The investigation complied with those procedures required by the Municipality of Anchorage Department of Health and Environmental Protection. This investigation, which was accomplished on September 23, 1977, consisted of a test hole excavated to,depth of 12 feet below the existing ground surface. The test hole was sited according to your instructions and its location is shown in attached Drawing A-01. Excavation was accomplished with a backhoe. Material exposed in the trench was continuously monitored by an experienced engineering geologist. The topography at the excavation site is generally horizontal. At the time of the investigation, the site had original vegetation consisting of birches and low brush. The top of the test hole was located at original ground surface. The soils encountered in the excavation are shown in the test hole log in Drawing A-01. The symbols used in Drawing A-01 are explained in Drawings B-01 and B-02. This log displays specific conditions encountered at the test location. However, subsurface conditions may vary in other parts of the lot without any apparent surficial evidence of the change. G~_roundwater was not encountered.~Bedrock was not encountered. At the time the hole was excavated, seasonal frost was not present and permafrost was not encountered. An adjacent trench was dug to a depth of 5'. A percolation test was performed in a one-foot diameter hole dug within the trench to a depth of approximately one foot. The data in Table 1 show average infiltration from the depths indicated to the bottom of the hole. The measured percolation rate was 25 minutes per inch. We appreciate this opportunity to be of service to you. Please contact us if you have any questions concerning this letter or if we can be of additional service.
