After determining the soil profile, soil properties for each stratum were calculated. For the cohesive layers (C and E), laboratory test results for unit weight, compression ratio, recompression ratio, pre-consolidated stress, and cohesion provided by TerraSense were averaged. For the granular layers (A,B,D,F), the unit weight, angle of friction, bearing capacity, and compression ratio were calculated by empirical graphs using the average SPT value for each individual layer.

After using Streamstats to determine the watershed area, a .SHP file was saved and uploaded to Web Soil Survey.  The watershed characteristics were transferred and the soil types were determined.  After using the soil types and the land use an overall CN was determined to be 76.

The team created a soil profile using the selected boring logs explained in the site plan update. The soil was separated into 6 strata. The top layer consisted of fill while the next layer was comprised of loose sand. The largest of the strata was the organic clay which was approximately 60 feet thick located at an elevation of about -10 feet. After the organic clay, a thin layer of sand was present followed by a stiff clay layer. The lowest layer explored was a dense sand layer approximately 95 feet deep.
