Description: These boundaries were "roughly" digitized from a map at the full county scale (~ 1:150,000). They are not intended to be EXACT boundaries of historic floods from 1955 and 1958 but rather an approximation of those areas.The final product represented here are the areas in the historic flood map that are currently outside of a FEMA floodplain "A" area. Other modifications were made to the polygons represented on the historic map per Flood Management's suggestion. Contact Flood Management (Sam Sharideh) at 209-468-3605 for details.
