S teps taken

1. Download SSURGO data for each of the 4 counties on the map (Monterey, Santa Cruz, San Benito, and Santa Clara) from one of the Useful Data Sources
2. Re-project each Layer into GCS North American Datum 1983
3. Create a shapefile representing the extent of the map (one way):
4. In the steps below, work with the soil type (soilmu_a) shapefiles
5. Clip each county's SSURGO data to the map rectangle just created:
   1. Analysis tools --> Extract --> Clip
      1. Repeat for each county layer
6. Merge the four clipped county MUSYM shapefiles into one shapefile:
   1. Data management tools --> General --> Merge
7. Add this clipped-merged shapefile
8. Use the "Muagget" text file to make a list of just the soil types and their correlating codes in the "MUSYM" column of the attribute table
9. Define symbology with a different color for each category of MUSYM (group categories by excluding slope percentage)
   1. Note, different counties appear to have used different codes for the same soil types, so there will be mis-matches at county boundaries
10. Do some kind of 'select' operation to create a shapefile or layer-file with the soil types that are inside the watershed boundary
11. Add a legend for this inside-watershed layer, and add an annotation noting that the legend does not contain soil types that are outside the watershed
