Geometry Type: esriGeometryPolygon

Description: The DPS floodplain map shows floodplains and other relevant drainage-related information over a Geographic Information System (GIS) map. The goal of this map is to provide engineers, planners, and property owners with useful information regarding floodplains and drainage. The map collates federal and local floodplain maps in a single resource to enhance public awareness and understanding of flood-prone areas, potential flood risks, and associated hazards within a specific region. There may be situations where:FEMA says a property is outside the SFHA, but DPS still regulates work there because of: local studies, buffers, drainage criteria, or updated hydrology. In these cases, DPS floodplains supersede FEMA floodplains.
