Green Infrastructure and Stormwater Utilities: Solutions to NJ’s Environmental Issues

Flooding, runoff, and storm surges, OH MY!

With increases in each of these occurring now, the imposition of green infrastructure and a stormwater utility fee are viable solutions to reducing their impacts. Plus, with the passing of the S-1073/A2694 bill in early 2019, the introduction of a stormwater utility became legal in New Jersey, making it the 41st state to do so.

On June 19, 2019, The Watershed Institute in Pennington, NJ held the “New Jersey Green Infrastructure & Stormwater Utilities Symposium” to address the environmental problems New Jersey faces and present solutions, including the stormwater utility. The event was geared for municipal officials, engineers, nonprofit leaders, and other interested parties, with an agenda full of expert speakers sharing insights and ideas on topics like the science of stormwater, New Jersey’s proposed stormwater rule changes, why green infrastructure and a stormwater utility fee matter, and possibilities for how to move New Jersey forward.

So, What is Green Infrastructure?

Brian Friedlich, the first presenter and a project manager for Kleinfelder, relayed that according to NJDEP, green infrastructure consists of “methods of stormwater management that reduce stormwater volume, flow, or characteristics by allowing the stormwater to infiltrate, be treated by vegetation or by soils, or be stored for use.” He also explained that green infrastructure can improve the environment and communities by providing community engagement, greening communities, addressing flooding, improving water quality by reducing CSOs, harvesting rainwater, increasing habitat for wildlife, and increasing property values.

After Brian’s presentation, a founding Principal of Princeton Hydro, Dr. Stephen Souza, now CEO of Clean Waters Consulting, urged that we should “turn down the volume,” when it comes to stormwater runoff. He explained that it is not enough to just manage peak flow of stormwater; we must also work to lower the volume of off-site stormwater discharge. So, how can you and your municipality do this? He offered six principles to designing successful green infrastructure projects:

  1. Treat stormwater as a resource
  2. Don’t make stormwater management an afterthought
  3. Attack the cause not the symptoms
  4. Turn your watershed inside out
  5. Think small to achieve big results
  6. Use nature as your model

Not only is successful implementation of green infrastructure important, but communal understanding of it may be more so. That is why Princeton Hydro partnered with New Jersey Future, Clark Caton Hintz, Rutgers Cooperative Extension Water Resources Program, FZ Creative, and municipal stakeholders to launch the New Jersey Green Infrastructure Municipal Toolkit. Filled with helpful information about green infrastructure, this free resource is extremely useful for gaining communal understanding, getting started, implementing nature-based stormwater solutions, and sustaining your program.

What is Stormwater and Why Should Municipalities Require a Utility Fee for It?

Before we get into why it is imperative for New Jersey municipalities to implement a stormwater utility fee, it is important to understand just what stormwater is, what it does, and how it affects New Jersey residents.

The name is pretty intuitive: stormwater is the water that comes from precipitation, whether that be rain, snow, or ice melt. With increasing levels of water from climate change impacts (i.e. storm surge, increased rainfall, sea level rise), stormwater management has become an issue for states all across the U.S., whether it’s an over abundance or lack thereof.

So, what’s happening in New Jersey? The stormwater infrastructure that is currently in place (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 all over the state. And, with increasing global temperatures, this trend is likely to continue.

To combat these issues, New Jersey passed the S-1073/A2694 bill in January 2019, authorizing counties and municipalities, either separately or in combination with other municipalities, to begin implementing a stormwater utility fee to New Jersey residents.

The law itself states:

“Every sewerage authority is hereby authorized to charge and collect rents, rates, fees, or other charges for direct or indirect use or services of its stormwater management system. The stormwater service charges may be charged to and collected from the owner or occupant, or both, of any real property. The owner of any real property shall be liable for and shall pay the stormwater service charges to the sewerage authority at the time when and place where these charges are due and payable. The rents, rates, fees, and charges shall be determined in a manner consistent with the stormwater utility guidance manual created by the Department of Environmental Protection pursuant to section 24 of P.L.

