Date/Time of Soils Investigation: F', • Msi 13 2aj5 ( on �V Seeoot e
Summarv/Comments:
All proposed infiltration areas and existing, active utility lines located within the proposed basin/trench
must be marked and flagged. If these -areas -are -not -flagged -,-the Soils Scientist reserves the right to
decline to do the investigation. If the proposed infiltration system,will be located in an area of existing
payement.and there is no open area nearby-egdipment_capable of. breaking through the impervious
layer must be provided. The soils investigation does not take the place of a soils report prepared by
an appropriate. professional. The Soils Scientist will only verify the soil conditions that are reported in
the Soils Report, and make a determination as to the suitability of the site to meet the infiltration
...design requirements under NCAC 2H.1000, and assumes no. liability should the system fail.
