Home construction was delayed until late fall. Site final grading was conducted 5/14-15/16 that fulfilled the 50 foot distance for the slope waiver. Installation of 6" of topsoil and seed per 15.65.060.1.6&7 were placed mid-May 2016. Home owners moved in early June 2016. High ground water monitoring was complete Saturday 4/25/15 and stayed consistently at 7.5 feet from original grade. No change in design was required. Septic tank installed was a 2,000 gallon with a maximum fill of 5.25 feet. All pipes were HDPE and were 4 inch in diameter. Separation fabric used was Mirafi 140N according to ADEC regulations. The absorption field dimensions installed was 20 foot wide with four runs of 5' wide by total length of 96 foot entering in the middle of the field. I apologize for the delay in getting these closes out documents. There was miscommunication on delivery of the package between BC Excavating and myself. I have misplaced my original electronic copy of this letter from 2016 and having to redo it now. Delivery of this for my side job is not easy as I work my normal 40 hour job in Palmer the same hours as you do in Anchorage. I have scheduled a personal dental appointment this Friday in Anchorage so I will be dropping off everything finally. Please contact me for any additional information.

Following the previous work of Mr. Kinney (RPKA), attached letter and maps of septic system investigation and proposed well locations. From that report, TH3 has a perc rate of 17 and my average from Perc #1 &#2 was 18.5 which give us an application rate of 0.4 for a 5 bedroom home that equates to 1,875sft. We request your approval for a waiver on the 15 foot maximum width per ! 5.65.60, H5. We would like to install a four leg system with 5 foot max separation, therefore request a width of 20 foot wide to stay with in the 1 O0 foot max length and have a 95 foot long bed. Reasons we cannot go less wide and longer are the original slope across the length of the field is 2-3% which is right at our 4 foot limit to potential ground water with the adjacent test holes from TH3 on the east end. On the west end we are about 30 feet away from a natural weeping drainage (underground stream) through a two foot thick pure sand layer. Though we didn't find ground water from Perc Test #1 & #2, we have selected this natural bench site from trial and error with our findings. We placed a high water monitoring tube 9.5 feet down the high water evaluation check about 5 feet from the south west side of the alternative field, according to AMC15.65.060.B.4. Construction equipment will not drive on the bottom of the bed system or above the bed system during construction activities. The reach of the 200 Hitachi is more than adequate to construct a 20 foot wide bed system from access to either side. We discussed the one south east corner barley not meeting the 50 foot set back from a 25% slope. The land owner had in his future development plans to create a soccer field in this area. As a mitigating factor, he will use the building site foundation excavation for the lower fill in the south and south east corner to ensure a slope less than 25% is met at a minimum distance of 50 foot. We have located the east end of the bed system 28 foot from the perc test hole TH3 from 4/29/14 testing and about 30 feet from TP5, I 1/15/14. The bed runs parallel to the contour lines. Cross slope a-A is about 7-9% and parallel slope b-B is about 2- 3%. Due to the calendar limitation of monitoring high water from May - October, even though last fall and this spring were considerably warmer and the frost is almost complete gone from the site, we are using TH3 as our design control for our high water Page 1 WALDEN Construction Consulting and Engineering, LLC mark datum of 5.75 from original ground. Therefore, we have added ~ /v~0A gradation sand in our possible fill locations where we will be above original ground. This changes our leach field area to a mound and we added 6" minimum of topsoil and se~c~per 15.65.060.1.6&7. We changed the separation fabric to silt barrier that will co~ply with the language according to 15.65.060.E.6 and will use material specification per ADEC of Typar 3401, Mirafi 140N, or equivalent filter fabric. Septic tank will be a 2,000 gallon by owner preference instead of the 1,500 gallon minimum capacity required for a five bedroom. All solid pipes will conform to 15.65.040, HDPE or PVC D3034 and be 4 inch in diameter. High ground water monitor tube even though not complete until this Saturday with the 7 day monitoring has stayed consistently at 7.5 feet from original grade. Please contact me for any additional information.
