A recent study conducted by a consultant has updated where the Federal Emergency Management Agency (FEMA) designated flood-plain is around Rapid City and, as a result, over 200 homes no longer will need to pay for the mandated flood insurance. According to the Rapid City Journal, those remaining in the flood-plain area will need to continue paying the insurance. Though other houses that are still in the flood-plain don't mind making the payments for the protection, their location and added insurance cost does make them a less desirable place to purchase for any future buyer. To view the updated flood-plain map of the affected area, view the FEMA letter of map revision determination document.
