Within the intricate network of aquatic ecosystems, the American shad stands as a captivating enigma. This intrigue was recently explored in a webinar hosted by The Watershed Institute titled “The Mysterious World of the American Shad and Work to Bring Them Back to Our Waterways.” Led by The Watershed Institute’s Executive Director Jim Waltman and Princeton Hydro’s Senior Technical Director in Engineering and American shad expert Dr. Clay Emerson PE, CFM, the webinar explored the complex dynamics surrounding this iconic species, including its historical significance, unique migration patterns, and conservation efforts.

As the American shad embark on their annual upstream journey for spawning, the timing is especially poignant for a closer examination of this vital species and an exploration of strategies to safeguard and revive their populations. We invite you to enjoy our blog, which encapsulates the webinar's key insights, and to watch the full recorded session made available by The Watershed Institute.


Fascinating Facts about American Shad

[caption id="attachment_14758" align="alignright" width="317"] The American shad spawning cycle and migration patterns illustrated by Delaware River Basin Commission[/caption]

American shad (Alosa sapidissima) are the largest members of the herring family. Their closest relatives are herring, sardines, and menhadens. They are an anadromous fish species, like salmon and steelhead (Oncorhynchus mykiss), that live most of their life in the ocean and migrate to freshwater rivers and streams to spawn. The American shad migration routes span vast distances, from the St. Johns River in Florida to the St. Lawrence River in Quebec, showcasing their tenacity and adaptability.

Not only do American shad undertake astonishingly long journeys to spawn, they also showcase distinctive migratory behaviors. Unlike many other anadromous species, these resilient shad can complete multiple round trips from freshwater to the ocean over their lifespan, challenging the conventional notion of 'one and done' spawning observed in Pacific salmon (Oncorhynchus) and sea lamprey (Petromyzon marinus).

Young shad will remain in the rivers where they hatched for several months. Migration out to the ocean typically occurs in late summer in the south, and early fall in the north, typically when the shad are 3-4 inches in size. Then, after 3-6 years of growth at sea, the shad migrate back to fresh water to spawn. Some shad make the journey to their spawning grounds 5-6 times over the course of their lifetime. Shad’s affinity for their birthplace adds a fascinating layer to their story. Approximately 95% of shad return to the rivers where they were hatched, with only 5% straying to unfamiliar waters to spawn.

American shad's unique hearing abilities are another noteworthy aspect. Endowed with specific biological features, shad exhibit exceptional sensitivity to water movements and noise, particularly attuned to sounds like clicks and echolocation. This acute sense plays a vital role in navigating their environment and evading predators such as dolphins.

Such intriguing characteristics make the American shad not only a vital component of aquatic ecosystems but also a subject of admiration and study among enthusiasts and conservationists alike.


Historical Significance

Throughout history, American shad have held a vital place in the cultural heritage and economic prosperity of the United States, earning them the esteemed title of "America's Founding Fish.” Within the Delaware River region, these fish were not merely sustenance but also integral to the fabric of indigenous Lenape culture. During the annual shad migration, rivers and streams overflowing with these prized fish provided essential nourishment and served as valuable fertilizer. Interestingly, in various Native American tribes, folklore depicts the shad as originating from the porcupine, likely owing to the fish's notably bony structure.

In later American history, the significance of shad persisted. Renowned painter Thomas Eakins immortalized the tradition of shad fishing in his iconic 1881 masterpiece "Shad Fishing at Gloucester on the Delaware River," while the state of Connecticut elevated the shad to the status of state fish, further cementing its place in American heritage.

[caption id="attachment_14771" align="aligncenter" width="1162"] This 1871 illustration from Granger Historical Archive depicts fishermen hauling nets of shad at Gloucester on the Delaware River.[/caption]  

Fishing for American shad was among the earliest established industries on the coast of North America, once providing abundant and affordable nutrition to the populace. However, the shad population peaked in the 1940s before experiencing a dramatic decline to its current depleted state.

