The updated maps, known as Pending Flood Insurance Rate Map databases, are being updated to grade the level of flood risk as the agency updates the map across the country. “They look at those high-risk areas and what the frequency and severity is of those flood plains.” Johnson said.
The spectrum of risk ranges from “undetermined”, “to moderate”, to “high risk.” He says no properties in Houston are listed as “no risk”. The severity of the risk of flooding will dictate whether the mortgage lender will ask the homeowner to add flood insurance to their policy, as some properties will not require it. Johnson said it is unknown if the zoning will affect insurance rates.
Residents are encouraged to review the updated flood hazard data.
Officials are asking homeowners to contact their local floodplain manager to review how the changes could impact development plans, property values, or insurance costs.
