May 31, 1983 Mr. Robert Robinson, Engineering Manager Department of Health & Environmental Protection 825 L. Street Anchorage, Alaska 99501 MUNICIPALITY OF ANCHORAGE _ DEPT. OF HEALTH ENVIRONMENTAL PROTECTION MAY 3 RECEIVED Dear Mr. Robinson: Per our d~scussion I have ~0bked over the soils on the proposed lots 7, 9 and 10,' Block 4 South Fork West and have prepared a mound design for lot 10. This design would be applicable for lot 7 but ~s larger than needed for lot 9. A four bedroom house was assumed. For all cases the surface loading rate is within~h'e criteria for mound design. I estimate the cost of Ehis system to be between $22,000 and $28,000. The price could be reduced ~f the silty gravel could be mined from the lot or from a nearby site. This cost is p~edicated on ~e water levels on these lots remaining at or near .l foot below ground level. If the road cut will rem0~e the Water problem as I e~xpec~ the need for the mound ~0uld be eliminated or the height '~eatly reduced. This would 6~f ~course reduce building construction costs. Since these lots~ are quite .large~I recommend that the lots be plotted as presented' with a no~e on the plot to the effect that these lots ~/ill ~equire engineered mounds unless subsequent soil~~ ~tests~ st~ow that a conventional system can be installed. If you have any questi~hs please let me know. your consideration.

Soils in the subdivision vary greatly, from impermeable blue silts to fairly clean gravels. The main problem with this subdivision is its lack of proper drainage--almost all soils are wet, with a water table during breakup just below the surface. Indeed, the 3 lots which failed perc tests--Lots 7, 9, & 10 of Block 4-- contain soils which might perc if the water were drained off the lots, as it is difficult for water to flow into soil that is already saturated. The fact that the soils are presently saturated suggests that they are permeable, which is a necessary requirement for on-site septic systems. But this is an empirical observation and an accurate test is essential. In some cases, per¢ tests were actually run over the water table. The procedure for such a test was as follows: immediately after the perc hole was drilled, 6" of water would be added and measurements would be taken. The water would rise instead of dropping, and measurements would be taken until a very small rise was noted, suggesting that equilibrium had been reached, and as much groundwater was flowing into the perc hole as was flowing out. Six inches of water then would be poured over that and the drop would then be measured. There are several problems with this method. For one thing, the rate of return of groundwater to its equilibrium point was not constant enough to use as a measurement that a perc rate could be based on. Second, measurements made after groundwater equilibrium was supposedly reached were not constant. This suggests that groundwater still may have been flowing in sporadically, thus giving an erroneous perc rate. Third, it is questionable whether these above-the-groundwater perc tests were performed in representative soil. Due to the breakup water flowing through the soils, it is possible the perc test water merely flowed out through an existing underground channel, thus not giving a true idea of the general permeability of the soil. Due to these various problems, no soils ratings were assigned to lots in which these perc tests were run. The readings indicate that the soil is in fact permeable, but a numerical value showing the soil rating cannot conscientiously be calculated at this time. Perc rates for the 3 failing lots would fall in the range between 220 and 317 square feet per bedroom if data obtained from over-the-water table perc tests were used. It is even possible that the true soil rating would be lower than this if the ground were properly drained. 1200 ~Jest 33Pti ]~uenue, Suite [~ ~, ]~nchoro§e, Aloska 99503 · {907) 276-1361 Draining the water from the entire area is absolutely necessary if homes are to be built on the land. Even if the groundwater problem is only seasonal, it must be taken care of. Presently the water level is 6" below the surface on many lots. If a septic system had been built on such a lot during a dry season, no matter how permeable the soil around is, the system would fail when breakup-related groundwater rose and backed up into the house. Groundwater problems similarly would damage the basement. There are a number of possible solutions to the ground water problem. One is to put curtain drains on every lot having a shallow water table, behind the homes and septic systems. These drains, though expensive, have proven very effective. Another solution would be to dig trenches on the upper slopes of the subdivision, cutting off the water supply to the lots below. It is our opinion that South Fork West Subdivision may be platted as presently submitted. Although 3 lots had failing per¢ tests (as discussed above), it is felt that on-site septic systems could safely be built on these lots if the systems are carefully engineered and if curtain drains are built to divert the groundwater for each lot. If a septic system is built on any of these 3 lots without such engineering, it will positively fail. Again, the criteria for believing these lots to be adequate for on-site septic systems is as follows: 1. The soils are visibly adequate (silty sands and silty gravels). The soils were saturated, and groundwater visibly flowed into the perc holes, indicating permeability. Although readings of perc-water drops were few and inconsistent, they suggest that water does flow through the soils at a fast enough rate to support an on-site septic system.
