The Public Works Department is responsible for the design, construction, operation, and maintenance of all flood control facilities within D’Iberville. These facilities consist of: drainage pipes, catch basins, ditches, channels, ponds, pump stations, and numerous other infrastructure elements that seek to protect our town from flood damage.
Since homeowners or renters insurance polices do not cover losses due to flooding, the City strongly urges you to buy or continue your flood insurance to protect yourself from potentially devastating losses. D’Iberville participates in the National Flood Insurance Program (NFIP) and Community Rating System (CRS).
D’Iberville can experience flooding from both rain storms and tidal events. There are systems in place to help prevent and minimize damage and disruption from flooding, and some key elements are outlined below:
- A portion of D’Iberville lies within a Special Flood Hazard Area (SFHA), more commonly referred to as the “floodplain”. This SFHA consists of properties within zones AE and VE as delineated on a Flood Insurance Rate Map (FIRM) prepared by FEMA for our community. The FIRM can be viewed at the Public Works Department office, and assistance can be provided in determining if your property is within the SFHA.
- Associated with these zones is a Base Flood Elevation (BFE). This BFE represents the level to which a flood having a 1% chance of being equaled or exceeded in any given year (commonly called the “100-year” flood) will rise.
- The National Flood Insurance Program (NIFP) requires that D’Iberville examine the construction of all new structures, and the improvement, modification, or repair of existing structures that are located within the SFHA. Any new development or additions/renovations to an existing structure within the SFHA will require a “Floodplain Development Permit”
- In an effort to reduce flood insurance rates for our residents, D’Iberville participates in the FEMA / NFIP Community Rating System. Through our floodplain management efforts the town has reached a CRS Class 7, which translates to 10-20% savings on all flood insurance rates. This discount is set up to occur automatically for all current policies. However, to ensure that you are receiving this discount, ask your insurance agent when renewing or purchasing a flood insurance policy.
