1.0 INTRODUCTION

1.1 OVERVIEW
The 2010 Renaissance Specific Plan (2010 RSP) was approved by the City of Rialto (City) on November 23, 2010. The 2010 RSP comprised approximately 1,445.3 acres (gross) and allowed for development of up to 16.2 million square feet (sf) of business and commercial uses, 1,667 residential units, a school, a community park, and multiple neighborhood parks. Potential environmental impacts of the 2010 RSP were evaluated in the Renaissance Specific Plan Final Environmental Impact Report (2010 Final EIR) (State Clearinghouse [SCH] No. 2006071021).

The 2016 Renaissance Specific Plan Amendment (2016 RSPA) area comprised approximately 1,450.7 acres (gross) located in the northwesterly portion of the City of Rialto (City). The 2016 RSPA was planned as an integrated community of varied housing types located near, and linked to, places of employment, retail uses, services, and schools.

The 2016 RSPA included 149.5 acres of residential uses; 935.1 acres of nonresidential uses including retail, commercial office and industrial uses; a school; a community park; and multiple neighborhood parks proximate to one another and organized in a grid pattern.

Required infrastructure improvements were identified in the 2016 RSPA and their potential environmental impacts were evaluated as a part of the 2016 RSPA project in the Certified Final Recirculated Subsequent Environmental Impact Report (2016 Final SEIR, Certified EIR) (State Clearinghouse [SCH] No. 2006071021). The Final SEIR comprises the following:

• Recirculated Draft SEIR;
• Recirculated Draft SEIR Appendices;
• Responses to Comments on the Draft Recirculated Draft SEIR; and • Recirculated Draft SEIR Errata.

Any yard trucks based at the Project site would be non-diesel (e.g., natural gas, gasoline and/or electric-powered).

1.4 CALIFORNIA ENVIRONMENTAL QUALITY ACT DOCUMENTATION
California Environmental Quality Act (CEQA) documentation for the 2016 RSPA is presented in the Certified Final Recirculated Subsequent Environmental Impact Report (2016 Final SEIR, Certified EIR) (State C learinghouse [SCH] No. 2006071021). This Addendum to the Certified EIR (Addendum) compares the impacts that were identified in the Certified EIR with the anticipated impacts of the 2016 RSPA as modified by the Project described herein. This Addendum substantiates that the 2022 Amendment Project would not result in new significant impacts, substantially different impacts, or impacts that would be substantially more severe than those evaluated and addressed in the Certified EIR.

1.5 ADDENDUM PURPOSE AND SUMMARY
The focus and purpose of this document is to determine if the Amendment Project described herein would result in new or substantially different environmental impacts © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Introduction
2022 Addendum to the 2016 Final EIR Page 1-5
than those considered and addressed in the Certified EIR. To these ends, this Addendum defines, describes, compares, and contrasts potential environmental impacts of the 2022 Amendment Project in the context of the environmental impacts assessed in the Certified EIR. In so doing, this Addendum substantiates consistency with applicable California Environmental Quality Act Guidelines (CEQA Guidelines ) provisions addressing preparation of an Addendum to a previously-Certified EIR.

In these regards, as presented at CEQA Guidelines Section 15164, an Addendum to a Certified EIR may be prepared if only minor technical changes or additions are necessary and none of the conditions described in Section 15162, calling for the preparation of a subsequent or supplemental EIR, have occurred. Further, Public Resources Code Section 21166 prohibits preparation of a subsequent or supplemental EIR for a C ertified EIR unless substantial project changes are proposed requiring major revisions to the Certified EIR; a substantial change in circumstances has occurred requiring major revisions to the Certified EIR; or new information becomes available requiring major revisions to the Certified EIR. As supported by the information provided here, none of these conditions apply to the 2022 Amendment Project. This Addendum to the Certified EIR fulfills CEQA documentation requirements.

1.6 INTENDED USE OF THIS ADDENDUM

The City of Rialto (City) is the Lead Agency for the purposes of CEQA because it has the principal responsibility and authority for consideration of discretionary actions and permitting for the Amendment Project. As the Lead Agency, the City is also responsible for analyzing the Project’s potential environmental impacts.

The Lead Agency will employ this Addendum in its evaluation of potential environmental impacts resulting from, or associated with, approval and implementation of the 2022 Amendment Project. This Addendum may also be used by various Responsible Agencies, e.g., Air Quality Management District(s), Regional Water Quality Control Board(s), et al.; as well as utilities and service providers when such entities issue discretionary permits necessary to carry out the Amendment Project.

Renaissance Specific Plan, 2022 Amendment Introduction
2022 Addendum to the 2016 Final EIR Page 1-6
For example, if the Amendment Project would require discretionary permits from the South Coast Air Quality Management District (SCAQMD), this Addendum would serve as the environmental assessment for such permits (please refer to California Code of Regulations, Section 15050).

Individual aspects of the Amendment Project described herein , including building configuration and building size, may be modified in the future as the Project is further defined. However, provided the overall maximum scope of the Project and/or Project uses are not substantially altered, the analysis presented here is not affected. Analyses within this Addendum reflect the scope and types of uses proposed by the Amendment Project described herein. Should future development proposals differ substantially from the development concepts analyzed herein, the Lead Agency would comply with CEQA in consideration of those proposals.

ENVIRONMENTAL CHECKLIST
Renaissance Specific Plan, 2022 Amendment
2022 Addendum to the 2016 Final EIR

General Notes: The CEQA Initial Study Checklist categories and topics presented below conform to the suggested content presented in the 2021 CEQA Guidelines, Appendix G. In certain instances, the 2021 CEQA Guidelines Initial Study Checklist content differs from that presented in the 2016 Renaissance Specific Plan Amendment, Certified Final Recirculated Subsequent Environmental Impact Report (2016 Final SEIR, Certified EIR) (State Clearinghouse [SCH] No. 2006071021). The Final SEIR comprises the following:

• Recirculated Draft SEIR;
• Recirculated Draft SEIR Appendices;
• Responses to Comments on the Draft Recirculated Draft SEIR; and • Recirculated Draft SEIR Errata.

Additional or new environmental topics considered in the 2021 CEQA Initial Study Checklist, and not reflected in the Certified EIR, are recognized in the discussions below. Other Certified EIR discussions have been restructured or paraphrased to align with the format and content of the 2021 CEQA Initial Study Checklist, with no substantial effect on environmental findings or conclusions. This Addend um compares and contrasts impacts of the 2022 Amendment Project with impacts identified in the Certified EIR.

Substantiation:

a-d) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR recognizes that transition of the vacant site to uses proposed under the 2016 RSPA would alter the visual character of the area .

However, the Certified EIR determined that development of the site as proposed under the RSPA would enhance the visual attributes of the area. Mitigation is included in the Certified EIR to ensure that potentially adverse visual impacts of above ground electrical service a nd communications lines are avoided. With incorporation of mitigation, the Certified EIR concluded that the potential for the 2016 RSPA to result in adverse impacts as delineated at Checklist Items 1. a – d would be less-than-significant (Certified EIR, pp.

4.1-5 – 4.1-16).

Certified EIR Mitigation Measure:

AES-1 Pursuant to Section 15.32 of the City’s Municipal Code Prior to the issuance of grading permits or improvement plans, the project applicant shall submit to the satisfaction of the Public Works Director, evidence that all electrical distribution lines of 16,000 volts or less, telephone lines, cable antenna television and similar service wires or cable, which provide direct service to the property being developed, shall be installed underground.

2022 Amendment Project: Final designs of the Project facilities including, but not limited to, the proposed buildings, landscape/hardscape features , and lighting configurations would be required to conform to applicable RSPA D esign Guidelines and Development Standards as amended ,
1 and applicable provisions of the City Municipal Code. Final designs of all uses would be subject to City review and approval. Conformance with the RSPA Specific Plan Design Guidelines and Development Standards and City Municipal Code requirements would ensure that the Project would not substantially degrade scenic vistas, substantially degrade scenic resources, adversely alter the existing visual character or quality of the area , or create a new source of substantial light or glare which would adversely affect day or nighttime views . Additionally, the Project would implement Certified EIR Mitigation Measure AES-1, thereby ensuring that potentially adverse visual impacts associated with overhead electrical and communications lines would be avoided.

On this basis, when compared to the Certified EIR findings, n o new or substantially increased aesthetic impacts would result from the Project.

2022 Amendment Project Mitigation Measures: Certified EIR Mitigation Measure AES- 1 is applicable to the Amendment Project and is carried forward in this Addendum.

X
b) Conflict with existing zoning for
agricultural use, or a Williamson Act
contract?

X
c) Conflict with existing zoning for, or
cause rezoning of, forest land (as
defined in Public Resources Code
section 1220(g)), timberland (as

X
d) Result in the loss of forest land or
conversion of forest land to non- forest
use?

X
e) Involve other changes in the existing
environment which, due to their
location or nature, could result in
conversion of Farmland to non-
agricultural use, or conversion of forest
land to non-forest use?

Substantiation:

a-e) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR concluded that implementation of the 2016 RSPA would not adversely affect any existing agricultural resources or operations. The property does not contain an y forest land or support forestry services. No Prime Farmland, Unique Farmland, or Farmland of Statewide or Local Importance is mapped in the Project vicinity, so the 2016 RSPA would not adversely affect other agricultural © 2022 Applied Planning, Inc.

properties or result in the conve rsion of farmland to non -agricultural use or forest land to a non-forestry use (Certified EIR, pp. 6-4 – 6-5).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The Project proposes conventional light industrial/warehouse uses within and urbanized area of the City. No agricultural resources exist within or proximate to the Project site. No Prime Farmland, Unique Farmland, or Farmland of Statewide or Local Importance is mapped within the Project site or in the Project vicinity.

See also: https://maps.conservation.ca.gov/dlrp/ciff/. The Project site is not the subject of or affected by a Williamson Act Contract. The Project does not propose or re quire facilities or operations that would potentially adversely affect any off -site Farmlands, Williamson Act Contract properties, or other agricultural uses.

The Project site is not zoned for forest land, timberland, or timberland zoned Timberland Production. No forest land is located within or proximate to the Project site. T he Project does not require or propose “other changes” to the environment which could result in the conversion of farmland or forestland to other uses.

When compared to the 2016 RSPA , no new significant, substantially increased, or substantially different impacts would occur as a result of the 2022 Amendment Project.

No changed or new information has been identified to indicate that any potential agriculture or forestry resources impacts resulting from the 2022 Amendment Project would be different from those previously identified and addressed in the Certified EIR.

2022 Amendment Project Mitigation Measures: None.

Substantiation: Air quality impacts of the 2022 Amendment Project, as discussed below, are summarized in part from:

• Orbis Rialto II , Air Quality Impact Analysis, City of Rialto (Urban Crossroads, Inc.) January 20, 2022.

• Orbis Rialto II , Mobile Source Health Risk Assessment , City of Rialto (Urban Crossroads, Inc.) January 20, 2022.

Both documents are presented in their entirety at Addendum Appendix A.

a) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR determined that the 2016 RSPA would not result in any new or substantially increased AQMP consistency impacts when compared to the approved 2010 RSP (Certified EIR, pp. 4.2-17 – 4.2-26).

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-7
Certified EIR Mitigation Measures: None.

2022 Amendment Project : Criteria for determining consistency with the AQMP are defined in Chapter 12, Section 12.2 and Section 12.3 of the 1993 CEQA Handbook , as follows:

• Consistency Criterion No. 1
The project will not result in an increase in the frequency or severity of existing air quality violations or cause or contribute to new violations or delay the timely attainment of air quality standards or the interim emissions reductions specified in the AQMP.

• Consistency Criterion No. 2
The project will not exceed the assumptions in the AQMP based on the years of project buildout phase. The 2016 AQMP demonstrates that the applicable ambient air quality standards can be achieved within the timeframes required under federal law. Growth projections from local general plans adopted by cities in the district are provided to the SCAG, which develops regional growth forecasts, which are then used to develop future air qualit y forecasts for the AQMP.

Development consistent with the growth projections in City of Rialto General Plan is considered to be consistent with the AQMP.

The following discussions evaluate the 2022 Amendment Project’s consistency with the above Criterion.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-8
Consistency Criterion No. 1

The violations that Consistency Criterion No. 1 refers to are the California Ambient Air Quality Standards (CAAQS) and National Ambient Air Quality Standards National Ambient Air Quality Standards (NAAQS). CAAQS and NAAQS violations would occur if regional or localized significance thresholds were exceeded.

As presented within the Air Quality Impact Analysis , and summarized under Checklist item b, the 2022 Amendment Project’s regional and localized construction and operational-source emissions would not exceed applicable regional or localized significance thresholds.

Consistency Criterion 2

Construction Impacts
Peak day emissions generated by construction activities are largely independent of land use assignments, but rather are a function of development scope and maximum area of disturbance. Irrespective of the site’s land use designation, development of the site to its maximum potential would likely occur, with disturbance of the entire site occurring during construction activities. However, as mentioned above, no applicable regional or localized significance thresholds would be exceeded by construction of the 2022 Amendment Project.

Operational Impacts
The site is currently designated for “Corporate Center” land uses. To accommodate the 2022 Amendment Project ’s proposed warehouse use, the land use designation of the Project site would be changed from Corporate Center to “Business Center.” The Project does not propose or require amendment of the site’ s existing underlying General Plan Land Use designation of “Specific Plan.”

The proposed warehouse use is permitted under the proposed “Business Center” land use designation. Furthermore, operations of the 2022 Amendment Project would not result in or cause exceedances of regional or localized air quality significance thresholds. © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-9
Emissions generated by the 2022 Amendment Project are accurately represented in the AQMP emissions modeling, air pollution control strategies, and associated assumptions for emissions affecting the Basin.

Conclusion
The Project would not have the potentia l to result in or cause NAAQS or CAAQS violations. Additionally, Project construction and operational -source emissions would not exceed regional or localized significance thresholds. Further, the Project would not exceed the assumptions in the AQMP based on the years of Project build-out phase. The Project is therefore considered to be consistent with the AQMP. Based on the preceding, when compared to the Certified EIR findings, no new or substantially increased AQMP consistency impacts would occur under the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

b) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR concluded that although certain SCAQMD emission thresholds for criteria pollutants would be exceeded by the 2016 RSPA, the emissions predicted for the overall RSP Project would exceed the daily emissions thresholds of these criteria pollutants, so no new exceedances would occur. The following mitigation measures from the 2010 RSP project were carried forward into the Certified EIR (Certified EIR, pp. 4.2-26 – 4.2-34).

Certified EIR Mitigation Measures:

AQ-1 Standard Air Quality Conditions

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-10
controlled with best-available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. In addition, SCAQMD Rule 403 requires implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off site. Applicable dust suppression techniques from Rule 403 are summarized below. Implementation of these dust suppression techniques can reduce the fugitive dust generation (and thus the PM10 component). Compliance with these rules would reduce impacts on nearby sensitive receptors (see SCAQMD Rule 403).

This applicable Rule measures as follows:
• Apply nontoxic chemical soil stabilizers according to manufacturers’ specifications to all inactive construction areas (previously graded areas inactive for 10 days or more). • Water act ive sites at least twice daily. (Locations where grading is to occur will be thoroughly watered prior to earthmoving.)
• Cover all trucks hauling dirt, sand, soil, or other loose materials, or maintain at least 0.6 meters (2 ft) of freeboard (vertical space between the top of the load and top of the trailer) in accordance with the requirements of California Vehicle Code (CVC) Section 23114. • Pave construction access roads at least 100 ft (30 m) onto the site from the main road. • Reduce traffic speeds on all unpaved roads to 15 mph or less.

The applicable California Department of Resources Recycling and Recovery (CalRecycle) Sustainable (Green) Building Program Measures are:
• Recycle/reuse at least 50 percent of the construction material including, but not limited to, soil, mulch, vegetation, concrete, lumber, metal, and cardboard. • Use “green building materials” such as those materials that are rapidly renewable or resource-efficient, and recycled and manufactured in an environmentally friendly way, for at least 10 percent of the project.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-11
Operations
Prior to the issuance of building permits, the project applicant shall submit to the satisfaction of the Public Works Director, evidence that development within the Renaissance Marketplace and Planning Area 108 comply with Title 24 of the California Code of Regulations (CCR) established by the CEC regarding energy conservation and green buildings standards. The project applicant shall incorporate the following in building plans:
• Low-emission water heaters shall be used. Solar water heaters are encouraged. • Exterior windows shall utilize window treatments for efficient energy conservation.

These measures will result in reduced emissions during the construction and operation phases of the proposed Renaissance Marketplace and Planning Area 108 projects.

AQ-2 Sensitive Receptors – 500-Foot Buffer
Prior to the issuance of any grading permits, the project applicant shall submit, to the satisfaction of the Public Works Director and Planning Division, evidence that the following uses will not be located within the distance specified from an existing or future sensitive receptor (residence, school, hospital, nursing home, day care centers, parks and playgrounds): within 500 feet of the 210 Freeway; within 500 feet of the equipment within a dry cleaning facility utilizing Perchloroethylene; and within 300 feet of a fueling station facility (i.e. fuel pumps). These facilities may be located closer than the proscribed distances if a project -specific health risk assessment is performed that demonstrates that the project -specific health risk impacts do not exceed the South Coast Air Quality Management District’s health risk significance thresholds.

AQ-3 Sensitive Receptors – 1,000-Foot Buffer
Prior to the issuance of any grading permits, the project applicant shall submit, to the satisfaction of the Public Works Director and Planning Division, evidence that the following uses will not be located within 1000 feet of a nearby sensitive receptor (occupied portions of existing or future residences, schools, hospitals, nursing homes, day care centers, parks, and playgrounds): a warehouse, distribution center, or logistics center unless a project -specific health risk assessment is performed that demonstrates that the project-specific health risk impacts do not exceed the South Coast Air Quality Management District’s health risk significance thresholds.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-12
AQ-4 Off-Road Diesel Equipment
Prior to the issuance of any grading permits, the project applicant shall submit, to the satisfaction of the Public Works Director and Planning Division, evidence that off-road diesel -powered construction equipment greater than 50 horsepower will meet the Tier 4 emission standards, where feasible. In addition, wh ere feasible all construction equipment shall be outfitted with Best Available Control Technology (BACT) devices certified by the Air Resources Board (ARB). Any emissions control device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by a Level 3 diesel emissions control strategy for a similarly sized engine as defined by ARB regulations.

AQ-5 Construction Equipment Tier Specification
Prior to the mobilization of each applicable offroad diesel-powered construction equipment greater than 50 horsepower, the project applicant shall submit, to the satisfaction of the Public Works Director and Planning Division, a copy of the certified tier specification, Best Available Control Technology (BACT) documentation, and Air Resources Board or South Coast Air Quality Management District’s operating permit for each shall be provided at the time of mobilization of each applicable unit of equipment.

AQ-6 Truck Access
Prior to the issuance of any grading permits, the project applicant shall submit, to the satisfaction of the Public Works Director and Planning Division, evidence that the following truck access routes have been incorporated into the project design, to the maximum extent practicable, to reduce air quality and potential future health risk impacts from the operation phases of the proposed project:

• Design warehouse/distribution centers such that entrances and exits discourage trucks from traversing past neighbors or other sensitive receptors. • Design warehouse/distribution centers such that any check-in point for trucks is well inside the facility property to ensure that there are no trucks queuing outside of the facility.

As presented at Table 3-1, 2022 Amendment Project construction-source emissions would not exceed applicable SCAQMD regional thresholds and would therefore be less -than- significant. Per SCAQMD criteria, less- than-significant impacts at the project level are not cumulatively considerable. On this basis, the 2022 Amendment Project construction- source emissions would not contribute considerably to cumulative non -attainment criteria pollutant impacts.

As indicated at Table 3-2, 2022 Amendment Project operational-source emissions would not exceed applicable SCAQMD regional thresholds and would therefore be less -than- significant. Per SCAQMD criteria, less- than-significant impacts at the project level are not cumulatively considerable. On this basis, the 2022 Amendment Project construction- source emissions would not contribute considerably to cumulative non -attainment criteria pollutant impacts.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-15
Localized Significance Thresholds
The SCAQMD has established that impacts to air quality are significant if there is a potential to contribute or cause localized exceedances of the federal and/or state ambient air quality standards (NAAQS/CAAQS). Collectively, these are referred to as Localized Significance Thresholds (LSTs). LSTs represent the maximum emissions from a project that would not cause or contribute to an exceedance of the most stringent applicable NAAQS and CAAQS at the nearest residence or sensitive receptor.

As part of the Project -specific Air Quality Analysis, localized air quality impacts were evaluated at receptor land uses nearest the Project site. Based on SCAQMD’s LST Methodology, emissions for concern during construction and operational activities are NO
X, CO, PM2.5, and PM10. Tables 3-3 and 3-4 present the localized impacts at the nearest receptor location in the vicinity of the Project site during construction and operations.

CO “Hotspot” Analysis
It has long been recognized that CO hotspots are caused by vehicular emissions, primarily when idling at congested intersections. In response, vehicle emissions standards have become increasingly stringent in the last twenty years. Currently, the allowable CO emissions standard in California is a maximum of 3.4 grams/mile for passenger cars (there are requirements for certain vehicles that are more stringent). With the turnover of older vehicles, introduction of cleaner fuels, and implementation of increasingly sophisticated and efficient emissions control technologies, CO concentration in the SCAB is now designated as attainment.
© 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-17
To establish a more accurate record of baseline CO concentrations affecting the SCAB, a CO “hot spot” analysis was conducted in 2003 for four busy intersections in Los Angeles at the peak morning and afternoon time periods. This “hot spot” analysis did not predict any violation of CO standards.

Based on the SCAQMD's 2003 AQMP and the 1992 Federal Attainment Plan for Carbon Monoxide (1992 CO Plan), peak carbon monoxid e concentrations in the SCAB were a result of unusual meteorological and topographical conditions , not a result of traffic volumes and congestion at a particular intersection. As evidence of this, at the highest CO generating intersection within the “hot s pot” analysis ( Long Beach B oulevard and Imperial Highway intersection), of the 8.4 ppm 8-hr CO concentration measured, only 0.7 ppm was attributable to the traffic volumes and congestion at this intersection; the remaining 7.7 ppm were due to the ambient air measurements at the time the 2003 AQMP was prepared. In contrast, an adverse CO concentration, known as a “hot spot”, would occur if an exceedance of the state one-hour standard of 20 parts per million (ppm) or the eight-hour standard of 9 ppm were to occur.

The busiest intersection evaluated within the 2003 “hot spot” analysis was that at Wilshire Boulevard and Veteran Ave nue, which has a daily traffic volume of approximately 100,000 vph and AM/PM traffic volumes of 8,062 vph and 7,719 vp , respectively. The 2003 AQMP estimated that the 1-hour concentration for this intersection was 4.6 ppm; this indicates that, should the daily traffic volume increase four times to 400,000 vehicles per day, CO concentrations (4.6 ppm x 4= 18.4 ppm) would still not likely exceed the most stringent 1-hour CO standard (20.0 ppm).

For the 2022 Amendment Project, the intersection of Alder Ave nue and Renaissance Parkway would have the highest AM/PM traffic volumes of 3,622 vph and 3,840 vph, respectively. Total traffic volum es at the intersections considered are substantially less than the traffic volumes identified in the 2003 AQMP “hot spot” analysis. Moreover, the ambient 1-hr and 8-hr CO concentration within the Project study area is estimated to be

1.7 ppm and 1.2 ppm, respectively (data from Central San Bernardino Valley station for 2020). These values are substantially less than the ambient CO conditions reflected in the 2003 analysis. Therefore, even if the traffic volumes for the 2022 Amendment Project were © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-18
double or even triple of the traffic volumes generated at the Long Beach B oulevard and Imperial Highway intersection, coupled with the on-going improvements in ambient air quality, the Project would not be capable of resulting in a CO “hot spot” at any study area intersections.

Similar considerations are also employed by other Air Districts when evaluating potential CO concentration impacts. More specifically, the Bay Area Air Quality Management District (BAAQMD) concludes that under existing and future vehicle emission rates, a given project would have to increase traffic volumes at a single intersection by more than 44,000 vehicles per hour (vph)—or 24,000 vph where vertical and/or horizontal air does not mix—in order to generate a significant CO impact.

As summarized above, the 2022 Amendment Project , along with background and cumulative development, would not produce the volume of traffic required to generate a CO “hot spot” either in the context of the 2003 Los Angeles hot spot study or based on representative BAAQMD CO threshold considerations. Localized air quality impacts related to mobile-source emissions would therefore be less-than-significant.

Summary
Based on the preceding, when compared to the Certified EIR findings, the 2022 Amendment Project would not result in substantively different or substantively increased contributions to cumulative contributions to criteria pollutant non -attainment impacts.

2022 Amendment Project Mitigation Measures: Although no Project-specific mitigation is necessary for the Amendment P roject, Certified EIR Mitigation Measures A Q-1 through AQ-6 are carried forward in this Addendum.

c) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR included a localized impact analysis, a CO hot spot analysis , and a Health Risk Assessment (HRA) to assess impacts to nearby sensitive receptors. The Certified EIR concluded that applicable thresholds would not be © 2022 Applied Planning, Inc.

exceeded, and no significant impacts to nearby sensitive receptors were identified (Certified EIR, pp. 4.2-30 – 42-31).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The Project HRA evaluated the potential health risk impacts to sensitive receptors and adjacent workers associated with the development of the proposed site. More specifically, health risk impacts as a result of exposure to Toxic Air Contaminants (TACs) incl uding diesel particulate matter (DPM) were evaluated . The HRA identified six receptors, R1 through R6, as illustrated at Exhibit 2 -D of the HRA (Addendum Appendix A).

Construction Impacts
The land use with the greatest potential exposure to Project construction DPM source emissions is identified as Location R1 . This receptor is an existing residence, located approximately 1,995 feet northeast of the Project site.

As presented within the HRA , the maximum incremental cancer risk attributable to Project co nstruction DPM source emissions at Location R1 is estimated at 0.07 in one million, which is less than the SCAQMD’s significance threshold of 10 in one million. At this same location, non-cancer risks were estimated to be <0.01, which would not exceed the applicable threshold of 1.0. As such, the 2022 Amendment Project will not cause a significant human health or cancer risk to adjacent land uses as a result of Project construction activity. All other receptors during construction activity would experience less risk than what is identified for this location.

Operational Impacts

Residential Exposure Scenario
As previously mentioned, the residential land use with the greatest potential exposure to Project DPM source emissions is Location R1. At this location, the maximum incremental cancer risk attributable to Project DPM source emissions is estimated at 0.03 in one million, which is less than the SCAQMD’s significance threshold of 10 in one million. At © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-20
this same location, non-cancer risks were estimated to be <0.01, which would not exceed the applicable significance threshold of 1.0. Because all other modeled residential receptors are exposed to lesser concentrations and are located at a greater distance from the Project site and primary truck route (TACs generally dissipate with distance from the source), all other residential receptors in the vicinity of the Project site would be exposed to less emissions and therefore less risk than Location R1 . As such, the Project will not cause a significant human health or cancer risk to nearby residences.

Worker Exposure Scenario
The worker receptor land use with the greatest potential exposure to Project DPM source emissions is Location R6, which represents the adjacent poten tial worker receptor approximately 191 feet south of the Project site. At th is location , the maximum incremental cancer risk impact is 0.04 in one million which is less than the SCAQMD’s threshold of 10 in one million. Maximum non-cancer risks at this same location were estimated to be <0.01, which would not exceed the applicable significance threshold of

1.0. Because all other modeled worker receptors are located at a greater distance than Location R6 (DPM dissipates with distance from the source), all other worker receptors in the vicinity of the Project would be exposed to less emissions and therefore less risk than Location R6. As such, the Project will not cause a significant human health or cancer risk to adjacent workers.

School Child Exposure Scenario
A one-quarter mile radius, or 1,320 feet, is commonly utilized for identifying sensitive receptors, such as schools, that may be impacted by a proposed project. There are no schools located within one-quarter mile of the Project site. The nearest school is Wilmer Amina Carter High School, which is located approximately 3,850 feet northeast of the Project site. Because there is no reasonable potential that TAC emissions would cause significant health impacts at distances of more than one-quarter mile from the air pollution source, there would be no significant impacts that would occur to any schools in the vicinity of the Project.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-21
Summary
The 2022 Amendment Project will not cause a significant human health or cancer risk to adjacent land uses as a result of construction and operational activity. Please refer also to HRA Tables ES-1 through ES-3, and HRA Exhibit 2-D.

Based on the preceding, the 2022 Amendment Project would not expose sensitive receptors to harmful pollutant concentra tions. When compared to the Certified EIR findings, no new or substantially increased pollutant concentrations impacts to sensitive receptors would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

d) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study prepared for the 2016 RSPA determined that the proposed Project would not be a source of objectionable odors, and no impact would occur. No fur ther analysis was included in the Certified EIR. (Initial Study, Certified EIR Appendix A, p. 27).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: Temporary, short- term odor releases are potentially associated with Project construction activities. Potential sources of odors include, but are not limited to: asphalt/paving materials, glues, paint, and other architectural coatings.

Construction-source o dor impacts are mitigated by established requirements for a material handling and procedure plan, which identifies odor sources, odor -generating materials and quantities permitted on site, and isolation/containment devices or mechanisms to prevent significant release of odors.

The Project light industrial uses do not comprise facilities that would be sources of objectionable odor emissions. Project-generated refuse is required to be stored in covered containers and removed at regular intervals in complian ce with City solid waste management regulations – thereby precluding any significant odor impacts. Further, the © 2022 Applied Planning, Inc.

Substantiation: Biological resources impacts of the 2022 Amendment Project, as discussed below, are summarized in part from Renaissance Biological Surveys (Harmsworth Associates) February 8, 2022. This memo is presented in its entirety at Addendum Appendix B.

a) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR recognize d certain potential impacts to sensitive species, as follows.

Coastal California Gnatcatcher
Although no sightings of the Coastal California Gnatcatcher have occurred onsite during any previous surveys, the species has been sighted nearby. The site is not located within federally designated Critical Habitat for California gnatcatcher. However, the area does contain buckwheat scrub, which is a habitat that is used by the California Gnatcatcher.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-24
Certified EIR determined that with the implementation of Mitigation BIO -1, impacts would be reduced to less-than-significant.

San Bernardino Kangaroo Rat
The northwestern portion of the Specific Plan area contains marginal habitat for the federally endangered and State threatened San Bernardino Kangaroo Rat (Dipodomys merriamii). Field sign, including burrows, dusting baths, and tail drags, for kangaroo rat was observed during previous surveys. The observed k angaroo rat sign is presumed to be Dulzura kangaroo rat, a non -listed kangaroo rat species, and San Bernardino Kangaroo Rat was determined to have a low potential for occurrence.

The Certified EIR determined that although the Specific Plan area does not provide suitable habitat to sustain a San Bernardino Kangaroo Rat population over the long-term, a residual population could still occur onsite. As such, the Certified EIR determined that Mitigation Measure BIO-2 would reduce impacts to a less-than-significant level.

Burrowing Owl
The Specific Plan area provides suitable nesting, foraging, and dispersing habitat for the western burrowing owl ( Athene cunicularia). The development of the Specific Plan area would effectively remove all suitable habitat permanently. Burrowing owl have been observed on t he site during previous surveys and suitable habitat is present . Certified EIR Mitigation Measure BIO- 3 requires a burrowing owl focused presence/absence survey, and outlines protocol should b urrowing owl continue to occupy the area. The Certified EIR det ermined that, with the incorporation of Mitigation Measure BIO- 3, impacts would be less-than-significant.

Sensitive Plant Species
The Certified EIR concluded that some habitat potential exists for Plummer’s mariposa - lily and Parry’s spineflower within the area. Potential impacts to these sensitive plant species was deemed significant and mitigation was proposed . With implementation of Mitigation Measure BIO-4, potential impacts would be reduced to a less-than-significant level.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-25
Sensitive Plant Habitat
The Specific Plan area is not located within federally designated Critical Habitat. One sensitive plant community was observed within the Project area during the habitat assessment: Riversidian Alluvial Fan Sage Scrub ( RAFSS). However, this plant community is heavily disturbed and has been effectively cut -off from fluvial processes.

The disturbed mature RAFSS habitat and rocky soils that occupy the area do not provide suitable habitat for sensitive biological resources. Nonetheless, the habitat is still considered to have some biological value, and development within the area would result in the removal of RAFSS habitat. Potential impacts to RAFSS were considered significant and mitigation wa s proposed. With implementation of Mitigation Measure BIO- 5, the Certified EIR concluded that potential impacts would be reduced to less-than-significant (Certified EIR, pp. 4.3-12 – 4.3-18).

Certified EIR Mitigation Measures:

BIO-1 California Gnatcatcher
Prior to the issuance of grading permits, the project applicant shall submit to the satisfaction of the Development Services Director/Planning Division, evidence that focused surveys have been undertaken to determine the presence/absence of this species as indicated below. Surveys shall follow protocols established by the U.S. Fish and Wildlife Service (USFWS).

Portions of the Project area have been determined to contain suitable habitat for California Gnatcatcher (CAGN) (Planning Areas 58, 104, 108, 110, 113, 114, 115, and 119, as appropriate).

Prior to development of those planning areas, focused surveys must be undertaken to determine the presence/absence of this species. Surveys shall follow protocols established by the USFWS. In the event that CAGN is detected or observed within the disturbance footprint, avoidance, minimization, and mitigation measures shall be developed and implemented through consultation with the USFWS under Section 10 of the Federal Endangered Species Act (FESA) (or Section 7 as appropriate). At a minimum, mitigation measures will include the timing of construction activities outside of the breeding season (February 15 to August 31) and/or the purchase/conservation of offsite suitable habitat that is known to support CAGN at a minimum 1:1 ratio depending on the quality of habitat removed compared to the quality of habitat provided.

Prior to the issuance of grading permits and/or an action that would result in project site disturbance (whichever occurs first) (including but not limited to discing and demolition activities), the applicant shall submit to the satisfaction of the Development Services Director/Planning Division, evidence that focused clearance surveys have been completed t o determine the presence/absence of burrowing owls (BUOW). Pre-construction surveys for BUOW shall be required in accordance with protocols established by California Department of Fish and Wildlife (CDFW) before the start of grading activities to confirm t he absence of BUOW from the site. If the survey determine the BUOW to be present, protective measures shall be required to ensure compliance with the Migratory Bird Treaty Act and other applicable CDFW Code requirements and include, but are not limited to the following:

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-27
or incubation or 2) that juveniles from the occupied burrows are foraging independently and are capable of an independent survival flight.

• All relocation shall be approved by the CDFW. The permitted biologist shall monitor relocated owls a minimum of three days per week for a minimum of three weeks. A report summarizing the results of the relocation and monitoring shall be submitted to the CDFW within 30 days following completion of the relocation and monitoring of the BUOW.

• A BUOW Long-term Management Plan (LTMP) shall be prepared by a qualified biologist and submitted to the CDFW for review and approval prior to relocation of owls. The BUOW LTMP shall describe proposed relocation, biological monitoring, and long -term management. The plan shall include the number and location(s) of occupied BOUW sit es and details on suitable habitat at the receiver site selected and approved for relocation. The LTMP shall also describe specific procedures to compensate for impacts to BUOW/occupied burrows at the Project area. Such procedures may include, but are not limited to, the purchase/conservation of offsite suitable habitat that is known to support BUOW at a minimum 1:1 ratio depending on the quality of habitat removed compared to the quality of habitat provided. Specific ratios will be determined in consultati on with CDFW. Prior to the issuance of occupancy permits, the developer shall provide copies of applicable species mitigation agreements/permits to the Development Services Director/Planning Division.

BIO-4 Focused Plant Surveys
Prior to the issuance of g rading permits or and/or an action that would result in project site disturbance (whichever occurs first) (including but not limited to discing and demolition activities), the project applicant shall submit to the satisfaction of the Development Services Director/Planning Division, evidence from a qualified biologist that the project site does not contain suitable habitat for Plummer’s mariposa-lily or Parry’s spineflower. Should the project site be located within an area that does have potential for Plummer’s mariposa -lily or Parry’s spineflower, the applicant shall provide evidence that a focused plant survey for Plummer’s mariposa-lily and Parry’s spineflower has been conducted during the appropriate blooming season (generally May to July for Plummer’s mariposa-lily and April to June for Parry’s spineflower). If © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-28
the survey results are negative for the presence of Plummer’s mariposa-lily or Parry’s spineflower, then no further action is required.

If the surveys are positive for the presence of Plummer’s mariposa-lily or Parry’s spineflower, then their distribution and associated natural plant community shall be documented and a formal report submitted to the California Department of Fish and Wildlife. These data will then be used to determine the level of impact to each identified species from project development. Impacts on sensitive plants shall be mitigated offsite at a minimum 2:1 ratio. Conservation credits for each of these species can be purchased at an approved conservation bank such as the Cajon Creek Conservation Bank.

BIO-5 Riversidian Alluvial Fan Sage Scrub
Prior to the issuance of grading permits, the project applicant shall submit to the satisfaction of the Development Services Director/Planning Division, evidence that preservation o f RAFSS habitat with equal or better habitat value has been preserved at a suitable location where the long- term viability of the habitat can be assured. Satisfactory evidence includes, but is not limited to evidence that the appropriate amount (to be determined by the City of Rialto, the California Department of Fish and Wildlife [CDFW], and the project applicant) has been purchased at an approved mitigation bank, or that a long -term conservation plan has been developed and implemented as part of longe r-term mitigation strategy for multiple projects. Any long -term conservation plan must be presented to the City of Rialto and CDFW for review and comment as part of any needed incidental take permits.

2022 Amendment Project: The 2022 Amendment Project site consists of undeveloped but disturbed native habitats. The site supports disturbed and sparse chamise chaparral. At the time of the recent biological surveys, d ominant shrubs were chamise ( Adenostoma fasciculatum), holly -leaf cherry ( Prunus ili cifolia), California buckwheat (Eriogonum fasciculatum) and deerweed (Acmispon glaber); however, the actual density of shrubs was very low. Between the shrubs dominant species were brome grasses ( Bromus spp.), summer mustard (Hirschfeldia incana ) and red -stem filaree ( Erodium cicutarium). Less abundant species present included California sagebrush (Artemisia californica), California croton ( Croton californicus ), prickly pear cactus ( Opuntia sp.), common fiddleneck (Amsinckia menziesii) and brittlebrush (Encelia farinosa). © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-29
Wildlife was sparse due to the disturbed habitats and poor site conditions. Species detected were typical of disturbed and built -up areas and included western fence lizard (Sceloporus occidentalis), red-tailed hawk (Buteo jamaicensis), Common raven (Corvus corax) and California ground squirrel (Otospermophilus beecheyi).

No special status plant or wildlife species were detected at the site and there are no historic site records for any special status plant or wildlife species. Due to lack of suitable habitat, poor site conditions, small size and being surrounded by developed areas; the site has no suitable habitat for any special status plant or wildlife species and has no potential to support any special status species. Specifically , the Biological Surveys determined that the site has no suitable habitat for California gnatcatcher ( Polioptila californica), San Bernardino kangaroo rat ( Dipodomys merriami parvus ), burrowing owl (Athene cunicularia) or Parry’s spineflower (Chorizanthe parryi).

Based on the preceding, when compared to the Certified EIR findings, no new or substantially increased impacts to candidate, sensitive, or special status species would occur under the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures : None. Due to lack of suitable habitat, poor site conditions, small size and being surrounded by developed areas; the Project- specific Biological Surveys determined that the site has no suitable habitat for any special status plant or wildlife species and has no potential to support any special status species.

As such, Certified EIR Mitigation Measures BIO-1 through BIO-5 would not apply to the Amendment Project.

b, c) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: According to the Initial Study prepared for the Certified EIR, no riparian habitat, jurisdictional waters, including federally protected wetlands such as marsh, vernal pool, or coastal areas , or other sensitive natural community are present onsite. No impacts in this regard were identified, and no f urther analysis was included in the Certified EIR (Initial Study, pp. 30 – 31).

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-30
Certified EIR Mitigation Measures: None.

2022 Amendment Project : The site does not contain any rivers, creeks, streambeds, wetlands, vernal pools or riparian areas. There are no areas onsite that are subject to the jurisdiction to the US Army Corps of Engineers or California Department of Fish and Game. Based on the preceding, when compared to the Certified EIR findings, no new or substantially increased impacts to candidate, sensitive, or special status species would occur under the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

d) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR concluded that the 2016 RSPA could potentially impact migratory birds. Nesting birds are protected pursuant to the Migratory Bird Treaty Act and CDFW Fish and Game Code. In order to protect migratory bird species, the Certified EIR included Mitigation Measure BIO- 6, presented below, to reduce impacts to less-than-significant (Certified EIR, p. 4.3-18).

Certified EIR Mitigation Measures:

BIO-6 Migratory Birds
Prior to the issuance of grading permits and/or an action that would result in project site disturbance (whichever occurs first) (including but not limited to discing and demolition activities), the project applicant shall submit to the satisfaction of the Development Services Director/Planning Division, evidence that a preconstruction nesting bird survey has been conducted prior to any ground disturbing activities and removal of vegetation or other potential nesting habitat during the nesting period (generally February 1st to August 31st). If birds are found to be nesting inside or within 250 feet (500 feet for raptors) of the impact area, construction will need to be postponed, at the discretion of a qualified biologist, until it is determined that the nests are no longer active.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-31
2022 Amendment Project: No wildlife corridors or linkages are located onsite . Further, proximate urban development diminishes the site ’s potential to function as a wildlife movement corridor. Consistent with the conclusion of the Certified EIR, the biological surveys included updated mitigation to preclude impacts to nesting birds. On this basis, when compared to the Certified EIR findings, no new or substantially increased impacts to wildlife corridors, wildlife linkages, or wildlife movement would occur under the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures:

4-1 Impacts to nesting birds can be avoided and, compliance with the federal Migratory Bird Treaty Act of 1918 (MBTA) can be accomplished by the following:
• If possible, all vegetation removal activities shall be scheduled from August 1 to February 15, which is outside the nesting season. This would ensure that no active nests would be disturbed and that removal could proceed rapidly.
• If vegetation is to be cleared during the nesting season (February 15 to July 31), all suitable habitat will be thoroughly surveyed for the presence of nesting birds by a qualified biologist 72 hours prior to clearing. If any active nests are detected, the area shall be flagged and mapped on the construction plans along with a minimum 50-foot buffer and up to 300 feet for raptors, with the final buffer distance to be determined by the qualified biologist. The buffer area shall be avoided until the nesting cycle is complete or it is determined that the nest has failed. In addition, the biologist will be present on the site to monitor the vegetation removal to ensure that any nests, which were not detected during the initial survey, are not disturbed.

e, f) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study prepared for the Certified EIR determined that the 2016 RSPA would not conflict with any local policies or ordinances protecting biological resources. The Project site is located within the approved Renaissance Specific Plan. The Specific Plan area is zoned for urban development and is not included in a Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan. The Initial Study concluded t hat no © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-32
impact relative to local policies or adopted habitat conservation plans would occur , and no further analysis was included within the Certified EIR (Initial Study, pp. 30 – 31).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The 2022 Amendment Project would comply with local policies and ordinances protecting biological resources. The Project does not propose or require development or activities that would conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan. When compared to the Certified EIR findings, no new or substantially increased impacts to a Habitat Conservation Plan, Natural Community Plan, or other approved local, regional, or state habitat conservation plan would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

Certified EIR Conclusions: The Initial Study prepared for the Certified EIR concluded that implementation of the 2016 RSPA would not affect any site listed on a local, state, or National historical register. The potential for significant impacts to buried resources was determined to be low based on consultation with the Native American Heritage Commission (NAHC). However, Mitigation Measure CR-4 from the previously-certified 2010 Renaissance Specific Plan EIR, which require d monitoring of development-related excavation, was required during all construction-related ground disturbances occurring within the southern portion of the Specific Plan area.

According to the EIR prepared for the 2010 Renaissance Specific Plan, the Project site is not located within a known or suspected cemetery and there are no known human remains within the Project site. State law relating to the discovery of human remains provides guidance should human remains be discovered during construction; however, the likelihood of finding human remains is low and the resulting impact was considered less-than-significant (Initial Study, pp. 32-34).

Certified EIR Mitigation Measures:

CR-4 Monitoring of development-related excavation is required during all construction -related ground disturbances that take place along Baseline Road, Alder Avenue, Laurel Avenue, Locust Avenue, Linden Avenue and Maple Avenue in the southern portion of the project area.

Specifically, monitoring is recommended for the entire southern portion of the project area, from Baseline Road to a nort hern point marked by an east -west extension of Walnut Avenue. This is due to the high level of historic development in the southern portion of the project area, and the resultant high probability that significant, intact subsurface deposits would be found. These monitoring procedures shall be directed by the project archaeologist and discussed with the general contractor onsite before construction begins. Construction -related disturbances in the southern portion of the project area should be monitored on a full-time basis by a qualified cultural resource professional or the project archaeologist. Once 50 percent of the earth to be moved during grading © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-34
has been examined, the project archaeologist may, at his or her discretion, terminate monitoring if and only if no buried cultural resources have been detected. If buried cultural resource sites are detected during monitoring, no matter whether such resources are significant or not, monitoring must continue until 100 percent of the earth within the southern port ion of the project has been disturbed and inspected by the monitor(s). If sites are exposed during construction, they should be handled in the City of Rialto -Renaissance Specific Plan manner established in Mitigation Measures 5 -1 through 5 -3. This measure shall be implemented to the satisfaction of the City Development Services Director.

2022 Amendment Project: A site-specific Cultural Resources Assessment was conducted for the 2022 Amendment Project. In summary, there are no known or probable historic or archeological resources within the subject site. The records search data and field survey conducted as part of the Cultural Resources Assessment did not yield any cultural resources within the Amendment Project site boundaries. Conditions have failed to indicate sensitivity for buried cultural resources. As such, the Assessment concludes that no additional cultural resource work or monitoring is necessary for any earthmoving proposed within the site. However, should such resources be discovered during construction, a qualified archaeologist should be contacted to assess the find, as required by Mitigation Measure 5 -1, below. As mitigated, the potential for the 2022 Amendment Project to cause a substantial adverse chan ge in the significance of a cultural resource pursuant to Section 15064 is considered less-than-significant.

Potential adverse impacts to human remains are avoided through mandated compliance with California Health and Safety Code Section 7050.5, and Pub lic Resources Code Section 5097.98 and would therefore be less -than-significant. When compared to the Certified EIR findings, no new or substantially increased impacts to historic or archeological resources would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures:

5-1 If previously undocumented cultural resources are identified during earthmoving, a qualified archaeologist should be contacted to assess the nature and significance of the find, diverting construction excavation if necessary.

2022 Amendment Project:

Overview
CEQA Guidelines (Guidelines) Appendix F Energy Conservation establishes parameters and context for determining whether a project would result in the inefficient, wasteful, and unnecessary consumption of energy. CEQA Guidelines Section 15126.2 Consideration and Discussion of Significant Environmental Impacts, as amended December 28, 2018, recognizes the need to consider Guidelines Appendix F Energy Conservation when analyzing project impacts. In this regard, CEQA Guidelines Section 15126.2 (b), excerpted below, provides the following direction:

Energy Impacts. If analysis of the project’s energy use reveals that the project may result in significant environmental effects due to wasteful, inefficient, or unnecessary consumption use of energy, or wasteful use of energy resou rces, the EIR [MND] shall mitigate that energy use. This analysis should include the project’s energy use for all project phases and components, including transportation-related energy, during construction and operation. In addition to building code compli ance, other relevant considerations may include, among others, the project’s size, location, orientation, equipment use and any renewable energy features that could be incorporated into the project. (Guidance on information that may be included in such an analysis is presented in Guidelines Appendix F.) This analysis is subject to the rule of reason and shall focus on energy use that is caused by the project. This analysis may be included in related analyses of air quality, greenhouse gas emissions, transportation or utilities in the discretion of the lead agency.

The analysis presented here conforms to CEQA Guidelines Section 15126.2 (b) guidance.

In summary, the Project would provide for, and promote, energy efficiencies consistent with applicable state or federal standards and regulations. The Project would also conform to City of Rialto energy efficiency and energy conservation measures.

Existing Conditions

Electricity
The California Energy Commission (CEC) provides forecasts for electricity and n atural gas demand every two years as part of the Integrated Energy Policy Report (IEPR) process. The forecasts include 3 energy demand cases (low, mid, and high) designed to capture a reasonable range of demand outcomes over the next 10 years. The high energy demand case incorporates relatively high economic/demographic growth, relatively low electricity and natural gas rates, and relatively low committed efficiency program, self - generation, and climate change impacts. The low energy demand case includes lower economic/demographic growth, higher assumed rates, and higher committed efficiency program and self -generation impacts. The mid case uses input assumptions at levels between the high and low cases. The forecasts include estimates of the effects of new legislation and trends in electric consumption such as the use of zero -emission automobiles. IEPR data indicates relatively stable consumption rates from 2005 through 2018, with an increase in consumption beginning in 2020.

Southern California Edison (S CE) is the electrical utility provider for the City of Rialto .

SCE also provides information on energy efficiency, rotating outages, emergency preparedness, electrical safety tips, and tree planting guidelines to ensure non - interference with electrical utility lines.

Transportation Energy
California is home to 30 million registered cars, trucks, buses, and other motorized on - road vehicles. The state’s history has been, in part, a history of the automobile and the associated impacts on personal mobility, land- use planning, and air quality. In recognition of these challenges, California has enacted a suite of policies and goals to shift the transportation sector toward cleaner, sustainable fuels and more efficient technology vehicles. IEPR data indicates very stable consumption rates for jet fuel and diesel through 2030. Gasoline consumption is forecasted to decline through 2030.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-38
Natural Gas
Natural gas is an important energy source for California. Natural gas provides energy to heat homes, cook food, and generate electricity. Currently in California, natural gas serves more than 10.5 million homes, about 445,000 businesses, about 37,000 factories and industrial consumers, and more than 640 electric generating units. The greatest consumers of natural gas in decreasing order are electric power generation, residential, industrial, mining, commercial, and other. IEPR data generally shows a decreasing reliance on natural gas through 2024. The CEC indicates increased reliance on natural gas for power generation between 2024 and 2026 due to expiration of long- term power supply contracts (purchase agreements) with coal facilities outside California.

Southern California Gas Company (SoCalGas) provides natural gas to the City of Rialto.

SoCalGas also provides customers with appliance services, an energy efficiency and rebate program, and information on emergency preparedness and air quality.

Project Energy Consumption
Construction and operational energy consumption estimates of the 2022 Amendment Project are summarized below.

Construction Energy Consumption
Sources of Project construction energy consumption include: electrical energy consumed during construction, fuel consumed by construction equipment, and fuel consumed by employees and vendors. Construction is assumed to last 11 -months. Table 6-1 identifies the construction energy consumption of the 2022 Amendment Project.

Table 6-1
Construction Energy Consumption
Electrical Energy Consumption 28,801 kWh
Fuel Consumed by Construction Equipment 20,562 gallons
Fuel Consumed by Employees 6,919 gallons
Fuel Consumed by Vendors 4,043 gallons

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-39
Project construction activities would comprise temporary, single -event demands for diesel fuel and electricity and would not require on -going or permanent commitment of fuel for these purposes.

Operational Energy Consumption
Table 6-2 identifies the operational energy consumption of the 2022 Amendment Project.

Table 6-2
Operational Energy Consumption
Vehicle Energy Consumption 263,702 gallons of fuel/year Natural Gas Usage 235,683 kBTU/year
Electricity Demand 277,475 kWh/year

Summary
The 2022 Amendment Project would be required to comply with incumbent performance standards established under the Building Energy Efficiency Standards contained in the California Code of Regulations (CCR), Title 24, Part 6 (Title 24, Energy Efficiency Standards). Additionally, t he discussion at IS/MND Checklist Item 8 , Greenhouse Gas Emissions, summarizes Project consistency with the City of Rialto Climate A daptation Plan, which acts to reduce energy consumption and thereby minimize GHG emissions.

These same me asures comprise state and local plans for renewable energy or energy efficiency that would be applicable to the 2022 Amendment Project. As substantiated at IS/MND Checklist Item 8, Greenhouse Gas Emissions, the 2022 Amendment Project would not conflict with or obstruct a state or local plan for renewable energy or energy efficiency.

Further, developers and owners/tenants have vested financial incentives to avoid imprudent energy consumption practices. In this regard, there is growing recognition among developers and owners/tenants that efficient and sustainable construction and operational practices yield both environmental and economic benefits. On this basis, the Project would not result in or cause wasteful, inefficient, and unnecessary consu mption of energy.

Substantiation: Geology and soils impacts of the 2022 Amendment Project, as discussed below, are summarized in part from Geotechnical Investigation, Proposed Warehouse, NWC Locust Avenue and Renaissance Parkway Rialto, California (Southern California Geotechnical) January 3, 2022. The Geotechnical Investigation is presented in its entirety at Addendum Appendix D.

a, i) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: According to the Initial Study prepared for the Certified EIR, the site is not located within a State of California designated Alquist -Priolo Earthquake Fault Zone or a County of San Bernardino designated Earthquake Fault Zone; and therefore, is unlikely to be subject to surface rupture during an earthquake. While nearby faults are capable of producing severe earthquakes, the Initial Study determined that the site is located outside mapped fault zones and therefore impacts would be less -than- significant (Initial Study, p. 36).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: Based on the information presented in the Geotechnical Investigation, the site is not located within a State of California designated Alquist-Priolo Earthquake Fault Zone , and no evidence of faulting was identified. The Investigation determined that the possibility of significant fault rupture on the site is considered low.

When compared to impacts addressed in the Certified EIR, no new or substantially increased impacts would occur under the 2022 Amendment Project (Geotechnical Investigation, p. 9).
© 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-42
2022 Amendment Project Mitigation Measures: None.

a, ii) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study prepared for the Certified EIR relied on the 2010 Renaissance Specific Plan EIR and the mitigation presented in this regard. In summary, given the nature of nearby active faults, their historic seismicity, and their distance to the site, the potential for strong seismic ground shaking was identified as a potentially significant impact. For that reason, the 2010 Renaissance Specific Plan EIR identified a number of mitigation measures that would be effective in reducing the severity of the impact to less-than-significant.

Certified EIR Mitigation Measures:

GS-1 Prior to the issuance of grading permits for each planning area of the project, the project applicant or its designee shall provide design -level geotechnical reports for those areas. These reports shall consider, but shall not necessarily be limited to, such factors as manufactured slope stability (if applicable), compressible soils, corrosive soils, and the engineering and construction of occupied or inhabited structures. The findings and recommendations contained in these reports shall be implemented.

As necessary, the City may require additional studies and/or engineering protocols to meet its requirements. This measure shall be implemented to the satisfaction of the City Development Services Director.

GS-2 Prior to the issuance of building permits for each planning area of the project, the project applicant or its designee shall demonstrate that all occupied or inhabited structures will be able to withstand a horizontal seismic acceleration of 0.96g. Specific de sign-level geotechnical reports shall be prepared by a State of California Certified Engineering Geologist for planning areas within the Specific Plan to determine that structures within those areas meet required design criteria.

This measure shall be implemented to the satisfaction of the City Development Services Director.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-43
GS-3 Prior to the issuance of building permits for each planning area, the project applicant or its designee shall demonstrate that all occupied or inhabited structures will be constructed to the standards outlined in the Uniform Building Code, the California Building Code, the design -level geotechnical reports, and/or other such standard as identified and required by the City. This measure shall be implemented to the satisfaction of the City Development Services Director.

2022 Amendment Project: The Project site is located in the seismically active Southern California region and is prone to earthquakes, which may result in hazardous conditions affecting people and structures within the region. Per Chapter 5 of the City of Rialto General Plan, the San Jacinto, San Andreas, and Cucamonga faults have the potential of generating earthquakes of maximum magnitudes ranging from 6.7 to 8.0. However, seismic events and associated ground motion can affect a widespread area. The potential severity of ground shaking depen ds on many factors, including distance from the originating earthquake fault, the earthquake magnitude, and underlying soil conditions.

Although implementation of the 2022 Amendment Project has the potential to result in the exposure of people and structu res to strong ground shaking during a seismic event, this exposure is no greater than exposure present in other areas throughout the Southern California region. Additionally, as part of the City’s standard review and approval of development projects, the P roject would be required to comply with Uniform Building Code (UBC) and California Building Code (CBC) seismic safety design and engineering requirements. Design and construction of the 2022 Amendment Project in accordance with UBC and CBC requirements minimizes potential adverse impacts of seismic events as they may affect the site . All Project final plans would be required to incorporate design- and site -appropriate means to avoid or minimize effects of fault rupture or seismic shaking events.

Based on the preceding, the potential for the Project to cause potential substantial adverse effects, directly or indirectly, including the risk of loss, injury, or death involving strong seismic ground shaking is considered less- than-significant. When compared to impacts addressed in the Certified EIR, no new or substantially increased impacts would occur under the 2022 Amendment Project.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-44
2022 Amendment Project Mitigation Measures: Although no Project-specific mitigation is necessary for the Amendment Project, Certified EIR Mitigation Measures GS-1 through GS-3 are carried forward in this Addendum.

a, iii) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study prepared for the Certified EIR determined that, although liquefaction potential is high in many parts of Southwest San Bernardino County, the potential for it to occur within the Specific Plan area is considered low .

According to the EIR prepared for the 2010 Renaissance Specific Plan, the site is not in an area identified by San Bernardino County or the California Geological Survey as being susceptible to liquefaction. This is largely due to the depth to groundwater in the area and the dryness of the soils. For these reasons, impacts related to liquefaction were considered less-than-significant (Initial Study, p. 36).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The Geotechnical Investigation indicates that the site is not located within an area of liquefaction susceptibility. Based on the mapping performed by the County of San Bernardino, and the lack of a historic high ground water table within the upper 50± feet of the ground surface, the potential for liquefaction is considered less- than-significant (Geotechnical Investigation, p. 11) . When compared to impacts addressed in the Certified EIR, no new or substantially increased impacts would occur under the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

a, iv) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Specific Plan area is generally relatively flat; as such, the Initial Study concluded that impacts from naturally occurring landslides are considered negligible. However, given the site’s loose, coarse, and dry soil, slope failure can also occur on manufactured and temporary slopes, which are formed during excavations of © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-45
soil for utility lines, trenches, etc. For these reasons, slope failure from manufactured and temporary slopes was considered potentially significant and require d mitigation to reduce the potential effect to less -than-significant. Implementation of mitigation identified in the previously-certified EIR would reduce this potentially significant impact to a level of less-than-significant.

Certified EIR Mitigation Measures:

GS-4 During construction and excavation activities on the project site, all temporary slopes (i.e., excavations and trenching) shall be adequately shored and/or flattened to a shallower gradient to lessen the possibility of failure. All Cal- OSHA regulations shall be implemented for excavations that will be entered by people. All excavations will be open only as long as is necessary and shall be backfilled immediately upon completion of work. This measure shall be implemented to the satisfaction of the City Development Services Director.

2022 Amendment Project: The topography of the site has not changed since the preparation of the Certified EIR, precluding the risk of landslide. The Project-specific Geotechnical Investigation includes detailed design, grading, and construction specifications to preclude impacts in this regard. The 2022 Amendment Project would comply with all recommendations of the Geotechnical Investigation, and impacts would be less-than-significant.

2022 Amendment Project Mitigation Measures : None. The recommendations of the Project-specific Geotechnical Investigation prepared for the Amendment Project shall replace Certified EIR Mitigation GS-4.

b) No Changes or New Information Requiring Preparation of an MND or EIR.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-46
elements. Mitigation Measures G S-5 and GS-6 would preclude potentially significant impacts in this regard.

Certified EIR Mitigation Measures:

GS-5 Prior to the issuance of grading permits, the project applicant or its designee shall present an Erosion Control Plan (ECP) designed to lessen the impacts of erosion during construction. This plan shall comply with all applicable grading codes and water quality protection protocols. This plan shall be implemented during site construction. This measure shall be implemented to the satisfaction of the City Development Services Director.

GS-6 During grading and development of the project site, all oversized material (larger than 12 inches in largest dimension) shall be handled as recommended in the project geotechnical reports.

This material may be placed in deeper fills, nonstructural areas, or disposed of offsite. This measure shall be implemented to the satisfaction of the City Development Services Director.

2022 Amendment Project: Project construction a ctivities would temporarily expose underlying soils, thereby increasing their susceptibility to erosion until the 2022 Amendment Project is fully implemented. Potential erosion impacts incurred during construction activities are mitigated below the level of significance through the Project’s mandated compliance with a City -approved Storm Water Pollution Prevention Plan (SWPPP) and compliance with SCAQMD Rules that prohibit grading activities and site disturbance during high wind events. At Project completio n, potential soil erosion impacts in the area will be resolved, as pavement, roads, buildings, and landscaping are established, overcovering previously exposed soils.

The Project involves construction of conventional light industrial land uses and supporting site improvements within an essentially level area of the City. The Project does not propose to significantly alter existing topography. Any required cut/fill within the Project area will establish suitable building pads and facilitate efficient site drainage, consistent with the recommendation s of the Geotechnical Investigation . Based on the preceding, potential impacts associated with erosion or changes in topography are considered less-than-significant.

2022 Amendment Project Mitigation Measures: Although no Project-specific mitigation is necessary for the Amendment Project, Certified EIR Mitigation Measure GS-5 is carried forward in this Addendum. Measure GS-6 is replaced by the recommendations of the Project-specific Geotechnical Investigation prepared for the Amendment Project.

c) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: No effects related to the geologic unit or soils, including the potential for occurrence of on - or off -site landslides, lateral spreading, subsidence, liquefaction, or collapse have been identified.

The Initial Study concluded that conformance with a NPDES General Construction Activity Storm Water Permit, and implementation of a General Construction Activity Storm Water Permit (and associated SWPPP), would also help to avoid or reduce potential short-term erosion and sedimentation impacts to a level of less-than-significant (Initial Study, p. 37).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: No effects related to the geologic unit or soils, including the potential for occurrence of on - or off -site landslides, lateral spreading, subsidence, liquefaction, or collapse have been identified (Geotechnical Investigation, p. 11).

As with the 2016 RSPA, conformance with a NPDES General Construction Activity Storm Water Permit, and implementation of a General Construction Activity Storm Water Permit (and associated SWPPP), would help to avoid or reduce potential short -term erosion and sedimentation impacts to a level of less-than-significant. When compared to impacts addressed in the Certified EIR, no new or substantially increased impacts would occur under the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-48
d) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: According to the Initial Study prepared for the Certified EIR, soils in the Specific Plan area exhibit few of the characteristics typical of expansive soils and have a very low expansive potential. The Initial Study concludes that no impacts relative to expansive soils would occur (Initial Study, p. 37).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: Near-surface soils consist of silty sands with no appreciable clay content. These materials have been visually classified as non -expansive (Geotechnical Investigation, p. 12). As such, no significant impacts due to expansive soils have been identified. When compared to impacts addressed in the Certified EIR, no new or substantially increased impacts would occur under the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

e) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial S tudy determined that no septic tanks or alternative wastewater disposal systems would be used as part of the 2016 RSPA. As a result, no impacts were identified (Initial Study, p. 37).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The 2022 Amendment Project would connect to the City sanitary sewer system. No septic tanks or other alternative wastewater disposal systems are proposed. On this basis, the 2022 Amendment Project would not result in any impacts related to on -site or alternative wastewater disposal systems. The 2022 Amendme nt Project would therefore not result in new, additional, or different impacts regarding use of alternative wastewater treatment systems not considered and addressed in the Certified EIR.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-49
2022 Amendment Project Mitigation Measures: None.

f) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study states:

“…the project area is located primarily upon Quaternary younger alluvial fan deposits of Holocene or historically recent age. This Holocene alluvium has low potential for significant fossil deposits and is thereby assigned low paleontological sensitivity. However, these Holocene sediments may overlie earlier deposits that are also present in portions of the project area near the easte rn boundary, in the vicinity of the proposed Project. These deposits have been mapped alternatively as either middle to later Pleistocene fan deposits or middle to later Pleistocene aeolian (wind created) dune sands. The most recent assessment has interpre ted these sediments as aeolian in nature, and has assigned the deposits an undetermined paleontological sensitivity. Thus, it can be concluded that the project area has both a low and undetermined probability of containing significant paleontological resources.” (Initial Study, p. 34).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: Potential paleontological resources impacts were discussed within the Cultural Resources Assessment prepared for the 2022 Amendment Project.

The Assessment states:

“The geologic units underlying this project are mapped entirely as alluvial sand and gravel deposits dating from the Holocene period (Dibblee & Minch, 2003). Holocene alluvial units are considered to be of high preservation value, but material found is unlikely to be fossil material due to the relatively modern associated dates of the deposits. However, if development requires any substantial depth of disturbance, the likelihood of reaching Pleistocene alluvial sediments would increase. The Western © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-50
Science Center does not have localities within the project area or within a 1- mile radius.

While the presence of any fossil material is unlikely, if excavation activity disturbs deeper sediment dating to the earliest parts of the Holocene or Late Pleistocene periods, the material would be scientifically significant.

Excavation activity associated with the development of the project area is unlikely to be paleontologically sensitive, but caution during development should be observed.”

The Amendment Project does not propose disturbance at atypical depths , nor does the Cultural Resources Assessment recommend full -time construction paleontological monitoring. However, out of an abundance of caution, Mitigation Measure 7 -1 requires a pre-construction meeting to discuss protocol should resources be discovered during construction of the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures:

7-1 A qualified paleontologist should be retained to conduct a pre -construction meeting prior to ground disturbance to instruct workers on proper fossil identification and subsequent notification of a trained professional. If paleontological resources (fossils ) are discovered during Project grading, work would be halted in that area until a qualified paleontologist can be retained to assess the significance of the find. The P roject paleontologist would monitor remaining earthmoving activities at the P roject sit e and would be equipped to record and salvage fossil resources that may be unearthed during grading activities. The paleontologist would be empowered to temporarily halt or divert grading equipment to allow recording and removal of the unearthed resources. Any fossils found would be evaluated in accordance with the CEQA Guidelines and offered for curation at an accredited facility approved by the City. Once grading activities have ceased or the paleontologist determines that monitoring is no longer necessary, monitoring activities would be discontinued.

Substantiation:

To assess the potential impacts of the 2022 Amendment Project, a Project -specific Greenhouse Gas Analysis ( Orbis Rialto II, Greenhouse Gas Analysis, City of Rialto [Urban Crossroads, Inc.] January 20, 2022) has been prepared. The Greenhouse Gas Analysis is presented in its entirety as Appendix E to this Addendum.

a) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR determined that, although the 2016 RSPA would result in exceedances of applicable GHG thresholds, no new impacts beyond those identified within the 2010 Renaissance Specific Plan EIR would occur and no mitigation was proposed (Certified EIR, pp. 4.4-12 – 4.4-23).

As shown above, the 2022 Amendment Project would result in a total of 2,880.65 MTCO
2e/yr. As such, the Amendment Project would not exceed the SCAQMD/City’s screening threshold of 3,000 MTCO2e/yr (as presented within the GHG Analysis).

Based on the preceding, the Project would not have the potential to generate direct or indirect GHG emissions that would result in a significant impact on the environment.

When compared to the Certified EIR analys is, no new or substantially increased GHG emissions impacts would occur under the 2022 Amendment Project.

GHG-1 Prior to the issuance of a building permit, the project applica nt must submit to the satisfaction of the Development Services Director/Planning Division, evidence that the proposed Renaissance Marketplace and Planning Area 108 projects comply with and would not conflict with or impede the implementation of reduction goa ls identified in Assembly Bill (AB) 32, the Governor’s Executive Order (EO) S -3-05, and other strategies to help reduce greenhouse gases (GHGs) to the level proposed by the Governor. The Renaissance Marketplace and Planning Area 108 projects will be design ed and constructed to incorporate and/or implement to the extent feasible and to the satisfaction of the City, the following measures:

Construction and Building Materials.
• Use locally produced and/or manufactured building materials for at least 10 percent of the construction materials used for the Projects.
• Recycle/reuse at least 50 percent of the demolished and/or grubbed materials (including, but not limited to, soil, vegetation, concrete, lumber, metal, and cardboard) if feasible. • Use “Green Building Materials,” such as those materials that are resource efficient and are recycled and manufactured in an environmentally friendly way, for at least 10 percent of the Projects.

Energy Efficiency Measures.
• Design all project buildings to meet or exceed the California Building Code’s (CBC) Title 24 energy standard, including, but not limited to, any combination of the following:
o Increase insulation such that heat transfer and thermal bridging is minimized; o Limit air leakage through the structure or within the heating and cooling distribution system to minimize energy consumption; and o Incorporate ENERGY STAR or better rated windows, space heating and cooling equipment, light fixtures, appliances, or other applicable electrical equipment. • Install efficient lighting and lighting control systems. Use daylight as an integral part of the lighting systems in buildings.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-54
• Install “cool” roofs and cool pavements.
• Install energy -efficient heating and cooling systems, appliances and equipment, and control systems.
• Install solar lights or light-emitting diodes (LEDs) for outdoor lighting or outdoor lighting that meets the City of Rialto City Code.
• Install solar photovoltaic or other technology to generate electricity on -site to reduce consumption from the electrical grid.
• Install electrical vehicle charging stations to promote the use of electrical vehicles. • Promote and incentivize solar installations on new warehouse space through partnerships with SCE and other private sector funding sources including Sungevity, SolarCity, a nd other solar lease or PPA companies.
• Establish a goal that a percentage of new warehousing projects install solar to provide a minimum of 25 percent of the project’s new on -site energy needs and that all existing warehousing install solar to provide a minimum of 25 percent of power needs with solar.

This goal could be supported through nonfinancial incentives or streamlined permitting.

Cities may also act as a resource for connecting project proponents with funding opportunities.

Water Conservation and Efficiency Measures.
• Devise a comprehensive water conservation strategy appropriate for the Project and its location. The strategy may include the following, plus other innovative measures that may be appropriate:
o Create water-efficient landscapes within the development. o Install water-efficient irrigation systems and devices, such as soil moisture-based irrigation controls.
o Use reclaimed water, if available, for landscape irrigation within the Project. Install the infrastructure to deliver and use reclaimed water, if available. o Design buildings to be water- efficient. Install water -efficient fixtures and appliances, including low-flow faucets and waterless urinals. o Restrict watering methods (e.g., prohibit systems that apply water to non-vegetated surfaces) and control runoff.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-55
Solid Waste Measures.
• To facilitate and encourage recycling to reduce landfill-associated emissions, among others, the Projects will provide trash enclosures that include additional enclosed area(s) for collection of recyclable materials.
• The recycling collection area(s) will be located within, near, or adjacent to each trash and rubbish disposal area. The recycling collection area will be a minimum of 50 percent of the area provided for the trash/rubbish enclosure(s) or as approved by the waste management vendor for the City of Rialto.
• Provide employee education on waste reduction and available recycling services.

Transportation Measures.
• To facilitate and encourage nonmotorized transportation, bicycle racks shall be provided in convenient locations to facilitate bicycle access to the Project area. The bicycle racks shall be shown on building plans submitted for Planning Department approval and shall be installed in accordance with those plans.
• Provide pedestrian walkway and connectivity requirements. • All new non -residential and multifamily developments of ten or more units shall be designed to incorporate the transportation control measures (TCM) described in Chapter

18.59 of the City of Rialto Municipal Code.

2022 Amendment Project: Pursuant to 15604.4 of the CEQA Guidelines, a lead agency may rely on qualitative analysis or performance-based standards to determine the significance of impacts from GHG emissions. As such, the GHG A nalysis evaluated Project consistency with SB 32 (2017 Scoping Plan), General Plan Measures, and the City of Rialto Climate Adaptation Plan to assess impacts in this regard.

The GHG Analysis concluded that the Project would not conflict with any of the 2017 Scoping Plan elements. Additionally, t he Climate Adapt ation Plan provides general guidance and policies that are designed to prepare the City and its residents for the expected impacts of climate change. The Project would comply with and would implement State and regional regulations and strategies that would minimize and control GHG emissions, and in this regard supports the City’s Climate Adaptation Plan.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-56
On this basis, the 2022 Amendment Project would not conflict with plans, policies, and regulations adopted for the purpose of reducing GHGs. The 2022 Amendment Project would therefore not result in new, additional, or different impacts regarding consistency with applicable GHG emissions reduction plans, policies, and regulations not considered and addressed in the Certified EIR.

2022 Amendment Project Mitigation Measures: Although no Project-specific mitigation is necessary f or the Amendment Project, Certified EIR Mitigation Measure GHG- 1 is carried forward in this Addendum.

Substantiation: Potential hazards of the 2022 Amendment Project, as discussed below, are summarized in part from Phase I Environmental Site Assessment , Rialto II , NWC of Renaissance Parkway & Locust Avenue, Rialto, California 92376 (EBI Consulting) December 21, 2021. The Phase I ESA is presented in its entirety at Addendum Appendix F.

a) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: Known or suspected hazardous materials have been identified within the Specific Plan area in connection with past Rialto Airport operations.

The Initial Study prepared for the Certified EIR concluded that a potentially significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials would be mitigated to a level of less -than-significant with © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-58
implementation of mitigation measures identified in the EIR prepared for the 2010 Renaissance Specific Plan (Initial Study, p. 41).

Certified EIR Mitigation Measures:

HAZ- 1 Remediation of Contaminated Soils
The remediation of soils containing Chemicals of Concern (COCs) at concentrations exceeding the residential or industrial screening level shall meet the Cleanup Plan Removal Goals for Soils as depicted in Table 4.7 -4. This measure shall be implemented to the satisfaction of the Development Services Director.

Soil Remediation Areas
The locations where COCs have been identified for potential soil removal or onsite relocation (i.e., COCs above applicable cleanup goals listed in Table 4.7 -4)) are described below. The endangerment control measures as described in the Draft Cleanup Plan (TTI 2010) shall be applied during the soil removal or onsite relocation process.

Soil Excavation Areas
The locations where COCs have been identified for potential soil excavation to achieve the Remediation Goals for future residential and industrial development are described below.

1. The potential excavation of approximately 560 tons of impacted soil containing TPH-g from discrete areas along the sand drag race course located on Property B;

2. Potential excavation of approximately 6,430 tons of impacted soil contai ning PCBs, PAHs, and/or TRPH from areas along the alpha and bravo taxiways and north -south and east-west runways on Property C;

3. Potential excavation of approximately 6,300 tons of impacted soil containing PAHs and TRPH from WeCare Charities on Property D; (Removal of the top 1.5 feet of the entire site is proposed for removal since samples were only collected in visibly stained areas where accessible (no vehicles present). It is likely that the inaccessible areas (vehicle occupancy) contain similar levels of contamination in soils.)

4. Potential excavation of approximately 110 tons of impacted soil containing TRPH from E & M Aircraft Painting on Property D.
© 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-59

5. Potential excavation of approximately 30 tons of impacted soils containing TRPH from Rialto Aircraft Services on Property D;

6. Potential excavation of approximately 70 tons of impacted soil containing cadmium from West-Pac Restorations on Property D;

The calculated soil volumes for potential excavation on properties B, C and D combined is approximately 13,485 tons.

The excavation and removal of USTs from Mercy Air Services, Art Scholl Aviation, and the San Bernardino County Sheriff’s Department of Aviation will be addressed separately from the Site Characterization Report and Cleanup Plan because the USTs are currently being used for on - going business operations and they will be removed and remediated through the local regulatory agency prior to redevelopment of the Site.

Remediating Strategy for Soil
Chemicals of concern (COCs) above cleanup goals will be excavated, segregated and managed by either relocating soils onsite and/or offsite for disposal at an appropriate disposal facility:

HAZ-1(a) Excavation and Stockpiling Management
The excavated materials will be segregated based upon type (e.g. tarmac, pavement, and soil) and will be temporarily stockpiled onsite for loading, transport and disposal to an offsite facility, or onsite management, as provided under the Cleanup Plan. Soil excavated will be placed in separate stockpiles based on the COC present in soil. For instance, soil containing PAHs shall be placed in a separate stockpile from soil containing TRPH and PCBs. The exception to this procedure will be in the case when soil excavated contains multiple constituents (e.g. PAHs/TRPH ). In this case, soil containing multiple constituents shall be segregated accordingly based on the constituents present in soil (e.g. soil containing PAHs/TRPH shall be placed in a separate stockpile from soil containing TRPH/PCBs). The excavated soils ma y be further segregated based on field observation, and field monitoring results. All potentially contaminated soils excavated will be hauled offsite for disposal or relocated and contained onsite.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-60
HAZ-1(b) Offsite Disposal of Excavated Soil
All excavated soils to be exported offsite will be transported to an appropriately permitted licensed treatment, storage, and disposal facility (TSDF) for disposal. Potential disposal facilities include TRS (located in Azusa, California) TPS Technologies (located in Adelanto, California) or Western Environmental (located in Mecca, California.

All transportation activities will be performed in strict compliance with regulations and ordinances. The hauling contractor(s) used to transport contaminated soils will be fully licensed and permitted by the USEPA and the State of California. All Department of Transportation (DOT) and California Highway Patrol (CHP) safety regulations will be strictly followed.

Transportation equipment will be chosen to safely transport the expected volumes of soil, taking into consideration the types of roads to be traveled and their loading capacity. Routine truck maintenance and repairs will be performed at the remediation contractor’s premises prior to picking up loads of waste from the Site. The remediation contractor will be required to clean up, to the satisfaction of the regulatory agencies involved, any spills resulting from maintenance of the trucks due to road accidents during operation of this project. All vehicles, trailers, and containers of the subcontractors will be inspected by CRWQCB and/or San Bernardino County and contractor personnel on a routine basis.

Trucks will use only pre- planned and authorized routes, as approved by the City of Rialto, California. A detailed log of the loads hauled from the Site will be maintained in the Site field logbook. The log will include, at a minimum, the date and time trucks were loaded and off-loaded, the destination, size (volume and weight) of the load, description of the contents, name and signature of the hauler, and name and signature of the Contractor’s representative. The waste will be off -loaded for disposal in a manner consistent with current Federal EPA, State, and local regulations.

Trucks for the offsite transportation of contaminated soil will remain on clean areas at all times to minimize the need to decontaminate the truck tires. During loading, dust, and odor emissions will be monitored and mitigated as necessary accord ing to discussions earlier in this section. The hauling trucks will be equipped to fully cover all soils during transportation. At a minimum, the © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-61
soils will be tightly covered by a heavy tarp. Trucks hauling soils will be developed prior to the initiation of remedial efforts.

HAZ-1(c) Onsite Relocation of Excavated Soil
All excavated soil to be relocated onsite, with the exception of soils affected by TPH -g at concentrations in excess of Cleanup Goals may be placed beneath publicly -owned streets, from edge of curb to edge of curb within in public right of way, Figure 20. The relocation cells will be sized and excavated based on the estimated quantities of the removal areas. Further, individual relocation cells will be completed to accommodate soil based on the COC present in the soil stockpile. For instance, soil containing PAHs will be placed in a dedicated relocation cell designed to contain soils contaminated with PAHs. In the case when soil is contaminated with multiple constituents (e.g. PAHs/TRPH), these soils shall be placed in a dedicated relocation cell designed to contain these types of soils (e.g. soil containing PAHs/TRPH shall be placed in a relocation cell separate from soil containing TRPH/PCBs). The soil excavated during construction of th e relocation cells will be temporarily stockpiled onsite for subsequent reuse and for cover of the relocation cell. Upon excavation, the soil from the relocation cells will be transported to a staging area for stockpiling and subsequent sampling and analysis.

The location(s) for the proposed relocation cell(s) will be constructed using appropriate excavation techniques, such as sloping the excavation sidewalls at a 45 -degree angle or benching to ensure slope stability is maintained and the trenching is con ducted in accordance with Cal -OSHA regulations regarding trenches. Land-use restrictions will be applied to the areas of the roadways which include the relocation cells. Impacted soil will be placed in the cells at a minimum of 2 feet below the lowest utility main which is estimated to be between 7 and 10 feet bgs, and clean backfill will be placed between the ground surface and the top of the remediation cell. Backfill and compaction will be conducted appropriately.

The placement of clean backfill above the relocation cell allows for the installation and maintenance of the proposed subgrade utility alignments within the area of the relocation cells without disturbing the relocated affected soil. The proposed utilities to be installed include storm drain, sanitary sewer, joint trench (i.e., electrical, telephone, cable), and water. A typical relocation cell cross section is shown on Figure 20. The final site of the relocation cell(s) is subject to revision upon the written approval of CRWQCB staff. The engin eered design and specifications of the © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-62
relocation cell(s) will be determined through discussions with the RDA. The engineered design and specifications will be provided to CRWQCB staff for approval.

A geotextile fabric will be placed over the top of the affected soil to mark the interface between the clean backfill soil and the relocated affected soil. The geotextile will be extended along the edges of the right of way. The soil above the relocation cell(s) will be capped with road base material following placement and compaction of the clean backfill material. Asphaltic concrete pavement, curbs and gutters will be constructed during redevelopment of the Site. Placing the soil beneath publicly-owned city streets, separate from the rest of the developme nt project, will allow unrestricted use of the unaffected portions of the development, which will be separately parceled.

HAZ-1(d) Excavation of Tarmac and Base Aggregate Material The tarmac and base material down to native soil on Property C will be remo ved and the exposed native soil surface will be examined for discoloration and observation of chemical odor originating from the surface/subsurface. Areas exhibiting staining or a chemical odor will be included as part of the confirmation sampling program. It is intended that the tarmac paving be recycled and used in asphalt or as fill material onsite or offsite as part of a value engineering program. The tarmac could also be used onsite as aggregate base beneath streets and parking lots. Alternatives for onsite reuse of the aggregate material include the construction of landscape berm(s), placement of such material in below grade pits in dedicated areas of the Site that will be used as parkways, parks, and landscaping will also be an option. Implementation of these alternatives will control any potential exposure for future receptors, and will require a land-use restriction, including: (1) excluding use of the subject area for residential, hospital, schools or day care facility use; (2) requiring Regional Board notification prior to disturbance of such relocated tarmac or aggregate base materials.

HAZ-2 Confirmation Sampling and Analysis
Confirmation sampling shall be collected following excavation activities and prior to backfilling as described in the Conf irmation Sampling and Analysis Plan. All sampling activities shall be conducted in accordance with the approved Field Sampling Plan (FSP) prepared by the primary contractor. This measure shall be implemented to the satisfaction of the Development Services Director.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-63
HAZ-3 Contingency Plan for Further Remedial Action
To minimize the potential for exposure of construction personnel to unknown contaminated soil during excavation and grading activities, prior to initiating construction or soil disturbance activities and to address the contingency of the discovery of unknown hazardous materials, a Site Management Plan (SMP) will be developed and provided to construction contractors that summarizes applicable legal requirements regarding the disco very, reporting, management, and disposal of hazardous materials or hazardous wastes. Contractors will also be obligated to comply with applicable legal requirements. The SMP shall be prepared and implemented by a qualified environmental firm that has a re gistered civil engineer, a registered geologist, or a registered environmental assessor on their staff, and shall be subject to review and approval by the County of San Bernardino. As a component of the SMP, a contingency plan shall be prepared that shall identify parameters and physical observations that indicate potential hazardous materials contamination, including soil discoloration, suspicious odors, presence of underground storage tanks, or buried building material, including asbestos containing material. This contingency plan shall include measures to protect worker safety if signs of contamination are encountered, identify sampling and analysis protocols for various substances that might be encountered (e.g., volatile organic compounds, petroleum hydrocarbons, heavy metals, asbestos), and list required regulatory agency contacts if contamination is found. Such worker safety measures may include use of personal environmental protection equipment, 40 hour HAZWOPER training, and use of real time monitoring devices. The SMP document shall specify procedures for sampling and profiling of soils, consistent regulatory requirements, prior to transport and disposal, and procedures for groundwater waste management.

HAZ-4 Groundwater Use
The drilling of new wells or the use of existing wells shall be prohibited within the Specific Plan area, except for those purposes that will not harm the public or create environmental impacts related to perchlorate contamination. This measure shall be implemented to the satisfaction of the Public Works Director/City Engineer.

HAZ-5 Hazards Associated with Illegal Fenceline Dumping at the Site's Western Edge Materials from the western portion of the Site will be removed and observed for evidence of recognized environmental conditions. If such conditions are identified, sampling will be performed to confirm the absence (or presence) of contaminants in soil to determine if further action is © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-64
required. Any remedial actions necessary will be undertake consistent with contingency plans as identified under mitigation measure HAZ-3 of this section.

HAZ-6 Underground Pipeline
Any development located immediately adjacent to the existing easement for the underground gas pipeline will require coordination between the contrac tors and the easement holder to establish a monitoring program.

HAZ-7 Pre-Demolition Activities
Prior to approval of demolition by the Development Services Department, an asbestos survey will be conducted prior to demolition of applicable structures pursu ant to state and federal law. All asbestos containing building materials will be removed prior to structure demolition. This work will be performed by an abatement contractor who is certified by the California OSHA Division of Occupational Safety and Healt h (DOSH) with properly trained and registered workers. All abatement techniques will be in accordance with DOSH and EPA protocol and also in conformance with South Coast Air Quality Management District rules. All removed asbestos containing building materials will be properly disposed of at a landfill certified to accept asbestos waste and waste will be transported under the waste manifest by a certified waste transportation company. Once all of these materials have been removed, structure demolition will commence.

A lead based paint survey will be conducted under applicable state and federal. Abatement or paint stabilization techniques will be applied consistent with state and federal law will be applied prior to demolition. Such measures will include removal and stabilization of loose, flaking or peeling paint. Measures will be taken to ensure that paint chips are not generated in the demolition process.

Once peeling paint has been removed and remaining paint surfaces have been stabilized demolition can commence.

Lead paint having concentrations of 0.1% or more will be disposed of as hazardous if the composite samples exceed this level. Composite samples of the demolition waste should be collected and analyzed for lead content by TTLC, then Cal WET, and finally TCLP methods to characterize it for disposal.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-65
All removal and stabilization will be conducted by certified lead abatement contractors. Workers addressing lead paint condition will be subject to monitoring, personal protective equipment and control measures while abatement and demolition is being done to ensure that workers are not being exposed above regulatory Permissible Exposure Limits (PEL).

HAZ-8 Underground Storage Tank Removal
UST will be permanently closed in accordance with the San Bernardino County requirements.

USTs will be purged, cleaned, and excavated. All above and below ground UST appurtenances such as dispensers will be removed and disconnected from vents or other above and below ground piping, including all other underground utili ties associated with the buried UST. Prior to tank removal, preparation activities will be performed by purging and cleaning the USTs. The tanks will then be removed by exposing (excavating) soils over and around the USTs, lifting the USTs from the excavation, sampling the excavation, further excavation as required to meet applicable regulatory thresholds, and backfilling the excavation with clean certified soil.

The USTs and appurtenances will be transported as hazardous waste, accompanied by a California Hazardous Waste Manifest and taken to a licensed Treatment, Storage, and Disposal Facility (TSDF). USTs may only be handled as non -hazardous if they are triple rinsed onsite and the rinsate is manifested and hauled to a licensed TSDF.

Soil samp les will be collected per the San Bernardino County UST removal procedures. A minimum of one (1) sample will be collected from the fill end, and one (1) sample from the turbine end of the UST. Samples will also be collected at least 2 feet below native soil and a separate sample will be collected at each dispenser, and at every 20 linear feet of piping and/or at each joint, bend or connection. Soil samples will be collected from the soil stockpiled from the excavation. Soil samples will be submitted to a St ate of California, Department of Health Services certified Laboratory for chemical analysis of all constituents of the previously stored hazardous substances and their breakdown or transformation products.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-66
that do not contain PCBs. The old t ransformers will be disposed of through a commercially permitted PCB disposal company, as identified by the U.S. Environmental Protection Agency.

HAZ-10 Schools
Any school proposed as part of the redevelopment of the Project site will be subject to the oversight of the California Department of Toxic Substances Control, as required by State law. Any school site will be free of contamination or, if the properties were previously contaminated, they will be cleaned up under DTSC's oversight to a level that protects the students and staff who will occupy the new school.

2022 Amendment Project: Previous hazards identified in connection with former Rialto Airport operations do not affect the 2022 Amendment Project site. As shown at Exhibit

4.7-2, Hazard Property Location Map, of the 2010 Renaissance Specific Plan EIR, the Project site is not located within the identified hazard areas.

The 2022 Amendment Project would not re sult in or cause exposure(s) to hazards or potentially hazardous conditions. That is, uses proposed by the Project are not considered hazardous. Nor does the Project propose or require facilities or operations involving inherent substantial hazards.

During the normal course of construction and operation activities, there would be limited transport of potentially hazardous materials (e.g., gasoline, diesel fuel, paints, solvents, fertilizer, etc.) to and from the site. However, the Project would be required to comply with a Project -specific Hazardous Materials Management Plan, and related regulations addressing transport, use, storage and disposal of these materials. The Project does not propose or require uses or activities that would result in atypical transportation, use, storage, or disposal of hazardous or potentially hazardous materials not addressed under current regulations and policies.

Further, any occupancies that would store or use hazardous materials would be required to comply with California Hazardous Materials Business Plan (HMBP) requirements (California Health & Safety Code, Division 20, Chapter 6.95) The HMBP contains detailed information on the storage of hazardous materials at regulated facilities. The © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-67
purpose of the HMBP is to prevent or minimize damage to public health, safety, and the environment, from a release or threatened release of a hazardous material. The HMBP also provides emergency response personnel with adequate information to help them better prepare and respond to chemical-related incidents at regulated facilities.

The 2022 Amendment Project does not propose or require uses that would handle hazardous or acutely hazardous materials, substances, or waste. Heavy duty truck traffic accessing the site would generate diesel pa rticulate matter (DPM). DPM is a known carcinogen. As substantiated in the Project Air Quality Impact Analysis and Health Risk Assessment (IS/MND Appendix A) DPM emissions generated by the Project would not result in potentially significant hazardous impacts.

Based on the preceding, the potential for the Project to create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials is considered less -than-significant.

Based on the preceding, when compared
to impacts identified in the Certified EIR, the 2022 Amendment Project would not result in new or substantially increased impacts or substantially different impacts related to use, transport, or potential upset of hazardous materials.

2022 Amendment Project Mitigation Measures: None. Certified EIR Mitigation Measures HAZ-1 through HAZ-10, presented previously, are specific to areas that do not encompass the Amendment Project site. Thus, they are not applicable to the Amendment Project.

b) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study concluded that the 2016 RSPA would not create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment. The use of hazardous materials and substances would be minimal, and impacts were considered less-than-significant (Initial Study, p. 41).

Certified EIR Mitigation Measures: None.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-68
2022 Amendment Project: As substantiated at Checklist item 9(a), the 2022 Amendment Project would not result in or cause exposure(s) to hazards or potentially hazardous conditions. Nor does the Project propose or require facilities or operations involving inherent substantial hazards. Therefore, no release of hazardous materials into the environment through reasonably foreseeable upset and accident conditions is anticipated. The potential for the Project to create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment is therefore considered less -than- significant. When compared to impacts identified in the Certified EIR , the 2022 Amendment Project would not result in new or substantially increased impacts or substantially different impacts in this regard.

2022 Amendment Project Mitigation Measures: None.

c) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: According to the Initial Study, no schools are located within one-quarter mile of the Specific Plan area. The closest school site is Locust Elementary School, located one third mile southwest of the Specific Plan area. The 2016 RSPA included a designated planning area for future school development , which would be subject to the oversight of the California Department of Toxic Substances Control, as required by State law. The Initial Study concluded that the 2016 RSPA would have no impact in this regard (Initial Study, p. 41).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: No schools are located within one-quarter mile of the Project site. The school nearest the site is Wilmer Amina Carter High School, located approximately 0.7 mile northeasterly of the site. Further, the 2022 Amendment Project does not propose or require uses or activities that would emit hazardous emissions. Nor does the Project propose or require uses or activities that involve handling of hazardous or acutely hazardous materials, hazardous substances, or hazardous waste. Accordingly, the Project would have no potential to emit hazardous emissions or handle hazardous or © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-69
acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school. When compared to the Certified EIR, t he 2022 Amendment Project would not result in new or substantially increased impacts or substantially different impacts related to potentially hazardous emissions or hazardous materials impacts at vicinity schools.

2022 Amendment Project Mitigation Measures: None.

d) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study determined that the site is not included on a hazardous sites list compiled pursuant to California Government Code Section 65962.5.17; no impact would occur (Initial Study, p. 41).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The Phase I ESA verified that the subject site is not included on a hazardous materials sites list compiled pursuant to Government Code Section 65962.5. When compared to impacts identified in the Certified EIR , the Amendment Project would not result in new or substantially increased impacts or substantially different impacts in this regard.

2022 Amendment Project Mitigation Measures: None.

e) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Rialto Municipal Airport formerly occupied a substantial portion of land within the Specific Plan area. The 2010 Renaissance Specific Plan envisioned that this airport would be closed as development occurs within the area, which occurred in September 2014. The Initial Study concluded that the potential for the 2016 RSPA to result in a safety hazard or excessive noise for people residing or working in the project area was less-than-significant (Initial Study, p. 42).

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-70
Certified EIR Mitigation Measures: None.

2022 Amendment Project: No airports are located within two miles of the Project site.

The airports nearest the site are the San Bernardino International Airport and the Ontario International Airport, both located approximately ten miles away. At this distance, the potential for the 2022 Amendment Project to result in a safety hazard or excessive noise for people residing or working in the P roject area is considered less- than-significant.

Based on the preceding, no new or substantially increased impacts related to airport hazards/airport compatibility would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

f) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study concluded that primary access to all major roads would be maintained during construction, and the 2016 RSPA would not impair or physically interfere with an adopted emergency response or evacuation plan. No impact was identified (Initial Study, p. 42).

Certified EIR Mitigation Measures: None.

2022 Amendment Project : The 2022 Amendment Project does not propose or require permanent alteration of vehicle circulation routes, and would not interfere with any identified emergency response or emergency evacuation plan. Consistent with City policies, coordination with the local fire and police departments during pre-construction review of Project plans would ensure that potential interference with emergency response plans and evacuation plans are avoided. When compared to impacts identified in the Certified EIR, n o new or substantially increased impacts regarding emergency response plans or emergency evacuation plans would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-71
g) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: According to the Initial Study, the 2016 RSPA would not expose people or structures to a risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands. According to the EIR prepared for the 2010 Renaissance Specific Plan, the County General Plan indicates that the area is categorized as having a “low” risk from wildland fires. Impacts related to wildland fires would not be significant (Initial Study, p. 42).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: As shown at Rialto General Plan Exhibit 5.3, Fire Hazards, the Project site is not located within an area classified as a very high fire hazard severity zone.

Fire protection services for the site and vicinity are currently provided by the Rialto Fire Department. Adherence to Fire Department building and site de sign requirements, and compliance with codified fire protection and prevention measures would ensure that the Project would not expose people or structures to a risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands. On this basis, when compared to the Certified EIR findings, no new or substantially increased wildfire impacts would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

Substantiation:

a) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: An approved SWPPP would need to be prepared for the area prior to the issuance of an NPDES permit. The SWPPP would incorporate Best Management Practices ( BMPs) such as sedimentation basins, silt fence, and fiber rolls, which would minimize storm water runoff during construction. Implementation of BMPs during construction would minimize water quality impacts to less-than-significant.

Additionally, as a standard condition of approval, the City of Rialto and the RWQCB would require all projects within the Specific Plan area to prepare and implement a Water Quality Management Plan (WQMP) that would control and reduce polluted urban runoff from the Specific Plan area. The Certified EIR determined that compliance with the City’s standard conditions of approval will reduce the Project’s impacts in this regard to less than significant. (Certified EIR, pp. 4.5-6 – 4.5-7).

Certified EIR Mitigation Measures: None.

2022 Amendment Project : Consistent with City requirements, a WQMP and SWPPP would be prepared for the Amendment Project. City r eview and approv al of these documents is required prior to issuance of Grading Permits . As with the 2016 RSPA , implementation of an approved SWPPP and WQMP would reduce the potential for the Amendment Project to violate water quality standards or otherwise adversely affect water quality to levels that would be less-than-significant.

Based on the preceding, the 2022 Amendment Project’s potential to violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality is considered less -than-significant. When compared to the Certified EIR findings, no new or substantially increased water quality impacts would result from the 2022 Amendment Project.

b) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR did not identify any potential impacts in this regard (Certified EIR, p. 1-22).

Certified EIR Mitigation Measures: None.

2022 Amendment Project : Direct additions to or withdrawals of groundwater are not proposed or required by the 2022 Amendment Project . Construction proposed by the Project would not involve massive substructures at depths that would significantly impair or alter the direction or rate of flow of groundwater. The 2022 Amendment Project does not propose or require uses or facilities that would affect designated groundwater recharge areas.

Based on the preceding, t he 2022 Amendment Project would not contribute to groundwater depletion or interfere with groundwater recharge to an environmentally significant degree. When compared to impacts identified in the Certified EIR, no new or substantially increased groundwater impacts would result fro m the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

c) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: According to the Initial Study prepared for the Certified EIR, the 2016 RSPA Project would not substantially alter the existing drainage patterns of the site or vicinity. The site does not include any streams or rivers. Implementation of mitigation measures identified in the 2010 Renaissance Specific Plan EIR require coordination with the City of Rialto Public Works Department and RWQCB during design and construction to ensure consistency with long range planning efforts. With the implementation of Mitigation Measures HYD-1 through HYD-6, impacts would be less- than-significant (Initial Study, p. 44).

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-75
Certified EIR Mitigation Measures:

HYD-1 Prior to issuance of grading permits, the developers or their designees shall coordinate the design and obtain approval of all flood control and storm drain structures as identified in project hydrology studies. The developers or their designees shall provide evidence of this approval to the City Public Works Department. These improvements shall be consistent with any master planning efforts of the County to the satisfaction of the City Engineer.

HYD-2 The developers or their designees shall obtain a General Permit for StormWater Discharge Associated with Construction Activity (Construction Activity General Permit). The developers or their designees shall prov ide a copy of this permit to the City Public Works Department prior to the issuance of grading permits.

HYD-3 Prior to the issuance of grading permits, the developers or their designees shall prepare a WQMP and an Erosion and Sediment Control Plan (ESCP) to implement the most appropriate BMPs and to prevent any significant removal and/or downstream deposition of soil from the Project area during construction. The WQMP and ESCP shall contain provisions requiring that all erosion control measures and structures be maintained and repaired as needed for the life of the Project.

Prior to the issuance of a grading permit, the Public Works Department shall approve the WQMP and ESCP based on review and input by the RWQCB. At the request of the developer, th e City Public Works Department may accept a Stormwater Pollution Prevention Plan (SWPPP) as a substitute for the ESCP as long as it fulfills the intent of this measure to an equivalent degree. The SWPPP or ESCP shall be prepared to the satisfaction of the City Public Works Department. The WQMP and ESCP or SWPPP shall include, but is not limited to, the following:

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-76
systems shall be incorporated at the base of slopes, when determined appropriate, to transport flows in a controlled, non-erodible channel;
d) Indicate w here flows on the site can be diverted from denuded areas and carried in the natural channels on the site;
e) Construct man-made channels to minimize runoff velocities; f) Disturbed areas shall be vegetated and mulched immediately after final grades have b een established;
g) Sediment traps, basins, or barriers (silt fences, hay bales, etc.) shall be established on the property to prevent the release of “first flush” urban pollutants, including sediment, from developed areas, including the emergency access roads. The design and location of these improvements shall be identified in the plan subject to review and approval by the City; h) Drainage facilities designed to transport flows shall be described and the adequacy of the channel shall be verified by City approval of a detailed drainage analysis; i) An inspection and maintenance program shall be included to ensure that any erosion, which does not occur either on or offsite as a result of the Project, will be corrected through a remediation or restoration program within a time frame specified by the City; j) Confirmed observations by the City of uncontrolled runoff being carried onsite will be grounds for suspension of revocation of any grading or building permit in process, or any discretionary permit subsequently applied for until the problem is resolved to the satisfaction of the City Public Works Department.

HYD-4 Prior to the issuance of grading building permits, graded but undeveloped land shall be maintained in a relatively weed -free condition and/or planted with interim landscaping unless building permits are obtained within 180 days o f completion of grading. This measure shall be implemented to the satisfaction of the Development Services Director.

HYD-5 Prior to the issuance of grading permits, the applicant shall demonstrate that the development’s Erosion Control Plans comply with the Statewide General Construction Permit to the satisfaction of the City Engineer and/or Public Works Director as applicable.

HYD-6 Prior to issuance of the first occupancy permit, the developers or their designees shall provide proof to the Public Works Department that the onsite drainage facilities will be maintained by the County, City, HOA, or equivalent. The developer must demonstrate that these facilities will © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-77
be adequately maintained by an appropriate mechanism or organization, to the satisfaction of the City Public Works Department.

2022 Amendment Project: Existing site drainage patterns would be maintained under the developed 2022 Amendment Project. The Project does not propose or require alteration of the course(s) of any streams or rivers. Potential erosion impacts incurred during construction activities are mitigated below the level of significance through the Project’s mandated compliance with a City -approved SWPPP and compliance with SCAQMD [fugitive dust] Rules that prohibit grading activities and site disturbance during high wind events.

Additionally, a Grading and Drainage Plan must be approved by the Building Official and City Engin eer prior to issuance of grading permits. The 2022 Amendment Project would construct all necessary storm drain improvements and storm drain connections consistent with City requirements. All Project stormwater management systems and improvements would be development-specific and localized to the Project area.

The rate and amount of surface water runoff from the developed Project site would be controlled via the Project stormwater management system and Project WQMP so as to preclude s ubstantial erosion, siltation, flooding, exceedance of stormwater drainage system capacities, or contribution of substantial additional pollutants. All Project stormwater management system improvements and the Project WQMP are subject to review and approval by the City.

The Project site is not located within a designated flood zone and is not subject to substantial flood flows. The Project does not propose uses or facilities that would otherwise impede or redirect flood flows.

Based on the preceding, the Project’s potential to: substantially alter the existing drainage pattern of the site or area in a manner which would result in a substantial erosion or siltation on- or off-site; substantially increase the rate or amount of surface runoff in a manner which would result in flooding on - or offsite; create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or © 2022 Applied Planning, Inc.

provide substantial additional sources of polluted runoff; or impede or redirect flood flows is less -than-significant. Based on the preceding, when compared to impacts identified in the Certified EIR, no new or substantially increased drainage/stormwater conveyance impacts would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: Although no Project-specific mitigation is necessary for the Amendment Project, Certified EIR Mitigation Measures HYD -1 through HYD-6 are carried forward in this Addendum.

d) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: According to the Initial Study prepared for the Certified EIR, the Specific Plan area is located approximately 45 miles inland from the Pacific Ocean with onsite elevations ranging from 1,395 to 1,415 feet AMSL. The Specific Plan area is located approximately 2.5 miles from the Lytle Creek Floodway (at its closest point).

Given the distance from the coast, the potential for the site to be inundate d by a large, catastrophic tsunami is extremely low. Accordingly, no associated flood hazard impacts are anticipated to occur. Additionally, a detention basin would be constructed to alleviate drainage issues. No steep slopes are located in the vicinity; therefore, the risk of mudflow is insignificant. The Initial Study concluded that no impacts would occur in this regard from implementation of the 2016 RSPA (Initial Study, p. 45).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The site is not located within a flood hazard zone. Conditions at the subject site with regard to flood hazard impacts, tsunami hazard impacts, or seiche hazard impacts have not changed since preparation of the Certified EIR – the site remains unaffected by substantial potential flood hazards, tsunami hazards, or seiche hazards. No new or substantially increased flood hazard impacts, tsunami hazard impacts, or seiche hazard impacts would result from the Amendment Project.

b) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: Per the 2016 Recirculated Draft SEIR:

“The proposed [2016 RSPA] Project would not conflict with applicable land use plans, policies, or regulations, including the Southern California Association of Governments’ (SCAG) Regional Transportation Plan (RTP) 2012-2035 Sustainable Communities Strategy (SCS) (adopted April 2012) and the City of Rialto General Plan (updated December 2010). The [2016 RSPA] Project is located within the 2010 Renaissance Specific Plan area, but is not consistent with land use designations and zoning for specific lots as defined within the Specific Plan area. However, the proposed land uses represent some re- distribution of previously -identified land uses in the Renaissance Specific Plan. Since the proposed [2016 RSPA] Project would be consistent with the 2010 Renaissance Spe cific Plan. The land uses are © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-81
generally the same or very similar to what was proposed in the 2010 plan however, the redistribution and relocation of the land uses in intended to provide a more efficient land use concept and to better separate residential and non- residential uses for better land use compatibility. No land use conflicts have been identified. The potential environmental effects of the proposed land use changes are evaluated in the other chapters of this [2016 RSPA] EIR. According to the EIR prepared for the 2010 Renaissance Specific Plan, the Specific Plan area is not located within a habitat conservation plan or natural community’s conservation plan” ( 2016 Recirculated Draft SEIR, p. 6-7).

On the basis of the above, the 2016 Recirculated Draf t SEIR determined that the 2016 RSPA would not result in or cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect.

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The 2022 Amendment Project would amend the 2016 RSPA to allow for development of up to 116,525 square feet of light industrial/warehouse uses within a 5.22-acre site located in the northern portion of the 2016 RSPA. To accommodate the 2022 Amendment Project, the Specific Plan Land Use designation of the site would be changed from “Corporate Center” (CC) to “Business Center” (BC).

The 2022 Amendment Project would be required to comply with applicable General Plan Policies, applicable requirements of the 2016 RSPA (as amended), and provisions of the City Development Code. Collectively, the General Plan Policies, the amended Specific Plan, and the City Development Code act to minimize potential environmental effects that may result from the land uses implemented under the 2022 Amendment Project. On this basis, the potential for the 2022 Amendment Project to conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect is considered less-than-significant.

2022 Amendment Project: Potential noise impacts of the Project are evaluated in Orbis Rialto II, Noise Impact and Vibration Analysis, City of Rialto (Urban Crossroads, Inc.) January 18, 2022 (Project Noise Impact Analysis). Findings and conclusions of the Project Noise Impact and Vibration Analysis are summarized below. As substantiated in the Proj ect Noise Impact Analysis, and summarized below, when compared to findings of the Certified EIR, the 2022 Amendment Project would not result in any new or substantially increased noise impacts.

Overview
The Project proposes conventional light industrial/ warehouse uses within an urban context. Project construction activities would result in temporary and intermittent increases in area noise levels. Project operations would result in permanent increases in area noise levels. Temporary and intermittent Proje ct construction-source noise impacts would be less -than-significant. Long-term operational-source noise impacts would also be less-than-significant. Substantiating discussions are provided below.

Noise Impact Significance Criteria
The significance criteria presented at Table 13-1 were employed in evaluating the Project potential noise/vibration impacts. These significance criteria are based on available City standards. In instances where City standards do not exist, criteria reflect best management practices and standards of relevant state and federal noise impact analysis guidance. Please refer also to Project Noise Impact Analysis Section 4, Significance Criteria.

Project noise levels exceeding the criteria presented at Table 13 -1 would be considered potentially significant impacts.

Construction-Source Noise Impacts
Project construction noise-generating activities would include: site preparation, grading, building construction, architectural coating and paving. Project construction-source noise has the potential to result in a substantial temporary or periodic increase in ambient noise levels. The Project would not otherwise result in sources of potentially substantial temporary or periodic noise.

The Project Noise Impact Analysis substantiates that at potentially affected receivers, the maximum Project construction-source noise levels would range from 35.8 dBA Leq to 45.4 dBA Leq (Project Noise Impact Analysis, p. 56). The received noise levels would not exceed the 80 dBA L eq threshold condition identified at previous Table 13 -1, and would therefore not represent a s ubstantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of applicable standards of other agencies.

Construction-source noise impacts would therefore be less-than-significant.

Operational-Source Noise Impacts
Operational noise sources would include noise generated by on -site activities (stationary/area sources) and noise generated by Project traffic (vehicular sources). As discussed below, Project stationary/area-source noise and Project vehicular-source would © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-91
not result in or cause an increase in ambient noise levels in excess of applicable standards.

Project operational-source noise impacts would therefore be less-than-significant.

Stationary/Area-Source Noise Impacts
Stationary/area-source noise would be generated by loading dock activity, roof -top air conditioning units, parking lot vehicle movements, and other various on -site activities.

The Project Noise Impact Analysis substantiates that at potentially affected rec eivers, Project stationary/area-source noise levels would range from 17.0 to 42.4 dBA L eq during the daytime, with the same received levels during nighttime conditions (Project Noise Impact Analysis, p. 48). As discussed below, the Project Noise Impact An alysis further substantiates that Project stationary/area-source noise when added to ambient conditions would not cause or result in exceedance of applicable thresholds. Per the criteria at previous Table 13-1, depending on the ambient condition, incremental operational/area- source noise contributions of 1 – 5 dBA L
eq would be within acceptable threshold
parameters.

Daytime ambient noise conditions at potentially affected receptors range from 54.0 dBA L
eq to 67.9 dBA Leq (see previous Table 13 -2). The daytime ambient condition at certain potentially affected receptors therefore already exceed the City daytime standard of 55 dBA Leq. With the addition of Project noise, the daytime noise levels would range from

54.3 dBA Leq to 67.9 dBA L eq. Under daytime conditions, incremental Project stationary/area-source noise contributions would not exceed the applicable incremental thresholds of 1 – 5 dBA L eq (Project Noise Impact Analysis, p. 50). Under daytime conditions, Project operational-source noise would therefore not represent a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of applicable standards of other agencies. Impacts would therefore be less- than- significant.

Nighttime ambient noise conditions at potentially affected receptors range from 53.9 dBA Leq to 66.4 dBA Leq (see previous Table 13-2). The nighttime ambient condition at certain potentially affected receivers therefore already exceeds the City 45 dBA L eq nighttime exterior noise standard. With the addition of Project noise, the nighttime noise levels would range from 54.2 dBA Leq to 66.4 dBA Leq. Under nighttime conditions, incremental © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-92
Project stationary/area -source noise contributions would not exceed the applicable incremental thresholds of 1 – 5 dBA L eq (Project Noise Impact Analysis, p. 50). Under nighttime conditions, Project operational -source noise would therefore not represent a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of applicable standards of other agencies. Impacts would therefore be less-than-significant.

Vehicular-Source Noise Impacts
The Project Noise Impact Analysis evaluated vehicular -source impacts under the following scenarios:

• Existing Without / With Project;
• Existing plus Ambient (EA) Without / With Project; and • Existing plus Ambient plus Cumulative (EAC) Without / With Project.

Traffic volumes employed in the vehicular -source noise impact analysis were obtained from Orbis Rialto II, Traffic Analysis , City of Rialto (Urban Crossroads, Inc.) January 10, 2022.

Per the criteria at Table 13-1, depending on the ambient condition, incremental vehicular- source noise contributions of 1 – 5.0 dBA CNEL would be within acceptable threshold parameters. As summarized below, the Project Noise Impact Analysis substantiates t hat under all scenarios, at potentially affected receptors, Project vehicular -source noise contributions would not exceed the applicable incremental thresholds of 1.0 – 5.0 dBA CNEL. Vehicular-source noise impacts would therefore be less-than-significant.

Existing Conditions with Project Scenario
Under the Existing Condition s with Project Scenario, Amendment Project traffic would generate a noise level increase of up to 0.6 dBA CNEL on the Study Area roadway segments. Project vehicular-source noise contributions would not result in unacceptable incremental increases in exterior noise conditions (Project Noise Impact Analysis, p. 36).

Project vehicular-source noise contributions under the “Existing Conditions with Project Scenario” would therefore be less-than-significant.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-93
Existing plus Ambient (EA) with Project Scenario
Under the Existing plus Ambient (EA) with Project Scenario, Amendment Project traffic would generate a noise level increase of up to 0.6 dBA CNEL on the Study Area roadway segments. Project vehicular-source noise contributions would not result in unacceptable incremental increases in exterior noise conditions (Project Noise Impact Analysis, pp. 36, 37). Project vehicular-source noise contributions “Under the Existing plus Ambient (EA) with Project Scenario,” would therefore be less-than-significant.

Existing plus Ambient plus Cumulative (EAC) with Project Scenario Under the Existing plus Ambient plus Cumulative (EAC) with Project Scenario, Amendment Project traffic would generate a noise level increase of up to 0.6 dBA CNEL on the Study Area roadway segments. Project vehicular -source noise contributions would not result in unacceptable incremental increases in exterior noise conditions (Project Noise Impact Analysis, pp. 36, 37). Proj ect vehicular-source noise contributions under the “Existing plus Ambient plus Cumulative (EAC) with Project Scenario” would therefore be less-than-significant.

As substantiated in the preceding discussion under all conditions and development scenarios, the potential for the Amendment Project to generate substantial temporary or permanent increases in excess of standards established in the local general plan or no ise ordinance, or applicable standards of other agencies would be less-than-significant.

Based on the preceding, when compared to impacts identified in the Certified EIR, no new or substantially increased environmental impacts would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

b) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR evaluated all potential construction -source and operational-source vibration impacts that would result from the 2016 RSPA. The 2016 © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-94
Recirculated Draft SEIR concluded that potential vibration impacts resulting from the 2016 RSPA would be less-than-significant (Certified EIR, pp. 4.6-18 – 4.6-22).

Certified EIR Mitigation Measures: Although no Project-specific mitigation is necessary for the Amendment Project, certain Certified EIR Noise Mitigation Measures are carried forward in this Addendum. Please refer to Table 5.1-1.

2022 Amendment Project: Project construction activities could result in exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels.

The Project would not otherwise be a source of vibration.

The Project Noise Impact Analysis noise analysis substantiates that at potentially affected receivers, the maximum received construction -source vibration levels would effectively be 0.000 Peak Particle Velocity (PPV, inches/second) (Project Noise Impact Analysi s, p. 58). The received vibration levels would not exceed the 0.03 PPV significance threshold identified at Table 13-1. Vibration impacts would therefore be less-than-significant.

Based on the preceding, when compared to impacts identified in the Certified EIR, no new or substantially increased environmental impacts would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

c) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study concluded that implementation of the 2016 RSPA would not result in any impacts related to effects of or contributions to airport/airfield noise (Initial Study, p. 51).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The Project would be implemented within the boundaries of the 2016 SPA site. Conditions related to airports, airfields and associated noise have not changed © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-95
since preparation of the Certified EIR. That is, there are no airport/airfield noise sources that would potentially affect the Project nor would the Project contribute to or result in adverse airport/airfield noise impacts. The Project would therefore not be exposed to excessive airport/airfield-source noise levels. The Project would not otherwise be exposed to potentially adverse airport/airfield-source noise levels, nor does the Project propose or require uses that would contribute to or exacerbate airport-source noise impacts.

Based on the preceding, the Project would not be adversely affected by airport/airfield noise, nor would the Project contribute to or result in adverse airport/airfield noise impacts. When compared to the Certified EIR findings, no new or substantially increased impacts would result from the Project.

14. POPULATION AND HOUSING
Would the project:

b) Displace substantial numbers of
existing people or housing,
necessitating the construction of
replacement housing elsewhere?

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-96
Substantiation:

a, b) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: No potentially significant impacts to population and housing were identified in the 2010 Renaissance Specific Plan EIR. Residential land uses proposed by the 2016 RSPA would not exceed residential land uses as planned by the 2010 Renaissance S pecific Plan EIR . No population and housing impacts were identified (Initial Study, p. 52).

Certified EIR Mitigation Measures: None.

2022 Amendment Project:

Direct Population Growth Inducement

The 2022 Amendment Project does not propose new residential development and would not directly contribute to population growth within the City. Project-related employment demands would likely be filled by the existing personnel pool within the City and neighboring communities, with little or no measurable increase in the City resident population. Significant population growth is therefore not anticipated to occur as a direct result of Project implementation.

Indirect Growth Inducement
The 2022 Amendment Project is located within an urbanized area that is already served by roadways, utilities, and other infrastructure. The Project does not propose or require infrastructure improvements that would encourage or facilitate unanticipated population growth.

Based on the preceding, the potential for the 2022 Amendment Project to induce substantial growth directly or indirectly is considered less-than-significant.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-97
Consistency with Population Growth Projections
SCAG population growth projections reflect assumptions and development scenarios incorporated in local plans including City general plans. As demonstrated in the preceding discussions, the 2022 Amendment Project would not induce or generate growth beyond that reflected in the General Plan and evaluated in the Certified EIR.

Accordingly, the 2022 Amendment Project would not result in growth not already anticipated within SCAG population growth projections for the region.

Housing Considerations
No housing exists within the Project site, and the 2022 Amendment P roject does not propose uses or activities that would otherwise displace housing assets or persons. Based on the preceding, the 2022 Amendment Project would have no impacts related to displacement of housing or displacement of people.

As supported by the preceding discussion s, the 2022 Amendment Project would not induce substantial population growth; displace substantial numbers of existing housing; or displace substantial numbers of people. When compared to the Certified EIR findings, no new or substanti ally increased impacts would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

Would the project result in substantial
adverse physical impacts associated

construction of which could cause
significant environmental impacts, in
order to maintain acceptable service
ratios, response times or other
performance objectives for any public

Substantiation:

a – e) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: As discussed in the 2016 Recirculated Draft SEIR:

“Police and fire protection for the proposed Project would be handled by those agencies already providing these services to the immediate vicinity.

As a means to provide adequate funding for fire protection, police, and other essential public services, the city has established development impact fees that are charged to all new development within Rialto. Therefore, implementation of the proposed Project, with payment of the required development impact fees, would result in a less than significant impact on emergency services, fire protection, and police protection. Implementation of a Traffic Control Plan, as determined necessary by the City of Rialto, would reduce the potential for short term impacts to emergency services, fire, and police protection to occur. Furthermore, no potentially significant impacts to schools, parks or other public facilities, are identified in the 2010 Renaissance Specific Plan EIR (2016 Recirculated Draft SEIR, p. 6-8). © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-99

In addition, there are fewer residences proposed with the RSPA than identified in the 2010 Renaissance Specific Plan EIR and therefore, fewer students will be generated with the project. Future development within Renaissance Specific Plan will pay development impact fees as established by applicable school district at the time building permits are issued. The proposed project provides for a future K -8 school within the RSPA area.

Future high school students would attend existing high schools within the Rialto Unified School District or the Fontana Unified School District” (Certified EIR, p. 6-8).

Based on the preceding, the Certified EIR concluded that the potential for the 2016 RSPA to result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, ( including fire protection f acilities, p olice protection facilities, school facilities, park facilities, or other public faci lities) would be less-than-significant.

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The 2022 Amendment Project would be constructed within an already-developed urban environment. Fire protection and police protection services are currently available to the subject site via existing facilities. Further , the light industrial/warehouse uses proposed by the 2022 Amend ment Project would not create substantive additional demands for school or park facilities. Development impact fees and sales tax revenues generated by the 2022 Amendment Project would provide funding sources available for support and enhancement of public services commensurate with incremental demands of the development. By law, the 2022 Amendment Project would be required to remit school impact fees . On this basis, the potential for the 2022 Amendment Project to result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, (including fire protection facilities, p olice protection facilities , s chool facilities , p ark facilities , or other public facilities) would be less-than-significant.

16. RECREATION
Would the project:

X
b) Include recreational facilities or require
the construction or expansion of
recreational facilities which might have
an adverse physical effect on the
environment?

Substantiation:

a, b) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study determined that, because land uses proposed by the 2016 RSPA were consistent with the Specific Plan, no recreational impacts would occur (Initial Study, p. 55).

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-101
2022 Amendment Project: The 2022 Amendment Project would not affect or alter parks and other recreational facilities approved under the Original Project. The Project would not implement additional residential uses that would substantially increase demands on recreation facil ities. Proposed light industrial uses implem ented under the 2022 Amendment Project would no t generate additional resident populations that would substantially increase demands on recreational facilities. The potential for the Project to increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated; or to include or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment is therefore considered less-than-significant. When compared to the Certified EIR findings, n o new or substantially increased recreation impacts would result from the 2022 Amendment Project.

Substantiation: Transportation impact analyses prepared the 2022 Amendment Project presented below are summarized in part from Orbis Rialto II, Traffic Analysis, City of Rialto (Urban Crossroads, Inc.) January 10, 2022 (Project Traffic Analysis). The Project Traffic Analysis is presented at Addendum Appendix H.

a) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: Certified EIR Section 4.7, Traffic and Transportation, concluded that with implementation of mitigation (see Certified EIR Mitigation Measures , following) the potential for the 2016 RSPA to conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities would be less-than-significant (Certified EIR, pp. 4.7-13 – 4.7-50).

It is noted here that the Certified EIR analysis reflected the then applicable analytic discussions and related mitigation measures addressing projected Level of Service (LOS) impacts resulting from implementation of the 2016 RSPA. The City specifically recognizes that vehicle delay (Level of Service, LOS) deficiencies are no longer environmental impacts under CEQA.
2 2 CEQA Guidelines Section 15064.3, effective January 1, 2019, “describes specific considerations for evaluating a project’s transportation impacts” and provides that, except for roadway capacity projects, “a project’s effect on automobile delay (or LOS) shall not constitute a significant environmental impact.” (CEQA Guidelines, § 15064.3, subd. (a).) © 2022 Applied Planning, Inc.

Certified EIR Mitigation Measures:

TRANS-1 Prior to the issuance of building permits, the City Traffic Engineer shall review individual site -specific development proposals to evaluate whether such proposals would cause LOS failure at project intersections. If it is determined that traffic generated from such proposal would cause LOS failure, the applicant shall provide, either through construction of and/or monetary contribution for, improvements listed in Table 4.7-20, Table 4.7-21, and Table 4-7-22 of the Recirculated Draft SEIR. Such improvements and/or monetary contribution shall be provided in proportion to an individual project’s impacts on traffic and to the satisfaction of the City Traffic Engineer.

TRANS-2 Prior to issuance of building permits, the Renaissance Marketplace project applicant shall enter into a Development Agreement (DA) with the City of Rialto. This DA shall describe the timing and implementation of project -specific improvements, as wel l as existing funding mechanisms and proportional fair -share contributions, for the improvements listed in Table 4.7 - 23, Table 4.7-24, Table 4.7-25, and Table 4.7-26 of the Recirculated Draft SEIR. Where no existing funding mechanism exists for recommended improvements, the DA shall stipulate that the applicant shall pay not less than the fair share contribution to mitigate project impacts.

TRANS-3 Prior to issuance of building permits, the Planning Area 108 (PA 108) applicant shall enter into a Developmen t Agreement (DA) with the City of Rialto. This DA shall describe the timing and implementation of project -specific improvements, as well as existing funding mechanisms and proportional fair-share contributions, for the improvements listed in Table 4.7.27, Table 4.7-28, Table 4.7-29, and Table 4.7 -30 of the Recirculated Draft SEIR. Where no existing funding mechanism exists for recommended improvements, the DA shall stipulate that the applicant shall pay not less than the fair share contribution to mitigate project impacts.

2022 Amendment Project : The 2022 Amendment Project does not propose elements or aspects that would conflict with adopted alternative transportation policies. Bus service is © 2022 Applied Planning, Inc.

available to the City via Omnitrans. No bus routes currently provide proximate service (within one-quarter mile) of the Project site. Transit service providers periodically review and update schedules and routes to address ridership, budget, and community demands.

The Applicant and City would coordinate Project final designs with Omnitrans to evaluate the potential for provision of bus services and bus amenities serving the Project site. Omnitrans bus routes and schedules can be accessed at: https://omnitrans.org/plan- a-trip/routes-schedules/.

As part of the 2022 Amendment Project roadway/access improvements, the sidewalks would be constructed along the site’s West Renaissance Parkway and North Locust Avenue frontages. Additionally, the 2022 Amendment Project would provide bicycle parking and bicycle amenities consistent with City requirements. The 2022 Amendment Project does not propose or require facilities or operations that would conflict with or obstruct City pedestrian access or bicycle access plans or programs.

All 2022 Amen dment Project circulation system improvements including roadways, sidewalks, and bike lane/route improvements would be designed and constructed consistent with City standards.

Pedestrian access would be provided within the 2022 Amendment Project site wit h connections to existing and future walkways along adjacent roadways. The 2022 Amendment Project would facilitate and would not obstruct City goals and policies to provide efficient and safe pedestrian access.

Consistent with City requirements, the 2022 Amendment Project would pay Development Impact Fees (DIF) providing for improvement of the area circulation system, acting to offset incremental effects of traffic. The 2022 Amendment Project is also subject to, and would be require d to comply with, any outstanding DA provisions entered into as part the 2016 RSPA approval process.

Based on the preceding, the potential for the 2022 Amendment Project to conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities is considered less-than- © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-105
significant. When compared to the Certified EIR findings, no new or substantially increased impacts would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: Although no Project-specific mitigation is necessary for the Amendment Project, Certified EIR Mitigation Measure TRANS -1 is carried forward in this Addendum. Measures TRANS -2 and TRANS -3 are specific to properties that do not affect the Addendum Project site, and as such, are not applicable.

Note: As required by the City, and in support of the 2022 Amendment Project generally, an LOS analysis is included as part of the Project Traffic Analysis . Outside of a CEQA analysis context, the City may require implementation of improvements identified in the Project Traffic Analysis intended to improve or maintain area LOS conditions.

b) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: CEQA Guidelines Section 15064.3, subdivision (b) was added to the CEQA Guidelines in 2019. The Vehicle Miles Traveled (VMT) metric established under Section 15064.3 is recognized. The VMT metric became effective a July 2020. VMT impacts were not evaluated under the Certified EIR.

As of the date of the preparation of this Addendum, the City has not yet formally adopted its own VMT analysis protocols or adopted VMT impact significance thresholds. Pending adoption of City VMT analysis protocols and VMT impact significance thresholds, and consistent with City guidance, San Bernardino County Transportation Impact Study Guidelines, July 2019 (County Guidelines) addressing VMT impact considerations have been employed in this analysis.

Certified EIR Mitigation Measures: Not Applicable.

Project Screening
Consistent with criteria established under the County Guidelines , projects that meet certain screening thresholds based on their location and project type may be presumed to result in a less -than-significant VMT impact. Consistent with the County Guideline s screening criteria, the following project-level VMT screening criteria have been employed in this analysis:

• Project Type Screening;
• Transit Priority Area (TPA) Screening;
• Low VMT Area Screening.

A land use project need qualify under only one of the above screening criteria to result in a less-than-significant impact. Development proposals that do not qualify under one the above-listed screening criteria are required to prepare a project -level VMT analysis. The Project considered herein qualifies under the “Project Type” screening criteria.

Specifically, the Project Type screening criteria provides that new development that generates fewer than 110 daily vehicle trips would result in a less -than-significant VMT impact. The Project Traffic Analysis substantiates the following:

• Development of subject the site as approved under the 2016 RSPA and evaluated in the Certified EIR generated approximately 780 daily trips, with 117 trips in the morning peak hour, and 101 trips in the evening peak hour.

• The 2022 Amendment Project would generate 704 tri ps daily, with 63 trips in the morning peak hour, and 67 trips in the evening peak hour (Project Traffic Analysis, Table 4-2).

• Compared to development of subject the site as approved under the 2016 RSPA and evaluated in the Certified EIR, the 2022 Amendm ent Project would generate 76 fewer daily vehicle trip ends, with 54 fewer trips in the morning peak hour and 34 fewer trips in the evening peak hour.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-107
As summarized above, t he 2022 Amendment Project would result in a net reduction of 76 vehicle trip-ends per day, and would therefore not exceed the Project Type screening threshold of 110 daily vehicle trips. VMT impacts of the 2022 Amendment Project are therefore considered less -than-significant; and the potential fo r the 2022 Amendment Project to conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b) is also less-than-significant. Further VMT analysis is not required based on the County Guidance. When compared to the Certified EIR findings, no new or substantially increased impacts would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

c) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Certified EIR concluded that development of the 2016 RSPA would result in changes to the circulation network. However, roadway and intersection designs under the RSPA Project would be required to meet City roadway design criteria requirements through review by the Rialto Department of Public Works, as well as the County of San Bernardino Transportation Commission. Additionally, area- wide improvements implemented under the Certified EIR mitigation measures would further minimize the potential for creation of design hazards or access restrictions or obstructions. On this basis, the Certified EIR concluded that the potential for the 2016 RSPA to substantially increase hazards due to a geometric design feature would be less - than-significant (Certified EIR, pp. 4.7-13 – 4.7-20).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: The 2022 Amendment Project does not propose elements or aspects that would substantially increase transportation/traffic hazards. Moreover, all improvements under the 2022 Amendment Project would be designed and implemented consistent with recommendations of the Project Traffic Analysis, City traffic engineering and safety standards, and 2022 Amendment Project Conditions of Approval, thereby minimizing the potential to result in or cause hazardous traffic/transportation conditions.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-108
The 2022 Amendment Project would generate urban traffic comparable to and compatible with the vehicle mix and vehicle categories present within the area roadway system. The 2022 Amendment Project uses would therefore not cause or result in incompatible vehicle movements or traffic that would substantively increase hazards. Further, based on the projected net decrease in trip generation under the 2022 Amendment Project, th e potential for the 2022 Amendment Project to result in potential traffic hazards would likely be reduced when compared to the uses entitled under the 2016 RSPA and assumed within the Certified EIR. When compared to the Certified EIR findings, no new or substantially increased impacts would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

d) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: The Initial Study concluded that the 2016 RSPA would have no impacts with regard to inadequate emergency access. The issue was not discussed further within the Certified EIR (Initial Study, p. 57).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: Pursuant to the Project Construction Traffic Management Plan (please refer to Addendum Section 2.0, Project Description , 2.5.9 Construction Area Traffic Management Plan ), the 2022 Amendment Project would be required to maintain appropriate access during construction activities. When compared to the Certified EIR findings, no new or substantially increased design hazards or emergency access impacts would occur under the 2022 Amendment Project. Please refer also to the discussion presented above at Checklist Item 17. c).

18. TRIBAL CULTURAL RESOURCES
Would the project cause a substantial
adverse change in the significance of a
tribal cultural resource, defined in Public
Resources Code section 21074 as either a
site, feature, place, cultural landscape that
is geographically defined in terms of the
size and scope of the landscape, sacred
place, or object with cultural value to a
California Native American tribe, and
that is:

X
b) A resource determined by the lead
agency, in its discretion and
supported by substantial evidence, to
be significant pursuant to criteria set
forth in subdivision (c) of Public
Resources Code Section 5024.1. In
applying the criteria set forth in
subdivision (c) of Public Resource
Code Section 5024.1, the lead agency
shall consider the significance of the
resource to a California Native
American tribe.

Substantiation:

a, b) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: This environmental topical concern has recently been added to the CEQA Guidelines Appendix G, Environmental Checklist Form and was therefore not specifically addressed in the Certified EIR. Impacts to historical, archaeological and paleontological resources generally are addressed at Initial Study Section 5, Cultural © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-110
Resources. The Initial Study concluded that impacts to cultural resources would be less- than-significant (Initial Study, p. 32).

Certified EIR Mitigation Measures: Not Applicable.
2022 Amendment Project: Evaluation of impacts to tribal cultural resources pursuant to AB 52, Gatto. Native Americans: California Environmental Quality Act applies only to CEQA projects that are required to file a Notice of Preparation for an Environmental Impact Report, or Notice of Intent to Adopt a Negative Declaration or Mitigated Negative Declaration. Because the 2022 Amendment Project would not be required to file any of the mentioned documents, AB 52 requirements addressing potential impacts to tribal resources are not applicable within the context of this Addendum analysis. It is noted that Mitigation Measures 5 -1 and 7- 1, presented previously, act to preclude impacts to cultural and paleontological resources, including those of Native American origin.

Certified EIR Conclusions: As discussed in the Certified EIR:

“Potential effects are evaluated relative to the construction of new storm water drainage facilities or expansion of existing facilities and the availability of water supplies to serve the Project from existing entitlements and resources, or are new or exp anded entitlements. All other significance thresholds and potential impacts of the proposed Project were addressed in the proposed Project’s NOP (January 2015), which determined there would be no new or additional impacts, or that impacts would be less tha n significant and therefore need not be further considered in this Recirculated © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-112
Draft SEIR. Please refer to the proposed Project’s NOP attached as Appendix A” (Certified EIR, p. 4.8-1).

Potential storm water management and water supply impacts of the 201 6 RSPA were evaluated in Certified EIR and were determined to be less-than-significant (Certified EIR, pp. 4.8-7 – 4.8-11).

Certified EIR Mitigation Measures: None.

2022 Amendment Project:

Infrastructure Systems
Necessary infrastructure systems are locally available to the 2022 Amendment Project.

The 2022 Amendment Project does no t propose or require construction of major infrastructure systems that could result in potentially significant environmental impacts.

All proposed connections to and any necessary modification of serving infrastructure systems would conform to provisions of the 202 2 Specific Plan Amendment , City, and purveyor requirements. On this basis, t he potential for the 2022 Amendment Project to result in significant environmental impacts attributable to the construction or relocation of serving infrastructure systems would be less-than-significant.

Water Supply
As discussed in the Certified EIR:

“At build-out, the RSP is projected to have an annual water demand of 3,807 AFA. Between the three water companies that currently serve the Project area, adequate supply is available to serve the RSP area during multiple drought years (2008 and 2015 update). Furthermore, the WSA has confirmed the City of Rialto and Fontana Water District would have adequate supply available to serve the Project area.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-113
improvements on the existing water supply infrastructure are required in addition to any associated fees and thus the Project- related impacts to the environment through the construction or expansion of existing facilities would be less-than- significant” (Certified EIR, p. 4.8-10).

Although the 2022 Amendment Project would amend the Specific Plan zoning designation for the subject site, the 2022 Amendment Project does not propose or require amendment of the City General Plan. Water demands of the City pursuant to buildout of the City General Plan are reflected in the 2020 Integrated Regional Urban Water Management Plan, Part 2: Local Agency UWMPs, Chapter 5 Rialto 2020 UWMP (Rialto 2020 UWMP). As discussed in the Rialto 2020 UWMP, ther e would be adequate reliable water supplies available to the City under all future scenarios, this would include water available to the Project (Rialto 2020 UWMP, pp. 5- 22 – 5.26). Moreover, the Applicant would be required to obtain a water “Will- Serve” letter from the water purveyor, and would be required to provide such documentation to the City prior to issuance of a Building Permit for the 2022 Amendment Project. On this basis, the potential for the 2022 Amendment Project to have insufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years would be less-than-significant.

Water Treatment/Wastewater Treatment
No additional or non -standard treatment is required to meet the 2022 Amendment Project’s water demands or wastewater treatment demands. The 2022 Amendment Project would be required to pay applicable water and sewer connection and service fees, which act to fund water/wastewater system improvement plans, operations, and maintenance – and offset effects of area development. On this basis, the 2022 Amendment Project would not result in potentially adverse impacts to water treatment or wastewater treatment systems. Based on the preceding, the 2022 Amendment Project would not in impacts that would be substantially different than or greater than impacts considere d and addressed in the Certified EIR.

2022 Amendment Project Mitigation Measures: None.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-114
d, e) No Changes or New Information Requiring Preparation of an MND or EIR.

Certified EIR Conclusions: As noted previously, the Certified EIR concluded that development of the 2016 RSPA would not result in potentially significant solid waste management impacts (Certified EIR, p. 4.8-1).

Certified EIR Mitigation Measures: None.

2022 Amendment Project: Solid waste management demands of the 2022 Amendment Project would be comparable to those of the 2016 RSPA. Moreover, the 2022 Amendment Project would be required to comply with applicable so lid waste management and reduction statutes and regulations , acting to further reduce solid waste management impacts of the 2022 Amendment Project. On this basis, the 2022 Amendment Project would not result in impacts that would be substantially different than or greater than impacts considered and addressed in the Certified EIR.

2022 Amendment Project Mitigation Measures: None.

X
d) Expose people or structures to
significant risks, including downslope

Substantiation:

a – d) No Impact.

Certified EIR Conclusions: This environmental topical concern has been recently added to the CEQA Guidelines Appendix G, Environmental Checklist Form and was therefore not specifically addressed in the Certified EIR.

Certified EIR Mitigation Measures: Not Applicable.

2022 Amendment Project: As shown at General Plan Exhibit 5.3, Fire Hazards, the Project site is not located within or near a state responsibility area, or within an area classified as a very high fire hazard severity zone.

Renaissance Specific Plan, 2022 Amendment Environmental Checklist 2022 Addendum to the 2016 Final EIR Page 3-116
compliance with codified fire protection and prevention measures during construction and operation of the 2022 Amendment Project are required. On this ba sis, when compared to the Certified EIR findings , no new or substantially increased wildfire impacts would result from the 2022 Amendment Project.

2022 Amendment Project Mitigation Measures: None.

This Addendum defines, describes, compares, and contrasts potential environmental impacts of the 2022 Amendment Project in the context of the environmental impacts assessed in the Certified EIR. In so doing, this Addendum substantiates consistency with applicable CEQA Guidelines provisions addressing preparation of an Addendum to a previously-Certified EIR.

As supported by the discussions presented herein , the 2022 Amendment Project would not result in or cause any new significant impacts, substantively increased impacts, or substantively different environmental impacts than those previously considered and addressed in the Certified EIR. Analysis beyond that presented in this Addendum is not required or warranted.

4.0 DETERMINATION
Renaissance Specific Plan, 2022 Amendment Determination 2022 Addendum to the 2016 Final EIR Page 4-1

4.0 DETERMINATION

As supported by the analysis presented herein , the potential environmental effects of the development allowed by the 2022 Amendment Project, and associate d required discretionary actions, have been adequately addressed in the Certified EIR . As such, the development of any f urther information and analysis is not warranted. Pursuant to the requirements of CEQA Guidelines Section 15162 and 15164, the following determinations have been made.

Major Revisions to the Certified EIR Not Required
Based on the preceding analysis and information, there is no evidence that major changes to the Certified EIR are required. This Addendum indicates that there is no new significant or more severe environmental impact, and that the development of the Amendment Project described herein would essentially have the same , or reduced, impacts as those considered and addressed in the Certified EIR.

No Substantial Change in Circumstances Requiring Major Revisions to the Certified EIR No information exists in the record , or is otherwise available that indicates that there are substantial changes in circumstances that would require major changes to the Certified EIR.

No New Information Showing Greater Significant Effects than Identified in the Certified EIR
This Addendum has considered all available relevant information to determine whether there is new information, which was not av ailable at the time the Certified EIR was prepared, that may indicate that a new significant effect may occur that was not reported in the Certified EIR . As supported by the analysis presented in this © 2022 Applied Planning, Inc.

Renaissance Specific Plan, 2022 Amendment Determination 2022 Addendum to the 2016 Final EIR Page 4-2
Addendum, there is no substantial new information that was not available at the time of the Certified EIR , indicating that there would be a new, significant impact requiring major revisions of the Certified EIR.

No New Information Showing Ability to Reduc e Significant Effects Identified in the Certified EIR
The Addendum analysis substantiates that there are no significant impacts requiring identification of alternatives to the Amendment Project. The continued implementation of applicable mitigation from previous relevant CEQA documents as incorporated in this Addendum reduce the Amendment Project’s potentially significant impacts to levels that are less-than-significant.

Summary
The analysis presented in this document substantiates that the analysis presented in the Certified EIR is sufficient to satisfy CEQA requirements for the proposed 2022 Amendment Project. That is, with incorporation of mitigation, implementation of the Amendment Project described and evaluated herein w ould not result in any significant new, different, additional, or substantially increased environmental impacts than were previously considered and addressed in the Certified EIR . As such, environmental assessment of the Am endment Project does not require any major revision of the previously-approved Certified EIR , nor would development allowed by the Amendment Project result in conditions that would require preparation of further analysis as described in the CEQA Guidelines.

techniques can reduce the fugitive dust generation (and thus the PM10 component). Compliance with these rules would reduce impacts on nearby sensitive receptors (see SCAQMD Rule 403).

This applicable Rule measures as follows:
• Apply nontoxic chemical soil stabilizers according to manufacturers’ specifications to all inactive construction areas (previously graded areas inactive for 10 days or more). • Water active sites at least twice daily. (Locations where grading is to occur will be thoroughly watered prior to earthmoving.) • Cover all trucks hauling dirt, sand, soil, or other loose materials, or maintain at least 0.6 meters (2 ft) of freeboard (vertical space between the top of the load and top of the trailer) in accordance with the requirements of California Vehicle Code (CVC) Secti on 23114.
• Pave construction access roads at least 100 ft (30 m) onto the site • from the main road.
• Reduce traffic speeds on all unpaved roads to 15 mph or less.

The applicable California Department of Resources Recycling and Recovery (CalRecycle) Sustainable (Green) Building Program Measures are:
• Recycle/reuse at least 50 percent of the construction material including, but not limited to, soil, mulch, vegetation, concrete, lumber, metal, and cardboard.
• Use “green building materials” such as those material s that are rapidly renewable or resource- efficient, and recycled and manufactured in an environmentally friendly way, for at least 10 percent of the project.

BIO-6 Migratory Birds
Prior to the issuance of grading permits and/or an action that would result in project site disturbance (whichever occurs first) (including but not limited to discing and demolition activities), the project applicant shall submit to the satisfaction of the Development Services Director/Planning Division, evidence that a pre -construction nesting bird survey has been conducted prior to any ground di sturbing activities and removal of vegetation or other potential nesting habitat during the nesting period (generally February 1st to August 31st). If birds are found to be nesting inside or within 250 feet (500 feet for raptors) of the impact area, construction will need to be postponed, at the discretion of a qualified biologist, until it is determined that the nests are no longer active.

Not Applicable. This measure has been replaced by Mitigation Measure 4-1.
4-1 Impacts to nesting birds can be avoided and, compliance with the federal Migratory Bird Treaty Act of 1918 (MBTA) can be accomplished by the following:
• If possible, all vegetation removal activities shall be scheduled from August 1 to February 15, which is outside the nesting season.

This would ensure that no active nests would be disturbed and that removal could proceed rapidly.
• If vegetation is to be cleared during the nesting season (February 15 to July 31), all suitable habitat will be thoroughly surveyed for the presence of nesting birds by a qualified biologist 72 hours prior to clearing. If any active nests are detected, the area shall be flagged and mapped on the construction plans along with a minimum 50-foot buffer and up to 300 feet for raptors, with the final buffer distanc e to be determined by the qualified biologist.

Cultural Resources
CR-4 Monitoring of development -related excavation is required during all construction -related ground disturbances that take place along Baseline Road, Alder Avenue, Laurel Avenue, Locust Avenue, Linden Avenue and Maple Avenue in the southern portion of the project area. Specifically, monitoring is recommended for the entire southern portion of the project area, from Baseline Road to a northern point marked by an east -west extension of Walnut Avenue. This is due to the high level of historic development in the southern portion of the project area, and the resultant high probability that significant, intact subsurface deposits would be found. These monitoring procedures shall be directed by the project archaeologist and discussed with the general contractor onsite before construction begins. Construction- related disturbances in the southern portion of the project area should be monitored on a full-time basis by a qualified cultural resource professional or the project archaeologist. Once 50 percent of the earth to b e moved during grading has been examined, the project archaeologist may, at his or her discretion, terminate monitoring if and only if no buried cultural resources have been detected. If buried cultural resource sites are detected during monitoring, no mat ter whether such resources are significant or not, monitoring must continue until 100 percent of the earth within the southern portion of the project has been disturbed and inspected by the monitor(s). If sites are exposed during construction, they should be handled in the City of Rialto -Renaissance Specific Plan manner established in Mitigation Measures 5 -1 through 5 -3. This Not Applicable. The area specified within Certified EIR Mitigation Measure CR-4 does not encompass the Amendment Project site.

Additionally, t he records search data and field survey conducted as part of the Project -specific Cultural Resources Assessment did not yield any cultural resources within the Amendment Project site boundaries. Conditions have failed to indicate sensitivity for buried cultural resources. As such, the Assessment concludes that no additional cultural resource work or monitoring is necessary for any earthmoving proposed within the site. However, should such resources be discovered during construction, a qualified archaeologist should be contacted to assess the find, as required by new Mitigation Measure 5-1, below.

HAZ-1(a) Excavation and Stockpiling Management
The excavated materials will be segregated based upon type (e.g. tarmac, pavement, and soil) and will be temporarily stockpiled onsite for loading, transport and disposal to an offsite facility, or onsite management, as provided under the Cleanup Plan. Soil excavated will be placed in separate stockpiles based on the COC present in soil. For instance, soil containing PAHs shall be placed in a separat e stockpile from soil containing TRPH and PCBs. The exception to this procedure will be in the case when soil excavated contains multiple constituents (e.g. PAHs/TRPH). In this case, soil containing multiple constituents shall be segregated accordingly based on the constituents present in soil (e.g. soil containing PAHs/TRPH shall be placed in a separate stockpile from soil containing TRPH/PCBs). The excavated soils may be further segregated based on field observation, and field monitoring results. All potentially contaminated soils excavated will be hauled offsite for disposal or relocated and contained onsite.

HAZ-1(b) Offsite Disposal of Excavated Soil
All excavated soils to be exported offsite will be transported to an appropriately permitted licensed treatment, storage, and disposal facility (TSDF) for disposal. Potential disposal facilities include TRS (located in Azusa, California) TPS Technologies (located in Adelanto, California) or Western Environmental (located in Mecca, California.

All excavated soil to be relocated onsite, with the exception of soils affected by TPH-g at concentrations in excess of Cleanup Goals may be placed beneath publicly- owned streets, from edge of curb to edge of curb within in public right of way, Figure 20. The relocation cells will be sized and excavated based on the estimated qua ntities of the removal areas. Further, individual relocation cells will be completed to accommodate soil based on the COC present in the soil stockpile. For instance, soil containing PAHs will be placed in a dedicated relocation cell designed to contain soils contaminated with PAHs. In the case when soil is contaminated with multiple constituents (e.g. PAHs/TRPH), these soils shall be placed in a dedicated relocation cell designed to contain these types of soils (e.g. soil containing PAHs/TRPH shall be plac ed in a relocation cell separate from soil containing TRPH/PCBs). The soil excavated during construction of the relocation cells will be temporarily stockpiled onsite for subsequent reuse and for cover of the relocation cell. Upon excavation, the soil from the relocation cells will be transported to a staging area for stockpiling and subsequent sampling and analysis.
