Irwindale City Council
November 24, 2025

Resolution No. 2025-108-3696
SP&DR(DA) No. 03-2025

verbal testimony, site plans and Conditions of Approval attached hereto as Exhibit “A,” this City Council hereby specifically finds as follows:

After conducting a public hearing, the City Council must make all of the following findings in order to approve or conditionally approve a Zone Variance application. The City Council shall deny an application for a Zone Variance if it is unable to make any of the required findings, in which case it shall state the reasons for that determination.

A. Exceptional or Extraordinary Circumstances. There are exceptional or extraordinary circumstances or conditions applicable to the property involved that do not apply generally to property in the vicinity and identical zone, and that the granting of a Zone Variance will not constitute a granting of a special privilege inconsistent with the limitations on the property in the vicinity and identical zone.

The Project site is within the IGSP. There are no other properties within the vicinity and the SP Zone that are subject to the requirement to underground a 220kV transmission line or limit the maximum height of the line and related facilities (including the POCO pole) to 65’. Therefore, there are exceptional or extraordinary circumstances or conditions applicable to the Property that do not apply generally to property in the vicinity and identical zone. The allowed uses of other properties in the vicinity do not require construction of a new 220kV transmission line connecting to SCE’s overhead lines at an adequate height to safely cross the public ROW without conflicts with existing infrastructure. The granting of the Zone Variance to allow an overhead tie-line and POCO pole exceeding the maximum structure height limit on the Project site simply allows the Property the benefit of safe and efficient development of its allowed use in the specific plan. Therefore, granting the Zone Variance would not constitute a special privilege inconsistent with the limitations on the property in the vicinity and identical zone.

B. Special Property Circumstances. The Zone Variance is a process for the City to waive or modify certain standards of the Zoning Code when, because of special circumstances applicable to the property, including location, shape, size, surroundings, topography or other physical features, the strict application of the Code denies the property owner privileges enjoyed by other property owners in the same zone. A Zone Variance cannot be used to grant a special privilege not afforded to other property owners similarly situated.

Due to special circumstances applicable to the Property, including its location adjacent to the ROW and SCE Rio Hondo Substation, which precludes locating the POCO pole outside the Property and Specific Plan area, and the requirement to construct a new 220kV transmission line connecting to SCE’s overhead lines at an adequate height (130’) to safely cross the public ROW without conflicts with existing infrastructure (including lower-voltage lines), the strict application of the Code would deny the Project applicant privileges to develop the allowed use on the Property in a safe and efficient manner. The granting of the Zone Variance to allow an overhead tie-line and POCO pole exceeding the maximum structure

Resolution No. 2025-108-3696
SP&DR(DA) No. 03-2025

height limit on the Project site simply allows the Property the benefit of safe and efficient development of its allowed use in the specific plan. Therefore, granting the Zone Variance would not grant the Project applicant a special privilege not afforded to other property owners similarly situated.

C. Physical Hardship. The granting of the application is necessary to prevent a physical hardship which is not of the applicant’s own actions or the actions of a predecessor in interest.

The Zone Variance is necessary to prevent a physical hardship that is not of the applicant’s own actions or the actions of a predecessor in interest. SCE has advised the City in writing that it requires an overhead configuration for the tie-line due to both design, physical and safety constraints precluding an underground tieline. A minimum height of 130’ is required to avoid conflicts with existing lines (including lower-voltage distribution lines) and SCE infrastructure and connect to the SCE Rio Hondo Substation at the designated location). SCE does not permit privately owned facilities (including the POCO pole) to be located within their substation property, and there is no private property between the Project site, ROW and Rio Hondo Substation, that could accommodate the POCO pole outside the Property and Specific Plan area. Without the Zone Variance from the provision of the IGSP’s undergrounding requirement and 65’ height limit, the Project applicant would suffer a physical hardship because it would not be feasible to connect the Project tie-line to the SCE overhead line at a sufficient height to safely cross the ROW. This physical hardship is created by SCE and the California Public Utilities Commission (CPUC) regulations, not the Project applicant’s actions or those of a predecessor in interest. Accordingly, the Zone Variance is necessary to prevent a physical hardship which is not of the applicant’s own actions or the actions of a predecessor in interest.

