3.2 Environmental Technical Studies
Air Quality and GHG Study
PlaceWorks (sub-consultant) will prepare an air quality and greenhouse gas (GHG) emissions analysis to evaluate impacts of the proposed roadway widening project. The analysis will be prepared in accordance with the current methodology of the South Coast Air Quality Management District (SCAQMD) for projects in the South Coast Air Basin (SoCAB). Emissions will be quantified using the latest version of SCAQMD’s California Emissions Estimator Model (CalEEMod). The results of the analysis will be summarized in the IS and modeling included as an appendix.

Construction and Operation Phases. The air quality and GHG emissions technical analysis will provide an estimate of the increase in short-term criteria air pollutant and GHG emissions generated from construction of the proposed project. Construction phase regional emissions will be based on the construction schedule, including duration for each construction subphase, anticipated equipment for each construction subphase, and estimated soil haul volumes (if applicable), as provided. Where information is unavailable, CalEEMod defaults will be utilized, as appropriate. The calculated project-related construction emissions will be compared to the SCAQMD regional significance thresholds for construction. Localized air pollution impacts from construction equipment exhaust and fugitive dust will also be compared to SCAQMD’s screening-level construction LSTs. If necessary, mitigation measures will be recommended to reduce impacts. Due to the linear nature of the project and the anticipated short duration for construction, a health risk analysis is not proposed. Because the proposed project would not generate new vehicle trips and would be accommodating existing vehicle trips already generated by surrounding land uses, operational impacts will be described qualitatively.

Other Areas of Impact. The SoCAB is currently designated nonattainment under the National and/or California ambient air quality standards (AAQS) for ozone (O3), fine inhalable particulate matter (PM2.5), and coarse inhalable particulate matter (PM10). To address this, the SCAQMD has adopted the 2016 Air Quality Management Plan (AQMP). The AQMP is prepared to ensure the SoCAB can attain the long-term National and California AAQS. The air quality analysis will include a consistency evaluation of the project’s regional emissions to SCAQMD’s AQMP. Furthermore, the SoCAB has been designated in attainment for carbon monoxide (CO) under both the California and National AAQS. Therefore, the air quality analysis will include only a qualitative assessment of CO hotspots. In addition, the initial study will also include a qualitative assessment of potential odor generation to describe potential odor impacts.

Project Consistency with Plans Adopted to Reduce GHG Emissions. The GHG section will discuss the GHG reduction goals of Senate Bill 32 (SB 32), SB 375, and Assembly Bill 1279 (AB 1279). To achieve the GHG reduction targets of SB 32, the California Air Resources Board (CARB) updated its Scoping Plan in 2022. In addition, the Southern California Association of Docusign Envelope ID: A24365C0-3F99-4170-8D11-C91BEF598D8E Docusign Envelope ID: E84300FD-307F-497B-8C43-20CBCD6CD450 CA\DD\02000.50105\10005846.1
10 (BB&K: 9-10)
27157.11000\2955190.2
Governments (SCAG) has adopted a regional transportation plan/sustainable communities strategy (2020-2045 RTP/SCS) to ensure that the southern California region can attain the regional transportation-related GHG reduction goals of SB 375. Project consistency with these statewide and regional GHG emissions reduction strategies will be reviewed.

Biological Resources Study
The Project site is located within the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) planning area. To determine whether sensitive biological resources are present on the Project site, a reconnaissance-level survey will be performed.

Prior to conducting the survey, a literature search will be conducted using public databases including California Department of Fish and Game’s (CDFW’s) California Natural Diversity Data Base (CNDDB), California Native Plant Society’s Electronic Rare Plant Inventory, range maps for special-status species, City of Corona’s Urban Forest Management Plan, and other documentation pertinent to the region. The search will identify the approximate locations of known or expected sensitive biological resources and habitats located within or near the Project site.

Once the literature search and analysis has been completed, ECORP (sub-consultant) will perform a field survey of the Project site. Although the Project site appears to be mostly developed there may be a potential biological issue associated with urban areas, such as nesting birds in ornamental trees. The field visit will consist of a brief site walkover to assess trees and biological resources that are present. Biological resources that are known to or potentially occur on the Project site will be searched for during the survey. Habitats and vegetation communities will be mapped. Representative photographs will be taken to document the site’s conditions at the time of the survey. A full list of plant and wildlife species will be recorded during the survey. If any sensitive biological resources are found within the Project site, its location will be recorded, and the resource will be discussed in the Biological Technical Report.

