INTRODUCTION
The subject of this appeal is an Excavation Permit issued by the Public Works Department for the installation of Southern California Edison (SCE) electrical utility infrastructure along South Santa Monica Boulevard from Wilshire Boulevard to Charleville Boulevard. The upgraded electrical infrastructure will serve the One Beverly Hills Project at 9900 Wilshire Boulevard and will be part of SCE’s Executive Circuit which serves the western portion of the City.

On August 14, 2026, Victor De la Cruz of Mannatt, Phelps & Phillips, LLP, on behalf of The Belvedere Hotel Partnership dba The Peninsula Beverly Hills, filed an appeal of the Meeting Date: September 22, 2026

issuance of the Excavation Permit (Attachment 1). The appeal alleges that the extent and duration of the construction would create unacceptable operational, scheduling, noise, vibration, traffic, and reputational impacts to the Peninsula hotel. The appeal also alleges that the location of the SCE utility alignment violates conditions of approval associated with the 9900 Wilshire project entitlements, and that further environmental analysis is required.

On September 1, 2026, the City Council scheduled a public hearing for September 22, 2026 for the Council to consider the appeal.

DISCUSSION
On August 7, 2026, the Public Works Department in conjunction with Community Development Major Projects issued an Excavation Permit (Attachment 2) to allow excavation and installation of SCE electrical conduit and vaults within the public right of way along South Santa Monica Boulevard from the intersection of Wilshire Boulevard to the intersection of Charleville Boulevard. The utilities proposed under the permit in question are associated with the Edison infrastructure upgrades required to provide service to the One Beverly Hills project.

Right-of-Way Permitting Process
Work within the public right-of-way — including the installation of underground electrical conduit, vaults, and related facilities — requires an excavation permit issued by the Public Works Department under Beverly Hills Municipal Code (BHMC) Title 8, Chapter 2.

In carrying out the application review for an excavation permit, staff evaluates how the proposed work interacts with existing utilities and the available right-of-way, including roadway capacity and corridor limitations. Staff reviews the proposed alignment and supporting traffic control plans, identifies required traffic-control measures and construction scheduling, determines appropriate notification and outreach to affected businesses and residents, reviews any applicable environmental documents, and evaluates the adjustments or concessions necessary to minimize impacts to the public.

Conditions of approval are attached to the permit to carry those requirements into the field.

Specifically regarding the review of excavation permits for utilities, the City’s role in permit plan review is not to evaluate the utility’s proposed engineering solution, but to exercise the City’s responsibility as steward of the public right-of-way, confirming that the proposed installation can be accommodated within the right-of-way and requiring reasonable, justified adjustments to the plan or conditions for the work where necessary to protect the right-of-way, traffic, access, safety, the environment and other public needs.

Typical items considered during the review include, but are not limited to, the following:
 Contractor licensing appropriate to the scope of work  Insurance certificates and bonds
 Correct permit type/class for the scope; fees and deposits collected  Other required permits/approvals identified (encroachment, building, hauling, dewatering)
 Stormwater erosion control Best Management Practices (BMPs)  Dust, noise, and hours-of-work ordinance compliance; sanitation/refuse continuity  Existing utility locations and required horizontal/vertical clearances (water, sewer, storm, gas, electric, and communications)
Meeting Date: September 22, 2026

 Depth of cover, bedding, and backfill specifications; siting of vaults/boxes/manholes clear of other facilities and their access  Trench section, excavation safety/shoring, and traffic/structural loading appropriate to the location
 Connection/tap approvals and inspection requirements where tying into City mains  Curb ramp, driveway, sidewalk, and curb-and-gutter impacts  Tree protection zones and Arborist coordination if street tree roots may be impacted
 Impacts to roadway pavement, sidewalks, signs, striping, signals, streetlights, and other surface assets
 Traffic impacts and adequate traffic control plan per the Manual on Uniform Traffic Control Devices (MUTCD) and City standards; approved lane/parking closures, work hours, and haul routes
 Vehicular travel and emergency access; property, driveway, and business access  Mitigation measures, if any
 Americans with Disabilities Act (ADA)-compliant pedestrian access maintained during construction, including detours and temporary accommodations; transit stop and loading-zone impacts addressed
 No-parking posting protocol and required notifications  Pavement moratorium; trench cut policy/T-section restoration  Restoration to City standard with warranty and guarantee; dig-out/repave limits; ADA upgrades as required by Public Right-of-Way Accessibility Guidelines (PROWAG)
Review of Permit PW2600515
Proposed Work
Utility infrastructure (e.g., water, sewer, power, gas, telecommunications) is designed and engineered by the utility provider. As the responsible engineer for its own facilities, SCE retains authority over the engineering design of its electrical system, and applicants bring forward an SCE-engineered plan set for the City’s review.

The proposed work consists of the installation of approximately 795 linear feet of underground electrical conduit and two underground electrical vaults within South Santa Monica Boulevard between Wilshire Boulevard and Charleville Boulevard, together with approximately 50 linear feet of conduit within Charleville Boulevard. The vaults are precast concrete structures (7′ × 14′ × 8′), one located toward the Wilshire Boulevard end of the segment and one toward the Charleville Boulevard end. The proposed work is estimated to take 39 days (35 active construction days) to complete.

The project plans were prepared by a third-party designer approved by SCE and were subsequently reviewed and approved by SCE. As the responsible engineer for its facilities, SCE determines the routing of its electrical infrastructure. The alignment along South Santa Monica Boulevard was presented to the City as SCE’s preferred alignment.

Traffic and Right-of-Way Considerations
Two major-intersection crossings were central to the alignment evaluation: a potential crossing of North Santa Monica Boulevard and the crossing of Wilshire Boulevard at South Santa Monica Boulevard. The alignment was evaluated based on many factors, including, but not limited to, roadway capacity, traffic volumes, duration of construction, and impacts to major intersections.

Meeting Date: September 22, 2026

Although the alignment was originally proposed by SCE, it minimizes overnight impacts to residences. Approximately half of the alignment was anticipated to require daytime construction. Locating this longer-duration work on the lower-volume roadway (South Santa Monica Boulevard traffic volume is around 50% of the traffic volume on North Santa Monica Boulevard) would reduce impacts to the traveling public and the surrounding street network.

The alignment also has pavement-management benefits for the preservation of public roadway infrastructure. The intersection of North Santa Monica Boulevard, including the intersection with Wilshire Boulevard, was reconstructed about seven years ago and is not anticipated to require resurfacing for several more years; whereas Wilshire Boulevard, including the intersection of South Santa Monica Boulevard, is part of an active project by the City and is scheduled to be resurfaced this fall. Sequencing the proposed SCE utility work ahead of the programmed resurfacing avoids trenching and patching newer pavement and yields a uniform, long-lasting final roadway surface.

City-Required Design Refinement
During the City’s review, the City required that the SCE vaults and access hatches be relocated to fall within a single travel lane rather than straddling two travel lanes. This adjustment was intended to minimize future traffic impacts by allowing routine maintenance and emergency access to be accommodated within a single, more contained work area, reducing the extent of lane closures required over the life of the facilities.

Specific Plan Condition
In the appeal, Mr. De la Cruz has cited to a condition in the superseded Specific Plan for the 9900 Wilshire project. He argues that the condition limits utility work to the adjacent streets and alleys.

Of course, that condition was placed on a different project, and that project is not moving forward. However, there is a similar condition the One Beverly Hills Overlay Specific Plan.

That condition reads: “[t]he Developer shall underground, if necessary, the utilities in adjacent street and alleys per requirements of the Utility Company and the City.” (Condition 18 of the Standard Conditions).

This standard condition is not meant to limit utility work to adjacent streets and alleys but instead to require a developer, if necessary, to underground those utilities that are located adjacent to the project.

Environmental Assessment
Since the work authorized by the permit is part of the implementation of the One Beverly Hills Overlay Specific Plan, environmental assessment pursuant to the California Environmental Quality Act (CEQA) was substantially covered by the previously certified Final Supplemental Environmental Impact Report (SEIR) for the project. In order to ensure that the scope of work for this SCE segment did not require any additional environmental review, Addendum #4 to the SEIR (Attachment 3) was prepared to study potential impacts.

Addendum #4 found that no new information would suggest that the project will have one or more significant effects not previously discussed in the SEIR; significant effects previously examined will not be substantially more severe than shown in the SEIR; there were no mitigation measures or alternatives previously found not to be feasible, which would in fact be feasible and would substantially reduce one or more significant effects of the project; and there are no new mitigation measures or alternatives, which are Meeting Date: September 22, 2026

considerably different from those analyzed in the SEIR that would substantially reduce one or more significant effects on the environment.

Conditions to Minimize Impacts
The permit was issued with conditions directed at minimizing construction impacts to adjacent properties and the traveling public. The construction impacts identified in the appeal — including noise, vibration, traffic, and access — were analyzed in Addendum #4 to the SEIR, and, even though they are not considered new or substantially more severe significant impacts, they are addressed through these conditions of approval.

Conclusion
Based on the foregoing discussion, staff believes that Excavation Permit PW2600515 was reviewed and issued appropriately and in accordance with BHMC Title 8, Chapter 2.

Furthermore, staff believes that the proposed alignment is appropriately accommodated within the public right-of-way in a manner that protects the public infrastructure investment, and that the proposed construction impacts were evaluated and adequate conditions were applied to the permit and associated traffic control plan to minimize those impacts on nearby properties and the traveling public. Staff therefore recommends that City Council deny the appeal and uphold issuance of Excavation Permit PW2600515.

FISCAL IMPACT
There is no anticipated fiscal impact to the City.

Re: Appeal of Permit PW2600515 for Off-Site Electrical Infrastructure — One Beverly Hills Project
Dear Honorable Mayor Corman and City Council:

This firm represents The Belvedere Hotel Partnership dba The Peninsula Beverly Hills (the “Peninsula”). Pursuant to Beverly Hills Municipal Code (“BHMC”) Sections 8-2-19 and 1- 4-101, on behalf ofthe Peninsula, we are appealing Permit PW2600515 (Exhibit A), which was issued to the developer ofthe One Beverly Hills project, Cain International (“Cain”), on Friday, August 7, 2026. The Permit authorizes trenching and installation of off-site electrical infrastructure within the South Santa Monica Boulevard public right-of-way for the One Beverly Hills project (the “Proposed Work”) directly in front of the Peninsula. In compliance with BHMC Section 1-4-101(C), on August 11, 2026, this firm notified the City Engineer and City Manager in the presence of the City Attorney that it would be filing the subject appeal. The City Attorney confirmed that such oral notification satisfied the condition precedent in BHMC Section 1-4-10 1(C) for filing this appeal.

The Peninsula has made it eminently clear to the City and Cain on various occasions that the significant period oftime that South Santa Monica Boulevard would be subject to lane closures and construction for the Proposed Work would create unacceptable operational and scheduling problems, including violations of existing commitments to guests and hotel partners.

The significant and untenable noise, vibration, and traffic impacts on the Peninsula’s guestswould further create immense reputational damage and financial harm to the Peninsula. With the Peninsula’s Verandah Room being directly on South Santa Monica Boulevard, for example, scheduled weddings, conferences, and events would likely be cancelled, and in turn, this wouldresult in significant room blocks (often forty-plus rooms) being cancelled too. Further, partnerssuch as American Express and Chase Visa require significant advance notice of any renovationsor disruptions that could affect the quality of guest stays, and certain rooms and villas directly on South Santa Monica Boulevard could not possibly be rented out during the Proposed Work.

Nevertheless, in an effort to be as neighborly as possible, the Peninsula has been engaging in good faith discussions with Cain over a period of several months, hired dry utility Manatt, Phelps & Phillips, LLP 2049 Century Park East, Suite 1700, Los Angeles, California 90067 Tel: 310.312.4000 Fax: 310.312.4224 manatt

experts to evaluate the feasibility of relocating the Proposed Work to North Santa Monica Boulevard, and offered to pay Cain the difference in costs resulting from any relocation. For those reasons, the Peninsula was shocked by the issuance of the Permit given that as recently as June 9. 2026, Cain informed the Peninsula that relocating the Proposed Work from South Santa Monica Boulevard to North Santa Monica Boulevard should be viable. So incredibly important to the Peninsula is the relocation ofthe Proposed Work to North Santa Monica Boulevard thatthe Peninsula even committed in writing to paying the incremental costs for that relocation work to the tune of approximately $750,000 even though the Proposed Work in no way benefits the Peninsula. (Exhibit B.) In other words, despite the Peninsula’s willingness to pay for theProposed Work to be relocated and such relocation being feasible, a decision was made to reject the PeninsuL&s pleas for help, ignore its significant offer of financial assistance, and keep the Peninsula in the dark until after the new Permit was issued.

