QUALITY ASSURANCE/QUALITY CONTROL MEMORANDUM
Project: Proposed Rondo Elementary School, Eastvale, California File No.: 00727‐03
Doc. No.: 17‐02‐718
Task: PEA QA/QC Review
QA/QC Reviewed by: Scot Stormo, PG, CHG, Earth Systems Southwest Date: February 27, 2017

1.0 INTRODUCTION
This memorandum has been prepared to document the Quality Assurance/Quality Control [QA/QC] activities performed as part of the project and task referenced above. QA/QC is the process used to verify that the data obtained during testing are accurate, precise, representative, and legally defensible. QA/QC includes activities to verify the collection of high quality samples, laboratory procedures to verify the proper function of the analytical equipment, and the collection and analysis of QA/QC samples to provide a means of identifying potential problems with the quality of the data. QA/QC includes activities performed by the sample collection team, the laboratory, and the data reviewers.

2.0 PROJECT INFORMATION
The subject site consists of a former dairy farm that is proposed to be redeveloped as an elementary school. Samples have been collected and analyzed as part of a Preliminary Endangerment Assessment [PEA] to evaluate whether chemicals are present on the site that might pose a threat to the health of future students, faculty and staff. The scope of work for the PEA was developed based on the findings of a Phase I Environmental Site Assessment and discussions with DTSC staff. Compounds of potential concern [COPCs] included metals, fuels, solvents, methane, and organochlorine pesticides [OCPs]. See the PEA report for additional details.

This memorandum has been prepared to review and validate the laboratory reports for samples obtained December 6, 2016, through February 9, 2017.

3.0 METHODS

3.1 Field Activities
Field activities were reviewed to evaluate compliance with the TM and other appropriate sampling protocols, including the following:
 Documentation
 Supplies
 Decontamination
 Equipment Calibration and Maintenance
 QC Samples
 Background Samples
 Variance from the Plan

3.2 Laboratory Data Review
The data review process includes reviewing the laboratory report regarding information about the samples, and review of the QA/QC information provided with the laboratory report to identify potential problems with the data.

3.2.1 Sample Information
The review of the sample information includes the following:
 Completeness of the Laboratory Report
 Chain of Custody
 Condition of Sample Containers
 Holding Times
 Preservation
 Flags
 Case Narrative

3.2.2 Analysis Information
The analytical laboratory used for this project has internal QA/QC procedures designed to ensure the quality of their results. Those procedures are an integral part of the process to obtain certification for the various test methods. Using only certified laboratories is one of the QA/QC procedures implemented on this project. The laboratory has an internal QA/QC process for verifying the function of their analytical instruments, and it is the laboratory’s responsibility to perform those activities and correct any deficiencies identified. An audit of the laboratories internal QA/QC process was beyond the scope of this project except for: (1) Review of the QA/QC data presented in the laboratory report; and (2) Review of any “flags” attached to the laboratory data for indications of issues associated with the data.

The results of project‐specific QA/QC analyses were reviewed to look for discrepancies between the actual and target values. The QA/QC analyses performed as part of this project include internal laboratory testing of matrix spikes [MS] and duplicates [MSD]; laboratory control samples and duplicates [LCS and LCSD]); the addition of surrogates to samples for some test methods; and collecting and analyzing duplicate samples. Note that comparison of duplicate samples is discussed in the PEA report.
 MS results are obtained by spiking a portion of an actual sample with known amounts of contaminants and then analyzing the spiked sample to verify that the laboratory test can detect the compounds in the matrix being tested. This is performed mostly for organic compounds that are not naturally occurring. MS results are evaluated for both the percent recovery of the spiked compound and the “relative percent difference” [RPD] between the MS and MSD. The RPD is a measure of the difference between the two results. The RPD is equal to the difference in the two values divided by the average of the two values {(A‐B)/[(A+B)/2]}, expressed as a percent. RPD result can range from 0% (no difference in the values) to 200% (one concentration is 0 and the other is more

than 0). Liquids and gases should have RPDs of nearly 0% while the RPD of a soil can be influenced by differences inherent in the soil.
 The LCS and LCSD results are obtained by spiking a sample that is not associated with the site. The LCS and LCSD results are evaluated using the same procedure as for MS and MSD results.
 Surrogates are chemicals similar to the target analytes that are added to samples to verify that the instruments are working properly. Surrogates are evaluated by comparing the added concentration to the detected concentration to obtain the percent recovered. Surrogates are used primarily when analyzing for organic constituents, such as VOCs and OCPs.
 Duplicate samples consist of samples that are collected and handled in the same manner as the regular sample and tested for the same constituents as the regular sample collected from the same location. The results of the regular and duplicate samples are compared using the RPD. For soil samples, the “duplicate” is more properly called either a replicate or a split sample, because soil is inherently variable over small distances.