The Project site is subject to the requirements of the MSHCP; therefore, at a minimum, habitat assessments for riparian/riverine, vernal pool, and fairy shrimp (MSHCP Section 6.1.2), narrow endemic plant species (MSHCP Section 6.1.3), burrowing owl (MSHCP Section 6.3.2, and the urban/wildlands interface (MSHCP Section 6.1.4) would be required for compliance under the MSHCP. As a cost-saving measure, the biological reconnaissance survey and habitat assessments for the MSHCP resources, including burrowing owl, will be conducted concurrently. The burrowing owl habitat assessment will include a focused burrow survey which is considered Part A of the MSHCP focused protocol burrowing owl survey requirement.

The survey will consist of walking the entire site to identify suitable burrowing owl habitat and any suitable burrowing owl burrows. If burrowing owl habitat is present, an additional 500- foot buffer around the Project site will also be walked, if permissible. Where access is not permissible, the area will be visually inspected using binoculars and/or spotting scopes. The biological reconnaissance survey and burrowing owl habitat assessment will be conducted according to the protocols required by the MSHCP.

11 (BB&K: 9-10)
27157.11000\2955190.2
A Biological Technical Report will be prepared to document the methods and results of the literature search and biological reconnaissance survey. The report will include a summary of the biological setting of the Project site, a Project description, discussion of survey methods and results, a description of potential sensitive species occurring on the Project site, a brief discussion of the regulatory setting, and potential biological constraints to the proposed development. Lists of wildlife and plant species observed during the surveys will be included as an appendix. The report will conform to the information needs under the California Environmental Quality Act (CEQA). If necessary, recommendations for further work, including focused surveys for sensitive species or an aquatic resources delineation, will be discussed in the report. This scope of work does not include costs for focused (protocol-level) surveys or coordination with the regulatory agencies. If those services are determined to be necessary, the cost estimate for those services will be submitted under a separate cover. ECORP (subconsultant) will submit one electronic copy of the draft Biological Technical Report. After receiving one round of compiled comments, a final version of the report will be submitted electronically.

Noise Study
The evaluation of noise impacts associated with the Project will be completed by experienced staff members who are noise experts. The applicable noise criteria for the Project area will be reviewed and discussed as these standards will be the basis for the Project impact determination and whether mitigation is necessary. The analysis will be presented in a technical report and be supported by modeling documentation, which would be included as an attachment to the technical report.

Substantial construction noise would occur during implementation of the Proposed Project, potentially affecting the sensitive residential receptors in the area. Noise impacts from construction sources will be analyzed using the Federal Transit Administration Roadway Construction Noise Model and based on the anticipated equipment to be used. The construction noise impacts will be evaluated in terms of hourly equivalent continuous noise levels (Leq) and the frequency of occurrence at vicinity receptors. In addition to construction noise, an analysis of construction-related vibration impacts will be based on current California Department of Transportation criteria.

The Proposed Project would not be a permanent source of stationary source noise. While, the Project would not directly generate vehicle trips, a substantial source of noise in Corona, the proposed traffic facility improvements could change traffic patterns in Corona in a manner that increases traffic noise along Ontario Avenue above existing conditions. According to the 2013 Caltrans Technical Noise Supplement to the Traffic Noise Analysis Protocol, doubling of traffic on a roadway is required to increase noise to a perceptible level for humans. Potential noise impacts from vehicular traffic will be assessed based on the transportation analysis prepared for the Project.

27157.11000\2955190.2
Cultural
ECORP (sub-consultant) will conduct a cultural resources inventory of the proposed Project Area along West Ontario Avenue between Oak Avenue and South Vicenta Avenue, and South Lincoln Avenue from West Ontario Avenue to Othello Lane. The cultural resources inventory will be conducted under the direct supervision of a Registered Professional Archaeologist who meets the Secretary of the Interior’s Professional Qualifications Standards for prehistoric and historic archaeology. This study will be conducted pursuant to compliance with the California Environmental Quality Act (CEQA) and Section 106 of the National Historic Preservation Act.

The scope of work for the cultural resources inventory includes a records search of the California Historical Resources Information System (CHRIS) and literature review for the Project Area. ECORP (sub-consultant) will request a records search of the CHRIS from the Eastern Information Center (EIC). The CHRIS records search will identify the locations and extent of previous surveys conducted within 0.25 mile of the Project Area and will determine if there are any known cultural resources (i.e., pre-contact [prehistoric] or historic archaeological sites or historic-period features) located within or near the Project Area. In addition, the records search will identify resources listed on or determined eligible for listing on the National Register of Historic Places (NRHP) and/or the California Register of Historical Resources (CRHR) located within or near the Project Area. Note: the EIC response time is a minimum of 90 days.

