The flood insurance policy of the National Flood Insurance Program (NFIP) provides limited coverage for expenses you incur trying to protect insured property from flood damage. The policy language is quoted below. You should ask your insurance agent specific questions about actions for which you could expect to receive a claim payment and what documentation would be required.
Coverage C2 - Loss Avoidance Measures
a. Sandbags, Supplies, and Labor
(a) Your reasonable expenses to buy:
(i) Sandbags, including sand to fill them;(b) The value of work, at the Federal minimum wage, that you or a member of your household perform.
(ii) Fill for temporary levees;
(iii) Pumps; and
(iv) Plastic sheeting and lumber used in connection with these items.
This coverage does not increase the Coverage A or Coverage B limit of liability.
b. Property Removed to Safety
Any property removed, including a moveable home described in II.6.b. and c., must be placed above ground level or outside of the special flood hazard area.
This coverage does not increase the Coverage A or Coverage B limit of liability.