We have been informed by the City Manager that South Santa Monica Boulevard was selected over the Peninsula’s objections because it is more convenient to existing Southern California Edison infrastructure, would better serve future needs in the area, and would betteralign with future planned street paving schedules. However, the Peninsula and its dry utility expert team has not seen anything that would support those assertions or that would demonstrate the degree to which moving the Proposed Work just a few feet north would compromise such future needs. And importantly, no effort was made to engage with the Peninsula in a discussion about these issues to explore solutions or better assess whether they overrode the Proposed Work’s potentially catastrophic impacts on the Peninsula. The Peninsula understands that the City must consider overall infrastructure needs in making decisions about utilities; however, it is a mistake to completely ignore major City stakeholders and their long-term tax revenuegeneration for any perceived short-term gain.

As we have previously informed the City, Condition No. 8, adopted as part ofthe City Council’s approval ofthe Amended and Restated 9900 Wilshire Specific Plan (Resolution No. l6-R-13 118, Exhibit C), requires the Applicant to underground utilities in “adjacent streets and alleys.” By its terms, the condition is limited to streets directly adjoining the project site and does not authorize utility work beyond that geographic scope.’ The Permit cannot be issuedwithout first amending the OBH project’s entitlements. Furthermore, having reviewed the recently issued Addendum #4 to the Final Supplemental Environmental Impact Report for the ‘South Santa Monica Boulevard is not adjacent to the One Beverly Hills project site. The site is bounded by Wilshire Boulevard and Santa Monica Boulevard and is bisected by Merv Griffin Way, which together constitute the streets directly adjoining the site and forming the basis ofthe project’s circulation and infrastructure analysis in the SEIR. South Santa Monica Boulevard is physically separated from theproject site and is not identified as a project frontage or adjacent Street in the project approvals or environmental review.

One Beverly Hills Overlay Specific Plan Project (the “SEIR”), it is abundantly clear that thedocument is riddled with flaws that render it meaningless as an informational document under the California Environmental Quality Act (“CEQA”), not the least of which is that the noise and vibration analysis, among others, conceal the Proposed Work’s true impacts. Simply stated, a new Supplemental EIR and public circulation is required to comply with CEQA.

Despite the aforementioned legal violations, the Peninsula remains willing to continue engaging with Cain to explore a potential amicable resolution outside ofthe City Council appeal process. Accordingly, while such discussions continue, at this time we are limiting the contentsofthis appeal as an indication of our good faith in these discussions. However, the Peninsula reserves the right to supplement its appeal before any City Council hearing on the appeal and reserves all rights and remedies, waiving none.

Dear Jonathan,
Thank you for your update of June 9th and your indication that relocating the SCE electric line is doable.

Subject to verification, Peninsula is willing to pay all direct, valid costs which you would incur to relocate the SCE line to North Santa Monica Boulevard, above and beyond the costs you would have incurred had the project gone forward, as you originally proposed on South Santa Monica Boulevard.

We presume you arrive at the $750,000 cost estimate after conducting an in-depth review of the costs. In your email you stated that you can provide “evidence” supporting such
estimate. We would appreciate receiving at your earliest convenience details of all such evidence for our review, including the details of your cost estimate, as well as detailed evidence of the electric line project costs, as originally proposed on South Santa Monica Boulevard.

We look forward to receiving the above information at your earliest convenience.

My best wishes,Robert

Dear Robert
I committed to you in our meeting [ate April that, at your request, we would look at relocating the SCE conduit from South Santa Monica Boulevard to North SantaMonica Boulevard and keep you apprised of what we found. In our meeting, and your subsequent email of May 19, you agreed to cover any extra costs to reroute the line.

There are positive signs that the relocation is viable and our current estimate ofthe incremental costs for moving the SCE conduit will be in the range of $750,000. We can of course evidence this to you.

Please reconfirm that ifwe are able to accomplish this relocation, Peninsula agrees to pay the increased costs. We would bill you during the course of the work. Once we have received this confirmation we will proceed to finalise with SCE.

I look forward to hearing from you on this issue and would be happy to discuss.Regards JonathanJonathan GoldsteinChief Executive Officer

To: Robert Zarnegin <[email protected]> Cc: Larry Green Cain Dev <[email protected]> Subject: One Beverly Hills - SCE Conduit Dear Robert
I committed to you in our meeting late April that, at your request, we would look at relocating the SCE conduit from South Santa Monica Boulevard to North Santa Monica Boulevard and keep you apprised of what we found. In our meeting, and your subsequent email of May 19, you agreed to cover any extra costs to reroute the line. There are positive signs that the relocation is viable and our current estimate of the incremental costs for moving the SCE conduit will be in the range of $750,000. We can of course evidence this to you. Please reconfirm that if we are able to accomplish this relocation, Peninsula agrees to pay the increased costs. We would bill you during the course of the work. Once we have received this confirmation we will proceed to finalise with SCE. I look forward to hearing from you on this issue and would be happy to discuss. Regards Jonathan Jonathan Goldstein

PROJECT DESCRIPTION:

The One Beverly Hills Overlay Specific Plan (“Specific Plan”or “Approved Project”) sets forth land use and development standards for the properties located at 9850, 9876, 9900, and 9988 Wilshire Boulevard (“Project site”) in the City of Beverly Hills (“City”). The Specific Plan was approved by the City Council in 2021 through the adoption of Resolution 21-R-13349 amending the General Plan; Resolution 21-R-13350 adopting the One Beverly Hills Overlay Specific Plan; Ordinance 21-O-0238 amending the Zoning Code; and Ordinance 21-O-2839 approving a Development Agreement. As part of the project approvals, the City also certified a Final Supplemental Environmental Impact Report1 (“SEIR”, State Clearinghouse No. 2020090048), adopted a Mitigation Monitoring and Reporting Program MMRP, and adopted a Statement of Overriding Considerations through the adoption of City Council Resolution No. 21-R-13348.

Buildout of the Approved Project is ongoing, with various components at different phases of construction. As part of the utility upgrades necessary for the Approved Project, the applicant is requesting excavation and related permits from the City to complete installation of the underground Southern California Edison (“SCE”) electrical utility line in the public right-of-way (“Proposed Project”). The Proposed Project will include the installation of approximately 795 linear feet of underground electrical conduit and two new underground electrical vaults and related vent lines within the South Santa Monica Boulevard right-of-way in the segment generally located between Charleville Boulevard and Wilshire Boulevard. The Proposed Project will also include approximately 1 The Final SEIR and Addenda are available online at www.beverlyhills.org/environmental Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
2 50 linear feet of underground electrical conduit within Charleville Boulevard, north of South Santa Monica Boulevard.

Work for the Proposed Project will be performed over approximately 39 days as follows:
• Days 1 - 12 (9:00 AM to 9:00 PM) in the area from Wilshire Boulevard to Charleville Boulevard o Work involving high noise generating activities, such as saw cutting and potholing, will not be performed past 6:00 PM.
• Days 12 - 19 (9:00 AM to 9:00 PM) on the segment of Charleville Boulevard on the north side of South Santa Monica Boulevard
o Work involving high noise generating activities, such as saw cutting and potholing, will not be performed past 6:00 PM.
• Days 20 - 39 (9:00 PM to 6:00 AM) in and around the intersection of South Santa Monica and Wilshire Boulevard
o Work involving high noise generating activities may occur during these hours Within the 39 days, approximately 4 days will not have any actual construction work as this time period is required for the asphalt to cure and striping of lanes. As a result, there will be a total of 35 active construction days. No construction in the areas fronting the Peninsula Hotel will be undertaken after 9:00 PM or before 9:00 AM to avoid any perceived impact to hotel guests.

Additionally, in the segment of South Santa Monica Boulevard between Lasky Drive and Charleville Boulevard, all saw cutting, asphalt milling, loaded truck operations, hydro-excavation, and paving will be performed exclusively during the City’s permitted construction hours of 8:00 AM to 6:00 PM, excluding weekends and public holidays.

Construction will proceed in segments, with the work in each segment typical of in-street utility work, including potholing (to avoid other utilities in the street), saw cutting a 5 foot wide section of asphalt for the conduit trench, asphalt grinding to remove the 5 feet wide section of roadway, excavation for the 5 foot wide conduit trench (approximately 6-10 feet in depth), excavation of two subterranean vault locations, installation of conduit, and installation of two precast 7’ x 14’ x 8’ concrete utility vaults (one closer the Wilshire Boulevard end of the segment and another closer the Charleville Boulevard end of the segment). The completed trench alignment and vault locations will be backfilled with slurry base installation and then covered with asphalt. Excavated trench material, totaling approximately 2,500 cubic yards and approximately 215 cubic yards of asphalt pavement, will be periodically hauled offsite. The Proposed Project would also involve the import of 1,100 cubic yards of backfill slurry, 68 cubic yards of aggregate base, and 200 cubic yards of asphalt paving material. Hauling of excavated trench material will involve not more than a maximum of 6 dump trucks on any single day. There will be approximately 18 days of hauling of excavated materials. Steel plates will be set over all open excavations at the end of each work day to maintain roadway access and ensure public safety. Flag personnel will be in the corridor to ensure proper traffic flow during construction activities and to ensure continued access to existing driveways, e.g. for guests to the Peninsula Hotel.

A portion of the work required for the conduit at the Wilshire Boulevard crossing at South Santa Monica Boulevard and repaving on Charleville Boulevard will be performed during nighttime hours Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
3 (9:00 PM to 6:00 AM); this nighttime phase encompasses approximately 15 nights and includes potholing, saw cutting, excavation, conduit installation, slurry backfill, base installation, paving, and final striping, with saw cutting and asphalt grinding undertaken at the initial portion of the nighttime work.

Following completion of the underground utility installation, the disturbed portions of the roadway surface will be restored and lanes restriped. The Proposed Project will be completed entirely within previously disturbed areas in the existing roadway. Exhibit 2 provides a work plan prepared by the project contractor describing each day of construction and related equipment as well as the proposed traffic control plans for each work area and phase.

The Proposed Project does not involve the construction of any new buildings, does not increase the allowable floor area of the Approved Project, does not increase the permitted heights of any buildings, and does not increase the intensity of buildings or uses permitted in the Specific Plan area.

The electrical infrastructure connection is necessary to provide electrical service to the Approved Project.

PURPOSE:

This Addendum to the Final SEIR is being prepared pursuant to Section 15164 of the California Environmental Quality Act (CEQA) Guidelines which allows for a lead agency to prepare an addendum to a previously certified EIR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for the preparation of a subsequent EIR have occurred.

Pursuant to CEQA Guidelines Section 15162, no subsequent EIR shall be prepared for the project unless, on the basis of substantial evidence in the light of the whole record, one or more of the following is determined:
(1) Substantial changes are proposed in the project that will require major revisions of the previous EIR due to the involvement of new, significant environmental effects or a substantial increase in the severity of previously identified significant effects; (2) Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or
(3) New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete or the Negative Declaration was adopted, shows any of the following:
(A) The project will have one or more significant effects not discussed in the previous EIR or negative declaration;
Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
4 (B) Significant effects previously examined will be substantially more severe than shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or
(D) Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measures or alternative.

FINDINGS CONCERNING ENVIRONMENTAL IMPACTS OF REVISIONS TO THE PROJECT:
(1) The Approved Project consists of the comprehensive development of the 17.4-acre Project Site, and includes the following:
• New 162 residential unit, 499,706 SF, 32-story, 410’ tall residential building (Santa Monica Residences);
• New 141 residential unit, 424,266 SF, 28-story, 369’ tall residential building (Garden Residences);
• New 37 residential unit and 42 hotel room, 213,966 SF, 11-story, 124’ tall hotel/residential building (Wilshire Building);
• New 127,324 SF structure containing amenities and support areas, including accessory spaces that could be used for staff housing (Promenade); • Replacement of the 37,562 SF, 31’ tall conference center for the Beverly Hilton Hotel; • Replacement of the 72,697 SF, 20’ tall hotel restaurant, retail, 36 hotel room, and support area structure (Beverly Hilton Enhancement); and • 12.7 acres of open space, including an 8-acre botanical garden The Approved Project was reviewed pursuant to the California Environmental Quality Act (Public Resources Code Sections 21000, et seq. (“CEQA”), and the State CEQA Guidelines (California Code of Regulations, Title 14, Sections 15000, et seq.). The City prepared a Final SEIR and, based on the information contained in the SEIR, determined that the Approved Project would result in significant and unavoidable adverse impacts after the implementation of mitigation measures. As a result, the City Council adopted a Statement of Overriding Considerations in conjunction with approval of the Specific Plan.

