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 trenches 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 wlth this report. If you have any questions, please contaot our office. Very truly yours, CONSTRUCTION TEST LAB ames D.

Mr. Goodhue's subdivision plan, as shown by the preliminary plat submitted to your office, is to divide the 18.2 acre tract into 7 lots, averaging approximately 2.6 acres per lot. As stated in our application for preliminary approval, we requested a waiver from furnishing soils information on each lot because of the consistency of the soils in the area (shown by the test holes submitted) and the proximity of these test holes to the subdivision site. Also, it is almost impossible to reach the proposed subdivision site with drilling equipment because the access road has not yet been completed. Based on the letter furnished to your office by Construction TestLab, we request that the waiver for soils information be granted for a period extending through the preliminary approval stage of the project. Mr. Goodhue agrees that prior to recording the final subdivision plat, soils tests will be performed on each of the 7 lots in the subdivision and submitted to your office for approval. Thank you for your consideration of this request.

None of the holes are located within the tract which is proposed to be subdivided, however, based on test results from the soil samples obtained from test hole #1, #6, #7, #8 & #9, which are adjacent to Tiaga Subdivision, we feel that the subsurface soils will be very similar. The soils encount- ered in these previous test holes were classified as coarse sandy gravels (GP-GW) or silty sandy gravels (GM) and are suitable for on-site sewage systems.
