The president arrived at the small New Jersey airport and was met on the tarmac by state governor Phil Murphy
The president arrived at Central Jersey Airport in Hillsborough Township shortly after 11.30am on Tuesday.
On exiting Marine One, Mr Biden was met by New Jersey Governor Phil Murphy, First Lady Tammy Murphy and several local leaders.
The president, wearing aviators on a sunny, 80-degree day in the Garden State, spent roughly 10 minutes chatting on the tarmac with the small group.
He did not take questions from press gathered at the airport before leaving by motorcade for the Somerset County Emergency Management Training Center.
The president is scheduled to visit the town of Manville where severe flooding impacted homes and caused several explosions.
He will then travel to the borough of Queens, New York where at least 11 people drowned in basement apartments after being trapped by gushing floodwater.
Mr Biden declared major disasters in New York and New Jersey this weekend, channelling federal aid to help with recovery from the storm.
The federal assistance can include grants for temporary housing and home repairs, the White House said in a statement, along with low-cost loans to cover uninsured property losses, and other programmes to help individuals and business owners recover from the effects of the disaster.
The remnants of powerful Orkanen Ida barrelled across the northeast last week bringing historic levels of rainfall and tornadoes. The storm killed at least 27 people in New Jersey and 13 i New York City.
I det minste 50 people were killed across six eastern states as some areas received a month’s worth of rain in a matter of hours.
The deluge overwhelmed rivers and decades-old sewer systems. Most of those who died were trapped in basement homes and vehicles, becoming swept away as they tried to escape.
A huge clean-up is underway as abandoned vehicles were towed and water pumped from submerged highways and public transit systems. Residents hauled the ruined contents of their homes onto streets and business owners got to work clearing muck and debris.
New York Governor Kathy Hochul reported that Ida damaged more than 1,200 homes and caused about $50m in damage to public infrastructure and property, following an initial assessment. Jersey City Mayor Steven Fulop said damage to city infrastructure was estimated at $35m.
The White House disaster declarations cover Bergen, Gloucester, Hunterdon, Middlesex, Passaic and Somerset counties in New Jersey and allow for individual assistance for people in Bronx, Queens, Kings, Richmond and Westchester counties in New York.
Governor Murphy said that he would discuss with President Biden the possibility of expanding the federal aid to more counties.
Governors from affected states underlined the role that the climate crisis played in exacerbating the extreme event.
“What I’ve seen in my last seven years are these localised storms, storms that actually in some cases occur outside of flood plains and that cause a lot of damage,” Pennsylvania governor Tom Wolf told CNN on Friday.
"Du vet, it’s climate change.”
The climate crisis is creating conditions which are driving more powerful storms like Ida.
Selv om det er uklart om klimakrisen vil bety et større antall orkaner i fremtiden, forskere har lenge advart om at økt global oppvarming sannsynligvis vil gjøre stormene vi opplever mer ødeleggende.
Havet absorberer over 90 prosent av overskuddsvarmen forårsaket av klimagassutslipp - hovedsakelig forårsaket av forbrenning av fossilt brensel - og at varmt vann strømmer inn i orkaner.
Og når planeten varmes opp, mer fuktighet holdes i atmosfæren, noe som betyr at stormer holder potensialet for mye mer nedbør.
Den globale havnivåstigningen forverrer faren for stormflo. The sea level off New York’s coast is up to nine inches higher than it was in 1950.
Following Superstorm Sandy nearly a decade ago, New Jersey and New York spent billions of dollars improving flood defences. derimot, much has focused on protecting communities from coastal surge – not rainfall.
