The Floodplain Mapping/Redelineation study deliverables depict and quantify the flood risks for the study area. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).

The flight and images produced under this task order have been supplied to Nez Perce County for use in the development of the geographic information system (GIS) for the county of Nez Perce, Idaho and Lewis Clark Valley area. Digital orthophotos are aerial images corrected for displacement caused by relief in the Earth's surface, camera/sensor lens distortion and tilting of the sensor at the time of image acquisition. Additionally, orthophotos are assigned a uniform scale, which allows an end-user the ability to derive accurate measurements from the imagery. Orthophotos can be used as an accurate record of landscape conditions at the time of the corresponding aerial imagery. As such, the digital orthophotos are used in a variety of applications, such as environmental monitoring, facility engineering/maintenance, city/county planning, property line review, etc. The digital orthophoto can be used alone or as a raster base map for corresponding vector line mapping. These data are horizontally referenced to the North American Datum of 1983 (NAD83) 2011, Idaho: State Plane Idaho West Zone (Idaho portions) and vertically referenced to the North American Vertical Datum of NAVD 1988. Survey Feet have been adjusted to ground for the Idaho portions. Units are in U.S. Foot.Individual image tiles can be downloaded using the Idaho Aerial Imagery Explorer.These data can be bulk downloaded from a web accessible folder.Users should be aware that temporal changes may have occurred since these data were collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of the limitations of these data as described in the lineage or elsewhere.

Public Land Survey Sections represent the boundaries of land survey features called sections, which are generally one mile by one mile rectangles and are part of Public Lands Survey System Grid. Normally, 36 sections make up a township. The section is widely used as a reference when describing the location of property and deed descriptions.