D. No Determent to Public Welfare. The granting of the application will not be detrimental or injurious to property or improvements in the vicinity, and will not be detrimental to the public health, safety, general welfare, or convenience.

Granting the Zone Variance will not be detrimental or injurious to property or improvements in the vicinity or to the public health, safety, general welfare, or convenience. Without granting the Zone Variance, the Project and related tie-line could not be constructed because it is not feasible to underground the portion of the tie-line between the dead-end structure and the POCO and connect to the SCE portion of the tie-line at a minimum height of 130’ to safely cross Live Oak Avenue.

Without development of the energy storage facility with an underground line, the detriment to public health, safety, general welfare, or convenience would increase because the public would be denied the opportunity to further decarbonize California’s electrical grid. Energy storage facilities are being developed to satisfy state mandates on utility companies to procure specified amounts of energy storage to improve the reliability of an electrical grid that is increasingly dependent upon renewable energy, which is part of the state’s plan to halt the growth of

Resolution No. 2025-108-3696
SP&DR(DA) No. 03-2025

greenhouse gas emissions produced during the generation and distribution of energy. California has determined that elevated greenhouse gas emissions are harmful to the public and California, due to its impact on global warming, which increases the intensity of severe weather events and wildfires.

Granting the Zone Variance also facilitates the safe transmission of electrical energy to the SCE Rio Hondo Substation and ultimately the electricity grid. A Zone Variance to allow an overhead tie-line and POCO pole exceeding 65’ is required in order to connect the Project to SCE’s overhead line at a sufficient height to provide safe clearances across Live Oak Avenue. The overhead tie-line will be designed and operated in accordance with requirements of SCE and the California Public Utility Commission for safety. The Zone Variance will ensure the Project will be constructed safely without conflicts with existing electrical lines.

The proposed POCO pole and overhead lines are consistent with existing overhead crossings in this area and will not be detrimental or injurious to property or improvements in the vicinity. As discussed in Westwood’s memo, the nearest non-utility infrastructure to this crossing are industrial buildings approximately 0.15 miles away. Additional commercial properties are within 0.5 miles. Residential properties more sensitive to visual impact are over 0.5 miles from the crossing.

The overhead tie-line was evaluated in the Environmental Impact Report for the Irwindale Gateway Specific Plan and the Environmental Impact Report did not identify any significant impacts related to the tie-line. Moreover, the design with the Zone Variance permits the POCO to be located further from Live Oak Avenue, reducing visual impacts from the public ROW. Therefore, granting the Zone Variance will not be detrimental or injurious to property or improvements in the vicinity.

In addition, the proposed tie-line from the subject property to the Rio Hondo substation to the south would run perpendicular to those lines, causing significant risk between the gas line and the thermal buildup that underground cables can be prone to. In addition to the thermal buildup, SCE also had concerns including but not limited to construction complexity, restoration and access limitations, and the lack of design standards for underground 220kV transmission lines.

Based on these factors, the granting of the Zone Variance to allow the overhead tie-line and permit the POCO to exceed the maximum structure height limit will not be detrimental or injurious to property or improvements in the vicinity, and will not be detrimental to the public health, safety, general welfare, or convenience.

E. Consistency. The granting of the Zone Variance will be consistent with the general purposes and objectives of this Title, any applicable specific plans and the General Plan.

Approval of the Zone Variance will be consistent with the general purposes and objectives of IMC Title 17, any applicable specific plans and the General Plan. All

Resolution No. 2025-108-3696
SP&DR(DA) No. 03-2025

applicable procedures and processes outlined in Title 17 will be adhered to. The Specific Plan anticipates allowing an overhead tie-line with a Zone Variance where the applicable agency(ies) reject the proposed underground line. The City has received written correspondence from SCE, advising that it requires an overhead configuration for the tie-line due to both design and physical constraints precluding an underground tie-line. Accordingly, granting of the Zone Variance is consistent with the Specific Plan. Similarly, IMC Subsection 17.40.040(B)(4) anticipates allow above-ground connectivity with a Zone Variance. Accordingly, allowing overhead facilities upon making the required Zone Variance findings herein is consistent with IMC Title 17.

