The fre. �ruining material should extend up the wall to I foot below the finished surface. The top foot of soil should consist of impermeable soil placed over plastic sheeting or building paper to minimize surface water or fines migration into the footing drain. Footing drains should discharge into tightlines leading to an appropriate collection and discharge point with convenient cleanouts to prolong the useful life of the drains. Roo� drains should r�ot be connected to wall or footing drains. USE OF THIS REPORT This report is the property of Nelson Geotechnical Associates, Inc. and has heen provided to Mr. Don Schwab and his agents, for use in the planning and design of this projec: on this site only. The scope of our work does not include services related to conswction safety precautions and our recommendations are not intended to direct the contractors' methods, techniques, sequences, or procedures, except as specifically described in our report for consideration in design. There are possible variations in subsurface conditions behveen the explorations and also with time. Our report, conclusions, and interpretations should not be construed as a wa:ranty of subsurface conditions. A contingency for unanticipated conditions should be included in the budget and schedule. NGA should be retained to provide monitoring and consultation serv�ces during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether o: not earthwork and foundation installation activities comply with conhact plans and s� ecifications All people who own or occupy homes on hillsides should realize that landslide movements are always a possibility, although the likelihood is low that such an event will actually occur. The hillside shoufd remain stable during normal environmental conditions; however, inherent t� steep slope areas is the risk of movement due to extreme environmental conditions such as severe earthquakes and storms. liecause of the existing sloping conditions, the area should be periodically inspected by the landowner, especially after a winter storm. If distress is evident, a geotechnical engineer should be contacted for advice on remedial/ preve�tative measures. The probability that landsliding will occur is substantially reduced by the proper maintenance of NELSON GEOTECHN/CAL ASSOC/ATES, /NC. �
