However, the department requests additional soils tests for Lots 9, 10, 12, 13. Note the tests for Lots 12, 13 must be in an area outside of the 200 foot well protected radii and a letter of app~ovalof the community well from the Department of Environmental Conservation, State of Alaska prior to final approval. Also, on-site sewer systems must be in an area less than 25 % slope.

Two test holes were performed, using a small backhoe. In both tests, no frozen ground was encountered at all, and the soil was beautiful clean gravel and coarse sand like elsewhere in the subdivision. These tests were spaced in a manner so as to give a representative idea of what the soil was like in the presumad permafrost zone (see map enclosed. ) Since no frozen ground was found at all, it appears that the test hole with permafrost was an unusual isolated pocket, and is not representative of any permafrost zone. The test hole that had permafrost in it differed fraql the others in that there was a layer of silty sand, with really fine sand, from 5 to 8 feet, which was frozen and hard like cement. This strata was not found in any other test hole. Apparently it is just a silty sand pocket that does not drain well and for some reason has not thawed out. This strata does not appear to be laterally continuous and thus does not appear to be a a serious problem.

HISTORY During the March 2, 1983 Platting Board hearing, Case S-6768 Eklutna East, which Subdivided four (4) lots into?ight (8) lots was approved. This preliminary plat is still pending. Since the approval of this plat, the Chugiak areawide zoning study has occurred. The result o~ this study is that thi~i~rticular site has been noted by-physical planning to be designated as one (1) dwelling unit to two (2) dwelling~ units an acre. The justification for this reclassification stems from the fact that the lot sizes of one (1) to two (2) dwelling unitsanacre is compatible to the surrounding land use pattern and the fact that these lots within McCabe Subdivision will be served by a co,~unitywater system (Dawn Water Company). The plat before the board, had been suk~itted for the June meeting, however this 15 lot plat was pulled in an effort to address staff's concerns regarding topography and vegetation. The 12 lot plat suk~itted for the July meeting satisfies staff's concerns and the petitioners goals. pETITIONERS 1-~i,~NT The petitioner for this plat is also the owner and manager of Dawn Water Company of which the proposed lots w~ll be serviced by. Increasing his service base will yield benefits such as delaying cost increases, providing a reliable water source to each proposed lot, minimize the potential for potable groundwater contamination and provide the opportunity to live in the growing co~unity of Peter's Creek. This part of the site is gently sloping to the southwest and the south half of the site is undUlating knolls. A bench (wooded slope) transects the site in a northeasterly direction'. SOILS One foot of peat over sandy gravel. unsorted sandy gravel. -- Rnolls consist o~ unconsolidated, SITE VEGwI'ATION In the northern part of the site is an open coniferous forest with White Spruce and Alaska Pape= Birch dominating and the remainder of the site is closed deciduous forest with a dense stand of Alaska paper birch dominating. ACCESS Access is gained to the site from the weSt and the New Glenn Highway by Chugiak Drive, from the south it is gained from Monron Drive which is only constructed to the southeast corner of the property. ALASKA June 27, 1984 Bob Drall Tryck, Nyman & Hayes . 740 I Street Anchorage, ~l~ka ' 99503 Dear Mr. Droll: on June: 20 & 22, 1984, ~]~.~ka Environmental Control Services, Inc. performed six soil te~[~ in the proposed McCabe subdi~on located along Ch~giak DIive in North Peter's Creek, The tests done were scattered over five of the twelve- propcsed lots ,~q a smal~ backhoe that could dig to roughly 12 feet_ The purpcse Was to determine whether' ar not soil which ~s permeable enough to support on-sLte septic systems was present in ~!f-~nt quantity to warrant subdividing. In ail the t~st b~ dug, excellent soil was found--clean grave]s and coarse sands~ which ail were visua]Iy ratsd between 85 and 150 square feet b~reem.
