Safely shutting off utilities

Even a few inches of rain can cause extensive damage in your home. Take steps now to protect your valuables.

  • Keep a record of your personal property for insurance purposes.
    • Take photos or a video of the interior and exterior of your home and your most valuable possessions. Include household possessions (including model and serial numbers) and personal belongings in your inventory.

  • Store your inventory and documents such as insurance policies, deeds, property records, passport, birth and marriage certificates, social security cards, wills, bank and financial information and other important papers in a safety deposit box away from your home. Make copies of important documents for your disaster supplies kit.
  • It is advisable to keep a small amount of cash or traveler’s checks at home in a safe place that you can quickly access in case of evacuation.

Consider buying flood insurance now

Flooding causes more than 90 percent of all disaster-related property damage in the United States but most homeowner policies do not cover flood damage. Because of this, we recommend purchasing flood insurance.

The County of Hawai‘i participates in the National Flood Insurance Program (NFIP), enabling residents to purchase flood insurance with discounted premiums.

Contact your insurance agent or call NFIP, 1-888-379-9531.
