600 RIVERSIDE RD Geotech Report 2022-10-25

Landau Associates • Coordinating environmental and geotechnical services and providing consultation to the ' project team as the designs of the proposed projects progress. • Reviewing the 30 percent plans for roads and utilities developed by others as well as existing environmental data for the site in order to identify the need to incorporate approaches into the project design that address the potential of encountering contaminated soil and groundwater during construction. • • Preparing a soil and groundwater management plan for the project. Reviewing readily available geologic, geotechnical, and topographic information for the project area. 0 Developing an exploration plan. • Arranging for underground utility location prior to performing field activities. 1 • Arranging for a private utility locating company to check for the presence of subsurface utilities prior to performing field activities. • Advancing a series of exploratory test pits and exploratory borings to characterize soil and groundwater conditions at the project site. • Collecting representative soil samples at selected depth intervals. • Logging the explorations and recording pertinent information, including soil sample depths, stratigraphy, soil engineering characteristics, and groundwater occurrence. • Conducting a geotechnical laboratory testing program. • Performing geotechnical engineering analyses and evaluating data derived from the subsurface investigation and laboratory testing program. ' • Developing geotechnical engineering conclusions and recommendations to support design and construction of the proposed improvements. • Preparing and submitting this written report summarizing our findings, conclusions, and recommendations for the project. This report includes: — a site plan showing the locations of current and previous subsurface explorations and other pertinent site features — logs of the current and previous relevant explorations — an evaluation of the feasibility of the proposed construction with respect to ' geotechnical and environmental issues — a summary of subsurface soil and groundwater conditions anticipated in the vicinity of the proposed improvements — a summary of potential soil and groundwater contamination conditions across the site — recommendations regarding anticipated excavated soil handling and disposal requirements — recommendations regarding anticipated health and safety construction requirements related to contaminated soil and groundwater Geotechnical Engineering Report 0121030.010.011 Riverside Business Park March 22, 2018 Public Access Trails and Roadway improvements 1-2
