Flood Data: Russian River Basin, California, (Q3) 1996

Description:

This polygon shapefile represents the portion of the Federal Emergenecy Management Q3 Flood Data Management maps within the Russian River basin region of California. Flood Data are derived from the 1:24000 Flood Insurance Rate Maps (FIRMS) published by FEMA. This layer can be used for watershed analysis and planning in the Russian River region of California. The FIRM is the basis for floodplain management, mitigation, and insurance activities for the National Flood Insurance Program (NFIP).
Insurance applications include enforcement of the mandatory purchase requirement of the Flood Disaster Protection Act Specifications for the digitizing
of FIRMs to create the Q3 Flood Data are consistent with those
requirements for mapping at a scale of 1:24000. Horizontal control of
Q3 Flood Data was established using USGS quadrangle maps at 1:24000 or
other standard scales. Users should assess the horizontal positional
sources and the requirements of their application. With increased
frequency, large-scale spatial data sets are becoming widely available
for computer-based geographic information systems. Q3 Flood Data may be
used in combination with other digital spatial data, however, users
should be aware that scalar enlargements do not enhance the relative
accuracy of the Q3 Flood Data (i.e. 1:24000). This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.
