DREDGED MATERIALS & CLIMATE CHANGE PILOT

INTRODUCTION

The Port Authority of New York & New Jersey (PANYNJ) is exploring the beneficial use of dredged materi-als in ways that are not only environmentally sustainable but also proactive about climate change throughthis Dredged Materials & Climate Change Pilot Project. Both active and inactive port areas are facingincreased risks from climate change. These low-lying waterfront areas are vulnerable not only to rising sealevels, but also to more frequent, severe storms, and increasing water/air temperatures. Given their proxim-ity to shipping channels, port areas are also logical places to target for the handling and use of dredgedmaterials. This pilot is intended to play a significant role in protecting port areas by bringing together vision-ary thinking and creative responses to climate change with regional knowledge about dredging and dispos-al of dredged materials. The PANYNJ sees this as an opportunity to apply the resulting innovations in waysthat will make a realistic and feasible contribution to our evolving understanding of how to address thethreats from climate change on all our waterfronts.

Objectives

The objective of this project is to apply existing dredgeexpertise to new challenges in port areas and propose afuture demonstration project based on both creativeideas and engineering realities. During the first phase,this pilot was aimed at 1) analyzing state-of-the-art tech-nologies for the use of dredged materials, 2) evaluatinga range of possible applications that could help addressclimate change, and 3) proposing a future demonstra-tion project. Following Phase 1, the PANYNJ will struc-ture a second phase of work for implementation.

Sponsors, Funding & Advisory Group

The pilot is sponsored by the PANYNJ and fundedthrough the Bi-State Dredging Funds. In addition, thereis a Project Advisory Group of federal, New York Stateand New York City public agencies and local communityboards.

The challenges of climate changelead us to reexamine traditional

approaches to coastal managementand to seek new, creative solu-

tions to supplement the range ofavailable adaptation strategies...

Studies that provide information on the benefits and drawbacks of emerging strategies will be helpful as part of this effort.

Pilot projects that gather empiricaldata on the effectiveness and ecological value of alternative

strategies will also be valuable.

I N T R O D U C T I O N Southwest (SW) Brooklyn Waterfront Study

Port cities around the world are facing the questionof how to combine economic development with envi-ronmental sustainability, especially in light of urgentglobal economic and environmental challenges.Under the PANYNJ's leadership, this dynamic studyof the SW Brooklyn waterfront was started in 2009based on international best practices and hasexplored many facets of the challenge, from modern-ization of industry to realignment of the workforceand mitigation of climate change. The DredgedMaterials & Climate Change Pilot Project is one of anumber of pilot projects that have been undertakento support sustainable redevelopment of SWBrooklyn's industrial port areas.

Project Team

The PANYNJ's Department of Planning and RegionalDevelopment is overseeing an inter-departmentalteam for this pilot as well as a multi-disciplinary teamof consultants for Phase 1. The other PANYNJdepartments involved are: Engineering/ArchitectureDesign Division, Government and CommunityRelations, Office of Environmental and EnergyPrograms, and Port Commerce. The project consult-ing team is led by Nautilus InternationalDevelopment Consulting, Inc., which is the primeconsultant to the PANYNJ on the SW BrooklynWaterfront Study as a whole. Nautilus International'ssubconsultant on Phase 1 was Langan Engineering,Environmental, Survey and Landscape Architecture,DPC, who acted as project manager of the technicalteam and subcontracted with ARCADIS US, Inc. andGuy Nordenson and Associates for the technicalaspects of the project.

SW Brooklyn includes the communities of Red Hook,Gowanus and Sunset Park with Governors Islandnearby. It has a strategic position at the mouth of theNew York Harbor.

DREDGED MATERIALS & CLIMATE CHANGE PILOT

BENEFICIAL USE OF DREDGED MATERIALS (B.U.D.s) FOR CLIMATE CHANGE APPLICATIONS

There are a wide variety of possible coastal protection strategies for which the beneficial use of dredgedmaterials could play a significant role. These include off-shore and on-shore strategies as well as applica-tions in the inter-tidal zone and at the shoreline itself.

The following list categorizes beneficial use of dredged materials for climate change applications by theirlocation relative to the shoreline. The terminology used corresponds to New York City's Coastal ClimateResilience: Urban Waterfront Adaptive Strategies, which contains an inventory of urban strategies and adetailed analysis of how to identify and evaluate potential applications for individual buildings and waterfrontcommunities. That report builds on Vision 2020: New York City Comprehensive Waterfront Plan andexpands its goal of increasing the City's climate resilience.

