We are therefore requesting a permit be issued for the upgrade of the septic system to accommodate the three-bedroom home on the lot. The attached Site Plan and backup documentation identify the location and configuration of the existing and proposed septic system. The existing 1,000 Gallon Septic Tank will be pumped, crushed and backfilled and replaced with a new 1,000 Gallon Septic Tank. The existing absorption trench system will be left intact and tied to the new system with a flow diverter valve. Also identified on the plans are the locations of the existing well on this and adjacent lots and adjacent septic systems. No conflicts exist between the proposed septic system and the wells on this or adjacent lots. Protective radii are shown to the adjacent wells. Drainage arrows are shown indicating the current drainage patterns. The drainage patterns will be maintained after construction. A test hole was recently placed on the lot which indicated silty sand with a percolation rate of 2.5 minutes per inch. This test holes indicates the optimum location for the absorption area is at 10' below the ground. We have designed the new trench with an application rate of 1.2 gallons per date per square foot. We are proposing to place a 38' long by 5' wide trench with a 4' effective depth. The total depth of the system will be 14'. No groundwater was found in the test hole and none noted on previous test holes placed on this or the adjacent lot. We will continue to monitor the groundwater through construction of the new system. Any deviations from our assumptions will result in a redesign of the system and a change order request to the City. The ground surface on the lot slopes slightly to the southwest in the area of the new Lot 3, Block 3, May 4, 2010 Page Two Robin Hills No. 3 absorption trench. The trench will be placed parallel to the contours of the ground as much as possible and in conformance with design criteria. A minimum of 100' will be maintained between all components of the septic system and the proposed well and from any surface water in the area. If the system is constructed in accordance with our design the following statements apply: The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. 2. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. 4. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, n 4Ea Michael E. Anderson, P.E.

Box 1204 Anchorage, Alaska 99510 4040 "B" STREET, ANCHORAGE, ALASKA 99503 PHONE: 907-279-2581 August 8, 1975 W.O.# 17388 Re: Subsurface Soil Investigation for On-site Sewage Disposal Lot 3, Blk. 3, Robin Hills Subdivision No.3 Dear Mr. Willoughby: As per your instructions we conducted an exploratory effort on the above referenced lot to determine the suitability of the subsurface soils for placement of an on-site sewage disposal system. This exploration was conducted August 4, 1975, utilizing a B -50N Mobile Drill drill rig owned and operated by Denali Drilling Inc. The test hole was located on the lot as shown on the enclosed test hole location sketch - Figure 1. The test hole was logged and the soil. strata visually classified by Mr. O.M. Hatch, senior technician/staff geologist with Alaska Testlab. Table A is the log of this test hole, while sheets 1 through 3 contain standard explanatory information that may be helpful in interpreting the data and nomenclature of the test hole log. Visually, the only layer that appears conducive to absorb sewage effluent is the layer of silty sand encountered between 7 1/2 and 12 1/2 feet. This layer is enclosed, both above and below, by tight fine-grained soils. We decided, therefore, that an actual percolation test was required in the test hol.e. The test hole was filled with water to within three feet of the surface at 11:00 a.m. August 5, 1975. On returning on August 6, 1975, at 1:30 p.m., the water was down to 12.25 feet. At this time water was again placed in the hole to a depth of three feet and the drop in the waterlevel in the test hole recorded over approximately 20 -minute intervals until 5:10 p.m, that evening. During this time the percolation rate varied from 0.46 minutes per inch to 6.25 minutes per inch with an overall percolation rate of less than 1.5 minutes per inch. Mr. Richard J. Willoughby August 8, 1975 page two Utilizing the data presented in Table A "Absorption Area Requirements for Individual Residences" contained within "The Manual of Septic Tank Practice", published by the U.S. Dept. of Health, Education and Welfare, the required absorption area per bedroom for a residence located on this site, is 85 square feet. This is for the soils from the ground surface to 12 1/2 feet. It does not appear that the soils below 12 feet will percolate to any appreciable degree. It should be noted that on the date of exploration no water table was detected in the test hole. It should be note though, that the level of a water table generally fluctuates fairly broadly with climatic and seasonal changes, though we do not anticipate this being a problem at the site. We trust the foregoing is sufficient and complete to your immediate needs. Should questions arise, or if we can be of further service, please feel free to contact the writer. Very truly yours, ALASKA TES TLAB Melvin R. Nichols, CE Laboratory Supervisor MRN: mm.

