A beautiful rainbow trout at “Jamesburg Lake” in Middlesex County.

     TROUT FISHING ‘OPENING DAY’:  New Jersey’s trout fishing “Opening Day” was Saturday, April 6. On that day, I surveryed anglers as a state Fish and Wildlife volunteer. I was at “Jamesburg Lake,” properly “Lake Manalapan” on the boundary of Jamesburg and Monroe in Middlesex County. County Parks and Recreation lists the lake as 30 acres, created by the damming of Manalapan Brook. Prior to Opening Day, NJ Fish and Wildlife released 610 rainbow trout, “Oncorhynchus mykiss,” into the lake. I interviewed about 50 anglers, who reported catching 65 rainbow trout of which 49 were kept, 7 released, and 9 unknown if kept or released. The 65 trout ranged in size from about 9 or 10 inches to about 18 inches. Anglers were allowed to keep 6 trout as long as each was 9 or more inches. Fish and Wildlife is to release 450 rainbows during each of the next three weeks. Trout fishing at the lake, which is not traditional trout water of clarity and coolness, should extend to about June. (I also volunteer for Middlesex County Parks and Recreation, so this surveying was a two for the price of one.)

     OSPREY:  I watched an osprey, “Pandion haliaetus,” crash into Jamesburg Lake and grab a fish in its talons. The fish was likely one of the recently stocked rainbow trout. The osprey flew off, circling the lake, carrying the fish. “Unique among North American raptors for its diet of live fish and ability to dive into water to catch them,” according to Cornell University’s “All About Birds” website. The osprey was “seriously endangered by effects of pesticides in mid-20th century; since DDT and related pesticides were banned in 1972, ospreys have made a good comeback in many parts of North America,” according to the “Audubon, Guide to North American Birds.”

Flood prevention and butterflies: The role and potential of stormwater detention basins

This is the second of three articles in a series about stormwater management by Kate Douthat, a third year PhD candidate in the graduate program of Ecology and Evolution at Rutgers. Kate’s research is examining the plant communities that have formed in urban stormwater systems. She is interested in the extensive stormwater infrastructure network in New Jersey and how we can use plants to improve water quality. Kate loves to share her enthusiasm about plants and to teach the public about the stormwater systems in our backyards. She has agreed to develop a series of informative blogs for the LRWP’s readers and will also lead our #booksfortheriver book club starting Fall 2019. You can see more of her writing about plants and water resources on katedouthatecology.com

There are over 16,000 stormwater basins in all of New Jersey (https://hydro.rutgers.edu/). Locally, there are over 1500 detention basins in the Lower Raritan Watershed.  Enhancing the functions of these basins represents a large-scale opportunity to restore environmental quality. Of the 16,000 basins in the state, approximately half are detention basins, meaning that they are designed to drain of stormwater within 72 hours, and remain dry most of the time. Most of these detention basins are lined with grass that is mown weekly or bi-weekly like a lawn. Some basins are lined with dense native plants that are mown only once per year instead of mown grass. Using native plants can save time and money and add badly-needed habitat for pollinators and other insects. When detention basins are lined with native plants, the thicker vegetation can also trap contaminants and prevent them from running into streams and drinking water sources. This type of approach to water management that mimics the natural water cycle is known as “green infrastructure”.

Figure 2 Two types of stormwater detention basins. On the left is the traditional style of basin with grass. On the right is an example of a basin that is lined with dense vegetation to remove pollution.

Replacing mown grass in detention basins with a mix of native vegetation in stormwater catch basins is a practice that is gaining momentum in New Jersey to prevent non-point source pollution from reaching streams and rivers. Non-point source pollution is the pollution picked up by rainwater from the ground that cannot be traced to any particular source. Contaminants of concern for drinking water and stream health include excess nutrients, which can choke waterways, and eroded sediments that are swept up in runoff. According to the USEPA, these non-point source pollutants are the leading cause of water quality problems today (https://www.epa.gov/nps/basic-information-about-nonpoint-source-nps-pollution).

Figure 3 Diagram of a stormwater basin and vegetation. The top figure is an example of a cross-section of a basin, and the bottom figure shows the overall design.

While the concept of using native plants in stormwater basins clearly has merit, we don’t yet which which plants are best suited to this application. There are plant lists out there, and we know which species live in natural wetlands; however, the plants in detention basins must survive difficult conditions including flood, drought, and polluted water. In many cases, the species that were originally planted in detention basins have died out to be replaced by species that come in as seeds from the surrounding area, so the planting lists need refinement. Research is required to determine which plants can succeed in detention basins.

We also don’t know which the best filters are. In general, denser vegetation is better at filtering suspended solids, but it may be that different plants are successful at filtering different pollutants. New Jersey estimates for the removal of suspended solids in vegetated basins range from 60-90 percent based on the design. Estimates of removal rates for nutrients vary, and this process is less well understood. When designing and building basins, it is important to use plants that both survive and provide the best filtering possible. That is why two of the basic questions of my research are: 1) What are the dominant plant species in detention basins? and 2) Which species lead to the best water quality improvement?

By understanding the plants communities that are living in in stormwater basins and how they are related to factors in the environment, my goal is to improve their design and thus improve water quality and the beauty of the landscape. Replacing mown grass with mixed native vegetation can have a cascade of positive effects, including providing islands of refuge for songbirds, pollinators, and wetland plant species in urban landscapes.

