Horton 11241 Slater Avenue Northeast, Suite 200 Kirkland, Washington 98033 Attention: Tony Brandolini Subject: Final Report Earthwork Observation, Compaction Testing and Consulting Services Maple Highlands 16210 Southeast 134th Street Renton, Washington Dear Tony: Earth Solutions NW, LLC (ESNW) representatives provided earthwork observation, compaction testing and consulting services at the subject site. ESNW provided the referenced geotechnical engineering study and reviewed the referenced plans for the project. Our services included providing earthwork observation and compaction testing on a part-time basis from June 17, 2022 to September 23, 2023. ESNW representatives made 79 site visits to observe or test stormwater vault foundation subgrade, lot fills, utility trench backfills and pavement subgrade. ESNW representatives conducted 178 field density tests in accordance with ASTM Test Designation D6938 (Nuclear Gauge Method). Five representative soil samples were returned to our laboratory for analysis of the maximum dry density and optimum moisture content in accordance with ASTM D1557 (Modified Proctor). Density test results indicate adequate compaction of at least 95 percent at the tested locations. ESNW representatives observed stormwater vault foundation subgrade to be dense and suitable for vault support. ESNW representatives observed pavement subgrade to be dense and suitable for asphalt. ESNW representatives observed erosion control measures to be maintained in accordance with the project requirements and our recommendations. Based on our observation and testing, and to the best of our knowledge, the earthwork was accomplished in accordance with the project plans and our geotechnical recommendations. D.R.

The observations, recommendations, and conclusions provided in this field report are preliminary until reviewed by the ESNW project manager. As requested, ESNW rep was on site to observe over excavation of the subgrade for Road A. Road Subgrade Observation ESNW rep observed the contractor over excavating the areas of deflection, as per ESNW rep’s recommendation. The subgrade was over excavated to approximate depths of 6 to 24-inches (6 inches of over exaction where shallow utility crossings were encountered). The contractor backfilled these areas with crushed rock and will compact the soil by end of day.

As requested, ESNW rep was on site to observe a proof roll of the bottom half of the road subgrade for Road A. Road Subgrade Observation ESNW rep observed the contractor use a loader, with a full bucket of rock, proof roll the subgrade for Road A. One area of moderate deflection were observed and ESNW rep recommended the contractor over excavate these areas to a depth of 2-feet or until firm conditions are reached. The grade should be restored using crushed rock compacted with a hoe pack or vibratory drum roller. As an alternative to over excavation, the contractor can cement treat these areas. ESNW rep should observe another proof roll prior to paving.