Based on the analysis contained in the SEIR, the Approved Project would result in the following significant and unavoidable impacts with mitigation:
• Cultural Resources (impacts to historical resources)
• Noise (cumulative constriction-related noise)
Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
5 Based on the analysis contained in the SEIR, the Approved Project was found to result in the following significant impacts that were mitigated to less than significant levels:
• Aesthetics (ambient night-time light levels)
• Air Quality (temporary emissions of criteria air pollutants during construction) • Biological Resources (nesting birds and bat habitats) • Cultural Resources (archaeological resources and human remains) • Energy (long-term operations)
• Geology and Soils (seismic ground shaking)
• Hazards and Hazardous Materials (release of hazardous materials into the environment)
• Hydrology and Water Quality (construction and operational water quality impacts) • Land Use and Planning (consistency with local and regional planning policies) • Noise (construction)
• Public Services (emergency response access)
• Transportation and Traffic (conflict with programs, plans, ordinances, or policies or disrupt local public transit, active transportation, and roadway systems; site access and hazardous traffic conditions; cumulative construction traffic) • Tribal Cultural Resources (impacts to tribal cultural resources resulting from ground disturbing activities during construction)
• Utilities and Service Systems (fire flow facilities)
• Wastewater Treatment (discharge of fats, oils, and grease) The Approved Project was found to result in less than significant impacts or no impacts in the following topic areas:
• Air Quality (consistency with AQMP, temporary localized emissions of criteria air pollutants during construction, long-term emissions of criteria air pollutants during operation, localized CO and TAC emissions)
• Biological Resources (sensitive habitats, riparian habitats, state or federally protected wetlands; conflict with local policies protecting biological resources; conflict with an adopted conservation plan)
• Geology and Soils (earthquake fault rupture)
• Greenhouse Gas (generate GHG emissions or conflict with an applicable plan policy, or regulation adopted for reducing GHG emissions)
• Noise (operational, traffic noise, and construction vibration) • Transportation and Traffic (vehicle miles traveled)
• Utilities and Service Systems (water demand)
The Proposed Project does not change any of the conclusions reached for these topics since it does not result in an increase in floor area, density, hotel rooms, or building height compared to the Approved Project. The Proposed Project would not alter the distribution, location, extent, or density Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
6 of the uses or buildings permitted in the Approved Project and does not alter the approved architectural style or modulation of the buildings. Although the Proposed Project involves installation of an electrical utility line on a street that is not adjacent to the Approved Project site, this location does not affect construction duration or methods, nor does it change operations in a way that would materially change the analysis and impact conclusions in the SEIR and prior addenda (as described below).
(2) On June 8, 2021, the City Council certified the SEIR and approved the Approved Project. In addition, the Final SEIR identified certain mitigation measures that were necessary to mitigate potential impacts of the Approved Project to less than significant levels. The mitigation measures were adopted by the City Council and made binding on the Approved Project (City Council Resolution No. 21-R-13348).
(3) On June 13, 2024, the Planning Commission of the City of Beverly Hills adopted Addendum #1 to the Final SEIR in conjunction with the approval of Resolution No. 2061 approving an amendment to a Conditional Use Permit to re-located temporary construction offices and staging uses related to the Specific Plan buildout to a different site, located at 9900 N. Santa Monica Boulevard.
(4) On October 15, 2024, the Planning Commission adopted Addendum #2 to the Final SEIR in conjunction with the approval of Resolution No. 2072 approving an Administrative Modification of the Specific Plan to allow the installation of a retractable shade canopy structure on the rooftop of the Waldorf Astoria Hotel located at 9850 Wilshire Boulevard. (5) On May 6, 2026, staff prepared Addendum #3 to the Final SEIR in conjunction with a request by the applicant for amendments to the Specific Plan. That application is currently pending review and recommendation by the Planning Commission and final approval by the City Council, and thus Addendum #3 has not yet been adopted. (6) Thereafter, an application for excavation and related permits were submitted (the “Proposed Project” under consideration for this analysis) to the City on July 29, 2026, to allow the installation of the underground electrical utility outlined in the Project Description. (7) Staff analyzed the Proposed Project, along with expert technical analysis prepared by LSA (Exhibits 3 and 4) to determine if any new impacts, or substantial increase in the severity of impacts, would result from the proposed modifications. Pursuant to CEQA Guidelines Section 15162, neither a subsequent nor supplemental EIR is required for the Proposed Project because:
(A) The Approved Project consisted of the comprehensive development of a 17.4-acre site located at 9850, 9876, 9900, and 9988 Wilshire Boulevard, including up to 340 residential condominiums, an Amenity Access Program, and a Promenade (Amenity Area). The Proposed Project intends to install underground electrical utilities on South Santa Monica Boulevard and Charleville Boulevard to serve the Approved Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
7 Project. No new buildings, floor area, additional height, or operational changes are proposed. Since the Proposed Project is limited to utility construction there are no operational impacts to the Approved Project. Additional analysis of the Proposed Project and impact study areas is provided as follows:

Aesthetics. Aesthetic impacts of the Approved Project were screened out pursuant to the provisions of Public Resources Code Section 21099(d) due to the Project Site being in a Transit Priority Area (“TPA”). However, previous environmental documentation analyzed aesthetic impacts based on potential increases to ambient night-time light levels. A mitigation measure was imposed to shield light sources and direct them downward when intended to illuminate walking or working surfaces and focused on the project site to prevent light spillover onto adjacent properties or roadways. The Proposed Project would consist of installing underground electrical utilities during the construction phase of the Approved Project. The Proposed Project would not create any new light sources or result in any changes to project aesthetics. Previously required mitigation measures would still be applicable. Accordingly, the Proposed Project would not result in any new aesthetics impacts, nor would it increase the severity of previously identified significant impacts.

Air Quality. The SEIR for the Approved Project identified construction-related emission impacts resulting from use of heavy-duty construction equipment, fugitive dust mobilized by export of demolition debris and soil export, and the evaporation of VOCs from architectural coatings, which were mitigated to a less than significant level. The Final SEIR’s construction analysis encompassed extensive demolition, mass grading, and building construction over an approximately 50-month period, including 550,000 cubic yards of soil export. The Final SEIR determined that the Approved Project’s unmitigated maximum daily construction-phase NOX emissions would exceed the South Coast Air Quality Management District (SCAQMD) regional threshold of 100 pounds per day, primarily due to haul truck emissions from mass soil export and concurrent operation of heavy-duty demolition and grading equipment. Through implementation of mitigation measures, maximum daily NOX emissions would be reduced to 69 pounds per day, below the regional threshold. Architectural coatings were the primary source of VOC emissions in the Final SEIR analysis.

The Proposed Project involves limited, short-term construction activities in the public right-of-way that are substantially smaller in scale, duration, and intensity than the activities studied in the Final SEIR. The Proposed Project duration is a total of 39 days, of which only 35 would involve active construction activities that would generate emissions, and construction equipment would not all be operating concurrently on any given day. The Proposed Project would involve the export of approximately 2,500 cubic yards of trench material and approximately 215 cubic yards of removed asphalt pavement, as well as import of 1,100 cubic yards of Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
8 backfill slurry, 68 cubic yards of aggregate base, and 200 cubic yards of asphalt paving material. LSA prepared an analysis of the air quality impacts of the Proposed Project using the same methodology as the Final SEIR, with adjustments made for applicable SCAQMD thresholds based on the proximity of the Proposed Project to sensitive receptors as well as the size of the work area for the Proposed Project (Exhibit 3). LSA’s analysis found that the Proposed Project would not exceed shortterm regional construction emissions thresholds for VOCs, NOX, CO, SOX, PM10, or PM2.5, nor would they exceed localized construction emissions thresholds for NOX, CO, PM10, or PM2.5 with previously required mitigation measures. Based on LSA’s analysis, the Proposed Project would not result in a substantial increase in severity of air quality impacts as compared with those disclosed in the Final SEIR. Regional construction emissions and localized impacts associated with the Proposed Project remain below the applicable SCAQMD thresholds.

The Proposed Project would also not result in any additional or more severe operational air quality impacts from mobile source emissions, as the Proposed Project does not involve any new buildings, floor area, height, increase in capacity, or changes to operations. Furthermore, the mitigation measures applicable to the Approved Project would continue to apply to the Proposed Project, thereby further limiting any potential emissions. Accordingly, the Proposed Project would not result in any new air quality impacts, nor would it increase the severity of previously identified significant impacts.

Biological Resources. The SEIR identified potentially significant impacts to locally important wildlife species, specifically nesting birds and roosting bats. The analysis found that certain trees located on the Los Angeles Country Club site would have high potential to support nesting birds and raptors, and the building on the gas station site at 9988 Wilshire Boulevard could also have potential for nesting birds as well as roosting bats. The SEIR imposed mitigation measures requiring demolition, construction, ground disturbance, and vegetation clearing activities in such a way as to avoid protected nesting birds by not initiating these activities during avian breeding and nesting season without a pre-construction survey conducted by a qualified biologist for active bird nests covering the construction footprint plus a buffer of 500 feet. Another mitigation measure was imposed requiring a clearance survey to determine if bats are roosting in the Spanish tile roof of the gas station located at 9988 Wilshire Boulevard. Since construction of the Approved Project has commenced, demolition of the gas station has been completed, and additional demolition and ground disturbance activities have commenced in compliance with all required mitigation measures. No bat roosts were found, and buffers were implemented around identified bird nests on the construction site pursuant to the recommendations of a qualified biologist. The Proposed Project would not result in any new structures or demolition of any other structures that were previously analyzed as part of the Approved Project. Therefore, there are no existing structures that could serve as suitable bat habitat would be Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
9 disturbed. The Proposed Project also does not involve the removal of any trees or vegetation that could serve as suitable bird habitat. Furthermore, mitigation measures requiring nesting bird surveys would still be applicable to prevent impacts to any nesting birds. Accordingly, the Proposed Project would not result in any new impacts to biological resources, nor would it increase the severity of previously identified significant impacts.

Cultural Resources. The SEIR for the Approved Project identified significant and unavoidable impacts to the Beverly Hilton Hotel property, which is a historical resource. Mitigation measures were imposed, and a statement of overriding considerations was adopted. The Proposed Project involves excavation within South Santa Monica Boulevard and Charleville Boulevard, both public rights-ofway that have been previously disturbed through roadway construction, prior utility installations, and ongoing maintenance. The Proposed Project does not involve any additional demolition or otherwise impact the historical resources identified at the Beverly Hilton Hotel property or any other identified historical resources. The Proposed Project would involve subsurface excavation of limited depth in areas that have been previously disturbed. To the extent that the excavation could potentially encounter previously unknown archaeological resources, Mitigation Measure CR-3a, which sets forth requirements in the event of a previously unknown artifact is uncovered during project construction, would still apply. With existing mitigation measures, the Proposed Project would not result in any new impacts on any historical resources, nor would it increase the severity of previously identified significant impacts.

Energy. Energy impacts of the Approved Project were identified in prior environmental documentation and were based on a requirement for permanent grid connections for electricity and natural gas service to power internal and exterior building lighting and heating and cooling systems for long-term operation.

These impacts were mitigated to less than significant levels by requiring compliance with energy conservation requirements of the California Energy Code and California Green Building Standards Code, as well as additional mitigation measures, including Mitigation Measure ENG-1, which requires that the applicant “make necessary alterations to the generation or distribution system as required by SCE.” The Proposed Project is the installation of the electrical infrastructure to connect to the SCE distribution system consistent with this mitigation measure.