The data review process includes reviewing the laboratory report regarding information about the samples, and review of the QA/QC results as compared to the target criteria to identify potential problems with the data. The target RPDs and percent recoveries vary by chemical class and test method.

4.0 QA/QC REVIEW RESULTS
Three rounds of sample collection were conducted as part of the PEA; the first round was on December 6 through 15, 2016, the second round was on January 20, 2017, and the third round was on February 9, 2017. Most of the initial samples were analyzed immediately. Only four of the second round of samples were analyzed immediately; the others were put on “hold” as provisional samples and the laboratory was subsequently requested to analyze 6 of the held samples as the lateral and vertical extent of elevated concentrations were defined. Only two of the third round of samples were analyzed immediately while the other two samples were put on hold. In addition, samples with elevated concentrations of lead were reanalyzed to characterize the leachability of lead for disposal characterization. This resulted in a total of 9 separate laboratory reports. A table summarizing the QA/QC review results for the lab reports is attached to this document. General information regarding the reports and explanations of noteworthy features in each, are summarized below.

4.1 Field Activities
 Documentation: Field documentation consisted of logging each sample collected for laboratory analysis on a Chain‐of‐Custody form, and keeping notes of on‐site activities.

Issues of concern were not noted in the field documentation.  Supplies: Soil samples were retained in new four‐ounce glass jars with Teflon lids,

supplied by the laboratory.  Ice was used to keep the samples cold until delivery to the laboratory.   Soil gas samples were obtained in syringes (see the soil gas report for a detailed discussion of the methods used).
 Decontamination: Prior to soil sampling, the sample locations were excavated to 3 inches with a shovel, then the area was cleared with a clean stainless‐steel trowel that was decontaminated between locations.  Once the target soil was exposed, the sample jar was driven directly into the soil to obtain a “surface” soil sample.   For deeper samples, a hand‐auger was used to drill to target depth and the sample was collected from the blade portion of the auger once the target depth was reached.  The hand auger was decontaminated between depth intervals.
 Equipment Calibration and Maintenance: Electronic field equipment was not used during this sampling episode.
 QC Samples: Duplicates were collected adjacent to original samples, and therefore the depth of the sample and of the duplicate remained consistent.  A total of 14 duplicates were collected and 10 were analyzed.  The extras were collected as provisional samples but were not needed.

Field and equipment blanks were not collected as part of the soil sampling, but equipment blanks were analyzed as part of the soil gas sampling. No problems were identified in the testing of the equipment blanks.
 Background Samples: Background soil samples were not collected as part of this evaluation.
 Variance from the Plan: Variances from the TM regarding sample collection or laboratory analysis were:
o “Step‐out” samples were collected around sample location SS‐40 to evaluate the lateral and vertical extent of elevated lead concentrations detected in that sample.

The step‐out samples were collected at a spacing of 5 feet along the perimeter of the building, and a distance of 2 feet outward from the samples along the building.

Vertical step‐out samples were collected where elevated concentrations were detected in shallower samples. The vertical step‐out interval was 1 foot per round of testing.

4.2 Sample Information
 Completeness of the Laboratory Report: All submitted samples were requested to be analyzed on a normal turn‐around time or “rush” basis. Some samples were collected as provisional samples, submitted with the main samples, and put on hold at the lab.

Subsequent requests for analysis of these held samples were presented in separate laboratory reports.

 Chain of Custody: The chain‐of‐custody forms are attached and list all of the samples analyzed in each report, including time and date of collection, sample containers, matrix type, sampler’s signature, and laboratory signature.
 Condition of Sample Containers: The samples were carried to the laboratory by a courier. The report indicates the samples were received intact by the laboratory.  Holding Times: The samples were analyzed on a normal turn around or “rush” basis.

Holding times were met.
 Preservation: The soil samples were chilled prior to being delivered to the laboratory.

No other preservation technique is required for this matrix and these test methods. The soil gas samples were analyzed immediately and were not preserved.  Flags: The laboratory report was reviewed to identify if any of the data was “flagged” to indicate problems with their ability to analyze the samples. No flags were noted in the lab reports.
 Case Narrative: No comments were provided in the case narrative section of the laboratory report.

