Proposal for Santa Ana Main Street Corridor Improvements Z. - Task Task 3: Geotechnical Study Infiltration Test and Soil Suitability: Our team will conduct a geotechnical field review as follows: Percolation rate test at four locations within the proposed bulb -out areas; and Agronomy/soil fertility laboratory testing encompassing major element fertility package, agricultural suitability package, and USDA particle size analysis We will compile data and geotechnical analysis of the field and laboratory tests consisting of analyses to evaluate and provide recommendations pertaining to the following: Percolation rate characteristics of the soils, Atterberg Limits/Plasticity Index, moisture and density, suitability of the on-site soils for landscape improvements, foundation design criteria for new monuments or signs We will prepare a report presenting the results of field exploration, geotechnical laboratory testing, engineering analyses, conclusions and recommendations relative to the project. Pavement Evaluation: We will provide the following services: • Subsurface exploration consisting of the excavation, sampling, and logging of eight hand excavated cores to depths of approximately 3 feet or refusal within the project limits. The purpose of the pavement borings will be to observe the existing structural pavement sections and collect soil samples for geotechnical laboratory testing. Our team will compile data and geotechnical analysis of the field and laboratory tests with analyses to evaluate and provide recommendations pertaining to the following: • Evaluate the R -value and in-place moisture content of subsurface soils. • Excavation and compaction requirements, including suitability of the on-site soils for subgrade material for the proposed improvements. • Analysis and design of new pavement construction and pavement rehabilitation alternatives within the proposed bike path areas. The analysis will be performed in general accordance with the Caltrans Highway Design Manual design method. We assume that the 10- and 20 -year design traffic indices (TI) for the subject streets will be provided to us by the City for our analyses. Deliverables: Draft Pavement and Soil Material Report, Final Pavement Report and Soil Material Report Task 4: Record Research and Utility Coordination Kimley-Horn will obtain readily available record drawings and data pertinent to the scope of services such as record drawings, GIS mapping, and utility atlases. We will initiate the utility company notification process early in the design process and identify potential conflicts. We will maintain a utility agency tracking list to indicate the status of communication and add a contact list for substructure and utility owner -operators for the specifications. We will assist the City with a utility notification letter consisting of the following: 1. Utility Information Request 2. Prepare to Relocate Notice/Final Utility Notice Form 3. Notice to Relocate Kimley»)Horn 12 TR8077004.17I City of Santa Ana
