To maintain consistency with the approved soil test data and verified site conditions, the drain field was relocated to correspond with the field verified location of the existing test hole. Additionally, the original configuration of two 35 -foot long trenches was revised to a single 70 -foot long trench at the proposal and recommendation of the system installer.

Soils: A test hole was performed in the vicinity of the proposed system on this lot by Pannone Engineering Services, LLC on 10/14/2020. Groundwater was not observed during the excavation of the test hole, and bedrock was not encountered. Groundwater was not observed in the test hole monitor tube after 7‐daysor at any time since. Based on the results of the percolation test and overall soils appearance an application rate of 1.2 gpd/SF was used for the design of a conventional wastewater treatment system in the area of the test hole.  The soils encountered and sieve tested so far in the subdivision have conformed to a sand classification with <50% passing a #4 sieve (including neighboring L13). A sieve analysis will be performed on the soil in the area of the drain field to verify the in‐situ sand, and a change order will be submitted if the soil is found to require a sand filter. 2. Soil Absorption System Design. a. See Sheet 1 of the design package. 3. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain field. 4. Topography: See attached site plan for area topography. There are no steep slopes in the vicinity of the drain field. 5. Drawing Markings: The Drawings are marked “For MOA Review Only”. When written notification that the review is complete and no further comments are received from MoA On‐Site Department, the note will be removed and “For Construction” drawings will be issued. The proposed installation will not affect the future development of this or the surrounding lots. If you have any questions or concerns, please contact me at (907) 745‐8200.

In conducting an adequacy test, I attempt to provide a thorough, conscientious engineering analysis of the system in accordance with ADEC & MOA guidelines and regulations. The reported results describe the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily identifiable features. The operational life of all wells and septic systems depend on the local soil condition, ground water levels that may fluctuate during the years, and the water usage of the people served by the system. These conditions are outside the control of the evaluator of this system. All systems eventually fail, and satisfactory test results do not guarantee future performance if the system, nor do they guarantee that there are no hidden defects of encroachments. Therefore, we cannot provide any warranty of future performance, nor can we estimate the remaining life of the system. The content of this report is for the sole benefit of the owner listed above.
