MEMORANDUM April 26, 1983 Jerry Weaver, Planning Department Health and Environmental Protection S-6797 Cinerama Terrace Subdivision This department has reviewed the proposed subdivision, soils logs with the slope conditions and water table information and finds; prior to approval, all of Block 3 and Lots 1 through 8 Block 2 are subject to soils test, delineate 10,000 to 12,000 square feet less than 25% slope, monitoring of water table if soils logs so indicate. This data must be submitted to this department for review and approval of Phase I. Phase II - Lots 1 - 6 Block 1 and Lots 9 - 17 Block 2 will be tract until all of the proposed lots are tested for adequate soils, slope and water table. This data then will be reviewed for approval by this department prior to final sign off of the plat. John W.

Thomas Lipps ATC ENTERPRISES SRA Box 4084 Anchorage, Alaska 99502 January 25, 1983 SOILS FOR THE PROPOSED CINERAMA TERRACE SUBDIVISION Enclosed are the results of soil testing, performed by Alaska Environmental Control Services, Inc. (A.E.C.S.), on E 1/2, NE 1/4, Sec 1R3W, TllN and E 1/2, SE 1/4, Sec 1R3W, TllN BACKGROUND: This area lies in the upper ranges of the Little Rabbit Creek drainage. Little Rabbit Creek passes through the southwestern corner of the tract, while a tributary stream passes through the extreme northern end of the tract. A ridge dividing these drainages occupies the middle of the tract. Elevations range from 1295' to 1615'. Vegetation in the lower areas is primarly black spruce. Slightly higher and drier areas are dominated by white spruce with an occasional paper birch. The upper slopes are vegetated with hemlock on the northerly aspects and balsam poplar on southerly aspects. The extreme elevations, which are near treeline, have been cleared of vegetation to prove up homestead claims. Alder pioneered and still dominates these areas. Two smaller areas in the lower midslope have also been cleared and now have alder. The soils grade from loosely packed GM with angular cobbles at the top to organic soil underlain by ML with subrounded cobbles lower down. GP strata underlay the ML in some areas. DISCUSS ION: Tests were performed in conjunction with the requirements set forth in "Design Manual for On-Site Wastewater Treatment and Disposal Systems" published by the E.P.A. The testholes were dug by a D3B Catapillar crawler with a backhoe attachment betwen 1-11-83 and 1-18-83. The objective of our testing was to determine the soils suitability for on-site septic systems. The important soil characteristics are 1). soil depth (depth to bedrock); 2). depth to groundwater; and 3). soil permeability. Refer to the Appendix for individual testhole soil logs. SHALLOW SOIL: The results of our testing indicate that bedrock depths will not be a limitation in design and inst. alla.tio, n of on-site sy~stems. t200 UJesl 33r~1 Auenu¢, 5uii¢ [~ · Anc~oraq¢, AIasl(a 99503 · [907] 276-1361~, Only TH 35 uncovered bedrock at a depth of 10', which leaves ample area (1' to 4' depth) for a septic system. This testhole is circled in brown on the accompanying map. SOIL WATER: In general, water was encountered more frequently where the grade was less steep. Distinguishing between vadose water and groundwater was necessary. Distinction was made to determine the type of drainage necessary to amend the lot. We considered continuous water in mineral soil to the groundwater, while water encountered in the upper organic soil was vadose water. Groundwater was encountered in TH 1, 6, 13, 17, 18, 19, 20, and 25. These testholes are circled in orange. Although the groundwater was not close enough to the surface to present limitations in any of the testholes, the slow perc rates make in the upper strata most of these areas unacceptable for on-site systems. TH 17, 18, 19, and 20 are located in an area in which the groundwater may be drained and the now wet strata used for absorptioon areas. SOIL PERMEABILITY: Again greater slope and elevation often resulted in increased permeability. The exceptions to this are the lower, more level areas which are underlain by GP layers. UNACCEPTABLE AREAS: Surface water, probably