Transmitted herein are the resul~o of test borings placed in the project property at the specified locations and depths. The data is organized in this report as follows: Test Hole Location Jketch Figure 1 Test Hole Logs Sheet I 'ko 2 Standard Explanatory Data Sheet 6 ~o ~{ The test hol~s were drilled by Denali Drilling, Inc., super- vision, testing and report by Alaska Test!ab. The test holes were placed by means of a Hodwell !~ounted Mobile B-50 drill fitted with solid flight auger. Grab .samples were taken from the cuttings and from the auger bit as needed. The test holes were placed on the 12th of April ~975, super- vised, logged, and sampled by ~-[r. Bruce D. Ken:~orhhy, 'techni- cian of our staff. The soils found in this study are predominantly borderline with regard to frost susceptibility. Tile soils at depth were silt-sand-gravel mixtures GP/G~4, possibly unsorted glacial till overlain by windblown sand-silt mixtures. No free water was observed in either test hole. 'Che Grea'her Anchorage Area Boroug'h has established the amount of. seepage area per bedroom required for a particular seepage pit based on the unified classification of the soil. ~'~e understand this criteria to be as follows: Unified Soils Classification Seepage Area Required GW-GP 85 ft2/bedroom GM 225 ft2/bedroom SW 125 ft~/bedroom SP 150 ft~/bedroom SM 250 ft2/bedroOm ML 275 ft2/bedroom CL-CH 350 ft2/bedroom Soils with a seepage area valuel of greater than 250 ft2/bedroom are generally considered not sufficiently permeable to accept effluent. Additionally, the bottom of any seepage pit is required to be 4 feet above the free water level. The unified soils classification of each soil type en- countered at the time of exploration are contained on the test hole logs, should proportioning a specific seepage pit .in the area defined by a specific test hole.~be required. If there should be any questions on the above please contact our office. ~ Very truly yours, ALASKA TESTLAB B soe, Supervisor KWB: rb Enclosures #2 ~ ! 1 I Test Hole ~il WO # 1V285 Depth in Feet From To 0.0' - 2.0' 2.0' - 6.0' 6.0I -- 16.0' Elevation: Existing Ground Soil Description F-4, Sandy Silt, ~,~IJ, reddish brown, v;et, some fine organic material, soft.

If the log includes soils samples, tho=e ~:nples receive an independent textural classification in thc labora=ory to verify :he field examination. '/'he logs often include the following item~:. D~:h Interval -- usually shown 'to 0.l foot, within that zone no s!&ni,qcant change tn -.oil type was observed through drill action, direct observation or satnpling. Frost Classi~cation -- NFS, Fl, F2, F3, F4, see *'Soil Clattification · Texttu:e of Soil -- An engineering classification of the soils by pa:tide ;:se and proportion, see *'Soft Classification Chart", note proportions ~e approximate and modifications to the soil group dee to $'.rati:'ica:.ion, inclusions and change, in properties are included. :.5ois:ure Content -- this i$ a qualitative measure: dr.__?-, no or lilt!= .tpparent star face mol*lure, damp, moisture forms, portion of color, less than plastic limit, wet, no free x~,ater, often soft. if cohesiYe soil, s4turated, free water may be squeezed out, ifa free draining soil: dda=en: at natural moisture content, if a non-plastic silt or fine ~n'd. {The moisture con;.ent ix further definedby re~ecence to PI, LW, N?, r,l?a or al!latency.} Density -- refers to more-or-less ?~on.cohesive soils, such as sand gravel ~7~X'-tt-7,r'~s with or without a fine fractiou, derived from drilling actiou and/or ~mple data; usually described as: very loose, loose, medium dense, very dense. General intent is to portray earthwork c?:a:acterisScs. S'.iffne~s -- refers to more-or-less cohesive soils and fine grained silts of t,t~e clay-silt groups. Derived from drill action and/or sample data. Very .~oft, soft, stiff, very stiff and hard are commouly used terms. Particle size - The largest particle recovered by the split spoon is 1-318", Shelby tube 3", au'get flights {minute-man} 2", Auger flights {B-.S0 hollow stem} 6"-S". Larger particles are described indirectly by · a:tion of the drilling and are referred to as cobbles. 3" to 8", or .. boulders 8"+. Therefore when reviex*,ing the gradation sheets, if any, the description on the hole log taus= be considered for an indication of · larger particles.