On working waterfronts, where access and navigation by vessels is critical, certain applications for dredgedmaterials are not viable, such as underwater berms and bulkhead softening. However, many possibilities arefeasible in these maritime areas and these are indicated below with asterisks(*).

DREDGED MATERIALS & CLIMATE CHANGE P I L O T

Dredging to maintain the depths of navigation andapproach channels has been taking place in NewYork's harbor since the early 19th century. While theharbor's estuary provides excellent sheltering forvessels, its natural depth is only about 18 feet.Dredging removes sediments that have settledunderwater through natural erosion or urban runoff.Since 2005, the harbor has been undergoing aHarbor Deepening Project (HDP) to provide suitablenavigation channels for new Post-Panamax contain-er ships designed for the widening of the PanamaCanal, which will require depths of 50 feet. Initialfederal authorization was received in 1986 to deep-en channels to 45 feet and a second authorizationin 2001 allows deepening them to 50 feet.

When the current deepening work is completedwithin the next year, maintenance dredging requiredto ensure operation of the harbor's shipping chan-nels will increase to approximately two million cubicyards/year. During the HDP, those sediments weredredged as "overburden" in the course of the deep-ening work. While pollution reduction and cleanup

efforts have improved the quality of sediments overmany years, the near-term quality of that mainte-nance dredged material will be approximately 45-50% fine-grained sediment rich in organic material,or "black mud," that is not suitable for ocean place-ment.

Current uses of dredged materials, aside fromocean placement, include beneficial projects likeupland site remediation, beach replenishment, andhabitat restoration. New placements options need tobe explored and new models for management ofdredged materials are being developed that encom-pass not only the economic viability of the harbor,but also its environmental protection and the qualityof life for waterfront communities.

The Port Authority of New York & New Jersey(PANYNJ), while not the largest dredger in the har-bor, is a significant one and currently 100% of itsdredged materials are used beneficially, transportedprimarily by barge rather than truck. The PANYNJhas been an innovator in the beneficial use ofdredged materials for habitat restoration (seePANYNJ's Restoration of Eroded Salt MarshIslands, p.8). One of the main goals of the DredgedMaterials & Climate Change Pilot Project is to con-tribute to the regional dialogue about finding newplacement alternatives and state-of-the-art dredgetechnologies.

DREDGE TECHNOLOGIES & RECOMMENDATIONS

During this pilot project, a search was performed of industry literature and governmental organizations toidentify and inventory relevant current technologies for the beneficial use of clean dredged materials for cli-mate change applications in the United States, the Netherlands, and elsewhere. These fell within the over-all categories of geotextile-based technologies and non-geotextile-based technologies. Geotextiles aresemi-porous fabrics that allow water to seep out while retaining the solid dredge particles.

Relevant technologies were then analyzed to compare safety, environmental impacts, costs and benefits,and constructability. An assessment was also made of the associated regulatory requirements. The threerecommendations on the following page were made by the technical team:

Geotextile-Based Technologies

Geotextile bagsGeotextile mattresses

Geotextile tubes

Non-Geotextile-Based Technologies

Hybrid Gabions for Off-Shore Breakwaters

An innovative approach for constructing an off-shorebreakwater was recommended where there would be ahybrid construction in which stainless steel gabion bas-kets, traditionally filled with stone, are lined with geotex-tile fabric or bags to contain dredged materials. "Greengabions" might also be added to encourage the growthof habitat. Key advantages to testing this ground-break-ing technology would be its cost effectiveness and mod-ular configuration. The ability to stack the gabions couldprovide flexibility for future adjustments to sea level rise.

Constructed Wetlands for the Inter-Tidal Zone

A combination of geotextile bags or tubes with freeplacement of dredged material was recommended forthe inter-tidal zone. The geotextiles were proposed tocreate a "toe" anchoring the freely placed dredgedmaterials and reducing its erosion. The combinationcould be contoured to accommodate a variety of sub-merged, inter-tidal and shoreline vegetation. Key advan-tages to testing this type of wetland would be that it canbe modified to accommodate site-specific conditions fora range of waterfront areas.