Despite these challenges, the American shad perseveres as a symbol of resilience. Festivals along the Atlantic Coast, such as the Annual ShadFest in Lambertville, New Jersey, celebrate these fish while also advocating for their protection. Recognizing the historical importance of shad underscores the pressing responsibility to safeguard and preserve our natural heritage for future generations.


Challenges in American Shad Restoration

[caption id="attachment_14759" align="alignright" width="347"] An American shad swimming and feeding in the Delaware River[/caption]

The construction of dams, historic overfishing, and pollution have all played significant roles in the decline of American shad populations.

Dams along the East Coast block access to vital spawning grounds. Currently, a staggering 40% of American shad habitat is obstructed by these barriers, resulting in the loss of more than a third of the population. By removing outdated dams that have outlived their usefulness, we not only improve water quality and natural habitat for myriad species but also reconnect shad to their historic spawning grounds.

Additionally, shad fall victim to inadvertent bycatch in various ocean fisheries. Pollution in our rivers and water quality issues emerge as another critical concern along with fluctuating water temperatures and dissolved oxygen levels that disrupt shad behavior and crucial life cycle events such as migration and spawning. Compounding these issues are the menacing presence of invasive species, which outpace shad in numbers and deplete food resources, posing a significant obstacle to their recovery efforts.

Amidst these challenges, there is hope. River restoration efforts, dam removals, and fish passage projects throughout the East Coast stand as beacons of progress.


Conservation Efforts

Removing obsolete dams, culverts, and other man-made barriers; the implementation of fish passage projects; and river habitat restoration initiatives have shown promising results in directly aiding shad and other migratory aquatic species populations. Highlighted below are a few examples of dam removal initiatives that immediately yielded positive results:

Paulins Kill River

The Nature Conservancy in New Jersey and Princeton Hydro are leading the removal of three outdated dams on the Paulins Kill River: the Columbia Lake Main and Remnant Dams (completed 2019), the County Line Dam (completed 2021), and Paulina Dam (slated for completion 2024). This collaborative effort will reconnect 45 miles of mainstream and tributaries for migratory fish species like American shad. The Columbia Lake Dam removal, New Jersey's largest to date, began in July 2018 and showed promising results even before 100% completion. By April 2019, American shad were spotted 10 miles upstream from the former dam site for the first time in over a century, showcasing the resilience of this incredible species and the success of conservation initiatives.


Musconetcong River

[caption id="attachment_11894" align="aligncenter" width="1720"] Photos by MWA[/caption]  

In November 2016, the Musconetcong Watershed Association (MWA) and Princeton Hydro completed the Hughesville Dam Removal, opening up six miles of the Musconetcong to migratory fish. In the Spring of 2017, schools of American shad were observed above the dam, five miles from the river's confluence with the Delaware River. After an absence of over 250 years, American shad made a triumphant return to the Musconetcong River sparking hope for the future.


Shad serve as a crucial benchmark species, offering valuable insights into the ecological health and diversity of our waterways. Conservation endeavors that facilitate the resurgence of the American shad not only represent a thrilling triumph but also stand as proof-positive of our capacity to assist migratory fish in reclaiming their natural habitats. In doing so, we safeguard their future and preserve the places they call home.

By understanding the biology, historical significance, and primary challenges of the American shad, we can work towards sustainable solutions that benefit both shad populations and the broader ecosystem.

Nestled within the New Jersey townships of Hamilton, Robbinsville, and West Windsor lies Miry Run Dam Site 21—an expansive 279-acre parcel with a rich history dating back to its acquisition by Mercer County in the late 1970s. Originally earmarked for flood mitigation and recreation, this hidden gem is on the cusp of a remarkable transformation, poised to unveil its true potential as a thriving public park.

