accordance with the Section 106 PA, and based on findings included in the originally certified 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 (1SA1 Report - An ISA report will be prepared in accordance with Caltrans' SER, Volume 1, Chapter 10 (Hazazdous 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 1VI) 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 yeaz 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 aze 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 (DRIB and FRIS, respectively) will be prepazed pursuant to FHWA guidelines to comply with the Uniform Relocation Assistance and Real Property Acquisition Policies Act and policies set forth in Caltrans' Division ofRight-of--Way Procedural Handbook, Chapter 602. traffic Impact Analysis Traffic Impact Anal will be conducted and prepared to meet City and Caltrans' requirements. The analysis for this project will, to the extent possible, utilize information developed as part of the traffic analysis conducted as part of the originally certified EIR. The Traffic Impact Analysis will evaluate the project alternatives for consistency with the City's General Plan Circulation Element, City's Master Plan of Bikeways, Orange County Transportation Authority Master Plan of Arterial Street and Highways, and SCAG's Regional Comprehensive Plan and Regional Mobility Element. Project alternative impacts will also be evaluated with respect to on-street parking and during the construction of the street widening improvements. Initially, a field review will be conducted to document the existing features of the affected roadway segment and key study intersections within the limits of the project. URS also will review available traffic count data from the City to determine if any recent counts have been conducted within the study azea. New traffic counts will be collected as needed to supplement older or missing traffic data. It is assumed that all relevant and applicable cumulative projects will be identified and will be provided by City staff. Finally, URS will collect all applicable (approved) improvements at the study roadway segment and intersections that will by implemented within the traffic analysis scenarios (i.e., existing and future analyses). The traffic analysis will evaluate two key study intersections (i.e., Grand Avenue/Fourth Street, and Grand 11 25H-13
