Wetland Restoration Project Wins “Land Ethics” Award of Merit

The Pin Oak Forest Conservation Area, located in a heavily developed area of northern Middlesex County, New Jersey, once suffered from wetland and stream channel degradation, habitat fragmentation, decreased biodiversity due to invasive species, and ecological impairment. The site was viewed as one of only a few large-scale freshwater wetland restoration opportunities remaining in this region of New Jersey. Thus, a dynamic partnership between government agencies, NGOs, and private industry, was formed to steward the property back to life and restore its natural function. Today, at Bowman’s Hill Wildflower Preserve’s 19th Annual Land Ethics Symposium, Middlesex County and the project team were presented with the “Land Ethics Award of Merit” for its remarkable restoration achievements.

“In just a few years, the landscape at Pin Oak has transformed from a degraded, disconnected wetland to a healthy, high-functioning landscape,” said Mark Gallagher, Vice President of Princeton Hydro. “This restoration project exemplifies how a diverse group of public and private entities can work together to identify opportunities, overcome challenges and achieve tremendous success.”

The Pin Oak restoration team includes Middlesex County Office of Parks and Recreation, Woodbridge Township, Woodbridge River Watch, New Jersey Freshwater Wetlands Mitigation Council, GreenTrust Alliance, GreenVest, and Princeton Hydro.

The Pin Oak Forest Conservation Area is a 97-acre tract of open space that contains a large wetland complex at the headwaters of Woodbridge Creek. In 2017, the award-winning restoration project converted over 30 acres of degraded freshwater wetlands, streams and disturbed uplands dominated by invasive species into a species-rich and highly functional headwater wetland complex. The resulting ecosystem provides valuable habitat for wildlife and a nurturing environment for native plants such as pin oak, swamp white oak, marsh hibiscus, and swamp rose. The restored headwater wetland system provides stormwater management, floodplain storage, enhanced groundwater recharge onsite, and surface water flows to Woodbridge Creek, as well as public hiking trails, all benefiting the town of Woodbridge.

The Land Ethics Award recognizes the creative use of native plants in the landscape, sustainable and regenerative design, and ethical land management and construction practices. The recipient is selected by a jury of professionals in the field of design, preservation and conservation, and the award is presented at the Annual Symposium.

Fish Passage Restored on the Paulins Kill

On the Paulins Kill, the 100-year old Columbia Lake Dam has almost been completely removed, and fish passage has been restored!  Since the first cut was executed on the main dam in August, many exciting advances have been made towards restoring the Paulins Kill back to its natural state. Check out the video below, courtesy of the New Jersey Nature Conservancy Volunteer Drone Team. 

Piece by piece, the dam was notched out throughout the fall season and is now completely removed with the exception of the dam apron, the horizontal concrete structure that sits downstream of the dam, and the section of the dam that sits below the riverbed. The part of the dam in the riverbed is now being removed all the way down  to three feet under the ground. The full removal is estimated to be complete by mid-March. In mid-August, the first cut was widened to 80 feet, allowing for better management of high flows during storm events, which had been posing a challenge immediately following the first cut.

In late August, the installation of rock vanes at the Brugler Road Bridge began. Rock vanes are engineered, in-stream structures that help to stabilize a channel while enhancing aquatic habitat and movement.

A generic schematic example of cross vanes, this is not the exact engineering plan for this specific project. Photo courtesy of North Carolina Cooperative Extension.

The rock vanes installed at the Brugler Road Bridge site are cross vanes. Cross vanes consist of a set of boulders angled upstream on a river, with another section of smaller rocks placed upstream. The taller sections of the cross vanes deflect the streamflow away from the banks, decreasing scouring effects. Instead, the flow travels over the rock walls and concentrates down the center of the channel, creating a deep and elongated pool in the middle of the stream.  