4.3 Laboratory Information
 Laboratories and Certifications: A & R Laboratories [ARL] was used to perform the soil analyses. ARL is certified for these analyses. ARL’s ELAP certification numbers are 2789, 2790 and 2122. Optimal Technology performed the soil gas survey. Optimal’s ELAP certification number is 2779.
 Analytical Methods: The samples in this laboratory report were analyzed as follows:
o Organochlorine pesticides [OCPs] using EPA method 8081A o Heavy metals using EPA method 6010B
o Mercury using EPA method 7471A
o Total petroleum hydrocarbons [TPH] using EPA method 8015 modified o Volatile organic compounds [VOCs] in soil gas using EPA method 8260B modified o Methane, oxygen and carbon dioxide ion soil gas using a Landtec GEM 2000 hand held detector
These are appropriate methods for these analytes.

4.4 QA/QC Data
The laboratory QA/QC data review is summarized in the attached table entitled Summary of QA/QC Review, with the results of each report summarized on a separate line. The quality control tests were within established limits. No problems were identified with the laboratory testing, though the soil gas survey had trouble collecting soil gas samples from a depth of 15 feet, apparently due to soils that were too “tight” to allow gases to move through them at

significant rates. This issue is not considered significant (if the soil is too tight for gas sampling, it will also be too tight for significant vapor migration).

5.0 CONCLUSIONS
The QA/QC results indicate that the analytical data are of a sufficient quality to meet the needs of this project.

3. Compliance with Conditions of Approval. Developer shall construct the Project in accordance with plans approved by City, and shall satisfy all Conditions of Approval, including without limitation, all contingencies regarding the issuance of permits, entitlements, and certificates of occupancy for the Project, which shall remain in full force and effect and unmodified by this Agreement. Developer shall comply with the Density Bonus Law by selling four (4) residential units developed within the Project to Eligible Households at Affordable Sales Prices in accordance with the terms of this Agreement.

4. Restricted Units, Income Categories. Developer hereby covenants and agrees for itself and its successors and assigns, that all of the Restricted Units shall be sold to Eligible Households at Affordable Sales Price in accordance with this Agreement. The Restricted Units shall consist of two (2) three-bedroom units and shall be restricted for sale at Affordable Sales Prices to Eligible Purchasers that qualify as Very Low Income Households. Developer agrees for itself and its successors and assigns to give priority to Eligible Households that currently reside in the City of Eastvale in the purchase of the Restricted Units, to the extent permissible under applicable state and federal laws and regulations. In connection with the sale of each Restricted Unit, the City and the homebuyer will execute a Resale Restriction Agreement that will be recorded against the Restricted Unit, the homebuyer will be obligated to execute and deliver to City an Excess Proceeds Note, and the homebuyer will be obligated to execute a Performance Deed of Trust that will be recorded against the Restricted Unit. Among other requirements, the Resale Restriction Agreement for each Restricted Unit shall provide that the Restricted Unit must be occupied as the homebuyer’s principal residence. Developer shall not sell or transfer any Restricted Unit unless and until the documents described above are executed and approved by City.

5. Phasing; Location; Amenities. The Restricted Units shall be constructed and made available for sale to Eligible Households concurrently with the Market-Rate Units throughout the construction of the Project. The Restricted Units shall not be concentrated in one location within the Project, but instead shall be dispersed throughout the Project, and shall be located as shown on the Site Plan.

This Agreement shall remain effective and fully binding regardless of any sale, assignment,

Page 1500 of 1664 ends

6 transfer, or conveyance of any of the Restricted Unit Lots or Restricted Units or any part thereof or interest therein, and shall remain in effect as to each Restricted Unit Lot until such time that each Restricted Unit is sold at Affordable Sales Prices to Eligible Households in accordance with this Agreement and a Resale Restriction Agreement is recorded against the Restricted Unit Lot.

Upon the sale of a Restricted Unit, this Agreement shall terminate and be of no further force and effect as to that Restricted Unit Lot and the Restricted Unit located thereon that has been sold in accordance with this Agreement, provided that the required Resale Restriction Agreement has been recorded against the Restricted Unit Lot.

7. No Subordination. Developer hereby represents, warrants and covenants that with the exception of easements of record, absent the written consent of City which City may grant or withhold in the exercise of its sole discretion, this Agreement shall not be subordinated in priority to any lien (other than those pertaining to taxes or assessments), encumbrance, or other interest in the Restricted Unit Lots in the Project. If at the time this Agreement is recorded, any interest, lien, or encumbrance has been recorded against any of the Restricted Unit Lots in the Project in position superior to this Agreement, upon the request of City, Developer hereby covenants and agrees to promptly undertake all action necessary to clear such matter from title or to subordinate such interest to this Agreement consistent with the intent of and in accordance with this Section 7, and to provide such evidence thereof as City may reasonably request.

