Environmental Task 1- Preliminary Environmental Study (PES) Prepare the PES form in accordance with the Local Assistance Procedures Manual (LAPM). The PES form will be used to consult with Caltrans/FHWA to determine the appropriate NEPA document for the project (in this case, a CE). The LAPM requires the following steps for this process: ■ Step 1: Develop Complete Project Description and Detailed Map. Prepare a description of the project including the location of the project area (including a project map); a brief description of the environmental setting; and identification of environmental effects using the PES. ■ Step 2: Review Relevant Literature, Maps, and Inventories. Review existing environmental and planning information, such as the City's General Plan and General Plan EIR, soil surveys, and the California Natural Diversity Database (CNDDB) and California Native Plant Society Electronic Inventory (CNPSEI). We have also assumed that technical studies prepared for this project will be provided to us for use in the PES, as applicable. ■ Step 3: Request Technical Information from Resource and Regulatory Agencies. This step will be completed concurrently with Step 2. ■ Step 4: Verify Research Findings in the Field (Site Visit). A site visit will be conducted by an Environmental Scientist. ■ Step 5: Complete PES Form. Complete the PES form and provide an electronic copy to the City for internal review. We will revise the PES based on comments from the City prior to submittal to Caltrans. We will complete the PES form and provide an electronic copy to the City for internal review and revise based on comments from the City prior to submittal to Caltrans. It is assumed that since impacts would be minimal, detailed technical studies would not be required and the project would qualify as a Screened Undertaking for cultural resources under Section 106 of the National Historic Preservation Act. Screened undertakings are classes of projects that have the potential to affect historic properties, but may be determined exempt from review under the Section 106 Programmatic Agreement. Exempt classes include (but are not limited to): 1. Minor widening of less than one -half -lane width, adding lanes in the median, or adding paved shoulders. 2. Channelization of intersections or addition of auxiliary lanes. 3. Minor utility installation or relocation. 4. Addition of bicycle lanes or pedestrian walkways. 5. Modification of existing features, such as slopes, ditches, curbs, sidewalks, driveways, dikes, or headwalls, within or adjacent to the right-of-way. Task 2 - NEPA Categorical Exclusion and CEQA Categorical Exemption NEPA Categorical Exclusion Prepare a Draft CE checklist form in the most recent Caltrans format included in Caltrans' Standard Environmental Reference (SER), Chapter 30 - Categorical Exclusions. The Draft CE Checklist will be provided to the City for review. We will make any revisions to the CE Checklist and provide a Revised Draft CE Checklist to the City for submittal to Caltrans. After Caltrans review, we will revise the document and provide the Final document to:thc City for submittal to Caltrans. This scope of work and cost estimate assumes one round of comments and responses for each version of the document (Draft and Revised Draft) and that no additional analysis or technical studies are required to respond to comments. CEQA Categorical Exemption After an initial review, it appears that the proposed project is likely exempt from CEQA under Class 1: minor alteration of existing facilities (CEQA Guidelines Section 15301) or Class 2: replacement or reconstruction (CEQA Guidelines Section 15302). Our subconsultant will prepare the Exemption Form from Appendix E of the CEQA Guidelines. This form will be filed at the County Clerk's office and the State Clearinghouse. A receipt of fling will be obtained from both entities. PHASE 2: CONSTRUCTION DOCUMENTS (PS&E) Plans and cost estimates will be prepared and submitted to the City for review at the 60 and 100 (final) percent levels. Based on feedback from the review from City staff during the preliminary design phase, detailed construction plans will be prepared. Sheets for the street improvements include title sheet, typical section/detail sheet, street plan and profile, signing and striping, and landscape/irrigation. All plans will be prepared in AutoCAD, Digital files and one set of original mylars shall be provided to the City upon final approval. Special provisions will be prepared based on the Standard Specifications for Public Works Construction and the City's boilerplate, supplemented with Caltrans specifications. All submittals will be in Microsoft Word format. Preliminary cost estimates will be prepared for the proposed improvements and included with the first plan check submittal. Final construction cost estimates will be prepared based on the final improvement plans. Street Improvement Plans Twenty -scale street improvement plans will be prepared using the topographic survey data and record utility information for the base sheets. Appropriatejoins will be provided at all side streets, driveways and intersections. Street improvements will show the rehabilitation of the existing pavement and the widening of the existing roadway. The use of cross -sections will be critical to /\/ ARDURRA City of Santa Ana I March 14, 2023 On -Call Engineering Services, RFP No. 23-030
