S3178 X SEP £0 1973, .AUG INTRODUCTION Our preliminary geologic and soils investigation ~vas c~nducted on the Pohling property February 17th and 18th. The subject property consisting of approx- · imately 40 acres, is located along the east side of G Street between 64th Street and Dowling Road extension. Purpose of the investigation was to determine the extent .... and depth of organics and general characteristics of underlyil~~ soild preparatory sale or construction planning. · FIELD INVESTIGATION .. Surflcial geologic and soils conditions were exarnihed utilizing a truck-mounted B-61 Mobil Drill outfitted with 6 inch hollow flight auger. A tOtal of ten borings were completed on the tract with.spacing designed for Overall coverage; Boring depths ranged from 10 to 15 feet sufficient to penetrate the organic horizon and .sample underlying materials. Representat?o samples were taken of underlying soils on each boring as indicated by Figu=es 2 and 3. Two Standard Penetration tests were also taken to give an indt,~att,,n of soils bear',rog capacity. SITE CONDITIONS VEGETATION DRAINAGE TOPOGRAPHY Vegetation within the low lying Westerly portion of the tract consists primarily of '~ae typical spaghum moss formed tn'a swampy nq. uskeg environment. Stunted black spruce, characteristic of poor drainage, fringes the swamp area abutting' the small ridge to the east. The ridge or topographic high trending southeasterly through the property is heavily overgrown with larger. White spruce and'random birch. Aider forms a thick new growth along the.man-made drainage di~cli ami wcstc~'ly slope at Campbell Creek. Drainage of the swamp has been Somewhat enhance(~ by the afore- me~tioned man-made ditch. ' This transects the small ridge thus directing runoff toward,Campbell Creek rather than being entrapped in the depression surrounding Tine Lake. Nevertheless, drainage in the swamp area is pqor (vith standing water observed at some 3 1/2 feet in hole BH-3 and a high moisture content evidenced in the other swamp borings. Conversely, drainage on the ~m'a!l ridge and westerly slope toWard Campbell Creek is good to fair. . GENERAL GEOLOGY Geologic formations in this area are linked to s0me~.hat'complex P~e-Wisconsin ground morainal, glaciofluvial and glaciolac'u'strine deposition. The western portion of the front is masked by recent swamp deposits x:esulting from gradual organic filling of the Tine Lake depression." The coarse sandy gravel encountered in BH-3 at 'a depth .of 12 feet is indicative of ground morainal deposition whit:, prObably £(~rm~ an underlym, g blanket throughout the area. Overlying this is a cor,~ormable silt to ~layeY silt formed by , of silty sand to gravelly silty sanCk SUBSURFACE CONDITIONS Organic deposits along the property's ~es':e:-n m.arg{n range between 6 and 7 feet in depth. These are a product of decomposition of swamp or muskey vegetation generally dark brown and fibrous in appearance and with a high water content. The organic contact slopes gently upward to the e~st. In the wooded area the organics form a covering of 2 feet or less, are gray to lighter brown in color and have a siltsr admixture. ! I- l l l ] l- l The lake deposited sills and clayey silts occur dire. ctly beneath the swampy area. Boring No. 3 shows that in the northwest corner ti~ese have a ' vertical section of some 6 feet. Elsewhere the sequence whs not penetrat'ed.. However, it was encountered underlying the nose of the small ridge in the vicinity of BH-8 and BH-10 at a depth of 6 1/2 feet. This same deposit was als. o found to underlie a thin organic covering in the southeasterly corner.of the property. A Standard Penetration test of the silts taken on BH-8 indicates a soft consistency, or in other words, poor foundation conditions. The small (~blo'ng ridge consists ahnoSt uniformly of a'fine silty sand. Occasionally some small gravels were encountered as noted on the Log for BH-5. . " ' · Frost penetration at the time of our investigation was in the order of 1 1/2 to 1 3/4 feet. This ~hallow penetration is undoubtedly due to this years deep snow cover as. the silts, and to a lesser extent, the Sil'.ty sands along the ridge are frost-susceptible. CONCLUSIONS ANrD RECOMMENDATIONS On the basis of our investigation the "Pohling P~Zop~rty" is shown to exhibit variable subsurface conditions. Approximately 50 to 60 percent of the area consists.of swampy organic deposits (Qs) overlying lacustrine silts and clayey silts. The remainder consists -of the ridge crest silty sands (Qp) at least partially underlain b.y the lacustrine silts and near surface clayey silts (Qgl) which occur along the southeast ~orner of the property. The ground morainal sandy gravels found in'BH-3 prob~ly, exist at depth thiough the property forming a base for the other deposits. Based on a Standard Penetration test of the lower gro.und morainal material, we conclude that the bearing capacity will be in the or. der of 4000 pounds per square foot. However, the depth of this material may' make it impractical fox' foundation use with the exception of larger high rise structi~rSs or pil..e foundations, The silts and clayey silts are frost-susceptible and-otherwise unsuit- .able for foundation purposes. Dependent upon the intended uso these would require partial to complete removal with replacement of engineered fill. Otherwise pile foundations penetrating to the underlying gr~ivdls would be requix'ed. The silty sands along the ridge are adequate for spread footing construction with an estimated bearing capacity in the range of 3000 pounds per square foot. However, due to the silt content and general fros~ penetration in the Anchorage area we would recommend a minimum footirig.depth of'4, 0 to 4, 5 feet. Caution should also be used to the southwest where the silty sand thins out and is underlain by the lacustrine silts and clayey stirs. We would also recommend that at such time. as construction plans are formulated we be notified for assistance in foundation design location of structux.es and cost analysis.