8. Binding on Successors; Covenants Run with the Land. Developer hereby subjects the Restricted Unit Lots to the covenants and restrictions set forth in this Agreement. The Parties hereby declare their express intent that the covenants and restrictions set forth herein shall be deemed covenants running with the land pursuant to California Civil Code §1468, and subject to the provisions of Section 9 below, shall be binding upon and inure to the benefit of the respective heirs, administrators, executors, successors in interest, transferees, and assigns of Developer and City, regardless of any sale, assignment, conveyance or transfer of the Restricted Unit Lots or any part thereof or interest therein. So long as this Agreement remains of record, any conveyance of the Restricted Unit Lots shall be conclusively held to have been delivered and accepted subject the requirements set forth in this Agreement, without regard to whether any party to such transaction has actual knowledge of the restrictions hereof. The burden of this Agreement touches and concerns each of the Restricted Units, the Project and the Property in that the restrictions set forth herein may render the owner’s interest therein less valuable, and they enhance and increase the enjoyment and use of the Project, the Property and the Restricted Units by Eligible Purchasers who will benefit from such covenants and restrictions. Developer agrees for itself and for its successors that in the event that a court of competent jurisdiction determines that the covenants herein do not run with the land, such covenants shall be enforced as equitable servitudes against the Property in favor of City.

9. Reconveyance. Concurrently with the sale of each Restricted Unit to an Eligible Purchaser and recordation of the Resale Restriction Agreement and the Performance Deed of Trust, the Parties shall execute and record appropriate instruments to release and reconvey this Agreement as to such Restricted Unit. Such instrument shall be deposited with the escrow holder with instructions to record it concurrently with the close of escrow for the sale of the Restricted Unit to the Eligible Purchaser. Upon the sale of a Restricted Unit, this Agreement shall terminate as to that Restricted Unit and Restricted Unit Lot, provided that the required Resale Restriction has been recorded, and Developer shall be released from all obligations

Page 1501 of 1664 ends

7 hereunder except those that expressly survive termination. Nothing contained herein shall terminate Developer's obligations if any, with regard to the construction and quality of the Restricted Units, which obligations shall survive the sale of the Restricted Units and shall terminate only as provided by law.

10. Hold Harmless and Indemnification. To the greatest extent permitted by law, Developer will indemnify, defend (with counsel approved by City) and hold harmless City and its elected and appointed officials, officers, employees, agents, consultants, contractors, and board members (all of the foregoing, collectively the “Indemnitees”) from and against all liability, loss, cost, expense (including without limitation attorneys’ fees and costs of litigation), claim, demand, action, suit, judicial or administrative proceeding, penalty, deficiency, fine, order, and damage (all of the foregoing collectively “Claims”) arising directly or indirectly, in whole or in part, as a result of or in connection with or relating in any manner to the Property, the Project, the Restricted Units, or Developer's performance or non-performance under this Agreement, except to the extent arising from the gross negligence or willful misconduct of the Indemnitees. The provisions of this Section shall survive the expiration or other termination of this Agreement and the release of part or all of the Property from the burdens of this Agreement.

11. Default; Remedies. In the event of any breach of this Agreement, the non-defaulting Party shall provide written notice of default to the Party in default. If the default is not cured within thirty (30) days after delivery of such notice, or in the case where the default cannot be cured within thirty (30) days and the defaulting party does not diligently and continuously pursue a cure of the default until the default is cured, then the non-defaulting Party shall have the right to take legal or other action to enforce this Agreement, including without limitation, bringing an action for equitable relief seeking the specific performance of the terms and conditions of this Agreement, and/or enjoining, abating, or preventing any violation of such terms and conditions, and/or seeking declaratory relief or damages. Each of the remedies provided herein is cumulative and not exclusive, and each Party may exercise from time to time any rights and remedies available to it under applicable law or in equity, in addition to, and not in lieu of, any rights and remedies expressly provided in this Agreement.

12. Fair Housing; Non-Discrimination. Developer shall comply with all applicable State and federal fair housing laws in the marketing and sale of all residential units in the Project.

