Drilled piers for support of play structure and/or shade structures, including allowable <br />skin friction, minimum diameter and embedment depth, and resistance to lateral loads. <br />c. Anticipated total and differential settlements and discussion of liquefaction potential <br />(if applicable). <br />d. Provision of state-mapped 2019 CBC seismic design parameters (no site-specific <br />ground motion hazard analysis is included). <br />e. Site drainage. <br />f. Mitigation of stormwater runoff and discussion of the feasibility of bioretention areas <br />(using soil index testing to classify soil per USDA Hydrologic Soil Group), including <br />presentation of percolation test results. <br />g. Slab-on-grade and exterior flatwork recommendations; <br />h. Asphalt concrete pavement sections based on assumed traffic index values and R- <br />Value test results; <br />i. Recommendations for site preparation, earthwork, and fill compaction specifications; <br />and <br />j. Construction considerations and limitations; and <br />6. A brief discussion of the corrosion potential of near-surface soils encountered during our <br />subsurface investigation based on the laboratory corrosion screening test performed. <br />Consultant will convert the two 5-foot-deep borings into percolation test holes. Upon <br />completion of the percolation testing, the test holes will be backfilled with sand and the <br />upper approximately six inches will be patched with topsoil or patched with rapid setting <br />concrete. <br />Consultant shall provide a letter from a geotechnical engineer indicating that the design <br />is in accordance with the recommendations of the geotechnical report and that any <br />comments have been addressed. <br /> <br />Deliverables: <br />Geotechnical Report (Draft and Final) in pdf format. <br />Letter indicating compliance with recommendations. <br /> <br />Task 9: Arborist Report <br />Consultant will provide an arborists report containing a tree inventory, map, preservation <br />guidelines, and protection plan for all trees within the project limit that have a trunk <br />diameter of 6 inches or greater measured 54 inches above grade. <br /> <br />Deliverables: <br />Arborist Report <br /> <br />Details of Deliverables <br /> <br />DocuSign Envelope ID: 73B64E61-9591-470B-9CFE-9E9CD49407D4
