Moening ~ Re: Subsurface Soils Investigation for: a.t Roadway Design b. Percolation Testing Wooded Hollow Subdivision · Peters Creek, Alaska Our Job No. 83-054.01 ~- Dear. Harry, Pursuant to your request, we have completed a geotechnical subsurface soils investigation of the above referenced site. The purpose of this investigation was to determine the condition and nature of the subsurface soils~ percolation testing for on-site septic design, and to provide roadway foundation design recommendations. . The considerations and recommendations presented herein have been developed from observations made in the field, test hole drilling, percolation testing, and laboratory testing of selected representative samples. Subsurface soil conditions were evaluated at the site on March 30 and 31, 1983, by drilling e!ght (8.) test bo.rings at the approximate locations shown on :the attached Site Plan,.Plate 1. Two (2) test borings were drilled to assess subsurface soil conditions for the proposed roadway and six (6) test borings were drilled on Lots 2 through 7, respectively, for percolation testing. The roadway test borings and associated laboratory test results are ;)resented in Appendix A, Plates 2 through 7. The soil logs and percolation test results are presented in Appendix B. All of the test borings were advanced by means of a track mounted Mobile B-50 drill rig utilizing 6-inch O.D. solid flight auger. Disturbed samples were obtained from the auger return as drilling Mr~ Harry J. Moening Ju~e 16, 1983A'': Pag~ 2 progressed in each hole. The drilling was subcohtracted to Denali Drilling, Inc. of Anchorage, Alaska, .. While logging the test borings, observations were made concerning the presence of organics, moisture content, groundwater, drilling effort, and soil type and temperature. The soll was visually classified with respect to color and texture. Observations made concerning relative density were derived from the degree of difficulty of the drilling process. Groundwater was not encountered in:any of the boreholes while drilling with the exception of Borehole No. 3 where groundwater was encountered at 7.5 feet below existing ground surface. Seasonal "break-up" was occurring at tile time of drilling and it is believed that infiltration of surface water may have influenced groundwater levels. Groundwater levels were re-measured approximately one (1) week and again, approxi- mately eight (8) weeks after drilling. The re-measured water levels are indicated below: Water Levels ,(1]_ Borehole 3130/83 or 3/31/83 ~5/8__3 5/26/83 1 . None 2 None 8;2': None 3 '7.5' 6.5'~-- None (2),- '4 None .~ 6.5'~ None (2), 5 None, 8.5'~r 5,0' .... 6 None 13.2',~ 4.0' 7 None, 1.5~ 3.0' 8 None~ - (i) Measured from existing ground surface. (2) Borehole sluffed in to 6.0". PVC standpipe silted in at 6.0'~- Due to the high groundwater levels encountered, conventional trench type septic systems may not be feasible on Lots 31_through 7,~'. A shallow depth mound type system may have to be incorporated on these lots, Other portions of the lots may be more suitable for on-site septic systems. Surface runoff may be affecting the water levels within the boreholes. (--PeFEolation testing was performed in shallow boreholes drilled adjacent to the soils log boreholes on Lots 2, 3, and 5. Percolation tests were not performed on Lots 6 and 7 due to high groundwater levels. The GW.-GP material encountered on Lot 4 did not necessitate a perco- lation test. - ' Mr. Harry Moening June 16, 1983 Page 3 The existing granular soil beneath the surfacial organic material is expected to provide good support for the plannned roadway. No buried organics, debris, or soft fine-grained soils were encountered in the two (~)boreholes for the proposed roadway. All surfacial organic material should be removed from the roadway an~ the exposed surface should be recompacted to 95 percent of the maximum density as obtained by ASTM.test procedure D1557, Method D or the equivalent AASHTO specification. Backfill to bring the road to grade should consist of classified Type II granular fill. This fill should ~e compacted to the specification already stated. In any event, fill lift thicknesses should not exceed twelve (12) inches. Drainage ditches constructed adjacent to the roadway should not allow the ponding of water. In addition, ditch soils may necessitate the placement of an overlay filter blanket of granular soil to prevent subgrade soil erosion. Natural ditch granular so~ls however, are expected to be relatively erosion stable and accordingly ditch side slopes may be constructed to a maximum slope of 1.5 horizontal to 1.0 vertical. Seasonal frost heaving of this roadway is expected to be minimal provided positive drainage away from the roadway is maintained. While drilling it was noted that subgrade soil moisture contents were relatively !ow. ~ As has been our experience, conditions encountered during construction are sometimes different from those anticipated from the subsurface investigation. It is very important to insure that the planned work is executed in accordance with the preceeding recommendations and design specifications. In this regard, construction should be under the supervision of a competent engineer. Please do not hesitate to call if you require additional information or have any questions.
