<br />Scope of Services for Completion of the
<br />Project Approval /Environmental Document Phase
<br />Descr otion of Projecf
<br />The development and construction of this project is
<br />being undertaken by the City of Santa Ana (City), who
<br />will also be serving as the project's administrator for the
<br />preliminary studies, environmental documentation,
<br />design, right -of -way engineering, right -of -way
<br />acquisition, and construction.
<br />The selection of the preferred alignment for the Santa
<br />Ana Boulevard Grade Separation will require the
<br />approval of the City and SCRRA /OCTA. The selection of
<br />the locally preferred alternative, early in the project
<br />development process, is critical in maintaining the
<br />schedule for the project's completion. As stakeholders
<br />in the project, local community and business owner
<br />acceptance of the recommended alignment is a
<br />prerequisite for City approval and a successful project.
<br />The proposed project will construct a Grade Separation
<br />at the crossing of Santa Ana Boulevard, with the
<br />SCRRA /OCTA Metrolink line (Metrolink). Phase 1 of the
<br />Project is Preliminary Engineering, requiring an
<br />investigation as to the most cost - effective alternative
<br />for separating the grades, beginning with a simplified
<br />Project Study Report Equivalent (PSRE), and
<br />culminating in a Project Report Equivalent (PRE), a
<br />recommendation; and submitting a Notice of Exemption
<br />(Statutory Exemption) as a part of the California
<br />Environmental Quality Act (CEQA). Phase 1 concludes
<br />with the approval of the PA /ED. Phase 2 of the Project
<br />development will require right -of -way acquisition, final
<br />design: plans, specifications and cost estimates for the
<br />construction of project; and relocation of utilities. We
<br />shall submit a CD to the City, which will include all
<br />surveying, environmental reports, technical studies, the
<br />PSRE, the PRE, the design files, both plans and
<br />specifications, and any supporting documents produced
<br />during the course of the project development. This
<br />scope of services is written for Phase 1 only.
<br />Description of Work
<br />AECOM shall provide professional and technical
<br />engineering services necessary to investigate alignment
<br />alternatives, prepare a PSRE, documenting potential
<br />solutions to the project's purpose and need; a PRE,
<br />recommending an alternative; and providing the
<br />necessary documentation to obtain environmental
<br />clearance. Work will include, but not necessarily be
<br />limited to, preliminary engineering, field surveys,
<br />obtaining SCRRA /OCTA design requirements, traffic
<br />studies, geometric layouts, preliminary right -of -way
<br />layouts, and order of magnitude cost estimates. AECOM
<br />shall assist the City in any public meetings, City Council
<br />presentations, and meetings with area business
<br />owners. The work in Phase 1 is more fully described
<br />later within this Scope of Services.
<br />Proposed Proj
<br />The proposed project is to grade separate Santa Ana
<br />Boulevard at the Metrolink at -grade crossing.
<br />The roadway width, and subsequent right of way width,
<br />will be determined based upon the City's General Plan
<br />for Santa Ana Boulevard, as reinforced by the projected
<br />traffic volumes generated by our traffic studies, as
<br />described later within this scope, and the number of
<br />lanes required for the year 2035 (or 2040) to provide a
<br />minimum Level of Service required by the City.
<br />The vertical alignment of the road will be designed to
<br />conform to sight distance and safety standards.
<br />Structural Improvements
<br />The proposed Santa Ana Boulevard Grade Separation,
<br />and the associated retaining walls, shall be studied to
<br />determine the most cost effective and efficient
<br />structural type, and this will include both pre -cast
<br />concrete and steel through plate girder alternatives. The
<br />crossing will also be studied in terms of providing an
<br />aesthetic bridge structure consistent with the
<br />surrounding community.
<br />An- o iceblbe St ndard
<br />The PSRE shall be prepared similar to CALTRANS'
<br />regulations, policies, procedures, manuals and
<br />standards. The following items a. through d. are not all -
<br />inclusive but are intended only to illustrate types of
<br />sources.
<br />a. The PSRE will be prepared similar to Caltrans'
<br />Project Development Procedures Manual
<br />Appendix L - Preparation Guidelines for Project
<br />Study Report.
<br />b. Roadway design shall be in general
<br />conformance with the current CALTRANS
<br />Highway Design Manual, Standard Plans and
<br />Specifications in English Units.
<br />c. Plans and estimates shall be prepared in
<br />general conformance with the current editions
<br />of the CALTRANS Plans, Specifications and
<br />Estimates Guide, Standard Plans and Standard
<br />Specification, and Basic Engineering
<br />Estimating System or as required by the City.
<br />d. This PSRE shall be performed in accordance
<br />with CALTRANS and AASHTO standards and
<br />practices. Any exceptions to applicable design
<br />standards shall be approved by the City via the
<br />process outlined in CALTRANS' Highway Design
<br />Manual and appropriate memorandums and
<br />design bulletins published by CALTRANS.