The SCE infrastructure connection itself does not increase operational energy demand beyond what was studied in the Final SEIR. Rather, it provides the delivery mechanism for the electrical service already contemplated. The Proposed Project does not involve any building expansion or additional floor area, nor would it introduce more energy intensive land uses as compared to the Approved Project.

Thus, the Proposed Project would have similar energy demands as compared to the Approved Project, since the Proposed Project does not represent a significant change or increase in the size or scale of uses, light fixtures, or other energy Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
10 intensive features. The Approved Project would still be subject to the California Energy Code and Green Building Standards Code requirements, and conditions of approval requiring LEED Gold certification would continue to apply. Therefore, the Proposed Project would not result in any new energy impacts, nor would they increase the severity of previously identified significant impacts.

Geology and Soils. Geology and soils impacts of the Approved Project had to do with seismically induced ground shaking that could damage structures and infrastructure, resulting in loss of property or risk to human safety. The Santa Monica Fault Zone is designated as an Alquist-Priolo Earthquake Fault Zone, and the Proposed Project is not located within 50 feet of this Fault Zone. Both the Approved Project and the Proposed Project would be required to comply with applicable provisions of the Beverly Hills Municipal Code (“BHMC”) and California Building Code. With adherence to the applicable code requirements and mitigation measures, the Proposed Project would not result in any new geology or soils impacts, nor would it increase the severity of previously identified significant impacts.

Greenhouse Has Emissions. Construction and operation of the Approved Project would generate temporary and long-term Greenhouse Gas (“GHG”) emissions. The Final SEIR determined that the Approved Project’s total GHG emissions would result in an increase of 2,564.8 MT CO2e per year as compared to existing conditions, which would not exceed the SCAQMD brightline threshold of 3,000 MT CO2e per year, nor would it exceed the locally applicable, project-specific efficiency threshold of 3.2 MT CO2e per service person per year. The Final SEIR determined that the Approved Project’s construction emissions would be about 587 MT CO2e per year. As a result, the Final SEIR concluded that the Approved Project’s GHG emissions would be less than significant and did not require GHG mitigation measures. The Final EIR also cited numerous sustainability features, including commitments to achieve LEED and WELL certification, as well as energy- and water-efficient building design features that reduce long-term operational energy use and GHG emissions.

The Proposed Project does not involve any changes to the Approved Project operations, and all conditions of approval relating to sustainability are applicable.

The Proposed Project would generate temporary construction-related GHG emissions from the operation of construction equipment during conduit and vault installation as well as from worker and building supply vendor vehicles during the construction period. Based on the air quality and GHG analysis provided by LSA, the Proposed Project would generate approximately 84.1 MT CO2e during construction, which when amortized over a 30-year project life, would equal approximately 2.8 MT CO2e per year. When combined with the GHG emissions modeled for the Approved Project, the Proposed Project would not exceed the SCAQMD recommended brightline threshold of 3,000 MT CO2e per year, nor would Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
11 it exceed the locally appliable, project-specific efficiency threshold of 3.2 MT CO2e per service person per year. Therefore, the Proposed Project would not result in any new GHG emissions impacts, nor would it increase the severity of previously identified significant impacts.

Hazards and Hazardous Materials. Hazards and hazardous materials impacts of the Approved Project were focused on the removal of the gas station located at 9988 Wilshire Boulevard, which had gas pumps and a canopy structure, three underground storage tanks, and a convenience store, as well as other buildings at the Approved Project Site which may have contained asbestos, lead-based paints, and/or PCB’s that would be demolished as part of the Approved Project. Since construction of the Approved Project commenced, all structures at the gas station site, including underground storage tanks, have been removed in compliance with all applicable mitigation measures. Other building demolition at the Approved Project site has also been completed in compliance with all applicable mitigation measures.

The Proposed Project involves limited excavation within the South Santa Monica Boulevard and Charleville Boulevard public rights-of-way. These corridors have been previously disturbed and are not located in close proximity to any known sites that are subject to active environmental investigations or ongoing remediation. As discussed in the Final SEIR Section 4.6, Hazards and Hazardous Materials, “[t]he management of hazardous materials and hazardous wastes is regulated at the federal, state, and local levels through programs administered by the U.S.

Environmental Protection Agency; agencies within the California Environmental Protection Agency, such as the Department of Toxic Substances Control and the State Water Resources Control Board; federal and state occupational safety agencies, such as the Occupational Safety and Health Administration and the Division of Occupational safety and Health; and locally by the Los Angeles County Fire Department Health and Hazardous Materials Division. If contaminated soils or other hazardous materials are encountered during excavation, the applicant would be required to comply with all applicable local, state, and federal regulations for handling and disposal of such materials.” Additionally, existing underground utilities beneath the roadways would be identified through utility locating procedures (potholing) prior to construction to avoid accidental damage.

Accordingly, with compliance with existing regulations relating to the handling of hazardous materials, the Proposed Project would not result in any new impacts related to hazards or hazardous materials, nor would it increase the severity of previously identified significant impacts.

Hydrology and Water Quality. Water quality impacts of the Approved Project were identified in prior environmental documentation and were based on demolition and construction related water quality impacts as well as parking lot/garage generated pollutants and runoff from landscaped areas. Mitigation measures were imposed Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
12 requiring preparation of a Notice of Intent and Stormwater Pollution Prevention Plan in accordance with State requirements, as well as submittal of a Standard Urban Stormwater Mitigation Plan in accordance with Los Angeles County requirements.

With these mitigation measures, impacts were found to be less than significant. The Proposed Project involves limited excavation within the South Santa Monica Boulevard and Charleville Boulevard public rights-of-way, which would temporarily expose soils and generate sediment-laden runoff if not properly managed. The Proposed Project would be subject to the same mitigation measures as the Approved Project, including Hydro-1 and Hydro-2, and would be required to implement the appropriate Best Management Practices during construction to prevent sediment and other pollutants from entering the storm drain system.

Accordingly, the Proposed Project would not result in any new impacts to hydrology or water quality, nor would it increase the severity of previously identified significant impacts.

Land Use and Planning. The Approved Project was found to be consistent with applicable local and regional planning policies, regulations, and standards with implementation of various mitigation measures throughout the Final SEIR, and as a result, impacts were found to be less than significant. The Proposed Project is required for the implementation of the Specific Plan and does not result in any increase in floor area, density, hotel rooms, or building height compared to the Approved Project. The Proposed Project would not alter the distribution, location, extent, or density of the uses or buildings permitted in the Specific Plan and does not alter the approved architectural style or modulation of the buildings. Therefore, it is consistent with the applicable development standards.

The Proposed Project involves typical utility installation in public rights-of-way to provide adequate electrical service the One Beverly Hills project. Section 5.2 of the Specific Plan identifies General Plan goals and policies that would be advanced by the Approved Project. The Proposed would not conflict with any of the goals and policies listed therein, and would further support the following policies from the General Plan:
• CON 18.1 New Development Requirements:Require that new development is approved contingent upon the ability to be served with adequate electrical facilities and service.
• CON 18.2 Adequate Facilities: Work with Southern California Edison and the City’s Department of Public Works and Transportation to ensure that adequate electrical facilities are available to meet the demand of existing and future development, and to encourage conservation.
• CON 18.3 Underground Utilities: Continue to provide for the undergrounding of new and existing electrical distribution lines unless it is Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
13 determined not to be economically or practically feasible in a particular location as a result of significant environmental or other constraints.

Explore innovative funding sources for undergrounding utilities.

The Proposed Project would be consistent with the above General Plan policies because it consists of enhancing electrical utilities to provide adequate service for new development. The utilities would be fully underground, and the full cost of the enhancements would be borne by the applicant, with no funding required by the City.

Approval of the Proposed Project would be consistent with local planning policies, regulations, and standards, and all mitigation measures required in the Final SEIR for the Approved Project would continue to apply to the Proposed Project.

Accordingly, the Proposed Project would not result in any new land use and planning impacts, nor would it increase the severity of previously identified significant impacts.

Noise. Potentially significant noise impacts related to Approved Project construction and significant and unavoidable noise impacts related to cumulative construction noise were identified in the Final SEIR. Specifically, the impacts resulted from exceedance of 5 dBA above ambient noise levels before 8:00 a.m. or after 6:00 p.m. With implementation of mitigation measures, impacts related to Approved Project construction were reduced to less than significant, however cumulative construction noise impacts remained significant and unavoidable. A statement of overriding considerations was adopted by the City Council in its approval of the Approved Project.

With respect to construction noise impacts, the Final SEIR analyzed whether construction noise occurring at the One Beverly Hills project site would result in a noise increase of 5 dBA or more outside the hours permitted by the City’s Noise Ordinance, or would increase noise by 5 dBA or more during daytime hours at a school, hospital, church, or institute of learning. The Final SEIR concluded that the Approved Project would generate construction noise levels in excess of 5 dBA above ambient noise levels at El Rodeo school during simultaneous occurrence of the demolition, grading, and building construction phases and during simultaneous occurrence of the building construction, architectural coating, and paving phases.

Similarly, the Final SEIR concluded that construction activities for the Approved Project would generate noise levels in excess of 5 dBA above ambient noise levels outside the hours permitted by the City’s Noise Ordinance for residences to the north of the One Beverly Hills project site. However, the Final SEIR concluded that these impacts would be less than significant through compliance with applicable provisions of Mitigation Measure NOISE-1, which includes various requirements such as avoiding simultaneous construction phases, the use of mufflers and sound enclosures, and placement of heavy equipment to direct noise away from sensitive Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
14 receptors. The Final SEIR also found that construction traffic from the Approved Project would not generate noise in excess of 5 dBA above ambient noise levels, and therefore off-site construction noise impacts would be less than significant.’ LSA prepared an analysis of the potential noise and vibration impacts of the Proposed Project (Exhibit 4). Based on this analysis, construction-related traffic would increase noise levels by up to 0.7 dBA above ambient noise levels, which would not exceed the 5 dBA noise threshold. LSA also modeled the potential noise impacts of construction activities, including the use of various types of construction equipment based on information provided by the applicant and their contractor. Based on the Project Description, the work that requires the highest noise-generating equipment, such as saw cutting and potholing, would occur on weekdays during the hours of 9:00 AM and 6:00 PM. Other activities that would occur outside of those hours would result in an increase in ambient noise levels by up to 8.8 dBA between 6:00 PM and 9:00 PM and up to 17.8 dBA between 9:00 PM and 6:00 AM without the implementation of mitigation measures. Since activities during these hours would exceed the City’s 5 dBA threshold, unmitigated noise from the Proposed Project during these periods would be potentially significant.

However, with the implementation of mitigation measure NOISE-1, which was already adopted by the Final SEIR, noise would be reduced to within 5 dBA above ambient noise levels. Therefore, noise generated from construction of the Proposed Project outside of the City’s permitted construction hours would be less than significant with implementation of mitigation measure NOISE-1.

With respect to operational off-site traffic noise impacts, the Proposed Project would not introduce any new land uses or increase in the density or intensity of previously approved land uses. The Proposed Project involves installation of underground electrical utilities to serve the Approved Project and vehicular traffic associated with the Proposed Project would be temporary in nature. Thus, the Proposed Project would not generate substantially increased long-term operational vehicular traffic and would not create any new off-site traffic noise impacts.

The Final SEIR also evaluated construction vibration associated with the Approved Project’s use of construction equipment including jackhammers, loaded trucks, and bulldozers and determined that transient vibration levels would not exceed the thresholds for daytime human annoyance or structural damage to historic buildings or residential structures from occasional pass-bys of construction equipment. LSA provided an analysis of construction vibration for the Proposed Project, assessing whether vibration levels would exceed thresholds for receptors near the Proposed Project work area, including the commercial businesses, the nearest residential building (Rosewood Residences), the Peninsula Hotel, and single-family residences north of Wilshire boulevard. The analysis found that the vibration levels would not exceed the 0.500 in/sec PPV transient vibration damage threshold, nor would they exceed the 0.240 in/sec PPV transient vibration Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
15 annoyance threshold for any of these receptors. With respect to nighttime vibrations, the nearby commercial receptors would not be in operation during night work and the Project Description indicates that there would be no nighttime construction activities near the Peninsula Hotel or the Rosewood Residences.

Therefore, the night-time vibration annoyance threshold would not be applicable.

All noise-related mitigation measures would continue to apply to the Proposed Project, further reducing the potential for construction noise impacts. Therefore, the Proposed Project would not result in any new noise impacts, nor would it increase the severity of previously identified significant impacts.