Watershed Sculpture Project @ the Mercado!

Article and interview by TaeHo Lee, Rutgers Raritan Scholar

Starting Saturday April 14 and running through October, the LRWP will join Mercado Esperanza in Joyce Kilmer Park (143 Joyce Kilmer Avenue, New Brunswick) for a community market celebrating the food, arts and culture of New Brunswick and its diverse Latino community. Learn more about the Mercado in TaeHo Lee’s interview (below) with Mercado Coordinator Carolina Moratti. In the interview Carolina gives a preview of a new program for 2019 called Mercado Esperanza Kids. As part of Mercado Kids, the LRWP and our coLAB Arts partners invite you and your favorite young person to make “watershed sculptures” for inclusion in our 2019 Sculpture Project gallery installation. The Mercado runs once monthly from 11-4 PM, and will be held on April 14, May 26, June 30, July 28, August 25, September 29, October 27.

Carolina Moratti and her son Abraham met me at a Café on George Street during Rutgers spring break to talk about the monthly Mercado Esperanza on Joyce Kilmer Avenue in New Brunswick. Carolina has worked with the Mercado since it started in 2016, and now serves as Coordinator. Carolina is a Peruvian born American. She moved to the US in 2005, and five years later became a citizen. She was a former student and an instructor of Elijah’s Promise. She currently works as a phlebotomist, partaking in community outreach with women and kids as a hobby. She describes herself as a hard working single mom. Abraham is Carolina’s 12-year old son and a 6th grade student of Von E. Mauger Middle School in Middlesex. Though he was born in the States, he identifies himself as a Peruvian, Central and South American.

T: Tell me about New Brunswick’s Mercado. What is your role at these monthly events?

C:  I started by helping community women, entrepreneurs, and cooks who wanted to build a business. I would coordinate their involvement at the Mercado, helping them sell prepared foods. Later on I started to work managing the Mercado as a whole. I also created the Mercado Esperanza Kids, in which I work with young volunteers to do activities for kids. We have young kids doing temporary tattoos and face painting, and also environmental education. My current priority is emceeing the Mercado, taking care of Mercado Esperanza Kids, and doing social media and public relations.

T: Does the term Mercado mean market?

C: Yes! And Esperanza means hope. Mercados are everywhere in Latin America. Some places are called Marketa but we call ours Mercado Esperanza/Hope. We’re giving hope to people because sometimes they are in a difficult situation. They are homeless, they don’t believe in themselves, they are having a hard time making money, succeeding, and having their voice heard. So we gave them some representation, something that they can be proud of. It is really life-changing.

T: I think it is also very important that this Mercado also allows people to celebrate their culture.

C: People can feel secluded as immigrants in America when nobody sees them. But we give them some representation and help them to be seen. What I love about Mercado is that we keep in traditions. And we’re showing our kids how wonderful it is to go to a local Mercado and experience how we are trying to bring the culture of Mexico here. We’re bringing culture, we’re bringing memories, we’re bringing flavors, we’re bringing music, and all that vibe that we have when we go to another Mercado in any part of South America or Central America or Mexico. We have so many vendors with their kids selling and playing at the Mercado. It’s very good to see that the kids are also getting involved.

T: As part of Mercado Esperanza Kids you are working with the Lower Raritan Watershed Partnership and coLAB Arts to offer a “Watershed Sculpture Project” activity. Why is it important to you to see environmental outreach included as part of Mercado offerings?

C:  The more things we include at Mercado the better. If you go there for food but we are teaching you about how to keep the water clean, how to produce less garbage, how to reuse, how to recycle. If we can give you that information we are making a change because we don’t have that in our culture. A lot of countries in Central or South America don’t do that. People are very excited to see environmental education. It’s a lot of information that is not easy to get to. So if we provide that with Mercado it’s amazing.  Because I know it’s going to make a change.

T: Last summer you participated in a weeklong “Watershed Institute” with coLAB and the Lower Raritan Watershed Partnership. What were some of the things you learned that week?

Abraham: I learned about water quality monitoring, and how it’s important to protect the environment. And I learned that we can protect the environment by making sure we recycle things. We can also clean up after ourselves and after others who have forgotten to do so. We could maybe even make a fundraiser for an environmental cause.

Abraham Moratti conducts visual habitat assessments as part of Summer Institute 2018 “Art and Action in the Watershed.”

T: Do you have anything to say to adults who mainly created the environmental issues that you and I have to inherit for our lifetime and for the following generations?

A: They should have been more careful. They should have been more thoughtful. They should have cleaned up their mess after themselves. They should have been more aware of what they were doing.

Watershed Planning for Environmental Equity

The LRWP is often asked to identify top environmental issues facing our Central New Jersey watershed communities, and every year we develop a “Top 10” list of concerns. Through 2019 we feature one concern a month on our website and explore that issue (and potential solutions) in more detail. In our March essay we bring attention to the state’s failure to act on a mandate to rank contaminated sites. We also consider how New Jersey’s “Home Rule” decision making perpetuates inequitable restoration in our communities. We suggest watershed planning as a more equitable approach to land use decision-making.

