How to Make a Household Flood Plan for Coastal Flooding

Create a practical coastal flood plan with local alerts, evacuation routes, household roles, pet arrangements, emergency supplies, and insurance checks.

A good coastal flood plan tells everyone in your household when to leave, where to go, how to get there, and what to take. Check local evacuation instructions before a storm, choose a destination and backup routes, account for pets and anyone needing assistance, and leave promptly when officials advise. Do not wait for water to reach your home.

Find your local flood and evacuation information

Start by checking whether your home and regular destinations could be affected by coastal flooding, storm surge, rainfall flooding, or other local hazards. Use FEMA flood map resources, local emergency-management information, and your community’s current evacuation-zone maps and instructions. Maps help you plan; they do not guarantee that an area outside a mapped zone is safe. NOAA’s coastal preparedness guide says more than two-thirds of flood losses occur outside FEMA flood zones, a figure from its 2017 guide rather than a current annual measurement (NOAA Office for Coastal Management, coastal flood risk PDF).

Write down the local agencies that issue alerts and evacuation orders, how to receive their messages, and the nearest official shelter or other safe destination. National maps and guidance cannot determine your household’s evacuation zone or best route: those depend on your address, local roads, transport, and current official directions. Ask local emergency management about routes and transportation help if anyone in your household lacks a vehicle.

Choose where to go and how to get there

Pick a destination outside flood-prone areas, such as a friend or relative’s home, a hotel, or an official shelter. Confirm that it is available during an evacuation, accessible to everyone who will travel, and able to accommodate your pets if they are coming with you. Check local shelter rules and lodging arrangements in advance.

Quick Dam Water Activated 5ft Flood Barrier, Pack of 2
  • Water Activated Flood Barriers, Rated #1 in Flood Control
  • Grows to 3.5in high in minutes, just get them wet
  • Long, flexible design creates all sorts of shapes
  • Use to control, contain & divert flood water
  • Ready to use, no sand or labor needed

Write down a primary route and at least one alternative. Avoid roads likely to flood, and do not assume a familiar route will remain passable during a storm. If a household member cannot drive or needs accessible transport, arrange a realistic option before an emergency and ask local officials what assistance is available. Practice leaving with your kit, using the planned route when conditions are safe.

Assign household roles and a reunion plan

Make responsibilities specific and simple. For example, name who checks alerts, gathers medicines and documents, takes each pet, and assists children or anyone who needs support. Build in time for mobility needs, medical equipment, medication schedules, language needs, and animal care.

Choose a meeting place outside your neighborhood in case you become separated, plus an out-of-area contact everyone can call or message. Put the contact’s details and key addresses on paper as well as in phones. The American Red Cross family emergency plan guidance recommends agreeing on responsibilities, choosing meeting places and an out-of-area contact, and practicing parts of the plan.

Pack an evacuation kit and protect key information

Keep a kit where household members can reach it quickly. NOAA recommends at least three days of nonperishable food, water, and medicine for each person, and advises storing more than three days of water if possible. Tailor supplies to medical requirements, household size, and local emergency advice. NOAA also names a battery-powered radio, flashlights, extra cash, and a phone charger; FEMA’s flood information includes a first-aid kit, sturdy shoes, food, water, and a portable battery-operated radio (NOAA flood preparedness; FEMA flood information).

Photograph or make a video inventory of belongings before a flood threat. The National Flood Insurance Program recommends documenting possessions to support preparedness and possible claims (FloodSmart, the NFIP flood insurance resource). Specific radio reception and alert features vary by location, so check that any device works with local alert channels.

Write down alert meanings and leave-now rules

Record the alert channels you will monitor and what your household will do when an alert arrives. The Red Cross defines a flood or flash-flood watch as meaning flooding is possible, while a warning means flooding is occurring or expected soon and calls for immediate precautions (American Red Cross flood safety guidance). Coastal conditions and local alert terminology can vary, so follow the instructions issued by your local authorities.

If officials advise evacuation, leave for your planned destination before flooding begins. Do not wait to see water at the house or attempt to cross a flooded road. Never walk, swim, or drive through floodwater: the Red Cross warns that just 6 inches (15 cm) of fast-moving water can knock a person over, and 12 inches (30 cm) can carry a vehicle away.

What to do when flooding is predicted

  1. Monitor local emergency-management messages, weather alerts, news, and evacuation orders.
  2. Follow official evacuation instructions promptly; take household members, pets, medicines, and the kit.
  3. If there is time and it is safe, move documents and valuables to a higher place and take inventory photos.
  4. Do not let property-protection tasks delay departure, and never enter floodwater to retrieve belongings.

The NFIP’s predicted-flood checklist also advises monitoring alerts, moving valuables and documents higher, and taking a household inventory. Use those steps only when they do not delay evacuation.

Review flood insurance before storm season

Standard homeowners and renters insurance generally does not cover flooding; flood coverage is usually a separate policy. NOAA’s preparedness page reports a 30-day waiting period, but policy terms and eligibility can vary or change. Contact an insurer or agent well before a storm to confirm when coverage starts and to review covered property and contents, exclusions, limits, deductible, premium, and eligibility. NOAA’s hurricane preparedness guidance discusses flood insurance and the reported waiting period; verify the current terms directly with the provider.
