This is what policyholders paid, not a quote. Two neighbors can pay very different prices: NFIP prices depend on the building (elevation, foundation, number of floors, replacement cost), the coverage and deductible chosen and the distance to water (FEMA FloodSmart: premium factors). For a price for your building, ask an insurance agent. Private flood insurance is not included in these figures.