Velocities between the notches in the rock vanes were evaluated using a velocity meter in accordance with the design specifications originally proposed. Based on the U.S. Fish and Wildlife Service fish passage design criteria, velocities in the notches could not be greater than 8.25 feet per second. All of the velocity measurements in this rock vane were below the maximum thresholds, ensuring no blockage of fish passage is made through the vanes.

Since the removal of the dam began, vegetative growth from the natural seedbed of the upper impoundment has been observed (see photo below).

In October, scour protection installation commenced at the Warrington Road Bridge site. After the team conducted geotechnical test pits, they discovered that a concrete scour wall that slopes out to the Paulins Kill was present and deep enough to be able to install rock at the necessary depth. They also found that the existing gabions, caged baskets filled with rock or concrete often used to protect against erosion, were intact and could be left in place. The team installed four (4) feet of riprap under and around the bridge in the riverbed and tied it into the existing grade of the banks.

The original notch in the dam was lowered one foot per day starting in mid-December, reducing water surface elevations down to the apron elevation during the month of January.

To accommodate NJ Fish and Wildlife’s request for animal passage under the I-80 bridges, an area of the previously installed riprap on the northwest abutment wall was flattened out and filled in with river cobble. This path will promote wildlife movement under the bridge as opposed to through the existing tunnel.

Currently, rock vanes are being installed under the I-80 bridges specifically to enhance fish passage. These structures vary slightly from the rock vanes at the Brugler Road Bridge site, as they are designed to slow river flow, helping migrating fish travel upstream and traverse a 5-foot elevation difference in the streambed, much like a fish ladder

These rock vanes are more than halfway completed and are on track to be finished in time for fish populations to make full use of them.  The next steps are to finish the demolition of the dam and the construction of the fish passage rock vanes under the I-80 bridges, plant vegetation throughout the upper impoundment, create a recreational trail through the upper impoundment, and plan for fishing and boating access! Stay tuned for more exciting developments on this incredible project.

NJ SPOTLIGHT OP/ED Addresses the Creation of Stormwater Utilities in New Jersey

NJ Spotlight recently published an Op/Ed piece co-authored by Association of New Jersey Environmental Commissions (ANJEC) Board of Trustees members John A. Thonet, P.E., P.P., and Dr. Stephen J. Souza, PhD.

The piece asserts the position that New Jersey needs stormwater utilities to provide a sustained source of local funding in order to improve and maintain stormwater infrastructure in communities throughout the state.

We’ve included an excerpt from the Op/Ed below:

NJ SPOTLIGHT OP-ED: NEW UTILITIES WOULD HELP NEW JERSEY FIGHT FLOODING AND POLLUTION

2018 will be one of the wettest years on record for the Garden State, and all that rain has resulted in frequent flooding, millions of dollars in damages, gridlocked traffic, impacted drinking water and polluted waterways.

The problem is daunting, but there is a solution. For decades, the state has provided comprehensive planning and regulations aimed at protecting the public from the flooding impacts of improperly and inadequately managed stormwater. These efforts have helped but failed to address all the social, economic and environmental impacts associated with stormwater runoff. Today, rather than continuing to use conventional “collect, detain and discharge” approaches to controlling runoff, the use of “green infrastructure” is proving to be a better alternative. It’s focused on reducing runoff at its source, through recharge, reuse and evapotranspiration, rather than just treating it as a “waste” or “nuisance” to get rid of as quickly as possible.

Green infrastructure measures include porous pavement, green roofs, rain barrels, rain gardens, bioretention basins and other techniques designed to capture rainwater and allow it to soak into the ground instead of concentrating and discharging it downstream. Additionally, the “green infrastructure” approach is far more attractive and provides ecological and community benefits that can’t be achieved with standard detention basins.

So, what’s the hold-up? The answer is the absence of a sustained source of local funding to implement and maintain new stormwater infrastructure, including green infrastructure, as well as to retrofit, upgrade or replace failing existing stormwater management facilities…

Part Two: Reducing Flood Risk in Moodna Creek Watershed

This two-part blog series showcases our work in the Moodna Creek Watershed in order to explore common methodologies used to estimate flood risk, develop a flood management strategy, and reduce flooding.