Geotextile Berms On-Shore

Geotextile tubes were recommended for their flexibilityto accommodate natural curvilinear land forms on-shore. It was proposed they be capped with shallow soilthat could be landscaped and constructed in a way thatwould support a pedestrian path or bikeway. Key advan-tages would be that geotextile tubes are relatively inertfor on-shore applications and, consequently, have mini-mal maintenance requirements.

PANYNJ RESTORATION OF ERODED SALT MARSH ISLANDS

Jamaica Bay, located in Gateway National Recreation Area, is the largest tidal wetland complex in the New YorkCity metropolitan area, valuable to wildlife and fisheries habitat as well as the human environment. Historically,the Bay was known for an abundance and diversity of shellfish. In addition, with extensive marsh islands, tidalcreeks, mud flats, and brackish water, the Bay served as an important nursery and feeding ground for manyspecies of birds and fish. Mapping analysis has shown that nearly half the Bay's vegetated marsh habitat disap-peared between 1924 and 1999, with an estimated 220 acres of salt marsh loss in the five years between 1994and 1999. At this increasingly rapid rate of erosion, the New York State Department of EnvironmentalConservation (NYSDEC) estimated that the salt marsh habitat could vanish by 2024 if no action was taken by thenatural resource community.

In response, focus was placed on opportunities for beneficial use of dredged materials in Jamaica Bay. In 2006,as part of its mitigation effort to offset environmental impacts from the Harbor Deepening Project (HDP), the PortAuthority of New York & New Jersey (PANYNJ), along with its federal partner the US Army Corps of Engineers(Army Corps), placed an estimated 250,000 cubic yards of dredged material from the Ambrose Channel to restore39 acres of Elders Point East Salt Marsh Island to its original 1979 footprint. Dredged sand was placed withinthe historic 1970s footprint to an elevation suitable for low marsh growth to be submerged at high tide, and thenvegetation was planted by hand. In 2009, the New York Project Delivery Team received the Coastal America SpiritAward for their outstanding efforts to preserve the marsh.

In 2010, the PANYNJ and Army Corps partnered with New York City Department of Environmental Protection,NYSDEC, and National Park Service to restore an additional 40 acres at Elders Point West using dredged mate-rials from the HDP. Following the success of those efforts, the partners continued working together to restorethree additional salt marsh islands: Yellow Bar Hassock Marsh Island, Black Wall and Rulers Bar's. Together,these restored over 150 acres of marsh and wetlands in Jamaica Bay.

All the island restorations are being closely monitored by the PANYNJ and Army Corps’ team. Erosion is beingdocumented with a series of aerial photos that are flown every couple of years. Over the last five years, monitor-ing has shown an 80% survival rate of the planted habitat, including its flora, fauna and aquatic life. The provenbenefits include restoration of this coastal habitat as a productive tidal salt ecosystem for a variety of fish, birdand wildlife species, and protection of the Bay's shorelines.

PROPOSED DEMONSTRATION PROJECT

SW Brooklyn's waterfront is vulnerable to risks from climate changes that are prevalent throughout theregion, such as storm surge and sea level rise. Therefore, a demonstration project in this area can providean opportunity to make a larger contribution to the region's long-term environmental safety.

The first step in developing a demonstration project was to investigate the need for climate change protec-tion along SW Brooklyn's waterfront and assess the effectiveness of the recommended technologies at pos-sible SW Brooklyn locations. Then, a site-specific future demonstration project was proposed using theselected technologies to test out their potential to provide direct benefits at reasonable costs.

Climate Change Vulnerabilities in SW Brooklyn

This project benefited from the City of New York's post-Hurricane Sandy report PlaNYC: A Stronger, MoreResilient New York, which looked in depth at theBrooklyn-Queens waterfront and documented bothwhat happened during the storm and what could hap-pen in the future. Under major risks for the Brooklyn-Queens waterfront, the report states: "Given theWaterfront's coastal exposure, the most significant cli-mate change-related risks for its neighborhoods arestorm surge and flooding from coastal storms, which islikely to be exacerbated by projected sea level rise."1

The low elevation and geographic location of the SWBrooklyn waterfront makes it particularly susceptible toflooding during storm events. During Hurricane Sandy,the low-lying shoreline allowed storm surge to pene-trate far inland and reach depths over six feet. Thenew FEMA flood maps issued after Sandy in June2013 indicate both expanded 100- and 500-year flood-plains and increased zones where waves can reachover three feet in height (VE zones).