from the recent snow melt, complicated our testing and we attributed some perc test failures to this factor. Please refer to TH 7, 12, and 14 and note the negative (increasing water depth) perc rate. Testholes 1, 2, 4, 5, 5, 6, 7, 12, 13, 14, 16, 17, 24 and 26 all had unacceptably slow perc rates. These testholes are circled in blue. We attribute gley soil (blue color) to iron in a reduced state. This condition occurs when oxygen cannot reach the iron (i.e. when the soils continually staturated). Testholes which were visually failed due to blue color are TH 23, 25, 26, 27, 28, 29, and 30. These are circled in red. In addition to perc tests that failed due to surface moisture, TH's 25 and 7 are inconclusive. We feel these areas may have acceptable absorption capacities. ACCEPTABLE AREAS: Passing perc tests were found in TH 2, 8, 9, 10, 12, 15, 21, 31, 32, 33, 34, 35, 36, and 37. These are marked in green. TH 38 wa8 not perced, however we anticipate an acceptable perc rate. CONCLUS IONS: Based on our testing we have divided the soils into 4 categories: 1) Areas with no Soils Limitation - plain area on map. 2) Areas with amendable soils limitations - vertical lines on map. 3) Areas with severe soil limitations - cross hatch on map. 4) Potentially acceptable areas with inconclusive testing - X's on map. With respect to proper functioning of on-site septic systems we recommend: Category #1 - No Limitations, Approved as Platted Category #2 - Required subsurface drainage - conditional approval as platted. Category #3 - Tract Category #4 - A. Approval as platted conditional to ~ further soil testing; or B.

John W. Lynn Environmental Specialist JWL/ljw 91 010 (4/76) ALASKA t;, ,LIIIROTIITleFITAL COFITROL $1 l JCl $, IFIC. Enqineerinq 6 ~nuironmentcd Studies June 16, 1983 Department of Health and Environmental Protection 825 L. Street Anchorage, Alaska 99503 Attn: John Lynn Dear Mr. Lynn: In June 1983, a series of test holes was dug for Mr. Tom Lipps in Cinerama Terrace Subdivision to determine whether or not there were soils suitable for on-site septic systems on each proposed lot. Percolation tests were run in all cases. Thirteen lots already had good test holes on them from work AECS had done previously, and as a result of the work done in June 1983, 24 more lots were found to have soils adequate for on-site septic systems. Thus 37 of the entire 42 lots in Cinerama Terrace Subdivision have suitable soils, most of which are silty sandy gravels with large percentages of gravel, particularly in Block 3, where the lots have exceptionaly good perc rates. Five lots were found to be unsuitable for on-site septic systems: Block 1 Lots 2 and 3, and Block 2 Lots 10, 11, and 12. All five lots have the same problem--the soils consist of peat, glay, and tan silt; none of which passed perc tests. Two separate soils logs and percolation tests were done on Block 1 Lot 4, so that if desired, the lot line bordering Lots 3 and 4 may be moved west to incorporate a good log and test on Lot 3. It is important to realize that Blocks 1 and 2 of this subdivision have water problems. Many lots have shallow water tables, as shown on the soils logs. Additionally, most lots bordering Little Rabbit Creek have surface water -- small streams are running over the peat. Extensive drainage is necessary, therefore, to get rid of this water--both to divert the small surface streams and to lower the water table, so that on-site septic systems may be installed safely. Tubes to monitor the water level were left in the test holes to ensure that the water table has been lowered before a septic system is installed. It is my recommendation, therefore, that the following be done: 1) That this subdivision be approved for final platting as it now exists, with the exceptions of Block 1 Lots 2 and 3 and Block 2 Lots 10, 11, and 12. These lots should either be tracted or combined into adjoining lots. 2) Extensive drainage ditches should be constructed to dry up those lots having water probelms. Mr. Lipps has indicated verbally that this is his intent. Sincerely, ~ Darcy Bev~ds Engineering Geologist Leroy.~.~.~Re~d Jr,, PhD~, P~.