Developer shall not restrict the rental, sale, lease, sublease, transfer, use, occupancy, tenure or enjoyment of the Property, the Project, or any portion thereof, on the basis of race, color, religion, creed, sex, sexual orientation, disability, actual or perceived gender identity, marital status, ancestry, or national origin of any person. Developer covenants for itself and all persons claiming under or through it, and this Agreement is made and accepted upon and subject to the condition that there shall be no discrimination against or segregation of any person or group of persons on account of any basis listed in subdivision (a) or (d) of Section 12955 of the Government Code, as those bases are defined in Sections 12926, 12926.1, subdivision (m) and paragraph (1) of subdivision (p) of Section 12955, and Section 12955.2 of the Government Code, in the sale, lease, sublease, transfer, use, occupancy, tenure or enjoyment of the Property or part thereof, nor shall Developer or any person claiming under or through Developer establish or permit any such practice or practices of discrimination or segregation with reference to the selection, location, number, use or occupancy of tenants, lessees, subtenants, sublessees or vendees in, of, or for the Property or part thereof. Developer shall include such provision in all

Page 1502 of 1664 ends

8 deeds, leases, contracts and other instruments executed by Developer, and shall enforce the same diligently and in good faith.

13. Mortgagee Protection. No violation of any provision contained herein shall defeat or render invalid the lien of any mortgage or deed of trust made in good faith and for value upon all or any portion of the Project or the Property, and the purchaser at any trustee’s sale or foreclosure sale shall not be liable for any violation of any provision hereof occurring prior to the acquisition of title by such purchaser. Such purchaser shall be bound by and subject to this Agreement from and after such trustee’s sale or foreclosure sale.

14. Miscellaneous.

RESOLUTION NO. 26-XX

A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF EASTVALE, CALIFORNIA,

APPROVING THE DENSITY BONUS AND DEVELOPMENT STANDARD WAIVERS, TENTATIVE TRACT MAP NO. 39416, AND THE MASTER SITE PLANNING AND ARCHITECTURE OF A 35 UNIT SINGLE FAMILY RESIDENTIAL COMMUNITY, WITH

PARKING AREAS, LANDSCAPING, AND OPEN SPACE LOCATED AT THE NORTHEAST CORNER OF WALTERS STREET AND HELLMAN AVENUE. ASSESSORS PARCEL NUMBERS 144-070-016, 144-070-017, 144-070-018, AND 144-070-020.

WHEREAS, the Planning Department of the City of Eastvale received an application (PLN26-20102) on December 10, 2025, from Regent Land Company, LLC (the “Applicant”) requesting approval of Tentative Tract Map 39416, Major Development Review, and a density bonus and development standards waivers to allow for the construction of a new 35-unit single family residential community, two (2) of which are proposed as very low-income affordable units, with associated parking areas, landscaping, and open space (the “Project”); and WHEREAS, the proposed project (Project No. PLN25-20102) is considered a “Project” as defined by the California Environmental Quality Act, Public Resources Code Section 21000 et seq.; and
WHEREAS, review of the proposed project with respect to the proposed uses was evaluated in a Section 15183 Exemption Report and the General Plan Environmental Impact Report (State Clearinghouse No.2022080090), because the implementation of the proposed project would not result in new or more severe impacts to the environment beyond what was previously evaluated and disclosed by the General Plan EIR, no additional environmental review beyond a Section 15183 Exemption Report is necessary; however, a Notice of Exemption will be filed following any action taken on the project; and
WHEREAS, the Housing Accountability Act (HAA) provides that “a proposed housing development project is not inconsistent with the applicable zoning standards and criteria, and shall not require a rezoning, if the housing development project is consistent with the objective general plan standards and criteria but the zoning for the project site is inconsistent with the general plan.” In such cases, the local agency may require the proposed housing development project to comply with the objective standards and criteria of the zoning district that is consistent with the general plan; and
WHEREAS, the R-1 (One Family Dwelling) zoning designation is consistent with the General Plan land use designation for the property of Single-Family Low and the objective standards and criteria applicable within the R-1 district will apply to the project as those standards existed on October 9, 2025, the date an SB 330 preliminary application for the Project was submitted; and

Page 1511 of 1664 ends

WHEREAS, the applicant has filed for a 22.5% Density Bonus per Section 120.05.090(b)(2) and (d)(1)(b) of the Eastvale Municipal Code by setting aside at least six percent (6%) of the total units before the density bonus is granted within the project for very-low income households. The California Density Bonus law (Government Code section 65915) allows developers whose projects qualify for a density bonus to request the city waive any development standards that “will have the effect of physically precluding the construction” of the project at the density permitted by the Density Bonus Law; and
WHEREAS, the applicant proposes to set aside two (2) of the 29 base density units permitted under the General Plan density for the 3.57 acre site for purchase by very low income households, making the project eligible for a 22.5% increase in density, or up to 35 units on the

