Flagstaff advances three-year forest preservation pilot despite concerns over vague developer standards

Flagstaff Planners Grapple with Subjectivity and Fire Science in Forest Preservation Pilot, Defer Vote to Late May Public Hearing

The Flagstaff Planning and Zoning Commission spent Wednesday evening (May 14, 2025) interrogating the philosophical and practical foundations of a proposed three-year pilot program to overhaul how the city preserves trees during development within its 35-year-old Resource Protection Overlay. The text amendment (PZ250088) would replace a decades-old point-based system keyed to tree diameter with a new framework anchored in LIDAR imagery, tree height, fire science, and staff judgment—a shift that several commissioners warned could create enforcement ambiguities, unintended incentives for tree removal, and loopholes if not carefully calibrated.

No vote was taken; the item advances to a public hearing on May 28, 2025. But the evening's discussion revealed deep commissioner anxiety about subjective language, the absence of numerical preservation thresholds, and the trade-offs between fire safety and forest character that will likely resurface when the public weighs in.

Key Speeches

"So this is what I think the fire department and what Neil has tried so hard to get through my head is that I wanted to come to you with the solution in hand. But that would be the wrong approach because often what I think in the forefront is not where we get to at the end run." — Tiffany Antel, Zoning Code Manager

"I just felt it was looser and more subjective and I wondered if that creates too many unintended consequences and loopholes." — Mary Norton, Commissioner

"We might make a mistake, but we—what do we have to lose on a couple of properties at this point? I mean, we're not clear-cutting ever." — Tiffany Antel

"The resource protection overlay is a very important part of making and has made Flagstaff what it is. And we need to keep that theme involved that Flagstaff is part of our environment, part of a forest environment and not on top of it." — Nat White, public commenter

Timeline

• Staff presentation: Tiffany Antel, Flagstaff Zoning Code Manager, outlined the pilot program's purpose, process, and proposed code language, emphasizing integration of modern LIDAR technology, fire science from the 2024 Forest Management Plan, and improved collaboration between Planning and Fire departments on resource decisions. Staff acknowledged the current diameter-at-breast-height (DBH) system is outdated and conflicts with wildfire risk reduction science.

• Commissioner questions (ongoing): Joshua Maher asked whether the pilot would expedite development and whether staff has capacity; Mary Norton requested specific percentage thresholds for high-value tree preservation rather than subjective standards ("greatest extent feasible," "as determined by staff"); commissioners raised concerns about greenfield vs. infill site treatment, enforcement of early-termination provisions, and conflict resolution when developers and staff disagree on tree retention.

• Staff clarification: Antel explained that the pilot is voluntary, applies only to forest resources (not slope or other RPO requirements), and includes contractual forest resource agreements with termination clauses if applicants fail to meet purpose and goals. No percentage thresholds are built in because staff wants to develop standards through pilot experience rather than "handcuff ourselves" with arbitrary numbers. She committed to regular updates and field trips to commissioners.

• Public comment: One speaker, Nat White (1120 North Rockidge), a long-time Flagstaff resident (56 years), provided historical context on the Resource Protection Overlay (established in response to the clearcut and grading of the West Walmart area in 1987–1989). He cited successful integrated developments (Ponderosa Trails, Equestrian Estates) and supported the pilot as using "less crude and better tools" to achieve the same conservation goals.

• Council discussion: Discussion focused on the meaning of "greatest extent feasible," whether it creates loopholes, whether developers might be incentivized to enter the pilot to remove more trees than current code allows, how termination disputes would be resolved, whether the program treats greenfield and infill sites appropriately, and what "high-value tree" means in practice.

• Vote: None; item continues to public hearing May 28, 2025.

Opposition

Number of speakers against: None at this discussion meeting (one public comment supporting; no organized opposition present).

Main concerns raised by commissioners (not traditional opposition, but substantive reservations):

1. Subjective language creates enforcement risk: Mary Norton repeatedly objected to phrases like "greatest extent feasible" and "as determined by staff," warning that loose language may enable loopholes and create unintended consequences. She noted that staff changes over time, making reliance on staff discretion risky.

2. No specific preservation thresholds: Both Norton and Joshua Maher expressed discomfort with the absence of a minimum percentage of high-value trees to be preserved. Norton asked if a developer-unfavorable site could be required to preserve, say, 50% of identified high-value trees; Antel demurred, saying percentages might "handcuff" adaptive site-by-site decision-making.

3. Developers may remove more trees under pilot than under current code: Norton and Maher both flagged concern that the pilot could paradoxically incentivize developers to participate because they might achieve higher tree removal rates. Antel acknowledged this was "definitely going to be the outcome" on many sites due to current overstocking but emphasized that removal would be guided by fire science, not developer preference.

4. Greenfield vs. infill disparity unclear: Commissioner Mary Norton asked whether greenfield and infill sites should be treated differently and whether a single standard can serve both. Antel acknowledged the tension but argued that the pilot will help answer it; she privately favored infill sites and cited the Pinole and Lone Tree property as a potential pilot candidate.

5. Conflict resolution mechanism ambiguous: If staff and a developer disagree on how many high-value trees to preserve, Mary Norton asked how the conflict is resolved. Antel replied that staff can terminate the agreement and require the developer to use the original code, but the vagueness of that remedy troubled commissioners.

6. Insurance and fire safety claims insufficiently documented: CJ Lucky raised the intersection of fire insurance costs and affordable housing, noting that fire insurance is expensive and people are having policies dropped—suggesting the pilot's purported insurance benefits may be overstated or unproven. Antel deferred detail to Neil Chapman (Flagstaff Fire Department), who was absent.