Any stormwater service charge imposed pursuant to subsection a. of this section shall be calculated in a manner consistent with the guidance provided in the stormwater utility guidance manual created by the Department of Environmental Protection pursuant to section 24 of P.L.”

Essentially, this fee charges a chosen type of property owner within a given municipality or region a certain amount of money for the impervious area (mainly artificial structures like asphalt, concrete, stone, rooftops, etc. that water can’t seep through) they have on their property. Just how much that fee is and whether or not there’s a limit on the chargeable impermeable area are dependent on the government agency.

Since the impervious area blocks water from seeping into the ground, it becomes runoff and ends up in the stormwater drain. And, since New Jersey’s systems are growing old and less efficient, it makes sense to implement a fee for their use. Historically, general taxpayer dollars or legislative appropriations have been used to fund updates to aging infrastructure. Implementing a utility fee will create a consistent funding source to update and expand the current aging infrastructure so that flooding will occur less.

Other states, like neighboring Pennsylvania, have been proactive in addressing these impacts by implementing a stormwater utility fee. And, in Maryland, the state implemented a watershed restoration program and MS4 efforts that require stormwater utility fees. These initiatives have generated a job-creating industry boom that benefits engineers, contractors, and local DPWs. At the same time, Maryland’s program is improving the water quality in the Chesapeake Bay, and stimulating the tourism and the crabbing/fishing industry.

In relation to how urban cities are affected by stormwater, John Miller, the FEMA Mitigation Liaison, shared this helpful resource, “The Growing Threat of Urban Flooding: A National Challenge” during the symposium. It addresses the extent and consequences of urban flooding in the U.S., while exploring actions that can be taken to mitigate future flooding. Amongst other recommendations made, the research group encouraged Congress and state officials to “develop appropriate mechanisms at the federal, state, and local level to fund necessary repairs, operations, and upgrades of current stormwater and urban flood-related infrastructure.”

A stormwater utility should not only be reviewed in the context of cost, since it meets all three elements of a triple-bottom line: social, environmental, and financial. Other considerations are the fact that allowing stormwater utilities in New Jersey will create jobs, help reduce flood impacts, enhance water quality, improve our fisheries, and preserve our water-based tourism economy.

When it comes to green infrastructure, Princeton Hydro has been a leader in innovative, cost-effective, and environmentally sound stormwater management systems since its inception. Long before the term “green infrastructure” was part of the design community’s lexicon, the firm’s engineers were integrating nature-based stormwater management systems to fulfill such diverse objectives as flood control, water quality protection, and pollutant load reduction. And, Princeton Hydro has developed regional nonpoint source pollutant budgets for over 100 waterways. The preparation of stormwater management plans and design of stormwater management systems for pollutant reduction is an integral part of many of the firm’s projects. So, we are major proponents of implementing stormwater utilities and green infrastructure into our everyday lives.

Deal Lake Commission Wins Award For “Lake Management Success”

NALMS President Dr. Frank Browne with Princeton Hydro Co-Founder Dr. Stephen Souza accepting the “Lake Management Success Stories” award on behalf of the Deal Lake Commission.

The Deal Lake Commission’s success in the management and restoration of Deal Lake garners a prestigious award from the North American Lake Management Society

 

The North American Lake Management Society (NALMS) awarded the Deal Lake Commission (DLC) with its “2018 Lake Management Success Stories” award. The award, which was presented at the NALMS 38th International Symposium, is given annually to recognize and honor an individual or group that has made significant lake/reservoir management accomplishments.

The DLC has overseen the management and restoration of Deal Lake and its watershed since 1974. Consisting of appointees from the seven municipalities abutting the lake, the DLC’s mission is to provide leadership, guidance and resources to preserve and restore Deal Lake and its tributaries as a healthy and stable ecosystem. A true challenge in an urban environment.

