Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.
This ArcView shapefile shows the locations, as polygons, of all identified flood-plain sand and gravel mine sites with active, terminated, and no-permit status across Washington State. The Washington State Department of Natural Resources, Division of Geology and Earth Resources administers the Surface Mine Reclamation Act (RCW 78.440, a reclamation law that requires a permit for each mine that: (1) results in more than 3 acres of surface disturbance, or (2) has a high wall that is both higher than 30 feet and steeper than 45° (Chapter 78.44 Revised Code of Washington [RCW]; Chapter 332-18 Washington Administrative Code [WAC]).
Geographic representations of identified flood-plain sand and gravel mine sites within Washington State by individually digitized polygons.
October 2001
These polygons were digitized "free hand" utilizing 1:12,000-scale digital orthophotos and 1:24,000-scale digital topographic maps (Digital Raster Graphics) from the Washington State Department of Natural Resources (DNR) corporate database. The digital orthophotos have an 8-foot pixel resolution and a horizontal accuracy of ±20 feet. The spatial location of surface mine locations was further augmented by utilizing information from the DNR Asset Performance System (APS) and in DNR surface mine permit files.

LRB
Shortest straight-line distance from surface mine polygon to river channel as measured in ArcView, given in feet. Sites listed as "0" feet from river were found to have active water flow through the mine site.
KWW
Total calculated mined volume of mine site in cubic yards. Value is obtained by multiplying surface area of mine and depth of mine (this method assumes that the mine walls and floor are vertical and flat, respectively). Values are rounded to the nearest 1,000 cubic yards. ND = no data available
