The purpose of these test borings was to determine the soil types occurring on each lot within the subdivision and to establish the drainage area required in the leaching 5renches for on-site sewage systems. The test borings were drilled in the exact locations as directed by Mr. Goodhue, and, as shown on the enclosed subdivision map. In test holes ~1 and ~2, a visual analysis was made to determine the required drainage areas. In test holes #3, 4, 5, 6, & 7 percolation tests were performed to determine the required drainage area. The results of these tests are included with this report. If you have any questions, please contact our office. Very truly yours, CONSTRUCTION TEST LAB ./ James D.

Because the.Greater Anchorage Area Borough has established their criteria for the soils suitability and the seepage area required per bedroom based on the unified soils classification system, we used the grain size distribution curves in the referenced tests to establish the unified classification of the soils. This classification, in addition to the Alaska Testlab .soil triangle classification, is tabulated in Table 1. The Greater Anchorage Area Borough criteria has been established as follo%*zs: Unified soils Classification GM SW SP SM ML CH Seepage Area ft.2/Bedroom 85 225 125 150 250 275 350 0 Q 0 0 0 U Nh Q · 0 P~ fi} ~Q · 0 0 Tryck, Nyman & t{ayes April 18, 1974 The Greater Anchorage Area Borough hasestablished that soils classified as silt (A~), seepage area = 275 ft.2/bedroom~ or clay (CM) ~ seepage azea = 350 ft.Z/bedroom, are not sufficiently permeable to accept seepage pits. For further restrictions and information we draw your attention to the Greater Anchorage Area Borough Ordinance 28-68, (Appendix B). The test holes, samples and tests were by others, however, they appear reasonable with regard to the conditions expected in this general area, as. observed in our 1973 walkover review of the site.
