| Flood Facts|
Did You Know:
- Floods happen in all 50 states. Walnut Creek has experienced several flood events during the last 50 years. Much of downtown Walnut Creek flooded during a major storm event in 1958. More recently localized flooding occurred in 2002 and 2005 resulting in damage to homes and private properties.
- Walnut Creek and its tributaries drain over 146 square miles within central Contra Costa County. The primary flood hazard to residents comes from Walnut Creek through the downtown area, Tice Creek and tributaries to Grayson Creek in northwest Walnut Creek. Localized flooding, however, can occur in any location.
- Homeowner's insurance does not cover flood damage which can be caused by as little as an inch of water. Properties located within the Special Flood Hazard Area (SFHA) also referred to as the 100-year floodplain have 26% chance of experiencing flood during the life of a 30-year mortgage.
- If you live in a SFHA, your mortgage lender requires you to have flood insurance. Click here for more information.
- You are eligible to purchase flood insurance as long as your community participates in the National Flood Insurance Program. The City of Walnut Creek participates in the NFIP program and residents are eligible for some discount on the flood insurance rates.
- It takes 30 days after purchase for a policy to take effect, so it's important to buy insurance before the floodwaters start to rise.
- All claims and expenses of the NFIP program are funded by insurance premiums, not tax dollars. Read more facts by going to the FloodSmart website.
- Real-time rain gauge and stream gauge information is available at the Contra Costa County Flood Control District website.
