Tips for Parish residents to lower their flood risk: 
* Learn your flood risk. Find out your flood risk by entering your address at FloodSmart.gov “Assess Your Risk.” Insurance agents can provide more detailed information and insurance options.
* Purchase a flood insurance policy. Most homeowners insurance does not cover floods and there is typically a 30-day waiting period before a policy becomes effective. If you already have a flood policy, remember: it needs to be renewed each year.
* Move important objects and papers to a safe place.  Store your valuables where they can’t get damaged.
* Conduct a thorough home inventory. Thorough documentation of your belongings will help you file your flood insurance claim. For more information, visit www.knowyourstuff.org.
* Reduce your flood risk through home improvements. Visit FloodSmart.gov to learn about ways to lower the risk of sewer backup, basement flooding and other flood-related issues.
* Plan for evacuation. Plan and practice a flood evacuation route, ask someone out of state to be your “family contact” in an emergency, and ensure everyone knows the contact’s address and phone number.
* Build an emergency supply kit. Food, bottled water, first aid supplies, medicines and a battery-operated radio should be ready to go when you are. Visit www.ready.gov for a disaster supply checklist.
