We live in a flood zone. Our insurance ws $1200 a year. We got an elevation certificate showing the elevation of the slab of the house. The height of the slab allowed us to carry flood insurance for lesser risk flood zone. The Elevation cert was done by a surveying company and only cost $275 and it dropped our flood insurance to about $350 a year. I am an idit for not having it done in the first 4 years we lived there.
