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.


Protecting Natural Green Infrastructure

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.

[gallery link="none" columns="2" size="full" ids="19253,19254"]

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.


Modernizing Zoning to Reflect Environmental Realities

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.


Legal Foundations and Enforcement

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.

By Mikhail Velez, Communications Coordinator

The New Jersey Department of Environmental Protection (NJDEP) launched its fourth annual Youth Inclusion Initiative. The program hopes to enrich young participants, who may not have the opportunity to explore open spaces in their community, with hands-on environmental field experience under the tutelage of NJDEP professionals and mentors.

This year’s participants consisted of youths from several different community-based organizations. These partners include Neighborhood Improvement Association (Trenton), Rutgers-Camden, The Work Group (Camden), Ranch Hope (Salem), Boys and Girls Club of Garfield, Groundwork Elizabeth, Ironbound Community Corporation (Newark), and United Community Corporation (Newark).

Over six weeks, eight community organizations guided participants as they engaged with professionals to explore careers in water and air monitoring, natural resource management, wildlife conservation, and other related fields. Additionally, a new component of the program introduces "community project days," where participants actively contribute to environmental projects within their neighborhoods. These projects enable participants to make a positive impact on their communities, fostering a sense of civic pride and environmental stewardship. Activities may include park cleanups, installing educational exhibits, and establishing community gardens.

The program has been expanded to include a full day of rehearsal, with a focus on public speaking abilities and mock interviews, regarded as integral components of professional development. Throughout the summer, participants will engage in resume and cover letter writing sessions and attend presentations led by guest speakers.

In addition to fostering personal and professional growth, participants devoted a substantial amount of their time to honing technical skills through hands-on activities. These activities included simulating environmental impact investigations, collecting macroinvertebrates from a stream to gauge water quality, interacting with fish at a state trout hatchery, and designing a park in collaboration with Green Acres staff. To further enrich their understanding, the program also incorporates a visit to the regional headquarters of the U.S. Environmental Protection Agency.

As part of this initiative for the third year in a row, the NJDEP's Division of Land Resource Protection Mitigation Unit invited Princeton Hydro and Mercer County Park Commission to host three sessions at John A. Roebling Park. Under the guidance of Princeton Hydro mentors Mark Gallagher, Dana Patterson Grear, and Mike McGraw,  the team educated young participants about invasive species and the importance of restoring native landscapes. The initiative exposed attendees to the varied roles of environmental scientists, water resource engineers, geologists, restoration ecologists, wildlife biologist, pesticide applicators, regulatory compliance specialists, and communications professionals, thereby enhancing their understanding of these professions and sparking a fascination for the natural world.


The Abbott Marshlands in Trenton, New Jersey

The program began at Tulpehaking Nature Center like in previous years. After representatives from Mercer County Park Commission and Friends of the Abbott Marshlands introduced the site's history, Princeton Hydro discussed career opportunities in conservation and gave a brief overview of ongoing restoration efforts in the park to eliminate the invasive Common Reed (Phragmites australis), and NJDEP representative, Jessica Klein, gave a presentation about her work in wetland mitigation.

Before venturing into the Abbott Marshlands, the northernmost freshwater tidal wetlands along the Delaware River, the Princeton Hydro team conducted a health and safety briefing. They highlighted potential risks and exposures to ensure everyone's awareness. This briefing is a crucial part of prioritizing the safety of all participants in our work.

Shortly after setting out on the road to the site, the students received  an additional lesson. Mark directed their attention to a nearby tree where poison ivy - a native plant - had stealthily climbed up the trunk. To their surprise, the young participants had mistaken the trailing vines for branches of the tree. This observation highlighted the remarkable ability of poison ivy to adapt to its surroundings, finding innovative ways to persist and thrive in its environment.

As the second group continued their journey down the path, they encountered a Fowler’s toad. Initially, its slippery texture startled them, but they quickly realized the frog's harmless nature. Through gentle pats on its head, they gained a newfound appreciation for these fascinating creatures, transforming their initial fear into a sense of wonder and respect.

Venturing through the marshland, the young explorers gained insights into wetland delineation. They witnessed the fascinating process of using a hand auger and a Munsell Soil Color Book to identify and understand the unique characteristics of wetland soils. In a delightful exploration of local flora, participants delved into the art of species identification using a specialized field guide. They learned to distinguish invasive plant species from their native counterparts, such as sensitive fern, which they were able to see during a short nature walk on a trail back to the nature center.

In a seemingly unremarkable area of the riverbank, the third group stumbled upon a startling discovery. Amidst the lush vegetation, a highly toxic plant known as poison hemlock flourished. The students were taken aback by its presence in an otherwise ordinary location. They had never encountered such a hazardous plant in their previous studies. The poison hemlock, with its delicate white flowers and feathery leaves, belied its deadly nature. The students were captivated by its beauty, but the instructors cautioned them against touching.

The encounter with poison hemlock and poison ivy served as a valuable lesson for the students. They realized that even in seemingly ordinary places, hidden dangers could lurk. They developed a newfound respect for the power of nature and the importance of exercising caution when exploring unfamiliar environments.

Ending the day, participants from the first group had the privilege of attending a lesson conducted by Wildlife Biologist Mike McGraw. With the assistance of the Nature Center's resident corn snake, Mike introduced the students to the fascinating world of reptiles. Overcoming their initial apprehension towards these slithery creatures, the students discovered that there was much more to snakes than they had previously imagined. Mike dispelled common misconceptions and fears, explaining that snakes are not inherently dangerous creatures but rather play a vital role in maintaining the balance of ecosystems.


The NJDEP Youth Inclusion Initiative began on July 8 and culminated on August 16 with a graduation and NJDEP Career Day where students had the opportunity to meet and discuss career options with various organizations who tabled at the event, including Princeton Hydro.

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.


Protecting Natural Green Infrastructure

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.


Modernizing Zoning to Reflect Environmental Realities

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.


Legal Foundations and Enforcement

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.
