Exhibit A-2 Santa Ana Boulevard Grade Separation Project Scope of Services for Completion of the Project Approval/Environmental Document Phase Description of Project The development and construction of this project is being undertaken by the City of Santa Ana (City), who will also be serving as the project's administrator for the preliminary studies, environmental documentation, design, right-of-way engineering, right-of-way acquisition, and construction. The selection of the preferred alignment for the Santa Ana Boulevard Grade Separation will require the approval of the City and SCRRA/OCTA. The selection of the locally preferred alternative, early in the project development process, is critical in maintaining the schedule for the project's completion. As stakeholders in the project, local community and business owner acceptance of the recommended alignment is a prerequisite for City approval and a successful project. The proposed project will construct a Grade Separation at the crossing of Santa Ana Boulevard, with the SCRRA/OCTA Metrolink line (Metrolink). Phase 1 of the Project is Preliminary Engineering, requiring an investigation as to the most cost-effective alternative for separating the grades, beginning with a simplified Project Study Report Equivalent (PSRE), and culminating in a Project Report Equivalent (PRE), a recommendation; and submitting a Notice of Exemption (Statutory Exemption) as a part of the California Environmental Quality Act (CEQA). Phase 1 concludes with the acquisition of right of way. Phase 2 of the Project development will require final design: plans, specifications and cost estimates for the construction of project; and relocation of utilities. We shall submit a CD to the City, which will include all surveying, environmental reports, technical studies, the PSRE, the PRE, the design files, both plans and specifications, and any supporting documents produced during the course of the project development. This scope of services is written for Phase 1 only. Description of Work General Description of Required Services Phase 1 - Preliminary Engineering, PSRE, and PRE AECOM shall provide professional and technical engineering services necessary to investigate alignment alternatives, prepare a PSRE, documenting potential solutions to the project's purpose and need; a PRE, recommending an alternative; and providing the necessary documentation to obtain environmental clearance. Work will include, but not necessarily be limited to, preliminary engineering, field surveys, obtaining SCRRA/OCTA design requirements, traffic studies, geometric layouts, preliminary right-of-way layouts, and order of magnitude cost estimates. AECOM shall assist the City in any public meetings, City Council presentations, and meetings with area business owners. The work in Phase I is more fully described later within this Scope of Services. Proposed Project The proposed project is to grade separate Santa Ana Boulevard at the Metrolink at-grade crossing. Highway Alignments The roadway width, and subsequent right of way width, will be determined based upon the City's General Plan for Santa Ana Boulevard, as reinforced by the projected traffic volumes generated by our traffic studies, as described later within this scope, and the number of lanes required for the year 2035 to provide a minimum Level of Service required by the City. The vertical alignment of the road will be designed to conform to sight distance and safety standards. Cily of Santa Ana 25B-20
