Mesa advances West Mesa transit plan; battery storage setback debate deferred to Monday vote
Study session featured significant debate over battery energy storage setback requirements and approval of comprehensive transit-oriented development plan for West Mesa corridor, with one council member voting against BES ordinance due to safety concerns while another opposed the 1,000-foot setback as economically damaging.
Battery Energy Storage Setback and West Mesa Transit Plan Dominate Study Session as Council Grapples with Competing Safety and Economic Concerns
Mesa City Council convened for a study session on December 4, 2025, to review the agenda for Monday's council meeting. The session featured extensive debate over two major planning items: a proposed zoning text amendment to allow battery energy storage systems in industrial zones with a 1,000-foot residential setback, and the Mesa Connected transit-oriented development plan for a five-mile West Mesa corridor. The study session revealed sharp disagreement over the BES setback requirement and broad support (with caveats) for the comprehensive transit plan.
Battery Energy Storage System Setback: The Core Conflict
Key Speeches
"I appreciate your comments and I did listen to the study session at the council meeting that I missed. I did as much research as I can. I looked at peer cities. Los Angeles is one to 300 feet. San Francisco 2 to 500. Houston 3 to 500. Miami 3 to 500. Phoenix 2 to 300. Las Vegas 3 to 500. Charlotte, North Carolina 2 to 300. Atlanta, Georgia 3 to 500 feet. I can't find anybody any cities that required a mile separation… The only city or area that I can find that prohibits them altogether was in Hawaii in Kauaii in particular because of the fire risk." — Council Member Jen Duff
"I spent 20 years in hazardous materials. I've been a tox medicic. I know the byproducts of combustion when these things burn. I've written an article on them. I've fought battery fires. I've been part of the NFPA process… There is no quantitative number on how far away from residential or other uses this must be because there hasn't been large-scale testing. There's been component testing, but a large scale and fire testing has not been done." — Council Member Goforth
"The energy is already there is being wasted… this is the cheapest fastest energy available for economic development… SRP has no way to replace that energy in order to prepare… 600 megawatts of clean energy that we're expecting and that is they said limit our economic growth and grid reliability in this area. 400 foot setback achieves the goal. A thousand foot setback does not." — Council Member Jen Duff, quoting SRP concerns
Timeline
- Staff recommendation (original): 400 feet, modeled on data-center setback precedent and aligned with NFPA guidelines.
- Planning & Zoning Board recommendation: Returned to 400 feet after staff presented the 1,000-foot option.
- Staff final recommendation: Remained at 1,000 feet, based on stakeholder feedback during public meetings.
- Council discussion: Jen Duff presented research showing peer cities ranging from 100 feet to 500 feet, with no U.S. city requiring 1,000 feet except Hawaii (which prohibits BES entirely). Council Member Goforth cited hazardous-materials experience, lack of large-scale fire testing, and safety concerns. Both acknowledged the need for BES but disagreed sharply on distance.
- Vote: Scheduled for Monday, December 8.
Opposition (Council Member Duff's Position)
- Main arguments:
- No peer-city precedent: Research across Los Angeles, San Francisco, Houston, Miami, Phoenix, Las Vegas, Charlotte, Atlanta, and New York City showed setbacks ranging from 100 to 500 feet; no city required 1,000 feet.
- Economic harm: 1,000 feet creates "wasted land" with no contributing factor to the city or energy demands; equivalent to three football fields of separation.
- Conflict with pending projects: A multifamily development adjacent to an existing BES site on Signal View had approved a 400-foot setback and will lose capacity under the 1,000-foot rule.
- Grid reliability impact: SRP wrote a letter stating 1,000-foot setback will eliminate 600 MW of clean energy, undermine Mesa's economic development goals, and increase costs for residents and businesses.
- Industry standards: American Planning Association, NFPA guidelines, and energy developers recommend 100 to 500 feet, not 1,000 feet.
- Energy infrastructure proximity: BES systems must be located close to substations to operate; 1,000-foot setback makes GI and HRI zoning impractical for deployment.
- Renewable-energy precedent: States with more renewables and battery storage have lower power costs; BES is the cheapest, fastest energy available for economic development.