Public Services. Public services impacts of the Approved Project were identified in prior environmental documentation and were based on statements from the Beverly Hills Fire Department that the proposed traffic signal at the intersection of Merv Griffin Way and Santa Monica Boulevard could potentially slow emergency response times and inhibit access to the site, but that impacts would be less than significant with implementation of a mitigation measure requiring certain technical changes to the proposed traffic signal. The Proposed Project does not involve any changes to the proposed traffic signal contemplated in the Approved Project, and the mitigation measure would continue to apply. The Proposed Project would involve temporary construction activities within the South Santa Monica Boulevard and Charleville Boulevard public rights-of-way that would require temporary lane closures. However, the Construction Traffic management Plan required by mitigation measure TRAF-5 includes provisions for maintaining emergency access and coordinating with emergency service providers. Accordingly, the Proposed Project would not result in any new impacts to public services, nor would they increase the severity of previously identified significant impacts.

Transportation and Traffic. Transportation and traffic impacts of the Approved Project were determined to be less than significant with mitigation. The Proposed Project involves temporary construction activities to install underground electrical utilities and would not have any effect on the density or intensity of the land uses in the Approved Project. Thus, the Proposed Project would not generate any additional operational traffic than was already analyzed as part of the Final SEIR for the Approved Project.

The Final SEIR analyzed construction traffic impacts including haul truck traffic, delivery and staging of materials, worker traffic, and temporary lane and sidewalk closures. South Santa Monica Boulevard has two travel lanes in each direction and is classified as a Minor Arterial between the western City limit and Wilshire Boulevard where the Proposed Project would occur. The Proposed Project would involve temporary construction activities within the South Santa Monica Boulevard and Charleville Boulevard public rights-of-way, requiring temporary lane closures during various periods of active work operations. These closures would be Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
16 temporary and limited to the active work zone, and traffic control measures would be implemented to maintain traffic flow and pedestrian access. The Proposed Project would comply with applicable mitigation measures, including TRAF-5, which requires preparation of a Construction Traffic Management Plan. The Proposed Project would occur over a 39-day period using a maximum crew of 36 personnel on peak days. This amounts to approximately 2% of the Approved Project’s peak daily workforce estimate of 2,400 personnel.

All mitigation measures from the Approved Project would continue to apply to the Proposed Project. Accordingly, the Proposed Project would not result in any new transportation or traffic impacts, nor would it increase the severity of previously identified significant impacts.

Tribal Cultural Resources. Impacts to tribal cultural resources for the Approved Project were determined to be less than significant with mitigation. The Final SEIR required monitoring by two consulted tribal organizations during construction that would involve ground disturbing activities such as grading and surface excavation, which would have the potential to unearth or adversely affect previously unidentified significant tribal cultural resources. The Proposed Project involves excavation within previously graded and disturbed roadways. Nonetheless, all mitigation measures from the Approved Project would continue to apply to the Proposed Project. Accordingly, the Proposed Project would not result in any new impacts tribal cultural resources, nor would it increase the severity of previously identified significant impacts.

Utilities and Service Systems. Impacts to utilities and service systems for the Approved Project were determined to be less than significant with mitigation. The Final SEIR analyzed the impact of additional population, building height, and development area to the Approved Project site as compared to existing conditions, as well as the impact of increased water demand. Mitigation measures were imposed requiring review of fire flow requirements and a hydraulic analysis to determine the need for upgrades to City water mains.

The Proposed Project involves installation of SCE electrical distribution infrastructure in connection with the implementation of the Approved Project. As part of the previous environmental documentation, including the Final SEIR, electrical distribution system upgrades were contemplated by mitigation measure ENG-1, which requires that the applicant “make necessary alterations to the generation or distribution system as required by SCE.” The Proposed Project would occur within the South Santa Monica Boulevard and Charleville Boulevard public rights-of-way, where existing underground utilities may include water mains, sewer lines, gas lines, and telecommunications infrastructure. Existing underground utilities beneath the roadways would be identified through potholing prior to construction to avoid accidental damage. The Proposed Project does not increase Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
17 water demand, affect fire flow capacity, or otherwise alter the demand for utility services associated with the Approved Project.

Additionally, wastewater treatment impacts of the Approved Project were identified in prior environmental documentation and were based on the potential for the restaurant use in the Approved Project to generate heavier discharge of fats, oils, and grease, which was considered a potentially significant impact that was mitigated to less than significant. The Proposed Project involves construction of underground electrical utilities and would not increase the total floor area of restaurants or other uses that would generate fats, oils, or grease.

Accordingly, the Proposed Project would not result in any new impacts to utilities and service systems, nor would it increase the severity of previously identified significant impacts.
(B) There are no changes with respect to the circumstances under which the project is undertaken that will require major revisions of the previous EIR due to the involvement of new significant environmental effects or a substantial increase in the severity of a previously identified impact. Since approval of the Approved Project, the City of Beverly Hills has not approved any new significant development projects within the vicinity of the Project site. Further, the Proposed Project will not result in any cumulatively considerable change in the Approved Project impacts. Accordingly, no cumulative impacts from the construction and/or operation of the Proposed Project are anticipated. Consequently, the circumstances under which the Proposed Project would be undertaken have not changed when compared to the circumstances in place during approval of the Approved Project.

Staff has identified no new information of substantial importance to suggest that (A) The project will have one or more significant effects not discussed in the previous EIR or negative declaration; (B) Significant effects previously examined will be substantially more severe than shown in the previous EIR; (C) Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or (D) Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measures or alternative.

All mitigation measures adopted in conjunction with the Approved Project continue to be imposed on the Proposed Project.
(8) Therefore, pursuant to CEQA Guidelines Section 15164, the City has prepared this Addendum #4 to the Final SEIR, which documents that the Proposed Project would not result Addendum #4 to the Final Supplemental Environmental Impact Report One Beverly Hills Overlay Specific Plan Project
18 in any of the conditions described in Section 15162, including that the changes would not result in new, significant environmental effects or a substantial increase in the severity of previously identified significant effects.

FROM: Alyssa Barnett, Senior Air Quality Specialist
Cara Cunningham, Associate
SUBJECT: Air Quality and Greenhouse Gas Impact Analysis for the One Beverly Hills Project – Underground Electrical Infrastructure Extension (LSA Project No. 20263059)

INTRODUCTION
The One Beverly Hills Overlay Specific Plan Project (project) was evaluated by the City of Beverly Hills in the One Beverly Hills Overlay Specific Plan Final Supplemental Environmental Impact Report (SEIR). 1 This Air Quality and Greenhouse Gas (GHG) Technical Memorandum evaluates whether construction of off-site underground electrical infrastructure improvements would alter the air quality and GHG impact conclusions presented in the SEIR. This analysis was prepared using methods and assumptions recommended in the air quality impact assessment guidelines of the South Coast Air Quality Management District (SCAQMD) in its CEQA Air Quality Handbook (1993)2 and associated updates.

PROJECT LOCATION
The off-site improvement area is located within the existing public roadway right-of-way on South Santa Monica Boulevard, from Charleville Boulevard to approximately 20 linear feet east of the Wilshire Boulevard intersection in Beverly Hills, California. Figure 1 shows the off-site improvement location (all figures are provided in Attachment A).

PROJECT DESCRIPTION
The proposed off-site improvement project consists of extension of the underground electrical infrastructure within existing public roadway rights-of-way, including the construction of underground conduit systems, utility vaults, vent lines, and associated street restoration 1 City of Beverly Hills. 2021. One Beverly Hills Overlay Specific Plan Final Supplemental Environmental Impact Report. 2 South Coast Air Quality Management District (SCAQMD). 1993.

Construction activities would occur primarily along South Santa Monica Boulevard, the Wilshire Boulevard crossing, and Charleville Boulevard. Figure 2 shows the off-site improvement construction boundary.

The work would be completed over an approximately 39-day construction period and would occur entirely within previously disturbed urban roadway corridors. Major construction activities include utility potholing, saw cutting, asphalt milling and removal, trench excavation, installation of underground electrical conduits, construction and placement of precast electrical vaults, installation of vent line conduits, slurry backfilling, aggregate base placement, asphalt pavement restoration, and final pavement striping. Temporary traffic control measures would be implemented throughout construction, with steel trench plates installed at the end of each workday to maintain vehicular access where excavations remain open.

Construction would begin with utility potholing and conflict identification using hydro-vacuum excavation equipment, followed by saw cutting and asphalt milling of existing pavement surfaces.

Excavation activities would include the removal of approximately 2,500 cubic yards of trench material and approximately 215 cubic yards of asphalt pavement. Excavations would support the installation of approximately 795 linear feet of mainline electrical conduit within South Santa Monica Boulevard, associated vent line conduits, and two underground electrical vault structures.

Approximately, 50 linear feet of conduit would be installed in Charleville Boulevard north of South Santa Monica Boulevard.

Vault construction would include excavation, shoring installation, placement of precast concrete vaults using hydraulic cranes, conduit connections, and slurry backfill. Mainline conduit installation would occur in multiple segments along South Santa Monica Boulevard, Charleville Boulevard, and the Wilshire Boulevard crossing. Vent line conduit installations would be constructed adjacent to both vault locations.

Backfill operations would consist primarily of controlled low-strength material (CLSM) slurry placement, totaling approximately 1,100 cubic yards. Following utility installation, trench sections would be restored using crushed miscellaneous base and asphalt pavement. Approximately 68 cubic yards of aggregate base and 200 cubic yards of asphalt paving material would be imported and placed during roadway restoration. Temporary pavement markings would be installed following paving operations, with final lane striping completed after the required asphalt curing period.

Construction would require crews ranging from approximately 14 to 36 personnel per day, depending on the phase of work. Equipment anticipated during various phases of construction includes hydraulic excavators, wheel loaders, hydro-vacuum excavation trucks, asphalt milling machines, dump trucks, concrete mixer trucks, cranes, asphalt paving equipment, rollers, sweepers, water trucks, and pavement striping equipment.

Temporary impacts associated with construction may include traffic lane closures and detours, construction-generated fugitive dust emissions, equipment exhaust emissions, temporary disruption of roadway circulation, hauling of excavated materials, delivery of construction materials, and shortterm visual effects associated with construction equipment and traffic control devices. Construction activities would occur within developed urban transportation corridors and would not introduce new LSA
8/6/26 «P:\2026\20263059-One Beverly Hills\Product\AQ\One Beverly Hills AQ GHG Analysis.docx» 3 permanent above-ground structures beyond the standard utility access features associated with underground electrical facilities.

Upon completion, the off-site improvements would provide upgraded underground electrical infrastructure intended to improve utility reliability and service capacity.

EXISTING SENSITIVE RECEPTORS IN THE PROJECT AREA
Sensitive receptors are defined as populations that are particularly susceptible to health effects due to exposure to an air contaminant, including schools, playgrounds, childcare centers, long-term healthcare facilities, rehabilitation centers, convalescent centers, hospitals, retirement homes, and residences.3

The off-site improvement area is bounded mostly by commercial land use north and south of the project site perimeter; and residential land use at the corner of South Santa Monica Boulevard and Charleville Boulevard (Rosewood Residences) and northwest of the project site, across North Santa Monica Boulevard and southeast of the project site. Since the off-site utility improvements extend approximately 795 linear feet, the nearest sensitive receptor varies throughout the construction corridor. Adjacentsensitive receptorsinclude the Rosewood Residences as well as nearby residential uses. The Rosewood Residence is the closest sensitive receptor, located approximately 46.6 feet (14.1 meters) from the nearest construction activities. Additional residential uses are located adjacent to other portions of the construction at greater distances.

ENVIRONMENTAL SETTING
This section provides background information on air quality and GHG emissions.

Air Quality
Air quality is primarily a function of local climate, local sources of air pollution, and regional pollution transport. The amount of a given pollutant in the atmosphere is determined by the amount of the pollutant released and the atmosphere’s ability to transport and dilute the pollutant. The major determinants of transport and dilution are wind, atmospheric stability, terrain, and, for photochemical pollutants, sunshine.

A region’s topographic features have a direct correlation with air pollution flow and therefore are used to determine the boundary of air basins. The proposed project is in Los Angeles County and within the South Coast Air Basin (Basin), and it is therefore subject to the jurisdiction of, and regulations promulgated by, the SCAQMD.

