Select each set by location
Export each out to its own shapefile

7. Converted each data layer to Raster

8. Give values of 0 & 1 for cell in each layer, making each layer Binary Code Conditional Statement

9. After Rasters were created for each polygon, Used Raster calculator
Command line and scripting

10. After Rasters were created for each polygon, Used Raster calculator
Geoprocessing Arc Toolbox Forum
Reclassing no data to 0

11. Once each Raster is given values of 0, or 1, Add all 8 layers together
