Our services were <br /> completed in general accordance with the proposal signed by you on November 5,2020. <br /> The site is rectangular in shape, and covers 0.24 acres in combined area. The site is currently occupied <br /> by a commercial structure which was historically a residence on the southern portion, with asphalt- <br /> paved parking areas surrounding the structure. The property is bordered by Broadway to the west, an <br /> alley to the east, and neighboring commercial parcels to the north and south. The site is relatively level <br /> to gently sloping. We understand the project will include construction of a 2-story addition to the <br /> existing structure, with frontage and accessibility improvements, and we have been requested to <br /> provide this report for geotechnical recommendations for development considerations for the proposed <br /> additions. <br /> Specific stormwater plans were not available at the time this report was prepared. However, we <br /> understand that stormwater is likely to be directed into on-site infiltration systems, if feasible. We have <br /> been requested to provide our opinion on the feasibility of stormwater infiltration into the site soils. <br /> We explored the subsurface conditions within the site by excavating six hand augers to depths ranging <br /> from 3.5 to 4.7 feet below the existing ground surface. Our explorations indicated that the site was <br /> underlain by relatively shallow undocumented fill soils with medium dense or better, native glacial till <br /> soils at depth. <br />
