(AECS) performed a soils investigation on NW 1/4 ~ec~ion 15 T12N,'R3W, SM, Thfs trace lays to the south of Abbot Road between Jupiter and Our road. 100th Avenue borders this tract on the south., Preliminary Field Observations Landform: This tract lies in the Campbell Creek Watershed. The upper reaches of a tributary to Little Campbell Creek flows out of the area from NE to SW. Water and glacial processes have created the present landforms. The laed immediately adjacent to the creek is nearly level with a rough organic surface mapped as wetlands on the Municipal Wetlands Study. Further from the creek, steep slopes (in excess of 30%) are broken by nearly level benches. Total relief in this tract is approximately 110'. Vegetation: The low flatland near the creek is a black spruce woodland with woody shrubs (Sweet Gale, Marsh Rose, and Labrador Tea) dominating open areas. The low lying area to the east side of the tract contains a white spruce, paperbirch forest, which also thickly covers the slopes and benches away from the creek. Aspen are common on southern exposures. A mature white spruce, paper birch forest covers the highland on the north end of the tract. Soils: The Soil Conservation Service has mapped the soils of this area as Doroshin series and Homestead series. The Doroshin aeries, which is found in the lowland sections, commonly has a .surface layer of organic soil up to 50" thick. This horizon is underlain by either fine grained lacustrine deposits or compact gravelly glacial till. The Homestead series, which occupies the slopes and benches, is defined as having a surface layer of silt loam 5-20 inches thick. Below this is .a very gravelly glacial till. Soils Investigation Our soils testing was designed to determine what limitations, with respect to proper functioning of on-site septic systems, these soils have. Site features and soil properties included in the investigation were: I) Depth to bedrock (if present); ' 2) Depth to groundwater (if present); 3) Surface slope, and; 4) Soil permeability. The individual soil logs are included in Appendix A. Please refer to them for the discussion. Test Hole ~7 was canceled due to 1200 L~st 33rd Au~nu¢, Suil¢ ~ ·/~nc~or~q¢, ]~losko 99503 · {901) 276d361 inaccessibility. Discussion Shallow Soils: The low-lying area to the north of the drainage may have bedrock limitations. Our drill was unable to penetrate more than 7~ in this area. Please refer to Map A, Appendix B and note Test Holes 8, 9, 10, and 20. We are unable to determine if this is bedrock or a dense cobble strata. We suspect a cobble layer because other testholes throughout the tract met refusals within 5' before successful penetrations. Further tests~ preferably with a b~ckhoe, will be required to determine conclusively if there are bedrock limitations in this area. All other s~ctiona of this. iract do not have bedrock limitations. Groundwater: We considered an area unacceptable if groundwater was encountered at less than 4'. No test holes hit water at less than 4'. Groundwater between 4' and S' was considered a severe limitation, requiring an engineered septic system. Test Hole $1 on the extreme north end of the tract had groundwater at 4'. This test hole was in a swale and we anticipate greater depths to groundwater nearby. All other test holes hit groundwater at 12' or more, or not at all. Groundwater at these depth~ does not present any limitations in septic system use. -The lowland near the drainage is designated as wetlands in the Anchorage Wetlands Study and is not suitable for on-site septic systems. Slope: Slopes in this tract, according to Municipal topo maps, commonly exceed 25%. However, these are often broken by nearly level benches. Please .refer to Map B, 'Appendix B for areas w~th slope limitations. Lots should be designed to include these benches in order to support an on-site septic system. Soil Permeability: Two test holes, # 17 and #4, failed the percolation test. These results are contrary the norm. We expect positive results in these areas with more testing. All other areas tested passed the percolation tests. Some soils were of high enough quality to be given visual ratings. Conclusions: We have broken the tract into 3 categories based on ~oil characteristics obtained from our testing. 1) Areas with no soils limitations 2) Areas with amendable soils limitations 3) Potentially acceptable areas with inconclusive testing We recommend the following for each category: Category #1 Approve as platted ,Category ~2 Category ~3 Lot design to include areas for original system plus two alternatives. Approve as platted conditional on further soil testing. If you have any questions, or if we can help you in the future please feel free to call the office.