3.57 acre site. The developer has requested ten (10) development standard waivers ( reduction in minimum lot size, lot width, lot depth, front yard setback, interior side yard setback, street side yard setback, and street width, in addition to a request to increase the maximum fence height, and waive the requirement for a minimum of one two-story plan type and have garages plotted at varying distances from the street); and
WHEREAS, the State Density Bonus law does not provide the City with discretion to deny a density bonus request if that request is consistent with the requirements of the State Density Bonus law, and a request to waive development standards that physically preclude the construction of the project can only be denied if “the waiver or reduction would have a specific, adverse impact, as defined in paragraph (2) of subdivision (d) of Section 65589.5, upon health or safety, and for which there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact”; and
WHEREAS, on May 10, 2026, the City of Eastvale City Clerk published a legal notice in compliance with state law concerning PLN25-20102 in the Press Enterprise, a local newspaper of general circulation, regarding the Planning Commission meeting on May 20, 2026. In addition, on May 7, 2026, a public hearing notice was also mailed to commercial tenants and residents within a 600-foot radius of the projects site indicating time, date, and place of the public hearing for PLN25-20102; and
WHEREAS, the City of Eastvale Planning Commission conducted a duly noticed public hearing on May 20, 2026, at which time it received public testimony concerning Project No.

PLN25-20102 and considered the proposed Tentative Tract Map, Major Development Review for the master site planning and architecture of the Project, density bonus and development standard waivers and recommended that the City Council disapprove the Project; and WHEREAS, on June 14, 2026, the City of Eastvale City Clerk published a legal notice in compliance with state law concerning PLN25-20102 in the Press Enterprise, a local newspaper of general circulation, regarding the City Council meeting on June 24, 2026. In addition, on June 11, 2026, a public hearing notice was also mailed to commercial tenants and residents within a 600- foot radius of the projects site indicating time, date, and place of the public hearing for PLN25- 20102; and

Page 1512 of 1664 ends

WHEREAS, the City of Eastvale City Council conducted a duly noticed public hearing on June 24, 2026, at which time it received public testimony concerning Project No. PLN25-20102 and continued the public hearing to the September 9, 2026, regularly scheduled City Council meeting; and
WHEREAS, the City of Eastvale City Council conducted a duly noticed public hearing on September 9, 2026, at which time it received public testimony concerning Project No. PLN25- 20102, and considered the proposed Tentative Tract Map, Major Development Review for the master site planning and architecture of the Project, density bonus, and development standard waivers.

NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF EASTVALE, DOES HEREBY FIND, DETERMINE, AND RESOLVE AS FOLLOWS:

SECTION 1. ENVIRONMENTAL FINDINGS
Pursuant to the California Environmental Quality Act, including Public Resources Code Sections 21080(e) and 21082.2, and based on the record and/or as provided at the public hearing, the City Council hereby finds and determines that the project was adequately analyzed according to the CEQA Guidelines, as supported by the following Findings and Evidence:

Finding 1: The proposed project is exempt from further environmental review requirements.

Evidence: Pursuant to California Environmental Quality Act (CEQA) Guidelines Section 15183, because implementation of the proposed project would not result in impacts that are peculiar to the project site and the proposed project would not result in new or more severe impacts to the environment beyond what was previously evaluated and disclosed by the General Plan EIR (SCH # 2022080090), no additional environmental review beyond a Section 15183 Exemption Report is required for the proposed project. A Section 15183 Exemption Report was prepared for the project supporting this conclusion, a copy of which is included in the record for this project and incorporated herein by reference. As such, no further CEQA documentation would be warranted for the proposed project pursuant to CEQA Guidelines Section 15183.

SECTION 2. FINDINGS FOR VESTING TENTATIVE TRACT MAP NO. 39416 Pursuant to Eastvale Municipal Code Section 130.12.190, the staff reports dated June 24, 2026, and September 9, 2026, and all evidence and testimony heard at the public hearing of this item, the City Council hereby finds and determines as follows:

Finding 1: Tentative Tract Map No. 39416 is consistent with the City’s General Plan and any applicable specific plan as specified in Government Code Section 65451.

Page 1513 of 1664 ends

Evidence: The proposed project and its design and improvements will be consistent with the Chandler Policy Area designation of the General Plan and are otherwise consistent with all other elements of the General Plan and any applicable specific plans. The proposed subdivision of land will create 35 single family residential lots, two (2) open space lots, and four (4) lots for street purposes consistent with the various provisions of the General Plan. While 35 units exceeds the density permitted on the site under the General Plan, the project is utilizing the State of California’s Density Bonus Law to allow for an increase in density of up to a twenty-two and a half percent (22.5%), resulting in an increase of six (6) single family residential lots from what is allowed under the General Plan land use designation. The maximum unit yield for the 3.57-acre site using the Single-Family Low General Plan density and the State density bonus is 35 units, and the applicant is proposing to develop 35 units on the site; therefore, the tentative map reflects the allowable density under Density Bonus Law.

