West Pond Breach and Trail Repair
Gateway National Recreation Area, Jamaica Bay Unit, West Pond
National Park Service
OverviewWest Pond is one of the most popular
sites withinGateway National Recreation Area and is
a local,national, and international destination.
• West Pond is 44 acres, 3 - 6 feet deep.
• 1.5 mile loop trail, Visitor Center.
• West Pond provides opportunities for birding, walking, and environmental education.
• Average yearly visitation over 575,000 pre-Sandy.
• Over 5,400 school groups from 2010-2015.

Pre-Sandy Conditions• Despite a long history of intense development, Jamaica Bay is rich
in fish and wildlife communities, with large and diverse populations of resident and migratory species.
• Jamaica Bay is recognized by the U.S. Fish and Wildlife Service as valuable habitat for migrating birds along the Atlantic. Some of these species have special regulatory protections under the Endangered Species Act, Migratory Bird Treaty Act, and state-level protections.
• The U.S. Fish and Wildlife Service estimates that nearly 20% of North America’s bird species migrate through or breed in the Jamaica Bay area.
• The West Pond freshwater wetland habitat of pre-Sandy conditions, unique and rare within Jamaica Bay, was a significant factor in the diversity of species.

Freshwater WetlandsIn the past century, over 90% of the freshwater wetlands in NYC have been lost. (NYC Wetland Strategy, May 2012; plaNYC A Greener, Greater New York)
• Freshwater wetlands provide important ecological, economic, and social benefits.
• Wetlands are among the most biologically productive ecosystems in the world; improve water quality by aiding in the retention of stormwater; and provide a buffer from storm surges.
• Wetlands attract wildlife for viewing and otherwise enhance the enjoyment of parks and public spaces. These open spaces are particularly highly valued in the dense urban area of NYC.
• Wetlands are destinations for educational programming and hands-on learning.

Hurricane Sandy • West Pond was breached and inundated with sea water from
Jamaica Bay, which has continued to increase salinity, create tidally influenced conditions, and change the habitat composition from brackish to more saline conditions.
• The existing breach continues to widen and is vulnerable to future damage from storm activity and erosion.

Storm Damage
Post-Hurricane Sandy• Currently, due to the loss of the freshwater wetlands, the West
Pond does not provide habitat that supports the diversity of species that existed pre-Sandy.
• Loss of the loop-trail affected the visitor use and experience.
• Although the West Pond area continues to provide excellent habitat for shorebirds, waterbirds with freshwater associations have declined.
• National Audubon Society and Cornell Lab of Ornithology data from 2011-2014 show a decline in species since the breach to West Pond.
• Visitation numbers for the Jamaica Bay Wildlife Refuge have dropped significantly since Hurricane Sandy.
• A 37% reduction in visitation occurred between 2011 and 2014. 8

ResiliencyCurrent Work:Will provide resiliency.• Improved structural stability of pond embankment and
loop trail system.• Repairs to breach will reduce surface erosion at
breaches.• Restores the capability to manage water surface
elevations for optimum depth within the pond and reduces site specific flood risk.
• Designed to be inundated and overtopped on occasional storm events.
• Water control structure and water source decrease recovery time after inundation
• Includes design for shoreline restoration
Future Work:Will enhance resiliency.• Shoreline restoration would improve resilience. 12