Moreover, a Zone Variance from the maximum 65’ height limit for the highest structure for the onsite substation (Table 6-3, Footnote 5) is necessary in order to accommodate the high-voltage tie-line with safe clearances from existing electrical lines (including lower-voltage distribution lines) and will support orderly development of the City. Accordingly, the Variance is consistent with the general purposes and objectives of the IMC Title 17.

The Zone Variance is also consistent with the City of Irwindale General Plan which includes policies and programs to promote use of photovoltaic systems and conserve non-renewable resources including energy. The tie-line will transmit high voltage energy to and from the SCE Rio Hondo Substation and battery energy storage system, which can help conserve non-renewable systems and promote use of renewable sources including photovoltaic systems, stabilize rapid changes in electric power demand and support power demand when needed thereby enhancing grid reliability and contributing to public health and safety.

Based on these factors, the granting of the Zone Variance to allow the overhead tie-line and permit the POCO to exceed the maximum structure height limit to provide for the safe and efficient operation of the Project and related tie-line will be consistent with the general purposes and objectives of IMC Title 17, any applicable specific plans and the General Plan.

3. Pursuant to the authority and criteria contained in the California Environmental Quality Act (CEQA) of 1970, as amended, and the City of Irwindale environmental guidelines, the City, as the Lead Agency, has analyzed the project, and has determined that the proposed Battery Energy Storage System (BESS) was fully analyzed in the Environmental Impact Report for the Irwindale Gateway Specific Plan (SCH No. 2023020290), City’s General Plan and, pursuant to CEQA Guidelines Sections 15183 and 15162, and is consistent with the previously certified EIR, therefore no subsequent EIR, Negative Declaration, or addendum is required for approval of the proposed BESS project. A copy of the EIR and Mitigation Monitoring and Reporting Program was posted on the project’s dedicated website
https://www.irwindaleca.gov/590/13620-Live-Oak-Lane---Irwindale-Gateway-.

Subject: Southern California Edison Findings Justifying an Overhead Design of 220kV Generation Tie Line – Gabriel Battery Energy Storage System (BESS) Dear City of Irwindale Planning Division,
Southern California Edison (SCE) respectfully submits this response to the City of Irwindale’s July 30, 2025, letter regarding the proposed overhead design for the 220kV generation tie line associated with the Gabriel Battery Energy Storage System (BESS). We understand the City’s interest in exploring underground alternatives. After review, SCE has determined that an overhead configuration of the 220kv transmission line is required and offers the following findings justifying the requirement for an overhead configuration:

Thermal and Ampacity Constraints
Underground cables are more prone to thermal buildup. Faults can cause localized heating that damages insulation and surrounding duct banks, complicating fault detection and requiring cable ampacity derating, which negatively impacts system performance and interferes with the operation of utility facilities.

Construction Complexity
Underground installation requires extensive civil work, including several 30' x 6' duct banks, manholes, and vaults, which would disrupt traffic, pedestrian rights-of-way, and local infrastructure. Existing third-party underground utilities would need to be relocated, adding complexity and cost.

Restoration and Access Limitations - Underground Systems Underground faults are significantly more difficult to detect and repair than overhead faults, often resulting in longer outage durations. Restoration of high-voltage underground faults— such as those in 220kV systems—can take weeks to months, due to the need for excavation, permitting, coordination with other utilities, and environmental constraints. In contrast, overhead faults are typically resolved within hours to days.

The proposed underground system would be buried beneath roads, sidewalks, and other infrastructure, requiring traffic control, civil excavation, and municipal coordination to access faulted segments. These requirements introduce logistical complexity and further extend outage timelines.

