The federal government responded quickly in passing relief appropriation bills for the areas around the country affected by Hurricane Agnes. Over $3 billion in emergency funding was passed, which was reported as being twice as much money as the five largest previous disasters had been granted.
When Hurricane Agnes hit, flood insurance was extremely rare in New York. Of a reported $400 million in damages, only $5 million was covered by insurance. A few years after Hurricane Agnes, Congress made flood insurance mandatory for anyone using federally regulated mortgages living in designated flood zones.
With a lack of insurance payouts, most businesses and homes were rebuilt using low interest loans, grants, or other forms of emergency government relief. The Small Business Administration's Disaster Loan Program, created in 1953, offered loans to businesses and homeowners. Part of the loans would be forgiven after sufficient consistent payments.
Thousands of New Yorkers relied on HUD trailers for the next year or two as they rebuilt their homes. The Office of Emergency Preparedness created a "mini-repair" program from the Army Corps of Engineers to have engineers check homes for rehabilitation. For families whose homes needed just a fixed roof, repaired doors, working water, working electricity, and working gas service, this "mini-repair" program offered an alternative to HUD trailers.