“It has been both a pleasure and an honor to work with the Deal Lake Commission for the past 35 years,” said Dr. Stephen Souza, Princeton Hydro Co-Founder. “They have shown great resolve to tackle some serious problems affecting the lake and its watershed, serving as a great example for other organizations involved in the restoration of urban lakes.”

Deal Lake is New Jersey’s largest coastal lake, encompassing 162 acres. The lake is surrounded by a 4,400-acre highly urbanized watershed, with the majority of development dating back to the 1960s-1980s. As a result, stormwater management, particularly with respect to water quality and volume management can be especially challenging. The DLC has embraced the numerous challenges, and has worked diligently over the years to correct these issues.

Restored shoreline at the Asbury Park Boat Launch in Deal LakeAt the forefront, the DLC has been managing the primary cause of the lake’s eutrophication: stormwater runoff from the surrounding watershed. In 2014, with funding provided through the NJDEP’s 319(h) program, the DLC implemented a number of demonstration projects, specifically the construction of three bioretention basins, the installation of a large manufactured treatment device, the vegetative stabilization of over 500 feet of heavily eroded sections of the shoreline, and the construction of a rain garden at the Deal Lake boat launch.

Collectively these projects were shown to eliminate localized flooding, decrease floatable loading, and reduce nutrient, sediment and pathogen inputs to the lake. These and other projects implemented by the DLC over the years show that despite Deal Lake being located in a highly urbanized watershed, it is possible to implement cost-effective green infrastructure and stormwater retrofit solutions.

Deal Lake recently won another very competitive 319 (h) program for $735,000 for MTDs, tree boxes, and Green infrastructure improvements to Deal Lake, Sunset Lake and Wesley Lake.

The NALMS award nomination application, which was submitted by Dr. Souza, listed a number of additional achievements of the DLC, including:

  • Educating the community, including school children, to increase awareness and appreciation for the natural environment of the lake;
  • Sponsoring and conducting public engaged spring and fall cleanups, which annually result in the removal of 1,000s of pounds of refuse and debris from the lake;
  • Helping homeowners and public groups recognize and mindfully solve problems related to water quality, siltation, and lake restoration;
  • Serving as the liaison between lakeside communities, County agencies, and the NJDEP;
  • Microbial source tracking investigations with Monmouth University and pathogen source identification work with Clean Ocean Action to decrease E. coli loading;
  • Carp removal, invasive species management, and goose control initiatives;
  • Working with State legislators to implement stricter stormwater controls to reduce pollutant loading, increase storm resiliency, and improve recreational fishing;
  • Participating in the NALMS Secchi Dip In; and
  • Proactively suggesting and supporting community-based, practical ideas to improve the overall environmental quality of the lake and its enjoyment by boaters, anglers, hikers, residents and visitors.

New Green Infrastructure Toolkit for Municipalities

Our partner, New Jersey Future, just launched a brand new, interactive website toolkit to help municipalities across the state incorporate green infrastructure projects into their communities. The New Jersey Green Infrastructure Municipal Toolkit will provide expert information on planning, implementing, and sustaining green infrastructure to manage stormwaterThis toolkit acts as a one-stop resource for community leaders who want to sustainably manage stormwater, reduce localized flooding, and improve water quality.

According to the United States EPA, a significant amount of rivers, lakes, ponds, bays, and estuaries in New Jersey fall into the “Impaired Waters” category, meaning that one or more of their uses are not being met. This reality makes green infrastructure more important than ever in the effort to protect our waterways. When it rains, stormwater creates runoff, which often carries pollution to various types of waterbodies. Green stormwater infrastructure helps to absorb and filter rainwater, reducing the pollution entering our waterways and mitigating flooding in our communities. In urban areas, green infrastructure utilizes natural vegetation to divert stormwater, creating a cost-effective and aesthetically-pleasing way to manage water during rain events.