Information, see Sheet 3 7) Other Information, see Sheets 4 thru 6 'Test Hole Lou — Description Guide The soil descriptions shown on the logs are the best estimate of the soil's characteristics at the time of field examination and as such do not achieve the precision of a laboratory testing procedure. If the log includes soils samples, those samples receive an independent textural classification io the laboratory to verify the field examination. The logs often include the following items: Depth Interval - usuallyshown to 0.1 foot, within that zone no significant change in soil type was observed through drill action, direct observation or sampling. Frost Classification - NFS, F1, F2, F3, F4, see "Soil Classification Chart" Texture of Soil - An engineering classification of the soils by particle size and proportion, see "Soil Classification Chart", note the proportions are approximate and modifications to the soil group due to stratification, inclusions and changes in properties are included. Moisture Content - this is a qualitative measure: dry_, no or little apparent surface moisture, damp, moisture forms portion of color, less than plastic limit, wet, no free water, often soft, if cohesive soil, saturated, free water may be squeezed out, if a freC draining soil; dilatent at natural moisture content, if a non -plastic silt or fine sand. (The moisture content is further defined by reference to PI, Ley, NP, M,Sor ddatency.) Density - refers to more -or -less non -cohesive soils, 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 the clay -silt 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 particle recovered by the split spoon is 1-3/8", Shelby tube 3", auger flights (minute -man) 2", Auger flights (A-50 hollow stein) 6"-S". Larger particles are described indirectly by action of the drilling and are referred to as cobbles, 3" to 8", or boulders 8"i-, Therefore when reviewing the gradation sheets, if any, the description on the hole log must be considered for an indication of larger particles. Unified Soil Classification - 'Phis is a two letter code. Sec 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. PI; natural moisture content believed to be less than plastic limit Pit; natural moisture content believed to be between plastic and liquid limits Lw+; natural moisture content believed to be greater than liquid limit NP; non -plastic, useful as a modifying description of some silty materials. Dil:nency -- is the ability of water to migrate to the surface of a smurtcd or nearly saturated soil sample when vibrated or jolted -- used as all aid to determine if a fine grained soil is a slightly or non -plastic silt or a volcanic ash. Rock flour -- finely ground soil that is not plastic but otherwise appears sine ar to a clayey silt. Organic Content -- usually described as Peat, PT, sometimes includes discrete particles such as wood, coal, etc. as a modifier to an inorganic 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 to describe very soft, semi -organic deposits usually occuring below a peat deposit. Amorphus peat - organic particles nearly or fully disintegrated. Fibrous Peat - organic particles more -or -less intact. Bottom of Testhole - includes last sample interval. Frost Line - seasonal frost depth as described by dfilling 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 fiozen soils - this is a special case related to permafrost studies. Free Water Level - The free water level