Groundwater was encountered in 10 of the 12 soil borings at depths ranging from about 71/2 <br />to 191/2 feet below the ground surface, corresponding to elevations ranging from about 963 to <br />881 1/2 feet above mean sea level. We generally do not anticipate that groundwater will be <br />encountering during grading activities but could be encountered during utility construction <br />and dewatering could be required. <br />With the building pad prepared as recommended, it is our opinion the footings can be <br />designed for a net allowable bearing pressure up to 3,000 pounds per square foot (psf). <br />The following sections provide recommendations for foundation design and construction. <br />4.3 Site Grading Recommendations <br />Excavation Structures exist on the project site that will be removed/ demolished to make way <br />for the proposed development. We recommend that all building remnants including former <br />foundations, footings, floor slabs, foundation walls and underground utilities be removed <br />from within the building, roadway, utility and oversize area. <br />We recommend that all vegetation, topsoil and any soft or otherwise unsuitable soils, if <br />encountered, be removed from below the proposed building and oversize areas. Table 4 <br />below summarizes the anticipated excavation depths at the soil boring locations. Excavation <br />depths may vary and could be deeper. <br />Table 4.
