Notes

1. The soil conditions are known only at the boring locations and are therefore accurate only at these points. The profile is based on interpolation or extrapolation between conditions observed at the boring locations and should be considered approximate.

2. Surface elevations are approximate.

3. No groundwater was encountered in Borings A-1-15 or A1-2-15 at time of drilling.

4. Only selected structures called out.

The soil conditions are known only at the boring locations and are therefore accurate only at these points. The profile is based on interpolation or extrapolation between conditions observed at the boring locations and should be considered approximate.
