MUNICIPALITY OF ANCHORAGE DEPT. OF HEAL1H & ENVIRONMENTAL P~OI'ECTION JUL Lots 1, 2, 3 & 4, Tr. BI, StorcW Subdivision, Add~tiot~ #2, SeuLiu, 35, .....~x~m, R3W, S.M. C~se: S-72(5 Thank you for your time yesterday, Lucille and Mike Johnson, ~wners of the above Subdivision, have been hearing confusing reports concerning the soils and parc. tests. This letter 'is to summarize the converatie~ you and I had on that subject. i'i~e status of soils tests and percolation tests on eaci~ lot is as follows: Lot i ~ Test Hole No. 1-and Parc, Hole No. 2 After looking at the soils log and percolation test results, stated that a permit could be issued for this loto ~-,.~.~ ~ "- Parc. Hole No. 7 Lhis percolation soils log is required. grou~ld we, tar. test is acceptab')e, but a deep hole and Test Hole No. 2 on this lot had Lot 3 ;~fter reviewing the soils log and percolation test result~ .For Test Hole No. 4 and Test Hole ,No. 6, you stated that a permit coul,i be given for either area c.n this lot. 'Test Hole No. 3 had high grot;nd water. Lot ~ A deep hole next to parc, hole no, 8 showed ground water at 5 feet. We will drill another hole nearer to Rabbit Creek Road, lookin~ for a lower ground water table. A curtain drain will remain another option if the water table must be lowered. You explained your new design criteria on curtain drains. Mr. Robbie Robinson Page Two As stated before, I recommend using a higher perc. rate value than shown when sizing beds or trenches in shallow soils. These soils are fairly loose and can be easily compacted during construction or by the extended application of wastewater. I hope this letter will solve any problems Mr. and Mrs. Johnson were having. I would appreciate a copy of this letter with your initials on it indicating your agreement.
