Coastal Storm Risk Management Projects

In New York State, Coastal Storm Risk Reduction Projects are constructed through a three-way partnership. The U.S. Army Corps of Engineers is the federal partner, DEC is known as the "Non-Federal Sponsor" and the local municipality is the project's Local Sponsor. These projects are typically cost shared between the three parties (Federal, State, and local), but under certain circumstances the Federal government may undertake these projects at a 100% Federal expense. DEC works with the Army Corps of Engineers and the Local Sponsor to bring these projects from the study phase through construction to completion. As the Non-Federal Sponsor, DEC is tasked with responsibilities such as reviewing the scope of work, plans, environmental reports, coordinating with the Local Sponsor, interfacing with the public and providing the necessary real estate for project construction. These responsibilities vary by project and are laid out in agreements signed before the beginning of each phase of the project.

DEC is currently involved in two Coastal Storm Risk Reduction Projects:

  1. Long Beach Contract #2-Crossovers and Beachfill
  2. South Shore Staten Island Coastal Storm Risk

Long Beach Contract #2 - Crossovers and Beachfill - last updated 1/30/20

Construction associated with Contract 2 of the US Army Corps of Engineers Long Beach Island Storm Damage Risk Reduction Project has officially begun in the City of Long Beach. It started in Long Beach because the contractors cannot work from the eastern City limit to Point Lookout until after September 1, due to the Piping Plover environmental restrictions. The work consists of installing new dune crossover structures to access the beach from the boardwalk and then building a new dune south of the boardwalk and adding sand to the beach to make it larger. Once the sand is placed, the dune will be fully planted and sand fencing will be installed at both the seaward and landward toes of the dune to protect it.

The first order of work is to install the piles in the City of Long Beach that will provide the support for the new dune crossover structures connecting the boardwalk to the beach. Before the piles could be driven, the contractor dug "test pits" in the sand; this was done because several of the old timber groins that run perpendicular to the boardwalk are still below grade in the same locations as the new crossovers. By digging these test pits, the contractor was able to shift and reposition the new piles as necessary without having to remove the old timber groins which are still acting to hold the sand on the beach.

See Status section below for a list of street ends from west to east that will be getting a new crossover structure off the boardwalk. In almost all cases, the new crossover will be adjacent to the existing beach access ramps, and the existing ramps will not be demolished until the new one is complete. The number in the parentheses indicates the order in which the piles will be installed. The order of pile installation was determined with a couple of factors in mind; the Corps is trying to minimized the impacts during the summer months in the most populated and recreationally important parts of Long Beach, and the pile installation needs to stay several weeks ahead of the dredge as the sand cannot be placed until the piles are installed.

There will be two sizes of crossovers in the City. At New York, National, Riverside and Neptune, the bridges over the dune will be 30 feet wide. The rest of the bridges over the dune will be 10 feet wide. All of the ramps going down to the beach from the bridges will also be 10 feet wide. Depending on the size of the crossover, it will take the contractor approximately three to five days to install all the piles before work moves on to the next crossover. This work will be done Monday through Friday from 8:00 AM to 4:00 PM and the order of work is subject to change due to mechanical/weather delays. The pile installation is a much shorter duration per location compared to the stone and groin work where the contractor was in one location for four to six weeks at a time. Vibration monitors have been installed by the contractor near the pile installation locations.

Once the piles have been installed and the sand placed around them, the contractor can come back and install the bridges and ramps and then remove the existing beach access ramps off the boardwalk. We do not have a schedule for this work at this time.

Beachfill and Dune Placement

The contractor has landed the first shore pipe east of New York Avenue and will start pumping per the schedule in the Status section. Just like with the pile installation, this schedule is subject to change due to mechanical/weather delays.

Beachfill operations have also begun with the dredge arriving in Long Beach on July 4 and the contractor assembling the dredging pipe to reach the shoreline. The dredge is basically a very large vacuum cleaner that will suck clean sand off the ocean bottom and pump it through the large pipe onto the beach. The sand will then be shaped into the beach and dune design template by bulldozers. Pumping of the sand is expected to begin July 13. As of July 2018, sand placement will be a 24 hour a day/7 days a week operation. At this pace, the contractor can complete about 200 feet of beach a day (this includes widening and raising of the beach and the new dune).

