Please see my responses to your comments below, and attached revised drawings. I look forward to hearing from you soon.

Bowman <cbowman@hdlalaska.com> Subject: Change Order - Loma Est L1 B1 review comments OSP221371 Loma Est L1 B1 Hello Mark, Thanks for your patience. Here are my comments on this change order: I. C-101 Your visual description of the existing trenches differs than what you submitted to us at permit request. Did you confirm visually that this is how the existing system is orientated? This is important because we require horizontal separations between the new field and the old. See 15.65.210 B1g The existing system location as shown on the plans is based on the following information ® The contractor excavated into the side of the existing system when setting the new septic tank ® Reviewing the MOA records more closely, the existing system was located as shown It is relevant to note the survey sheet provided by our client does not appear to match with what we observed in the field. The proposed system should be able to have greater than 6 FT offset to the existing field, and I have revised the drawings to indicate this. 2. C-101: Bed width is controlled by 15.65.210 D2c You can justify bed width being larger if you desire. We propose to install a 24 FT x 24FT bed soil absorption system wider than 15 FT specified in 15.65.210 because we want to maintain adequate separation from the existing soil absorption system and available area on the lot is limited. The lot will allow for the bed soil absorption system (SAS) to be constructed without tracking equipment over the SAS; I have added a note to the detail drawing for the SAS. 1 3. G-003 is it not desirable to have the DESIGN POINT closer to the OPERATING POINT on the pump curve? The design point shows based on the input parameters the feet of head and flow rate required. The operating point shows how the system will perform with the selected pump. The operating residual head will be higher than the 5 FT residual design point. The residual head will be approximately 25 - 26 FT (11psi) and will keep the system adequately pressurized. 4. V-101: existing trench description doesn't match what is shown on C-101. Please coordinate. See comment #1 above I have remove V-101 from our plan set as discussed. 5. V-101: can you show the location of the new test pit dug in June 2023 on this page with the 30' radius? I have removed V-101 from our plan set. 6. C-101: can you show all test holes dug in support of this project on this page with 30' radii around each? Yes. The test holes were originally not included because they are greater than 30' away from proposed soil absorption system. Please see revised C-101. 7. C-103: bottom of bed sewer rock looks to be at approximately 634'. This is approximately 2.5'— 3.5' bgs. Please justify that this will all be draining into the soil strata that you performed the perc test in. Perc test was performed at 3.5' bgs. Looks like from your soil log there is a different layer between 2 — 3.5'. Or justify that this is all similar soil. The bottom of the sewer rock is approximately at 3 FT below ground surface and the soil absorption system will be draining into the same soil strata as the perc test at 3.5 FT. I would like to explain the test pit log. The soil has the same classification from 2.0 FT to 7.5 FT (sp/SP). The soil changes on the test pit log are identified by the lines that run halfway across the page under subsurface material. According to our geotech group, the uppercase SP at 3.5 FT identifies lab testing was used for the soil classification and not a change in soil type. The sm classification at 8.0 FT is not capitalized because testing to distinguish between silt or clay was not performed. 8. C-301: please clarify native sand below sewer rock? This makes it look like you are installing a sand filter layer below the sewer rock. Not needed since the soil is classified as SP. The native SP soils will be used, not a sand liner. I revised detail drawing to clarify. 9. C-301: laterals should be located in the middle vertically of the sewer rock. it appears you have the laterals located towards the top of the sewer rock. I have revised the drawings to indicate 2" of sewer rock above the laterals.

CE tTs3•U �PROFES$10NA, Subject: Geotechnical Memo Platt Residence Test Pit & Percolation Testing Loma Estates L1 131 HDL Engineering Consultants, LLC (HDL) conducted a test pit and percolation testing in support of a wastewater system replacement at the Platt residence located at 16910 Bettijean Street in Anchorage, Alaska (Site). This geotechnical memo is subject to the attached limitations. HDL conducted a falling head percolation test in an excavated test pit (TP -01) near the proposed soil absorption system on May 31, 2023. We conducted the test in general accordance with the Environmental Protection Agency's Falling Head Percolation Test Procedure by placing a 4 -inch diameter standpipe in a bench adjacent to TP -01. The final depth of the standpipe was approximately 3.5 feet below the existing ground surface (bgs). See HDL TP -01 on the attached Site Plan for the test pit location. The test pit encountered an organic mat followed by layers of poorly graded sand with varying amounts of silt and gravel extending to the test pit termination depth. HDL collected grab samples at select depths and returned them to HDL's laboratory for testing. See the attached Test Pit Log for detailed soil information and results of the laboratory testing. HDL observed a groundwater seep during excavation at a depth of approximately 7.5 feet bgs. HDL installed a slotted 2 -inch PVC pipe in TP -01 to monitor groundwater levels at the Site. On June 8, 2023 we measured groundwater in the PVC pipe at a depth of approximately 8.75 feet bgs. We adjusted the groundwater depth by 1 foot in accordance with the Municipality of Anchorage code 15.65. The resulting adjusted seasonal high groundwater level at the Site is 7.75 feet bgs. Due to the permeable nature of the soil, HDL collected 7 measurements of the time it took for the water level in the standpipe to drop 6 inches. Table 1 presents the results of the percolation test. 3335 Arctic Boulevard, Suite 100, Anchorage, Alaska 99503 202 West Elmwood Avenue, Palmer, Alaska 99645 907.564.2120 907.746.5230 Geotechnical Memo, Platt Residence Percolation Testing June 21, 2023 Table 1 - Percolation Test Results Drop in water level(inches) 6.00 Time Interval (minutes) 0.96 Percolation Rate (minutes per; inch) 0.16 6.00 1.05 0.18 6.00 1.13 0.19 6.00 1.19 , 0.20 6.00 1.27 0.21 6.00 1.33 0.22 6.00 1.35 0.23 Per the Falling Head Percolation Test Procedure, the last measurement taken represents the percolation rate.

