Previous Adopted MND Finding – Less Than Significant Impact: The previous MND determined that the project would not result in the exposure of sensitive receptors to pollutants. The nearest sensitive receptors near the project site include multiple family residential uses located approximately 460 feet southeast, 570 feet south, and 781 feet west; a mobile home park located approximately 327 feet southwest and 315 feet north; a high school located approximately 327 feet southeast, and a transient lodging use (motel) located approximately 645 feet west of the project site. Per the air quality analysis, none of the analyzed criteria pollutants would exceed the local emissions thresholds at the nearest sensitive receptors. Therefore, a less than significant impact would occur and no mitigation was warranted.

Addendum Finding – Less Than Significant Impact: The proposed Modified Project would not expose sensitive receptors to pollutants because the Modified Project would be subject to the same rules and regulations established by the SCAQMD during the construction phase of the project. Also, the Modified Project’s pollutant emissions would not exceed the established regional pollutant emissions thresholds during the construction and operational phase of the Modified Project, as shown in Tables 5-A and 5-B. Therefore, impacts would be less than signific e.

Previous Adopted MND Finding – No Impact: The previous MND determined that the project’s short-term (construction) and long-term (operational) activities would result in no odor impacts.

Addendum Finding – Less Than Significant Impact: The Modified Project does not contain land uses typically associated with emitting objectionable odors. Potential odor sources associated with the proposed Project may result from construction equipment exhaust and the application of asphalt and architectural coatings during construction activities and the temporary storage of typical solid waste (refuse) associated with the proposed Modified Project’s (long-term operational) uses. Standard construction requirements would minimize odor impacts from construction. The construction odor emissions would be temporary, short-term, and intermittent in nature and would cease upon completion of the respective phase of construction and is thus considered less than significant. It is expected that Modified Project-generated refuse would be stored in covered containers and removed at regular intervals in compliance with the solid waste regulations. The proposed Project would also be required to comply with SCAQMD Rule 402 to prevent occurrences of public nuisances. Therefore, odors associated with the proposed Project construction and operations would be less than significant and no mitigation is required.

Discussion:

The following discussions contain information on the original traffic study that was prepared for the original project to provide background information and context for the Modified Project. An updated analysis was prepared for the Modified Project which is also discussed in this section.

Original Project Traffic Impact Analysis
A Traffic Impact Analysis (TIA) was prepared for the original project by Trames Solutions, Inc. (dated July 28, 2023, revised March 18, 2024) to evaluate the traffic impacts of the original project. Figure 5 shows the study areas that were included in the TIA. The study areas included the following:

1. Lincoln Avenue / Pomona Road

2. Lincoln Avenue / SR-91 Westbound On & Off Ramps

3. Lincoln Avenue / D Street – 2
nd Street

4. Lincoln Avenue / 6th Street

5. SR-91 Eastbound On & Off Ramps / 2nd Street

6. Buena Vista Avenue / 2nd Street

7. Cardena Driveway – Project Driveway #1 / 2nd Street

8. Project Driveway #2 / 2nd Street
In addition, three freeway segments on the SR-91 eastbound and westbound lanes:

1. SR-91 Westbound, east of Lincoln Avenue

2. SR-91 Westbound, between Ramps

3. SR-91 Westbound, west of Lincoln Avenue

4. SR-91 Eastbound, west of Lincoln Avenue

5. SR-91 Eastbound, between Ramps

Figure 4 shows the site plan for the Project. Project Driveway #1 is the west driveway and is restricted to right-in and right-out turn movements due to a required raised median that will be constructed in 2nd Street in front of the project frontage. Project Driveway #2 is the east driveway and will allow for full-turn movements.

Project Traffic Generation: The original project is anticipated to generate approximately 2,077 total average daily trips, with 127 trips during the AM peak hour and 145 trips during the PM peak hour. Table 6-A summarizes the original project’s trip generation.

Table 6-A: Project Trip Generation Summary
Cumulative Trip Generation (Project Plus Planned Developments): Other recently approved projects or projects that are pending approval by the City that are located in the vicinity of the project site were also analyzed with the Project to determine a cumulative generation of vehicle trips. The cumulative developments are projected to generate a total of approximately 7,984 trips per day with 712 trips during the AM peak hour and 903 trips during the PM peak hour. Table 6-B show the cumulative trip generation results.

Table 6-B: Cumulative Trip Generation Summary

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 22 Environmental Checklist

Existing Traffic Conditions For Study Areas: The City of Corona considers a Level of Service (LOS) D or above as acceptable. All study intersections are currently operating at a Level of Service (LOS) C or above in the AM and PM peak hours. The study freeway ramps are operating at an acceptable LOS D or better during the peak hours. The TIA also analyzed three freeway segments on the SR-91 eastbound and westbound lanes. All study freeway segments are operating at an acceptable LOS D or above.

Existing Traffic Conditions Plus Project Traffic: The existing traffic conditions for the study intersections plus the original project traffic are anticipated to operate at an acceptable LOS D or above during the peak hours. The existing traffic conditions for the study freeway ramps plus the original project traffic are anticipated to operate at an acceptable LOS D or above during the peak hours. The study freeway segments plus the original project traffic are anticipated to operate at an acceptable LOS Dor above during the peak hours.

Existing Traffic Conditions Plus Ambient Growth And Project Traffic: A 2% ambient growth rate was used in the TIA to account for traffic not attributed to the original project or other planned developments within the study area. With the ambient growth rate factored into the analysis, all study intersections, freeway ramps and freeway segments plus the original project traffic are anticipated to generate an LOS D or above during the AM and PM peak hours.

Existing Traffic Conditions Plus Ambient Growth, Project Traffic, And Cumulative Traffic: The existing traffic conditions for the study intersections plus ambient growth, original project traffic and cumulative traffic are anticipated to operate at an acceptable LOS D or above during the peak hours. The existing traffic conditions for the study freeway ramps plus original project traffic and cumulative traffic are anticipated to operate at an acceptable LOS D or above during the peak hours. The study freeway segments plus original project traffic and cumulative traffic are anticipated to operate at an acceptable LOS Dor above during the peak hours.

No Project Condition At Buildout (2040): Under the 2040 No Project Condition, the study intersections, freeway ramps and freeway segments are projected to operate at an acceptable LOS D or above. 2040 With Original Project Traffic Condition At Buildout (2040): Under the 2040 With Project Traffic Condition, the study intersections, freeway ramps and freeway segments plus the Project traffic are projected to operate at an acceptable LOS D or above.

For 2040 With Original Project Conditions, the intersection at Project Driveway #2 and 2nd Street is projected to meet traffic signal warrants. However, due to intersection spacing considerations, the TIA recommends that this intersection be stop signed controlled since it is anticipated to operate at an acceptable LOS D or above as a cross-street stop-controlled intersection. Additional discussions regarding this recommendation and other circulation and vehicular stacking recommendations are provided in Section 6f.

Modified Project Traffic Impact Analysis
A supplemental Corona C-Store Trip Generation/Pedestrian Access Evaluation was prepared by Trames Solutions (dated September 5, 2024) to evaluate the Modified Project. The proposed Modified Project with the carwash and fewer fueling positions would generate 413 fewer trips per day, with 67 fewer trips in the AM peak hour and 14 fewer trips in the PM peak hour.

Trames Solutions also evaluated three potential crosswalk locations on 2nd Street to provide pedestrian access to the project site. These included the following:
• Option 1 – Sidewalk to Buena Vista Avenue
• Option 2 – Mid-Block Crossing on 2nd Street
• Option 3 (original option) – 2
nd Street/SR-91
Under Option 1, a sidewalk would be constructed between the project site and Buena Vista Avenue to the east. This would allow pedestrians to use the existing crosswalk at the existing stop-controlled intersection at 2nd Street/Buena Vista Avenue and access the project site on the north side of 2nd Street. Trames Solutions recommended this solution as it would allow for a safer crossing of 2nd Street for pedestrians to access the site because vehicles would be stopped at the intersection to allow pedestrians to cross the street.

Under Option 2, an uncontrolled painted/lighted crosswalk on 2nd Street between the project site and Buena Vista Avenue would be installed to allow pedestrians to cross 2nd Street in an uncontrolled, marked crosswalk. Trames Solutions did not recommend this option because it would provide a false sense of security for pedestrians to believe that an oncoming vehicle

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 23 Environmental Checklist

will stop. The distance between the SR-91 on/off ramp and Buena Vista Avenue is about 1,100 feet. Since the crossing would be located between these two intersections, the relatively short distance to either intersection may not allow appropriate time for pedestrians to cross. Furthermore, a horizontal curve along 2nd Street exists in the vicinity of the crossing area and could reduce the visibility of drivers to pedestrians.

Option 3 was originally required by the city for the original project and evaluated in the prior MND. The applicant is in discussions with Caltrans to determine the feasibility of having this crosswalk in their facility. This crosswalk remains as a condition of approval with Option 1 as an alternative location for pedestrians to access the site.

Table 6-C: Project Trip Generation Summary
a.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not conflict with programs, plans, or ordinances that support transit services, bicycle lanes, sidewalks, and trails, because the required street improvements for 2nd Street associated with the original project would be designed in accordance with all applicable engineering standards relating to vehicle traffic, bicycles, pedestrian safety, line of site, and other design criteria. Furthermore, the Project is not proposing any improvements that would conflict with the existing public transit service lines in the immediate vicinity or any future transit route in the area. Therefore, the original project would not conflict with programs, plans or ordinances that support the City’s transit services.

Addendum Finding – No Impact: A Corona C-Store Trip Generation/Pedestrian Access Evaluation was prepared by Trames Solutions (dated September 5, 2024) to evaluate the revisions made the project (i.e., Modified Project). The Modified Project would be subject to the same roadway improvements on 2nd Street that were originally required for the original project.

Therefore, the level of impact would remain the same as previously identified in the adopted MND. Therefore, no additional mitigation is required.
b.

Previous Adopted MND Finding – No Impact: Senate Bill (SB) 743 was signed by Governor Brown in 2013 and required the Governor’s Office of Planning and Research (OPR) to amend the CEQA Guidelines to provide an alternative to LOS for evaluating transportation impacts. SB 743 specified that the new criteria should promote the reduction of GHG emissions, the development of multimodal transportation networks and a diversity of land uses. In response, Section 15064.3 was added to the CEQA Guidelines that became effective on July 1, 2020, and requires that Vehicle Miles Traveled (VMT) be evaluated for impacts and provides lead agencies with the discretion to choose the most appropriate methodology and thresholds for its evaluation.

The City of Corona Vehicle Miles Traveled (VMT) Analysis Guidelines lists screening thresholds to determine if land use projects would require a VMT assessment. The City’s Guidelines also provide criteria for projects that could screen out of further analysis and would be considered to have a less-than significant impact on VMT. If a Project meets one of the criteria

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 24 Environmental Checklist

below, it is considered to have a less than significant impact on VMT and does not require further analysis.

1. The Project serves the local community.

2. The Project is located within a Transit Priority Area (TPA).

3. The Project is located in a low VMT generating VMT generating model traffic analysis zones (TAZs).

Based on the Governor’s Office of Planning and Research (OPR) Technical Advisory on Evaluating Transportation Impacts in CEQA (OPR, December 2018), Screening Criteria 1 includes a local serving retail projects of up to 50,000; Screening Criteria 2 is defined as a ½ mile radius around an existing or planned major transit stop or an existing stop along a high quality transit corridor. The City’s TPA, as determined by the Southern California Association of Governments (SCAG), consists of approximately ½ mile measured along both sides of the State Route 91.

The prior MND determined that the original project meets Screening Criteria 1 and 2, because the Project’s total floor area is only 5,650 square feet and the project site is located within the City’s TPA. As such, a VMT analysis was not required for the original project, as the Projects’ VMT impacts are presumably less than significant. Therefore, no mitigation was warranted.

Addendum Finding – No Impact: The Modified Project meets the Screening Criteria 1 and 2, because the Modified Project’s total floor area is less than 50,000 square feet and the project site is located within the City’s TPA. As such, a VMT analysis was not required as the Modified Projects’ VMT impacts are presumably less than significant. c
Previous Adopted MND Finding – Less Than Significant Impact: As discussed in Section 6b, the City of Corona Vehicle Miles Traveled (VMT) Analysis Guidelines lists screening thresholds to determine if land use projects would require a VMT assessment. The City’s Guidelines also provide criteria for projects that could screen out of further analysis and would be considered to have a less-than significant impact on VMT. The original project is located within a TPA and would serve the local community; thus the original project did not require further VMT analysis. As such, impacts related to VMT, including total daily VMT per service population, would be less than significant and no mitigation was warranted.

Addendum Finding – Less Than Significant Impact: As previously discussed, the Modified Project meets the Screening Criteria 1 and 2, because the Modified Project’s total floor area is less than 50,000 square feet and the project site is located within the City’s TPA. As such, a VMT analysis was not required as the Modified Projects’ VMT impacts are presumably less than significant.
d.

See discussion under 6c.
e.

Previous Adopted MND Finding – No Impact: The closest airport is Corona Municipal Airport which is approximately 1.3 miles northwest of the project site. As illustrated in the Riverside County Airport Land Use Compatibility Plan for Corona Municipal Airport, the project site is not located within any land use compatibility zones. As such, the prior MND determined that the original project would not obstruct or change air traffic patterns. There would be no impacts, and thus, no mitigation was warranted.

Addendum Finding – No Impact: The level impact in this area remains the same as originally identified in the prior MND for the Modified Project because the project site has not changed and continues to be outside of any land use compatibility zones.

As such, no impacts are anticipated, and no mitigation is warranted. f.

Previous Adopted MND Finding – Less Than Significant Impact: The design of the original project’s access, internal circulation, and surrounding circulation were reviewed for approval by the City Traffic Engineer for traffic hazards and the Fire Department for adequate fire and emergency access. 2
nd Street is classified by the General Plan as a secondary 4-lane roadway which requires an ultimate right-of-way width of 88 feet, with 64 feet of roadway from curb-to-curb. However, the segment of 2nd Street that abuts the project site will be required to be improved as a modified secondary roadway having an ultimate right-of-way that will vary. The original project did not require additional street dedication; however, the project applicant was required to construct the missing public improvements on the north half of 2nd Street adjacent to the project site which shall include the construction of the missing roadway width, curb and gutter, and a six-foot wide sidewalk. Ultimately, the north half of 2nd Street measured from the street centerline will vary in width from 39 feet to 42 feet.

Additionally, the original project was required to install a pedestrian crosswalk across 2nd Street at the intersection of 2nd Street

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 25 Environmental Checklist

and the SR-91 eastbound on-ramp to provide pedestrian connectivity to and from the Project site. Implementation of the crosswalk would require coordination with Caltrans because it would require a modification to the existing Caltrans traffic signals at this intersection. Should Caltrans deem the crosswalk to not be feasible, the alternative option is for the applicant to provide a sidewalk along the north side of 2nd Street from the easterly limits of the Project frontage to the intersection of 2nd Street and Buena Vista Avenue. This requirement was placed as a condition of approval for the Project’s Conditions of Approval for PP2023-0007. Construction of the pedestrian connectivity would reduce impacts to traffic hazards to less than significant and no mitigation is required.

Furthermore, per the TIA (dated March 18, 2024), at buildout year 2040, the intersection at Project Driveway #2 and 2nd Street was projected to meet traffic signal warrants. However, due to intersection spacing considerations, the TIA recommended that this intersection be stop signed controlled since it is anticipated to operate at an acceptable LOS D or above as a cross-street stop-controlled intersection. The TIA also recommended the following improvements to improve circulation:
• Construct 2nd Street to its ultimate half-section width as a secondary 4-lane roadway from the westerly project boundary to the easterly project boundary.
• Construct a raised median along 2nd Steet from the SR-91 on/off ramp to Project Driveway #2. • Provide stop sign control at the project driveways.
• On-site traffic signing and striping should be implemented in conjunction with detailed construction plans for the project.
• Verify that minimum sight distance is provided at the project driveways.

A queueing analysis was also performed for Project Driveway #2 to ensure adequate vehicular stacking in 2nd Street. Based on the results of the queueing analysis, the TIA recommends the following improvement:
• Construct a 245-foot (minimum) eastbound left-turn lane at Project Driveway #2.

These improvements are a condition of approval for the Project under PP2023-0007 which would reduce impacts to less than significant. Thus, no mitigation was required under the prior MND.

Addendum Finding – Less Than Significant Impact: The Modified Project would be subject to the same roadway improvements identified in the prior MND and will be conditioned accordingly. Furthermore, two additional crosswalk locations were evaluated in the Corona C-Store Trip Generation/Pedestrian Access Evaluation (Trames Solutions, dated September 5, 2024). These included the following:
• Option 1 – Sidewalk to Buena Vista Avenue
• Option 2 – Mid-Block Crossing on 2nd Street
• Option 3 (original option) – 2
nd Street/SR-91
As previously discussed, Option 2 was not recommended by Trames Solutions. Option 3 was originally required for the original project and evaluated in the prior MND. This crosswalk remains as a condition of approval with Option 1 as an alternative location for pedestrians to access the site.

Therefore, the level of impact associated with traffic hazards from design features would remain the same and no mitigation is warranted.
g.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not result in impacts related to emergency access because the project would be permitted and approved in compliance with existing safety regulations, such as the California Building Code and Fire Code (as integrated into the City’s Municipal Code) to ensure that it would not result in inadequate emergency access.

Furthermore, the proposed construction activities, including equipment and supply staging and storage, would occur within the project site and would not restrict access of emergency vehicles to the project site or adjacent areas. During construction, 2 nd
Street would remain open to ensure adequate emergency access to the project area. Thus, impacts related to inadequate emergency access during construction activities would not occur.

As described above, operation of the original project would also not result in inadequate emergency access. Direct access to the project site would be provided from 2nd Street. The driveways and on-site circulation constructed by the project would be

City of Corona 26 Environmental Checklist

evaluated through the City’s permitting procedures to meet the City’s design standards that provides adequate turning space for passenger cars, fire trucks, and delivery trucks. The project is also required to provide fire suppression facilities (e.g., hydrants and sprinklers). The Corona Fire Department (CFD) would review the development plans as part of the plan check and permitting procedures to ensure adequate emergency access pursuant to the requirements in Section 503 of the California Fire Code (Title 24, California Code of Regulations, Part 9). As a result, impacts related to inadequate emergency access would not occur.

Addendum Finding – No Impact: The Modified Project would be subject to the same existing safety regulations such as the California Building Code and Fire Code (as integrated into the City’s Municipal Code) to ensure that it would not result in inadequate emergency access. Construction activities associated with the Modified Project would also be subject to the city’s grading regulations. The Modified Project has been reviewed by the applicable city departments including Building, Fire, and Traffic to ensure that the project has adequate access and on-site circulation. Therefore, the level of impact remains the same as originally determined in the prior MND and no mitigation is warranted. h.

Discussion:
a.

Previous Adopted MND Finding – No Impact: The City of Corona participates in the Multiple Species Habitat Conservation Plan (MSHCP) which is a habitat conservation plan for Western Riverside County that identifies land to be preserved for habitat for threatened, endangered or key sensitive populations of plant and wildlife species. The project site is located within the MSHCP area. However, the project site is not within any MSHCP designated Criteria Areas or Subunits. The project site is also not located within plan-defined areas requiring surveys for criteria area species, narrow endemic species, amphibian species, or mammalian species, including burrowing owl. The Project Applicant is required to pay applicable mitigation fees related to the MSHCP. This fee will be used to acquire and preserve vegetation communities and natural areas, which are known to support these sensitive species. Therefore, the prior MND found that development of the original project is not anticipated to have impacts to endangered species or habit and further mitigation is required.

Addendum Finding – Less Than Significant Impact: The Modified Project would be subject to the same mitigation fees related the MSHCP. Therefore, the level of impact remains the same as previously identified in the prior MND and no mitigation is required.

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 27 Environmental Checklist

b.

Previous Adopted MND Finding – No Impact: Section 6.1.2 of the MSHCP defines Riparian/Riverine areas as “lands which contain Habitat dominated by trees, shrubs, persistent emergent, or emergent mosses and lichens, which occur close to or depend upon soil moisture from a nearby fresh water source; or areas with fresh water flow during all or a portion of the year. The project site is comprised of two remnant parcels that were previously developed for commercial and residential purposes prior to the SR-91 widening project occurring in 2016. Furthermore, the project site is located in a development area surrounded by a freeway, roadways, and commercial and residential developments. The project site vacant and does not contain trees, shrubs, fresh water sources or wetlands. Therefore, the prior MND determined that development of the original project would result in no impacts to riparian habitat or sensitive natural communities, and no mitigation was warranted.

Addendum Finding – Less Than Significant Impact: The “no impact” finding remains the same with development of the Modified Project because the project proposes no expansion to the previously analyzed project site. The proposed use continues to be for commercial purposes, and the layout is generally the same as before. Therefore, no impacts are anticipated, and no mitigation is required.
c.

See discussion under 7b.
d.

Previous Adopted MND Finding – No Impact: The project site has been vacant since 2016 and used as storage area for the SR-91 widening project. The project site is adjacent to a heavily traveled State Route, it will not have any impacts to nor will it interfere with wildlife corridors or migratory species. There are also no trees on the project site. Therefore, the prior MND found that development of the original project would have no impacts wildlife corridors or migratory species.

Addendum Finding – No Impact: The “no impact” finding remains the same with development of the Modified Project as there has been no expansion to the originally analyzed project site that would require additional analysis. There have been no trees or landscaping installed on the site since the adoption of the prior MND that could potentially support wildlife or migratory species.

Previous Adopted MND Finding – Less Than Significant Impact: The previous MND determined that the original project would result in a less than significant impacts related to transporting or accidental release of hazardous materials.

Addendum Finding – Less Than Significant Impact: Implementation of the Modified Project would not change the previous “less than significant finding” determination because the Modified Project would not increase the potential for significant impacts regarding the transport, use and disposal of hazardous materials. The construction operations associated with the proposed Modified Project could involve the handling of incidental amounts of hazardous substances, such as fuel and oil.

Additionally, long-term maintenance activities of the onsite landscaping could involve the use of pesticides. The avoid pubic exposure to hazardous materials, the Modified Project would be subject to local, state and federal laws and regulations regarding the handling and storage of hazardous materials. This would reduce the potential impact of creating a significant hazard to the public or the environment through the routine transport, use or disposal of hazardous materials to less than significant. Compared to the original project, the Modified Project would result in the same level of impact previously determined.
b.

See discussion under 9a.
c.

Previous Adopted MND Finding – Less Than Significant Impact: The nearest school to the Project site is Orange Grove High School located approximately 140 feet southeast of the Project site. The previous MND determined that the original project would not emit hazardous emissions within 0.25 miles of an existing of proposed school.

Addendum Finding – Less Than Significant Impact: Construction of the Modified Project would involve the use, storage and disposal of small amounts of hazardous materials on the Project site. The operations of the commercial development would also involve the use of small hazardous materials related to the maintenance of the buildings, landscaping and other features of the site. The use of these hazardous materials would be limited and used and disposed of in compliance with

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 29 Environmental Checklist

federal, state, and local regulations, which would reduce the potential for accidental release into the environment near a school. The emissions that would be generated from construction and operation of the Project were evaluated in the air quality analysis discussed above, and the emissions generated from the Project would not cause or contribute to an exceedance of the federal or state air quality standards.

The Project’s commercial use includes a gas station which will install gasoline underground storage tanks (USTs) on-site. The USTs would be subject to California’s UST regulations including the UST Program which is overseen by the California State Water Resources Control Board. The UST Program is intended to protect public health and safety, the environment and the State waters from discharges and releases of hazardous substances from the USTs.

Thus, the Modified Project would not emit hazardous or handle acutely hazardous materials, substances, or waste near a school, and impacts would be less than significant.

Previous Adopted MND Finding – No Impact: The closest airport is the Corona Municipal Airport, which is approximately

1.3 miles northwest of the Project site. Based on the Riverside County Airport Land Use Compatibility Plan (ALUCP), the project site is not within any identified safety or compatibility zone. The previous MND determined that the original project would not conflict with the ALUCP.

Addendum Finding – No Impact: The Modified Project would not increase potential airport related hazards to the Corona Municipal Airport. The project would occur in the same general area and would not be within an airport influence area.

Compared to the original project, the Modified Project would result in the same level of impact. f.

Previous Adopted MND Finding – No Impact: The previous MND found that the construction and operation of the original project would not impair the implementation of emergency response plans or evaluation plans.

Addendum Finding – No Impact: The proposed Modified Project would not increase impacts associated with conflicts with adopted emergency plans. The Modified Project would not increase the population in the City because the Modified Project is a commercial development. The construction activities for the Modified Project would not involve any activities that would physically impair or interfere with emergency response plans for the project site. During construction, there could be the potential for temporary lane closures to allow for utility connections and traffic improvements. The temporary lane closures would be for a short period of time and would not interfere with emergency response plans. Additionally, the construction activities for the project would be coordinated with the City, which would identify if traffic controls are needed to maintain emergency response plans. With compliance with City traffic control requirements, potential construction impacts with emergency response plans would be less than significant. Compared to the previously adopted /MND, implementation of the Modified Project would result in the same level of impact in regard to potential conflicts with emergency response plans or evacuation plans for the area.
g.

Previous Adopted MND Finding – No Impact: The previous MND determined that the original project was not in a Fire Hazard Area and would not expose people or structures to significant wildland fire risks.

Addendum Finding – No Impact: The Modified Project would not increase potential to expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fire. As defined in Chapter 3.36 of the Corona Municipal Code, “High Fire Risk Area” applies to any property currently within the City or subsequently annexed into the City, which is also located within or immediately adjacent to the Cleveland National Forest, as well as the urban/wildland interface area approximately 1.5 miles in width running parallel to the boundary of the Cleveland National Forest from the Orange County line to the Indian Truck Trail turnoff on Interstate 15. The project site is not located in close proximity to the Cleveland National Forest nor is it considered an area that can be described as a wildland area. The project site is an infill site located adjacent to the SR-91 freeway and in an urbanized area. Due to the urbanized nature of the surrounding area, the proposed development would not be considered at high risk for fire hazards. Furthermore, all development within the City is required to comply with all fire code requirements associated with adequate fire access, fire flows, and number of hydrants.

Compared to the previously adopted MND, the Modified Project would result in the same level of fire hazard impacts.

Previous Adopted MND Finding – Less Than Significant Impact: A Noise Memorandum for the originalprojectwas prepared by Ganddini Group, dated April 24, 2023 to analyze construction noise impacts associated with the original project. The prior MND determined that the original project would not result in adverse construction noise impacts or long-term operation noise impacts that would exceed local noise standards.

Addendum Finding – No Impact: A Focused Noise Study was prepared for the Modified Project by Ganddini Group, dated August 20, 2024. The following discusses the Modified Project’s potential short-term and long-term noise impacts.

Short-term (Construction) Noise Impact
Construction of the Modified Project would include preparation, grading, paving, building, construction and architectural coating.

Ground-borne noise and other types of construction related noise impacts would typically occur during excavation activities of the grading phase which has the potential to create the highest levels of noise. Construction of the Modified Project is anticipated to last approximately 8 months. Therefore, construction would be short-term and, but can be reduced to a less than significant level by the city’s Municipal Code. Per CMC Chapter 17.84, construction activities are prohibited between the hours of 8:00 p.m. to 7:00 a.m. Monday through Saturday, and 6:00 p.m. to 10:00 a.m. on Sundays and Federal holidays. This will prevent nuisance noise impacts during sensitive time periods for the neighboring commercial and business park properties.

Therefore, no noise mitigation is required of the applicant.

Long-term (Operational) Noise Impacts
Long-term noise impacts associated with the project would be generated from parking lot noise (car engines, doors closing and opening), mechanical HVAC equipment, the carwash drying system associated with the carwash tunnel, and the vacuum systems associated with the 11 vacuum stalls. The project is subject to the City’s noise standards for stationary noise under CMC Section 17.84.040(C). The stationary noise standards are shown in Table 10-A. The criteria is dependent upon the zoning of the receiving land use and the zoning of the source land use. If the receiving and source land uses are located in two different zones, then the standard of the lower standard applies. Furthermore, if the ambient noise level exceeds the resulting standards, the ambient shall be the standard.

The nearest sensitive receptors to the project site are existing multiple family residential uses located approximately 560 feet east (along Buena Vista Avenue), 570 feet south, and 781 feet west (along D Street). There is also a mobile home park located approximately 796 feet southwest (along Lincoln Avenue) of the project site and another mobile home park located approximately 315 feet north (on the other side of the SR-91 freeway) of the project site.

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 31 Environmental Checklist

Table 10-A: City of Corona Stationary Noise Standards
Operational noise associated with the Modified Project is not anticipated to be impactful to the surrounding sensitive receptors because the project site is separated from the sensitive receptors by distance and structures (i.e., buildings) which would help to minimize noise emitted from the project site. All mechanical units will be placed either indoors or on the rooftop behind parapet walls which would help to minimize noise. Also, noise associated with the commercial uses would be minimized by the adjacent freeway noise because of the elevated ambient noise levels due to its location adjacent to SR-91.

As shown in Table 10-B, the Modified Project would not violate the City’s stationary noise standards and therefore, would not result in a significant noise impact. No mitigation is required.

Previous Adopted MND Finding – No Impact: The closest airport is the Corona Municipal Airport, which is approximately

1.3 miles northwest of the Project site. Based on the Riverside County Airport Land Use Compatibility Plan (ALUCP), the project site is not within any identified safety or compatibility zone. The previous MND determined that the original project would not conflict with the ALUCP.

Addendum Finding – No Impact: The Modified Project would not increase potential airport related hazards to the Corona Municipal Airport. The project would occur in the same general area and would not be within an airport influence area.

Compared to the original project, the Modified Project would result in the same level of impact.

Previous Adopted MND Finding – No Impact: The Corona Fire Department (CFD), Station 2 will provide all emergency and medical aid calls to the project site. Fire Station 2 is located at 225 E. Harrison Street, approximately 0.92-mile from the project site, and is equipped with a paramedic fire engine company, a paramedic fire truck company, a water tender, and a reserve fire engine. A total of two, eight-person suppression crews staff the fire station 24 hours a day. Average response time to the project site is estimated to be approximately five minutes including travel time and turn-out time. Therefore, the prior MND determined that response times to the project site would not be impacted, and the project would not require the construction of new fire protection facilities.

Addendum Finding – No Impact: The Modified Project would result in the same “no impact” finding as the project site remains the same size as before and the intended use remains commercial. The project’s anticipated impact to fire protection would remain unchanged.
b.

Previous Adopted MND Finding – No Impact: The City of Corona Police Department will provide patrol and emergency response to the project site. The Corona Police Department presently has over 200 employees, including officers and support staff and is stationed at 730 Corporation Yard Way which is approximately 0.5 miles from the project site. The City’s police patrol officers work assigned zones throughout the city; therefore, officers responding to the project site can come from either the city’s police station or from their assigned zone while on patrol. Therefore, the prior MND determined that the original project would not impact police services and would not require the construction of new police protection facilities.

Addendum Finding – No Impact: The Modified Project would result in the same “no impact” finding as the project site remains the same size as before and the intended use remains commercial. The project’s anticipated impact to police

services would remain unchanged.
c.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not impact school services because the project is a commercial development which would not generate student enrollment in the Corona Norco Unified School District. As part of the development impact fees, the project applicant is required to pay school fees based on the square footage of the project at the time of building permits issuance. Therefore, with the required school fee payment to the school district, no additional mitigation was necessary.

Addendum Finding – No Impact: The Modified Project would result in the same “no impact” finding because the project continues to be for commercial use and the project applicant will be required to pay school fees as noted above. Therefore, no mitigation is required.
d.

Previous Adopted MND Finding – No Impact: To offset the project’s potential impact on existing city services, such as streets, parks, library services, police and fire services, the project applicant is required by Corona Municipal Code Chapter

16.23 to pay the adopted development impact fees that are in effect at the time of building permit issuance to offset the added services and infrastructure demands resulting from this project. Therefore, the prior MND determined no additional mitigation is warranted beyond the requirement to pay development impact fees.

Addendum Finding – No Impact: The Modified Project would result in the same “no impact” finding because the project applicant will be required to pay the applicable development impact fees as noted above. Therefore, no mitigation is required. e.

Previous Adopted MND Finding – Less than significant impact: The prior MND determined that the original project would result in a less than significant impact as it pertains to exceeding wastewater treatment requirements.

Addendum Finding – Less than significant impact: The Modified Project would in the same level of impact as previously determined because, all projects are required by the City’s Utilities Department to construct or guarantee the construction of all necessary public water and sewer facilities needed to serve the project. All water and sewer facilities are required to be designed per the standards of the Utilities Department and Riverside County Department of Health Services and will be reviewed by the Utilities Department during the plan check process. Also, Water Reclamation Facility #1 located at 2250 Railroad Street would serve the proposed development and has adequate capacity. The facility currently has a capacity to treat 11.5 mgd (million gallons per day) of sewer. This would reduce the impacts to less than a significant level and therefore, no mitigation would be required.
b.

Previous Adopted MND Finding – Less than significant impact: Per the Hydrology And Hydraulics Study (Woodward Group, May 2024) that was prepared for the original project, the site’s main drainage pattern will be similar to the existing condition. The original project would not result in the construction of new water and wastewater treatment facilities. Therefore, impacts to water and wastewater treatment facilities would be less than significant.

Addendum Finding – Less than significant impact: An updated Hydrology And Hydraulics Study (Woodward Group, August 2024) that was prepared for the Modified Project. The site’s main drainage pattern will be similar to the existing condition. There is no off-site drainage runoff from the area surrounding the site. The proposed on-site sheet flows throughout the site layout and conveys the discharge into an infiltration trench within the site. The infiltration trench was based to contain the 85th percentile 24-hour duration storm event for water quality volume only in accordance with section 4 of the Water Quality Management Plan – Technical Guidance Document for the Santa Ana Region of Riverside County. The Flood events larger than water quality volume, when the infiltration trench has reached capacity, the excess runoff will be discharged into W 2nd Street through a proposed parkway drain. Storm flows generated by the project site travel easterly along 2nd street and Buena Vista Avenue. The infiltration trench will contain and infiltrate the water quality volume for the 85th percentile 24-hour duration storm event and mitigate for a 100 yr. flood pre/post condition. The infiltration trench is located along the northerly property line and will take care of flows from the roof drains, parking lot of the site, and concrete flatwork. For emergency purposes, the parkway drain will serve as the 100-year overflow and discharge into W. Second Ave. existing curb and gutter.

In the pre-development condition, the project site is expected to discharge 22,687 cubic feet of drainage. In post-development condition, the project site is expected to discharge 26,137 cubic feet of drainage. The pre/post difference is 3,450 cubic feet of drainage. The infiltration volume capacity is 3,567 cubic feet, which is sufficient to accommodate the difference of 3,450 cub feet of drainage. Therefore, the Modified Project’s impact to storm drains would be less than significant and no mitigation is required.
d.

Previous Adopted MND Finding – Less than significant impact: A preliminary water quality management plan (WQMP, Woodward Group, revised May 25, 2024) was prepared to evaluate the original project. The prior MND determined that the project would not violate a water quality management plan. Impacts would be less than significant.

Addendum Finding – Less than significant impact: An updated preliminary water quality management plan (WQMP, Woodward Group, revised August 12, 2024) was prepared the project to evaluate the Modified Project. Per the preliminary WQMP, the site currently drains to the southeast corner of the lot and into a city-maintained storm water system. The Modified Project intends to maintain the same drainage pattern. Storm water from the site will be treated by an infiltration trench that is proposed at the southeast corner of the site which will be designed to mimic and exceed the site’s existing infiltration capacity. All flows exceeding the design capture volume will be released from the site and flow into 2nd Street through a parkway drain. As part of the project’s grading permit process, the applicant is required to submit a final WQMP and the city’s Public Works inspector also inspects the project site for compliance with the final approved WQMP during the on-site grading process and at time of project completion. Therefore, the project would not impact water quality or violate water quality standards and no mitigation is required.

The Modified Project would connect to the 12-inch sewer line in West 2nd Street. As required for all projects by the City’s Utilities Department, the project is required to construct or guarantee the construction of all necessary public water and sewer

facilities needed to serve the project. All water and sewer facilities are required to be designed per the standards of the Utilities Department and Riverside County Department of Health Services and will be reviewed by the Utilities Department during the plan check process. Thus, impacts would be less than significant e.

See discussion under 12a.
f.

Previous Adopted MND Finding – Less than significant impact: Waste Management (WM) is contracted by the City of Corona as the sole hauler of solid waste and provider of recycling services. WM provides refuse collection to residential, commercial, and industrial customers. Solid waste from the project would be transported to the El Sobrante landfill located at 10910 Dawson Canyon in Corona. The El Sobrante landfill accepts a maximum 16,054 tons of waste per day and has a remaining capacity of 143,977,170 tons and an estimated closure date of 2051. Per the General Plan Technical Update EIR, the County of Riverside is required to maintain 15 years identified disposal capacity, or have a plan to transform or divert its waste, pursuant to AB 939. Thus, while General Plan buildout could occur after 2051, the County would be required to have 15 years identified disposal capacity after that date. There is adequate landfill capacity in the region for solid waste that would be generated by the 2020-2040 GeneralPlan buildout. Furthermore, new developments approved by the City would berequired to contain storage areas for recyclable materials in conformance with California Public Resources Code Sections 42900 et seq., and the City of Corona Municipal Code Chapter 8.20 (Collection of Refuse and Recyclable Materials). Solid waste diversion program would continue operating and would have adequate capacity to accept all future wastes and recyclables to reduce landfilled waste. Therefore, the prior MND determined that the original project would result in less than significant impacts to landfills and no mitigation is required.

Addendum Finding – Less than significant impact: Implementation of the Modified Project would result in the same level of impact because, and as discussed above, there is adequate capacity in the region for solid waste that would be generated by the 2020-2040 General Plan buildout. Furthermore, the Modified Project would be required to contain storage areas for recyclable materials in conformance with California Public Resources Code Sections 42900 et seq., and the City of Corona Municipal Code Chapter 8.20 (Collection of Refuse and Recyclable Materials). Solid waste diversion program would continue operating and would have adequate capacity to accept all future wastes and recyclables to reduce landfilled waste. Compared to the original project, the Modified Project would result in the same level of impact as it pertains to landfills. g.

Previous Adopted MND Finding – Less than significant impact: The prior MND determined that the project would result in less than significant impact related to potential conflicts with solid waste regulations, because the project would be required to comply with all federal, State, and local regulations related to solid waste. Furthermore, the project would be required comply with all standards related to solid waste diversion, reduction, and recycling during Project construction and operation.

Addendum Finding – Less than significant impact: Implementation of the Modified Project would result in a less than significant impact related to potential conflicts with solid waste regulations because the Modified Project would be required to comply with all federal, State, and local regulations related to solid waste.

Previous Adopted MND Finding – Less than significant impact: According to Figure CD-1 (Scenic Corridors) of the City’s General Plan (2020-2040), the project site is not adjacent to any local or state designated scenic corridor. However, I-15 and SR-91 are designated as “State Eligible Scenic Corridors”. The prior MND determined that the project’s impacts to a scenic vista or highway would be less than significant because the project would be designed per the development standards established by the Corona Municipal Code for the C-3 zone. Also, the project’s architecture would be developed in a manner that is aesthetically compatible with its surrounding area, including details relating to architecture and landscaping. The proposed project would provide paved driveway accesses, screen fencing and landscaping around the perimeters of the property and short screen wall at the drive through lane to buffer vehicle headlights light from nearby drivers.

Addendum Finding – Less than significant impact: The Modified Project would not increase the potential to substantially impact scenic resources or corridors or degrade the visual character of the site and surroundings because the Modified Project is located on the same site that was previously analyzed. The Modified Project would be subject to the C-3 zone development standards. The overall design of the project, including the new freeway sign with the electronic message center, would be reviewed through the city’s precise plan process to ensure compliance with the applicable standards and that the architecture of the commercial buildings are developed in a manner that is aesthetically compatible with its surrounding area, including details relating to architecture and landscaping. Therefore, compared to the original project, the Modified Project would result in the same level of impacts to scenic highways.

Previous Adopted MND Finding – Less than significant impact: The prior MND determined that the project’s impacts to light and glare would be less than significant because the project site is located in a developed area with existing ambient lighting. The area contains existing street light poles along both sides of 2nd Street, lighting from the commercial center parking lot located to the south of the project site, and lighting (light poles and vehicle headlights) along the SR-91 freeway. Additionally, the project is subject to CMC Section 17.84.070, which requires all areas of exterior lighting shall be designed to direct light downward with minimal spillover onto adjacent residences, sensitive land uses, and open space. There are no residential uses located immediately next to the project site.

Addendum Finding – Less than significant impact: The Modified Project would not increase the potential to substantially create more glare than the original project because the Modified Project is located on the same site that was previously analyzed. The site is surrounded by ambient lighting, and the Modified Project would be subject to CMC Section 17.84.070, which requires all areas of exterior lighting shall be designed to direct light downward with minimal spillover onto adjacent residences, sensitive land uses, and open space. There are no residential uses located immediately next to the project site.

Compared to the original project, the Modified Project would result in the same level of light and glare impacts. d.

Previous Adopted MND Finding – Less than significant impact: The prior MND determined that the project site would not result in impacts to scenic resources because the project site is not located adjacent to any forest lands or historic buildings within scenic highways. While SR-91 is a designated “State Eligible Scenic Corridors”, the project’s design and site features including screen walls and perimeter landscaping as discussed under 13.a, will enhance the aesthetic of the site in a manner that will not detract from the SR-91.

Previous Adopted MND Finding – Potentially Significant Unless Mitigation Incorporated: The prior MND evaluated the original project’s potential impacts to the issues analyzed under Section 14, Cultural Resources. A cultural resource analysis was performed for a 4.01-acre parcel (APN 118-270-055) located southeast of the project site, The analysis was prepared

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 39 Environmental Checklist

Dudek, dated April 2024, for a multiple family residential project that was proposed on the 4.01-acre property. The project site is a remnant portion of the 4.01-acre property as as such, the results of the cultural resource analysis for the 4.01-acre property would likely be applicable to the project site which is the reason the cultural resource analysis was included in the prior MND.

A records search for the 4.01-acre property and surrounding area was conducted through the Eastern Information Center (EIC) at the University of California Riverside. The records search indicated that 40 previous studies have been conducted within a 1-mile of the 4.01-acre site. Of the 40 previous studies, three studies intersect the Project site, of which none of the three identified cultural resources within the Project site. While EIC records search did identify 284 cultural resources within 1-mile of the Project site, none of these cultural resources intersected the 4.01-acre property. The records research also included a response from the Native American Heritage Commission on January 19, 2024, stating that results were negative for Native American resources on the subject Project site.

In addition to the record search, the cultural resources analysis also included a field survey which was conducted on January 8, 2024. The field survey noted the 4.01-acre site had remnants of an asphalt surface, likely from the previous mobile home park, grass, gravels and a few trees present with some scattered debris. The field survey also did not identify any cultural resources.

Dudek concluded that although no known significant cultural resources could be impacted by the multiple family residential project, the current status of the property may have affected the potential to discover any surface artifacts. Given that the previous development within the site might have masked archaeological deposits, there is a potential that buried historical resource deposits may be present within the project boundaries. Therefore, Dudek recommended that the multiple family residential project be allowed to proceed with the implementation of a cultural resources monitoring program conducted by an archaeologist and Native American representative(s) during grading of the project site. Dudek recommended Mitigation Measures MM CUL-1 and MM-CUL 2 to reduce impacts to cultural resources to less than significant. The mitigation measures generally require a cultural resource monitoring program during grading activities, impacts to historical resources would be reduced to less-than-significant levels. Since the commercial project site is a remnant portion of the 4.01-acre property, the mitigation measure that were recommended for the multiple family residential project are being recommended for the commercial project. The commercial project’s compliance with MM CUL-1 and MM-CUL 2 would reduce impacts to cultural resources to less than significant. See Section 17, Tribal Cultural Resources for the mitigation measures.

Addendum Finding – Potentially Significant Unless Mitigation Incorporated: The Modified Project would not increase the potential for impacts to Cultural Resources because the Modified Project is proposed on the same project site that was previously analyzed. The Modified Project would be subject to the same mitigation measures that were adopted in the prior MND for the original project. With implementation of Mitigation Measures MM CUL-1 and MM-CUL 2, potential impacts would be less than significant. See Section 17, Tribal Cultural Resources for the mitigation measures.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not result in the conversion of prime farmland, unique farmland, or farmland of statewide importance to a non-agricultural use.

Addendum Finding – No Impact: Implementation of the Modified Project would not increase the potential to convert prime farmland, unique farmland, or farmland of statewide importance to a non-agricultural use. According to the California Department of Conservation’s (CDC) California Important Farmland Finder, the Project site is classified as “Urban and Built-Up Land”. The “Urban and Built-Up Land” classification describes land that is occupied by structures with a building density of at least 1 unit to 1.5 acres, or approximately 6 structures to a 10-acre parcel(CDC, 2018). The nearest location of Farmland to the project site is a parcel containing Farmland of local importance that is located approximately 2,500 feet to the north near the intersection of Lincoln Avenue and Railroad Street. Due to the site’s distance from the designated Farmland, the Modified Project does not have the potential to convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland) to non-agricultural use. Compared to the original project, the Modified Project would result in the same level of impact to agricultural resources.

Previous Adopted MND Finding – Less Than Significant Impact: The previous MND estimated that the amount of greenhouse gas emissions the original project would generate is approximately 2,758.27 MTCO2e per year. Since this is less than SCAQMD’s numeric threshold of 3,000 MtCO2e per year, the project’s impacts would be less than significant.

Addendum Finding – Less Than Significant Impact: Per the Modified Project’s Air Quality, Global Climate Change, and Energy (Ganddini, July 26, 2024), the Modified Project’s estimated GHG emissions is approximately 2,442.30 MTCO2e per year. Since this is less than SCAQMD’s numeric threshold of 3,000 MtCO2e per year, the Modified Project’s impacts would be less than significant. Compared to the original project, the Modified Project would result in the same level of impact as it pertains to greenhouse gas emissions.

Addendum Finding – No Impact: Implementation of the Modified Project would not increase the potential for causing a substantial change in the significance of a tribal cultural resource, as defined in Public Resources Code Section 21074, and that is listed or eligible for listing in the California Register of Historic Resources, or in a Corona Register of Historic Resources, because the Modified Project is proposed on the same site as previously analyzed. Compared to the original project, the Modified Project would result in the same level of impact. b.

Previous Adopted MND Finding – Potentially Significant Unless Mitigation Incorporated: The original project was subject to tribal consultation under SB 18 and AB 52. The Planning and Development Department obtained a list of local Native American tribes from the Native American Heritage Commission (NAHC) on June 19, 2013. All tribes on the NAHC list were invited to consult on the project via consultation letters, dated October 18, 2023. The Planning and Development Department also notified the AB 52 tribes via the City’s project transmittal in May 2023.

On October 31, 2023, the Rincon Band of Luiseno Indians responded to the notification and requested consultation on the Project. The consultation process occurred throughout the duration of the Project. The Rincon Band and Planning & Development Department staff were not able to come a mutual agreement on mitigation measures for the Project, and subsequently, staff concluded the consultation process in June 2024.

Per the prior MND, the original project would be required to implement the same mitigation measures for the multiple family residential project approved for development on a 4.01-acre parcel located to the southeast of the project. This is because the project site is a remnant portion of the larger 4.01-acre parcel. As noted throughout this MND, both sites were previously a single property and developed with a mobile home park prior to the SR-91 widening project in 2016 and extension of 2nd Street which bisected the mobile home park into two separate areas. A cultural resource analysis was performed for the 4.01-acre parcel by Dudek, dated April 2024, for the multiple family residential project. The cultural resource analysis is filed with the multiple family residential project Precise Plan 2023-0011. The analysis included a records search for the 4.01-acre parcel and surrounding area which was conducted by Dudek through the Eastern Information Center (EIC) at the University of California Riverside. The records search indicated that 40 previous studies have been conducted within a 1-mile of the Project site. Of the 40 previous studies, three studies intersect the 4.01-acre parcel, of which none of the three identified cultural resources were within the 4.01-acre parcel. While EIC records search did identify 284 cultural resources within 1-mile of the

4.01-acre parcel, none of these cultural resources intersected the parcel. In addition to the records search, a field survey was conducted on the 4.01-acre parcel on January 8, 2024. The field survey noted the project site had remnants of an asphalt surface, likely from the previous mobile home park, grass, gravels and a few trees present with some scattered debris. The field survey also did not identify any cultural resources.

Based on the results of the cultural resource analysis that was prepared by Dudek for the 4.01-acre site, it is unlikely that the project site would contain cultural resources since both sites were previously developed as a single property. However, as with the 4.01-acre property, although no known significant cultural resources could be impacted by the original project, the

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 42 Environmental Checklist

current status of the property may have affected the potential to discover any surface artifacts. Given that the previous development within the project site might have masked archaeological deposits, there is a potential that buried historical resource deposits may be present within the project boundaries. Therefore, the prior MND recommended that the original project be allowed to proceed with the implementation of a cultural resources monitoring program conducted by an archaeologist and Native American representative(s) during grading of the property. With implementation of Mitigation Measures MM CUL-1 through MM-CUL 4, generally requiring a cultural resource monitoring program during grading activities, impacts to tribal cultural resources would be reduced to less-than-significant levels.

Addendum Finding – Potentially Significant Unless Mitigation Incorporated: Implementation of the Modified Project would not increase the potential to impact tribal cultural resources because the Modified Project is proposed on the same site that was previously analyzed. Implementation of the previously adopted mitigation measures MM CUL-1 through MM-CUL 4 would reduce impacts to less than significant. Compared to the original project, the Modified Project would result in the same level of impact with implementation of the required mitigation measures.

Mitigation Measures
MM CUL-1 Archaeological Monitoring. Prior to the issuance of a grading permit, the Project Applicant shall retain and enter a monitoring and mitigation service contract with a qualified Archaeologist (“Archaeological Monitor”) for mitigation monitoring services and implement a Cultural Resource Monitoring Program (CRMP). At least 30 days prior to issuance of grading permits, a copy of the executed agreement between the Project Applicant and Archaeologist shall be submitted to the Planning and Development Department:
▪ A CRMP shall be prepared to guide the procedures and protocols of an archaeological mitigation monitoring program that shall be implemented during initial onsite and offsite ground disturbing activities. The CRMP shall include, but not be limited to, the Project grading and development schedule; approved Project cultural resources mitigation measures and conditions of approval; monitoring procedures; protocols for the identification, assessment, collection, and analysis of any resource(s) observed during grading; curation guidelines; and coordination with project personnel, City staff, and any participating Native American tribe(s). The Rincon Band of Luiseño Indians shall be notified of any discoveries. The final CRMP shall be submitted to the City Project planner and/or inspector, the appropriate Project supervisor/engineer/etc., and monitoring Native American tribe(s), if any.
• The Archaeological Monitor shall be invited to a preconstruction meeting with construction personnel and City and tribal representatives. The attending archaeologist shall review the provisions of the CRMP and answer any applicable questions. • Full-time monitoring shall occur throughout the entire Project area, including all off-site improvement areas, during initial ground-disturbing activities. Full-time monitoring shall continue until the Archaeological Monitor determines that the overall sensitivity of the Project area is low as a result of mitigation monitoring and shall have the authority to modify and reduce the monitoring program to either periodic spot-checks or complete suspension of the monitoring program. Should the monitor(s) determine that there are no cultural resources within the Project site or off-site improvement areas, or should the sensitivity be reduced to low during monitoring, all monitoring shall cease.

MM CUL-2 Inadvertent Discovery and Native American Notification. In the event that a significant cultural resource is discovered during ground disturbance activities, the project archaeologist shall notify the City and the Rincon Band of Luiseño Indians for purposes of inviting the Tribe to participate in the CRMP implementation and to observe any continuing ground-disturbing construction activities. Further, all ground disturbance activities within 50 feet of the discovered cultural resource shall be halted and the applicant and a meeting shall be convened between the developer, the consulting archaeologist, the lead agency and a Rincon tribal representative to discuss the significance of the find. Further ground disturbance shall not resume in the area of the discovery until the appropriate treatment has been accomplished.

MM CUL-3 Paleontological Monitor. Prior to the issuance of grading permits, the Project Applicant shall submit to and receive approval from the City of a Paleontological Resources Monitoring and Mitigation Plan (PRMMP). The PRMMP shall include the provision of a trained paleontological monitor during onsite soil disturbance activities. The monitoring for paleontological resources shall be conducted on a full-time basis during the rough grading phases of the Project site within native soils that have the potential to harbor paleontological resources. The paleontological monitor shall be equipped to rapidly remove any large fossil specimens encountered during excavation. During monitoring, samples of soil shall be collected and processed to recover micro-vertebrate fossils. Processing shall include wet screen washing and microscopic examination of the residual materials to identify small vertebrate remains. If paleontological resources are unearthed or

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 43 Environmental Checklist

discovered during grading activities, the following recovery processes shall apply:
▪ Upon encountering a large deposit of bone, salvage of all bone in the area shall be conducted with additional field staff and in accordance with modern paleontological techniques. ▪ All fossils collected during the project shall be prepared to a reasonable point of identification. Excess sediment or matrix shall be removed from the specimens to reduce the bulk and cost of storage.

Itemized catalogs of all material collected and identified shall be provided to the museum repository along with the specimens.
▪ A report documenting the results of the monitoring and salvage activities and the significance of the fossils shall be prepared.
▪ All fossils collected during this work, along with the itemized inventory of these specimens, shall be deposited in a museum repository (such as the Western Science Center for Archaeology & Paleontology, the Riverside Metropolitan Museum, or the San Bernardino County Museum) for permanent curation and storage.

MM CUL-4 Discovery of Human Remains: In the event that human remains (or remains that may be human) are discovered at the project site during grading or earthmoving activities, the construction contractors, project archaeologist, and/or designated Native American Monitor shall immediately stop all activities within 100 feet of the find. The project proponent shall then inform the Riverside County Coroner and the City of Corona Planning and Development Department, Planning Division, immediately, and the coroner shall be permitted to examine the remains as required by California Health and Safety Code Section 7050.5(b). Section 7050.5 requires that excavation be stopped in the vicinity of discovered human remains until the coroner can determine whether the remains are those of a Native American. If human remains are determined as those of Native American origin, the applicant shall comply with the state relating to the disposition of Native American burials that fall within the jurisdiction of the Native American Heritage Commission (PRC Section 5097). The coroner shall contact the Native American Heritage Commission (NAHC) to determine the most likely descendant(s) (MLD). The MLD shall complete his or her inspection and make recommendations or preferences for treatment within 48 hours of being granted access to the site. The Disposition of the remains shall be overseen by the most likely descendant(s) to determine the most appropriate means of treating the human remains and any associated grave artifacts.

The specific locations of Native American burials and reburials will be proprietary and not disclosed to the general public. The locations will be documented by the consulting archaeologist in conjunction with the various stakeholders and a report of findings will be filed with the Eastern Information Center (EIC).According to California Health and Safety Code, six or more human burials at one location constitute a cemetery (Section 8100), and disturbance of Native American cemeteries is a felony (Section 7052) determined in consultation between the project proponent and the MLD. In the event that the project proponent and the MLD are in disagreement regarding the disposition of the remains, State law will apply and the median and decision process will occur with the Native American Heritage Commission (see Public Resources Code Section 5097.98(e) and 5097.94(k)).

a.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would have no impacts on fish and wildlife populations, habitat or historical sites.

Addendum Finding – No Impact: Implementation of the Modified Project would not impact fish and wildlife populations, habitat or historical sites. As discussed throughout this Addendum document, the project site was previously occupied by development prior to the SR-91 Widening Project. There is no known bodies of water, habitat, trees, vegetation that exists on the site. There are no historical sites listed on Corona Register of Historic Resources in the vicinity. Therefore, the Modified Project would not impact fish and wildlife populations, habitat or historical sites. b & c
Previous Adopted MND Finding – Potentially Significant Unless Mitigation Incorporated: Cumulative effects that would result from implementation of the Project have been evaluated throughout this IS/MND, which concludes that such impacts would not occur, would be less than significant, or would be reduced to below a level of significance with the incorporation of mitigation measures identified herein and included in the project’s conditions of approval. For example, the project is not anticipated to impact threatened or endangered species or habitat. Traffic impacts as it relates to VMT are anticipated to be less than significant because the project is located within the Transit Priority Area (TPA) which screens the project from having to have a VMT analysis performed. For the issue of Tribal Cultural Resources, mitigation measures are proposed to reduce impacts to this area to less than significant. For the issue of Greenhouse Gas Emissions, projects that are consistent with the City’s CAP are considered to have a less-than-significant individual and cumulative impact on GHG emissions. Because the original project would generate fewer than 3,000 MTCO2e/yr of GHG emissions, the original project’s impacts due to GHGs would be less-than significant. Furthermore, the analysis of the original project construction impacts due to noise demonstrates that the project’s construction related noise impacts would be less than significant because of the short-term nature of construction. Construction noise would also be subject to the City’s construction noise regulations.

Therefore, with the incorporation of mitigation measures identified herein and included in the original project’s conditions of approval, the original project’s impacts were not anticipated to be cumulatively considerable.

Addendum Finding – Potentially Significant Unless Mitigation Incorporated: No new or greater cumulative impacts would occur from the Modified Project because there is no change in land use or to the original project site. The Modified Project is required to implement the same tribal cultural resources mitigation measures identified in the previously adopted MND.
d.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not conflict with the General Plan’s short-term and long-term goals.

Addendum Finding – No Impact: Implementation of the Modified Project would not impact the General Plan’s short-term and long-term goals. The Modified Project would develop a commercial development on the project site that is consistent with the General Plan land use designation of General Commercial and C-3 commercial zoning. Furthermore, the proposed development would be consistent with the applicable policies and intent of the General Plan.

Discussion:
a, b, c & d.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not impact the areas of concern under Section 19, Wildfire because the project site is not located within a high fire hazard severity zone or adjacent to other properties that are within a high fire hazard severity zone. There are no slopes, prevailing winds, or other factors that would exacerbate wildlife risks and expose project occupants to pollutant concentrations from wildlife. Therefore, no impacts to wildfire are expected.

The project site is located in an urbanized area surrounded by developments. There are no slopes on the project site or other prevailing factors that would exacerbate or expose the site to wildlife risks. Furthermore, the proposed commercial buildings will also be constructed in accordance with the California Building Standards Code and California Fire Code which will require adequate fire suppression measures such as fire sprinklers and adequate water pressure for fire hydrants serving the project.

Therefore, no impacts are expected.

Paved roadway access is provided to the project site via a public street, 2 nd Street, which connects to Buena Vista Avenue to
the east and Lincoln Avenue to the West. Therefore, the site has adequate access in the event of an evacuation or fire-related emergency.

The project site will be graded to create level buildable pads for development. The site is not located in a downstream flood area. There are no downslopes that would expose the site to landslides, runoff or post-fire slope instability. Therefore, development of the project would not expose people or structures to risks related to landslides or flooding that could occur post-fire. No impacts are expected.

Addendum Finding – No Impact: Implementation of the Modified Project would not increase the potential to impact the areas of concern under Section 19, Wildfire, because the Modified Project is proposed on the same project site previously analyzed.

The project site is not located within a high fire hazard severity zone or adjacent to other properties that are within a high fire hazard severity zone.

Discussion
a.

Previous Adopted MND Finding – Less Than Significant Impact: The prior MND determined that the project would result in less than significant environmental impacts due to wasteful, inefficient, or unnecessary consumption of energy resources during project construction or operation.

Addendum Finding – Less Than Significant Impact: The Modified Project was evaluated in the C-Store Gas Station, Air Quality, Global Climate Change and Energy Impact Analysis, prepared by Gaddini, dated July 26, 2024. The following discusses the Modified Project’s construction and operation impacts due to wasteful, inefficient, or unnecessary consumption of energy resources during project construction or operation.

Construction
The anticipated construction schedule assumes that the proposed Modified Project would be built in approximately eight months and in one phase. The Modified Project would require grading, site preparation, and building activities during construction. Construction of the Modified Project would require energy for the manufacture and transportation of building materials, preparation of the site for grading activities, and building construction and paving activities. Petroleum fuels (e.g., diesel and gasoline) would be the primary sources of energy for these activities. The Modified Project’s electricity usage from construction is approximately 964 kWh. Approximately 468 gallons of fuel would be consumed from construction workers, 17,214 gallons of diesel fuel would be consumed by construction activities and 1,800 gallons of fuel would be consumed for vendor and hauling trips.

The Modified Project construction phase would conform to the California Air Resources Board (CARB) regulations and California emissions standards. Compliance with these regulations would result in a more efficient use of construction-related energy and would minimize or eliminate wasteful or unnecessary consumption of energy. Furthermore, idling times of construction vehicles would be limited to no more than five minutes per California Code of Regulations Title 13, Motor Vehicles, Section 2449(d)(3). This would minimize or eliminate unnecessary and wasteful consumption of fuel. Energy usage on the project site during construction would be temporary in nature and would be relatively small in comparison to the State’s available energy sources. Therefore, construction energy impacts would be less than significant, and no mitigation would be required.

Operation
Energy use consumed by the proposed project would include transportation energy demands and facilities energy demand.

The Modified Project is estimated to generate 1,644 trips per day. The estimated fuel use is 270,703 gallons of fuel per year for the operations of the project. The trip generation and VMT generated by the Project are consistent with other similar commercial uses of similar scale and configurations as reflected respectively in the Institute of Transportation Engineers (ITE) Trip General Manual (11th Edition, 2021). That is, the proposed project does not propose uses or operations that would inherently result in excessive and wasteful VMT. Furthermore, the state of California consumed approximately 4.2 billion gallons of diesel and 15.1 billion gallons of gasoline in 2015. Therefore, the increase in fuel consumption from the proposed project is insignificant in comparison to the State’s demands. Therefore, project transportation energy consumption would not be considered in efficient, wasteful or otherwise unnecessary.

Building operation and site maintenance would result in the consumption of electricity and natural gas. The Modified Project is estimated to use approximately 174,624 kWh per year and 239,049 kBTU per year. IN 2012, the non-residential sector of the County of Riverside consumed approximately 8,257 million kWh of electricity and 144 million therms of gas. Therefore, the projects electricity and gas demands are insignificant compared to the County’s demand. Furthermore, the Modified Project will be subject to California Building Standards Code Title 24 which governs energy consumption by the built environment,

Environmental: Corona Fuel Site 2nd Street Development

mechanical systems and certain fixed lighting. Therefore, the Modified Project’s energy consumption and demands would not be considered inefficient, wasteful or otherwise unnecessary. Impact would be less than significant and no mitigation is warranted.
b.

Previous Adopted MND Finding – No Impact: The prior MND determined that the project would not conflict with or obstruct a state or local plan for renewable energy or energy efficiency.

Addendum Finding – No Impact: Implementation of the Modified Project would not conflict with or obstruct a state or local plan for renewable energy or energy efficiency. The Modified Project would be subject to the energy efficiency standards in Title 24 of the California Code of Regulations, California Code of Regulations Green Building Code requirements for energy efficient buildings and appliances as well as utility energy efficiency programs implemented by Southern California Gas and Southern California Edison. The Modified Project would also be required to meet or exceed the energy standards established by the California Green Building Standards Code, Title 24, Part 11 (CalGreen), which require that new buildings reduce water consumption, employ building commissioning to increase building system efficiencies, divert construction waste from landfills, and install low pollutant-emitting finish materials. Therefore, the Modified Project would not conflict with or obstruct a local plan for renewal energy or energy efficiency and no mitigation is warranted.

REQUEST FOR CITY COUNCIL ACTION
SUBJECT:

CONDITIONAL USE PERMIT 2024-0006 FOR A 4,110-SQUARE-FOOT CARWASH WITH 11 VACUUM STALLS PROPOSED AS PART OF A 1.40-ACRE COMMERCIAL

DEVELOPMENT CONSISTING OF A GAS STATION AND CONVENIENCE STORE, LOCATED ON THE NORTH SIDE OF 2ND STREET, APPROXIMATELY 450 FEET WEST OF BUENA VISTA AVENUE IN THE C-3 (GENERAL COMMERCIAL) ZONE (APPLICANT: GREENS DEVELOPMENT)
EXECUTIVE SUMMARY:

This staff report asks the City Council to affirm the decision by the Planning and Housing Commission in granting Conditional Use Permit 2024-0006 (CUP2024-0006) to establish a 4,110 square foot self -service carwash on 1.40 acres in the C-3 (General Commercial) zone. The carwash is part of a larger development that will consist of a gas station and convenience store. The establishment of a carwash requires a conditional use permit in the C-3 zone, which is the reason for CUP2024-0006.

RECOMMENDED ACTION:

That the City Council:
a. Take no action, thereby affirming the Planning and Housing Commission’s action granting CUP2024-0006, based on the finding contained in the staff report and conditions of approval.

OR

b. Set the item for review at a subsequent meeting.

BACKGROUND & HISTORY:

Greens Development is proposing to develop two adjoining parcels that have a combined acreage of 1.40 acres for commercial purposes. The project site is located on the north side of 2
nd Street, west of Buena Vista Avenue, and south of State Route 91 (SR-91). The zoning of the project site is C-3 (General Commercial). The carwash is one element of the proposed project. Additional uses proposed on the project site include a gas station with 10 fuel pumps and a 3,725 square foot convenience store. The carwash is limited to the review under CUP2024-0006, whereas the remainder of the project is subject to review by Precise Plan 2023-0007 (PP2023-0007). The Planning and Housing Commission at its meeting on September 23, 2024, approved CUP2024-0006.

ANALYSIS:

Site Plan
The 4,110 square foot carwash facility is proposed on the western portion of the project site. The carwash tunnel is 130 feet long and plotted on the site in a manner where the openings of the tunnel are not directed towards 2nd Street. The 11 drying spaces and vacuum stalls are located on the south side of the tunnel. The eastern portions of the project site will be developed for a gas station and convenience store. The overall development provides sixteen (16) parking spaces and a trash enclosure which are to be shared among the tenants within the development. Vehicular access to the site is provided from 2nd Street via two driveways proposed at the site’s south perimeter.

The C-3 zone requires a minimum front yard setback of 10 feet along 2nd Street and no setback along the side and rear yards. As designed, the carwash complies with the setback requirements.

Vehicle access into the carwash tunnel is facilitated by a drive-through lane that splits into two lanes at the payment kiosks and merges into a single lane before the entrance into the tunnel. Section 17.76.030 of the Corona Municipal Code (CMC) requires the carwash drive-through lane to be able to accommodate at least one car before the tunnel and at least six cars from the payment kiosk. The project’s drive-through lane is designed to accommodate seven cars between the tunnel entrance and payment kiosks, and 12 cars between the payment kiosks and the entrance of the drive-through lane.

The carwash is subject to supplemental standards that are applicable to automotive related uses in Chapter 17.72 of the CMC. These standards ensure that the drive-through lane does not interfere with parking or drive aisles. The carports for drying areas are constructed of durable materials, and drying areas do not occupy required parking and drive aisles. Additionally, the use of honking horns or other amplified noise is prohibited.

The applicant’s plans demonstrate compliance with the supplemental standards.

Parking

Per the CMC’s Parking Ordinance, Chapter 17.76, the carwash is required to have at least two parking spaces per self-wash stall (tunnel). Since the carwash will operate in conjunction with the other uses planned on the project site, the overall development requires 16 parking spaces per the requirements in the Parking Ordinance. The site provides 16 spaces plus one loading space for the convenience store. The 16 parking spaces are in addition to the 11 vacuum stalls.

Elevations
The CMC prescribes no specific architectural style for commercial buildings in the C-3 zone. The applicant is proposing a contemporary architectural style for the carwash tunnel. The building features tower elements, parapet walls, metal awnings, and glazed storefronts and windows. The buildings’ primary exterior finish is stucco with splitface block and stone veneer as accent materials. The color palette consists of shades of grey and brown with green as an accent color. The rooftops are designed to accommodate mechanical equipment which will be screened from street view behind parapet walls. The vacuum canopies have a matching design to the building. The building is 26 feet in height, which complies with the CMC’s maximum allowable building height limit of 40 feet for the C-3 zone.

Landscaping
The landscaping includes a mixture of trees and palms and shrubs which will be installed within planter areas located around the perimeters of the carwash site. The landscape coverage, placement of trees, size of trees at the time of installation, and the use of drought tolerant materials comply with the CMC’s Landscape Ordinance, Chapter 17.70.

Surroundings
The carwash use is compatible with the surrounding commercial land uses, the proximity to the freeway, and is separated from the nearest residentially zoned property to the southeast by 2nd Street. Noise associated with the carwash tunnel and drying vacuums were analyzed in the project’s Mitigated Negative Declaration Addendum, and the stationary noise levels anticipated from the project comply with the City’s stationary noise

standards. Additionally, the site is also located adjacent to State Route 91 where the ambient noise level is elevated due to the number of daily vehicles traveling on the freeway. Therefore, activities associated with the carwash use are not anticipated to be impactful to the nearest residential areas.

FINANCIAL IMPACT:

The applicant paid the application processing fees of $8,722 to cover the cost of the Conditional Use Permit.

ENVIRONMENTAL ANALYSIS:

Pursuant to Section 15164 of the State Guidelines for implementing the California Environmental Quality Act (CEQA), the City has prepared an Addendum to the previously adopted Mitigated Negative Declaration (MND) associated with General Plan Amendment 2023-0004, for the project site. The City has determined that the revised project and the Addendum demonstrate that the environmental analysis, impacts, and mitigation measures identified in the previously adopted MND remain substantively unchanged despite project modifications. The proposed revised project does not raise any new issues or result in impacts not previously analyzed in the prior MND, and none of the conditions described in Section 15162 of the State CEQA Guidelines requiring the preparation of a subsequent MND exist.

PLANNING AND HOUSING COMMISSION ACTION:

At its meeting of September 23, 2024, the Planning and Housing Commission considered the subject matter and took the following action:

Motion was made, seconded (Longwell/Siqueland) and carried, with Vice Chair Vernon absent, that the Planning and Housing Commission adopt the Addendum to the adopted Mitigated Negative Declaration and Mitigation Monitoring Plan, and adopt Resolution No. 2648 GRANTING CUP2024-0006, based on the findings contained in the staff report and conditions of approval. The minutes of the Planning and Housing Commission meeting are included as Exhibit 4.

(Applicant: Greens Development, 16530 Bake Parkway, Suite 200, Irvine, CA 92618)
RECOMMENDED ACTION:

That the Planning and Housing Commission adopt the Addendum to the adopted Mitigated Negative Declaration and Mitigation Monitoring Plan, and adopt Resolution No. 2648 GRANTING CUP2024-0006, based on the findings contained in the staff report and conditions of approval.

BACKGROUND
Greens Development is proposing to develop two adjoining parcels that have a combined acreage of 1.40 acres for commercial purposes. The project site is located on the north side of 2nd Street, west of Buena Vista Avenue, and south of State Route 91 (SR-91). The zoning of the parcels is C-3 (General Commercial). The overall development is being reviewing under Precise Plan 2023-0007 (PP2023-0007). The carwash requires approval of a conditional use permit which is the reason for Conditional Use Permit 2024-0006 (CUP2024-0006).

July 8, 2024 Planning and Housing Commission Meeting
The project was initially proposed for a 1900-square-foot restaurant with drive-through services, gas station with seven double-side fuel pumps (14 total), and a 3,750-square-foot

convenience store. The precise plan (PP2023-0007) was reviewed by the Planning and Housing Commission on July 8, 2024. The Commission raised a number of concerns related to the precise plan and requested additional information from the applicant and staff. The Commission continued the precise plan to the August 12, 2024 Planning and Housing Commission meeting in order to allow the applicant and staff time to address the concerns.

At the August 12, 2024 hearing, the precise plan was continued off calendarin order to allow the applicant and staff more time to address the Commission’s concerns.

Revised Project
Since the initial public hearing, the applicant has made several changes to the project to address some of the concerns raised at the hearing. The key changes involved replacing the 1,900-square-foot restaurant with a self-service carwash facility, reducing the number of gas station fuel pumps from 14 to 10, and reducing the size of the convenience store by 25 square feet. The applicant also revised the project’s sign program, trash enclosure and landscape plan in response to comments received from the Commission. The details of the revisions including the required public improvements related to the development are provided in the staff report for PP2023-0007 for the Commission’s consideration. This CUP staff report focuses on the carwash facility.

PROJECT DESCRIPTION
CUP2024-0006 is for a self-service carwash facility consisting of a 4,110-square-foot automated carwash tunnel and 11 covered self-serve vacuums stalls. The carwash will be maintained and operated by the applicant. The following sections discuss the project’s compliance with the applicable requirements in the CMC.

Site Plan
The carwash facility is proposed on the western portion of the project site. The carwash tunnel is 130 feet long and plotted on the site in a manner where the openings of the tunnel are not directed towards 2nd Street. The drying spaces are located on the south side of the tunnel. The eastern portions of the project site will be developed for a gas station and convenience store. The overall development provides sixteen (16) parking spaces and a trash enclosure which are to be shared among the tenants within the development.

Vehicular access to the site is provided from 2nd Street via two driveways proposed at the site’s south perimeter. The applicant’s site plan is attached as Exhibit 3. A floor plan for the tunnel is attached as Exhibit 5.

The C-3 zone requires a minimum front yard setback of 10 feet along 2nd Street and no setback along the side and rear yards. As designed, the carwash complies with the setback requirements.

Vehicle access into the carwash tunnel is facilitated by a drive-through lane that splits into two lanes at the payment kiosks and merges into a single lane before the entrance into the tunnel. Section 17.76.030 of the CMC requires the carwash drive-through lane to be able to accommodate at least one car before the tunnel and at least six cars from the payment

kiosk. The project’s drive-through lane is designed to accommodate seven cars between the tunnel entrance and payment kiosks, and 12 cars between the payment kiosks and the entrance of the drive-through lane.

The carwash is subject to supplemental standards that are applicable to automotive related uses in Chapter 17.22 of the CMC. These standards ensure that the drive-through lane does not interfere with parking or drive aisles. The carwash facility is located at least 25 feet away from residentially zoned areas, carports for drying areas are constructed of durable materials, and drying areas do not occupy required parking and drive aisles. Additionally, the use of honking horns or other amplified noise is prohibited. The applicant’s plans demonstrate compliance with the supplemental standards, and no amplified noise will be used to notify customers that their car is ready because the facility will be self-served.

Parking
Per the CMC’s Parking Ordinance, Chapter 17.76, the carwash is required to have at least two parking spaces per self-wash stall (tunnel). The overall development requires 16 parking spaces per the requirements in the Parking Ordinance. The site provides 16 spaces plus one loading space for the convenience store. The 16 parking spaces are separate from the 11 vacuum stalls. The project’s required and provided parking is summarized in Table 1.

Elevations
The CMC prescribes no specific architectural style for commercial buildings in the C-3 zone.

The applicant is proposing a contemporary architectural style for the carwash tunnel. The building features tower elements, parapet walls, metal awnings, and glazed storefronts and windows. The buildings’ primary exterior finish is stucco with splitface block and stone veneer as accent materials. The color palette consists of shades of grey and brown with green as an accent color. The rooftops are designed to accommodate mechanical equipment which will be screened from street view behind parapet walls. The vacuum canopies have a matching design to the building. The building is 26 feet in height, which

complies with the CMC’s maximum allowable building height limit of 40 feet for the C-3 zone.

The elevations for the tunnel and vacuum canopies is attached as Exhibit 6 Landscaping
The areas surrounding the carwash site will be landscaped along with the overall commercial development. The landscaping includes a mixture of trees and palms and shrubs which will be installed within planter areas located around the perimeters of the carwash site. The landscape coverage, placement of trees, size of trees at the time of installation, and the use of drought tolerant materials comply with the CMC’s Landscape Ordinance, Chapter 17.70. The conceptual landscape plan is attached as Exhibit 7.

Signage
Per the precise plan, the applicant proposes to construct one 40-foot-tall freeway sign with an electronic message center at the site’s freeway perimeter and one 15-foot-tall pylon sign at the west corner of the site. The carwash will share signage with the overall development.

The signage plan is attached as Exhibit 8. The signage plan is being reviewed under the precise plan and is provided as an exhibit to this CUP staff report for reference only.

ENVIRONMENTAL ANALYSIS
The city approved General Plan Amendment 2023-0004 on August 7, 2024 related to a portion of the project site and adopted a Mitigated Negative Declaration (MND) which was prepared for the original project.

Pursuant to Section 15164 of the State Guidelines for implementing the California Environmental Quality Act (CEQA), the city has prepared an Addendum to the previously adopted MND for the revised project. The city has determined that the revised project and the Addendum demonstrate that the environmental analysis, impacts, and mitigation measures identified in the previously adopted MND remain substantively unchanged despite project modifications. The proposed revised project does not raise any new issues or result in impacts not previously analyzed in the prior MND, and none of the conditions described in Section 15162 of the State CEQA Guidelines requiring the preparation of a subsequent MND exist. The Addendum is attached as Exhibit 9.

FISCAL IMPACT
The applicant has paid the applicable application processing fees for the project.

PUBLIC NOTICE AND COMMENTS
The project was readvertised for the September 23, 2024 Planning and Housing Commission public hearing. A 10-day public notice was mailed to all property owners within a 500-foot radius of the project site, as well as advertised in the Sentinel Weekly News and posted at the project site. As of the preparation of this report, the Planning and Development Department has not received any response regarding the project.

STAFF ANALYSIS
The proposed self-service carwash facility is permitted in the C-3 zone with the approval of a conditional use permit and is consistent with the General Commercial General Plan designation. The project site is capable of accommodating all features associated with the carwash use including the carwash tunnel, drying stalls, landscaped setbacks, parking, trash enclosure, signage. The project complies with the development standards for the C-3 zone and the supplemental standards in Chapter 17.72 of the CMC. Adequate parking is provided based on the CMC requirements for the carwash and overall development.

The carwash use is compatible with the surrounding commercial land uses and is separated from the nearest residentially zoned property to the southeast by 2nd Street. Noise associated with the carwash tunnel and drying vacuums were analyzed in the project’s Mitigated Negative Declaration Addendum (Exhibit 9), and the anticipated noise levels are in compliance with the city’s stationary noise standards for the neighboring land uses. The site is also located adjacent to State Route 91 where the ambient noise level is elevated due to the number of daily vehicles traveling on the freeway. Therefore, activities associated with the carwash use is not anticipated to be impactful to the nearest residential areas.

The Planning and Development Department recommends approval of CUP2024-0006 based on the recommended conditions of approval in Exhibit 4 and the findings of approval below.

FINDINGS OF APPROVAL FOR CUP2024-0006

1. Pursuant to Section 15164 of the State Guidelines for implementing the California Environmental Quality Act (CEQA), the city has prepared an Addendum to the Mitigated Negative Declaration (MND) previously adopted on August 7, 2024 for associated application GPA2023-0004. The city has determined that the proposed revised project and the Addendum demonstrate that the environmental analysis, impacts, and mitigation measures identified in the previously adopted MND remain substantively unchanged despite project modifications. The proposed revised project does not raise any new issues or result in impacts not previously analyzed in the prior MND, and none of the conditions described in Section 15162 of the State CEQA Guidelines requiring the preparation of a subsequent MND exist.

2. All the conditions necessary for granting a Conditional Use Permit as set forth in Section 17.92.110 of the Corona Municipal Code do exist in reference to CUP2024- 0006 for the following reasons:
a. The proposal will not be detrimental to the public health, safety, and convenience or general welfare, and will be in harmony with the various elements and objectives of the city’s General Plan because the project meets or exceeds the development standards for the C-3 zone and provides adequate access from 2nd Street.

b. The proposed use would not be detrimental to other and existing and permitted uses in the general area of the project site because the use would be surrounded by State Route 91 to the north and west, and by 2nd Street to the south and southeast. The site is not immediately adjacent to any sensitive residential land uses. The surrounding commercial uses are compatible with the proposed carwash use. The nearest residentially zoned area is a four-acre vacant property located southeast of the project site, on the other side of 2nd Street. The project is incorporating adequate setbacks, landscaping, and distance as buffers to mitigate noise and protect the privacy of the future residences within the residentially zoned property. Also, the project relates properly to existing streets and highways as it is designed with access from 2nd Street.
c. The proposed use as conditioned complies with the development standards of the C-3 zone which allows carwashes by a conditional use permit.

3. The proposal is consistent with the General Plan for the following reasons:
a. The proposed project implements the General Plan’s General Commercial designation, which allows a range of commercial uses that serve the local neighborhoods, the community and visitors.
b. The overall project including the carwash has a Floor Area Ratio (FAR) of 0.12 which does not exceed the General Plan’s FAR limit of 0.5 established for the General Commercial designation.
c. General Plan Policy LU-5.11 states: Require projects to implement appropriate building orientation, setbacks, buffering, privacy and vehicle access as well as mitigate potential impacts associated with noise and lighting in order to be compatible with adjacent land uses. The project is consistent with Policy LU-5.11 by having the carwash tunnel oriented in a manner that does not have the openings of the tunnel facing directly towards the residentially zoned areas to the southeast of the project site. Additionally, the project provides adequate setback with landscaping from 2nd Street, which also serves as a buffer between the project site and the residentially zoned areas to the southeast.

4. The proposal is consistent with the C-3 zone for the following reasons:
a. The carwash is permitted in the C-3 zone with the approval of a conditional use permit.
b. The carwash and overall project, as designed and conditioned, meets all applicable development standards for the C-3 zone, including setbacks, parking, building height and landscaping coverage.

Pursuant to Section 15164 of the State CEQA (California Environmental Quality Act) Guidelines, the City as the lead agency has reviewed and considered the Addendum to the previously adopted MND, and determined that the environmental analysis, impacts and mitigation requirements identified in the previously adopted MND remain substantively unchanged despite project modifications, the proposed project does not raise any new environmental issues or result in impacts not previously analyzed in the prior MND, and none of the conditions requiring the preparation of a Subsequent MND, as described in Section 15162 of the State CEQA Guidelines, exist.

SECTION 2. Conditional Use Permit Findings. Pursuant to Corona Municipal Code (“CMC”) section 17.92.110 and based on the entire record before the Planning and Housing Commission, including all written and oral evidence presented to the Commission, the Commission hereby makes and adopts the following findings:

1. Pursuant to Section 15164 of the State Guidelines for implementing the California Environmental Quality Act (CEQA), the city has prepared an Addendum to the Mitigated Negative Declaration (MND) previously adopted on August 7, 2024 for associated application GPA2023-0004. The city has determined that the proposed revised project and the Addendum demonstrate that the environmental analysis, impacts, and mitigation measures identified in the previously adopted MND remain substantively unchanged despite project modifications. The proposed revised project does not raise any new issues or result in impacts not previously analyzed in the prior MND, and none of the conditions described in Section 15162 of the State CEQA Guidelines requiring the preparation of a subsequent MND exist.

2. All the conditions necessary for granting a Conditional Use Permit as set forth in Section

17.92.110 of the Corona Municipal Code do exist in reference to CUP2024-0006 for the

RESOLUTION NO. 2648
APPLICATION NO. CUP2024-0006
PAGE | 3
following reasons:
a. The proposal will not be detrimental to the public health, safety, and convenience or general welfare, and will be in harmony with the various elements and objectives of the city’s General Plan because the project meets or exceeds the development standards for the C-3 zone and provides adequate access from 2nd Street. b. The proposed use would not be detrimental to other and existing and permitted uses in the general area of the project site because the use would be surrounded by State Route 91 to the north and west, and by 2nd Street to the south and southeast. The site is not immediately adjacent to any sensitive residential land uses. The surrounding commercial uses are compatible with the proposed carwash use. The nearest residentially zoned area is a four-acre vacant property located southeast of the project site, on the other side of 2nd Street. The project is incorporating adequate setbacks, landscaping, and distance as buffers to mitigate noise and protect the privacy of the future residences within the residentially zoned property.

Also, the project relates properly to existing streets and highways as it is designed with access from 2nd Street.
c. The proposed use as conditioned complies with the development standards of the C3 zone which allows carwashes by a conditional use permit.

3. The proposal is consistent with the General Plan for the following reasons:
a. The proposed project implements the General Plan’s General Commercial designation, which allows a range of commercial uses that serve the local neighborhoods, the community and visitors.
b. The overall project including the carwash has a Floor Area Ratio (FAR) of 0.12 which does not exceed the General Plan’s FAR limit of 0.5 established for the General Commercial designation.
c. General Plan Policy LU-5.11 states: Require projects to implement appropriate building orientation, setbacks, buffering, privacy and vehicle access as well as mitigate potential impacts associated with noise and lighting in order to be compatible with adjacent land uses. The project is consistent with Policy LU-5.11 by having the carwash tunnel oriented in a manner that does not have the openings of the tunnel facing directly towards the residentially zoned areas to the southeast of the project site. Additionally, the project provides adequate setback with landscaping from 2nd Street, which also serves as a buffer between the project site and the residentially zoned areas to the southeast.

4. The proposal is consistent with the C-3 zone for the following reasons:
a. The carwash is permitted in the C-3 zone with the approval of a conditional use permit.
b. The carwash and overall project, as designed and conditioned, meets all applicable

development standards for the C-3 zone, including setbacks, parking, building height and landscaping coverage.

BE IT FURTHER RESOLVED that a copy of this Resolution be delivered to the City Clerk of said City and a copy thereof be sent to the applicant therefore at the address of said applicant as set forth in the application for said Conditional Use Permit.

• Precise Plan 2023-0007 (PP2023-0007) and
• Conditional Use Permit 2024-0006 (CUP2024-0006)
PROJECT LOCATION:

The project site is comprised of two contiguous parcels totaling approximately 1.4 acres, located on the north side of 2nd Street, between the State Route (SR-91) eastbound onramp and Buena Vista Avenue. The assessor’s parcel numbers (APN) are 118-027-54 and 118-027-024.

APPLICANT/PROJECT PROPONENT:

Greens Development Inc.
16530 Bake Parkway, Suite 200
Irvine, CA 92618
BACKGROUND:

The project site is comprised of two remnant parcels that were previously developed prior to the SR-91 widening project occurring in 2016. The western parcel is 0.81 acres and was previously developed for commercial purposes. The eastern parcel is 0.59 acres and was previously developed for residential purposes.

On July 8, 2024, the Corona Planning Commission approved General Plan Amendment 2023-0004 (GPA2023-0004) and Change of Zone 2023-0006 (CZ2023-0006) which were land use applications associated with a proposed commercial project on the project site. The project was for a 1,900-squarePage 832 of 888 PP2023-0007 and CUP2024-0006

foot eating establishment with drive-through services, gas station with seven double-sided pumps (14 pumps total), and a 3,775-square-foot convenience store proposed for project site. The applicant of the project was Greens Development. The project included Precise Plan 2023-0007 (PP202-0007) which was for the review of the site plan, architecture, landscaping, signage and other features of the project.

The Commission continued the precise plan proposed by PP2023-0007 to a future Planning and Housing Commission meeting date to allow the applicant time to address concerns related to the project’s drive-through use, traffic, signage, trash enclosure design, landscaping, convenience store, onsite circulation and queuing concerns, and the location of an off-site crosswalk that was required to be constructed as part of the project’s development.

On August 7, 2024, the City Council approved GPA2023-0004 and CZ2023-0006 and adopted a mitigated negative declaration (MND) which was prepared for the project pursuant to the California Environmental Quality Act (CEQA).

Since the adoption of the MND, the applicant has made revisions to the project in response to the public comments that were received at the July 8, 2024 Planning and Housing Commission meeting.

The applicant replaced the eating establishment with a 4,110-square-foot automated carwash tunnel with 11 vacuum stalls, reduced the number of fueling pumps associated with the gas station from 14 to 10 pumps, and reduced the size of the convenience store from 3,775 to 3,725 square feet. The original and modified project are summarized in Table 1 below.

In accordance with CEQA Guidelines Section 15164, this Mitigated Negative Declaration Addendum (“Addendum”) has been prepared in order to identify any potential environmental impacts from implementation of the Modified Project in the City of Corona. The City of Corona is the Lead Agency in the preparation of this Addendum. The City has discretionary authority over the proposed project. The intended use of this document is to identify potential environmental impacts that would occur from implementation of the Modified Project and to provide the basis for input from public agencies, organizations and interested members of the public.

BASIS OF THE ADDENDUM:

CEQA Guidelines Section 15164 allows for the preparation of an Addendum to an adopted MND if “some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent Environmental Impact Report (or MND) have occurred.” CEQA Guidelines Section 15164 identifies the following conditions that would require the preparation of a subsequent MND:
• Substantial changes in the project are proposed which require major revisions to the MND due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects.
• Substantial changes occur with respect to the circumstances under which the project is

PP2023-0007 and CUP2024-0006
City of Corona 4 Environmental Checklist

undertaken which require major revisions to the MND due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects.

New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time of MND adoption, shows any of the following:
• The project would have one or more significant effects not discussed in the MND. The project would result in impacts substantially more severe than those disclosed in the MND.

Mitigation measures or alternatives previously found not to be feasible would in fact be feasible and would substantially reduce one or more significant effects of the project, but the project proponent declines to adopt the mitigation measure or alternative. • Mitigation measures or alternatives that are considerably different from those analyzed in the MND would substantially reduce one or more significant effects on the environment, but the project proponent declines to adopt the mitigation measure or alternative.

The Addendum need not be circulated for public review (CEQA Guidelines Section 15164[c]); however, an Addendum must be considered by the decision-making body prior to making a decision on the project (CEQA Guidelines Section 15164[d]). This Addendum to the previously adopted MND demonstrates that the environmental analysis, impacts, and mitigation requirements identified in the previously approved MND remains substantively unchanged despite minor project refinements described herein and supports the finding that the proposed project does not raise any new issues and does not exceed the level of impacts identified in the previously approved MND.

PREVIOUSLY APPROVED EXISTING MITIGATION MEASURES:

Below is a listing of mitigation measures provided in the previously approved MND that are relevant to the proposed Modified Project.

MM CUL-1 Archaeological Monitoring. Prior to the issuance of a grading permit, the Project Applicant shall retain and enter a monitoring and mitigation service contract with a qualified Archaeologist (“Archaeological Monitor”) for mitigation monitoring services and implement a Cultural Resource Monitoring Program (CRMP). At least 30 days prior to issuance of grading permits, a copy of the executed agreement between the Project Applicant and Archaeologist shall be submitted to the Planning and Development Department:
• A CRMP shall be prepared to guide the procedures and protocols of an archaeological mitigation monitoring program that shall be implemented during initial onsite and offsite ground disturbing activities. The CRMP shall include, but not be limited to, the Project grading and development schedule; approved Project cultural resources mitigation measures and conditions of approval; monitoring procedures; protocols for the identification, assessment, collection, and analysis of any resource(s) observed during grading; curation guidelines; and coordination with project personnel, City staff, and any participating Native American tribe(s). The Rincon Band of Luiseño Indians shall be notified of any discoveries. The final CRMP shall be submitted to the City Project planner and/or inspector, the appropriate Project supervisor/engineer/etc., and monitoring Native American tribe(s), if any. • The Archaeological Monitor shall be invited to a preconstruction meeting with construction personnel and City and tribal representatives. The attending archaeologist shall review the provisions of the CRMP and answer any

PP2023-0007 and CUP2024-0006
City of Corona 5 Environmental Checklist

applicable questions.
• Full-time monitoring shall occur throughout the entire Project area, including all off-site improvement areas, during initial ground-disturbing activities. Fulltime monitoring shall continue until the Archaeological Monitor determines that the overall sensitivity of the Project area is low as a result of mitigation monitoring and shall have the authority to modify and reduce the monitoring program to either periodic spot-checks or complete suspension of the monitoring program. Should the monitor(s) determine that there are no cultural resources within the Project site or off-site improvement areas, or should the sensitivity be reduced to low during monitoring, all monitoring shall cease.

MM CUL-2 Inadvertent Discovery and Native American Notification. In the event that a significant cultural resource is discovered during ground disturbance activities, the project archaeologist shall notify the City and the Rincon Band of Luiseño Indians for purposes of inviting the Tribe to participate in the CRMP implementation and to observe any continuing ground-disturbing construction activities. Further, all ground disturbance activities within 50 feet of the discovered cultural resource shall be halted and the applicant and a meeting shall be convened between the developer, the consulting archaeologist, the lead agency and a Rincon tribal representative to discuss the significance of the find. Further ground disturbance shall not resume in the area of the discovery until the appropriate treatment has been accomplished.

MM CUL-3 Paleontological Monitor. Prior to the issuance of grading permits, the Project Applicant shall submit to and receive approval from the City of a Paleontological Resources Monitoring and Mitigation Plan (PRMMP). The PRMMP shall include the provision of a trained paleontological monitor during onsite soil disturbance activities.

The monitoring for paleontological resources shall be conducted on a full-time basis during the rough grading phases of the Project site within native soils that have the potential to harbor paleontological resources. The paleontological monitor shall be equipped to rapidly remove any large fossil specimens encountered during excavation. During monitoring, samples of soil shall be collected and processed to recover micro-vertebrate fossils. Processing shall include wet screen washing and microscopic examination of the residual materials to identify small vertebrate remains. If paleontological resources are unearthed or discovered during grading activities, the following recovery processes shall apply:
• Upon encountering a large deposit of bone, salvage of all bone in the area shall be conducted with additional field staff and in accordance with modern paleontological techniques.
• All fossils collected during the project shall be prepared to a reasonable point of identification. Excess sediment or matrix shall be removed from the specimens to reduce the bulk and cost of storage. Itemized catalogs of all material collected and identified shall be provided to the museum repository along with the specimens.
• A report documenting the results of the monitoring and salvage activities and the significance of the fossils shall be prepared.
• All fossils collected during this work, along with the itemized inventory of these specimens, shall be deposited in a museum repository (such as the

PP2023-0007 and CUP2024-0006
City of Corona 6 Environmental Checklist

Western Science Center for Archaeology & Paleontology, the Riverside Metropolitan Museum, or the San Bernardino County Museum) for permanent curation and storage.

MM CUL-4 Discovery of Human Remains: In the event that human remains (or remains that may be human) are discovered at the project site during grading or earthmoving activities, the construction contractors, project archaeologist, and/or designated Native American Monitor shall immediately stop all activities within 100 feet of the find. The project proponent shall then inform the Riverside County Coroner and the City of Corona Planning and Development Department, Planning Division, immediately, and the coroner shall be permitted to examine the remains as required by California Health and Safety Code Section 7050.5(b). Section 7050.5 requires that excavation be stopped in the vicinity of discovered human remains until the coroner can determine whether the remains are those of a Native American. If human remains are determined as those of Native American origin, the applicant shall comply with the state relating to the disposition of Native American burials that fall within the jurisdiction of the Native American Heritage Commission (PRC Section 5097). The coroner shall contact the Native American Heritage Commission (NAHC) to determine the most likely descendant(s) (MLD). The MLD shall complete his or her inspection and make recommendations or preferences for treatment within 48 hours of being granted access to the site. The Disposition of the remains shall be overseen by the most likely descendant(s) to determine the most appropriate means of treating the human remains and any associated grave artifacts.

The specific locations of Native American burials and reburials will be proprietary and not disclosed to the general public. The locations will be documented by the consulting archaeologist in conjunction with the various stakeholders and a report of findings will be filed with the Eastern Information Center (EIC).According to California Health and Safety Code, six or more human burials at one location constitute a cemetery (Section 8100), and disturbance of Native American cemeteries is a felony (Section 7052) determined in consultation between the project proponent and the MLD. In the event that the project proponent and the MLD are in disagreement regarding the disposition of the remains, State law will apply and the median and decision process will occur with the Native American Heritage Commission (see Public Resources Code Section 5097.98(e) and 5097.94(k)).

PROJECT DESCRIPTION FOR MODIFIED PROJECT:

The Modified Project is a commercial development proposed on two vacant contiguous parcels totaling approximately 1.4 acres, located on the north side of 2nd Street, approximately 450 feet west of Buena Vista Avenue. The site borders the south side of State Route 91 (SR-91). The assessor’s parcel numbers are 118-027-54 and 118-027-024.

The Project proposes three detached commercial structures with the following uses:
• 4,110-square-foot automated carwash tunnel with a drive-through lane with 11 vacuum stalls, • Gas station with an approximate 4,000-squarae-foot canopy with five double-sided pumps (10 vehicle fueling positions), and
• 3,725-square-foot convenience store.

The Project requires and provides 16 parking spaces on-site, plus a loading space, trash enclosure, and signage. Vehicle access to the project site is provided from 2 nd Street via two driveways proposed
at the site’s south perimeter.

PP2023-0007 and CUP2024-0006
City of Corona 7 Environmental Checklist

Figure 2: Site Plan of Modified Project
The overall site plan, architecture, landscaping and other features of the development require the approval of a precise plan. The carwash requires the approval of a conditional use permit. The entitlements which the applicant is seeking approval for include:
• Precise Plan 2023-0007 and
• Conditional Use Permit 2024-0006.

With development of the Modified Project, the applicant is required to construct two raised medians on 2 nd Street along the Project frontage to facilitate site access for east bound traffic. Due to the raised medians, the west project driveway will be restricted to right-in and right-out turn movements. The east project driveway will have full turn movements. In addition, the applicant is required to construct the missing public improvements along the Modified Project frontage adjacent to 2nd Street which include the construction of the missing roadway pavement, curb and gutter, and a six-foot wide sidewalk on the north half of 2nd Street. The Modified Project is also required to construct a pedestrian crosswalk at the intersection of 2nd Street and the SR-91 eastbound on-ramp. This will require coordination between the applicant and Caltrans to ensure that the crosswalk does not conflict with Caltrans traffic signals at this intersection. As an alternative, should Caltrans not permit the crosswalk, the applicant will be required to construct a sidewalk along the north side of 2nd Street from the project’s eastern limits to Buena Vista Avenue.

Per the City’s General Plan, the project site is zoned C-3 (General Commercial) and has a General Plan land use designation of General Commercial (GC). The zoning and General Plan designation permit the proposed commercial use.

ENVIRONMENTAL SETTING:

CEQA Guidelines §15125 establishes requirements for defining the environmental setting to which the environmental effects of a proposed project must be compared. The environmental setting is defined as “…the physical environmental conditions in the vicinity of the project, as they exist at the time the

PP2023-0007 and CUP2024-0006
City of Corona 8 Environmental Checklist

Notice of Preparation is published, or if no Notice of Preparation is published, at the time the environmental analysis is commenced…” (CEQA Guidelines §15125[a]). Because a Notice of Preparation was not required, the environmental setting for the Project is April 11, 2024, which is the date that the Project’s environmental analysis commenced.

Site Description: The project site’s prior uses included an automobile dealership and a mobile home park which were demolished prior to the SR-91 expansion project in 2016. In recent years, the site has been used for soil and equipment storage for construction. The project site was previously graded with a minor slope on the north side of the site, on-site elevations range from 650 feet in the west to 640 feet in the east. The remainder of the site is relatively flat and characterized as disturbed with ruderal plants. The site drains towards 2nd Street.

Site Surroundings: The project site is located on the north side of 2nd Street; it is the only property between Buena Vista Avenue and SR-91 eastbound on-ramp. SR-91 abuts the project site to the north, and beyond the SR-91 to the north are commercial uses and a mobile home park. To the west is the SR-91 on- and off-ramps. To the east is Buena Vista Avenue with multiple family residential uses beyond. To the southeast across 2nd Street is a vacant property zoned R-3. To the southwest across 2 nd Street is a commercial retail center zoned C-3. Table 1 shows the on-site and adjacent land uses, General Plan land use designations, and zoning classifications.

GENERAL PLAN \ ZONING:

Per the city’s zoning map and General Plan land use map, the project site is zoned C-3 (General Commercial) and has a General Plan land use designation of General Commercial (GC), respectively.

The C-3 zone permits the proposed gas station and convenience store by right and requires the approval of a precise plan. A separate approval of a conditional use permit is required for the carwash.

The GC designation permits a range of commercial uses that serve local neighborhoods, the community and visitors. The proposed uses are local serving uses that support the community and visitors alike. Therefore, the project is consistent with the city’s zoning and General Plan. Refer to Figures 3A and 3B.

OTHER PUBLIC AGENCIES WHOSE APPROVAL IS REQUIRED
The Project requires the approval from the following agencies:
• Santa Ana Regional Water Quality Control Board (National Pollutant Discharge Elimination System Permit and Report of Waste Discharge, California Construction General Permit and California Industrial General Permit)
• Caltrans (Encroachment Permit)
STAFF RECOMMENDATION:

The City's Staff, having undertaken and completed an initial study of this project in accordance with the City's "Local Guidelines for Implementing the California Environmental Quality Act (CEQA)", has concluded and recommends the following:

The proposed project could not have a significant effect on the environment. Therefore, a NEGATIVE DECLARATION will be prepared.
__ The proposed project could have a significant effect on the environment, however, the potentially significant effects have been analyzed and mitigated to below a level of significance pursuant to a previous EIR as identified in the Environmental Checklist attached. Therefore, a NEGATIVE DECLARATION WILL BE PREPARED.

X The Initial Study identified potentially significant effects on the environment but revisions in the project plans or proposals made by or agreed to by the applicant would avoid or mitigate the effects to below a level of significance. Therefore, an ADDENDUM TO THE PREVIOUSLY ADOPTED MITIGATED NEGATIVE DECLARATION will be prepared.

The proposed project may have a significant effect on the environment. Therefore, an ENVIRONMENTAL IMPACT REPORT is required.
__ The proposed project may have a significant effect on the environment, however, a previous EIR has addressed only a portion of the effects identified as described in the Environmental Checklist discussion. As there are potentially significant effects that have not been mitigated to below significant levels, a FOCUSED EIR will be prepared to evaluate only these effects.

There is no evidence that the proposed project will have the potential for adverse effect on fish and wildlife resources, as defined in Section 711.2 of the Fish and Game Code.

Impact No Impact
a. Conflict with any land use plan/policy or agency regulation (general plan, specific plan, zoning)
b. Conflict with surrounding land uses
c. Physically divide established community
Discussion:
a.

Previous Adopted MND Finding – No Impact: The previous MND found that the original project would not conflict with the land use plans or policies because the zoning and General Plan designation of the project would permit the proposed commercial uses for the project site.

Addendum Finding – No Impact: The Modified Project would not result in any conflicts with the city’s land use plan or policies because the proposed land uses are permitted by right in the C-3 zone and GC General Plan land use designation.

Specifically, the C-3 zone permits the proposed gas station and convenience store by right and requires the review of a precise plan for these types of uses. A separate approval of a conditional use permit is required for the carwash. The GC designation permits a range of commercial uses that serve local neighborhoods, the community and visitors. The proposed uses, including the new carwash, are local serving uses that support the community and visitors alike. Therefore, the Modified Project would not conflict with the city’s land use plans or policies. No impact would occur. b.

Previous Adopted MND Finding – No Impact: The previous MND found that the original project would not conflict with the surrounding land uses because the project site is located adjacent to the eastbound SR-91 and is near general commercial uses. Furthermore, the existing residential uses located to the east and north are buffered by Buena Vista Avenue and the SR-91, respectively.

Addendum Finding – No Impact: Implementation of the Modified Project would not result in conflicts with the surrounding land uses because the proposed land use remains commercial as previously analyzed in the prior MND. The surrounding land uses consists of commercial and residential uses. Furthermore, the existing residential uses located to the east and north are buffered by Buena Vista Avenue and the SR-91, respectively. No impact would occur. c.

Previous Adopted MND Finding – No Impact: The previous MND found that the original project would not physically divide the established neighborhood because the project site is located on a vacate site adjacent to the SR-91 and is separated from the surrounding developments by 2nd Street, Buena Vista Avenue and the SR-91 on- and off-ramps. As such, no impacts would occur.

Addendum Finding – No Impact: Implementation of the Modified Project would not increase the potential to physically divide the established neighborhood because the Modified Project is proposed on the same project site that was previously analysis.

Therefore, no impacts would occur.

Previous Adopted MND Finding – No Impact: The previous MND found that the project would not induce substantial growth, nor would it displace substantial numbers of existing housing or people because the project site is vacant and is proposed for commercial purposes. Therefore, no impact would occur.

Addendum Finding – No Impact: The project site continues to be vacant and the proposed land use associated with the Modified Project continues to remain commercial. Therefore, the Modified Project would not induce substantial growth or displace substantial numbers of existing housing or people. No impacts would occur. b.

f. Expansive soils
Discussion:
a.

Previous Adopted MND Finding – No Impact: Per the previous adopted MND, there are no known active faults crossing or projecting through the site. The site is not located in an Alquist-Priolo earthquake fault zone and thus, ground rupture due to faulting is considered unlikely at this site. The project will be subject to city and county local codes, the latest California Building Code (CBC). Therefore, any potential impacts related to fault/seismic failures would be reduced to less than significant impact and no further mitigation would be necessary.

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 14 Environmental Checklist

Addendum Finding – No Impact: The Modified Project would be subject to the same city and county local codes, the latest California Building Code (CBC). Therefore, any potential impacts related to fault/seismic failures would be reduced to less than significant impact and no further mitigation would be necessary. The original “no impact” finding remains unchanged. b.

Previous Adopted MND Finding – Less Than Significant: Per the previous adopted MND, the project would involve grading more than 100 cubic yards. According to the project’s engineer design team, grading on the project site would cut approximately 3,400 cubic yards, while fill would be approximately 500 cubic yards. The applicant is required to comply with the recommendations and guidelines provided in the Geotechnical Investigation (Sladden Engineering, dated December 2021). The applicant is required to adhere to the city's grading regulations, ordinances and the grading specifications identified in the soil investigation report to reduce any impacts associated with the grading process, such as frequent watering of the site and cleaning of haul roads. The applicant's compliance with the above requirements will be ensured upon obtaining grading permits from the city’s Development Services Division, thereby resulting in a less than significant impact and, therefore, no additional mitigation would be required.

Addendum Finding – Less Than Significant: The Modified Project would involve grading more than 100 cubic yards and thus, be subject to the same the recommendations and guidelines provided in the Geotechnical Investigation (Sladden Engineering, dated December 2021) and be required to adhere to the city's grading regulations, ordinances and the grading specifications identified in the soil investigation report to reduce any impacts associated with the grading process. Therefore, impacts associated with the Modified Project would continue to be less than significant as previously found. c.

Previous Adopted MND Finding – No Impact: The previous adopted MND determined that the project would not result in any impacts related to grading of over 10% slopes because the project site is located in an area containing relatively flat terrain.

Addendum Finding – No Impact: The “no impact” finding remains unchanged for the Modified Project because there have been no changes to the project site which remains relatively flat terrain. d.

Previous Adopted MND Finding – No Impact: The previous adopted MND determined that the project would not result in any impacts related to erosion because the project would be subject to the city’s grading regulations established in the Corona Municipal Code as well as a National Pollutant Discharge Elimination System (NPDES) permit and a Storm Water Pollution Prevention Plan (SWPPP) which would be required to address erosion and discharge impacts associated with the proposed on-site grading. Additionally, the project is required to submit a final Water Quality Management Plan (WQMP) which would identify measures to treat and/or limit the entry of contaminants into the storm drain system.

Addendum Finding – No Impact: The “no impact” finding remains unchanged for the Modified Project because the Modified Project continues to be subject to the same requirements to address soil erosion. e.

See discussion under Section 3d.
f.

Previous Adopted MND Finding – No Impact: The previous adopted MND determined that the project would not result in impacts related to expansive soils, because based on laboratory classification and testing by Sladden Engineering (Geotechnical Investigation report, dated December 2021), the soil onsite is expected to have a low expansion potential.

Therefore, no further mitigation is warranted with respect to expansive soils.

Addendum Finding – No Impact: Implementation of the Modified Project would not change the original “no impact” finding because the Modified Project is proposed on the same site that was previously analyzed. There is no expansion proposed to the project site that would require additional soils analysis.

Previous Adopted MND Finding – Less than Significant Impact: The previous MND found that the project would result in a less than significant impact as it relates to violating water quality standards/waste discharge requirements, depleting ground water supplies altering the existing drainage patterns, increasing flooding hazards, degrading the surface or groundwater quality, and exceeding capacity of storm water drainage systems.

Addendum Finding – Less than Significant Impact: The Modified Project is proposed on the same site that was previously analyzed and the proposed use remains commercial. There is no expansion to the project site that requires additional analysis. Therefore, implementation of the Modified Project would result in the same level of impact to these areas of concern. f and g.

Previous Adopted MND Finding – No Impact: The previous MND determined that the project would result in no impacts as it relates to flooding. AccordingtotheFederalEmergencyManagementAgency(FEMA)FloodInsuranceRateMaps(FIRMS),the project site is not within the 100-year or 500-year flood hazard areas. Development of the project site will not result in a flooding hazard, nor will it expose the site and surrounding area to flooding.

Addendum Finding – No Impact: The Modified Project is proposed on the same site that was previously analyzed . There is no expansion to the project site that requires additional analysis. Therefore, implementation of the Modified Project would result in the same level of impact to these areas of concern.

Previous Adopted MND Finding – No Impact: The previous MND determined that the project would not conflict with the South Coast Air Quality Management District’s (SCAQMD) Air Quality Management Plan.

Addendum Finding – No Impact: Per the project’s updated C-Store Gas Station Air Quality, Global Climate Change, and Energy Impact Analysis (Gaddini Group, dated July 26, 2024), the Modified Project would not conflict with SCAQMD’s Air Quality Management Plan. The project would comply with all applicable SCAQMD construction-source emission reduction rules and guidelines. For localized emissions, the project would not exceed applicable localized significance thresholds (LSTs) established by the SCAQMD. Therefore, implementation of the Modified Project would result in no impacts. b and c.

Previous Adopted MND Finding – Less Than Significant Impact: The previous MND determined that the project would result in a less than significant regional construction and operational related air quality impacts.

Addendum Finding – Less Than Significant Impact: Per the project’s updated C-Store Gas Station Air Quality, Global Climate Change, and Energy Impact Analysis (Gaddini Group, dated July 26, 2024), none of the Modified Project’s construction and operation related emissions would exceed the regional thresholds established by the SCAQMD.

Therefore, implementation of the Modified Project would result in a less than significant impact. The project’s construction and operational related pollutant emissions impacts are summarized in Tables 5-A and 5-B.

Previous Adopted MND Finding – Less Than Significant Impact: The previous MND determined that the project would not result in the exposure of sensitive receptors to pollutants. The nearest sensitive receptors near the project site include multiple family residential uses located approximately 460 feet southeast, 570 feet south, and 781 feet west; a mobile home park located approximately 327 feet southwest and 315 feet north; a high school located approximately 327 feet southeast, and a transient lodging use (motel) located approximately 645 feet west of the project site. Per the air quality analysis, none of the analyzed criteria pollutants would exceed the local emissions thresholds at the nearest sensitive receptors. Therefore, a less than significant impact would occur and no mitigation was warranted.

Addendum Finding – Less Than Significant Impact: The proposed Modified Project would not expose sensitive receptors to pollutants because the Modified Project would be subject to the same rules and regulations established by the SCAQMD during the construction phase of the project. Also, the Modified Project’s pollutant emissions would not exceed the established regional pollutant emissions thresholds during the construction and operational phase of the Modified Project, as shown in Tables 5-A and 5-B. Therefore, impacts would be less than signific e.

Previous Adopted MND Finding – No Impact: The previous MND determined that the project’s short-term (construction) and long-term (operational) activities would result in no odor impacts.

Addendum Finding – Less Than Significant Impact: The Modified Project does not contain land uses typically associated with emitting objectionable odors. Potential odor sources associated with the proposed Project may result from construction equipment exhaust and the application of asphalt and architectural coatings during construction activities and the temporary storage of typical solid waste (refuse) associated with the proposed Modified Project’s (long-term operational) uses. Standard construction requirements would minimize odor impacts from construction. The construction odor emissions would be temporary, short-term, and intermittent in nature and would cease upon completion of the respective phase of construction and is thus considered less than significant. It is expected that Modified Project-generated refuse would be stored in covered containers and removed at regular intervals in compliance with the solid waste regulations. The proposed Project would also be required to comply with SCAQMD Rule 402 to prevent occurrences of public nuisances. Therefore, odors associated with the proposed Project construction and operations would be less than significant and no mitigation is required.

Discussion:

The following discussions contain information on the original traffic study that was prepared for the original project to provide background information and context for the Modified Project. An updated analysis was prepared for the Modified Project which is also discussed in this section.

Original Project Traffic Impact Analysis
A Traffic Impact Analysis (TIA) was prepared for the original project by Trames Solutions, Inc. (dated July 28, 2023, revised March 18, 2024) to evaluate the traffic impacts of the original project. Figure 5 shows the study areas that were included in the TIA. The study areas included the following:

1. Lincoln Avenue / Pomona Road

2. Lincoln Avenue / SR-91 Westbound On & Off Ramps

3. Lincoln Avenue / D Street – 2
nd Street

4. Lincoln Avenue / 6th Street

5. SR-91 Eastbound On & Off Ramps / 2nd Street

6. Buena Vista Avenue / 2nd Street

7. Cardena Driveway – Project Driveway #1 / 2nd Street

8. Project Driveway #2 / 2nd Street
In addition, three freeway segments on the SR-91 eastbound and westbound lanes:

1. SR-91 Westbound, east of Lincoln Avenue

2. SR-91 Westbound, between Ramps

3. SR-91 Westbound, west of Lincoln Avenue

4. SR-91 Eastbound, west of Lincoln Avenue

5. SR-91 Eastbound, between Ramps

Figure 4 shows the site plan for the Project. Project Driveway #1 is the west driveway and is restricted to right-in and right-out turn movements due to a required raised median that will be constructed in 2nd Street in front of the project frontage. Project Driveway #2 is the east driveway and will allow for full-turn movements.

Project Traffic Generation: The original project is anticipated to generate approximately 2,077 total average daily trips, with 127 trips during the AM peak hour and 145 trips during the PM peak hour. Table 6-A summarizes the original project’s trip generation.

Table 6-A: Project Trip Generation Summary
Cumulative Trip Generation (Project Plus Planned Developments): Other recently approved projects or projects that are pending approval by the City that are located in the vicinity of the project site were also analyzed with the Project to determine a cumulative generation of vehicle trips. The cumulative developments are projected to generate a total of approximately 7,984 trips per day with 712 trips during the AM peak hour and 903 trips during the PM peak hour. Table 6-B show the cumulative trip generation results.

Table 6-B: Cumulative Trip Generation Summary

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 22 Environmental Checklist

Existing Traffic Conditions For Study Areas: The City of Corona considers a Level of Service (LOS) D or above as acceptable. All study intersections are currently operating at a Level of Service (LOS) C or above in the AM and PM peak hours. The study freeway ramps are operating at an acceptable LOS D or better during the peak hours. The TIA also analyzed three freeway segments on the SR-91 eastbound and westbound lanes. All study freeway segments are operating at an acceptable LOS D or above.

Existing Traffic Conditions Plus Project Traffic: The existing traffic conditions for the study intersections plus the original project traffic are anticipated to operate at an acceptable LOS D or above during the peak hours. The existing traffic conditions for the study freeway ramps plus the original project traffic are anticipated to operate at an acceptable LOS D or above during the peak hours. The study freeway segments plus the original project traffic are anticipated to operate at an acceptable LOS Dor above during the peak hours.

Existing Traffic Conditions Plus Ambient Growth And Project Traffic: A 2% ambient growth rate was used in the TIA to account for traffic not attributed to the original project or other planned developments within the study area. With the ambient growth rate factored into the analysis, all study intersections, freeway ramps and freeway segments plus the original project traffic are anticipated to generate an LOS D or above during the AM and PM peak hours.

Existing Traffic Conditions Plus Ambient Growth, Project Traffic, And Cumulative Traffic: The existing traffic conditions for the study intersections plus ambient growth, original project traffic and cumulative traffic are anticipated to operate at an acceptable LOS D or above during the peak hours. The existing traffic conditions for the study freeway ramps plus original project traffic and cumulative traffic are anticipated to operate at an acceptable LOS D or above during the peak hours. The study freeway segments plus original project traffic and cumulative traffic are anticipated to operate at an acceptable LOS Dor above during the peak hours.

No Project Condition At Buildout (2040): Under the 2040 No Project Condition, the study intersections, freeway ramps and freeway segments are projected to operate at an acceptable LOS D or above. 2040 With Original Project Traffic Condition At Buildout (2040): Under the 2040 With Project Traffic Condition, the study intersections, freeway ramps and freeway segments plus the Project traffic are projected to operate at an acceptable LOS D or above.

For 2040 With Original Project Conditions, the intersection at Project Driveway #2 and 2nd Street is projected to meet traffic signal warrants. However, due to intersection spacing considerations, the TIA recommends that this intersection be stop signed controlled since it is anticipated to operate at an acceptable LOS D or above as a cross-street stop-controlled intersection. Additional discussions regarding this recommendation and other circulation and vehicular stacking recommendations are provided in Section 6f.

Modified Project Traffic Impact Analysis
A supplemental Corona C-Store Trip Generation/Pedestrian Access Evaluation was prepared by Trames Solutions (dated September 5, 2024) to evaluate the Modified Project. The proposed Modified Project with the carwash and fewer fueling positions would generate 413 fewer trips per day, with 67 fewer trips in the AM peak hour and 14 fewer trips in the PM peak hour.

Trames Solutions also evaluated three potential crosswalk locations on 2nd Street to provide pedestrian access to the project site. These included the following:
• Option 1 – Sidewalk to Buena Vista Avenue
• Option 2 – Mid-Block Crossing on 2nd Street
• Option 3 (original option) – 2
nd Street/SR-91
Under Option 1, a sidewalk would be constructed between the project site and Buena Vista Avenue to the east. This would allow pedestrians to use the existing crosswalk at the existing stop-controlled intersection at 2nd Street/Buena Vista Avenue and access the project site on the north side of 2nd Street. Trames Solutions recommended this solution as it would allow for a safer crossing of 2nd Street for pedestrians to access the site because vehicles would be stopped at the intersection to allow pedestrians to cross the street.

Under Option 2, an uncontrolled painted/lighted crosswalk on 2nd Street between the project site and Buena Vista Avenue would be installed to allow pedestrians to cross 2nd Street in an uncontrolled, marked crosswalk. Trames Solutions did not recommend this option because it would provide a false sense of security for pedestrians to believe that an oncoming vehicle

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 23 Environmental Checklist

will stop. The distance between the SR-91 on/off ramp and Buena Vista Avenue is about 1,100 feet. Since the crossing would be located between these two intersections, the relatively short distance to either intersection may not allow appropriate time for pedestrians to cross. Furthermore, a horizontal curve along 2nd Street exists in the vicinity of the crossing area and could reduce the visibility of drivers to pedestrians.

Option 3 was originally required by the city for the original project and evaluated in the prior MND. The applicant is in discussions with Caltrans to determine the feasibility of having this crosswalk in their facility. This crosswalk remains as a condition of approval with Option 1 as an alternative location for pedestrians to access the site.

Table 6-C: Project Trip Generation Summary
a.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not conflict with programs, plans, or ordinances that support transit services, bicycle lanes, sidewalks, and trails, because the required street improvements for 2nd Street associated with the original project would be designed in accordance with all applicable engineering standards relating to vehicle traffic, bicycles, pedestrian safety, line of site, and other design criteria. Furthermore, the Project is not proposing any improvements that would conflict with the existing public transit service lines in the immediate vicinity or any future transit route in the area. Therefore, the original project would not conflict with programs, plans or ordinances that support the City’s transit services.

Addendum Finding – No Impact: A Corona C-Store Trip Generation/Pedestrian Access Evaluation was prepared by Trames Solutions (dated September 5, 2024) to evaluate the revisions made the project (i.e., Modified Project). The Modified Project would be subject to the same roadway improvements on 2nd Street that were originally required for the original project.

Therefore, the level of impact would remain the same as previously identified in the adopted MND. Therefore, no additional mitigation is required.
b.

Previous Adopted MND Finding – No Impact: Senate Bill (SB) 743 was signed by Governor Brown in 2013 and required the Governor’s Office of Planning and Research (OPR) to amend the CEQA Guidelines to provide an alternative to LOS for evaluating transportation impacts. SB 743 specified that the new criteria should promote the reduction of GHG emissions, the development of multimodal transportation networks and a diversity of land uses. In response, Section 15064.3 was added to the CEQA Guidelines that became effective on July 1, 2020, and requires that Vehicle Miles Traveled (VMT) be evaluated for impacts and provides lead agencies with the discretion to choose the most appropriate methodology and thresholds for its evaluation.

The City of Corona Vehicle Miles Traveled (VMT) Analysis Guidelines lists screening thresholds to determine if land use projects would require a VMT assessment. The City’s Guidelines also provide criteria for projects that could screen out of further analysis and would be considered to have a less-than significant impact on VMT. If a Project meets one of the criteria

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 24 Environmental Checklist

below, it is considered to have a less than significant impact on VMT and does not require further analysis.

1. The Project serves the local community.

2. The Project is located within a Transit Priority Area (TPA).

3. The Project is located in a low VMT generating VMT generating model traffic analysis zones (TAZs).

Based on the Governor’s Office of Planning and Research (OPR) Technical Advisory on Evaluating Transportation Impacts in CEQA (OPR, December 2018), Screening Criteria 1 includes a local serving retail projects of up to 50,000; Screening Criteria 2 is defined as a ½ mile radius around an existing or planned major transit stop or an existing stop along a high quality transit corridor. The City’s TPA, as determined by the Southern California Association of Governments (SCAG), consists of approximately ½ mile measured along both sides of the State Route 91.

The prior MND determined that the original project meets Screening Criteria 1 and 2, because the Project’s total floor area is only 5,650 square feet and the project site is located within the City’s TPA. As such, a VMT analysis was not required for the original project, as the Projects’ VMT impacts are presumably less than significant. Therefore, no mitigation was warranted.

Addendum Finding – No Impact: The Modified Project meets the Screening Criteria 1 and 2, because the Modified Project’s total floor area is less than 50,000 square feet and the project site is located within the City’s TPA. As such, a VMT analysis was not required as the Modified Projects’ VMT impacts are presumably less than significant. c
Previous Adopted MND Finding – Less Than Significant Impact: As discussed in Section 6b, the City of Corona Vehicle Miles Traveled (VMT) Analysis Guidelines lists screening thresholds to determine if land use projects would require a VMT assessment. The City’s Guidelines also provide criteria for projects that could screen out of further analysis and would be considered to have a less-than significant impact on VMT. The original project is located within a TPA and would serve the local community; thus the original project did not require further VMT analysis. As such, impacts related to VMT, including total daily VMT per service population, would be less than significant and no mitigation was warranted.

Addendum Finding – Less Than Significant Impact: As previously discussed, the Modified Project meets the Screening Criteria 1 and 2, because the Modified Project’s total floor area is less than 50,000 square feet and the project site is located within the City’s TPA. As such, a VMT analysis was not required as the Modified Projects’ VMT impacts are presumably less than significant.

See discussion under 6c.
e.

Previous Adopted MND Finding – No Impact: The closest airport is Corona Municipal Airport which is approximately 1.3 miles northwest of the project site. As illustrated in the Riverside County Airport Land Use Compatibility Plan for Corona Municipal Airport, the project site is not located within any land use compatibility zones. As such, the prior MND determined that the original project would not obstruct or change air traffic patterns. There would be no impacts, and thus, no mitigation was warranted.

Addendum Finding – No Impact: The level impact in this area remains the same as originally identified in the prior MND for the Modified Project because the project site has not changed and continues to be outside of any land use compatibility zones.

As such, no impacts are anticipated, and no mitigation is warranted. f.

Previous Adopted MND Finding – Less Than Significant Impact: The design of the original project’s access, internal circulation, and surrounding circulation were reviewed for approval by the City Traffic Engineer for traffic hazards and the Fire Department for adequate fire and emergency access. 2
nd Street is classified by the General Plan as a secondary 4-lane roadway which requires an ultimate right-of-way width of 88 feet, with 64 feet of roadway from curb-to-curb. However, the segment of 2nd Street that abuts the project site will be required to be improved as a modified secondary roadway having an ultimate right-of-way that will vary. The original project did not require additional street dedication; however, the project applicant was required to construct the missing public improvements on the north half of 2nd Street adjacent to the project site which shall include the construction of the missing roadway width, curb and gutter, and a six-foot wide sidewalk. Ultimately, the north half of 2nd Street measured from the street centerline will vary in width from 39 feet to 42 feet.

Additionally, the original project was required to install a pedestrian crosswalk across 2nd Street at the intersection of 2nd Street

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 25 Environmental Checklist

and the SR-91 eastbound on-ramp to provide pedestrian connectivity to and from the Project site. Implementation of the crosswalk would require coordination with Caltrans because it would require a modification to the existing Caltrans traffic signals at this intersection. Should Caltrans deem the crosswalk to not be feasible, the alternative option is for the applicant to provide a sidewalk along the north side of 2nd Street from the easterly limits of the Project frontage to the intersection of 2nd Street and Buena Vista Avenue. This requirement was placed as a condition of approval for the Project’s Conditions of Approval for PP2023-0007. Construction of the pedestrian connectivity would reduce impacts to traffic hazards to less than significant and no mitigation is required.

Furthermore, per the TIA (dated March 18, 2024), at buildout year 2040, the intersection at Project Driveway #2 and 2nd Street was projected to meet traffic signal warrants. However, due to intersection spacing considerations, the TIA recommended that this intersection be stop signed controlled since it is anticipated to operate at an acceptable LOS D or above as a cross-street stop-controlled intersection. The TIA also recommended the following improvements to improve circulation:
• Construct 2nd Street to its ultimate half-section width as a secondary 4-lane roadway from the westerly project boundary to the easterly project boundary.
• Construct a raised median along 2nd Steet from the SR-91 on/off ramp to Project Driveway #2. • Provide stop sign control at the project driveways.
• On-site traffic signing and striping should be implemented in conjunction with detailed construction plans for the project.
• Verify that minimum sight distance is provided at the project driveways.

A queueing analysis was also performed for Project Driveway #2 to ensure adequate vehicular stacking in 2nd Street. Based on the results of the queueing analysis, the TIA recommends the following improvement:
• Construct a 245-foot (minimum) eastbound left-turn lane at Project Driveway #2.

These improvements are a condition of approval for the Project under PP2023-0007 which would reduce impacts to less than significant. Thus, no mitigation was required under the prior MND.

Addendum Finding – Less Than Significant Impact: The Modified Project would be subject to the same roadway improvements identified in the prior MND and will be conditioned accordingly. Furthermore, two additional crosswalk locations were evaluated in the Corona C-Store Trip Generation/Pedestrian Access Evaluation (Trames Solutions, dated September 5, 2024). These included the following:
• Option 1 – Sidewalk to Buena Vista Avenue
• Option 2 – Mid-Block Crossing on 2nd Street
• Option 3 (original option) – 2
nd Street/SR-91
As previously discussed, Option 2 was not recommended by Trames Solutions. Option 3 was originally required for the original project and evaluated in the prior MND. This crosswalk remains as a condition of approval with Option 1 as an alternative location for pedestrians to access the site.

Therefore, the level of impact associated with traffic hazards from design features would remain the same and no mitigation is warranted.
g.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not result in impacts related to emergency access because the project would be permitted and approved in compliance with existing safety regulations, such as the California Building Code and Fire Code (as integrated into the City’s Municipal Code) to ensure that it would not result in inadequate emergency access.

Furthermore, the proposed construction activities, including equipment and supply staging and storage, would occur within the project site and would not restrict access of emergency vehicles to the project site or adjacent areas. During construction, 2 nd
Street would remain open to ensure adequate emergency access to the project area. Thus, impacts related to inadequate emergency access during construction activities would not occur.

As described above, operation of the original project would also not result in inadequate emergency access. Direct access to the project site would be provided from 2nd Street. The driveways and on-site circulation constructed by the project would be

City of Corona 26 Environmental Checklist

evaluated through the City’s permitting procedures to meet the City’s design standards that provides adequate turning space for passenger cars, fire trucks, and delivery trucks. The project is also required to provide fire suppression facilities (e.g., hydrants and sprinklers). The Corona Fire Department (CFD) would review the development plans as part of the plan check and permitting procedures to ensure adequate emergency access pursuant to the requirements in Section 503 of the California Fire Code (Title 24, California Code of Regulations, Part 9). As a result, impacts related to inadequate emergency access would not occur.

Addendum Finding – No Impact: The Modified Project would be subject to the same existing safety regulations such as the California Building Code and Fire Code (as integrated into the City’s Municipal Code) to ensure that it would not result in inadequate emergency access. Construction activities associated with the Modified Project would also be subject to the city’s grading regulations. The Modified Project has been reviewed by the applicable city departments including Building, Fire, and Traffic to ensure that the project has adequate access and on-site circulation. Therefore, the level of impact remains the same as originally determined in the prior MND and no mitigation is warranted. h.

Discussion:
a.

Previous Adopted MND Finding – No Impact: The City of Corona participates in the Multiple Species Habitat Conservation Plan (MSHCP) which is a habitat conservation plan for Western Riverside County that identifies land to be preserved for habitat for threatened, endangered or key sensitive populations of plant and wildlife species. The project site is located within the MSHCP area. However, the project site is not within any MSHCP designated Criteria Areas or Subunits. The project site is also not located within plan-defined areas requiring surveys for criteria area species, narrow endemic species, amphibian species, or mammalian species, including burrowing owl. The Project Applicant is required to pay applicable mitigation fees related to the MSHCP. This fee will be used to acquire and preserve vegetation communities and natural areas, which are known to support these sensitive species. Therefore, the prior MND found that development of the original project is not anticipated to have impacts to endangered species or habit and further mitigation is required.

Addendum Finding – Less Than Significant Impact: The Modified Project would be subject to the same mitigation fees related the MSHCP. Therefore, the level of impact remains the same as previously identified in the prior MND and no mitigation is required.

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 27 Environmental Checklist

b.

Previous Adopted MND Finding – No Impact: Section 6.1.2 of the MSHCP defines Riparian/Riverine areas as “lands which contain Habitat dominated by trees, shrubs, persistent emergent, or emergent mosses and lichens, which occur close to or depend upon soil moisture from a nearby fresh water source; or areas with fresh water flow during all or a portion of the year. The project site is comprised of two remnant parcels that were previously developed for commercial and residential purposes prior to the SR-91 widening project occurring in 2016. Furthermore, the project site is located in a development area surrounded by a freeway, roadways, and commercial and residential developments. The project site vacant and does not contain trees, shrubs, fresh water sources or wetlands. Therefore, the prior MND determined that development of the original project would result in no impacts to riparian habitat or sensitive natural communities, and no mitigation was warranted.

Addendum Finding – Less Than Significant Impact: The “no impact” finding remains the same with development of the Modified Project because the project proposes no expansion to the previously analyzed project site. The proposed use continues to be for commercial purposes, and the layout is generally the same as before. Therefore, no impacts are anticipated, and no mitigation is required.
c.

See discussion under 7b.
d.

Previous Adopted MND Finding – No Impact: The project site has been vacant since 2016 and used as storage area for the SR-91 widening project. The project site is adjacent to a heavily traveled State Route, it will not have any impacts to nor will it interfere with wildlife corridors or migratory species. There are also no trees on the project site. Therefore, the prior MND found that development of the original project would have no impacts wildlife corridors or migratory species.

Addendum Finding – No Impact: The “no impact” finding remains the same with development of the Modified Project as there has been no expansion to the originally analyzed project site that would require additional analysis. There have been no trees or landscaping installed on the site since the adoption of the prior MND that could potentially support wildlife or migratory species.

Previous Adopted MND Finding – Less Than Significant Impact: The previous MND determined that the original project would result in a less than significant impacts related to transporting or accidental release of hazardous materials.

Addendum Finding – Less Than Significant Impact: Implementation of the Modified Project would not change the previous “less than significant finding” determination because the Modified Project would not increase the potential for significant impacts regarding the transport, use and disposal of hazardous materials. The construction operations associated with the proposed Modified Project could involve the handling of incidental amounts of hazardous substances, such as fuel and oil.

Additionally, long-term maintenance activities of the onsite landscaping could involve the use of pesticides. The avoid pubic exposure to hazardous materials, the Modified Project would be subject to local, state and federal laws and regulations regarding the handling and storage of hazardous materials. This would reduce the potential impact of creating a significant hazard to the public or the environment through the routine transport, use or disposal of hazardous materials to less than significant. Compared to the original project, the Modified Project would result in the same level of impact previously determined.
b.

See discussion under 9a.
c.

Previous Adopted MND Finding – Less Than Significant Impact: The nearest school to the Project site is Orange Grove High School located approximately 140 feet southeast of the Project site. The previous MND determined that the original project would not emit hazardous emissions within 0.25 miles of an existing of proposed school.

Addendum Finding – Less Than Significant Impact: Construction of the Modified Project would involve the use, storage and disposal of small amounts of hazardous materials on the Project site. The operations of the commercial development would also involve the use of small hazardous materials related to the maintenance of the buildings, landscaping and other features of the site. The use of these hazardous materials would be limited and used and disposed of in compliance with

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 29 Environmental Checklist

federal, state, and local regulations, which would reduce the potential for accidental release into the environment near a school. The emissions that would be generated from construction and operation of the Project were evaluated in the air quality analysis discussed above, and the emissions generated from the Project would not cause or contribute to an exceedance of the federal or state air quality standards.

The Project’s commercial use includes a gas station which will install gasoline underground storage tanks (USTs) on-site. The USTs would be subject to California’s UST regulations including the UST Program which is overseen by the California State Water Resources Control Board. The UST Program is intended to protect public health and safety, the environment and the State waters from discharges and releases of hazardous substances from the USTs.

Thus, the Modified Project would not emit hazardous or handle acutely hazardous materials, substances, or waste near a school, and impacts would be less than significant.

Previous Adopted MND Finding – No Impact: The closest airport is the Corona Municipal Airport, which is approximately

1.3 miles northwest of the Project site. Based on the Riverside County Airport Land Use Compatibility Plan (ALUCP), the project site is not within any identified safety or compatibility zone. The previous MND determined that the original project would not conflict with the ALUCP.

Addendum Finding – No Impact: The Modified Project would not increase potential airport related hazards to the Corona Municipal Airport. The project would occur in the same general area and would not be within an airport influence area.

Compared to the original project, the Modified Project would result in the same level of impact. f.

Previous Adopted MND Finding – No Impact: The previous MND found that the construction and operation of the original project would not impair the implementation of emergency response plans or evaluation plans.

Addendum Finding – No Impact: The proposed Modified Project would not increase impacts associated with conflicts with adopted emergency plans. The Modified Project would not increase the population in the City because the Modified Project is a commercial development. The construction activities for the Modified Project would not involve any activities that would physically impair or interfere with emergency response plans for the project site. During construction, there could be the potential for temporary lane closures to allow for utility connections and traffic improvements. The temporary lane closures would be for a short period of time and would not interfere with emergency response plans. Additionally, the construction activities for the project would be coordinated with the City, which would identify if traffic controls are needed to maintain emergency response plans. With compliance with City traffic control requirements, potential construction impacts with emergency response plans would be less than significant. Compared to the previously adopted /MND, implementation of the Modified Project would result in the same level of impact in regard to potential conflicts with emergency response plans or evacuation plans for the area.
g.

Previous Adopted MND Finding – No Impact: The previous MND determined that the original project was not in a Fire Hazard Area and would not expose people or structures to significant wildland fire risks.

Addendum Finding – No Impact: The Modified Project would not increase potential to expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fire. As defined in Chapter 3.36 of the Corona Municipal Code, “High Fire Risk Area” applies to any property currently within the City or subsequently annexed into the City, which is also located within or immediately adjacent to the Cleveland National Forest, as well as the urban/wildland interface area approximately 1.5 miles in width running parallel to the boundary of the Cleveland National Forest from the Orange County line to the Indian Truck Trail turnoff on Interstate 15. The project site is not located in close proximity to the Cleveland National Forest nor is it considered an area that can be described as a wildland area. The project site is an infill site located adjacent to the SR-91 freeway and in an urbanized area. Due to the urbanized nature of the surrounding area, the proposed development would not be considered at high risk for fire hazards. Furthermore, all development within the City is required to comply with all fire code requirements associated with adequate fire access, fire flows, and number of hydrants.

Compared to the previously adopted MND, the Modified Project would result in the same level of fire hazard impacts.

Discussion:
a.

Previous Adopted MND Finding – Less Than Significant Impact: A Noise Memorandum for the originalprojectwas prepared by Ganddini Group, dated April 24, 2023 to analyze construction noise impacts associated with the original project. The prior MND determined that the original project would not result in adverse construction noise impacts or long-term operation noise impacts that would exceed local noise standards.

Addendum Finding – No Impact: A Focused Noise Study was prepared for the Modified Project by Ganddini Group, dated August 20, 2024. The following discusses the Modified Project’s potential short-term and long-term noise impacts.

Short-term (Construction) Noise Impact
Construction of the Modified Project would include preparation, grading, paving, building, construction and architectural coating.

Ground-borne noise and other types of construction related noise impacts would typically occur during excavation activities of the grading phase which has the potential to create the highest levels of noise. Construction of the Modified Project is anticipated to last approximately 8 months. Therefore, construction would be short-term and, but can be reduced to a less than significant level by the city’s Municipal Code. Per CMC Chapter 17.84, construction activities are prohibited between the hours of 8:00 p.m. to 7:00 a.m. Monday through Saturday, and 6:00 p.m. to 10:00 a.m. on Sundays and Federal holidays. This will prevent nuisance noise impacts during sensitive time periods for the neighboring commercial and business park properties.

Therefore, no noise mitigation is required of the applicant.

Long-term (Operational) Noise Impacts
Long-term noise impacts associated with the project would be generated from parking lot noise (car engines, doors closing and opening), mechanical HVAC equipment, the carwash drying system associated with the carwash tunnel, and the vacuum systems associated with the 11 vacuum stalls. The project is subject to the City’s noise standards for stationary noise under CMC Section 17.84.040(C). The stationary noise standards are shown in Table 10-A. The criteria is dependent upon the zoning of the receiving land use and the zoning of the source land use. If the receiving and source land uses are located in two different zones, then the standard of the lower standard applies. Furthermore, if the ambient noise level exceeds the resulting standards, the ambient shall be the standard.

The nearest sensitive receptors to the project site are existing multiple family residential uses located approximately 560 feet east (along Buena Vista Avenue), 570 feet south, and 781 feet west (along D Street). There is also a mobile home park located approximately 796 feet southwest (along Lincoln Avenue) of the project site and another mobile home park located approximately 315 feet north (on the other side of the SR-91 freeway) of the project site.

Table 10-A: City of Corona Stationary Noise Standards
Operational noise associated with the Modified Project is not anticipated to be impactful to the surrounding sensitive receptors because the project site is separated from the sensitive receptors by distance and structures (i.e., buildings) which would help to minimize noise emitted from the project site. All mechanical units will be placed either indoors or on the rooftop behind parapet walls which would help to minimize noise. Also, noise associated with the commercial uses would be minimized by the adjacent freeway noise because of the elevated ambient noise levels due to its location adjacent to SR-91.

As shown in Table 10-B, the Modified Project would not violate the City’s stationary noise standards and therefore, would not result in a significant noise impact. No mitigation is required.

Previous Adopted MND Finding – No Impact: The closest airport is the Corona Municipal Airport, which is approximately

1.3 miles northwest of the Project site. Based on the Riverside County Airport Land Use Compatibility Plan (ALUCP), the project site is not within any identified safety or compatibility zone. The previous MND determined that the original project would not conflict with the ALUCP.

Addendum Finding – No Impact: The Modified Project would not increase potential airport related hazards to the Corona Municipal Airport. The project would occur in the same general area and would not be within an airport influence area.

Compared to the original project, the Modified Project would result in the same level of impact.

Previous Adopted MND Finding – No Impact: The Corona Fire Department (CFD), Station 2 will provide all emergency and medical aid calls to the project site. Fire Station 2 is located at 225 E. Harrison Street, approximately 0.92-mile from the project site, and is equipped with a paramedic fire engine company, a paramedic fire truck company, a water tender, and a reserve fire engine. A total of two, eight-person suppression crews staff the fire station 24 hours a day. Average response time to the project site is estimated to be approximately five minutes including travel time and turn-out time. Therefore, the prior MND determined that response times to the project site would not be impacted, and the project would not require the construction of new fire protection facilities.

Addendum Finding – No Impact: The Modified Project would result in the same “no impact” finding as the project site remains the same size as before and the intended use remains commercial. The project’s anticipated impact to fire protection would remain unchanged.
b.

Previous Adopted MND Finding – No Impact: The City of Corona Police Department will provide patrol and emergency response to the project site. The Corona Police Department presently has over 200 employees, including officers and support staff and is stationed at 730 Corporation Yard Way which is approximately 0.5 miles from the project site. The City’s police patrol officers work assigned zones throughout the city; therefore, officers responding to the project site can come from either the city’s police station or from their assigned zone while on patrol. Therefore, the prior MND determined that the original project would not impact police services and would not require the construction of new police protection facilities.

Addendum Finding – No Impact: The Modified Project would result in the same “no impact” finding as the project site remains the same size as before and the intended use remains commercial. The project’s anticipated impact to police

services would remain unchanged.
c.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not impact school services because the project is a commercial development which would not generate student enrollment in the Corona Norco Unified School District. As part of the development impact fees, the project applicant is required to pay school fees based on the square footage of the project at the time of building permits issuance. Therefore, with the required school fee payment to the school district, no additional mitigation was necessary.

Addendum Finding – No Impact: The Modified Project would result in the same “no impact” finding because the project continues to be for commercial use and the project applicant will be required to pay school fees as noted above. Therefore, no mitigation is required.
d.

Previous Adopted MND Finding – No Impact: To offset the project’s potential impact on existing city services, such as streets, parks, library services, police and fire services, the project applicant is required by Corona Municipal Code Chapter

16.23 to pay the adopted development impact fees that are in effect at the time of building permit issuance to offset the added services and infrastructure demands resulting from this project. Therefore, the prior MND determined no additional mitigation is warranted beyond the requirement to pay development impact fees.

Addendum Finding – No Impact: The Modified Project would result in the same “no impact” finding because the project applicant will be required to pay the applicable development impact fees as noted above. Therefore, no mitigation is required. e.

Previous Adopted MND Finding – Less than significant impact: The prior MND determined that the original project would result in a less than significant impact as it pertains to exceeding wastewater treatment requirements.

Addendum Finding – Less than significant impact: The Modified Project would in the same level of impact as previously determined because, all projects are required by the City’s Utilities Department to construct or guarantee the construction of all necessary public water and sewer facilities needed to serve the project. All water and sewer facilities are required to be designed per the standards of the Utilities Department and Riverside County Department of Health Services and will be reviewed by the Utilities Department during the plan check process. Also, Water Reclamation Facility #1 located at 2250 Railroad Street would serve the proposed development and has adequate capacity. The facility currently has a capacity to treat 11.5 mgd (million gallons per day) of sewer. This would reduce the impacts to less than a significant level and therefore, no mitigation would be required.

Previous Adopted MND Finding – Less than significant impact: Per the Hydrology And Hydraulics Study (Woodward Group, May 2024) that was prepared for the original project, the site’s main drainage pattern will be similar to the existing condition. The original project would not result in the construction of new water and wastewater treatment facilities. Therefore, impacts to water and wastewater treatment facilities would be less than significant.

Addendum Finding – Less than significant impact: An updated Hydrology And Hydraulics Study (Woodward Group, August 2024) that was prepared for the Modified Project. The site’s main drainage pattern will be similar to the existing condition. There is no off-site drainage runoff from the area surrounding the site. The proposed on-site sheet flows throughout the site layout and conveys the discharge into an infiltration trench within the site. The infiltration trench was based to contain the 85th percentile 24-hour duration storm event for water quality volume only in accordance with section 4 of the Water Quality Management Plan – Technical Guidance Document for the Santa Ana Region of Riverside County. The Flood events larger than water quality volume, when the infiltration trench has reached capacity, the excess runoff will be discharged into W 2nd Street through a proposed parkway drain. Storm flows generated by the project site travel easterly along 2nd street and Buena Vista Avenue. The infiltration trench will contain and infiltrate the water quality volume for the 85th percentile 24-hour duration storm event and mitigate for a 100 yr. flood pre/post condition. The infiltration trench is located along the northerly property line and will take care of flows from the roof drains, parking lot of the site, and concrete flatwork. For emergency purposes, the parkway drain will serve as the 100-year overflow and discharge into W. Second Ave. existing curb and gutter.

In the pre-development condition, the project site is expected to discharge 22,687 cubic feet of drainage. In post-development condition, the project site is expected to discharge 26,137 cubic feet of drainage. The pre/post difference is 3,450 cubic feet of drainage. The infiltration volume capacity is 3,567 cubic feet, which is sufficient to accommodate the difference of 3,450 cub feet of drainage. Therefore, the Modified Project’s impact to storm drains would be less than significant and no mitigation is required.
d.

Previous Adopted MND Finding – Less than significant impact: A preliminary water quality management plan (WQMP, Woodward Group, revised May 25, 2024) was prepared to evaluate the original project. The prior MND determined that the project would not violate a water quality management plan. Impacts would be less than significant.

Addendum Finding – Less than significant impact: An updated preliminary water quality management plan (WQMP, Woodward Group, revised August 12, 2024) was prepared the project to evaluate the Modified Project. Per the preliminary WQMP, the site currently drains to the southeast corner of the lot and into a city-maintained storm water system. The Modified Project intends to maintain the same drainage pattern. Storm water from the site will be treated by an infiltration trench that is proposed at the southeast corner of the site which will be designed to mimic and exceed the site’s existing infiltration capacity. All flows exceeding the design capture volume will be released from the site and flow into 2nd Street through a parkway drain. As part of the project’s grading permit process, the applicant is required to submit a final WQMP and the city’s Public Works inspector also inspects the project site for compliance with the final approved WQMP during the on-site grading process and at time of project completion. Therefore, the project would not impact water quality or violate water quality standards and no mitigation is required.

The Modified Project would connect to the 12-inch sewer line in West 2nd Street. As required for all projects by the City’s Utilities Department, the project is required to construct or guarantee the construction of all necessary public water and sewer

facilities needed to serve the project. All water and sewer facilities are required to be designed per the standards of the Utilities Department and Riverside County Department of Health Services and will be reviewed by the Utilities Department during the plan check process. Thus, impacts would be less than significant e.

See discussion under 12a.
f.

Previous Adopted MND Finding – Less than significant impact: Waste Management (WM) is contracted by the City of Corona as the sole hauler of solid waste and provider of recycling services. WM provides refuse collection to residential, commercial, and industrial customers. Solid waste from the project would be transported to the El Sobrante landfill located at 10910 Dawson Canyon in Corona. The El Sobrante landfill accepts a maximum 16,054 tons of waste per day and has a remaining capacity of 143,977,170 tons and an estimated closure date of 2051. Per the General Plan Technical Update EIR, the County of Riverside is required to maintain 15 years identified disposal capacity, or have a plan to transform or divert its waste, pursuant to AB 939. Thus, while General Plan buildout could occur after 2051, the County would be required to have 15 years identified disposal capacity after that date. There is adequate landfill capacity in the region for solid waste that would be generated by the 2020-2040 GeneralPlan buildout. Furthermore, new developments approved by the City would berequired to contain storage areas for recyclable materials in conformance with California Public Resources Code Sections 42900 et seq., and the City of Corona Municipal Code Chapter 8.20 (Collection of Refuse and Recyclable Materials). Solid waste diversion program would continue operating and would have adequate capacity to accept all future wastes and recyclables to reduce landfilled waste. Therefore, the prior MND determined that the original project would result in less than significant impacts to landfills and no mitigation is required.

Addendum Finding – Less than significant impact: Implementation of the Modified Project would result in the same level of impact because, and as discussed above, there is adequate capacity in the region for solid waste that would be generated by the 2020-2040 General Plan buildout. Furthermore, the Modified Project would be required to contain storage areas for recyclable materials in conformance with California Public Resources Code Sections 42900 et seq., and the City of Corona Municipal Code Chapter 8.20 (Collection of Refuse and Recyclable Materials). Solid waste diversion program would continue operating and would have adequate capacity to accept all future wastes and recyclables to reduce landfilled waste. Compared to the original project, the Modified Project would result in the same level of impact as it pertains to landfills. g.

Previous Adopted MND Finding – Less than significant impact: The prior MND determined that the project would result in less than significant impact related to potential conflicts with solid waste regulations, because the project would be required to comply with all federal, State, and local regulations related to solid waste. Furthermore, the project would be required comply with all standards related to solid waste diversion, reduction, and recycling during Project construction and operation.

Addendum Finding – Less than significant impact: Implementation of the Modified Project would result in a less than significant impact related to potential conflicts with solid waste regulations because the Modified Project would be required to comply with all federal, State, and local regulations related to solid waste.

Previous Adopted MND Finding – Less than significant impact: According to Figure CD-1 (Scenic Corridors) of the City’s General Plan (2020-2040), the project site is not adjacent to any local or state designated scenic corridor. However, I-15 and SR-91 are designated as “State Eligible Scenic Corridors”. The prior MND determined that the project’s impacts to a scenic vista or highway would be less than significant because the project would be designed per the development standards established by the Corona Municipal Code for the C-3 zone. Also, the project’s architecture would be developed in a manner that is aesthetically compatible with its surrounding area, including details relating to architecture and landscaping. The proposed project would provide paved driveway accesses, screen fencing and landscaping around the perimeters of the property and short screen wall at the drive through lane to buffer vehicle headlights light from nearby drivers.

Addendum Finding – Less than significant impact: The Modified Project would not increase the potential to substantially impact scenic resources or corridors or degrade the visual character of the site and surroundings because the Modified Project is located on the same site that was previously analyzed. The Modified Project would be subject to the C-3 zone development standards. The overall design of the project, including the new freeway sign with the electronic message center, would be reviewed through the city’s precise plan process to ensure compliance with the applicable standards and that the architecture of the commercial buildings are developed in a manner that is aesthetically compatible with its surrounding area, including details relating to architecture and landscaping. Therefore, compared to the original project, the Modified Project would result in the same level of impacts to scenic highways.

Previous Adopted MND Finding – Less than significant impact: The prior MND determined that the project’s impacts to light and glare would be less than significant because the project site is located in a developed area with existing ambient lighting. The area contains existing street light poles along both sides of 2nd Street, lighting from the commercial center parking lot located to the south of the project site, and lighting (light poles and vehicle headlights) along the SR-91 freeway. Additionally, the project is subject to CMC Section 17.84.070, which requires all areas of exterior lighting shall be designed to direct light downward with minimal spillover onto adjacent residences, sensitive land uses, and open space. There are no residential uses located immediately next to the project site.

Addendum Finding – Less than significant impact: The Modified Project would not increase the potential to substantially create more glare than the original project because the Modified Project is located on the same site that was previously analyzed. The site is surrounded by ambient lighting, and the Modified Project would be subject to CMC Section 17.84.070, which requires all areas of exterior lighting shall be designed to direct light downward with minimal spillover onto adjacent residences, sensitive land uses, and open space. There are no residential uses located immediately next to the project site.

Compared to the original project, the Modified Project would result in the same level of light and glare impacts. d.

Previous Adopted MND Finding – Less than significant impact: The prior MND determined that the project site would not result in impacts to scenic resources because the project site is not located adjacent to any forest lands or historic buildings within scenic highways. While SR-91 is a designated “State Eligible Scenic Corridors”, the project’s design and site features including screen walls and perimeter landscaping as discussed under 13.a, will enhance the aesthetic of the site in a manner that will not detract from the SR-91.

Addendum Finding – Less than significant impact: The Modified Project would not increase the potential to substantially impact scenic resources because the Modified Project is proposed on the same site that was previously analyzed. As such, the site is not located adjacent to any forest lands or historic buildings within scenic highways.

Previous Adopted MND Finding – Potentially Significant Unless Mitigation Incorporated: The prior MND evaluated the original project’s potential impacts to the issues analyzed under Section 14, Cultural Resources. A cultural resource analysis was performed for a 4.01-acre parcel (APN 118-270-055) located southeast of the project site, The analysis was prepared

Environmental: Corona Fuel Site 2nd Street Development
City of Corona 39 Environmental Checklist

Dudek, dated April 2024, for a multiple family residential project that was proposed on the 4.01-acre property. The project site is a remnant portion of the 4.01-acre property as as such, the results of the cultural resource analysis for the 4.01-acre property would likely be applicable to the project site which is the reason the cultural resource analysis was included in the prior MND.

A records search for the 4.01-acre property and surrounding area was conducted through the Eastern Information Center (EIC) at the University of California Riverside. The records search indicated that 40 previous studies have been conducted within a 1-mile of the 4.01-acre site. Of the 40 previous studies, three studies intersect the Project site, of which none of the three identified cultural resources within the Project site. While EIC records search did identify 284 cultural resources within 1-mile of the Project site, none of these cultural resources intersected the 4.01-acre property. The records research also included a response from the Native American Heritage Commission on January 19, 2024, stating that results were negative for Native American resources on the subject Project site.

In addition to the record search, the cultural resources analysis also included a field survey which was conducted on January 8, 2024. The field survey noted the 4.01-acre site had remnants of an asphalt surface, likely from the previous mobile home park, grass, gravels and a few trees present with some scattered debris. The field survey also did not identify any cultural resources.

Dudek concluded that although no known significant cultural resources could be impacted by the multiple family residential project, the current status of the property may have affected the potential to discover any surface artifacts. Given that the previous development within the site might have masked archaeological deposits, there is a potential that buried historical resource deposits may be present within the project boundaries. Therefore, Dudek recommended that the multiple family residential project be allowed to proceed with the implementation of a cultural resources monitoring program conducted by an archaeologist and Native American representative(s) during grading of the project site. Dudek recommended Mitigation Measures MM CUL-1 and MM-CUL 2 to reduce impacts to cultural resources to less than significant. The mitigation measures generally require a cultural resource monitoring program during grading activities, impacts to historical resources would be reduced to less-than-significant levels. Since the commercial project site is a remnant portion of the 4.01-acre property, the mitigation measure that were recommended for the multiple family residential project are being recommended for the commercial project. The commercial project’s compliance with MM CUL-1 and MM-CUL 2 would reduce impacts to cultural resources to less than significant. See Section 17, Tribal Cultural Resources for the mitigation measures.

Addendum Finding – Potentially Significant Unless Mitigation Incorporated: The Modified Project would not increase the potential for impacts to Cultural Resources because the Modified Project is proposed on the same project site that was previously analyzed. The Modified Project would be subject to the same mitigation measures that were adopted in the prior MND for the original project. With implementation of Mitigation Measures MM CUL-1 and MM-CUL 2, potential impacts would be less than significant. See Section 17, Tribal Cultural Resources for the mitigation measures.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not conflict with an existing Agricultural zoning or a Wiliamson Act contract because the project site is zoned C-3 (General Commercial) and contains no farmlands.

Addendum Finding – No Impact: Implementation of the Modified Project would not increase the potential to conflict with an existing Agricultural zoning or Williamson Act contact because the Modified Project is proposed on the same site that was previously analyzed. The zoning is C-3 and the site contains no farmlands that are under a Williamson Act contract.

Compared to the original project, the Modified Project would result in the same level of impact as previously determined by the adopted MND for area of concern.

Previous Adopted MND Finding – No Impact: The prior MND determined that the original project would not result in the conversion of prime farmland, unique farmland, or farmland of statewide importance to a non-agricultural use.

Addendum Finding – No Impact: Implementation of the Modified Project would not increase the potential to convert prime farmland, unique farmland, or farmland of statewide importance to a non-agricultural use. According to the California Department of Conservation’s (CDC) California Important Farmland Finder, the Project site is classified as “Urban and Built-Up Land”. The “Urban and Built-Up Land” classification describes land that is occupied by structures with a building density of at least 1 unit to 1.5 acres, or approximately 6 structures to a 10-acre parcel(CDC, 2018). The nearest location of Farmland to the project site is a parcel containing Farmland of local importance that is located approximately 2,500 feet to the north near the intersection of Lincoln Avenue and Railroad Street. Due to the site’s distance from the designated Farmland, the Modified Project does not have the potential to convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland) to non-agricultural use. Compared to the original project, the Modified Project would result in the same level of impact to agricultural resources.

Previous Adopted MND Finding – Less Than Significant Impact: The previous MND estimated that the amount of greenhouse gas emissions the original project would generate is approximately 2,758.27 MTCO2e per year. Since this is less than SCAQMD’s numeric threshold of 3,000 MtCO2e per year, the project’s impacts would be less than significant.

Addendum Finding – Less Than Significant Impact: Per the Modified Project’s Air Quality, Global Climate Change, and Energy (Ganddini, July 26, 2024), the Modified Project’s estimated GHG emissions is approximately 2,442.30 MTCO2e per year. Since this is less than SCAQMD’s numeric threshold of 3,000 MtCO2e per year, the Modified Project’s impacts would be less than significant. Compared to the original project, the Modified Project would result in the same level of impact as it pertains to greenhouse gas emissions.
b.

Previous Adopted MND Finding – No Impact: The previous MND determined that the original project would not conflict with an applicable plan, policy or regulation to reduce greenhouse gas emissions.

Addendum Finding – No Impact: Implementation of the Modified Project would not conflict with an applicable plan, policy or regulation to reduce greenhouse gas emissions. The Modified Project would not increase greenhouse gas emissions above the SCAQMD’s numeric threshold of 3,000 MtCO2e per year, and therefore, would be in compliance with the Corona Climate Action Plan. Compared to the original project, the Modified Project would result in the same level of impact regarding potential conflicts with an applicable plan, policy or regulation to reduce greenhouse gas emissions.
