Cuts and fills of up to about 81eet had been proposed tor the development, but deaper fills were needed in some swale areas where sign'�'icant depths of organic sdis were removed. All ot the fill used was on•site soil generally from tho knoll ar�a Thic soil moatfy conaiata of weathered end unwsathered Glacial Till,which is comprised of grnvel, sitt, e,id sand. Some sand wau dao encountored. The stte sofl Is vory similar to the soil on other developma�t sites we have worked on In the near vioinity. Fdlowing the sVipping of tha organic, s�cial soil,the 811 was placed In approximately 1-(oot lilts antl oompacted with a v�bratory roller. Because the development pien for this pro(ect was preliminary, our primary wcrk at the site was to ensure mat the bullding pad are2� was adequately stripped, and that the f�l was o0mpdctad to at least 95 percent of the labotatory maxlmum dry dansiry in generd accordenoe wiih qSTM 0.1bb7 (Modifted P�octor), This compacUon rate was generally tested to ebout 10 }eet outside the proposed building pad, although the compactlon eNat extended about 15 feet east of 2he bulidfng pad to near the southeastem aomer(�ear Stake �371� baeausc a depth o! appraalmataly 1S teet of fill was naeded. We parformed numerous denslry tosts in acoordanoo with ASTM p-Y922(Nudeu(iauge Method) between August is and September 1, 1995 on the compaeted 611 during our daily, periodie visits. Compacdon oi at least es percent was found in our test loeations. It appeers that the site fill was adequately compactad in the proposed bulld(ng pad azea Currently, the bu7ding pad is at its propased ftnel grade, and a large stoc{q�iio of the organic soils removed from the pad aroa ia an'tho tko's saetem edge. ' Just outside the soulheastern comer of building pud, near Stake #3717, logs and a farge amount of o�d fill were encountarad in what appaarad to Iw a large ewde. The dd fill and logs in and near the buiiding pad were removed, hut these materials were lefl in place outside the buifding pad, where we assume a potantial pavement area could be. Although the exini�g soils in lhis po�antial pavement area oould possibly be su;tabla for pavamont support, the area should be more closely evaluated by our personnel once a finzl design plan is availabla and(inal oarthworlc fs being perfartned. � CEOTEGHNI AL D sirN w�cnM�u�NnarinNa �onvonSional FoundetYone The proposed structure can be suppated on conventional conUnuous and spread footings beerinp on the c�mpatont, nativo coilc or the eompacted fill. We recomme�d thaz continuous and indfvidual spread footings have minimum widths of 24 and 30 inches, respeetively.