ATTACHMENT "F"

Additionally, working within confined underground vaults or manholes presents serious safety risks, including potential gas accumulation, electrical hazards, and limited egress, which complicate emergency response and worker safety.

Design Standards
SCE does not currently have design standards for underground 220kV transmission lines.

Proceeding without these standards would introduce significant design risks and uncertainties.

Cost Considerations
Underground 220kV lines can cost 3 to 5 times more than overhead construction, significantly impacting both project economics and ratepayer protections.

Land Rights
SCE may need to acquire a new underground easement from the city in lieu of relying on existing franchise rights due to the nature and complexity of the infrastructure.

Regulatory Context
The 220kV transmission line extending from the BESS project site over the City right of way is part of SCE electric facilities upon completion and connection to the SCE substation. The construction, operation, and maintenance of SCE electric facilities is governed by the California Public Utilities Commission (CPUC) through General Order 131-E which holds that, “local jurisdictions acting pursuant to local authority are preempted from regulating electric power line projects, distribution lines, substations, or electric facilities constructed by public utilities subject to the Commission’s jurisdiction.”
Conclusion
In light of the regulatory, technical, environmental, and financial considerations outlined above, Southern California Edison (SCE) has determined that the overhead design for the 220kV generation tie line associated with the Gabriel Project is the most necessary, practical and costeffective solution and is therefore the required design. The overhead configuration not only aligns with existing design standards and regulatory requirements but also mitigates the

significant design and safety risks as well as operational and cost impacts associated with underground installations. We appreciate the City of Irwindale's interest in exploring alternatives and remain committed to working collaboratively to ensure the successful completion of this critical infrastructure project.

Sincerely,

Attached are the maps of the water lines that are on Live Oak Ave by Gateway. The clearest map would be the page 4 of the attached PDF. The blue lines shown on there are the locations of the water lines. Please note that the water company said these are “for information only. Distances and locations may be distorted and not suitable for legal, engineering, or surveying purposes” I asked Valley County Water if they knew the depths of the lines but they stated that we would need to pothole to verify. Looks like this is the best they can offer.

I reached out to So Cal Gas and am waiting to hear back from them. Once we receive those, I’ll forward them over to you.

Thank you,

Re: SoCalGas Comments Regarding Aypa Power’s Overhead Generation Tie-Line Request – Gabriel Battery Energy Storage Project
City of Irwindale Planning Division:

SoCalGas has reviewed Aypa Power’s proposed Gabriel Battery Energy Storage Project and identified the location where the proposed 220 kV electrical tie-line would intersect an existing 8-inch High Pressure (HP) SoCalGas natural gas pipeline along Live Oak Avenue in Irwindale, CA. SoCalGas’ review of the project scope and field data indicates a low risk of interference with our Cathodic Protection.

In addition, the existing 8-inch gas main is classified as a HP line and therefore a high-priority substructure. The greatest risk to SoCalGas pipeline facilities is third-party dig-ins, particularly around HP lines. For this reason, SoCalGas Distribution is in alignment with an aboveground installation of the proposed 220kV electrical tie-line rather than an underground installation to reduce excavation-related risks and help maintain the safety and integrity of HP facilities critical to SoCalGas operations.

Sincerely,
Dustin Tomlinson

Re: Findings in Support of Overhead Generation Tie-Line Variance - Gabriel Battery Energy Storage System (BESS)
File 0060332.01
To: City of Irwindale, Planning Division
From: Brandon Farrell, Director, Transmission Engineering - Westwood City of Irwindale Planning Division:

Westwood respectfully submits these findings (Findings) in support of the generation tie-line (gen-tie) variance request for the Gabriel Battery Energy Storage System (BESS) project. The Findings demonstrate that an overhead transmission design across Live Oak Avenue in the City of Irwindale, California is the sole feasible and safe design option, required to achieve reliable interconnection and ensure compliance with applicable municipal and state standards.

Westwood is a multi-disciplinary engineering firm, established in 1972, with decades of experience in overhead and underground transmission lines. Our team of Civil, Electrical, and Mechanical engineers have supported projects for investor-owned-utilities, municipalities, and developers of Wind, Solar, and BESS assets throughout the country, including in the state of California. Through the various services at Westwood, we are well versed in all facets of these projects at all stages of the project lifecycle, from preliminary planning to execution of construction.