Many poor, brown, and black communities throughout New Jersey are saddled with disproportionate legacy contaminant issues in their water and soil. They face greater flood risk and have fewer opportunities for buyouts from flood risks, and have less access to nature, parks, and outdoor space compared to wealthier communities. With respect to legacy contaminants, even when laws are on the books to clean-up our waters, soils, and sediments, time and again the poorest communities are overlooked, with priority given to wealthier watersheds.

In 2009, New Jersey adopted legislation mandating that the state Department of Environmental Protection rank every contaminated site in order of risk and urgency. This “Remedial Priority System” was to serve as a corrective to market-driven remediation that prioritizes clean-up of the most economically desirable contaminated sites. 10 years later however the agency still has not published this list.

NJDEP’s failure to act on this mandate perpetuates environmental injustices and is in violation of the law. We must hold our state agencies accountable for their failure to advance equitable outcomes. We also must consider how land use decision-making at the municipal level perpetuates environmental inequities at a broader scale.

In New Jersey, decisions about how land in a particular municipality is protected, developed, or restored are made by the municipality’s planning board and zoning board. The decision makers that sit on these local boards weigh needs for community and environmental health against the often competing goals of increasing the tax base and expanding or providing new services for municipal residents and visitors. These boards determine how to protect a town (or certain sections of a town) against siting of undesirable uses like power plants, sewage treatment facilities, landfills and incinerators. And they are often charged with making decisions about how to protect against flooding or other natural disasters. There are few tools for planning and zoning boards to use to ensure that their decisions don’t propagate local inequities. Furthermore, because of New Jersey’s “Home Rule” bias in land use decision-making, municipalities are not required to take into consideration the impact on regional growth patterns, existing or planned land uses in adjacent municipalities, or watershed and larger ecological systems impacts.

Examples of undesired regional impacts of local land use decisions include flood control decisions that displace flood waters to neighboring municipalities, and fragmentation of habitat that compromises regional environmental health. Local impacts are felt in low income communities that are not only not prioritized for environmental clean-ups, but continue to be identified for siting of locally undesirable land uses (LULUs). Recognizing this, in January the New Jersey Senate Environment and Energy Committee advanced Senate Bill 1700, which concerns environmental permitting in burdened communities. The “Environmental Justice” Bill is specific to the siting of polluting facilities (power plants, sewage treatment plants, landfills and similar), and would give individuals in our poorest communities the right to petition NJ Department of Environmental Protection for additional environmental and health impacts assessments and a public hearing on permitting processes.

Is this this the best approach we have to righting these wrongs? While any one of us should be able to bring attention to inequities in land use decision making, should the responsibility of designating a community as “burdened” fall on individuals or even on individual communities?

Perhaps other land management approaches, like regional or watershed based planning, can better serve as bulwark against provincial Home Rule interests. These approaches might also balance land uses consistent with human health, environmental, equity, and other goals.

Watershed planning demands integrated thinking and coordination. And watershed management of large ecosystems is inherently science-driven. Climate change has brought attention to the need for science-based land management. Watershed land management is a science-based approach, and watersheds play an increasingly important role in establishing a context for federal, state, and local policy. As such there is increased opportunity for watershed-level planning to guide land use decision-making in the state. Core objectives in watershed management are directly related to water (flood control, water quality and quantity, etc.). Other important objectives include maintenance of biological diversity, wildlife management, urban metabolism, restoration, general environmental preservation, recreation, economic development, and Environmental Equity.

We welcome your thoughts on how watershed-level planning (or other approaches) might be deployed to prioritize action for restoration, advance Environmental Equity, and improve the integration of science with land use decision-making.

South River’s “Brick Beach”

Article and photo by Heather Fenyk

On March 16 the LRWP hosted a clean-up of South River’s Grekoski Park and the adjacent floodplain. Despite the biting wind we had a good turn out, and cleared several dozen bags of trash and plastic from the floodplain, stream, lake bottom, lake’s edge, and wooded areas. While we cleared out hundreds of plastic bottles and dozens of tires, we did not contend with the significant legacy industrial dumping issues at the site, perhaps the most visually striking of which is South River’s “Brick Beach.”

This brick-strewn tidal floodplain is an especially curious aspect of central New Jersey’s industrial legacy. The American Enameled Brick and Tile Company operated at this site from 1893-1934, and many of New York’s brownstones and subways were made from our Lower Raritan clay. My father-in-law’s first job in America was as a brick maker just across the river at the Sayre and Fisher Brick Company.

The American Enameled Brick and Tile Co. was established in 1893 in South River by Julius Steurberg, his son Herbert Steurberg, and Francis Booraem. With offices in New York City, they were major players in New York City’s construction. In June, 1934, the South River plant was destroyed by fire, never to be rebuilt.

The visual experience here is bizarre: hundreds of thousands of 100+ year old bricks “shoring up” the southern embankment of the South River. The walk across this space is likewise disconcerting. It may look like stable ground but, being tidal (photo was taken at low tide) and heavily silted from upstream erosion, the bricks shift significantly beneath your feet.

The South River floodplain is tidal and heavily silted. Photo taken at low tide.

We stumbled across another visually compelling remnant of the the brick industry at this site in the form of an abandoned rail spur. This bit of railway led from from brick manufacture to boats that would travel the short distance along the South River to the Raritan River and across Raritan Bay to New York City.