The Basin comprises approximately 10,000 square miles and covers all of Orange County and the urban parts of Los Angeles, Riverside, and San Bernardino counties. The Basin is on a coastal plain 3 SCAQMD. 2005. Guidance Document for Addressing Air Quality Issues in General Plans and Local Planning.

May. Website: http://www.aqmd.gov/docs/default-source/planning/air-quality-guidance/completeguidance-document.pdf?sfvrsn=4 (accessed August 2026).

LSA
8/6/26 «P:\2026\20263059-One Beverly Hills\Product\AQ\One Beverly Hills AQ GHG Analysis.docx» 4 with connecting broad valleys and low hills to the east. Regionally, the Basin is bounded by the Pacific Ocean to the southwest and high mountains to the east, forming the inland perimeter.

Both the State and federal governments have established health-based ambient air quality standards for criteria air pollutants: carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), lead, and suspended particulate matter. In addition, the State has set standards for sulfates, hydrogen sulfide, vinyl chloride, and visibility-reducing particles. These standards are designed to protect the health and welfare of the populace with a reasonable margin of safety. Two criteria pollutants, O3 and NO2, are considered regional pollutants because they (or their precursors) affect air quality on a regional scale. Pollutants such as CO, SO2, and lead are considered local pollutants that tend to accumulate in the air locally.

Data collected at permanent monitoring stations are used by the United States Environmental Protection Agency (USEPA) to identify regions as attainment or nonattainment depending on whether the regions meet the requirements stated in the applicable National Ambient Air Quality Standards (NAAQS). At the state level, the California Air Resources Board (CARB) is required to designate areas of the State as attainment, nonattainment, or unclassified for all State standards.

The Basin is designated as nonattainment for the federal standards for O3 and particulate matter less than 2.5 microns in diameter (PM2.5) and nonattainment for the State standards for O3, particulate matter less than 10 microns in diameter (PM10), and PM2.5.

Greenhouse Gases
GHGs are present in the atmosphere naturally, are released by natural sources, or form from secondary reactions taking place in the atmosphere. Over the last 200 years, humans have caused substantial quantities of GHGs to be released into the atmosphere. These extra emissions are increasing GHG concentrations in the atmosphere and enhancing the natural greenhouse effect, which is believed to be causing global warming. Although manmade GHGs include naturally occurring GHGs (e.g., carbon dioxide [CO2], methane [CH4], and nitrous oxide [N2O]), some gases (e.g., hydrofluorocarbons [HFCs], perfluorocarbons [PFCs], nitrogen trifluoride [NF3], and sulfur hexafluoride [SF6]) are completely new to the atmosphere.

Certain gases (e.g., water vapor) are short-lived in the atmosphere. Others remain in the atmosphere for significant periods of time, contributing to climate change in the long term. Water vapor is excluded from the list of GHGs above because it is short-lived in the atmosphere and its atmospheric concentrations are largely determined by natural processes (e.g., oceanic evaporation).

These gases vary considerably in terms of global warming potential (GWP), which is a concept developed to compare the ability of each GHG to trap heat in the atmosphere relative to another gas. The GWP is based on several factors, including the relative effectiveness of a gas in absorbing infrared radiation and the length of time that the gas remains in the atmosphere (i.e., atmospheric lifetime). The GWP of each gas is measured relative to CO2, the most abundant GHG; the definition of GWP for a particular GHG is the ratio of heat trapped by one unit mass of the GHG to the ratio of heat trapped by one unit mass of CO2 over a specified time period. GHG emissions are typically measured in terms of pounds or tons of CO2 equivalents (CO2e).

SUMMARY OF SEIR FINDINGS
As noted previously, an SEIR (State Clearinghouse No. 2020090048) was prepared for the One Beverly Hills Overlay Specific Plan Project and was certified by the City in 2021. The findings from the air quality and GHG analysis in the SEIR, specifically as they relate to construction impacts, are summarized below.

Air Quality
The SEIR found that construction activities related to buildout of the One Beverly Hills Overlay Specific Plan Project would generate emissions exceeding the SCAQMD regional threshold for maximum daily NOX emissions, resulting in a cumulatively considerable net increase of NOX and exposure of sensitive receptors to substantial pollutant concentrations. The SEIR found that construction-related impacts would be significant, and implementation of Mitigation Measures (MMs) AQ-1 through MM-AQ-17 would be required to reduce impacts to a less than significant level.

A list of these measures can be found in Attachment B of this memorandum.

Greenhouse Gas
The SEIR concluded that the construction GHG emissions from buildout of the One Beverly Hills Overlay Specific Plan Project would be less than significant and did not require GHG mitigation measures.

METHODOLOGY
This memorandum quantifies construction-related criteria pollutant and GHG emissions associated with the installation of the underground electrical infrastructure. The addition of the off-site improvement project would not result in new operational land uses, building energy use, area sources, or other ongoing emission sources. Accordingly, operational emissions are not evaluated in this analysis.

The California Emissions Estimator Model (CalEEMod) Version 2022.1 computer program was used to calculate emissions from construction of the off-site improvement project. CalEEMod is a statewide land use emissions web model designed to provide a uniform platform for government agencies, land use planners, and environmental professionals to quantify potential criteria pollutants and GHGs associated with both construction and operation of a variety of land use projects. The model quantifies direct emissions from construction and operations (including vehicle use), as well as indirect emissions, such as GHG emissions from energy use, solid waste disposal, vegetation planting and/or removal, and water use for land use developments and linear projects. Default data (emission factors, trip lengths, meteorology, source inventory, etc.) have been provided by the various California air districts to account for local requirements and conditions.

Construction of the proposed off-site improvements would include utility potholing, saw cutting, asphalt milling and removal, trench excavation, conduit and precast vault installation, slurry backfill, aggregate base placement, asphalt restoration, pavement striping, and associated site restoration.

Construction is anticipated to occur over approximately 39 working days. Construction activities LSA
8/6/26 «P:\2026\20263059-One Beverly Hills\Product\AQ\One Beverly Hills AQ GHG Analysis.docx» 6 would generally include both daytime and nighttime work, with work progressing by construction segment in accordance with the off-site improvement project’s Traffic Control Plan (TCP).

The TCP divides construction into eight planning areas, each representing a separate work area with unique construction activities, equipment requirements, workforce, and material handling assumptions. Rather than modeling off-site improvements as a single construction phase, each planning area was modeled separately in CalEEMod to reflect the phased nature of the proposed improvements and the varying daily construction activities.

The off-site improvements were modeled using the Linear Road Construction land use category.

Construction assumptions were developed using applicant-provided information, which identifies the anticipated daily construction activities, equipment, workforce, and material handling requirements for each construction segment. Specific construction equipment includes excavators, rubber-tired loaders, hydro-vac trucks, cranes, skid steers, asphalt milling equipment, paving equipment, rollers, striping equipment, and sweepers. A list of the modeled construction fleet is available in Attachment C.

Construction would require the export of approximately 2,500 cubic yards of excavated trench material and 215 cubic yards of asphalt pavement for export. Approximately 1,100 cubic yards of CLSM would be imported for trench backfill, along with approximately 68 cubic yards of aggregate base and 200 cubic yards of asphalt paving material. A 20-mile one-way haul distance was conservatively assumed for the transport of exported and imported materials. This analysis assumes the use of Average Tier construction equipment and that the proposed off-site improvements would comply with SCAQMD dust control regulations (Rule 403).

Since certain construction activities and equipment are not explicitly represented in CalEEMod, specific construction activities and equipment were translated into the most representative CalEEMod construction phases and equipment categories. Similarly, the workforce, vendor deliveries, material hauling quantities, and construction schedule were incorporated into the model to reasonably represent the anticipated construction activities. CalEEMod output data are included in Attachment C.

THRESHOLDS OF SIGNIFICANCE
Air Quality Thresholds
The State CEQA Guidelines indicate that a project would normally have a significant adverse air quality impact if project-generated pollutant emissions would do any of the following:
• Conflict with or obstruct implementation of the applicable air quality plan; • Result in a cumulatively considerable net increase of any criteria pollutant for which the project is nonattainment under applicable federal or State ambient air quality standards; • Expose sensitive receptors to substantial pollutant concentrations; or • Result in other emissions (such as those leading to odors) affecting a substantial number of people.

LSA
8/6/26 «P:\2026\20263059-One Beverly Hills\Product\AQ\One Beverly Hills AQ GHG Analysis.docx» 7 Certain air districts (e.g., SCAQMD) have created guidelines and requirements to conduct air quality analysis. The SCAQMD’s current guidelines, the CEQA Air Quality Handbook4 with associated updates, were followed in this assessment of air quality impacts for the proposed project.

Regional Criteria Pollutant Thresholds
SCAQMD has established daily emission thresholds for construction of proposed projects. The emission thresholds were established based on the attainment status of the air basins within the SCAQMD with regard to air quality standards for specific criteria pollutants. Because the concentration standards were set at a level that protects public health with an adequate margin of safety, these emission thresholds are regarded as conservative and would overstate an individual project’s contribution to health risks. Table A lists the CEQA significance thresholds for construction emissions established for the SCAQMD.

SOX = sulfur oxides
VOCs = volatile organic compounds
Projects in the Basin with construction-related emissions that exceed any of their respective emission thresholds would be considered significant under SCAQMD guidelines. These thresholds, which SCAQMD developed and that apply throughout the Basin, apply as both project and cumulative thresholds. If a project exceeds these standards, it is considered to have a project-specific and cumulative impact.

Because of the conservative nature of the thresholds and the basin-wide context of individual project emissions, there is no known direct correlation between a single project and localized air quality-related health effects. One individual project that generates emissions exceeding a threshold does not necessarily result in adverse health effects for residents in the project vicinity. This condition is especially true when the criteria pollutants exceeding thresholds are those with regional effects, such as ozone precursors like nitrogen oxides (NOX) and volatile organic compounds (VOCs).

Further, by its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size to, by itself, result in nonattainment of ambient air quality standards. Instead, a project’s individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a project’s contribution to the cumulative impact is considerable, then the project’s impact on air 4 SCAQMD. 1993. CEQA Air Quality Handbook (currently under revision).

In developing thresholds of significance for air pollutants, the air districts have considered the emission levels for which a project’s individual emissions would be cumulatively considerable. If a project exceeds the identified significance thresholds, its emissions would be cumulatively considerable, resulting in significant adverse air quality impacts to the region’s existing air quality conditions.

Localized Criteria Pollutant Thresholds
The SCAQMD published its Final Localized Significance Threshold Methodology in July 2008, recommending that all air quality analyses include an assessment of air quality impacts to nearby sensitive receptors.5 This guidance was used to analyze potential localized air quality impacts associated with construction of the proposed project. Localized significance thresholds (LSTs) are developed based on the size or total area of the emission source, the ambient air quality in the Source Receptor Area (SRA), and the distance to the project. Sensitive receptors include residences, schools, hospitals, and similar uses that are sensitive to adverse air quality.

LSTs are based on the ambient concentrations of that pollutant within the project’s SRA and the distance to the nearest sensitive receptor. For the proposed project, the appropriate SRA for the LST is the Northwest Coastal Los Angeles County area (SRA 2).

As previously stated, the nearest sensitive receptor varies depending on the active construction area.

The Residences at the corner of Charleville Boulevard and South Santa Monica Boulevard represent the closest sensitive receptor, located approximately 46.6 feet (14.1 meters) south of the nearest construction activities. Since the SCAQMD LST screening tables are available for receptor distances of 25, 50, 100, 200, and 500 meters and allow use of the 25-meter screening distance where receptors are located with 25 meters of the emissions source, a 25-meter receptor distance was used for this analysis.

Construction activities were evaluated using the 1-acre disturbance thresholds, consistent with the maximum daily disturbance area associated with each construction segment. It should be noted that the highest localized emissions are anticipated during construction of Area 1, which is also the segment located closest to the nearest sensitive receptor. This construction segment represents the conservative worst-case scenario for the LST analysis. If localized emissions associated with Area 1 are below the applicable SCAQMD LSTs, localized emissions associated with the remaining construction segments, which would generate lower emissions and/or occur farther from nearby sensitive receptors, would also be below the applicable thresholds. Table B lists the emissions thresholds that apply during project construction.

