Hurricane Sandy (October 2012)

Hurricane Sandy
Hurricane Sandy left an indelible mark on Long Island. From the devastation of flooded neighborhoods to the weeks-long power outages and the costly rebuilding that followed, Sandy reshaped how Long Islanders think about coastal living and disaster preparedness. Today, the storm’s legacy continues to influence policies, infrastructure, and community resilience across Nassau and Suffolk Counties. File photo: Cathy Kovarik, licensed.

Hurricane Sandy, often referred to as “Superstorm Sandy,” was one of the most devastating natural disasters to ever strike Long Island and the greater New York metropolitan region. Making landfall in late October 2012, Sandy caused unprecedented flooding, widespread power outages, and billions of dollars in damage. The storm forever changed coastal communities, infrastructure, and emergency preparedness across Nassau and Suffolk Counties.

Timeline of the Storm

  • Formation: Sandy formed in the Caribbean on October 22, 2012, strengthening into a Category 2 hurricane.
  • Northeast Approach: By October 29, Sandy had merged with a cold front, creating an enormous storm system that expanded nearly 1,000 miles wide.
  • Landfall: Sandy officially made landfall near Atlantic City, New Jersey, on the evening of October 29, 2012, but its effects were felt across Long Island at full force.
  • Peak Impact on Long Island:
    • Storm Surge: 9–12 foot storm surges battered the South Shore.
    • Wind Gusts: Winds exceeded 80 mph in parts of Long Island.
    • Tides: Record-breaking high tides flooded coastal neighborhoods, especially in Nassau County.

Impact on Long Island

Coastal Flooding

  • South Shore communities such as Long Beach, Freeport, Island Park, Massapequa, Lindenhurst, Babylon, and the Rockaways were inundated with seawater.
  • Barrier islands including Fire Island and Jones Beach saw extensive dune erosion and infrastructure damage.
  • Homes, marinas, and boardwalks were destroyed or severely damaged.

Power Outages

  • Over 90% of Long Island Power Authority (LIPA) customers – more than 1 million homes and businesses – lost electricity, some for weeks.
  • Downed power lines and blocked roads made restoration efforts extremely difficult.

Transportation Disruptions

Economic & Property Damage

  • Total estimated damage in New York State exceeded $40 billion, with a large share from Long Island.
  • Thousands of homes required major repairs or were condemned.
  • Small businesses along the South Shore faced massive losses from flooding and extended closures.

Human Toll

  • Dozens of Long Islanders lost their lives due to storm surge, falling trees, or medical emergencies exacerbated by the disaster.
  • Tens of thousands were displaced, with some families relocated for months.

Emergency Response & Recovery

  • Evacuations: Mandatory evacuations were ordered in flood-prone zones, including barrier islands and waterfront neighborhoods.
  • Relief Efforts: FEMA, the National Guard, Red Cross, and countless volunteers provided food, shelter, and recovery assistance.
  • Community Resilience: Local fire departments, police, and neighbors worked together to conduct rescues, distribute supplies, and begin cleanup.
  • Restoration Projects: Federal and state funding supported rebuilding boardwalks, reinforcing dunes, and elevating homes in flood zones.

Long-Term Effects on Long Island

Infrastructure Changes

  • Power System Reform: Outrage over LIPA’s storm response led to reforms and the creation of PSEG Long Island to manage the power grid.
  • Transportation Upgrades: Coastal roads, tunnels, and train systems have since received flood-protection improvements.

Housing & Building Codes

  • Stricter building codes now require many homes in flood zones to be elevated.
  • FEMA flood maps were updated, changing insurance requirements for thousands of homeowners.

Environmental Impact

  • Sandy accelerated coastal erosion along Fire Island and other barrier beaches.
  • Restoration projects, including dune rebuilding and wetland preservation, remain ongoing.

Lessons Learned

Hurricane Sandy underscored Long Island’s vulnerability to coastal storms and rising sea levels.

  • Preparedness: Local governments and residents are now more proactive about emergency planning.
  • Resilience: Investments in stronger power systems, better communications, and improved flood defenses continue.
  • Community Spirit: Sandy demonstrated the strength of Long Island’s communities, with neighbors and organizations rallying to rebuild together.
