Oriv�a. C�rnnn, MN Uear Mr, t�etz: At yaur �equest soil inspect�ons were made at the referer�ced site on June 10 and 11. The purpose of the inspections was to assess soii cundili��75 I�r tI�C single fa+nily residence planned for thi3 sitc. On June 90 the site had boon cxcavatcd to footin9 grado. �v,�o C�!I Rest proboC warp mad�with 2 hand auger, one at the fr�nt of the excavation, and one at the rear. Both test prabes showed 2 feet at low density, water saturated sand fiil above a sott, black, organic clay. A soft, gray clay loam materiai was found below the black arganic soil at both test probes. The site did not appear to be !avorable for spread footings on the sand without sail correction. On June 11 you arranged for your excavator to dig inspection trenches at the site The trenchss showed that srom 3 to 5 feet of excavation befo�nr footing level wil! be required tQ reach through the organic c�ay to a more acceptabfe clay loam soii, The gray clay loarn soil is what we believe to be the �I�s2�P��'�I��'�r'�f�drea Br�a'is not expected to have deeper, organic layers be3aw. The soil horiz�r� we found in the ins�ection pits, although better than the overlying organi� soils, is aiso sok to mcdiunt Stlff, and 1 r�coi�7�tiier�iiiecf ttidt you place a pad of clean, waslied, Guarse ayyi�g�te to distribute the footing loar�. Crushed, 1.:5 inch s�ze ilrnestone Is recommended. The aggr�gate p�d shoul� be piaced a feet wide under the footings and bucket tamp�d into the clay. We also re�emmended that you c�nb��uct ll��a �erir�neter f�unclation anly, eliminr�ting the center beering p�ds to m�nimize differentiai settlernent. This wi11 require construction af a structural floor. The perimeter footings should be strengihened with 3 numb�r 5 strands of steel r�inforcing. We understan�s thai you will construct a reir�forced, poured concrete foundation above tne rooc�ngs. �ven wftn tne soit irnp�nvements you snowa expecc some setncmont as the�i�y S��i a��te to tr� impcse� load. 11 is expected that the settfemer,t wi(I be even across the site and should not be detrimental to the structure if a we(I reinforced toundation system ;s constructed. With the com�pletion of the referenced soil corrections it is expected that a satisfactory foundation can be develap�d for the planned residence.