Central to the revitalization efforts is a comprehensive Master Plan, meticulously crafted by Mercer County Park Commission in partnership with Simone Collins Landscape Architecture and Princeton Hydro. This visionary roadmap encompasses a spectrum of engineering and ecological uplift initiatives, including:

  • Several types of trails and boardwalks that total approximately 7 miles, including a tree canopy walk-through over an area of vernal pools;
  • A nature-based playground and an ADA inclusive playground;
  • Kayak launch and water trail;
  • Protected swimming area for a limited number of swimmers each day;
  • A native plant arboretum and horticultural garden;
  • Fishing access areas;
  • Parking lots, driveways, small restrooms and pavilions; and
  • A group camping area that would accommodate about 30-40 campers.

The Master Plan serves as a long-term vision for improvements to the property and will be implemented over multiple phases. In 2021, it was recognized with the Landscape Architectural Chapter Award from the New Jersey Chapter American Society of Landscape Architects, which underscores its innovative and impactful approach to landscape design.


Phase One is Underway

Now, Dam Site 21’s revitalization has begun with a crucial endeavor: the dredging of its 50-acre lake. This process, spearheaded by Mercer County Park Commission in collaboration with Princeton Hydro, aims to rejuvenate the water body by removing accumulated debris, sediment, and invasive vegetation—a vital step towards restoring its ecological balance. Beyond the aesthetic and ecological improvements, dredging enhances accessibility for recreational activities that provide an opportunity to create a deeper connection between the park’s visitors and its beautiful natural landscape.

Based on the bathymetric assessment, which the Princeton Hydro team completed as part of the Master Plan, the dredging efforts are focused on three primary areas: Area 1 is located in the main body of the lake just downstream of Line Road and will generate approximately 34,000 cubic yards of dredged material; Area 2, which has approximately 4,900 cubic yards of accumulated sediment is located in the northeast cove, just north of Area 1; and Area 3, the northwestern cove, entails the removal of approximately 7,300 cubic yards of accumulated sediment.

The Brooklyn Bridge, a symbol of architectural excellence, spans the East River, connecting the vibrant boroughs of Manhattan and Brooklyn. Beyond its iconic presence, the construction of this masterpiece has a surprising connection to our firm. The roots of the Princeton Hydro headquarters building stretch back to the late 1800s; the first occupants of the building played a pivotal role in manufacturing and supplying the sturdy steel cables that formed the bridge's suspension system, an integral part of its enduring strength. Exploring the building's rich past, we discover a remarkable link to a legendary figure, bridging our current aspirations with the legacy of a woman who left an enduring mark on history.

The Roebling Complex

The John A. Roebling's Sons Company was a wire rope manufacturing facility in Saxonburg, Pennsylvania founded in 1841. In 1848, the company relocated to Trenton, NJ along the Delaware & Raritan Canal and built a 25-acre complex of industrial buildings and facilities for wire rope manufacturing. This included the Carpenter's Shop (Building 110), the building that is now home to the Princeton Hydro's headquarters office, which manufactured specialty wooden products for the operation. The company quickly established itself as a notable employer in the city.

[gallery link="none" columns="2" ids="7920,14703"]

The company gained international recognition for its expertise in wire, wire rope manufacturing, and bridge building. Additionally, their products were extensively utilized in various industries, commercial sectors, and consumer goods. Over 112 years, four generations of the Roebling family successfully managed the business, a remarkable and uncommon accomplishment in the corporate world.

John A. Roebling, the company's founder, was renowned for inventing the wire rope, which revolutionized the way we build bridges. The wire rope (or steel cable) was innovative as it replaced the bulkier and weaker hemp fiber rope that was used to haul canal boats. He also developed a technique for spinning cables in place rather than constructing pre-fabricated cables that required maintenance before actually being used. This enabled him to become the world's foremost builder of suspension bridges in the 19th century, and his bridges spanned major rivers despite skeptics who believed such feats were impossible.