Welcome to Part Two: Flood Risk Reduction and Stormwater Management in the Moodna Creek Watershed

As we laid out in Part One of this blog series, the Moodna Creek Watershed, which covers 180 square miles of eastern Orange County, New York, has seen population growth in recent years and has experienced significant flooding from extreme weather events like Hurricane Irene, Tropical Storm Lee, and Hurricane Sandy. Reports indicate that the Moodna Creek Watershed’s flood risk will likely increase as time passes.

Understanding the existing and anticipated conditions for flooding within a watershed is a critical step to reducing risk. Our analysis revealed that flood risk in the Lower Moodna is predominantly driven by high-velocity flows that cause erosion, scouring, and damage to in-stream structures. The second cause of risk is back-flooding due to naturally formed and man-made constrictions within the channel. Other factors that have influenced flood risk within the watershed, include development within the floodplain and poor stormwater management.

Now, let’s take a closer look at a few of the strategies that we recommended for the Lower Moodna Watershed to address these issues and reduce current and future flood risk:

Stormwater Management

Stormwater is the runoff or excess water caused by precipitation such as rainwater or snowmelt. In urban areas, it flows over sewer gates which often drain into a lake or river. In natural landscapes, plants absorb and utilize stormwater, with the excess draining into local waterways.  In developed areas, like the Moodna Creek watershed, challenges arise from high volumes of uncontrolled stormwater runoff. The result is more water in streams and rivers in a shorter amount of time, producing higher peak flows and contributing to flooding issues.

Pollutant loading is also a major issue with uncontrolled stormwater runoff. Population growth and development are major contributors to the amount of pollutants in runoff as well as the volume and rate of runoff. Together, they can cause changes in hydrology and water quality that result in habitat loss, increased flooding, decreased aquatic biological diversity, and increased sedimentation and erosion.

To reduce flood hazards within the watershed, stormwater management is a primary focus and critical first step of the Moodna Creek Watershed Management Plan. The recommended stormwater improvement strategies include:

  • Minimizing the amount of impervious area within the watershed for new development, and replacing existing impervious surfaces with planter boxes, rain gardens and porous pavement.
  • Utilizing low-impact design measures like bioretention basins and constructed-wetland systems that mimic the role of natural wetlands by temporarily detaining and filtering stormwater.
  • Ensuring the long-term protection and viability of the watershed’s natural wetlands.

The project team recommended that stormwater management be required for all projects and that building regulations ensure development does not change the quantity, quality, or timing of run-off from any parcel within the watershed. Recommendations also stressed the importance of stormwater management ordinances focusing on future flood risk as well as addressing the existing flooding issues.

Floodplain Storage

Floodplains are the low-lying areas of land where floodwater periodically spreads when a river or stream overtops its banks. The floodplain provides a valuable function by storing floodwaters, buffering the effect of peak runoff, lessening erosion, and capturing nutrient-laden sediment.

Communities, like the Moodna Creek watershed, can reduce flooding by rehabilitating water conveyance channels to slow down the flow, increasing floodplain storage in order to intercept rainwater closer to where it falls, and creating floodplain benches to store flood water conveyed in the channel.  Increasing floodplain storage can be an approach that mimics and enhances the natural functions of the system.

One of the major causes of flooding along the Lower Moodna was the channel’s inability to maintain and hold high volumes of water caused by rain events. During a significant rain event, the Lower Moodna channel tends to swell, and water spills over its banks and into the community causing flooding. One way to resolve this issue is by changing the grading and increasing the size and depth of the floodplain in certain areas to safely store and infiltrate floodwater. The project team identified several additional opportunities to increase floodplain storage throughout the watershed.