In addition, the SW Brooklyn waterfront is vulnerableto sea level rise, which has been projected by the 2013New York City Panel on Climate Change to reach up to11 inches by 2020 and 31 inches by 2050 at the highend. While there is uncertainty surrounding how muchsea levels will actually rise, recent research has con-firmed that storm surge and waves will be amplified bythat rise and lead to increased extent of inundation,deeper surge, and higher waves.

Demonstration Project Site

The site selected for the future demonstration pro-ject is located on Red Hook's waterfront betweenPier 41, the Liberty Warehouse, and Pier 44, homeof the Waterfront Barge Museum (roughly betweenVan Dyck and Conover Streets). This property hasan active working waterfront and is owned by TheO'Connell Organization, who has restored historicmaritime structures, built waterfront walkways andopen spaces accessible to the public, and supportedthe economic revitalization of Red Hook for manyyears.

Among the reasons for selection of this site werethat Red Hook suffered extensive damage duringHurricane Sandy and that its geomorphology andsoils - a hardened, sheltered bay plain2 with landfill -is similar to many other vulnerable waterfrontsaround the region.

DREDGED MATERIALS & CLIMATE CHANGE PILOT1) Off-shore breakwaters using gabions lined withgeotextiles were proposed to a height of +2' NorthAmerican Vertical Datum of 1988 (NAVD88) wheresurface water would rise to the top of the breakwaterat high tide and the upper four feet would beexposed at low tide. These breakwaters would beconstructed and monitored as the first of the fourelements in order to protect the others. The antici-pated benefit of the breakwaters is to provide waveattenuation.

Issues that would need to be addressed before afuture demonstration project with breakwaters couldmove forward include: - value and effectiveness of hybrid gabion breakwa-ters to reduce flooding and decrease wave action,

- the costs of mitigation for loss of in-water habitatand filling of open water,- coordination with the breakwaters proposed forthe Bay Ridge Flats in NYC's PlaNYC: A Stronger,More Resilient New York,- navigational issues such as openings in thebreakwater, - life span of the gabions, geotextiles, and fasteningsystems, - scalability for sea level rise, - environmental impacts on the aquatic habitat andcreation of enclosed waters, - water quality impacts of silting and trapping ofstorm water discharged from CSOs, - and long-term maintenance, inspection, and moni-toring.

P R O P O S E D D E M O N S T R A T I O N P R O J E C T2) Inter-tidal wetlands and floodable uplands wouldbe configured to support low and high marsh vegeta-tion beginning along the -2' NAVD88 contours under-water and sloping upward to the existing shoreline.The floodable uplands could be designed as park-lands, but dredged material is not proposed to beused. It is anticipated that the wetlands would pro-vide wave attenuation and slow down the advance ofstorm surge.

Questions that would need to be answered before afuture demonstration project with wetlands couldmove forward include: - the value and effectiveness of wetlands for coastalprotection on a working waterfront where propelleraction ("prop wash") and wakes are common,

- costs of mitigation for loss of in-water habitat andfilling of open water,- shifting of geotextile bags during storm conditionsand subsequent release of loose dredged materials, - interference with navigation and existing mar-itime/industrial businesses,- duplication of the PANYNJ's ongoing wetlandrestoration projects in Jamaica Bay, - coordination with wetland projects in the US ArmyCorps of Engineers and PANYNJ's ComprehensiveHarbor Restoration Plan, - environmental impacts on shallow water habitat, atarget eco-system, - and long-term maintenance, inspection and moni-toring.

DREDGED MATERIALS & CLIMATE CHANGE PILOT3) On-shore berms were proposed to rise to +11'NAVD88 and be placed directly behind the shorelineelements. These would rise 5' above existing gradesat their highest level. Flood drains would allow fordrainage of stormwater from the landward side to theharbor. The berms would not provide protectionagainst the FEMA 100-year flood (at +12' NAVD88 inthis area), however they are anticipated to protectagainst more frequent storms with lower flood levelsand against sea level rise.

