Preferred Risk Flood Insurance and those that come under the SFHA i.e. The FEMA’s Flood Insurance Rate Maps for Sacramento indicates the areas of the Sacramento city which qualify for PRP i.e. These maps are usually obtained by the satellite or aerial images and therefore are more accurate and reliable for future risk management. The historical Flood maps are important for the management of floodplain and also keeping the track of ratings of flood insurance. Since the FIRMs are updating, historic flood maps are stored as the digital FIRM images previously effective and now been superseded by the new ones. There is no detailed analysis available on the possible associated hazards and therefore the flood insurance for these areas also correspond to the accompanying uncertainties. These areas are marked by the zone D and indicate the possible risks of the flood that are not yet determined. The communities participating in the National Flood Insurance Program in these areas need to have mandatory flood insurance for every individual. These areas are marked with an annual 1% flooding chance but with additional dangers and hazards associated with the storm waves. The coastal areas that are considered high risk are represented by the zones V, VE, V1-30. With certain differences in average depth and evaluations of the base flood, these areas represent the annual 1% flooding chance.Īccording to the National Flood Insurance Program, all the communities falling under the high-risk zones need to have mandatory flood insurance applying to every zone mentioned. The areas which are marked as high risk are shown on the FIRM with zones A, AE, A1-30, AH, AO, AR, and A99. In moderate and low-risk areas, the flood insurance is provided to owners of the properties and renters in the given areas. It also includes the areas with unshaded C and X which are typically the areas beyond the 500 years level. These flooding areas are shallows with the average depth being less than one foot. If you look at the FIRM, you can identify these zones with shaded B and X areas which comes under the flood limits of 100 and 500 years. The following zones can be identified based on the classifications in the FEMA flood maps The base flood which is termed as 1% flood chance annually is considered heavily risky. The classification system follows the basic categories of 1% flood chance annually, 0.2% flood chance annually and the areas with minimal risk of flood. The FIRM by FEMA classifies various regions based on the risk of flooding in a particular area. Basically, the databases of NHFL comprises of digital formats of Flood Insurance Rate Maps (DFIRM) which are available in the published form from FEMA. This database is, however, acting as a subset for the study and utility of insurance in the regions called Flood Insurance Studies (FIS). The data on the FIRM can be detected in a format that supports the digital technologies and helps the institutions for disaster management through “National Flood Hazard Layer” (NFHL). The data gathered through FIRM is utilized for the floodplain administration, mitigation and further for activities of insurance for the umbrella program of NPIF (“National Flood Insurance Program”). which explicitly explains areas of hazards and risk zones for floods called Flood Insurance Rate Map commonly termed as FIRM. “Federal Emergency Management Agency” (FEMA) has chalked out various official maps of the communities within the U.S. If you have additional questions feel free to visit our flood insurance page or call in and speak to one of our agents.įlood mapping is done to observe the flooded region which can include following types of mapping The information gained through flood mapping is vital for rescue operations and assessment of flood hazards associated with a particular area.

Similar to other areas, Sacramento flood map is available at their site but in order to comprehend and gain detailed flood information from the map, you need to understand the few terms which would help you use the map effectively. Flood mapping (including flood insurance rate map, flood hazard map and historic flood map) is the procedure through which areas exposed to the risk of floods are chalked out on a map.įlood maps in U.S.A are maintained and updated by the “Federal Emergency Management Agency” (FEMA).