Support (Council Member Goforth's Position)
- Main arguments:
- Safety precedent: Santa Cruz County requires 1,000 feet; Kern County a quarter mile; Alameda County Virginia 5,000 feet; New York State proposed 1,000 feet for BES over 5 MW; California proposed 3,200 feet; multiple California and New York municipalities (Monterey, Salano County, Marian County, Yorktown, Carmel, Oyster Bay) have 1,000-foot or greater setbacks.
- Lack of large-scale testing: Component testing exists but not full-scale fire testing; therefore, conservative setback is warranted.
- Hazardous-materials expertise: Firefighters know the byproducts of lithium-ion battery combustion and rapid fire propagation; chemical composition makes it distinctly hazardous compared to standard house fires.
- Mixed-use zoning concern: The Signal View area represents "a bad zoning scrambled egg" where apartments are being mixed with industrial uses and BES systems.
- Future adaptability: Council can adjust the setback in the future if new evidence emerges or implementation shows problems.
Project Details
- Case number: Not stated in transcript.
- Proposed zoning text amendment: Allow battery energy storage systems in GI (General Industrial) and HRI (Heavy Research/Industrial) zones with 1,000-foot separation from residential uses.
- Current legal status: BES systems currently not permitted in any zoning district under a zoning interpretation; this amendment would make them a permitted use under certain circumstances.
- Pending applications: Two pre-applications and one site (Signal View) currently under construction could become legally conforming or procedurally legal-conforming uses if the ordinance is approved.
- Signal View multifamily impact: Residential-zoned parcel within approximately 450 feet of the Signal View BES site; 1,000-foot requirement would impact placement of the first battery system and reduce site capacity.
- Substation dependency: BES systems must be within approximately one mile (per Council Member Goforth) of transformer stations to be cost-effective; distances beyond that require state ACC line-sighting committee review.
Procedural and Interpretive Questions
City Attorney Jim clarified that if the ordinance fails on Monday, BES will not be allowed in Mesa; staff would return in January or February with alternative options. If the 1,000-foot setback is approved, council can later amend the ordinance to reduce the setback, but doing so would require a full public-notice and Planning & Zoning Board process.
Planning Director Mary noted that two pending applications are positioned to become "procedurally legal-conforming uses" (a category recently adopted by the council) if this ordinance passes. This distinction allows sites that met standards at approval time but later became non-conforming due to a zoning interpretation to be treated as conforming for financing and development purposes. Council Member Goforth requested a map showing industrial zoning, residential zoning, and existing SRP substations to visualize the actual impact of the 1,000-foot requirement across the city, particularly in District 3 (her district). Staff indicated this analysis would be completed but noted that not all substations have the capacity to support BES systems.
Mesa Connected Transit-Oriented Development Plan
Key Speeches
"I'm of course very supported. I think this is really a boost um to the area and it's going to make it more cohesive and the connected plan pulling together West Mesa… Building a place not a project and I think this could be very powerful for West Mesa… This is a long time in coming for West Mesa." — Council Member Jen Duff
"For us in West Mesa, I think I go back to why this corridor… faster projected growth two times faster than citywide this area, right?… The need to create um options for the future is the reason why this quarter makes sense… We can't maintain the status quo in this area, right?… More people even before the announcement of the theme park district… we need options for people to travel and have placemaking opportunities across this area." — Council Member Francisco Heredia
Timeline
- Grant award and project start: Federal Transit Administration grant received; planning process began in 2023.
- Public engagement: Ongoing throughout three phases (Explore, Envision, Planning). Approximately 60,000 postcards sent in Envision phase; 455 responses from online surveys and open houses (0.63% response rate from 72,000 corridor residents). Pop-up events, focus groups with business owners and special-interest groups (transportation advocates), MCC student government meetings, and online surveys conducted.
- Study session presentation: Rachel Phillips, Assistant Planning Director, walked council through the five-chapter plan, 11 transit nodes, and implementation strategy.

- Final vote: January 12, 2026 (as stated for final approval).
- Grant deadline: February 2026 (all final paperwork must be submitted through Phoenix, which administers the regional FTA grant).
Project Details
- Applicant / Funder: City of Mesa Planning Department; Federal Transit Administration (FTA) grant.
