Northern Lights Blvd. Anchorage, Alaska ATTENTION: Mr. John Cannon JUN I973 Re: Soils and Foundation Investigation for 2 Five-Acre Tracts in Section 22, Township 12N, Range 3W, Seward Meridian Gentlemen: As you requested, we have conducted and completed a soils and founda- tion investigation of the above-referenced property. Our investigation was conducted in order to determine the geological and soils conditions of the site with particular attention to soil percolation conditions. The field investigation consisted of a geologic reconnaissance and the drilling and sampling of 3 test' borings. Utilizing a track-mounted Mobile Drill B-61 and 6-inch diameter solid-flight auger, the test borings were drilled and sampled and the soils were examined and classified according to the Unified Soils Classification System. The site is located on morainal deposits composed primarily of brown sandy, pebbly silts and silty, sandy gravels. These glacial soils are typical of those found in ground morainal and lateral morainal deposits and the general topography and vegetation indicates that the overall geologic and soils conditions of the :site are fairly consistent. The site is reasonably well -drained as indicated 2227SPENARD ROAD · ANCHORAGE, ALASKA 99503 - Telephone: 277-7601 277-7602 F, ~M. Lindsey & Associa,.s 7 May 1973 Page 2 by the topography which slopes gently from the southeast toward the north and northwest. Most of the vegetative cover consists of fairly large spruce trees with scattered birch trees. The test borings were drilled to a depth of 15 feet and the soils were classified as glacial till consisting of sandy silts and silty, sandy gravels. According to the Unified Soils Classification System, the soils encountered on the site are classified as follows: 1. Organic material and organic soils (Pt). 2. Silts and sandy, pebbly silts (ML-SM). 3. Silts (ML). 4. Silty, sandy gravels (GP-GM). 5. Silty gravels (GM). Groundwater was not encountered in any of the test borings and the soils are consistent of low moisture content. Based on our investigation, we are submitting the following conclusions and recommendations: 1. Sewage disposal on the site is feasible and can be based on seepage rates of 150 to 225 square feet per bedroom, or an average of 175 square feet. The soil stratum consist primarily of silty, sandy gravels which are found at shallow depths and are fairly consistent over the entire site. 2. Planning for water supply to be developed from water wells can be done on the basis of the previous history of water development for the general area. The morainal deposits are capable of yielding water from sand and gravel strata, if F. M. Lindsey ex Associat,,-a :Page 3 7May 1973 present in these types of deposits, but the overall silty nature of the majority of these soils is generally not conducive for large yields. 3. The general soils and foundation conditions are adequate for sub- division development providing that all footings are placed below the seasonal frost penetration depth of 4.5 feet below the surface. The silty soils encountered on the site are frost-susceptible and all footings should be placed below seasonal frost penetration depth to prevent frost heaving. It has been a pleasure conducting this study for your office. Please call us if you have any questions or comments about the report.

Beck; On September 9, 1974 one of our Inspectors found that the Inlet-outlet markings were reversed on two septtc tanks betng Installed In Bomalls ~Subdtvtston. Further discussions with Hr. Jones and subsequent Inspection of tanks In your yard on Arctlc Boulev&rcl confirmed the fact that the tanks were mislabeled. I understand that there lsa posslbfltty that between 15 and 20 of these tanks may have been installed. If Installed In the backward posttton a raptd faflure of the dratn fteld or leach pft could be expected from the car~y-over of soltds. Therefore, one should proceed wfth haste to fdenttfy and correctly ~elnstall the tanks to prevent further damage to the seepage systems. ' Wtthin aftve day pertod,! would appreciate knowtng your plan of action to identtfy and correctly reinstall those systems. !f thts '~epartmen~ can be of assistance, please call me at 274-4561.
