HYDROLOGY The water table was measured at ten (10) feet below grade in t1�e borings. The water table in this area fluctua�es with the tides and the river level. The imported fill appears to drain moderately v:ell. The underlying silts drain poorly. The underlying river sand is quite permeable. CUNCLUSIONS AND RFCUMMENDATIONS Due to the uncontrolled fill and the underlying soft recommend the use of piling to support the batch plant. tions for timber piliny are presented below. Higher other piling types are available if necessary. Driven Timber Piling soils, we Recommenda- loads using Driven timber piling would be well suited to the soil conditions at the site. Safe working loads of twenty (20) to twenty-five (25) tons could be achieved. We would anticipate below grade pile lengths of about forty-five (45) feet for twenty (20) ton piles and fi£ty (50) feet for twenty-five (25) ton piles. A minimum pile length of thirty-five (35) feet is recommended. Test piliny may be advisable before ordering production piling. A hammer rate�i at 15,000 ft. lbs. of ener.gy or more is recommended. The piling should be class B creosote treated, with the ends banded. All piles should be fresh headed before driving and any badly broom- ed ends should be cut off before driving is completed.
