‑term resilience challenges that require integrated science, monitoring, and restoration approaches.
As part of the conference's Tools Café, Dana Patterson Grear, Director of Marketing & Communications, led a digital storytelling demonstration, titled “Launching an Interactive ArcGIS StoryMap for Public Outreach.” The session demonstrated how digital tools like StoryMaps can be used to translate complex data into accessible narratives that support community engagement, education, and informed decision‑making. Dana guided participants through several ArcGIS StoryMaps created by Princeton Hydro for clients and project partners, showcasing applications ranging from restoration projects and environmental resource inventories to water quality assessments and community science initiatives.
Princeton Hydro was proud to host a conference networking event alongside co‑sponsors Stantec, Baird, and Barnegat Oyster Collective. The gathering created space for conversation, collaboration, and relationship‑building, an essential part of advancing coastal resiliency initiatives and cross‑disciplinary problem‑solving. Attendees enjoyed brief remarks from each of the event sponsors, along with happy‑hour refreshments, and a complimentary oyster bar provided by the Barnegat Oyster Collective. Our team had a great time connecting with colleagues and celebrating the collaborative energy that defined the conference.
Another highlight of the conference for our team was a field trip to The Nature Conservancy in New Jersey’s South Cape May Meadows, where participants explored the newly completed boardwalk, a Princeton Hydro-designed project that creates a half‑mile, universally accessible route through one of the region’s most ecologically significant landscapes. Commissioned by The Nature Conservancy in New Jersey and installed by Renova Environmental Company, the project was designed to provide inclusive public access and opportunities for environmental education while carefully protecting a fragile ecosystem that serves as a vital stopover along the Atlantic Flyway.
Designing a public trail within such a dynamic wetland system required a careful balance between human experience and habitat preservation, with the goal of creating an inviting, educational, and fully accessible route without disturbing critical hydrology, soils, or wildlife. Walking the boardwalk alongside fellow NJCRC Conference participants was a meaningful, full-circle moment for our team, bringing the project’s vision to life.
Huge thanks to New Jersey Coastal Resilience Collaborative and New Jersey Department of Environmental Protection for pulling together another incredible conference. We headed home with new connections, new ideas, and a renewed sense of pride in the work we all do!
Dr. Fred Lubnow, Princeton Hydro's Senior Technical Director of Ecological Services, and Jenn Rogers, Executive Director of Friends of Hopewell Valley Open Space (FoHVOS), were recently featured on the Native Plants, Healthy Planet podcast to discuss the collaborative, first‑of‑its‑kind initiative to monitor Harmful Algal Blooms (HABs) in the Delaware River Watershed using drones, spatial analysis, and community science.
The Delaware River is a lifeline for more than 14 million people, a refuge for wildlife, and a defining natural feature of the region. In recent years, HABs, once confined mostly to lakes and ponds, have expanded into streams and rivers and appearing in colder months. Understanding why this shift is happening, and how to predict it, is essential for protecting water quality, public health, and ecological resilience within the Delaware River watershed and watersheds nationwide.
The podcast, hosted by Fran Chismar and Tom Knezick of Pinelands Nursey, highlights the urgency of addressing HABs and the innovative, cross‑sector partnership driving this work forward. Listen now: Harmful Algal Blooms with Dr. Fred Lubnow and Jenn Rogers.
Jenn Rogers, Executive Director of FoHVOS, brings two decades of conservation leadership to the partnership. Her background spans naturalist education, ecological stewardship, and the development of large-scale restoration and public engagement programs. During her fourteen years with the Mercer County Park Commission, she helped establish both the Environmental Education and Stewardship Departments and oversaw the care of more than ten thousand acres of parkland.
Jenn has spent her career building programs that connect people to the landscapes around them. Her commitment to community-driven conservation make her a key partner in a project that relies on both scientific rigor and public participation. Her perspective highlights how land use, watershed health, and community stewardship are deeply interconnected.
Dr. Fred Lubnow serves as Princeton Hydro’s Senior Technical Director of Ecological Services and brings more than 30 years of experience in limnology, watershed restoration, and community and ecosystem ecology. His career has focused on understanding how freshwater systems respond to nutrient loading, hydrologic change, and long-term environmental pressures. He has designed and led numerous lake and watershed restoration projects, developed USEPA Nine-Element and TMDL-driven watershed plans, and created field-based cyanobacteria and cyanotoxin monitoring programs that are now used across the region.
Fred’s expertise in the taxonomy, ecology, and management of algae, particularly cyanobacteria, has made him a leading voice in the study of HABs. He currently serves on New Jersey’s HABs Advisory Team, where he helps interpret water quality data and advises on mitigation strategies. His scientific leadership guides the technical design and implementation of the Delaware River HAB monitoring initiative.
Now entering its second year, the Delaware River HAB monitoring initiative is expanding both its scientific scope and its community engagement efforts. Building on the foundation established in 2025, the project team is conducting multi‑season drone flights, enhanced satellite‑based surveys, and targeted on‑the‑water sampling along 73 miles of the Delaware River and 24 connected waterbodies. These efforts are designed to strengthen the project’s ability to detect and forecast HABs under a wide range of seasonal and environmental conditions.
Year two also introduces several tools and activities intended to support broader participation and more efficient data collection. This includes the launch of a new ArcSurvey123 mobile data platform to support real‑time volunteer water quality submissions, as well as expanded training opportunities for community members interested in assisting with field sampling. Data collected through these efforts will contribute to the development of advanced algorithms capable of forecasting HAB occurrence at multiple spatial scales.
Funded by the National Fish and Wildlife Foundation's (NFWF) Delaware Watershed Conservation Fund (DWCF), in partnership with U.S. Fish & Wildlife Service, the project continues to be supported by a diverse network of partners across New Jersey and Pennsylvania, including The City University of New York's (CUNY) New York City College of Technology (City Tech), Trenton Water Works, Mercer County Park Commission, The College of New Jersey, Aqua-PA, Philadelphia Water Department, Bucks County Conservation District, Turner Designs, and US Army Corps of Engineers - Philadelphia District's Blue Marsh Lake. Together, these organizations contribute technical expertise, watershed knowledge, and crucial on‑the‑ground support. This collaborative approach remains central to the initiative’s success and long‑term objective: establishing a scalable HAB‑forecasting framework that can ultimately be applied to additional watersheds across the United States.

Municipal ordinances, when thoughtfully drafted and effectively implemented, are among the most powerful tools for protecting watersheds, managing stormwater, preserving forests and wetlands, and reducing flood risk. 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:
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.
Mike McGraw is a Certified Senior Ecologist and Wildlife Biologist with more than 20 years of experience conducting ecological assessments, wildlife surveys, and conservation-focused research across the United States and Canada. His work spans ecological restoration, regenerative agriculture research, and master planning for large landscapes. He teaches Avifaunal Ecology at the University of Pennsylvania and serves on several municipal and land trust committees. Some of Mike’s research on regenerative agriculture has been documented in film.
The webinar was hosted by the Bird Town PA Education Committee of Bird Town Pennsylvania, LLC.