Where pipe is laid out on the beach, 10-foot-wide ADA compliant sand ramps with stabilization mats will be installed every 500 feet along the beach so pedestrians can walk over the pipe safely and walk down to the water. The contractor will have a "moving" 1,000 foot working area that will be fenced off with appropriate warning signs installed, with fencing being moved in the early morning as the work proceeds down the beach. Sand fill will be completed in 500-foot segments and once a new section of beach is complete, it will immediately be opened for public use. At first, the sand will be slightly darker than the existing sand as it will still be wet from being pumped from the ocean bottom; but in a matter of weeks the sand will bleach out and assimilate nicely with the existing beach sand.

Decking Installation

There will be three crews in total: one installing the decking, one installing the railings, and one installing the hand rails. For safety reasons, crossovers will only be made available for public use once all three crews have completed their work at a crossover. The Ipe wood decks for the City's four 30-ft.-wide crossovers (Riverside, National, Neptune, and New York) have arrived and the contractor has begun installing them, beginning with Riverside and Neptune.

The rest of the decks are scheduled to be delivered to the project site by mid-January. The contractor will install as many decks as possible in the Town of Hempstead/Lido Beach/Nassau County/Point Lookout area before the bird window restrictions start on April 1. It is expected that the contractor can complete eight crossovers before April 1. In coordination with the Town of Hempstead and Nassau County, DEC has provided the contractor with the order of work for these crossovers, as seen below. The schedules will be updated on the website as information becomes available.

South Shore Staten Island Coastal Storm Risk Management Project

The goal of this project is to reduce the risk of damages from coastal flooding and flood damage from rainfall, as well as managing risk to local residents' life and safety.

Project Elements

The project consists of three typical structures, with a length of ~5.5 miles, and a top elevation of +20.5 feet National Geodetic Vertical Datum (NGVD) of 1929.

  • Reaches A-1 and A-2: Earthen Levee (~3,400 ft.) with a crest width that ranges from 10 - 15 feet. The Levee ties into high ground northwest of Hylan Boulevard.
  • Reach A-3: Vertical Floodwall (~1,800 ft.) that is pile supported with a T-shaped concrete floodwall.
  • Reach A-4: Buried Seawall (~23,700 ft.) with a 10 - 18 ft. wide crest. The seaward and landward faces of the above ground portions of the Seawall will be covered with soil and planted with native beach vegetation. It will tie-in to high ground near Fort Wadsworth.
    • A promenade will be constructed atop the entire length of the Buried Seawall extending from Oakwood Beach through Miller Field and ending near Fort Wadsworth (~4.5 miles), as shown in the renderings below.

Road raising and interior drainage features will be constructed throughout the project to provide tie-ins to high ground and to allow proper drainage for stormwater. A new tidal wetland will be constructed in the Oakwood Beach area seaward of the Buried Seawall.

The South Shore of Staten Island Project has been developed to provide a level of protection from coastal flooding such as that during Superstorm Sandy for the inland communities along the South Shore of Staten Island. The Project includes the use of drainage structures, seawalls, levees, and revetments for approximately seven miles of Staten Island from the Verrazano Bridge to Oakwood Beach. The U.S. Army Corps of Engineers (Corps) is the Federal sponsor for the project, with DEC as the Corps' Non-federal Sponsor, and City of New York as the Local Sponsor.

The project is currently in the engineering design phase which is anticipated to be completed by the fall of 2019. Subsurface investigations and borings to assist in designing the foundations of the seawall are currently ongoing. This work is anticipated be completed by the end of 2018 and will also identify any obstructions that may require the final alignment of the seawall to be adjusted. The actual design and layout of the seawall will begin as the results of these subsurface investigations are completed. Construction will be done in multiple contracts with the first contract expected to be bid out and started in 2020 with work being completed in 2023.

In order to actually bid out the construction contracts the Corps, DEC, and City need to enter into legal agreements which should be executed within the timeframes necessary to keep the project advancing on schedule. The current estimate for the project cost is $615,000,000. The source of funding for this project is 65% Federal, 24.5% State, and 10.5% City. All three government entities have their portion of funding available to move forward with construction.

The Corps maintains a webpage that contains significant information, along with numerous project documents (leaves DEC website).
