§ 7-5-8 FLOOD INSURANCE.

   Floods from storm drainage may occasionally occur which exceed the capacity of storm drainage sewer facilities constructed and maintained using funds made available under this code. This code does not imply that property liable for the rates and charges established in this code will always be free from storm drainage flooding or flood damage. This code does not purport to reduce the need or the necessity for the owner obtaining flood insurance and protecting the owner’s property from storm drainage.