One of the primary areas of opportunity was the Storm King Golf Club project site (above). The team analyzed the topography of the golf course to see if directing flow onto the greens would alter the extent and reach of the floodplain thus reducing the potential for flooding along the roadways and properties in the adjacent neighborhoods. Based on LiDAR data, it was estimated that the alteration of 27 acres could increase floodplain storage by 130.5 acre-feet, which is equivalent to approximately 42.5 million gallons per event.

Land Preservation & Critical Environmental Area Designation

For areas where land preservation is not a financially viable option, but the land is undeveloped, prone to flooding, and offers ecological value that would be impacted by development, the project team recommended a potential Critical Environmental Area (CEA) designation. A CEA designation does not protect land in perpetuity from development, but would trigger environmental reviews for proposed development under the NY State Quality Environmental Review Act. And, the designation provides an additional layer of scrutiny on projects to ensure they will not exacerbate flooding within the watershed or result in an unintentional increase in risk to existing properties and infrastructure.

Conserved riparian areas also generate a range of ecosystem services, in addition to the hazard mitigation benefits they provide. Protected forests, wetlands, and grasslands along rivers and streams can improve water quality, provide habitat to many species, and offer a wide range of recreational opportunities. Given the co-benefits that protected lands provide, there is growing interest in floodplain conservation as a flood damage reduction strategy.


These are just a few of the flood risk reduction strategies we recommended for the Lower Moodna Creek watershed. For a more in-depth look at the proposed flood mitigation strategies and techniques, download a free copy of our Moodna Creek Watershed and Flood Mitigation Assessment presentation.

Conservation Spotlight: Reducing Flood Risk and Restoring Wetlands in Jamaica Bay

Located in Queens, New York on the northern shore of Jamaica Bay, Spring Creek South contains approximately 237 acres of undeveloped land, including wetlands and 2.4 miles of coastline. The site is bounded by the Howard Beach residential neighborhood in Queens, a commercial area along Cross Bay Boulevard, the Belt Parkway, and Jamaica Bay. The northwest section of Spring Creek South is part of the National Park Service’s Gateway National Recreation Area, and is largely comprised of small patches of degraded tidal marsh and disturbed and degraded upland ecosystems.

On October 29, 2012, Hurricane Sandy drove a catastrophic storm surge into the New Jersey and New York coastlines. Spring Creek South and the surrounding community of Howard Beach experienced record flooding and damage to property and critical infrastructure. Storm tides caused damage and erosion along the shoreline and in the salt marsh area, degrading important habitat and leaving the site vulnerable to invasive species.

Hurricane Sandy Aftermath at Howard Beach, taken 10/30/2012 by Pam Andrade

The New York State Division of Homeland Security and Emergency Services (NYSDHSES) was awarded funding from FEMA’s Hazard Mitigation Grant Program to restore Spring Creek South. The U.S. Army Corps of Engineers (USACE) New York District, serving as project administrator, contracted Princeton Hydro to provide ecosystem restoration services. The goal of the project is to reduce future flood risk exposure while also protecting, restoring, and improving the quality and function of ecological systems; improving stormwater management and water quality; and enhancing the park’s visitor experience.

To achieve this goal, the project team is using an integrated approach that involves utilizing green infrastructure to create a natural barrier for the community and reduce the risks of coastal storms. Project activities include berm construction and the restoration of tidal marsh, creation of freshwater wetland forest, and creation of maritime shrub, forest, and grassland habitats, as well as stabilization of the existing shoreline.

On December 31, 2018, we completed Phase One of the project, which entails engineering design and preliminary permitting. More specifically, we’ve provided conceptual planning; analysis of subsurface soils for geotechnical properties and hazardous waste; coastal and freshwater wetland delineations; biological benchmarking analysis; and the development of sea level rise curves and two-dimensional hydrologic and hydraulic coastal modeling. As part of the hydrology study, we analyzed what the site could be expected to look like in 50 years due to climate changes and sea level rise. Our engineering design was also brought to 65% completion.

