ZONE AE Base flood elevations determined. ZONE AH Flood depths of 1 to 3 feet (usually areas of ponding); base flood elevations determined. ZONE AO Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); average depths determined. For areas of alluvial fan flood- ing, velocities also determined. ZONE AS9 To be protected from 100-year flood by Federal flood protection system under construction; no base elevations determined. ZONE V Coastal flood with velocity hazard (wave action); no base flood elevations deter- mined. ZONE VE Coastal flood with velocity hazard (wave action); base flood elevations determined. FLOODWAY AREAS IN ZONE AE OTHER FLOOD AREAS ZONE X Areas of SOO-year flood; areas of lOa-year flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 100- year flood_ OTHER AREAS ZONE X Areas determined to be outside 500- year flood plain. ZONE D Areas in which flood hazards are undetermined.

Reference Mark *Referenced to the National Geodetic Vertical Datum of 1929 NOTES This map is for use in administering the National Flood Insurance Program; it does not necessarily identify all areas subject to flooding, particularly from local drainage sources of small size, or all planimetric features outside Special Flood Hazard Areas. Areas of special flood hazard (lOO-year flood) include Zones A, AI-30, AE, AH, AO, A99, V, VI-30 AND VE. Certain areas not in Special Flood Hazard Areas may be protected by flood control structures. Boundaries of the floodways were computed at cross sections and interpolated between cross sections. The floodways were based on hydraulic considerations with regard to requirements of the Federal Emergency Management Agency. Floodway widths in some areas may be too narrow to show to scale. Floodway widths are provided in the Flood Insurance Study Report. Coastal base flood elevations apply only landward of the shoreline. Elevations reference marks are described in the Flood I nsurance Study Report. l!) f'o o o ....J W Z <( 0- (/) z <5 J For adjoining map panels see sepafately printed Map Index MAP REPOSITORY Office of Rio Blanco Planning Department, County Court House, 6th Main Street Meeker, Colorado 81641 (Maps available for reference only, not for distribution.)
