P�ul, Minn�sota. 55117 Attention: Mr. Nordquist C�entlemen: Re: Soil Invegtiga.tion, Proposed Apartment Site, Roseville� Minnesota. Qn Deccmber 31, 196�r and January 2, 1965, we put down two soil test borings to aid in evaluating the soil conditions on a propos�d apartment site located on the east � and �rest sides of prQposed Dbllwood Stre�t b�tween County Road C2 and Josephine �treet in Rb$�vill�,' Minnesota. � The borings w�r� put down at the location� sh�wn on the attaehed sketeh. Surfaee elevations were referencad to ths top b� t�'1C fire hydrant loQat�d naar tha south.. west corncr of County Road C2 and I�ellwood Street, taken as 100.0' (an assumed el- evation). The logs of the borings� a tabulation of the laboratory test results, and a chart giving the method oi soil classification (U. S. Bureau of Soils) are attaQhed. The soil wag visually classified in accordance with the above method. Boring 2 was cased with 2�-�.neh pipe which was cleaned and advanced with a clean.- out tube. Boring 1 was put down uncas�sd, and r�as cleaned and advanced with a 2-3�8 inch pipe drill. �bil samples were taken with a 2-inch 0. D. split sampler, and� th�e blaws per foot (B P F) a� given along the right side of the logs�were recorded on this sampler driven by a 140 lb. weight falling 30 inbhes. The consistency of the cohesive soi]. was rated by the penetration of the sampl�r. The area is quite level, with portions having been filled� and the surface eleva- tions at the boring locations vary about 1'. It may be seen by the logs of the bor�.ngs that a 2' layer of fill was faund at the surface of boring 1. Layera of arganic silty clay loam w�re found at the surface or below �he fill and extend�d to depths of 3�° and 22' (both abou� elevation 89-�') in borings 1 and 2 respeot- ively. A layer of rather soft cla� was found at a depth of from 2�' to �' in bor- ing 2. The underlying soil�is predomin�.ntly granular in nature, except for lay- ers of rather so£t to medium clay loam found below depths of l6�' and 16' (eleva- tions 76.4' and ?5•9'' in borin�s 1 and 2 respectively. The granular soil va�ies in classific�tion from mostly sand to loarr�}r sand and sandy loam, �nd has a good to very good penetration resistance. AS A MUTUAL PROTECTION TO CLIBNTe.
