Is there a different tax rate for property in 100 year flood plane?

Generally real estate located in a 100 year flood plain zone is not taxed at a different real estate tax rate. With flood insurance readily available at affordable prices, at least in the U.S., home buyers will pay as much for a home or business in a 100 year flood plain zone as comparable properties that are not located in flood-prone areas. Ask your local assessor in your area to be sure.
