Kauai Flood Zone Maps.

    Kauai Flood Maps and Zoning Explained in Layman Terms.

    We feel it’s always a good idea to talk to your insurance agent as well as the lender you are using when buying a property in any flood zone. Below I’ll map out some of the major flood zones on Island but first heres the legend.

    Here’s how I read it in layman terms.flood zones flooding kauai legend map north east south west hanalei kilauea princeville koloa lawai

    RED = Storm Waves

    GREEN = Sheeting Shallow Water

    (caused by flooding from another area spilling over)

    BLUE = Rising Water

    (from rivers and streams)

    Haena | Wainiha

    This map shows the North Shore of Kauai, West of  Hanalei. Virtually all of Haena and Wainiha are in the Red Flood Zone!

     

    Hanalei | Princeville | Anini Beach

    Hanapepe | Salt Pond

    maps mapping map Hanapepe Salt Pond Flooding Flood Zone zones south shore west side
    Hanapepe River provides lots of potential for flooding and sheeting water. Salt pond also gets lots of storm wave action.

     

    Waimea | Kekaha

    Waimea Town River Flooding West Side flood map zones zone
    Waimea is pretty flat and nearly level with the sea so lots of the commercial sector is in the floodplain.

     

    Here’s the legend spelled out:

    Zone A – is the flood insurance risk zone that corresponds to the 1% annual chance floodplains that are determined in the FIS by approximate methods. Because detailed hydraulic analysis are not performed for such areas, no base flood elevations or depths are shown within this zone.

    Zone AE – is the flood insurance risk zone that corresponds to the 1% annual chance flood plains that are determined in the FIS by detailed methods. In most instances, base flood elevations derived from the detailed hydraulic analysis are shown at selected intervals within this zone.

    Zone AH – is the flood insurance risk zone that corresponds to the areas of 1% annual chance shallow flooding with a constant water-surface elevation (usually areas of ponding) where average depths are between 1 and 3 feet. The base flood elevations derived from the detailed hydraulic analyses are shown at selected intervals within this zone.

    Zone AO – is the flood insurance risk zone that corresponds to the 1% annual chance shallow flooding (usually sheet flow on sloping terrain) where average depths are between 1 and 3 feet. The depth should be averaged along the cross section and then along the direction of flow to determine the extent of the zone. Average depths derived from the detailed hydraulic analyses are shown within this zone. In addition, alluvial fan flood hazards are shown as Zone AO on the FIRM.

    Zone A99 – is the flood insurance risk zone that corresponds to the 1% annual chance floodplain that will be protected by a Federal Flood protection system where construction has reached specified statutory milestones. No base flood elevations or depths are shown within this zone.

    Zone AR – is the flood insurance risk zone that corresponds to areas of special flood hazard that results from the decertification of a previously accredited flood protection system that is determined to be in the process of being restored to provide a 1% annual chance or greater level of flood protection.

    Zone AR/A; AR/AE; AR/AO; and AR/AH – are dual flood insurance risk zones that correspond to areas of special flood hazard that result from the decertification of a previously accredited flood protection system that is determined to be in the process of being restored to provide a 1% annual chance or greater level of flood protection. The dual zone designation indicates that some residual 1% annual chance flooding will occur after the levee system has been restored and is credited with providing 1% annual chance flood protection.

    Zone V – is the flood insurance risk zone that corresponds to the 1% annual chance coastal floodplains that have additional hazards associated with storm waves. Because approximate hydraulic analyses are performed for such areas, no base flood elevations are shown within this zone.

    Zone VE – is the flood insurance risk zone that corresponds to the 1% annual chance coastal floodplains that have additional hazards associated with storm waves. Base flood elevations derived from the detailed hydraulic analyses are shown at selected intervals within this zone.

    Zone X – is the flood insurance risk zone that corresponds to areas outside the 1% annual chance floodplain, and areas of 1% annual chance sheet flow flooding where average depths are less than 1 foot, areas of 1% annual chance stream flooding where the contributing drainage area is less than 1 square mile, or areas protected from the 1% annual chance flood by levees. No base flood elevations or depths are shown within this zone.

    Zone D – is the flood insurance risk zone that corresponds to unstudied areas where flood hazards are undetermined, but possible. Zone D designation may not be used in Flood Insurance Studies unless otherwise approved by the Regional Project Officer. It should be noted that the Mapping Partner is not required to perform a flood hazard factor analysis subsequent Zone A1-A30 or AE determination even though this information may currently be reflected on a community’s FIRM published in the non-map initiative format.

    Again, it’s always a good idea to talk with your lender and insurance agent about what this all means in regards to your insurance premium or ability to get a loan.