The water world around us we do not see: Stormwater sewers

This is the first of three articles in a series about stormwater management by Kate Douthat, a third year PhD candidate in the graduate program of Ecology and Evolution at Rutgers. Kate’s research is examining the plant communities that have formed in urban stormwater systems. She is interested in the extensive stormwater infrastructure network in New Jersey and how we can use plants to improve water quality. Kate loves to share her enthusiasm about plants and to teach the public about the stormwater systems in our backyards. She has agreed to develop a series of informative blogs for the LRWP’s readers and will also lead our #booksfortheriver book club starting Fall 2019. You can see more of her writing about plants and water resources on katedouthatecology.com

When it rains, water runs across roads, parking lots, and lawns, picking up pollutants and debris. In order to prevent flooding in developed areas, where the soil is not absorbent because it is covered by pavement or buildings, this runoff, termed “stormwater,” is channeled into storm drains. In nature, wetlands play an important role in the landscape as regulators of flood waters and sinks for excess nutrients and pollutants that are swept up in storm water. Green infrastructure is an approach to water management that mimics natural storage and filtering functions of wetlands by using plants and soils rather than drains and pipes. We don’t yet have a good understanding of which plants are best suited to green infrastructure, so that is the topic of my research.

Once stormwater enters a drain, it can have different fates. One type of municipal sewer system is called a combined sewer system. A combined sewer system combines sewage from your house (toilet sewage) with stormwater runoff from storm drains. This creates a large volume of contaminated water that must be treated at water treatment plants. This type of system is more common in older cities in the U.S., and in 21 cities in New Jersey (https://www.nj.gov/dep/dwq/cso-basics.htm). In New Jersey, most combined sewer systems are in cities near NYC, and a few around Philadelphia. The NJ Department of Environmental Protection hosts a web map to show those locations.

Figure 1 A combined sewer system. On the left, in dry weather, sewage goes to the wastewater treatment plant. On the right, in the rain, stormwater combines with sewage. The volume is too much for the pipes and wastewater treatment plant, and a mix of stormwater and untreated sewage overflows to the river.

The second type of sewer system is a separate system. A separate system keeps sewage containing human waste in one set of pipes, and stormwater runoff from storm drains in another set of pipes. The latter has the the witty nickname MS4 (municipal separate storm sewer system). The sewage goes to a waste water treatment plant, while the stormwater is released to streams or rivers. This relieves pressure on waste water treatment plants and prevents overflows of untreated sewage. However, stormwater is usually contaminated with all of the urban dross it picks up, including pet waste, leaked gas and oil from our cars, excess lawn fertilizers and pesticides. Stormwater moves more quickly over smooth, paved surfaces than rough natural ones, so stormwater can accumulate quickly and cause floods.

Figure 2 An illustration of the different types of sewer systems. On the left: separate storm sewer system. On the right: combined sewer system.

In New Jersey and many places in the U.S., water from storm drains is temporarily stored in artificial detention basins or ponds before draining to streams and rivers. In principle this prevents the water from a rain storm from concentrating in a stream all at once and flooding its banks. A detention basin receives water from the storm sewer, then passively allows it to drain out the other side. The outlet pipe is small though, restricting the water leaving the basin to a low, steady volume. Detention basins were originally designed for flood control, but we are now realizing that they could be redesigned to provide more functions. The expanded functions for detention basins include pollutant filtering, ground water recharge, and provision of habitat.

Most detention basins are lined with grass that is mown weekly or biweekly like a lawn. In order to increase the functions of the basin, managers are changing to a mix of dense vegetation that is mown annually. This simple change can have a big impact and is the subject of my research. In my next post I’ll talk more about why I’m interested in studying detention basins, what I hope to find out, and how it can change our watershed for the better.

Expect the Unexpected

Article and photos by “Voices of the Watershed” Contributor Joe Mish

A white fronted goose, rarely seen west of the Mississippi river, enjoys grazing on central New Jersey grass.

Long before President Eisenhower signed the interstate highway bill into law in 1956, The Atlantic, Central and Pacific flyways served as major superhighways for migrating birds.

The primary exit ramps for these super flyways are the rivers which radiate out along the north-south migration routes to distribute the migrating birds far and wide.

New Jersey sits directly on the Atlantic flyway, bounded by the Delaware River and the Atlantic Ocean. Within the state’s interior flows the Raritan River, the longest inland river in the state which serves as a major migratory off ramp.

The confluence of the North and South Branches may then be considered the prime visitors center and rest area, as birds funnel down the Raritan to disperse inland.

Look at a colored distribution map in any bird book and discover that many species are specific to defined regions.

You might not expect to see a rufous hummingbird from the northern Pacific coast, sipping nectar in central New Jersey. However, in 2012, a rufous hummer showed up in our midst and stayed the winter, surviving by the kindness of human intervention. Marlene Scocco reached out to this wayward hummer providing food and shelter, causing a stir in the birding community which gratefully documented this migratory anomaly.

Checking the records for rare hummingbird visitors to New Jersey, other hummer species like the calliope and green violet eared were also documented.

How these birds end up on the east coast is pure speculation. The point is they do and they are here for you to discover.

