Ken Mercer Sports Park Skatepark r r m Scope of Services March 1, 2021 design Page 3 of 9 group • A description of the project including a vicinity map and site plan showing the approximate locations of our borings • A description of the subsurface investigation, logs of borings, and results of laboratory tests • A description of the surface and subsurface site conditions encountered during our subsurface investigation, including depth of free groundwater if observed in our shallower hollow stem auger borings • A description of the site geologic setting and associated geology related hazards, including faulting, liquefaction (within the depth of our borings) • Conclusions and recommendations related to the geotechnical aspects of: o Shallow spread footings and mat foundations, including allowable soil bearing pressure, minimum embedment depth, resistance to lateral loads, friction coefficient,and modulus of subgrade reaction o Recommendations for drilled piers for support of light poles and/or shade structures, including allowable skin friction, minimum diameter and embedment depth, and resistance to lateral loads o Equivalent fluid pressure for active, at-rest, and passive pressures as well as seismic increment values for below grade walls o Recommendations for resisting potential buoyancy forces, such as the use of a pressure relieve value or measures to resist uplift pressures o Anticipated total and differential settlements and discussion of liquefaction potential (if applicable, within the depth of our borings) o Provision of state-mapped 2019 CBC seismic design parameters (no site-specific ground motion analysis is included) o Slab-on-grade and exterior flatwork recommendations o Recommendations for site preparation, earthwork, and fill compaction specifications o Construction considerations and limitations; and a brief discussion of the corrosion potential of near-surface soils encountered during the subsurface investigation based on the laboratory corrosion screening test performed. BSK will also obtain a bulk sample at the location of their boring near the potential parking lot expansion and conduct a Resistance-Value)R-Value test for the purpose of providing flexible pavement design. They will provide several design alternatives based on the R-Value test and assumed or provided traffic index values. Deliverables: • One (I) geotechnical evaluation including three (3) borings up to 15-20 feet in depth and report of findings in PDF format