- Location / Corridor: Five-mile transit route from Mesa Riverview (north) along Dobson Avenue, Southern Avenue, and Country Club Drive to downtown/light rail connection (south). Half-mile buffer on either side of the route. Spans West Mesa from Riverview to downtown, touching major activity centers: Cub Stadium, Mesa Riverview, Banner Desert Medical Center, MCC, future Fiesta Mall redevelopment, and downtown.
- Population: 72,000 residents within corridor; young, diverse, lower-income population; high percentage of renters and multifamily housing.
- Transit ridership: 27% of Mesa's overall transit ridership occurs within this corridor (highest in city).
- Existing conditions: Dobson Road is city's busiest corridor with highest crash rate; limited room for road expansion; organic transit-oriented development already occurring (Asian District, Riverview improvements, Sprouts opening at School and Southern).
Plan Structure and Key Components
The plan consists of five chapters:
- Introduction: Purpose, planning process, public engagement, organization.
- Existing conditions overview: Population, economy, mobility, housing data (detailed in appendices).
- Vision and guiding principles: Five guiding principles and corridor-wide strategies to create walkable communities, mixed housing, business support, revitalization, infill, adaptive reuse, expanded mobility, and enhanced public spaces.
- Transit node planning: Classification of 11 nodes by intensity (neighborhood, urban, regional); transit node evaluation based on TOD characteristics, redevelopment potential, and transit readiness; individual profiles for each node.
- Implementation and action plan: Specific programs and text amendments to support the vision.
Transit Node Classifications
- Neighborhood transit nodes: Compact, community-oriented hubs with small-scale retail, office, and small-to-medium density housing (duplexes, townhomes, apartments). Provide everyday goods and services.
- Urban transit nodes: Medium intensity, mixed-use hubs with employment uses alongside retail and medium-to-higher density housing (mid-rise apartments, condos). Walk-everywhere experience.
- Regional transit nodes: Primary economic, cultural, and entertainment hubs (Riverview, future Fiesta Mall site) with large-format office, employment centers, destination retail, entertainment, and dense housing mix.
Support
Council Members Jen Duff, Francisco Heredia, and Goforth expressed strong support, emphasizing:
- Jen Duff: Plan consolidates West Mesa assets (Asian District with 80+ restaurants, Banner Desert Medical Center, MCC, Riverview, Fiesta redevelopment, upcoming Sprouts) into a cohesive economic engine. Context-sensitive node approach avoids one-size-fits-all development. Captures $7B (Tempe) and $12B (Phoenix) in return-on-investment from similar TOD plans. Addresses Dobson Road congestion and crashes through planned infill rather than road expansion. Boosts sales-tax revenue critical to city funding.
- Francisco Heredia: Area already experiencing organic 2x faster-than-citywide growth. Infill development of 4,000+ units at Fiesta Mall requires transportation alternatives; status quo is unsustainable. Small businesses in Asian District and Riverview need momentum; planning provides strategic framework. Tempe's Rule to Marketplace project will add 50,000+ people; Mesa must provide attractive retail and dining options to capture spending.
- Goforth: Existing corridor characteristics (young, mobile, high transit ridership) are already occurring organically. Plan steps back, protects existing character, enables continued private investment through simplified zoning and design standards. City can capitalize on what is already happening.
Opposition and Concerns
Council Member Taylor, newly elected, raised concerns about:
- Low community-engagement response rate: 455 respondents from 72,000 residents = 0.63% feedback rate on a major multi-year planning effort. Mailer response rate: 0.08% (455 responses from ~58,000 postcards).
- Income disparity: Corridor average income $20,000 below Mesa citywide median; unclear if plan benefits current low-income residents or attracts higher-income infill.
- "Build it and they will come" concern: Plan assumes private investment will follow; no costing analysis of city implementation (demolition programs, small-business support, design guidelines).
- Unresolved transit mode: Plan does not specify whether future transit will be light rail, streetcar (Tempe-Mesa Streetcar feasibility study mentioned), bus rapid transit, or other; potential impacts on road usage unclear. Concerns about dedicated right-of-way and road-capacity impacts.
- Implementation costs: No analysis provided of city financial obligations or investments required to activate plan.
- Timing pressure: January deadline creates pressure to vote on inadequate understanding; requested delay to conduct more research and engage District 2 constituents (who are not directly affected by West Mesa plan).
