Processing Steps

  1. Added Soil Layer to Carmel River Watershed map from SURGO file.
  2. Added the acreage for each soil type and displayed only the prevalent ones to reduce number of soil types from 160 to about 20.
  3. Reviewed which soils displayed and modified the list in order to insure those soils nearest the rivers and streams were shown.
  4. Created the legend for the soils layer.
  5. Modified the colors to better distinguish between soil types.
