EIR, it is anticipated that all affected structures can be exempted from further evaluation and that a Historic Resources Evaluation Report will not be required. Initial Site Assessment (ISA) Report - An ISA report will be prepared in accordance with Caltrans' SER, Volume 1, Chapter 10 (Hazardous Waste) to confirm potentially hazardous material and waste impacts and any need for further assessment/remediation. This scope of work does not include any investigation or reporting beyond that required as part of the ISA report. It could be that demolition of the affected structures/buildings require further follow-up investigation (e.g., asbestos, lead-based paint, etc.). If required, URS could perform such follow- up investigations under an amendment to the contract. Noise Study Report - The proposed project is a "Type I" project as defined by 23 CFR 772 because it will add through lanes of travel. Therefore, noise impacts, and the potential need for noise abatement (e.g., soundwalls) would be assessed in accordance with guidelines set forth in Caltrans' Traffic Noise Analysis Protocol (2006) and Technical Noise Supplement (1998). URS will conduct a field noise study to quantify and assess existing noise conditions at the potential noise-sensitive areas. It is estimated that sound level data will be collected at up to eight selected locations throughout the day. In addition, continuous 24-hour noise monitoring will be conducted at up to three locations in the project area if secure measurement locations can be identified. URS will conduct traffic noise modeling related to the proposed project using the FHWA Traffic Noise Model (I Iv 1 VI) Version 2.5 and traffic data to be provided by the project traffic engineer. TNM will be used to model highest noise hour conditions at representative modeled receiver locations under existing conditions and design year conditions with and without the proposed project. Traffic noise impacts of the proposed project under 23 CFR 772 will be assessed by determining if implementation of the project is projected to result in traffic noise levels under design year conditions that approach or exceed the FHWA noise abatement criteria or if implementation of the project is predicted to result in a substantial increase in noise at noise- sensitive uses. If traffic noise impacts are projected to occur, information on the preliminary feasibility and reasonableness of noise abatement as defined in the Protocol will be evaluated and presented for use by decision makers in considering noise abatement. URS will also evaluate potential construction noise impacts using methods recommended by the U.S. Department of Transportation. Relocation Impact Study - It is expected that Draft and Final Relocation Impact Study (DRIS and FRIS, respectively) will be prepared pursuant to FHWA guidelines to comply with the Uniform Relocation Assistance and Real Property Acquisition Policies Act and policies set forth in Caltrans' Division of Right-of-Way Procedural Handbook, Chapter 602. 12