We also obtained permits, prepared the Environmental Assessment (EA), and oversaw the National Environmental Policy Act (NEPA) process. The EA received a “Finding of No Significant Impact” (FONSI) from FEMA, which means the environmental analysis and interagency review concluded that the project has no significant impacts on the quality of the environment.

Due to the complex nature of this project and its location, we are coordinating with a variety of different entities, including the local Howard Beach Community Board, the FAA (proximity to JFK International Airport), Port Authority, USACE, NOAA Fisheries, USFWS, USEPA, NYSDEC, NYC DEP, the National Park Service, HDR Engineering and WSP Engineering.

Phase Two of the project is the construction phase, which is expected to take about two years to complete. A key part of the Spring Creek South construction activities is the restoration of approximately 40 acres of tidal marsh, which is anticipated to improve water quality locally by stabilizing sediment, reducing erosion, and filtering dissolved particulate materials. The project team will restore existing coastline areas and install a salt marsh along the shoreline. Planted with native flora, like Spartina alterniflora, a perennial deciduous grass found in intertidal wetlands, the coastal salt marsh will help to stabilize sediment. Additionally, removing invasive species like Phragmites australis from the area and replacing it with native plant species will increase the ability for native vegetation to colonize the site, improve vegetative diversity, and reduce fire risk in the park.

A forested wetland area and berm will also be created in order to provide the surrounding communities with natural shields and buffers to future storms. The berm, with an elevation of 19 feet (NAVD88), will help to manage the risk of storm surge flooding caused by coastal storms. The forested wetland area will also provide improved stormwater runoff storage, naturally filter stormwater, and, via flap gates, direct its flow toward Jamaica Bay, away from residential and commercial properties.

These measures will help to dissipate wind and wave energy, increase shoreline resilience, improve stormwater management at the site, and create habitat that increases the ecological value and biodiversity at the site, while providing resilience benefits. Restoration activities will benefit vulnerable and rare ecological communities by producing localized environmental enhancements, including improving water quality and creating and restoring habitat. The project also increases opportunities for recreational uses such as wildlife viewing/photography, fishing, and nature study.

Our D.C. Regional Office is Moving!

New year, new office! Next week, our D.C. Regional office is moving from its current location in Annapolis, Maryland to a new office space just 14 miles away in Bowie, Maryland. We are excited for a change of scenery and the opportunity to grow our space. 

“We are very excited to relocate our office to Bowie, Maryland. This move will continue to increase our presence in Maryland, provide centralized access to our clients, and create new opportunities for the DC/Baltimore region,” said Princeton Hydro President, Geoffrey Goll, PE.

The new space is located between Annapolis, MD and Washington DC, only a 15-minute drive to both cities. This new spot will help us further strengthen our relationships in Washington, DC and with Prince George’s County.

Our new address is 4201 Northview Drive, Suite 314, Bowie, MD 20716.

Employee Spotlight: Helping Communities Around the World Access Water Resources

We’re Proud to Put the Spotlight on Natalie Rodrigues, Staff Engineer And Engineers Without Borders Co-President

As a staff engineer specializing in water resources, Natalie Rodrigues, EIT, CPESC-IT works on a wide range of projects from stormwater management to ecosystem restoration to dam safety. Outside of the office, Natalie is an active volunteer with Engineers Without Borders (EWB), a nonprofit organization that works to build a better world through engineering projects that aid communities in meeting their basic needs.

EWB volunteers work with communities in the U.S. and throughout the world to find appropriate solutions for their infrastructure needs, including clean water supply; sanitation; sustainable energy; structures like bridges and buildings; and various agriculture essentials from irrigation systems to harvest processing.  Natalie began volunteering for the organization six years ago while attending college at the SUNY College of Environmental Science and Forestry where she earned her Bachelor of Science in Environmental Resources Engineering with a focus in water resources.

