Data Source History:
Joan Curtis (Office of Planning and Building) supplied Jake Schweitzer, In Situ Mapping, with paper Flood Insurance maps of the City of Oakland. Jake scanned or manually captured the boundaries of the flood plains on these maps and assigned them attributes (A or B) as labeled on the source maps.
Joan Curtis reports that the original maps were surveyed at too small a scale to be useful beyond very general reference purposes.
