In our opinion, the seepage enr,ountered is the resuft of "recharge" generated by the infiltration of precipitation into the ground upgrade of this site. It has beer� our experience that groundwater and seepage levels should r•ot be considered static. Typically, fluctuations in the levels and rates of flow can, and often do, occur on a seasonal basis, after periods of heavy or sustained precipitation, or from surface flow from elsewhere on the property or its surroundings. 7his is of particular consequence or this prope�ty because of the sloping grade down roughly from southeast to northwest towards the top of the sites' westeni slope. Any potential earthwork contrac#or should be aware of the potentiai risk that groundwater seepage co�.;io r,e encountered at construction, particularly of the work is to be carried out in ti?e wetter winter months. The contractor should take appropriate measures irs his bid by including a contingency in his budget and schedule to accommodate the possible need to intercept, collsct, and dispose of groundwater seepage inflow under control during construction.