Building the Brooklyn Bridge

The Brooklyn Bridge construction started with an accident when the chief designer, John A. Roebling, had his foot injured by a ferry. He died of tetanus, and his son, Washington A. Roebling, who worked with his father on the Roebling Suspension Bridge over the Ohio River at Cincinnati and on the design of the Brooklyn Bridge, took over the project. Three years into construction of the longest suspension bridge in the world (at that time), Washington was incapacitated by "caisson disease." His wife, Emily Warren Roebling, took over and guided the completion of the bridge, which was one of the 19th century's most impressive architectural achievements. In honor of Women's History Month, we are spotlighting Emily Warren Roebling, whose groundbreaking contributions serve as an inspiring testament to the capabilities and achievements of women in history.

While Washington is widely credited for completing the Brooklyn Bridge in 1883, it's essential to equally acknowledge Emily's significant contributions. Her remarkable leadership, engineering acumen, and tireless dedication were pivotal in navigating the complexities of the Brooklyn Bridge's construction, ensuring its successful completion and solidifying her legacy as an engineering pioneer.

In his book "The Great Bridge," historian David McCullough describes Emily's multifaceted role as both a nurse and private secretary to her husband, taking over his correspondence and record-keeping. Additionally, she actively engaged in the bridge's construction, reviewing plans, visiting the site, and interacting with contractors and bridge officials. McCullough aptly summarized her contributions, stating that she served as "his eyes, his legs, his good right arm."

However, Emily's dedicated support also led to false rumors that her husband, Washington, had lost his mental faculties. Despite these challenges, Emily successfully fought to prevent Washington's removal as chief engineer nearing the bridge's completion. Washington, in turn, acknowledged his wife's invaluable contributions to the project. He later expressed his gratitude, acknowledging her as a "strong tower" and a wise counselor who supported him during difficult times.


Beyond the Brooklyn Bridge

Emily Warren Roebling's advocacy extended beyond her work on the Brooklyn Bridge with her husband.  A pioneering figure of the early 20th century, Emily championed women's equality in education, ownership rights, legal matters, and philanthropic endeavors. She actively participated in women's clubs, contributed to the World's Columbian Exposition, and was nominated for the presidency of the Daughters of the American Revolution.

Her written papers addressed crucial topics such as philanthropy, settlement houses, and the importance of legal education for women. Her legacy continues to inspire, as a new generation of professional women, including lawyers and engineers, joined the suffrage movement after her demise in 1903. It is speculated that had she lived longer, she would have been a prominent leader in the women's suffrage movement. While her direct contributions remain unknown, the sight of female engineers proudly asserting their rights during rallies in academic attire would likely have brought a smile to her face. Emily's advocacy serves as a testament to the enduring power of equality, as subsequent generations of professional women carried her vision forward.


In our dynamic business landscape, we find inspiration in the tale of an extraordinary woman whose vision and tenacity shaped history. Her legacy reminds us that genuine success goes beyond material gains. It lies in the positive influence we leave on the world. Let us all strive to leave a lasting mark that echoes the timeless principles of integrity, resilience, and inclusivity.

In recognition of World Water Day on March 22, it's important to acknowledge and explore the challenges affecting our freshwater ecosystems. In this blog post, we explore one of those said challenges: Harmful Algal Blooms (HABs).

HABs, characterized by rapid overgrowths of cyanobacteria, have increasingly drawn attention due to their detrimental effects on water quality and aquatic ecosystems. With the onset of spring, rising temperatures create favorable conditions for cyanobacteria growth, setting the stage for potential bloom occurrences in the months ahead. Over recent summers, lakes and freshwater bodies across the nation have faced closures and health advisories due to HAB outbreaks, underscoring the urgent need to address this issue.

Cyanobacteria, often referred to as blue-green algae, are naturally occurring microorganisms in aquatic environments. However, under specific conditions—such as warm temperatures and nutrient-rich waters—these organisms can proliferate rapidly, forming blooms that pose risks to the health of humans, wildlife and aquatic species, local economies and overall ecological balance.

[gallery link="none" ids="11577,11570,11565"]

The interplay between climate change and HABs is undeniable: Rising temperatures and altered precipitation patterns create favorable conditions for cyanobacteria growth, exacerbating bloom occurrences. The absence of snow cover and early ice melt further accelerates this process, allowing cyanobacteria to flourish earlier in the year. Over the past few summers, lakes and fresh-waterbodies across the nation experienced closures and health advisories as a result of HAB outbreaks, emphasizing the urgency of addressing this issue.

In light of these challenges, proactive measures are crucial for mitigating the impacts of HABs. Early sampling efforts, initiated as early as March or April, enable the detection of cyanobacteria and akinetes, dormant spores that contribute to bloom formation. Additionally, reducing nutrient inputs, particularly phosphorus, into waterways is essential for preventing HABs.

As we reflect on the significance of water resources on World Water Day, it’s imperative to recognize the importance of addressing threats such as HABs. By raising awareness, fostering collaboration, and implementing effective strategies, we can work towards safeguarding the health and sustainability of our freshwater ecosystems.

In this spirit, we invite you to join the conversation at the Harmful Algal Bloom Summit 2024, hosted by the New Jersey Department of Environmental Protection. This virtual seminar, taking place on March 27, is free to attend and offers a platform for stakeholders to exchange insights, discuss best practices, and explore innovative solutions for managing HABs.

This year's Summit, which is titled “Unlocking the Puzzle of Harmful Algal Blooms," includes a keynote address and three educational sessions - "Growth Through Reflection: Lessons Learned," "Innovative Tools and Applications," and "Beyond the Numbers" - each featuring a variety of expert presentations. Princeton Hydro Senior Technical Director of Ecological Services Dr. Fred Lubnow is presenting on "Quantifying Overwintering Cyanobacteria and How They May Impact the Monitoring and Management of HABs."

One of the Marsh Master®'s primary roles is combating invasive and nuisance plant species, including the notorious non-native Phragmites australis, also known as Common Reed. Utilizing its innovative leveling and cutting mechanisms, this powerhouse of a machine efficiently knocks down and chops up sprayed or winter-weakened vegetation. Equipped with two powerful rotary blades, it effortlessly cuts through dense underbrush and tall marsh grasses, effectively controlling invasive weeds and problematic plant growth.

"We are committed to offering more non-chemical alternatives for aquatic invasive species control. The Marsh Master® 2MX-KC-FH is the second marsh buggy in our fleet," said Geoffrey M. Goll, President of Princeton Hydro. "This model is larger and more powerful, allowing us to cover more ground in a shorter period of time. Adding this machine to our fleet is an important investment in achieving our firm's environmental stewardship goals."

What sets the Marsh Master® apart is its versatility and low environmental impact. With its lightweight construction and advanced weight distribution system, it exerts low ground pressure and boasts high floating capacity. This allows the Marsh Master® to operate seamlessly on water, in deep or shallow depths, and on dry land without disturbing sensitive environments like nature preserves, wetlands, and canal banks. Its highly maneuverable design ensures easy passage through narrow channels and around hazards, making it the ideal choice for a wide range of applications.

But the Marsh Master® is not just a one-trick pony. With a wide array of tools and accessories, it can perform a variety of functions, from weed cutting and harvesting to debris removal to excavation to soil sampling.

During a recent project in Middlesex County, we put the Marsh Master® to the test to clear an area overrun with Phragmites australis. These invasive weeds not only create dense thickets unsuitable for native fauna but also outcompete local vegetation, leading to a decrease in plant diversity. Thanks to the Marsh Master®'s efficient cutting and rolling capabilities, we were able to expose the marsh plain and get it ready for planting of native vegetation in the Spring. This is just one example of how the Marsh Master is making a tangible difference in restoring delicate ecosystems.

Restoration Overview and Community Impact

Spanning 47 acres, Lion's Pride Park serves as a green oasis within the Township, offering a range of recreational and educational opportunities for visitors of all ages and abilities.