“We designed this toolkit to bring to light the benefits and importance of investing in green infrastructure at the local level,” said Dr. Stephen Souza, co-founder of Princeton Hydro. “Since the current NJ stormwater rules do not require green infrastructure, we hope to inspire municipal engineers and planning board members to believe in the value through our toolkit. Additionally, we hope it will serve as an educational resource to local officials and decision makers in the Garden State.”

For this project, Princeton Hydro was contracted by Clarke Caton Hintz, an architecture, design, and planning firm, leading this effort on behalf of the nonprofit organization New Jersey Future. Our expert engineers and scientists provided real-world examples integrating green infrastructure into development, in hopes of showing those using the toolkit real world evidence of how green infrastructure can be a part of the daily lexicon of stormwater management. Additionally, Dr. Stephen Souza developed performance standards that municipalities can integrate into stormwater management plans, which are available in the Green Infrastructure Municipal Toolkit.

How’s the Fishing? Tips for Managing Your Lake’s Fishery

The fishery of a lake is an intrinsic, incredibly dynamic element of a lake system, and managing a lake’s fishery can be a very complex endeavor. There is actually a lot more to it than simply stocking game fish. Although there is no “one way” in fisheries management, there are key guidelines that can be followed to maximize the recreational potential of your lake’s fishery and increase the success of your fishery management and stocking efforts. Over the past two decades, Princeton Hydro has been working with lake, pond, and reservoir managers to help them to align water quality, fishery, and ecological goals.

Princeton Hydro’s Founder, Dr. Steve Souza, recently gave a presentation on fisheries management at the Spring Meeting of the New Jersey Coalition of Lake Associations (NJCOLA). We’ve compiled a few essential elements from his presentation and have made the complete presentation available for free download.

Let’s dive in!

Benefits of a Healthy Fishery

Recreational fishing is an outdoor activity that can be enjoyed by people of all ages. When children are introduced to fishing, it helps cultivate a connection to the environment, thereby promoting outdoor activity and environmental stewardship among today’s youth.

Anglers have always served as important advocates for the conservation of natural resources. The sale of fishing licenses financially supports wildlife habitat conservation and enhancement as well as the protection and improvement of water quality. This increases the ecological services and functions of lakes and adds to their societal and recreational benefits.

A healthy fishery can have significant positive impacts on water quality. In a balanced, healthy fishery the ratio of forage and game fish affects the entire food web, helping to maintain the proper balance of zooplankton and phytoplankton. The “top down” ecological control associated with a balanced fishery minimizes algae blooms, sustains good water clarity and stable water quality. However, when the fishery is out of balance, the water quality and overall ecological health of the lake often suffers.

Before You Stock, Know Your Lake and Start with a Baseline

Before you do any fish stocking, it’s best to conduct a fishery survey. A fishery survey provides the vital data needed to design a stocking and management plan.

A balanced lake fishery is dependent on good water quality, ample habitat, and the correct ratio of predator and prey fish species. A properly designed and implemented fishery survey generates the data needed to quantify the overall composition of the existing fish community (predator vs. prey), the make-up of the forage (food) base, and the density and robustness of the lake’s top piscivores (prized game fish).

The resulting data helps identify if your fishery is balanced, which fish to stock, and how many of each species to introduce. It will also provide the benchmarks needed to solidify your management goals and, later on, help determine if the goals are being met. To stay on track, we recommend that a comprehensive fishery survey be conducted once every three years. Be sure to use the correct types and combination of “active” and “passive” sampling gear and thoroughly sample both the open water and nearshore areas of the lake.

The survey should include the collection and analysis of water quality data, and the mapping of available habitat. Water column water quality “profiles” provide vital information pertaining to the lake’s thermal and dissolved oxygen properties; key factors for a healthy, vibrant fishery. Here are some basic water quality guidelines:

  • Dissolved oxygen: ≥ 4 mg/L with 6-7 mg/L being ideal
  • For warm water fishery: Uniform temperatures at all depth (minimal or no thermal stratification)
  • For cold water fishery: Deep water temperature of 15 C, and dissolved oxygen ≥ 5 mg/L
  • pH: 6 to 8
  • Clarity: ≥ 3 feet (1 meter) Secchi disc transparency
  • Total Phosphorus: < 0.05 mg/L
  • Chlorophyll a: < 20 µg/L

Water quality sampling should also include an assessment of the lake’s zooplankton and phytoplankton communities, the base of your lake’s food web.