Feathered visitors from faraway places to the Raritan valley are not just limited to hummingbirds. In 1963 I was handed a small owl taken from a guard tower in the Raritan arsenal. It died shortly after. I mentioned this to a friend’s dad who was an avid bird watcher. Told him it was a boreal owl. He smiled and assured me it was probably a saw whet owl. We ended up at the Newark Museum and showed it to the curator, Irving H. Black. Confusion ensued and experts from across the country were consulted. The experts concluded the bird was indeed a boreal owl. It set a new record for the southernmost sighting in the US. The boreal owl, briefly known as the Richardson owl, is a fulltime resident of the coniferous forests of the arctic region. The owl is preserved as a study skin at the Newark museum.

The visitors keep coming. In mid March of this year I noticed an inconsistency in the color pattern of a flock of grazing geese, as I drove by. The geese blended together in one giant mosaic, painted with repetitive splashes of black, white and brown. I pulled over and focused on the colors that didn’t belong.

I was looking at a white fronted goose, another bird that was obviously unfamiliar with distribution maps found in bird books.

The white fronted goose is rarely seen east of the Mississippi river, the main artery of the central flyway. To see a white fronted goose in central NJ is therefore an unexpected surprise and evidence that nature has a tendency to violate scientific generalizations.

The following week, a Canada goose with an orange and white collar marked OHOX was observed along rt 22. It also had a metal band on its left leg. While editing images, I was shocked to see the goose standing next to it also wore a leg band. Reporting this goose to the USGS bird banding website I was provided with a certificate noting that the goose was a female, banded as a flightless gosling near Varennes, Quebec, Canada on the Fourth of July, 2016.

Adding to the distinguished list of local visitors was the osprey I observed April 7, 2016, just upstream of the confluence of the North and South branch. The osprey had a blue plastic band on its left leg, with stacked letters, DV, visible on one of the images taken. Again, making a report to the USGS banding website, a certificate soon arrived, stating the osprey was born on a bulkhead in Portland, Maine and banded on July 27, 2011. To report a banded bird, visit the USGS bird banding website, bandreports@usgs.gov

The spring migration is now in full swing. And along with colorful warblers, ruby throated hummingbirds, woodcock and osprey, come the errant travelers.

Diverging from their evolutionary migration patterns, these intrepid winged visitors explode the myth that, “birds of a feather stick together”.

Migrating birds that nest in our region, along with birds just passing through, are now appearing along our waterways. The confluence that forms the Raritan River is the staging area that hosts a feathered extravaganza of unimaginable variety.

Mill Brook: Portrait of An Urban Stream

by LRWP Streamkeeper Susan Edmunds

Thirty years ago, my husband and I moved into a house down at the end of a quiet street in Highland Park. Beside the house, in a low area, ran a little stream, nameless as far as I knew. I imagined making a garden beside it until I saw the muddy water that rushed through after heavy rains, rooting out vegetation, clawing away at the stream banks, and depositing all manner of storm debris. I came to think of the stream as nothing but a source of problems. Years went by. I sought advice from various experts and made some progress in resolving some problems, though others remained.

Eventually, in the Rutgers Environmental Stewardship program, I learned that the problems of urban streams are predictable and can, at least in theory, be mitigated. I learned that, with active community involvement, even large rivers have been significantly restored. The RES program led me to the Lower Raritan Watershed Partnership and a plan to document the stream that I now knew was called Mill Brook.

I took pictures and made lists of storm sewer outfalls, eroded portions of  stream banks, retaining walls in various states of disrepair, and multiple types of litter, wondering how this information about predictable problems might be useful. Increasingly, my attention was caught by the magnificently tall trees in the Mill Brook stream corridor, the bird song high above me, the calming gurgle of the water at my feet, and the sense of being far away while actually only a few yards from the hubbub of one of the most densely populated regions in the United States. I have learned that Mill Brook has been a source of much happiness for others, too, over the years.

I composed this Story Map Mill Brook: Portrait of an Urban Stream to invite you, the reader, to experience for yourself this valuable natural resource that runs like a ribbon through our community. I hope that a virtuous circle may arise in which the value of Mill Brook is acknowledged in our communities so that we willingly do what it takes to resolve problems created by developments that include our own homes. In return, Mill Brook will increase in value to us because it is a healthier natural resource and because we will have the satisfaction of caring for it.

(Making) Room for the River: Applying Dutch River Management to the Raritan

Article and images (except as noted) by Sanja Martic, Rutgers Department of Landscape Architecture Graduate Student.

“Man wants to take the river’s natural storage reservoir and make no compensation for it. The river contends it is against Natural Law and cannot be done. The river is right.”

The Dutch Room for the River Program (RfR) was conceived in 2007 as an integrated river basin management strategy for the low-lying flood prone and densely populated areas of the Netherlands. As part of this Program, water management is conducted via a specialized regional “Water Board,” working in partnership with the Dutch National Ministry and the Ministries for Transport, Public Works and Water Management. Through RfR the Dutch Water Board takes a four-pronged approach to water management. The four key characteristics of the RfR approach include: 1) large scale river region landscape architectural design thinking; 2) a focus on collaboration, with landscape architecture playing a facilitating role; 3) considering the landscape as a system of layers; and 4) anticipating that natural processes will change and enhance the design over time.