The pond within the park was in urgent need of restoration - heavy storm events caused the pond to overflow, which created flooding conditions in the park. The local native biodiversity was being threatened by nusiance and invasive species like water chestnut (Trapa natans). The photos below were taken in April 2020.

[gallery link="none" columns="2" size="medium" ids="14485,14486"]  

Princeton Hydro began in 2020 with site investigation and field surveys, including:

  1. Bathymetric assessment to map water depth and accumulated unconsolidated sediment in the pond
  2. Sediment sampling to facilitate options for the potential reuse of the sediment on site and the selection of native vegetation for the various habitats being created
  3. Wetland delineation to identify existing wetland boundaries within and adjacent to the project site and discern the extent of jurisdictional impacts related to the proposed activities.

The most substantial component for the restoration project was the conversion of the existing pond to an emergent wetland complex to provide habitat for a wide variety of native species. Using the completed existing conditions reports and surveys, Princeton Hydro prepared the conceptual design plan that informed the entire restoration process.

Princeton Hydro Regulatory Compliance & Wildlife Surveys Project Manager Emily Bjorhus, PWS spearheaded the regulatory program for the project, navigating approvals from the Pennsylvania Department of Environmental Protection (PADEP), the U.S. Army Corps of Engineers (USACE), and the Bucks County Conservation District. The permitting process laid the groundwork for the smooth implementation of this design-build restoration project.

The restoration work encompassed various stages, from earthwork and vegetation planting to the installation of ADA-compliant pathways and informational signage. Some of the key project elements, include:

Channel stabilization: Stabilizing the channels within the park, addressing erosion issues, enhancing water flow dynamics, and promoting the establishment of diverse aquatic habitats.

Berm construction: Installing berms to enhance wetland habitat and promote natural floodplain connectivity, contributing to the resilience of the ecosystem to flooding events.

Native vegetation planting: Reintroducing native wetland and riparian plant species to enhance biodiversity and create habitat corridors for wildlife within the park. Planting is expected to take place in the Spring.

Interpretive signage installation: Placing educational signage throughout the park to inform visitors about the ecological significance of the restoration project and the importance of wetland conservation.

Boardwalk installation: Constructing a 6-foot-wide ADA-compliant boardwalk that spanned approximately 230 linear feet, providing visitors with accessible pathways to explore the restored wetland areas.

[gallery columns="2" link="none" size="medium" ids="14491,14490,14492,14487"]

Through these strategic interventions, the Lion's Pride Park Ecological Restoration Project aims to not only rejuvenate the ecological integrity of landscape but also enrich the recreational and educational experiences of the community. The project, which is slated for 100% completion this Spring, will totally transform the landscape into a diverse wetland complex that fosters native wildlife habitat, mitigates water quality concerns, reduces nonpoint source pollutants discharged to downstream waters, and provides accessible pathways and observation platforms so all community members may enjoy and learn from this restored aquatic setting.

The reclaimed wetland provides additional bird and pollinator habitat and offer visitors a diverse ecosystem to learn from within the park. By fostering a deeper connection to nature and promoting environmental stewardship, this project exemplifies the transformative power of ecological restoration in creating vibrant, sustainable communities.

New Jersey’s water-related infrastructure is a complex system, constantly facing the challenges posed by stormwater runoff and working to properly manage it. Stormwater management isn’t just about handling rainfall; it’s a critical aspect of preserving water quality and mitigating flooding risks. In New Jersey, where urbanization and rainfall patterns intersect, managing stormwater is more than just a priority; it’s a necessity. Enter a stormwater utility— a dedicated fee to address these stormwater management challenges.

Stormwater Utilities in New Jersey

New Jersey’s stormwater infrastructure (storm drains, sewer piping, etc.) is aging and unable to effectively handle the amount of runoff that has been flowing through the region in recent years. This is causing increased nutrient runoff and flooding in communities throughout the state. With increasing global temperatures and the proliferation of intense storm systems, this trend is likely to continue.