We are confident in our assessment of the Live Oak Avenue crossing and the concerns with approaching this crossing using an underground circuit.

The technical and engineering findings confirm that undergrounding the Gabriel BESS gentie across Live Oak Avenue is not a feasible or consistent design option under applicable standards.

Both underground and overhead approaches would require structures exceeding 65 feet in height, with undergrounding introducing added design and construction complications, including either jack-and-bore pits or open trenches with extended road closures. The underground option also introduces utility conflicts, future risks to contractors working on those utilities, ADA compliance cocnerns, and significant public disruption. By contrast, an overhead crossing aligns with existing utility infrastructure in the corridor, ensures compliance with the Irwindale Specific Plan, Municipal Code, and electrical safety standards, and minimizes both construction impacts and long-term maintenance risks. Westwood’s Findings—together with those submitted by Southern California ATTACHMENT "J"

MEMORANDUM
Edison (SCE)—demonstrate that approval of the requested variance is necessary for the Gabriel BESS to proceed safely, efficiently, and in full consistency with Irwindale Zoning Code §17.32.06.

MEMORANDUM
Findings

1. Exceptional or Extraordinary Circumstances
There is currently significant overhead electrical infrastructure in and around the properties in question for the crossing of Live Oak Avenue. These lines range from low-voltage distribution lines to high-voltage transmission lines of significant height. A requirement to cross underneath Live Oak Ave would be inconsistent with the other power line crossings in this area.

With an overhead approach, height of new structures will depend greatly on the placement of the structure within the SCE yard and the number of overhead electrical crossings in that path. Due to the distribution-level circuits adjacent to Live Oak Avenue, the new transmission structures will need to be greater than 65’ above ground height to allow for clearances that meet the minimum code requirements (EX. National Electric Safety Code, California General Order 95). While we cannot accurately confirm the height of those assets along the road at this time, the circuits are likely 25ft above ground, on the lower end. A 220kV riser structure would utilize a phase spacing of roughly 15ft between phases and shield wires, totaling about 45ft for the “power space.” Additionally, NESC requires roughly 7ft of clearance between the 220kV phases and the existing lines, assuming voltage is somewhere between 22kV and 69kV. This would result in a structure of at least 80ft tall, which is a conservative estimate pending further review of the assets along Live Oak Avenue. The existing structures that support crossings over Live Oak Avenue within 100 Yards of this crossing are currently well in excess of 65’ in height. The need for structures exceeding 65’ would not constitute granting a special privilege inconsistent with the limitations on the property in the vicinity and identical zone. With the underground design approach, the riser structure will still be required to exceed 65’ above ground height to allow for the wires to cross over the existing overhead electric on the South side of Live Oak Avenue. Effectively, the 65’ height requirement is infeasible with either approach.

An underground transmission line crossing Live Oak Ave involves unique challenges due to the need for trenchless Jack & Bore installation. This would require a large jacking pit on the north side of Live Oak Ave, and a slightly smaller exit pit, approximately 25'L x 15'W x 20'D, necessitating significant lane closures and utility relocation. If a jack & bore approach was not used in favor of a more traditional duct-bank installation, significant roadway closures would be needed for the duration that the trench is open during construction. As such, the Jack & Bore approach would be typical to avoid lane closures. However, due to inability to place an Aypa-owned structure within the SCE yard, the Jack & Bore pits would have to be within Live Oak Avenue, causing significant lane closures regardless. Westwood has typically seen crossings of this size require 3-5 weeks to construct, inclusive of road repairs. It would be reasonable to assume that road disruptions would be measured in a timeline of weeks, ersus the overhead conductor pulls which would last only minutes at a time.

