Strengthening the Shoreline

Nature’s first line of defense against erosion caused by wave energy, storms, wind and run off is under stress. Rising sea levels and increasingly warm waters are generating storms of greater frequency and severity in the Northeast that decimate our shorelines, producing unpredictable flooding in the region. The tri-state’s harrowing experience with Superstorm Sandy as well as heavy rains this past hurricane season previewed the threat, which most climatologists believe will intensify due to both climate change and cyclical weather systems that predict a particularly stormy period in the decades ahead.

Protecting the shoreline and surrounding communities is a complex problem, and one that engineers and environmental experts at Nelson + Pope/Nelson Pope Voorhis (NPV) have been tackling along Long Island’s north and south shores. From jetty restoration to numerous drainage improvement projects funded by the New York State Governor’s Office of Storm Recovery (GOSR), each project has its own set of considerations: existing conditions, proximity to nearby developments, impact on the marine ecosystem, and land and water use requirements.

Mount Sinai Jetty Restoration
Constructed during the late 1930s to stabilize the mouth of the Mount Sinai Harbor from active gravel mining, the harbor’s east and west jetties experienced significant collapse over time, leading to navigational hazards and shoaling (shallowing) of the inlet. For years, both structures have been largely submerged at high tide, causing beach erosion on Port Jefferson’s East Beach and allowing water and sand to leak through and settle in the mouth of the harbor. In addition to creating issues for beachgoers and boaters, marine life was impacted due to the harbor’s inability to flush out to Long Island Sound.
Acting on a report by the U.S. Army Corps of Engineers (USACE), Nelson + Pope performed topographic surveys of the jetties and contracted for bathymetric surveys of the inlet to determine water depth and underwater inspections. Recommended design included full replacement of the jetties, raising their crest elevations and repositioning the west jetty to match current shoreline conditions, as well as other improvements critical to coastal health. Nelson + Pope prepared plans and provided construction inspection services for the jetties reconstruction and also for dredging of the inlet, beach nourishment using dredged sand, and reconstruction of the Cedar Beach Fishing Pier alongside of the east jetty. NPV provided permitting services for all phases of the project.

Green + Gray Solutions
For combating shoreline erosion, evidence suggests that softer “green” solutions that mimic nature, such as bioswales and deep-rooted indigenous plantings, when applicable, are more effective than harder “gray” solutions, such as bulkheads and breakwaters. In a perfect world, we would revert to nature’s original state, but reality dictates both green and gray solutions for the developed world.
An example of this multifaceted approach is the Town of Babylon’s Shoreline Stabilization and Roadway Improvement project. The project included measures to reduce erosion and prevent further collapse of Oak Beach Road, a single-entry road serving 189 residential structures that became impassable due to flooding during storm events. Providing design and construction management services, Nelson + Pope’s design called for raising and re-pitching the roadway to direct runoff into a bioswale area in the vegetated shoulder. A combination of hard and soft features were incorporated, including a bulkhead on the seaward side with landward wetland vegetation, a stone revetement, and a vegetated berm with turf-reinforced matting to provide stability in the event of a storm surge overtopping the bulkhead. NPV provided coordination with environmental agencies including USACE, New York State’s Department of State and Department of Environmental Conservation.
Currently in construction, Island Park’s Destination Revitalization and Transit Oriented Development Pilot Project specifically focuses on streetscapes, with the goal of transforming the site to a safe and pedestrian friendly destination. The Nelson + Pope-designed project employs green infrastructure solutions and reinforced concrete pipes to improve drainage, as well as many roadway and crosswalk improvements to increase safety and achieve ADA compliance.

LiDAR Achieves Survey Accuracy, Efficiency
Advances in land surveying techniques from the air and on the ground are improving the speed and efficiency of obtaining accurate data, particularly for projects with complex environments. At Nelson + Pope, our team is finding increasing uses for one such technique, Terrestrial LiDAR Surveying, on challenging projects like the Northville Industries Corp. Terminal in Holtsville, a 15-acre site housing 14 million barrels of fuel in numerous tanks connected by a mass of pipe. 

Ground-based Terrestrial LiDAR (Light Detection and Ranging) Surveying uses light in the form of pulsed lasers to measure objects at variable distances, producing highly accurate 3D data through a laser scanner.  With the scanner mounted on a tripod, a small team can survey industrial facilities, infrastructure, town centers, and other sites of interest. The scanner accurately measures and collects detailed point clouds; with point cloud processing software, these datasets generate digital 3D models of the scanned environment.

At the Northville Industries location, Nelson + Pope was tasked with surveying all appurtenances on-site, including all above ground and underground utilities with a full topography of the ground. “Conventional survey of the piping alone would have been confusing to draft,” says Senior Partner Greg Peterman, “and the field measurements would have taken at least a week of field survey time to accurately locate. By using LiDAR technology, we were able to scan the entire 15 acres in only 2 days and generate a point cloud showing the piping and structures, which made it easy to decipher and map all required appurtenances and resulted in significant cost savings to the client."

West Islip Long-Term Pump Station Generators
Nelson + Pope provided design for a storm resilient generator at two sites in West Islip that required locating the generator, power and controls equipment above the 500-year flood elevation. Sited adjacent to residential properties, pump station aesthetics and noise issues were of particular concern.

DRI Grant Strategy & Writing Services
Congratulations to the Villages of Haverstraw and Ossining on each receiving $10 million through New York State’s Downtown Revitalization Initiative (DRI). NPV is honored to have had a critical role on the team that prepared the application for funding to jumpstart downtown redevelopment in these communities. See More
Heart & Health Ambulatory Center
Nelson + Pope provided architecture and interior design for a new 4,000 sq. ft. AAAASF-certified surgery center specializing in vascular surgery and hyperbaric treatment.  Designed to meet the most stringent healthcare regulations imposed by Article-28 standards of the New York State Department of Health, this interior gut alteration provided two operating rooms, clinical exam rooms, piped-in medical gases and two hyperbaric oxygen therapy chambers.  Read More 
344 Duffy Avenue, Hicksville
Now the site of a new 195,000 sq. ft. Home Depot Distribution Center, this
9-acre site was once mined for sand and subsequently used for construction and demolition debris. In addition to addressing the potential impacts of prior uses, required improvements include a 180-stall parking lot, 30-bay concrete truck loading area, connection to public water/sewer and onsite drainage.

Carrie is a senior partner and manager of NPV’s Environmental Resource and Wetlands Assessment Division in the firm’s Long Island Office. A trained environmental scientist with 20 years of applied planning experience, she is an expert in NEPA/SEQRA and land use regulations, drainage and stormwater issues, wetland and stormwater permitting, and environmental planning analysis. Growing up in Western New York with limited exposure to the ocean, Carrie fell in love with the diversity of Long Island’s coastal environment when she relocated there two decades ago. In addition to her work with municipalities and property owners to restore, enhance and protect the shoreline, Carrie and her family spend as much time as they can on the waterfront, boating, paddle boarding and searching for waves.
