Resiliency
Constructing coastal flood barriers, storm surge protection walls, and climate-resilient urban infrastructure safeguarding communities.
Bringing knowledge and foresight to every project
Coastal Storm Surge Barriers
Engineering deployable flood gates, coastal seawalls, and elevated flood protection barriers designed to withstand 100-year storm surges.
Subterranean Stormwater Retention
Constructing large-diameter deep storage tunnels and underground retention vaults to prevent urban flash flooding.
Critical Infrastructure Hardening
Retrofitting sub-stations, transit tunnels, and hospital mechanical plants against severe weather and rising sea levels.
Nature-Based Living Shorelines
Combining engineered armoring with living berms, restored wetlands, and permeable waterfront parks to absorb flood energy naturally.
Project spotlight: East Side Coastal Resiliency (ESCR) Project, New York
SNS Construction engineered a 2.4-mile floodwall barrier system, deployable flood gates, and raised parklands along Manhattan's East River to protect 110,000 residents from sea level rise and storm surges.