Greenhouse Gas Thresholds
Appendix G of the State CEQA Guidelines includes significance thresholds for GHG emissions. A project would normally have a significant effect on the environment if it would do either of the following:
• Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment
• Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs
To provide guidance to local lead agencies on determining significance for GHG emissions in their CEQA documents, SCAQMD has convened a GHG CEQA Significance Threshold Working Group (Working Group). Based on the last Working Group meeting held in September 2010 (Meeting No. 15), SCAQMD proposed to adopt a tiered approach for evaluating GHG emissions for development projects where SCAQMD is not the lead agency:
• Tier 1—Exemptions: If a project is exempt from CEQA, project-level and cumulative GHG emissions are less than significant.
• Tier 2—Consistency with a Locally Adopted GHG Reduction Plan: If the project complies with a GHG emissions reduction plan or mitigation program that avoids or substantially reduces GHG emissions in the project’s geographic area (i.e., city or county), project-level and cumulative GHG emissions are less than significant.
• Tier 3—Numerical Screening Threshold: If GHG emissions are less than the numerical screeninglevel threshold, project-level and cumulative GHG emissions are less than significant. For nonstationary source land use types, the SCAQMD applies a “bright-line” screening-level threshold of 3,000 MT of CO2e (or MT CO2e) per year (MT CO2e/year) for all land use types. Therefore, projects that do not exceed the bright-line threshold would have a nominal and therefore less than cumulatively considerable impact on GHG emissions. • Tier 4—Performance Standards: If emissions exceed the numerical screening threshold, a more detailed review of the project’s GHG emissions is warranted. The SCAQMD has proposed an efficiency target for projects that exceed the bright-line threshold. The SCAQMD proposed a 2020 efficiency target of 4.8 MT CO2e per year per service population for project-level analyses LSA

Consistent with the SEIR, this analysis evaluates GHG emissions using the SCAQMD-recommended Tier 3 bright-line screening threshold of 3,000 MT CO2e per year and the project-specific efficiency threshold of 3.2 MT CO2e per service population per year. These thresholds were used to evaluate whether GHG emissions associated with the proposed off-site improvements would alter the significance conclusions presented in the SEIR.

IMPACT ANALYSIS
This section identifies potential construction-related air quality and GHG impacts associated with implementation of the proposed off-site improvements.

Air Quality Impacts
Air pollutant emissions associated with the proposed off-site improvements would occur from shortterm construction activities, as described in the following discussion.

Short-Term Construction Emissions
During construction, short-term degradation of air quality may occur due to the release of particulate matter emissions (i.e., fugitive dust) generated by excavation, trenching, grading, pavement removal and replacement, and backfilling activities. Emissions from construction equipment are also anticipated and would include CO, NOX, VOC, directly emitted PM2.5 or PM10, and toxic air contaminants (TACs) such as diesel exhaust particulate matter (DPM).

Construction of the off-site improvements would include excavation, trenching, utility installation, pavement restoration, and associated roadway improvements. Sources of fugitive dust would include disturbed soils at the construction site. The SCAQMD has established Rule 403: Fugitive Dust, which would require the applicant to implement measures that would reduce the amount of particulate matter generated during the construction period.

In addition to dust-related PM10 emissions, heavy trucks and construction equipment powered by gasoline and diesel engines would generate CO, SOX, NOX, VOCs, and some soot particulate (PM2.5 and PM10) in exhaust emissions. If construction activities were to increase traffic congestion in the area, CO and other emissions from traffic would increase slightly while those vehicles idle in traffic.

These emissions would be temporary in nature and limited to the immediate area surrounding the construction site.

Construction emissions were estimated for the off-site improvements using CalEEMod and are summarized in Table C. CalEEMod output sheets are included in Attachment C.

As shown, the construction emissions associated with the proposed off-site improvements are below the applicable SCAQMD regional significance thresholds. The off-site improvements represent an incremental addition to the overall One Beverly Hills project construction emissions. The maximum daily emissions evaluated in the SEIR and presented in Table 10.1-9 include the following: 18 lbs/day LSA

VOCs, 169 lbs/day NOX, 176 lbs/day CO, 1 lb/day SO2, 27 lbs/day PM10 and 9 lbs/day PM2.5. Maximum daily NOX emissions were predominantly generated by the mass grading phase of the project during year two of construction. The maximum daily emissions of NOX substantially reduced in subsequent years of construction. Year two of construction has been completed. Accordingly, given the current phase of constructionthe proposed off-site improvements would not combine with onsite emissions to substantially increase the construction emissions that formed the basis of the SEIR’s air quality conclusions.

In addition, the SEIR identified construction-related air quality impacts associated with emissions of NOX and adopted MM AQ-1 through MM AQ-17 to reduce construction emissions and minimize impacts to nearby sensitive receptors. These measures include requirements related to construction equipment, construction traffic management, fugitive dust control measures, and construction best management practices. The proposed off-site improvements would be subject to applicable construction air quality mitigation measures identified in the SEIR. Accordingly, the proposed off-site improvements do not alter the SEIR’s determination, and mitigation measures identified remain applicable. Therefore, the SEIR’s air quality conclusions remain unchanged.

Localized Impact Analysis
Off-site improvement construction emissions were compared to the LST screening tables in SRA 2, based on a 25-meter source-receptor distance and a disturbed acreage threshold of 1 acre for construction projects. Table D shows the results of the LST analysis during off-site improvement construction.

As shown in Table D, localized construction emissions associated with the off-site improvements do not exceed the applicable SCAQMD localized significance thresholds. The LST analysis evaluates the highest-emitting construction activities occurring at the nearest sensitive receptor, representing a conservative worst-case assessment of localized impacts. Construction activities with lower emissions and/or occurring farther from sensitive receptors would result in lower localized pollutant concentrations. Therefore, implementation of the proposed off-site improvements would not result in significance localized impacts.

The proposed off-site improvements would not alter the One Beverly Hills Overlay Specific Plan Project’s consistency with the applicable air quality management plan or result in other air quality impacts beyond those evaluated herein. Additionally, construction of the proposed off-site improvements would result in temporary DPM emissions from diesel-powered construction equipment. As the off-site improvements represent only a minor component of the overall project construction activities and generate lower emissions than those evaluated in the SEIR, they would not result in a substantial increase in TAC impacts or alter the SEIR’s conclusions.

Since construction emissions associated with the off-site improvements are below the regional and localized thresholds of significance and there are no operation-related emission sources, the proposed off-site improvements are not expected to result in significant odor impacts or other air quality effects beyond those addressed in this memorandum.

Greenhouse Gas Impacts
GHG emissions associated with the off-site improvement project would occur from short-term construction activities.

Generation of Greenhouse Gas Emissions
Construction Emissions. Construction activities associated with the proposed off-site improvement would produce combustion emissions from various sources. Construction would emit GHGs through the operation of construction equipment and from worker and builder supply vendor vehicles during the construction period. The combustion of fossil-based fuels creates GHGs such as CO2, CH4, and N2O. Furthermore, the fueling of heavy equipment emits CH4. Exhaust emissions from on-site construction activities would vary daily as construction activity levels change.

As indicated above, the SCAQMD does not have an adopted threshold of significance for construction-related GHG emissions. However, it is best practice for lead agencies to quantify and disclose GHG emissions that would occur during construction. The SCAQMD recommends the construction GHG emissions to be amortized over the life of the project (which is defined as 30 years), added to the operational emissions, and compared to the applicable interim GHG LSA

MT CO2e/yr = metric tons of carbon dioxide equivalent per year SEIR = Supplemental Environmental Impact Report
SP = Specific Plan
As shown in Table E, construction of the proposed off-site improvements would generate approximately 84.1 MT CO2e during construction. When amortized over a 30-year project life, construction GHG emissions of the proposed off-site improvements would equal approximately 2.8 MT CO2 per year, a fraction of the overall construction emissions. When combined with the SEIR emissions of the full project, the overall GHG emissions would still be below the threshold.

The SEIR concluded that project-related GHG emissions would be less than significant and did not require GHG mitigation measures. Rather, the EIR identifies numerous sustainability features, including commitments to achieve LEED and WELL certification, as well as energy- and waterefficient building design features that reduce long-term operational energy use and GHG emissions.

The proposed off-site improvements would not modify these sustainability features. As such the GHG conclusions presented in the SEIR remain applicable to the proposed off-site improvements.

CONCLUSION
Based on the analysis presented above, the proposed off-site improvements would not result in a substantial increase in the severity of air quality or GHG emissions impacts as compared to those disclosed in the SEIR. Regional construction emissions and localized impacts associated with the offsite improvements remain below the applicable SCAQMD significance thresholds. Construction GHG emissions associated with off-site improvements do not alter the SEIR’s significance determination.

Accordingly, the proposed off-site improvements would not change the air quality or GHG conclusions presented in the SEIR.

• The project applicant and/or contractor shall designate a person located on-site who is trained and certified by CARB to conduct visible emissions evaluations (VEE). The designated person shall ensure compliance with SCAQMD Rule 403 by observing for visible dust emissions beyond the property line during daytime working hours. Observations shall be conducted in accordance with USEPA Method 9 (Title 40, Code of Federal Regulations, Part 60, Appendix A). • The project applicant and/or contractor shall obtain a schedule of outdoor activities and athletic events at El Rodeo School and Beverly Hills High School during the construction period from the City or the Beverly Hills Unified School District as soon as the information becomes available, The City shall immediately provide this information to the project applicant and contractor.

Provided that the Beverly Hills Unified School District has provided the scheduling information in a timely manner, the project applicant and contractor shall require coordination of all construction activities so as to minimize the occurrence of high-emitting fugitive dust construction activities during the scheduled outdoor events to the extent feasible.

• In the event visible dust emissions are observed beyond the property line, the designated person shall immediately inform a lead supervisor or other appropriate managing personnel. The supervisor shall immediately implement corrective measures. If visible dust emissions are anticipated to impact El Rodeo School, the supervisor shall notify the Principal of El Rodeo School and the Beverly Hills Unified School District Superintendent. If immediate implementation of a corrective measure shall result in the creation of a hazardous situation, construction activity shall be allowed to continue for a reasonable period of time until such time that it is safe to implement corrective measures. Corrective measures shall be documented by the construction contractor in a logbook accessible to a third-party air quality consultant and the City of Beverly Hills. Records shall be maintained of the specific action taken, the time and date the corrective action was taken, and written verification by the appropriate on-site construction manager or supervisor that the corrective action was taken.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

The sensitivity score reflects the extent to which a project would be adversely affected by exposure to a climate hazard. Exposure is rated on a scale of 1 to 5, with a score of 5 representing the greatest exposure.

The adaptive capacity of a project refers to its ability to manage and reduce vulnerabilities from projected climate hazards. Adaptive capacity is rated on a scale of 1 to 5, with a score of 5 representing the greatest ability to adapt.

The overall vulnerability scores are calculated based on the potential impacts and adaptive capacity assessments for each hazard. Scores do not include implementation of climate risk reduction measures.

OBH Off-Site Improvements (Area 2) Detailed Report, 7/30/2026

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

The sensitivity score reflects the extent to which a project would be adversely affected by exposure to a climate hazard. Exposure is rated on a scale of 1 to 5, with a score of 5 representing the greatest exposure.

The adaptive capacity of a project refers to its ability to manage and reduce vulnerabilities from projected climate hazards. Adaptive capacity is rated on a scale of 1 to 5, with a score of 5 representing the greatest ability to adapt.

The overall vulnerability scores are calculated based on the potential impacts and adaptive capacity assessments for each hazard. Scores do not include implementation of climate risk reduction measures.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat 18 / 27
OBH Off-Site Improvements (Area 3) Detailed Report, 7/30/2026 Climate Hazard Result for Project Location Unit
Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat 18 / 27
OBH Off-Site Improvements (Area 4) Detailed Report, 7/30/2026 Climate Hazard Result for Project Location Unit
Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
22 / 32
OBH Off-Site Improvements (Area 5) Detailed Report, 7/30/2026 Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

OBH Off-Site Improvements (Area 6) Detailed Report, 7/30/2026

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

OBH Off-Site Improvements (Area 7) Detailed Report, 7/30/2026

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Air Quality Degradation N/A N/A N/A N/A
The sensitivity score reflects the extent to which a project would be adversely affected by exposure to a climate hazard. Exposure is rated on a scale of 1 to 5, with a score of 5 representing the greatest exposure.

