A comprehensive surficial geologic mapping effort was undertaken to support the development of a series of relative flood hazard maps of the Ivanpah Valley area, Clark County, Nevada. The study area spans approximately 1030 km squared (398 miles squared) and is defined by all of three and part of one internally drained basins between Las Vegas and Primm, Nevada. The proximity of the study area to Las Vegas makes it a likely site of urban and suburban development in the near future, and it is currently being considered for the construction of a major airport facility. The geologic study focused on the delineation of surficial deposits of alluvial, aeolian, and playa sediments ranging in age from recent to late Miocene (approximately 5.6 million years old). Mapping emphasized the discrimination of active alluvial and playa surfaces from relict, inactive surfaces for the purpose of developing a relative flood hazard characterization to provide a baseline physical data set to guide floodplain management and more detailed studies related to hazard mitigation efforts in the area. Ideally, the maps will help planners understand the distribution of flood hazard conditions in the valley and direct mitigation efforts and engineering studies to areas with the highest potential for flooding. Study results indicate that 60% of the total study area (236 mi2) is composed of surficial geologic deposits. Within that subset, nearly 75% (175 miles squared) is subject to a relative flood hazard level deemed greater than "none", and nearly 53% of that area (125 mi2) is classified as having a hazard status high enough to represent a significant concern for floodplain management.

A series of 9 maps and a complete digital GIS dataset accompany this report. Report 53 online version, available free on the Web.

This project DVD contains all of the digital data used in developing the maps described in this report, including the following: geologic data geodatabase, field point and photo geodatabase, .mxd files used in ArcMap to display and print the maps, layer files (.lyr) that ensure the data are displayed the appropriate way, and .pdf files of each map (plates 1 to 9).
