Box 196650 Anchorage, Alaska 99519-6650 Fax 249-7847 Re: Woodhaven Heights Lot 2 To Whom it may concern This is a revision letter from the original submittal package. A grading plan was submitted to the MOA in 2006 and approved by James (Jay) Crewdson, P.E. on 3-15-06. I have coped sections of the approved site plan for this submittal, showing that the slopes are less than 25percent. Two new test holes were excavated last week in the area which has the best possibility of supporting a leach field. Both test holes had the same material GP/SP & GM/SM, see soil logs, with no water observed during the excavating. Test hole 42 was dry after the seven day monitoring period but water was measured at 10 feet, in test hole #3. This design will consist of two 2000 gallon tanks, one will be a standard 2000 gallon single compartment tank and the other one will be a 2000 gallon Advantex tank with a pump basin and duel pods as shown on the plan sheets. The maximum slope around the preliminary design is 10 to 15 percent per the original design. There are no public or private wells within 200 feet of the proposed system location. There is neither surface water within 100 feet nor any known curtain drains within 50 feet of the proposed system. None of this development will have any adverse effect on the adjacent lots. A well log is not available therefore a camera will be used to verify the minimum casing depth. If you have any question please call me at 727-8864. Sincerer Michael N. Anderson, P.E.