MEMORANDUM

2. Special Property Circumstances.

Placement of overhead powerlines and structures on this property is consistent with the use of surrounding parcels. There are currently numerous overhead transmission crossings within 100 yards of the proposed crossing, some of significant height. Placement of an overhead powerline crossing in this area does not constitute a special privilege not afforded to other asset owners similarly situated. The requirement to bore underground would be considered the exception to the rule in this area.

As previously mentioned, with the use of an underground design, and the requirement to maintain the Point of Connection Pole (PCO) outside of the SCE yard, the only location to place a Riser structure would be within the sidewalk between Live Oak Avenue and the SCE yard wall due to the requirement at SCE that the underground portion of the gen-tie must remain outside of their yard. This constraint, coupled with ADA compliance and safety issues due to sidewalk placement, distinguishes this site from others where underground lines can be developed without such complications. The complexity of existing utilities adds substantial risk, increasing the chance of damage and service interruptions. To place a riser structure in this location would also require modification to the existing overhead lines on the South side of Live Oak Avenue to maintain proper electrical clearances. In addition to the modifications to the existing infrastructure, the riser structure would be required to provide the same electrical clearances as an overhead crossing of the roadway, resulting in a structure in excess of 65ft whether the crossing is overhead or underground. As noted previously, Westwood would anticipate the riser structure to be 80ft tall, at a minimum, to clear the existing circuits safely and may be taller depending on the placement of the next structure within the SCE yard.

3. Physical Hardship.

The requirement for the installation of an underground transmission line crossing across Live Oak Ave. would constitute a physical hardship not only to Aypa and SCE but, more importantly, for the public. Installation of an underground crossing would require a lengthy disturbance including closure of Live Oak Ave to allow for construction of the crossing, as previously noted, whether a traditional duct-bank design or a jack & bore approach is utilized. Additionally, the riser structure on the south side of Live Oak Avenue would not be allowed inside SCE’s property and would be required to be placed in the public ROW. This structure would need to be a self-supporting steel structure and would impede the existing sidewalk and violate ADA compliance without major rework impacting the road for an extended period of time. Placement of this structure will impact the existing overhead electric facilities on the south side of Live Oak Avenue as well, resulting in additional costs and disruptions to services.

MEMORANDUM
Future maintenance of Live Oak Ave, including maintenance on existing infrastructure in Live Oak Ave (water, sewer, gas, etc.) would be more difficult and dangerous with a high voltage underground crossing in place. Conversely, the construction of an overhead powerline crossing would produce relatively short durations of traffic disturbance on Live Oak Ave. The wires could be installed over Live Oak Ave. within one day and likely would only require rolling traffic stops for roughly 15 min at a time. The wires would be located high above ground level and would not present a risk to any person or equipment that is in the vicinity.

4. No Detriment to Public Welfare
It is our opinion that the presence of an overhead transmission line crossing will provide less impact to the public then to an underground transmission line crossing. Construction of an overhead crossing will have minimal impact on traffic and the existing sidewalks on Live Oak Ave. An underground crossing will require disturbance to the sidewalk on the south side of Live Oak Ave due to the presence of a riser pole (since this pole can not be located on SCE Property). Construction of an underground crossing will be complicated due to the presence of existing utilities such as gas, water, and sewer that are currently installed in Live Oak Ave. Traffic disturbance will be greatly increased with the underground crossing option, requiring shut down of lanes for numerous days (or even weeks). Maintenance of the existing utilities and road surface on and in Live Oak Ave will be more difficult with the presence of an underground crossing since any excavation would be in proximity to buried energized 220kV transmission line. Despite the crossing being underground, the necessary riser poles contribute to visual clutter just the same as the overhead crossing, though they may be shorter than the overhead crossing approach. An overhead crossing would present minimal increased visual disturbance as there are currently numerous overhead crossings in this area already. The addition of one additional overhead crossing would not present new viewshed disturbances to the public. It is also worth noting that the nearest non-utility infrastructure to this crossing appear to be industrial buildings approximately 0.15 miles away. There are additional commercial properties within 0.5 miles and residential properties outside of 0.5 miles, behind the commercial properties. Visibility of this crossing to residences would be almost non-existent, as a result.
