EXHIBIT 2 <br /> Santa Ana Blvd. Grade Separation <br /> Table 4 - Cost Breakdown <br /> Construction Cost $45.OM <br /> Roadway $32.9M <br /> Structures $12.1 M <br /> Right-of-Way $15.6M <br /> Total Project Capital Outlay $60.6M <br /> Support (PS&E, Right-of-Way, Construction, $12.7M <br /> Program Management) <br /> Total Project Cost $73.3M <br /> 6 ENVIRONMENTAL DETERMINATION <br /> Caltrans is the National Environmental Policy Act (NEPA) Lead Agency for this project. Initially, <br /> Caltrans determined that the appropriate environmental documentation for NEPA compliance is <br /> an Environmental Assessment (EA). Refer to Attachment J for the Preliminary Environment <br /> Study (PES). However, upon the completion of the required technical studies and public meeting, <br /> it was determined that the project is Categorically Excluded (CE). The Categorical Exemption / <br /> Categorical Exclusion Determination Form is included as Attachment K. The project is also <br /> Statutorily Exempt (SE) from the California Environmental Quality Act (CEQA) per Section <br /> 15282(g). City has filed the Notice of Exemption (NOE) as the lead agency on June 23, 2014. <br /> The PES recommended the following technical studies to support these documents: Traffic Study; <br /> Noise Study Report; Air Quality Assessment Report; Initial Site Assessment; Water Quality <br /> Memorandum; Natural Environmental Study-Minimum Impact; Visual Impact Assessment; <br /> Relocation Impact Memorandum; Historical Property Survey Report; Archaeological Survey <br /> Report, Historic Resources Evaluation Report, and Community Impact Assessment. The <br /> Environmental Commitment Record listing various mitigation measures is included as Attachment <br /> L. The result of the Traffic Study is included in Section 4.5 and the results of the remaining studies <br /> are included as follows: <br /> 6.1 Noise Study Report (NSR): <br /> The NSR determined that six of the 16 modeled receivers (representative of six residences <br /> or noise-sensitive receptors) would approach or exceed the FHWA/Caltrans noise <br /> abatement criteria (NAC)for Activity Category B and C land uses with the implementation of <br /> the project. Noise abatement in the form of soundwalls was considered. Two soundwalls <br /> were found to be acoustically feasible and the estimated cost to construct was compared <br /> with the reasonable allowance. NB-2 was determined to be reasonable to construct at <br /> heights of 12 to 16 feet. <br /> During construction of the proposed project, noise from construction activities would <br /> intermittently dominate the noise environment in the immediate area of construction. <br /> Conventional construction equipment is expected to generate maximum noise levels ranging <br /> from 75 to 99 decibels (dB) at a distance of 50 feet, while noise from pile driving, if <br /> necessary, would generate maximum noise levels of approximately 101 dB at a distance of <br /> 50 feet. Noise produced by construction equipment would diminish over distance at a rate of <br /> about 6 dB per doubling of distance. No adverse noise impacts from construction are <br /> anticipated because construction would be conducted in accordance with the Department's <br /> PROJECT REPORT EQUIVALENT 13 <br />
