Summary

Description

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event,the 0.2-percent-annual-chance flood event, Floodway, and areas of minimal flood risk. The DFIRM Database is derived from the LOS ALAMOS County Flood Insurance Study (FIS), the City of Espanola FIS, and the Village of Chama FIS flood hazard analyses performed in support of the Flood Insurance Studies and FIRMs, and new mapping data, where available. The Flood Insurance Studies and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the Universal Transverse Mercator projection Zone 13 coordinate system referenced to the North American Datum of 1983. The specifications for the horizontal control of Base Map data files are consistent with those required for mapping at a scale of 1:6,000 and 1:12,000.
