The URS Acoustics and Noise Control Group staff will assess the existing land uses on and surrounding the project i site using the most recent land use mapping provided by the City for the proposed project. Should noise mitigation measures be required for either short-term or long-term project related impacts, a series of specific noise mitigation measures will be developed (including types, locations, sizes, materials) which will reduce the impact of project related noise levels to meet the applicable exterior noise standards at the surrounding noise sensitive land uses. A Noise P Technical Report will be prepared documenting the results of the noise measurement survey, detailing the findings of P impact, the mitigation measures necessary to reduce those impacts, and level of significance. Federal Aviation Administration (FAA) / Airport Land Use Commission (ALUC) i URS has successfully prepared many documents for FAA NEPA projects and FAA Part 150 Noise Land Use Compatibility Studies throughout the nation, including for Los Angeles International Airport, Portland International / Airport, Salt Lake City International Airport, and Orlando International Airport among others. Locally, URS t personnel are very familiar with the California Aeronautics Act and the John Wayne Airport Phase 2 Commercial Airline Access Plan and Regulation which places restrictions on operational capacity, hours of operations, and noise levels on aircraft operating from the facility. URS team members have previously worked with ALUC staff, and therefore are very familiar with the noise contour development process, land uses in the environs of the airport, and the varied, often competing interests of the surrounding cities. 1 Air Quality URS offers complete air quality services, including meteorological and air quality monitoring, air pollutant emissions calculations, and atmospheric dispersion modeling in support of our environmental planning and compliance services. ' We have well -established, positive working relationships with SCAQMD staff. URS adapts and uses a large number of Gaussian dispersion models, including all of the models in the U.S. Environmental Protection Agency, UNAMAP series. Our capabilities include source type models as well as transport models, ranging in complexity from simple screening models to complex three-dimensional grid models useful for analyzing inert and reactive pollutant concentrations in regions of complex airflow. Cultural Resources URS understands that effective cultural resource management is an essential element of the community preservation agenda for the City of Santa Ana. URS' extensive experience in the evaluation of cultural resources (pre -historic and historic) for environmental assessments is performed in compliance with the CEQA, NEPA, and federal and state historic preservation requirements (e.g., Section 106 of the National Historic Preservation Act, among others). Our cultural resources services include field inventories, National Register of Historic Places eligibility evaluations, SHPO/Section 106 processing, and ethnology/Native American coordination. Our depth will allow us to interact with staff, community leaders, and the Historic Resources Commission on key localized issues. Water Quality Study/Assessment URS has been involved in all major aspects of the ongoing effort to assess and effectively control point and non -point sources of water pollution including / ➢ Monitoring for wastewater and storm water discharges; ➢ Pollutant source characterization and transport studies; ➢ National (Pollutant Discharge Elimination System (NPDES) permitting and stormwater management for industries, municipalities and construction sites; ➢ Best Management Practice selection and implementation; ➢ TMDL modeling, development and analysis; and ' ➢ Interpretation of CWA regulations and permit negotiations with RWQCBs. 14
