We will need a new soil test and water monitoring on each lot. From old soils test information, it appears that Lot 7B will require additional testing to verify that there are three (3) potential disposal sites. The engineer should designate the appropriate reserved disposal area on all lots, based on soil information. The engineer needs to show existing sewer systems and wells within 200 feet of this proposed development and indicate what impact, if any, they will have on the proposed lots. We require information on water availability, and a plan for handling surface water flows, if any. We strongly recommend that the plat be returned to the engineer. Should this plat proceed, we wish to point out the applicant has failed to meet filing requirements in both Title 21 and Title 15 pertaining to subdivisions.

In- cluded with the report is a map showing test boring loca- tions, laboratory corrected test pit logs, grain size distri- bution curves, and standard explanatory information. As requested, several test pits were excavated on May 18, 1983 to determine the near surface soil and ground-water con- ditions for the design of street and underground utility sys- tems, The test pits were excavated using a Case 580D backhoe provided by Eastwind, Inc., of Anchorage. Eight test pits were excavated approximately every 300 feet along Lilac Court and Lilac Circle. One additional hole was excavated along the proposed storm drain 100 feet north of Huffman Road cen- terline. The test pits were located by cloth tape between existing 50 Foot survey stationing and offset to the left or right of centerline to avoid placing a hole beneath the road- way. lhe test pit elevations shown on the attached logs were estimated with reference to existing grade stakes along Lilac Court and Lilac Circle and are only approximate. When possi- ble the test pits were dug several Feet below the Finish grade elevation into the subgrade materials or below the pro- posed storm drain elevation. This depth varied between 5.5 and 10 feet along Lilac Court and between 7 and 11.5 feet in the two test pits on Lilac Circle, Representative samples of each major soil horizon were taken, sealed in plastic bags to retain natural moisture, and trans- ported to the laboratory where visual classifications, mois- ture contents and mechanical analyses performed on individual samples. The predominate soil type encountered below finish grade ele- vation consist of dense to very dense silty gravelly sand. Joe Cange June 2, 1983 Page 2 In test pits 4, 7, and 9, the sands are moderately Frost sus- ceptible, rated F2. Highly Frost susceptible (FJ) sands, with greater than 30 percent silt, were Found in lest Pits 3, 5; 6, and 8. The soils were Found to be more gravelly and less silty in Test Pit 1, classified as slightly Frost sus- ceptible (Fl) silty sandy gravel, lhe opposite is true in lest Pit 2 where the silt to gravel ratio is much higher re- sulting in a highly frost susceptible (F4) sandy silt. On ]est Pits 4~ 6, 7, 8, and 9, a 1 to 3 Foot layer of highly Frost susceptible (F4) sandy silt was Found at the surface overlying the sands. Most of the soils encountered are very close to the line which distinguishes a sand From a gravel or a sand From a silt. lhereFore, in some areas slight change in the sand content might result in considerable variation in textural or Frost classification. lhe hard silts and dense sands and gravels found througout the site are typical of sediments deposited directly by glaciers which covered most of the area in the past. lhese glacial deposits are characteristically poorly sorted mix- tures of materials ranging from boulders to clay. Locally the deposits may be better sorted and contain lenses of silt, sand or gravel. It is important to realize that significant variations in soil types should be expected over relatively short distances. No ground water was encountered in any of the test pits dur- ing the short time the holes were open. Ne hope this report is sufficient to meet your present needs.

Frost Classification - NFS, FI, F2, F3, F4, see "Soft Clauification Chart" Texture uf Soil An engineering classification of the soils by particle size and proportion, see "Soil Classification Chart", note the prop.rtions are approximate and rnodifications to the soll group due to stratification, inclusions and changus [11 properties are included. dr)', .,, ,ar little apparent surface moisture, damp. moisture forms portion of color, less than plastic limit, salutated, free water may be squeezed out, ifa free draining soil; dflatcnt ,~t natural moisture content, if a non-plastic silt or fine sand. [The moisture content is further defined by reference to PI, LW, NP, M% or dllatency.) l~nslty - refers lo more-or-less non-cohesive softs, such as sand gravel mixtures with or without a fine fraction, derived from drilling action and/or sample data: usually described as: very loose, loose, medium dense, very dense. General intent is to portray earthwork characteristics. Stiffness - refers to more-or.less cohesive soils and fine grained silts of ~sdl groups. Derived from drill action and/or sample data, Very soft, soft, stiff, very stiff and hard are commonly used terms. Particle size - The largest partic}e recovered by the split spoon is 1-3/8", Shelby tube Y', auger flights {minute-man) 2", Auger flights (B-50 hollow stem) 6"-8", Larger particles are described indirectly by action of the drilling and are referred to as cobbles, 3" to 8", or boulders 8"+. Therefore when reviewing the gradation sheets, if any, the description on the hole Jog must be canskieted for an'indication of larger particles, Unified Soft Clarification - This is a two letter code. See Unified Classification sheet for further definition, In some cases AASHO and/or FAA soil classifications may be shown as well as the unified. Atterberg Limits - useful for fine grained and other plastic soils. natural moistuxe content believed to be less than plastic limit P}+; natu.ral moisture content believed to be between plastic and liquid ~-miss L.~; natural moisture content believed to be greater than liquid limit N_.p.P; non-plastic, useful as a modifying description of some silty merit;ah. ,Dilatency - is the ability of water to migrate to the surface of a saturated or nearly saturated ~oft sample when vibrated or jolted - used as an aid to determine if a fine ~rained loft is s slighdy or non.plastic silt or a volcanic ash. Rock flour - finely ground soil that is not plastic but otherwise appears similar to a clayey silt, Organic Content - usually described as Peat, PT1 sometimes includes ~]'~crcte particles such as wood, coal, etc, as a modifier to an inorgamc soil. Quantity described as; trace, or an estimate of volume, or. in case of all organic, - as Peat. This may include tundra, muskeg and bog material. Muck - a modifier used tn describe very soft, semi.organic depos~ls us~-'~'i~y occur;ag below a peat deposit, Amor~huspeat- organic particles nearly or fully disintegrated. Fibrous Peat - organic particles more-or-less intact. Bottom of Testhole - includes last sample interval. Frost Linc - seasonal frost depth as described by drllliug action and/or samples at the time of drilling. Frozen Ground - other than frost line, described by samples, usually includes description of ice content, often will include modified Unified Classification for frozen softs - this is a special case related to permafrost studies, Free Water Level - The free water level noted during drilling. This i> not necessarily the static water table at the time of drilling or at other seasons. Static water table determination tn other than very permeable soils requh'es observation wells or piezometer installations, used onb' m special cases.

The EPA October 1980 "Falling Head Perco- lation lest" procedure was utilized For all tests. Since the percolation rates were moderate, successive half hour drops were observed. 1he test logs indicate initial and Final half houc water levels which a~e recorded as initial/Final depths to water on the attached test logs.