Finding 2: The design or improvement of the proposed subdivision is consistent with the City’s General Plan and any applicable specific plan.

Evidence: The proposed project is designed to meet all City standards applicable to residential development within the Single-Family Low land use designation and R1 zoning district, except where a waiver is being granted pursuant to the State Density Bonus law, including drainage, utilities, grading, required dedications and providing satisfactory pedestrian and vehicular circulation, emergency vehicle access and on- and off-site public improvements.

Finding 3: The site is physically suitable for the type and proposed density of development.

Evidence: The site is physically suitable for the type and density of the proposed development. The proposed site consists of approximately 3.57-acres of land and is physically suitable for the proposed development, where access to the site will be from Walters Street and Hellman Avenue. The current General Plan land use designation of the project site is Chandler Policy Area, which applies to residential areas characterized by single-family housing. The General Plan density would allow up to 8 dwelling units per acres (du/ac). The proposed density is 9.8 du/ac, which would be permitted through Density Bonus Law through a separate density bonus agreement. The proposed density is below the Density Bonus Law provisions in the California Density Bonus Law for low-income projects (22.5 percent density bonus) which allows 9.8 du/ac on the project site. The applicant has submitted a conceptual development plan which illustrates that single-family dwelling units can be constructed on this 3.57-acre site without adversely affecting the health, safety, or welfare of anyone who will live within the development or anyone living within the surrounding community. Further, the infrastructure and utilities either already serve the site or can be readily expanded to serve the site, and there are no intractable topographical peculiarities

Page 1514 of 1664 ends

associated with the physical character of the property that may prevent the development of thirty-five (35) lots with single family dwellings, two (2) for open space purposes and four (4) for street purposes.

Finding 4: The design of the subdivision or proposed improvements is not likely to cause significant environmental damage or substantially and avoidably injure fish or wildlife or their habitat.

Evidence: A Biological Resources assessment and Western Riverside County MSHCP Consistency Determination dated February 2026 were prepared for the proposed project. In said document no sensitive vegetation communities, potentially jurisdictional areas, special-status plant species or MSHCP riparian/riverine areas were observed on site. Further no Burrowing Owel were observed. Portions of the project site and the immediate surrounding area provide suitable habitat for nesting birds although no nesting birds were observed on site. However, site development conditions such as biological resource monitoring, preconstruction nesting bird surveys, preconstruction Burrowing Owl surveys, and implementing best management practices were identified and conditioned on the project to avoid or mitigate any potential significant effects on the environment to a point below the threshold of significance. As conditioned, the project will not have a significant effect on the environment or substantially and avoidably injure fish or wildlife or their habitat.

Finding 5: The design of the subdivision or type of improvements is not likely to cause serious public health problems.

Evidence: The design of the subdivision is in conformance with the City’s General Plan, Zoning Code, and Subdivision Ordinance to the extent permitted under the HAA and State Density Bonus Law. Accordingly, the subdivision and improvements will comply with all applicable local, state, and federal laws to ensure the public’s general health, safety, and welfare
Finding 6: The design of the subdivision or the type of improvements will not conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision.

Evidence: The design of the subdivision and type of improvements will not conflict with easements, acquired by the public at large, for access through or use of the property within the proposed subdivision. Upon review of the project by the Engineering Division, there is no, known conflict with any easements, or right-ofways an all in-tract streets are to be private streets with access easements for emergency personnel only.

SECTION 3. FINDINGS FOR MAJOR DEVELOPMENT REVIEW PLN24-20053

Page 1515 of 1664 ends

Pursuant to Section 120.02.010(c)(6) of the Eastvale Municipal Code, and in light of the record before it, including the staff reports dated June 24, 2026, and September 9, 2026, and all evidence and testimony heard at the public hearing of this item, the City Council hereby finds and determines as follows:

Finding 1: The proposed project is consistent with the objectives of the general Plan and complies with applicable zoning regulations, specific plan provisions, special planning area provisions, design guidelines, and improvement standards adopted by the city.

Evidence: The General Plan land use designation of the proposed site is Single Family-low.

The Single Family-Low land use designation allows for the development of singlefamily residential development with a maximum density of eight (8) dwelling units per acre. Therefore, the proposed project would be consistent with the General Plan designation for the site with the application of State Density Bonus Law and will further the objectives of the General Plan. Finally, the proposed project would be consistent with the surrounding area and is consistent with the General Plan and Zoning to the extent permittable under the provisions of the HAA and State Density Bonus law.

