The updated floodplain designations could impose financial burdens on affected homeowners, particularly those required to purchase flood insurance. While some properties have been removed from the floodplain, others now face increased risks and insurance costs. However, Howard County residents benefit from a 25% reduction in flood insurance premiums due to the county's 'Category 5' status in FEMA's Community Rating System. Homeowners are advised to assess their flood risk and consider insurance options, even if not mandated.
