VIEW �7 _ i This lefter zs wzitten pursuant to your tequest for a site investigation o� ' the three subject Lots regarding the bearing capacity of the soils: - On the date of this letter, I performed penetzometer tests at 1-foot (depth) intervals to a total depth of eight feet in £our sepazate test holes as shovn on the ac:�mpanying plat tnap, The test holes uer.e dug by a standa.rd size constr.uction backnoe. The area in question is apparently a fzll area. The fill has been in pl�ce for zeportedly approximately thirty years (per Bert Cronin il/92I , All four holes demonstzated approximately the same scil psofile, which would indicate that the fill is uniforta and homogeneous thtougqout thP area of the thzee lots in question. The soil profi2e showed a one to txo foot iayer. of dark brown I topsoi.l (sandy loam), and below that, a qrey loamy sand, with cobbles and pebbles. Due to the larqely granular natuze of the soil, I xould consider it�s composition very qood fcr suppozti.nq typica3 house loads. The re5ults of the penettometer suzvey aze as follows; � ' 6' � Typical allowable bearing pressure of approximately 2,000 - 2,500 pounds per square fbot {psf) . 6� ' 8' � Typical allovable bearing pressure of approximately 1,000 - 1 SUO psf. � . Continuous footinqs for standard two stozy constzuction should not exett lonq term Loads of greater than 1,500 psf on the soi2s immediately beneath the footings, as long as the `ootings are at least 16-inches cride at their base. It is my understanding that Crohin Homes, Inc. uses 16" wide footings as ' standard practice. Due tn the distribntion of the applied load over a larqe area With xncreasinq soil depth, the pressure on the soil six feet or qreatec below the footings rrill be £ar less than 1,000 psf. Regarding anticiQated settlement, the upper six feet oE soil should not settle any appzeciable amount, it appears to have been previously pzoper�y compacted. The los+er soil horizons may experience a very small amount of settlement due of the relatavelylsaallhloadeinczeasen�uniformitytof thebmatezialenta] because 1