Finding 2: The proposed architecture, site design, and landscape are suitable for the purposes of the building and site and will enhance the character of the neighborhood and community.

Evidence: The proposed project has been designed to conform to the logical pattern of development as envisioned by the Eastvale General Plan and has been designed to satisfy the General Plan design policies. The project has been designed with high-quality urban design, architecture and landscaping that includes landscape streetscapes, three architectural styles (i.e., Cottage, Farmhouse, Monterey), and connectivity between existing street networks for pedestrian and bicyclists.

Finally, the project has been designed to meet the requirements and development standards of the Eastvale Zoning Code to the extent permitted under the HAA and State Density Bonus law. For these reasons, the proposed project, as conditioned will enhance the character of the neighborhood and community.

Finding 3: The architecture, including the character, scale, and quality of design, relationship with the site and other buildings, building materials, colors, screening of exterior appurtenances, exterior lighting, and signing and similar elements, establishes a clear design concept and is compatible with the character of buildings on adjoining and nearby properties.

Evidence: The architectural theme of the proposed single-family residential units are consistent with the surrounding neighborhoods in terms of character, scale, and

Page 1516 of 1664 ends

quality to the extent allowed under the HAA and State Density Bonus law. These standards focus on high quality design and articulation to provide visual interest and variety. The buildings include board and batten, shutters, flower boxes, decorative vents and exterior lights as examples of variation of materials designed to complement the exterior plaster and building finishes. Thus, the proposed design is consistent with the Eastvale Zoning Code and the General Plan.

Finding 4: The proposed project will not create conflicts with vehicular, bicycle, or pedestrian transportation modes of circulation.

Evidence: The proposed project is conditioned to ensure adequate circulation to and from the site. All streets have been designed to handle the type and quantity of vehicular traffic associated with the proposed project. As conditioned, the project will include sidewalks and pedestrian and bicycle connections that will not create conflicts with motorized vehicles. Rondo Elementary School of Discovery is located across Walters Street directly south of the project site, providing convenient, walkable access for school-aged children within the proposed development to get to school. However, Walters Street is currently impacted with significant vehicular traffic and queuing during peak drop-off and pick-up times and there is concern that queuing may spill into the project site upon completion, creating additional conflicts and impacting future residents. To help minimize this concern, the applicant will install No Parking, vehicles subject to tow signage to discourage queuing. The City Engineer, Riverside County Sheriff’s, and Fire Department have reviewed the proposed project access and on-site circulation design and do not have any concerns about the project itself.

Finding 5: The proposed project is consistent with the most recently adopted version of the Chino Airport Land Use Compatibility Plan.

Evidence: The project has been reviewed for consistency with the Airport Land Use Compatibility Plan. The project is located within the Chino Airport Influence Area Zone D. No limitations and prohibited uses related to the proposed project were identified.

SECTION 4. STATE DENSITY BONUS LAW
Pursuant to Section 120.05.090 of the Eastvale Municipal Code and the State Density Bonus law, and in light of the record before it, including the staff reports dated June 24, 2026, and September 9, 2026, and all evidence and testimony heard at the public hearing of this item, the City Council hereby finds and determines that the project as proposed satisfies the eligibility criteria for a 22.5% density bonus by setting aside at least 6% of the base density units permitted prior to the density bonus for very-low income households, and that the ten (10) requested development standard waivers are appropriate and ensure the project is not physically precluded from being developed at the increased density provided under the State Density Bonus Law. .

Page 1517 of 1664 ends

SECTION 5. MULTIPLE SPECIES HABITAT CONSERVATION PLAN (MSHCP) The project is found to be consistent with the MSHCP. The project is located outside of any MSHCP criteria area, and mitigation is provided through payment of the MSHCP Mitigation Fee.

SECTION 6. RECORD OF PROCEEDING
The documents and other materials that constitute the record of the proceedings upon which the City Council’s decision is based, which include but are not limited to the staff reports as well as all materials that support the staff reports for the proposed project, are located in the City Clerk’s office of the City of Eastvale at 12363 Limonite Avenue, Suite 910, Eastvale, CA 91752.

The custodian of these documents is the City Clerk of the City of Eastvale.

The consulting archaeologist shall have the authority to modify the monitoring program if the potential for cultural resources appears to be less than anticipated.

2. Isolates and clearly non-significant deposits will be minimally documented in the field so the monitored grading can proceed.