As in the Netherlands, significant portions of New Jersey’s Lower Raritan River are in low-lying densely populated areas. Flood protection is of paramount importance and a matter of human safety and economic security. However, the Home Rule focus of New Jersey’s local governance limits the potential for thinking in a landscape context, no comparable “Water Board” serves as coordinating entity for water management, flood control prioritizes human land use layers, and engineering controls trump considerations of natural hydrological processes and flows. There is much to learn from the Dutch RfR example. In what follows we provide background information on RfR, and consider the Dutch Water Management approach in the context of New Jersey’s Raritan River and Lower Raritan Watershed.

Historic Approach to River Basin Management

In riverine areas around the world, the industrial revolution demanded capitalization of the river’s territory and its water. As a result, many river basins were heavily engineered: rivers streamlined, river basins minimized, and creeks and small streams culverted or replaced by canals[1]. These practices, in combination with development over time, resulted in floodplains that restricted the river and required repeated heightening of flood defenses[2]. There was no appreciation for the river ecosystems, and water was seen as a threat and as something that needed to be controlled. Over time, conflicts arose regarding use of the floodplain and the its water. And the Industrial Revolution and subsequent development left behind a lasting pollution legacy: abandoned infrastructure and degraded water and soil quality. Meanwhile, the expanding population’s need for potable water and space for a safe habitation increased, causing a decline in the river basin surface. In recent years, rising intensity and quantity of extreme precipitation events associated with a changing climate, coupled with increase of the impervious surface cover, further complicate water management issues.

Room for the River (RfR) Emergence and Approach

In the Netherlands, traditional water management methods were challenged following destructive floods in 1995, caused by record extreme precipitation events. It was clear that new flood levels required a different approach towards river management. Different approaches to water management call for different methods: many rely heavily on engineering while others emphasize a more natural approach. Room for the River Program (RfR) finds a middle ground. Instead of gradually reducing the area that rivers occupy, this approach allows the river to expand over a larger territory[3]. RfR brings together the worlds of water management and spatial planning, engineering and ecology. Tools are varied and include dredging at one extreme, and measuring spatial quality on the other, and they are put into service of two main objectives: improving safety by reducing flooding of riverine areas, and “contributing to the improvement of spatial quality of the riverine area”[4]. Although hard to quantify, this second goal is particularly interesting from the landscape architecture perspective as it considers quality of the space.

Spatial quality within the RfR approach is defined as “a property of the resulting landscape after a plan has been implemented.”[5] A good design is further judged by three criteria: hydraulic effectiveness, ecological robustness and cultural meaning and aesthetics. Cultural meaning and aesthetics criteria call for enhancing the scenic beauty, tailored to a range of sites that could be classified as natural, urban or countryside. Ecological robustness endorses designs that are long lasting, self-sustained, build upon natural processes, and are low maintenance. This is achieved through combining natural hydrology with morphological and biotic processes to achieve stability in riverbed and floodplain.[6] This means that plans have to be functional in the case of floods, but at other times must accommodate livability, wildlife habitats and areas usable as a public good. Design is informal and natural while providing maximum access for recreation, with spaces intended to reveal the spirit of each individual site of intervention.

Room for the River (RfR) Implementation and Practical Measures

In the Dutch model, spatial quality assessment requires development of a special Q-team (quality team) composed of members from different but complimentary disciplinary backgrounds. The Q-team’s role is to produce an independent recommendation on enhancing spatial quality through coaching designers and planners, peer review of the designs and plans, and regular communication to the Ministries of Transportation, Public Works and Water Management[7]. This calls for significant transdisciplinary cooperation between planning and design, with an equal role for the landscape architect, urban planner, river engineer, ecologist and physical geographer. Practical measures (Figure 1) are applicable at large scale and fall into three categories ranked by complexity of integration of flood risk measures with spatial measures. These categories include technical measures (deepening the river bed, lowering groynes, strengthening dikes), measures within the banks (lowering the floodplains, removing obstacles), and measures beyond the banks (high-water channel building, dike relocation, water storage). In addition to evaluating project’s outcome, the team also evaluates the quality of the integrative collaborative design process.

Precedent for RfR in the United States

The RfR approach is not entirely new to the United States. An early similar effort was forwarded in New Orleans in 1927, following devastating flooding events in the Mississippi River delta. Like the Dutch who relied on dikes for flood protection, the Mississippi delta community relied on constant raising and enforcing levees, increasingly restricting the surface size of the natural flood plain. The 1927 flood prompted a reevaluation of the Mississippi River management approach. Official Congressional hearings were held and involved the U.S. Army Corps of Engineers, the Mississippi River Commission and expert witnesses such as Gifford Pinchot[8]. Discussion revolved around engineered control of the river proposed by the Army Corps of Engineers, and an approach in which nature would be allowed more leeway[9] supported by Pinchot, James Kemper and others. The latter view resembles the RfR approach as it calls for allowing more room for the river through widening the flood plain.

RfR Methodology

1. Large-Scale Design (Entire river region)

The large scale landscape architectural design approach considers “not only detailing of small-scale elements, but also at the scale of the river system as a whole”. [10]

2. Collaboration

The landscape architect plays a central role of coordinator between planners, architects and other partners. Fliervoet and Den Born studied and evaluated the RfR’s collaborative process from a stakeholders’ perspective. They concluded that the success of the approach is highly dependent on the cooperation and collaboration of multiple entities occupying the watershed with emphasis on the local knowledge. The biggest obstacles to collaboration stated by the participants, were the lack of an overarching, integrated maintenance vision and a lack of coordination between the authorities.[11]

3. Considering the Landscape as a system of layers

o        Basis of Landscape (soil, water, ecosystems)

o        Network Layer (roads, waterways energy infrastructure)

o        Occupation and Land Use (living, working, recreation)

o        Time Layer (all layers develop within their own time scale)

4. Creating Conditions: Responding to natural processes

Natural processes are expected to change and enhance design over time.

