How does the FEMA mapping process work?
The city of West Sacramento is currently shown by the Federal Emergency Management Agency (FEMA) as being in a Zone X flood designation. Included in Zone X are areas protected by levees that can defend against water levels that have a one percent chance of happening in any given year, commonly referred to as a 100-year level of protection. FEMAs flood insurance rate maps show the level of flood protection in any given location and delineate where flood insurance would be required. As part of a nation-wide effort to update all flood insurance rate maps, FEMA is in the process of re-evaluating the level of protection provided by all existing flood protection systems in Yolo County and other areas.