ECORP (sub-consultant) will also request a search of the Sacred Lands File from the NAHC. The Sacred Lands File search will identify any known sensitive or sacred Native American resources located within or near the Project Area. It should be noted that the Sacred Lands File search will not constitute consultation in compliance with Senate Bill (SB) 18, Assembly Bill (AB) 52, or Section 106 of the National Historic Preservation Act (NHPA). SB 18, AB 52, and Section 106 consultation are separate processes from cultural resources technical studies and are not included in this scope of work.

ECORP (sub-consultant) will complete an intensive field survey of the Project Area using pedestrian transect intervals spaced 10 to 15 meters apart, where possible. An ECORP archaeologist will closely examine the Project Area for surface evidence of cultural materials, including pre-contact and historic-period (i.e., over 50 years of age) cultural deposits and features. If any resources are identified in the Project Area, they will be recorded and mapped in detail in accordance with the standards of the California Office of Historic Preservation (OHP).

Based on preliminary research, ECORP (sub-consultant) noted that all the primary roadways within the Project Area (West Ontario Avenue, Lincoln Avenue, Oak Avenue, and Buena Vista Avenue) are more than 50 years old as are the nine structures in the southeast corner of West Ontario Avenue and Lincoln Avenue. The City requested that only one structure directly at that intersection be evaluated for the NRHP and CRHR. Pursuant to compliance with CEQA and Section 106, a qualified ECORP (sub-consultant) architectural historian will record and Docusign Envelope ID: A24365C0-3F99-4170-8D11-C91BEF598D8E Docusign Envelope ID: E84300FD-307F-497B-8C43-20CBCD6CD450 CA\DD\02000.50105\10005846.1

evaluate this residential structure and all the roadways. The evaluation will include an architectural review of the residential structure. We assume there are no other resources within the Project Area.

ECORP (sub-consultant) will prepare a cultural resources inventory and evaluation report that documents the methods and results of the CHRIS records search, Sacred Lands File search, field survey, and evaluation of the one residential structure and the roadways. The report will also present recommendations for further work, if needed.

3.3 Administrative Draft CEQA Addendum
PlaceWorks (sub-consultant) will prepare an Initial Study (IS) and addendum using the City’s template that will include a discussion of the proposed project and detailed analysis of the following environmental areas:

Aesthetics
Agriculture and Forestry Resources
Air Quality
Biological Resources
Cultural Resources

The issues identified with an asterisk (*) will be scoped out of the initial study in the introductory text as unnecessary because of the type of project. The initial study will include detailed explanations of the remaining checklist determinations and discussions of potential environmental impacts. The analysis will be prepared in accordance with Sections 15063, 15070, and 15072 of the CEQA Guidelines.

A discussion of the existing environmental baseline conditions will be provided for each issue area. The IS will identify and evaluate: (1) potentially significant impacts; (2) potentially significant impacts unless mitigated; (3) less than significant impacts; and (4) issues resulting in no impacts. The IS will consider relevant direct, indirect, and cumulative impacts. Findings will be clearly substantiated for each checklist question to explain the basis for the environmental determination.

Except for the project-specific technical analyses, the analysis in the initial study will be based on available literature, including but not limited to the City’s General Plan EIR and Municipal Code; previously completed environmental documents; consultation with local public service and utility providers.

3.4 Final CEQA Addendum
Following City comment on the administrative initial study and addendum, PlaceWorks (subconsultant) will prepare a final version for attachment to the staff report for the Commission and Council for the general plan amendment. PlaceWorks (sub-consultant) can also help with the wording for the staff report for environmental compliance. In this context the Addendum is essentially a summary of the technical studies and initial study and is used to support the recommendation in the staff report for environmental compliance. This scope assumes that all documents are electronic and there are no printing costs. PlaceWorks(sub-consultant) will provide both Word files and PDF suitable for posting on the City’s website.

Notice of Determination
PlaceWorks (sub-consultant) will prepare a Notice of Determination (NOD) for the project, based on the findings of the Initial Study/Mitigated Negative Declaration. PlaceWorks (subconsultant) assumes the City will file the NOD with the County Clerk within 5 days of project approval and adoption of the MND and pay all filing fees.