Applying the RfR Methodology to the Raritan

Large-scale Design of the Raritan River Floodplain and Regional Network

The first characteristic, the large scale of design as applied to the Lower Raritan, requires creating a comprehensive masterplan with projects spanning the entire Raritan watershed. RfR site plans would become small parts of a large Raritan Watershed Masterplan. The masterplan would be guided by a comprehensive vision of integrated water management, with a regional greenway connection as an integral part. Directly connecting the City of New Brunswick to the greenway network would be a key component of the masterplan, as New Brunswick is the largest settlement on the banks of the Raritan River. Collaboration between many governing bodies is essential. At the federal level the governing bodies to involve include USACE, USCG and the Advisory Council on Historic Preservation. At a state level governing bodies to involve include NJDOT, NJDEP and Land Use Regulations and Ecological Services Field Office. Regionally the Delaware and Raritan Canal Commission and counties such as Middlesex, Somerset, Hunterdon and others should be involved. At the local level the municipalities along the Raritan River banks including New Brunswick, Piscataway, Franklin Township etc. would require representation.

Large scale design requires examination of large-scale network connections. Analysis in the Raritan River context reveals several greenway network opportunities (Figure 2). Metropolitan areas of New York City and Washington D.C. are roughly framed by the Appalachian Trail to the North and the proposed alignment of the East Coast Greenway to the South. They are further enclosed by the major East Coast rivers that bisect the Trail and the Greenway on their way to the Atlantic Ocean. The Hudson River Valley to the East, the Delaware and Lehigh National Heritage Corridor, and the Chesapeake and Ohio Canal to the west all form a regional trail system matrix. This blue and green matrix provides unique opportunities for cross connections of the corridors and interactions with nature and culture to one of the world’s densest contiguous urban populations.

The East Coast Greenway is an aspiring walking and biking route stretching the length of the US East Coast with southern terminus in Key West, Florida and northern Maine. Once actualized, the East Coast Greenway will be 3000 miles long and epitomize the bond between communities and nature by connecting the exist green open space along its route into a unique linear corridor. Initiated in 1991, with forming of the East Coast Greenway Alliance, the vision of Greenway designers, “represents a commitment to public health, environmental sustainability, economic development, and civic engagement”[12].

The existing Appalachian National Scenic Trail, which partially passes along New Jersey’s northern border, is currently the longest hiking footpath in the world at 2190 miles long[13]. It was first proposed by a regional planner Benton MacKaye in a 1921 document titled “An Appalachian Trail: A Project in Regional Planning”.  MacKaye’s vision initiated the idea of land preservation for the purposes of recreation and conservation. The idea started to materialize in 1925 and was actualized in 2014 when the last stretch of the Trail was formally acquired and protected.  Today, the trail is visited by over 3 million visitors a year as it bisects fourteen US States from Georgia to Maine.[14]

The East Coast Greenway’s proposed alignment crosses the narrow waist of New Jersey using the D&R Canal Park as a major junction. Canal Park’s Masterplan recognizes the most important quality possessed by this linear park to be the role it can perform as a connector. Canal Park no longer links New York City and Philadelphia, but it does join central New Jersey communities, different land forms and different kinds of natural areas, and connects New Jersey with its heritage[15]. Extending the Canal’s connection back into the city of New Brunswick would align with the Canal Commission’s Masterplan and benefit New Brunswick’s future development.

The Delaware and Lehigh National Heritage Corridor runs along the Delaware River on the Pennsylvania side, parallel to the D&R Canal Park. It is an indirect connection between the proposed East Coast Greenway, through the D&R Canal Park to the Appalachian Trail. It is also an example of a linear park run by a nonprofit organization, while Chesapeake and Ohio Canal is a linear park that is part of the National Park system. The Chesapeake and Ohio Canal is another significant connector between the Appalachian Trail and the East Coast Greenway close to a major metropolitan area.

When the Delaware and Raritan Canal was built in the 1930s it permanently linked the Delaware and Raritan watersheds, creating opportunities for connection. Since that time, construction of Route 18 through New Brunswick, which established a several mile stretch of roadway immediately adjacent to the Raritan, severed this historic network connection, in particular in the area between Buccleuch Park and the Landing Lane Bridge. Today, the City of New Brunswick’s unique geographic position could once again benefit future development should access impediments to the D&R Canal Park be removed, resulting in expanded access to not only Canal Park but regional networks like the East Coast Greenway. There would be many mutual gains: the local community would have better access to nature and everyday recreation and day-hiking without having to drive to the trail. New Brunswick’s rich local history would add to the richness of the trail’s experience. The local economy would benefit from hiking and biking traffic generated by the Greenway. Finally, being a part of the future East Coast Greenway’s shared vision could be an invigorating driver of the nature stewardship and future community and economic development.

Collaboration of Local, Regional, National and State Partners

Collaboration and coordination, conducted by a landscape architect, may include working with a variety of professional partners on a local level. In addition to planners and architects, other professions to engage include social scientists, geographers, ecologists, river engineers, biologists, historians, archeologists and civil engineers.