noted during drilling. This is not necessarily the static eater table at the time of drilling or at other seasons. Static water table determination in other than very permeable soils requires observation wells or piezometer installations, used only in special cases, ]Slow/6" - The number of blows of a 140 weight free falling 30" to advance a 2" split spoon 6"; the number of blows for a 12" advance is, by definition, the standard penetration. M'Xo - natural moisture content of the soil sample, usually not performed on clean sands or gravels below the water table. TypeofSanhplc -- SP, refers to 2" split spoon .driven into the soil by 140 pound weight, a disturbed sample, S, thin wall tube, "Shelby" used to obtain undisturbed samples of fine grained soil, C, "grab" disturbed sample from auger flights or wall of trench, C, cut sarnple, undisturbed sample from wall of trench. Dry Strength -- a useful indicator of a soil's clayey fraction, N=None, L=Low, M=Medium, 11-Fligh Grou -- The samples are placed into apparently similar groups based on color and texture and are arbiumily assigned a group letter. Further disturbed tests including Arterberg Limits, grain size, moisture density relationship, etc. may be performed on the group and :ire .rssuuhed to reflect the general disuubed characteristics ul the soils assgtned to file group. This is an important Phase of' the soil :analysis and is used to standardize the various qualitative dewiminations and to reduce the number of quantitative tests necessary to describe the soil mass. 5 u y`o .5o�yo 3 >c�aA°O y 'c < u ¢ c - o uV U F' � ., 'a S 1pgwts Ir^p )o xn Hainn6>zzxo ampapsog SZ1 ot115- 9S•W3•09•WU 'AZT veyt cm.w n u�i v n r Biu WMS'dDW9 %S uryz szaq sopw.Opnzgd swollo) zr paprsrp ve spa p>urrll mro> b'' -r >""z o0Z •oN veyt sa0rms uo!uv)) s> � )o >Anua»d uo 8inpu>d>p vn> zu8 w°,) puss pue I>n:A)o sa8rru»nd awuu>t>O uonoynucpl Pp) z>pun uoni8 zr ruopv) >yt 9,d)nwPi sn a^sna nrs wrrA xp "o ]VLa va c ]E x c -.0 Ee`:v o- —° to E ., _ _ w p n i p C U W w U [v W o E- E °E ° U 5 V O E O U y -- _ -9 = o f c _ E o f o f 3 0 r:, a Z 00 v o „ ^oV E".: ., i E„' .. 1. qi c �E^ v° -E M° °Ep Za v< yE Nt S a w � (S>nll ° i2 n (s>ury °u m apuQ tun.rrrr ISJnr ou so n ,. e° si>nv8 yr>IO >Iyn>vddr) sauy 'p.,I) zpuez ue>,ID alga.uddel uml g a spun ........ zpueS Vyu.w E a` e OS ueyt zsal I P!^ I nI, Li ue t nu>zA V c (aqs an>P pap m m>IrnprL> sr pain rg (rm w F oyr'uopeay r•p Irnve ro;l) r's.(rp o put np, nwg piu6il s` nz roN ory 9 rdep pue ro uryz nA .Is umrrn) uryuallrnvs v v(snns) �- k,o csuoop.)py unp anly mrua yr)Ir.I onp anly q>en0 spur, w = Iv (>.t> Pry1” ur apiign ymvnl rsapnus vp uzoge U ans arms OOZ'°N >'IA) grrs >nms OUZ'nry n.yr nAnl >z^ aA>n OZ ..N unp 11 Igsjsrru p, )Ir'I urgr v.qy »Ilrars sl Inu¢w y. )py Up til vol, zpo, p umm..>zo;l sl�os p>.",s omd SOIL CLASSIFICATION CHART o SILTAIN �o 2 OR CLAY T 00 2 m 30% GRAVEL `ri 00 Q J O F` O /. f i (n - �9 oQ v��+� O % (p :s...•-„m.._..c. r es.�.-^-r.:�� .as:�,+rr..v�aA�wxc� :�^ .,. <�:as�„ O � CLAYEY CLAYEY ` CLAYEY / \ 7 / CLAYEY � o f OR\ OR- / OR SILTYSILTY OR A o SILTY , SILTY SAND I —7 GRAVEL GRAVELLY SAND SANDY GRAVEL „ixA'.ik�TlM”Y�'C-'FT.�:aL:2U`r�h1L1�.r�.._•,�••+:..�<�t32f:.-; \ f''C�d^JJB%E�}4Z-)=. r SST^ O \SAND/ \ GRAVELLY SAND SANDY GRAVEL GRAVEL 00 0 10 20 30 40 50 60 70 80 90 100 GRAVEL (+#4 SCREEN) '% BY WEIGHT NONFROST SUSCEPTIBLE SOILS ARE INORGANIC SOILS CONTAINING LESS THAN 3% FINER THAN 0.02 mm.
