Dear Fred: This letter is to provide a review of the design of your sub-surface septic tank sewage disposal system as shown on plans (one sheet) dated April 5, 1975 and certified by myself. The review is necessary because the Borough Department of Environmental Quality inspector stopped construction of the disposal system on Thu'rsday September 'Il, 1975, apparently because he felt that the water table Was not as that determined by Bore Hole No. 562007 (R & M Consultants, Inc.) dated March 27, 1975 and checked by reference to the monument bore hole across Lore Road from the construction site Project No. 4184030 dated January 5, !~_~ ................... ~ /f"" ~ We~ay-~P~er 10, 1975 ~-i~i~-e~ the construction si~e // when the seepage pit was excavated to approximately a six-foot depth an~ /found no ground water present in the excavation. The fact that your contrac- ~tor excavated an additional test pit at the construction site to the depth ~of twelve feet on Thursday September ll, 1975 without finding ground water ~, supports the data provided by the two previous bore holes. ~ ~ ...... I--~-l~v--e-~ e~o~ro~gh i-~sp~ctor could not make a clear d~st~nct~on between excessive rain water running into the 'top of the ditch and possible ground water. The following data on rainfall shows that this could be possible: Date Rainfall Monday September 8, 1975 0.47 inches Tuesday September 9, 1975 0.17 " Wednesday September 10, 1975 1.19 " Thursday September ll, 1975 0.97 " It should be noted that the average rainfall for the month of September in Anchorage is 2.37 inches and this year the rainfall for Septem- ber 1 through 15 is already 3.29 inches. Also between 9:00 AM Wednesday and 9:00 AM Thursday the rainfall was 1.74 inches, which set a 24-hour record for Anchorage; this was when the trench was open. Page Two - Mr. Wolfley I suggest that you review this data with the Borough in order that the building permit can be reissued and the project completed. I feel that the design data and resulting design used 'is correct and complete and con- forms to applicable code requirements. If necessary, I will be available to discuss the design with the Borough regulatory officials. Si ncerel y, da~es A. Crum, P.E. JAC:vz cc: File ~ i~, FAIIII]ANKS CONGU LT~kNTS, INC.

Dear Mr. Wolfley: We are submitting herewith the test boring results and our comments regarding soil conditions encountered at the subject site. This investigation was performed in accordance with your request of March 24, 1975, and those precedures outlined in a letter dated December 19, 1974 by Mr. Rolf Strickland of the Greater Anchorage Area Borough Department of Environmental Quality. A single test hole was put down within the Lot 1 area for thc purpose of defining gener~ ~ubsurface soil conditions for tho proposed sanitary syteh,, Excavation was accomplished with an auger type drilling rig a~d the test hole was extended to a total depth of 19 feet below ground surface, Two samples were recovered from the test hole and retained for grain size analysis. The res¥1ts of the sample analysis are enclosed, The final log prepared for the test hole has been included in Drawing A-01. Ground water was encountered in the test hole at a depth of 12 feet.