Her first big volunteer project, which was done in collaboration with EWB’s Syracuse Professionals Chapter, was designing and building a system of composting latrines for an elementary school in the small town of Las Majadas, Guatemala. Natalie provided assistance on several aspects of the project, including working on a Health and Safety Plan. The completion of this project helped to prevent the spread of disease, as well as treat waste without the need for a constant water supply/sewer system. The long-lasting design also increases the health practices and hygiene of the community, creating a safer place for education.

Natalie also served as secretary of the university’s EWB chapter for two years, then became the Regional Administrator for the Northeast Regional Committee, and is now starting her third year as a Co-President of the region.

In her current role with the regional committee, Natalie helps to provide resources for members and facilitates communication between EWB Headquarters and individual chapters. She assists with various mini-conferences and workshops throughout the region and provides opportunities for members to obtain Professional Development Hours and certifications. She is also a part of the EWB’s Diversity and Inclusion Task Force and the Council of Regional Presidents.

We’re so proud to have Natalie on our team and truly value the work she does inside and outside the office.

Barnegat “Clean Water, Beautiful Bay” Project wins Governor’s Environmental Excellence Award

The American Littoral Society was awarded the Governor’s Environmental Excellence Award in the Water Resources category this year for their Clean Water, Beautiful Bay projects in Barnegat Bay.

According to the Barnegat Bay Partnership, over 33% of the Barnegat Bay watershed has been altered to urban land cover. The construction of communities, roads and business has greatly increased the total amount of impervious surfaces in the watershed. With the added impervious cover has come a steady increase in the amount of nutrients, sediment, pathogens and other contaminants transported into the Bay by runoff. This accelerated the degradation of the Bay’s water quality and triggered changes to the Bay’s ecology.

Recognizing the importance of the Barnegat Bay, the American Littoral Society proposed green infrastructure measures to decrease runoff volume and nutrient loading to the bay and its tributaries.  Princeton Hydro was contracted by American Littoral Society to design four projects and provide oversight on the construction of the bioretention basins, rain gardens, porous pavement, etc. The projects were funded by the largest 319 grant ever administered by the NJDEP, totaling around $1 million. The project aimed to:

  1. Improve the water quality of Barnegat Bay by reducing the influx of nitrogen and other pollutants originating from the Long Swamp Creek and Lower Toms River watersheds. And, therefore, improve the water quality of both Long Swamp Creek and Lower Toms River, thus moving them closer to removal from the NJDEP’s 303D list of impaired waters.
  2. Demonstrate that relatively low-cost, stormwater system retrofits are capable of decreasing runoff volume, increasing stormwater recharge, and removing nutrients, and can be effectively implemented in even highly developed watersheds.
  3. Educate the public, elected and appointed officials and public work personnel of the types and benefits of bioretention, biodetention and infiltration stormwater management techniques.

From our team, Dr. Steve Souza and Paul Cooper worked to develop a unique Scoring Matrix for the selection of best management practices for retrofit projects. They have been asked several times to present on the matrix and demonstrate how to beneficially utilize it. In addition to design, Princeton Hydro participated in much of the public outreach for these projects, including giving presentations, leading workshops, and helping high school students plant vegetation around their school.

According to NJDEP, the Clean Water, Beautiful Bay projects were successful in reducing flooding in a private residential homeowner community, improving a stormwater basin and public open space area at a hospital, introducing golf course staff and golfers to environmentally friendly golf course management practices, and engaging high school students in planting projects on school property.  The projects demonstrated that green infrastructure construction projects can reduce flooding and water pollution at business, community, school and public recreation locations, and can be publicly accepted and valued for the environmentally protective and restorative benefits they provide to Barnegat Bay.

Last year, the American Littoral Society’s Barnegat Bay Green Infrastructure Project was named “Project of the Year” by The American Society of Civil Engineers Central Jersey Branch.