Considering the Raritan River Floodplain and Watershed Landscape as a system of layers

The RfR “system of layers” approach consists of a base layer, network layer, potential for use layer and time layer (Figure 3). Layers provide a basis for site evaluation within the Lower Raritan. Expanding the original RfR methodology, we have conceived of each of the four categories of layers as worth 25 points for a total of a 100-point evaluation system. The lower the score for specific site, the better the opportunity for enhancing it.

Figure 3: Adopted Diagram of Layers of Landscape

For example, considering New Brunswick in relation to the regional greenway network, the four areas identified as having the best opportunity for creating connections between the New Brunswick and regional greenways are the Key Connector Streets (Urban Core Green and Blue Corridors), Waterfront Access Points, Raritan Bike Path, and the “D&R Canal Link” (Figure 4). These] specific sites should then be evaluated for their soil, water and air quality within the base layer, and for the existing roads, railroads, bridges/tunnels, walking and biking paths and green networks within the network layer. The Network Layer evaluates the existing networks presence and connectivity. Points (0-5) are given for the presence of the networks within the site and more points for their current connectivity. All the sites have a presence of at least one network, however in some cases those networks are enhancing and in others reducing walking and biking connectivity. Increasing connectivity becomes a goal for this layer.

Figure 4: Simplified Connections Diagram

The Base Layer evaluates the soil, water, air, plant and animal life conditions of the landscape. 0-5 points for soil quality are allocated depending on its permeability as well as its ability to support life. In the urban environment soil is often covered by pervious surface or is heavily compacted resulting in a low rating. Water movement is evaluated based on the speed of its movement within the site. Faster movement (poor infiltration) is rated lower. Water quality is associated with the ability of site to treat the stormwater runoff. Water that leaves the site cleaner results in higher points. Air quality depends on the site’s micro location. Sites near major roads with little vegetation are rated lower. Finally, existence of plant and animal life is rated depending on a level of presence. Based on the rating, design goals that emerge are: increasing surface permeability, slowing down runoff by retaining water in the landscape for longer periods, decreasing soil compaction, and creating conditions that support more plant and animal life.

Our addition to the methodology also includes expansion of the “potential for use layer” by which each of these sites are evaluated for their potential to support any of 25 different activities that could take place within the area once it is redesigned. The Potential for Use Layer allocates one point for each activity that can currently take place within an area. The goal for this layer becomes increasing the number of future potential use of the space.

Finally, the time layer evaluates presence of historic and cultural artifacts on one end and a potential for future ecosystem health improvement on the other. Sites that contain historic and cultural artifacts are rated higher, as well as the sites that will be able to, over time, enhance the ecosystem health. Ecosystem health is prioritized over the existence of historic and cultural artifact. For example, a city street has less potential for the improvement of the future ecosystem health than the river bank.


Figure 5:  Proposed Connections Diagram

The redesign of the existing key connector streets within the City of New Brunswick enhances the biking and walking experience, while leading to the waterfront access points. Commercial and Joyce Kilmer Avenues are green corridors, chosen for their proximity to the local schools, green open space, highest population density and wide traffic lanes. These two thoroughfares have a great potential for “road diet” interventions, such as narrowing traffic lanes and adding bumpouts at street crossings in order to calm traffic and thus enhance safety of pedestrian and bicyclists. They would further create opportunities for bringing nature closer to the local communities by becoming way finders for the Raritan River as well as the green corridors with more pervious surface and vegetation (Figure 5).

Route 27 or French Street and Hamilton Street are already main routes of access that are further enhanced by adding new and improving existing bike lanes, and improving pedestrian experience by adding bump outs and lowering curbs. Similar interventions could be applied outside of the immediate study area. Franklin Township’s Franklin Boulevard is the next such opportunity. The existing Mile Run stream corridor, in conjunction with the key connector streets, forms a matrix of river connections. The Mile Run stream corridor is now accessible through this matrix, offering further opportunities for engagement with water and nature.

Access to the waterfront is strengthened using various traffic calming techniques such as raised, textured crossings, lowered speed limit and narrowed traffic lanes. These approaches ensure safety and an enhanced pedestrian experience. Redesigning the Raritan bike path by adding access points, widening its surface, and adding small, localized interventions helps create a sense of place and wayfinding. Materials and forms chosen for intervention help to further connect community to the unique industrial and postindustrial history and ecology of the place. Finally, the “Canal Link” links fragmented biking and walking paths ending within the area of the River Road, Landing Lane, Buccleuch Park and Spillway, through an elevated walkway bridging the impediments. This walkway becomes the final interlocking link restoring connection to the D&R Canal Park, East Coast Greenway and the Raritan.

A final key characteristic of the RfR program requires considering how including natural change over time can be integrated in the designed system, so that it could start functioning as a natural system. Within the landscape architecture field, time is always an important element considered in designing a landscape. The question: “How will a landscape change throughout the years?” is a core design consideration. However, change is usually considered as it relates to human use and needs. In the RfR case the emphasis is on the health of the entire ecosystem, and the ability of landscape to be “managed” by natural processes, thus making it self-sustained and supportive for all living beings. Choices of materials and forms should be made considering this final concern.[
