Box 196650 Anchorage, AK 99519-6650 Subject: Central Birchwood, Lot 168-A - Modified Design Per your request of supporting soil data for the subject property's on-site wastewater reserve site, attached are adjacent properties soil data that show percolation rates ranging from 11 to 40 minutest per inch, with the majority around 20 minutes per inch. This data, along with the subject property's soil data and our own experience of the area demonstrate adequate soils exist for the reserve site. As mentioned previously, an additional testhole will be performed at construction for the reserve area. However with the existing testholes performed to date, an advanced wastewater system of 38'L x 2'W x 8'D with an application rate of lgpd/sf could be shown for the reserve. Although, this is conservative when actually a 2 gpd/sf application rate could be used for such a system. Also we have received authorization and you have been notified directly by Michael N. Anderson, P.E. to proceed with modifying the permitted design (OSP101150) as attached. If you have any questions, please contact me at 868-3792 / FAX 868-3793.

Per our discussion at your office today, please see the attached redlined design modifications. Due to the recently excavated foundation and existing characteristics of the lot, a lot line waiver to~' of property line is requested at this time.

There are no public or private wells within 200' of our proposed system location except as noted. There is no surface water within 100' of the proposed system and there are no known curtain drains within 50'. We do not expect there to be any adverse effect on adjacent lots by the development of this system. If you have any questions, please contact me at 868-3792 / FAX 868-3793.

Lambo, P.E. 4101 Arctic Boulevard · Suite 205 ,, Anchorage, Alaska 99503 March 17, 1982 Triad Engineering 6937 Old Seward Highway Anchorage, AK 99502 Attention: Dave Grenter Subject: Soils InvestigationlLots Dear Sir, sort AND MATERIALS ENGINEERING AND TESTING 907-276-4113 168A & 168B'in Eklutn.a, Alaska This letter presents the results of the soils investigation that we performed at your, request on Lots 168A and 1688 in the Birchwood Loop Road area. This work was requested to be per- formed to the minimum standards of the Department of Health and Environmental Protection (D.H.E.P.). These standards include the drilling of a soils boring to a depth of 2Q feet and the visual classification of the soil strata encountered by a field tech- nician. No laboratory analyses are requested. In soils which are visually classified to include more than 6% silt, (soil finer than the #20D screen size), a'percolation test is required to be performed in the area most likely to be developed for the ab- sorption system. Our procedure for performing the percolation test is to drill an additional boring adjacent to the soils log to the depth intended for percolation testing.. Coarse gravel is placed in the bottom of the boring. Four inch slotted and per- forated PVC pipe is placed within the percolation test boring and the annular space between the boring and the pipe is backfilled with washed gravel. The percolation boring is filled with water and allowed to saturate overnight. Percolation testing is per- formed the following day according to the standards presented in the E.P.A. publication "On Site Waste Water Treatment and Dis- posal Systems," Page 41, Table 3-8. All soils are visually classified in the field according to the Unified Soils Classification System presented on Plate 5 and the textural classstftcation system presented' on Plate 6. Per- forated 1-1/2 inch nominal standpipe was placed in the deep borings to allow for observation of free water level after drill- ing. In soils with a significant silt fraction, substantial time, often several days, is required to allow the free water level to stabilize. While no free water was observed in these observation standpipes the days when the percolation testing was performed, it should be noted that the free water level may fluctuate seasonally and annually in response to seasonal runoff or heavy rainfall. The results of the field investigation and percolation test- 1 trig are presented on the attached plates. The soils logs are presented on the standard D.H.E.P. form attached as Plates.2 and 3. The locations of the borings are presented on Plate 1. The .results of the percolation testing are presented on our form, Plate 4. We were requested to perform this investigation to the minimum standards required by-the Department of Health and En- vironmental Protection. It should be noted that, in accordance with these standards, the classifications of the soils are visual and performed by a soils technician. These classifications are. subject to change as they have not been verified by laboratory analyses. This work was performed for the the sole purpose of preliminary evaluation by the Department of Health and Environ- mental Protection of the suitability of the lots for on site sewer system development. Any extrapolation of this data for other purposes is not within the intent of the investigation or requested services. We trust the foregoing is sufficient to your immediate needs and is comprehensive within its limited scope. If questions arise or if we can be of any further service, please feel free to call.