Floating Wetland Island

During the survey, take the time to quantify and map the distribution of existing forage, spawning, and refuge habitat. Lack of adequate habitat can significantly impede the fishery’s sustainability. This begins with the bathymetric mapping of the lake, which is basically an underwater survey of the bottom of the lake. This mapping shows where and how much shallow water versus open water habitat exists.  It can also help identify the location and distribution of important habitat types, such as shoals, rock piles, sandy open areas and natural structures (tree falls and snags). The data also helps determine where to create and introduce habitat, which can be in the form of brush piles, floating wetland islands, and other types of features that increase the spawning, recruitment, and foraging success of the fishery.

Stocking Your Lake

Once the fishery survey is completed, habitat is mapped and water quality analyzed, stocking can begin. In order to determine the specific stocking levels and rates that are right for your waterbody, here are some factors to consider:

  • Ensure your stocking efforts create or augment the correct ratio of predator (game) and prey (forage) fish.

  • Stock cautiously, focusing on a simple composition of predator and prey species. For most warm water lakes, largemouth bass should serve as the top predator and fathead minnow should be the primary prey.

  • Avoid problem fish, such as golden shiner, alewife and brown/black bullhead. Although these fish are often promoted as suitable forage species, they can be easily get overstocked and cause major disruptions of the fishery and to the degradation of water quality.

Go here for a more in-depth look at how to properly stock your fishery.

In Summary

A healthy sustainable fishery isn’t only a function of the types and amounts of fish stocked in a lake; it is directly a function of water quality, the availability and quality of spawning, foraging and refuge habitat, the ratio of forage to predator fish, and the overall composition and balance of the food web.

Begin with a fishery survey; the resulting data enables a correctly planned and implemented stocking program. Conduct routine surveys to assess the status of the fishery and the success of the program. Also, annual water quality testing provides the information needed to make wise pro-active fishery management decisions. It will also provide insights into the lake’s environmental conditions to ensure they are supportive of a healthy, productive and sustainable recreational fishery.

“Floating Classroom” Launches into Lake Hopatcong

The Lake Hopatcong Foundation (LHF) recently launched its newest initiative – a floating classroom. The custom-built 40-foot education vessel, named ‘Study Hull’, gives students an interactive, hands-on education experience to explore Lake Hopatcong, learn about freshwater ecology, and learn how to protect the watershed.

During its maiden voyage field trip, which was held on May 21, fourth-graders from Nixon Elementary and Kennedy Elementary schools utilized the boat’s laboratory instruments to study water hydrology, temperatures, plankton, and dissolved oxygen levels. They performed a series of tests and experiments designed to help them learn about the general health of the lake. They used Secchi Disks to determine the depth to which light is able to penetrate the water’s surface. They also learned about runoff and nonpoint source pollutants, how to protect the lake’s water quality, and how to be good stewards of the water.

Princeton Hydro helped the LHF design a teaching curriculum on water quality.  Dr. Jack Szczepanski, Senior Aquatics Scientist, and Christopher L. Mikolajczyk, CLM, Senior Project Scientist, trained the staff and volunteers on the curriculum and demonstrated various water quality monitoring techniques that can be conducted with the students.

“We’re really proud to be a part of this exciting initiative,” said Mikolajczyk. “It’s really important to get kids interested in science at an early age and teach them about their surrounding environment – where their drinking water comes from, how it gets polluted, the impacts pollution has on the lake’s ecosystem, and what steps can be made to protect the lake’s water quality. We’re hoping the floating classroom field trip program will make a lasting, valuable impression with these kids.”

