Date/Time of Soils Investigation A
Summary/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
pavement and there is no open area nearby equipment 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
