City of Gladstone Project LA1BTFM7PNQ6 Flora Park (Phase II) Geotechnical Report.

The document is a Geotechnical Engineering Report for the Flora Park Upgrades project in Gladstone, MO. Here's a summary of the report: **Project Description:** The project involves the construction of a new restroom facility and paved parking and drives at Flora Park. The site is approximately 0.7 acres and is relatively flat with a grade change of about 7 feet. **Subsurface Investigation:** Three auger borings were drilled at the site to a depth of about 8-15 feet. The borings encountered predominantly clay soils, with some areas of weathered limestone and shale. Standard Penetration Tests (SPT) were performed to evaluate the consistency of the soils. **Laboratory Testing:** Laboratory tests were performed on soil samples collected during drilling, including visual classification, moisture content, Atterberg limits, and dry unit weight tests. The results indicate that the soils are lean clay with moderate swelling potential. **Groundwater:** Free water was not encountered during drilling, but the groundwater level is expected to fluctuate with precipitation, site grading, and drainage conditions. **Geotechnical Considerations:** The soils encountered are compressible and may be unstable, requiring correction during site preparation. The report recommends stripping any topsoil, vegetation, and other deleterious materials from the site, as well as implementing erosion control measures. **Site Development:** The report recommends site preparation, including cut and fill operations, to achieve design grades. It also suggests that additional cuts and fills may be required to improve surface drainage. **Recommendations:** * Strip any topsoil, vegetation, and other deleterious materials from the site * Implement erosion control measures, such as proper site contouring and silt fences * Perform cut and fill operations to achieve design grades * Consider additional cuts and fills to improve surface drainage * Use engineered fill placement to ensure stability and compaction of the soils Overall, the report provides a comprehensive geotechnical evaluation of the site and recommends measures to ensure the stability and safety of the proposed construction project.