Clarifications Provided by Staff and Council
On community engagement: Jen Duff and Francisco Heredia have represented West Mesa for 7 years; planning was informed by continuous constituent feedback. Outreach was diverse (pop-ups, focus groups, online surveys, social media, mailers) but voluntary participation is always low in planning projects. Responses received were largely positive from businesses and residents.
On binding effect: Plan does not bind city to financial obligations or investments. All action-plan items (text amendments, design standards, demolition programs, small-business support) require future council approval. Implementation is phased and evolutionary.
On zoning overlay: Proposed approach is an optional, opt-in overlay (similar to form-based code) rather than mandatory rezoning. Property owners can choose to adopt new development standards if they offer advantages; no mandatory rezoning.
On grant funding: Two prior studies (Fiesta District Alternative Analysis and Tempe-Mesa Streetcar Feasibility Study, both completed 2021) were funded by Proposition 400 (regional sales tax for transportation), not local taxes. Prop 400 sunsets December 31, 2025; Proposition 479 (passed November 2024) will succeed it.
On living document: Plan is intentionally flexible. Council will revisit it as conditions change and will approve each implementation step separately. Specific concerns (e.g., Council Member Summers's dislike of billboard overlay expansion) can be discussed when those items come before council.
On action plan: John Giles highlighted examples such as demolition-assistance programs and small-business support as potentially replicable in other parts of the city beyond the corridor.
Vote and Next Steps
Study session vote: Informational; no formal vote recorded. Ordinance to be introduced Monday, December 8; final approval scheduled for January 12, 2026, to meet February 2026 FTA grant close-out deadline (managed through City of Phoenix).
Other Notable Items
Paragrin Data Sharing Platform (Police Department Pilot—Items 7A and 7B)
Deputy Director Pat Phelps and IT Manager Wayne Kuang presented a one-year pilot project to implement the Paragrin data-sharing platform for Mesa Police Department. The system enables integrated searching of records management and CAD data within Mesa and across regional agencies (Tempe, Gilbert, Queen Creek), replacing an aging 10+-year-old system (Crime Tracer/CopLink). Funded by Senate Bill 1735 state grant ($215,800 for year one); no binding obligation for year two. Council Member Taylor questioned data management, encryption, and potential public-records request improvements. Police indicated the system reduces manual searches, automates crime analysis, and provides mobile interface for officers. Monthly cost and year-two funding depend on success and additional state grants. Vote scheduled for Monday; no opposition noted in study session.
Fujifilm Expansion and Rezoning (Item 8B)
Fujifilm facility expansion south of US-24 in industrial area. Company acquiring former ADOT agricultural parcel to be rezoned from agricultural to heavy industrial. Site plan shows new buildings on west side of facility. Project includes 80 new well-paid jobs and is part of PIRATE rail-spur project, which could remove dozens of trucks daily from roads. Design review underway to maximize aesthetic appeal despite OSHA visibility requirements for worker safety. Approved for rezoning and expansion. Council Member Taylor questioned public comments (none recorded due to industrial location outside citizen-notification radius) and aesthetic concerns; Council Member Goforth noted company has worked extensively on design, acknowledging aesthetic challenges but emphasizing economic and transportation benefits.
AWS Data Center with Private Substation (Item 6A)
Amazon Web Services data center under construction in industrial area. Project requires council use permit for private electrical substation to step down voltage for facility operations. SRP substation is adjacent; private substation is needed for applicant's specific requirements. Council Member Taylor questioned the need for separate substation and whether public comments were solicited (none recorded due to industrial location). Planning staff explained this is common infrastructure at other data centers and design review will include screening per city ordinance. Approved.
Crime Lab Regional Services and Reimbursement (Item 5A)
Mesa Crime Laboratory serves four agencies (Mesa, Tempe, Gilbert, Queen Creek) on cost-neutral basis. Forensic Lab Director Kim highlighted dramatic stability improvements since 2012 when the lab became regional. Turnaround times, capacity, and award-winning status improved; prevents smaller agencies from lab closures. Intergovernmental agreements based on anticipated workload; invoiced at year start; monitoring throughout year to manage budget. Agencies absorb costs through intergovernmental payments. Vote scheduled for Monday; no opposition noted.
Duration
- Study session: Approximately 3 hours (no total time stated in transcript).