The adaptive capacity of a project refers to its ability to manage and reduce vulnerabilities from projected climate hazards. Adaptive capacity is rated on a scale of 1 to 5, with a score of 5 representing the greatest ability to adapt.

The overall vulnerability scores are calculated based on the potential impacts and adaptive capacity assessments for each hazard. Scores do not include implementation of climate risk reduction measures.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
22 / 32
OBH Off-Site Improvements (Area 8) Detailed Report, 7/30/2026 Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures 15 / 24
OBH Off-Site Improvements (Total Site Paving) Detailed Report, 7/31/2026 from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73000 annual days of extreme heat Extreme Precipitation 7.05000 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30000 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

TO: BriƩany KnoƩ, Cain Development, LP
FROM: Jason Lui, Associate/Senior Noise Specialist
SUBJECT: One Beverly Hills Underground Electrical Infrastructure Extension ConstrucƟon Noise and VibraƟon Impact Analysis (LSA Project No. 20263059)

INTRODUCTION
This ConstrucƟon Noise and VibraƟon Impact Analysis has been prepared subsequent to the construcƟon noise and vibraƟon impact analysis in the One Beverly Hills Overlay Specific Plan Final Supplemental Environmental Impact Report (FSEIR) (Rincon Consultants, Inc. 2021) to assess the potenƟal noise and vibraƟon impacts of the extension of underground electrical infrastructure within exisƟng public roadway rights-of-way on South Santa Monica Boulevard, from Charleville Boulevard to approximately 20 linear feet east of the Wilshire Boulevard intersecƟon, associated with the One Beverly Hills Project (project). All references cited in this assessment are provided in AƩachment A.

PROJECT LOCATION
The extension of the underground electrical infrastructure associated with the project is located within the exisƟng public roadway right-of-way on South Santa Monica Boulevard, from Charleville Boulevard approximately 20 linear feet east of the Wilshire Boulevard intersecƟon in Beverly Hills, California. Figure 1 shows the project locaƟon (all figures are provided in AƩachment B).

PROJECT DESCRIPTION
The proposed project consists of the extension of the underground electrical infrastructure within exisƟng public roadway rights-of-way, including the construcƟon of underground conduit systems, uƟlity vaults, vent lines, and associated street restoraƟon improvements. ConstrucƟon acƟviƟes would occur primarily along South Santa Monica Boulevard, the Wilshire Boulevard crossing, and Charleville Boulevard. Figure 2 shows the project construcƟon boundary.

The work would be completed over an approximately 39-day construcƟon period and would occur enƟrely within previously disturbed urban roadway corridors. Major construcƟon acƟviƟes include LSA
50 EI 9e
8/6/26 (P:\2026\20263059-One Beverly Hills\Product\Noise\Noise Memo_20260806.docx) 2 uƟlity potholing, saw cuƫng, asphalt milling and removal, trench excavaƟon, installaƟon of underground electrical conduits, construcƟon and placement of precast electrical vaults, installaƟon of vent line conduits, slurry backfilling, aggregate base placement, asphalt pavement restoraƟon, and final pavement striping. Temporary traffic control measures would be implemented throughout construcƟon, with steel trench plates installed at the end of each workday to maintain vehicular access where excavaƟons remain open.

ConstrucƟon would begin with uƟlity potholing and conflict idenƟficaƟon using hydro-vacuum excavaƟon equipment, followed by saw cuƫng and asphalt milling of exisƟng pavement surfaces.

ExcavaƟon acƟviƟes would include the removal of approximately 2,500 cubic yards of trench material and approximately 215 cubic yards of asphalt pavement. ExcavaƟons would support the installaƟon of approximately 795 linear feet of mainline electrical conduit within South Santa Monica Boulevard, associated vent line conduits, and two underground electrical vault structures.

Approximately, 50 linear feet of conduit would be installed in Charleville Boulevard north of South Santa Monica Boulevard.

Vault construcƟon would include excavaƟon, shoring installaƟon, placement of precast concrete vaults using hydraulic cranes, conduit connecƟons, and slurry backfill. Mainline conduit installaƟon would occur in mulƟple segments along South Santa Monica Boulevard, Charleville Boulevard, and the Wilshire Boulevard crossing. Vent line conduit installaƟons would be constructed adjacent to both vault locaƟons.

Backfill operaƟons would consist primarily of controlled low-strength material (CLSM) slurry placement, totaling approximately 1,100 cubic yards. Following uƟlity installaƟon, trench secƟons would be restored using crushed miscellaneous base and asphalt pavement. Approximately 68 cubic yards of aggregate base and 200 cubic yards of asphalt paving material would be imported and placed during roadway restoraƟon. Temporary pavement markings would be installed following paving operaƟons, with final lane striping completed aŌer the required asphalt curing period.

ConstrucƟon would require crews ranging from approximately 14 to 36 personnel per day, depending on the phase of work. Equipment anƟcipated during various phases of construcƟon includes hydraulic excavators, wheel loaders, hydro-vacuum excavaƟon trucks, asphalt milling machines, dump trucks, concrete mixer trucks, cranes, asphalt paving equipment, rollers, sweepers, water trucks, and pavement striping equipment.

Temporary impacts associated with construcƟon may include construcƟon-generated noise and vibraƟon. ConstrucƟon acƟviƟes would occur within developed urban transportaƟon corridors and would not introduce new permanent above-ground structures beyond standard uƟlity access features associated with underground electrical faciliƟes.

OperaƟonal impacts following construcƟon are expected to be minimal because the majority of the improvements would be located underground within exisƟng public rights-of-way.

CHARACTERISTICS OF SOUND
Sound is a vibratory disturbance created by a moving or vibraƟng source, which is capable of being detected by the hearing organs (e.g., the human ear). Noise is usually defined as unwanted sound.

Noise consists of any sound that may produce physiological or psychological damage and/or interfere with communicaƟon, work, rest, recreaƟon, and sleep.

To the human ear, sound has two significant characterisƟcs: pitch and loudness. Pitch is generally an annoyance, while loudness can affect the ability to hear. Pitch is the number of complete vibraƟons (or cycles per second) of a wave, resulƟng in the tone’s range from high to low. Loudness is the strength of a sound, describes a noisy or quiet environment, and is measured by the amplitude of the sound wave. Loudness is determined by the intensity of the sound waves combined with the recepƟon characterisƟcs of the human ear. Sound intensity is the average rate of sound energy transmiƩed through a unit area perpendicular to the direcƟon in which the sound waves are traveling. This characterisƟc of sound can be precisely measured with instruments.

In the analysis of a project, the noise environment of the project area is defined in terms of sound intensity and its effect on adjacent sensiƟve land uses.

Measurement of Sound
Sound intensity is measured through the A-weighted scale to correct for the relaƟve frequency response of the human ear. That is, an A-weighted noise level de-emphasizes low and very high frequencies of sound similar to the human ear’s de-emphasis of these frequencies. Decibels (dB), unlike the linear scale (e.g., inches or pounds), is a scale based on powers of 10.

For example, 10 dB is 10 Ɵmes more intense than 0 dB, 20 dB is 100 Ɵmes more intense than 0 dB, and 30 dB is 1,000 Ɵmes more intense than 0 dB. Thirty decibels (30 dB) represents 1,000 Ɵmes as much acousƟc energy as 0 dB. The decibel scale increases as the square of the change, represenƟng the sound pressure energy. A sound as soŌ as human breathing is about 10 Ɵmes greater than 0 dB.

The decibel system of measuring sound gives a rough connecƟon between the physical intensity of sound and its perceived loudness to the human ear. A 10 dB increase in sound level is perceived by the human ear as only a doubling of the loudness of the sound. Ambient sounds generally range from 30 A-weighted decibels (dBA) (very quiet) to 100 dBA (very loud).

Sound levels generate from a source, and their decibel level decreases as the distance from that source increases. Sound dissipates exponenƟally with distance from the noise source. For a single point source, sound levels decrease approximately 6 dB for each doubling of distance from the source. This drop-off rate is appropriate for noise generated by staƟonary equipment. If noise is produced by a line source, such as highway traffic or railroad operaƟons, the sound decreases 3 dB for each doubling of distance in a hard site environment. Line source noise in a relaƟvely flat environment with absorpƟve vegetaƟon decreases 4.5 dB for each doubling of distance.

There are many ways to rate noise for various Ɵme periods, but an appropriate raƟng of ambient noise affecƟng humans also accounts for the annoying effects of sound. The equivalent conƟnuous sound level (Leq) is the total sound energy of Ɵme-weighted average noise over a sample period.

However, the predominant raƟng scales for human communiƟes in California are Leq and the Community Noise Equivalent Level (CNEL) or the day-night average noise level (Ldn) based on dBA.

Ldn is similar to the CNEL scale but without the adjustment for events occurring during the relaxaƟon hours. CNEL and Ldn are within 1 dBA of each other and are normally interchangeable. The noise adjustments are added to the noise events occurring during the more sensiƟve hours.

Other noise raƟng scales of importance, when assessing the annoyance factor, include the maximum instantaneous noise level (Lmax), which is the highest exponenƟal Ɵme-averaged sound level that occurs during a stated Ɵme period. The noise environments discussed in this analysis are specified in terms of Lmax for short-term noise impacts. Lmax reflects peak operaƟng condiƟons and addresses the annoying aspects of intermiƩent noise. Another noise scale oŌen used together with Lmax in noise ordinances for enforcement purposes is noise standards in terms of percenƟle noise levels. For example, the L10 noise level represents the noise level exceeded 10 percent of the Ɵme during a stated period. The L50 noise level represents the median noise level; half the Ɵme the noise level exceeds this level and half the Ɵme it is less. The L90 noise level represents the noise level exceeded 90 percent of the Ɵme and is considered the background noise level during a monitoring period. For a relaƟvely constant noise source, Leq and L50 are approximately the same.

Noise impacts can be described in three categories. The first is audible impacts, which refer to increases in noise levels noƟceable to humans. Audible increases in noise levels generally refer to a change of 3 dB or greater since this level has been found to be barely percepƟble in exterior environments. The second category, potenƟally audible, refers to a change in the noise level between 1 dB and 3 dB. This range of noise levels has been found to be noƟceable only in laboratory environments. The last category is changes in noise levels of less than 1 dB, which are inaudible to the human ear. Only audible changes in exisƟng ambient or background noise levels are considered potenƟally significant.

Physiological Effects of Noise
Physical damage to human hearing begins at prolonged exposure to noise levels higher than 85 dBA.

Exposure to high noise levels affects the enƟre system, with prolonged noise exposure in excess of 75 dBA increasing body tensions and thereby affecƟng blood pressure and funcƟons of the heart and the nervous system. In comparison, extended periods of noise exposure above 90 dBA would result in permanent cell damage. When the noise level reaches 120 dBA, a Ɵckling sensaƟon occurs in the human ear, even with short-term exposure. This level of noise is called the threshold of feeling. As the sound reaches 140 dBA, the Ɵckling sensaƟon is replaced by the feeling of pain in the ear. This is called the threshold of pain. Sound levels from 160 to 165 dBA will potenƟally result in dizziness or loss of equilibrium. The ambient or background noise problem is widespread and generally more concentrated in urban areas than in outlying, less developed areas. Table A lists definiƟons of acousƟcal terms, and Table B shows common sound levels and their noise sources.

Term DefiniƟon
Decibel, dB A unit of noise level that denotes the raƟo between two quanƟƟes that are proporƟonal to power; the number of decibels is 10 Ɵmes the logarithm (to the base 10) of this raƟo.

Frequency, Hz Of a funcƟon periodic in Ɵme, the number of Ɵmes that the quanƟty repeats itself in 1 second (i.e., number of cycles per second).

A-Weighted Sound Level, dBA The sound level obtained by use of A-weighƟng. The A-weighƟng filter de-emphasizes the verylow-frequency and very-high-frequency components of the sound in a manner similar to the frequency response of the human ear and correlates well with subjecƟve reacƟons to noise. (All sound levels in this report are A-weighted unless reported otherwise.) L2, L8, L50, L90 The fast A-weighted noise levels that are equaled or exceeded by a fluctuaƟng sound level 2 percent, 8 percent, 50 percent, and 90 percent of a stated Ɵme period.