Issues that would need to be addressed before afuture demonstration project with berms moves for-ward include:- the value of berms for coastal protection on a work-ing waterfront where access to vessels is required(versus, for example, deployable floodwalls) at theshoreline,

- access to existing businesses and water-depend-ent uses, - height of the berm relative to FEMA standards, - height of the berm relative to view corridors andpublic access to the waterfront, - scalability for sea level rise, - anchoring systems to prevent displacement duringstorms and undermining by wave action, - the "bathtub effect" and drainage in the event ofovertopping or heavy inland rainfall, - integrating the berm into future development thatmay require public access and an esplanade, - coordination with the integrated flood protectionsystem proposed to be set inland in NYC's PlaNYC:A Stronger, More Resilient New York, - and long-term monitoring, maintenance andinspection.

P R O P O S E D D E M O N S T R A T I O N P R O J E C T4) Reconstruction of Pier 44 was proposed to extendthe existing short pier offshore along its historic foot-print, which was once approximately 600' long. It isbelieved that the original pier was constructed with asolid core center made of stone flanked by timberpier extensions along the sides to allow for berthingof vessels. Reconstruction of Pier 44 is anticipatedto have a similar "groin" function, reducing floodingand adjacent shoreline erosion.

Questions that would need to be answered before afuture demonstration project with reconstruction ofPier 44 could move forward include:

- the value and effectiveness of the pier/groin inreducing flooding and erosion, - costs of mitigation for loss of in-water habitat andfilling of open water,- ensuring public access while enhancing maritimeuses and creating new habitat, - coordination with NYC and NYS flood protectioninitiatives,- anchoring the dredged materials and technologyto withstand storm surges,- and long-term monitoring, maintenance andinspection.

Estimated Costs

Preliminary cost estimates for each of these ele-ments were prepared by the technical consultingteam and include material, delivery and constructioncosts. Not included in these estimates, however, arecosts for permitting, data collection, design, sitepreparation, construction of upland staging areas,installation of utilities, post-construction monitoring,or post-construction operation and maintenance.

NEXT STEPS

The next steps on the Dredged Materials &Climate Change Pilot Project will be to build onthe work completed in Phase 1, raise additionalfunding for Phase 2, and further develop the pro-posed demonstration project. Consultation withthe key agencies and community stakeholders toensure feasibility of the demonstration projectand its value to the ongoing regional recoveryfrom Hurricane Sandy is critical. In addition,continuing collaboration with the property ownerwill be an important component of the success ofPhase 2.

Coordination with NYC, NYS and FederalAgencies and Community Consultation

Consultation with the Project Advisory Group hasbeen ongoing throughout the first phase of thepilot project. Before proceeding to Phase 2, moredetailed pre-application consultations are need-ed with the US Army Corps of Engineers andNew York State Department of EnvironmentalConservation, the key permitting agenciesinvolved. In parallel, coordination with the manyNew York City and State initiatives in progresswill be required to ensure that this pilot projectaligns with and supports those public invest-ments. Among those initiatives is New YorkRising, the NYS Department of State'sCommunity Reconstruction Program (CRP). ThePANYNJ will continue to consult with Red Hook'sCRP along with the Community Boards in bothRed Hook and Sunset Park.

Hurricane Sandy has made us look atthings differently in Red Hook.

We know our businesses, as well as ourwaterfront neighbors and the larger com-munity, are going to need more protectionduring future storms and more preparation

for sea level rise.

We are excited about the Port Authority'sclimate change pilot because it ties in withour own vision of Red Hook's waterfront:

to open up the area and invite people to visit and enjoy it. We're proud of our

working waterfront and maritime buildings,especially as part of this growing and vibrant mixed-use comunity.

This pilot will help protect Red Hook from climate change while also increasingpublic enjoyment of the waterfront, con-serving and adding to existing habitats,and continuing to develop our dynamic

and resilient community.

Funding

While the project funding through the Bi-StateDredging Funds includes seed money for thenext steps, it is a relatively small portion of thecosts of moving forward with this demonstrationproject. A variety of other potential sources offunding will need to be explored including pub-lic/private investments.

Collaboration with the Property Owner

Continued collaboration with the property owner,The O'Connell Organization, will be important.They have been part of the revitalization of RedHook and a leader in its economic developmentand job creation. They have helped open up thearea and provide waterfront walkways and out-door spaces for people to enjoy. The O'ConnellOrganization's objectives for this property alignwith the project goals and their track record inthis location over many decades is widely-praised.