In the first year of operation it is expected that the Study Hull will host 1,000 fourth grade students. The long-term goal is to develop lesson plans for students in every grade from kindergarten through high school. Starting in July, the LHF is also offering the public tours of the floating classroom on Mondays at Hopatcong State Park.

The purchase of the floating classroom was made possible by financial support from USATODAY Network’s “A Community Thrives” program, which awarded the LHF with a $50,000 grant. The program recognizes three categories: arts and culture, education, and wellness. In each category, the first place winner received a $100,000 grant and the second and third place winners received $50,000 grants. The James P. Verhalen Family Foundation and the Szigethy Family also provided significant donations to help bring the floating classroom to life.

 

The LHF and Princeton Hydro are longtime partners. Starting back in 1983, Princeton Hydro’s Dr. Stephen Souza conducted the USEPA funded Diagnostic Feasibility study of the lake and then authored the Lake Hopatcong Restoration Plan. That document continues to be the backbone of why and how to restore the lake, manage the watershed, reduce pollutant loading, and address invasive aquatic plants and nuisance algae blooms.

Lake Hopatcong has one of the longest, continuous, long-term ecological databases in New Jersey; almost 30 years of consistently collected water quality data. The data is crucial in assessing the overall ecological health of the lake and proactively guiding its management, identifying and addressing emerging threats, documenting project success (a mandatory element of funding initiatives) and confirming compliance with New Jersey State Water Quality standards.

Princeton Hydro’s most recent work for Lake Hopatcong includes the implementation of green infrastructure stormwater management measures, installation of floating wetland islands to improve water quality, and invasive aquatic plant species management programs, community educational training, and surveys.

NYSFOLA Awards Dr. Stephen Souza with Highest Honor at 2018 Annual Conference

The New York State Federation of Lake Associations (NYSFOLA) Board of Directors awarded Dr. Stephen Souza, Founder, Princeton Hydro with its ‘Lake Tear of the Clouds’ Award. This award, named after the highest lake in the state, is NYSFOLA’s highest honor. It is only given to a person who has shown the highest dedication to New York’s lakes and watersheds, assisted NYSFOLA in its mission, and produced exceptional performance in his or her field of endeavor.

In bestowing this award to Dr. Souza, NYSFOLA recognizes his accomplishments and efforts in the management and restoration of lakes throughout the State of New York and his support of the initiatives promoted by NYSFOLA. The award was presented at the NYSFOLA’s 35th annual conference, which was held on May 4th and 5th at the Fort William Henry Hotel in Lake George.

During his acceptance speech, Dr. Souza said, “I am truly humbled and appreciative to have even been considered worthy of this award.  In accepting the ‘Lake Tear of Clouds’ Award, I want to extend my deepest thanks to NYSFOLA, the NYSFOLA Board of Directors, Nancy Mueller (NYSFOLA Manager), and all of you here tonight.  It is people like yourselves, who advocate for clean lakes, that have made my career so rewarding. I would be remiss if I also did not take the time to thank my wife Maria and my family for their support over the years and of course the dedicated lake scientists that I have the pleasure to work with day in and day out at Princeton Hydro. That of course includes Dr. Fred Lubnow, who I have had the pleasure of working side-by-side with since 1992, Chris Mikolajczyk and Mike Hartshorne, both of whom are here tonight, and the rest of my Princeton Hydro colleagues.”

Dr. Souza first attended the NYSFOLA conference in 1985, and has been working to assess, restore and protect watersheds throughout the state of New York for over 35 years. Some of the notable projects managed by Dr. Souza over that time include projects conducted at Honeoye Lake, Sodus Bay, Greenwood Lake and Sleepy Hollow Lake. He is currently working with New York State Department of Environmental Conservation on a major statewide harmful algae bloom (HAB) management effort.

“We thank you for your longtime support of NYSFOLA and our member lake association, Steve,” said Nancy J. Mueller, Manager. “And, we congratulate Princeton Hydro on its 20th anniversary.”
