EXHIBIT B Description of Proposed Investigations 1. Property Access The project team and its engineering, survey and environmental consultants will require access to private and public parcels to complete studies needed as part of the planning and design process for the project. The nature of each study is described in more detail below. 2. Geotechnical Explorations The Contractor shall perform subsurface explorations at or near the locations shown in the attached maps. Explorations shall include both soil borings and/or Cone Penetration Tests (CPT). Representative soil samples will be obtained from the borings at approximately 45- 100ft depth. All samples will be taken off site for further examination and geotechnical laboratory testing for analysis. There will be up to five people on-site to complete the borings: a driller, up to two driller's helpers, a logger, and a County grout inspector. The boring will be performed using a tire-mounted drill rig. In addition, there will be a support truck for the drill rig, a pick-up truck for the logger, and a pick-up truck/car for the grout inspector. After each boring is completed, the driller will place soil cuttings and drilling fluid in 55- gallon drums. The drums will be removed from the site on the day the boring is complete and disposed of at an appropriate disposal facility. The borings will be backfilled with neat cement grout in accordance with the County's well permit requirements. Boring performed in parking lots will be capped with asphalt to match the existing parking lot surface. All equipment, materials, and trash will be removed from the site and the area will be restored to its prior condition. 3. Biological Resource Surveys Various biological surveys would be conducted including, but not limited to, those described below. Wetland Delineation: Delineations would be conducted by qualified biologists. Activities would consist of walking the parcel, taking representative photographs, and looking for standing water, wet spots, or concentrations of wetland vegetation. If any of these features are found, the biologist would use a shovel to dig a test pit (2 feet by 2 feet to a depth of about 20 inches) in the center of the wetland feature to identify the soil properties and another outside the feature for comparison. The outline of the feature would be mapped using a Global Positioning System (GPS) receiver. The test pit