HDL Engineering Consultants, LLC (HDL) prepared this report on behalf of, and for the exclusive use of our Client for the stated purpose(s) and location(s) identified in the Proposal for Services and/or Report. Use of this report, in whole or in part, at other locations, or for other purposes, may lead to inappropriate conclusions; and we do not accept any responsibility for the consequences of such use(s). Further, reliance by any party not expressly identified in the agreement, for any use, without our prior written permission, shall be at that party's sole risk, and without any liability to HDL. 2. If substantial time has elapsed between submission of this report and the start of work at the site, or if conditions have changed because of natural causes or construction operations at or adjacent to the site, we recommend that HDL be retained to review this report to determine the applicability of the conclusions considering the time lapse or changed conditions. Standard of Care 3. HDL's findings and conclusions are based on the work conducted as part of the Scope of Services set forth in the Proposal for Services and/or Report, and reflect our professional judgment. These findings and conclusions must be considered not as scientific or engineering certainties, but rather as our professional opinions concerning the limited data gathered during the course of our work. If conditions other than those described in this report are found at the subject location(s), or the design has been altered in any way, HDL shall be so notified and afforded the opportunity to revise the report, as appropriate, to reflect the unanticipated changed conditions. 4. HDL's services were performed using the degree of skill and care ordinarily exercised by qualified professionals performing the same type of services, at the same time, under similar conditions, at the same or a similar property. No warranty, expressed or implied, is made. Subsurface Conditions S. The generalized soil profile(s) provided in our Report are based on widely -spaced subsurface explorations and are intended only to convey trends in subsurface conditions. The boundaries between strata are approximate and idealized, and were based on our assessment of subsurface conditions. The composition of strata, and the transitions between strata, may be more variable and more complex than indicated. For more specific information on soil conditions at a specific location refer to the exploration logs. 6. Unanticipated soil conditions are commonly encountered and cannot be fully determined by merely taking soil samples or advancing borings. Such unexpected conditions frequently require additional expenditure to attain a properly constructed project. Therefore, some contingency fund is recommended to accommodate such potential extra costs. 7. In preparing this report, HDL relied on certain information provided by the Client, state and local officials, and other parties referenced therein which were made available to HDL at the time of our evaluation. HDL did not attempt to independently verify the accuracy or completeness of all information reviewed or received during the course of this evaluation. 8. Water level readings have been made in test holes (as described in the Report) and monitoring wells at the specified times and under the stated conditions. These data have been reviewed and interpretations have been made in this Report. Fluctuations in the level of the groundwater occur due to temporal or spatial variations in areal recharge rates, soil heterogeneities, the presence of subsurface utilities, and/or natural or artificially induced perturbations. The water encountered in the course of the work may differ from that indicated in the Report. 9. HDL's services did not include an assessment of the presence of oil or hazardous materials at the property. Consequently, we did not consider the potential impacts (if any) that contaminants in soil or groundwater may have on construction activities, or the use of structures on the property. 10. Recommendations for foundation drainage, waterproofing, and moisture control address the conventional geotechnical engineering aspects of seepage control. These recommendations may not preclude an environment that allows the infestation of mold or other biological pollutants. Compliance with Codes and Regulations 11. We used reasonable care in identifying and interpreting applicable codes and regulations. These codes and regulations are subject to various, and possibly contradictory, interpretations. Compliance with codes and regulations by other parties is beyond our control. Additional Services 12. HDL recommends that we be retained to provide services during any future: site observations, design, implementation activities, construction and/or property development/redevelopment. This will allow us the opportunity to: i) observe conditions and compliance with our design concepts and opinions; ii) allow for changes in the event that conditions are other than anticipated; iii) provide modifications to our design; and iv) assess the consequences of changes in technologies and/or regulations.

Engineer's Comments: In conducting this evaluation, GEG, VD. attempted to provide a thorough, conscientious engineering analysis of the system in accordance with ADEC and MOA DSD Guidelines B Regulations. The reported results described 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 soils condition, groundwater levels that may fluctuate during the year, and the water usage of the family being served by the system. These conditions are outside the control of the evaluator of the system. Satisfactory test results do not guarantee future performance of the system, nor do they guarantee that there are no hidden defects or encroachments. GEG, LTD. can therefore not provide any warranty or future estimate of how long the system will continue to meet the operational requirements of the ADEC or MOA DSD.