- BES ordinance discussion: Approximately 1 hour (extensive debate over setbacks, peer-city research, and implementation).
- Mesa Connected presentation and Q&A: Approximately 1.5 hours (comprehensive plan overview, public-engagement rationale, implementation framework, and council member questions).
- eBike code updates: Approximately 1 hour (definitions, city-code changes, safety concerns, enforcement strategy, communication campaign, and council member questions regarding feasibility, enforcement, and parent liability).
- Other items (Paragrin, AWS, Fujifilm, Crime Lab): Combined approximately 30 minutes.
Controversies & Context
Battery Energy Storage Setback Debate
The 1,000-foot residential setback became the focal point of a broader disagreement over how Mesa should balance renewable-energy infrastructure, grid reliability, economic development, and public safety.
Jen Duff argument rested on empirical research: peer cities across the nation have adopted setbacks ranging from 100 to 500 feet; American Planning Association, NFPA (National Fire Protection Association), and industry professionals endorse similar ranges. She argued the 1,000-foot requirement is not supported by any study, incident, or professional standard and makes BES economically unviable for Mesa. SRP's letter underscored this: the proposed setback will eliminate 600 MW of clean energy Mesa is counting on, undermining both grid reliability in high-growth areas and the city's ability to attract advanced-manufacturing businesses that require reliable, affordable power. The conflict with the Signal View multifamily development exemplifies the practical problem: a project already approved with a 400-foot setback will lose capacity if the ordinance passes with 1,000 feet, delaying promised renewable energy supply.
Council Member Goforth's argument emphasized precaution in the absence of full-scale fire-testing data. She cited her 20-year hazardous-materials background, noting that lithium-ion battery combustion produces unique toxic byproducts and rapid fire propagation that differ from standard house fires. She presented evidence from jurisdictions with higher setbacks (Santa Cruz, Kern, Alameda counties in California; New York State proposals; several California and New York municipalities with 1,000-foot to mile-plus requirements). She framed the 1,000-foot setback as reasonable and noted it does not prohibit BES systems in Mesa, only requires greater separation. She also acknowledged the competing concerns about grid reliability and economic development and indicated willingness to revisit the distance if new evidence emerges.
The underlying tension is between precautionary safety (absent complete fire-testing data, wider separation is conservative) and market-driven energy investment (renewables require proximity to substations; excessive separation makes deployment uneconomical and reduces clean-energy availability, driving up costs for residents and forcing reliance on less efficient alternatives).
Mesa Connected Plan: Community Engagement and Implementation Ambiguity
Council Member Taylor's skepticism focused on two issues: the low participation rate in public engagement and the lack of concrete costing and implementation timelines. Her concern is partly procedural (she was not present for years of planning and lacks context) and partly substantive: with 455 responses from 72,000 residents, how representative is the feedback? If 4,000+ units are coming to Fiesta Mall regardless, why is the plan necessary beyond providing advisory guidance?
Staff and supporting council members' response: The plan is not about building; it is about zoning, design standards, and incentive programs (demolition assistance, small-business support) to guide and accelerate private investment. The high organic growth in the corridor, plus the planned Fiesta redevelopment, creates urgency to provide a strategic framework so the city can capture economic benefits and protect existing character through context-sensitive development rather than piecemeal projects. Engagement rates of ~0.6% are normal for planning projects; continuous representation by Jen Duff and Francisco Heredia provides accountability to constituents.
Unresolved questions include: (1) What is the cost to Mesa for demolition assistance and small-business-support programs? (2) Is light rail, streetcar, or bus rapid transit planned, and if so, when and with what impact on right-of-way? (3) Will zoning overlay adoption be voluntary or mandatory? (4) If plan approval binds council to no financial obligations, how will property-owner opt-in for overlay result in streamlined review?
The January 12 vote deadline (FTA grant close-out February 2026) compressed council's timeline. John Giles and City Attorney Jim indicated that staff can continue refining implementation strategies in January if the plan is approved in principle, subject to future text amendments and council votes on specific programs.
Votes
No formal votes were taken during the study session (which is informational). Both the BES ordinance and Mesa Connected plan are scheduled for introduction Monday, December 8, and will return for final votes at later dates (BES on Monday, per Jim's clarification; Mesa Connected on January 12).