To address these issues, in 2019, New Jersey enacted the Clean Stormwater & Flood Reduction Law that allows municipalities, counties, groups of municipalities, and sewage and improvement authorities to establish a stormwater utility.

For many local leaders, the process to establish a utility can be complex, often depending on a number of details like the scope of the work and size of the community. In 2021, Princeton Hydro teamed up with the New Jersey League of Conservation Voters, New Jersey Future, and Flood Defense New Jersey to host a webinar explaining the purpose of a stormwater utility; how a stormwater utility works; how to decide if a stormwater utility is the right fit for a particular community; and how municipalities or counties can implement one.

In 2022, New Jersey Department of Environmental Protection (NJDEP) announced the availability of Technical Assistance for Stormwater Utility Feasibility Studies, which supports municipalities in completing a stormwater utility feasibility study. Stormwater feasibility studies can help communities weigh the costs and benefits of having a stormwater utility to determine if it's right for them. Princeton Hydro is currently conducting a feasibility study for the City of Lambertville.


Jersey Water Works Stormwater Utility Information Forum

Jersey Water Works is a collaborative effort of many diverse organizations and individuals who embrace the common purpose of transforming New Jersey’s water infrastructure. They bring people together to find equitable solutions focused on: Clean water and waterways; healthier, safer neighborhoods; local jobs; flood and climate resilience; and economic growth. Jersey Water Works consists of many different committees run by volunteers, including the Stormwater Utilities Subcommittee, which is part of the Asset Management and Finance Committee.

The Jersey Waterworks Stormwater Utility Subcommittee launched the “Stormwater Utility Informational Forum” comprising five one-hour-long, town-hall-style education sessions. Each session featured expert panelists who explored various aspects of creating a stormwater utility and establishing a sustainable and dedicated funding mechanism to pay for a community’s stormwater management program.

Utility leaders, government stormwater managers, municipal and county representatives, elected officials, experts and stakeholders came together to discuss the topics of stormwater financial planning and funding options; New Jersey legislation and the utility development process; stormwater rate structures and credits; stormwater utility policies; and stakeholder engagement.

Key leaders in the Stormwater Utility subcommittee who organized the information forum include Dana Patterson Grear, Director of Marketing and Communications for Princeton Hydro (co-chair); Micah Shapiro of RES (co-chair); Prabha Kumar of Black & Veatch Management Consulting LLC; and Elizabeth Treadway of WSP. The forum presenters included Prabha Kumar, Elizabeth Treadway, Dana Patterson Grear, Dave Mason of CDM Smith; Lindsey Sigmund of New Jersey Future.


The Art of Stakeholder Engagement

Prabha Kumar and Dana Patterson Grear led the final session of the forum, which was dedicated to Stakeholder Engagement. They shared their expert recommendations and real-world experience in fostering community involvement, navigating the complexities of stakeholder engagement, and developing inclusive public meetings and dialogues related to implementing a stormwater utility feasibility study.

The presentation emphasized the significance of prioritizing stakeholder engagement early on and maintaining consistent engagement throughout the entire stormwater utility feasibility process. Prabha and Dana also provided tons of easy-to-follow, actionable tips, including:

  • How to structure your stakeholder groups, including the creation of a project team, a project champion and internal steering committee;

  • Which local community groups, municipal entities, and other external stakeholders to include in the conversation and when to include them;

  • Key factors in planning public workshops, like how many workshops to host, should the workshops be virtual or in-person, and how to structure the agenda for the best results; and

  • How to create engaging graphics, solicit feedback and educate the target audience in ways that are inclusive, informative and tailored to the unique characteristics of the community.

"Creating a stormwater utility in your community can be challenging as it is a public policymaking process. Engaging stakeholders throughout the entire process and educating the public is not just a step; it's the cornerstone to success," said Dana. "It's about embracing a  diversity of voices from day one, listening to concerns and ideas, and collaboratively shaping a solution that resonates with your communities' needs."