7. Early termination of pilot program possible but unspecified: Commissioner Mary Norton asked whether the pilot could be terminated early if it is not working; Antel confirmed this is possible via code amendment but did not specify an evaluation threshold or timeline.

Most compelling commissioner arguments:

• Mary Norton's repeated emphasis on subjectivity: "It's just ambiguous to me to say 'determined by staff.' I don't know how that could be better stated." This framing—that loose language is administratively indefensible regardless of good intent—resonated with Maher.
• Joshua Maher's observation that regular updates and transparency on pilot outcomes would help commissioners trust a process lacking hard numerical standards.
• Nat White's historical argument (supported by Mary Norton's acknowledgment) that Flagstaff's forest character is a core community asset and that the overlay itself—crude as it was—prevented catastrophic clearcuts; changing it risks repeating past mistakes.

Organized groups: None present.

Support

Number of speakers in favor: One public comment (Nat White) explicitly supportive; several commissioners (Joshua Maher, CJ Lucky) expressed qualified support conditional on staff updates and pilot transparency.

Main arguments in support:

1. Fire science and ecosystem health require evolution: Tiffany Antel and Neil Chapman's (absent but referenced) fire science expertise supports moving from static DBH-based standards to dynamic forest density and health assessments aligned with the 2024 Forest Management Plan. Many residential properties in the overlay are overstocked with trees and create fire hazard; the pilot allows site-specific optimization.

2. Current code conflicts with best available science: Staff noted that current standards (50% preservation for residential, 30% for open space) are outdated and don't align with fire resilience science. The pilot enables a science-based reset.

3. Voluntary nature and termination clause mitigate risk: Developers can opt out; staff can terminate agreements if goals are not met. This allows experimentation with limited downside.

4. Historical success of integrated development: Nat White cited Ponderosa Trails and Equestrian Estates as examples of developments that worked well within the overlay, demonstrating that the goal of "building within the forest, not on top of it" is achievable. He argued the overlay succeeded or failed based on developer willingness to adapt, not the standards themselves.

5. Improved inter-departmental collaboration: The pilot requires Planning and Fire to work together early and continuously, rather than sequentially (fire thinning, then planning). This integration is expected to produce better outcomes than either department acting alone.

6. Technology and data enable better decisions: LIDAR imagery, tree height data, and basil area density calculations offer richer information than DBH alone. Staff and developers can jointly identify high-value tree clusters and optimize site plans around them.

7. Infill and greenfield both benefit, though differently: While greenfield sites may eventually be treated with different standards, infill sites developed 20–30 years ago under the old overlay, never thinned and containing unhealthy tree pockets, stand to benefit from targeted high-value tree preservation and forest health improvements.

Project Details

• Case number: PZ250088

• Applicant / developer: N/A (this is a citywide text amendment to the Flagstaff Zoning Code, not a specific project application). However, staff identified two potential pilot participants: (1) Pinole and Lone Tree property (HR zone, 20-year-old rezoning case, marked for thinning, threatened by Lone Tree Road widening); (2) Equestrian Estates area.

• Attorney: None named; Tiffany Antel (Zoning Code Manager) presented on behalf of the Planning Department and Flagstaff Fire Department. Neil Chapman (Flagstaff Fire Department) was absent but is the co-sponsor.

• Location / address: Citywide; all properties within the Resource Protection Overlay (RPO).

• APN (if stated): Not stated in transcript.

• Current zoning → Proposed zoning: Text amendment only; no rezoning. Current code: Resource Protection Overlay standards with 50% forest resource preservation for residential, 30% for open space, based on DBH-point calculations. Proposed: Three-year pilot program replacing point-based system with staff assessment of "high-value resources" (oldest, largest, most fire-resistant trees) using LIDAR, tree height, site inspection, and health characteristics. No fixed percentage thresholds; preservation required "to the greatest extent feasible as determined by staff."

• Density / units / square footage: Not specified (this is a process/standards amendment, not a specific development).

• Changes from previous version (if reconsideration): This is the initial public discussion of the pilot program; no prior version was reviewed at this meeting.

Vote Breakdown

Final: No vote taken. Item continued to public hearing May 28, 2025.

Yes / No / Abstentions / Absences: N/A.

Outcome & Next Steps

Decision: The Planning and Zoning Commission did not take a vote on PZ250088 at the May 14, 2025 discussion meeting. The item is scheduled for a public hearing on Wednesday, May 28, 2025, at which time community input will be solicited and the commission may consider a recommendation to City Council.

Conditions / Modifications: None adopted at this meeting. However, staff committed to:

• Developing specific numerical standards (percentages, tree density targets, basil area baselines) during the pilot program based on site-by-site experience, rather than prescribing them in advance.
• Providing regular updates to the commission on pilot projects, including what decisions were made and why.
• Offering field trips to commissioners to observe pilot sites and thinning/development outcomes before and after.
• Consulting with a local LIDAR/forestry software consultant to prepare prototype models showing current code outcomes vs. forest management plan desired conditions.

What comes next:

1. Public hearing May 28, 2025, with testimony and possible commission vote on a recommendation to City Council.

2. If advanced by the commission, the text amendment will go to City Council for consideration (timeline not specified in transcript).

3. Assuming adoption, the three-year pilot program would begin (likely July 2025 based on Antel's reference to "assuming adoption in July") and accept voluntary forest resource agreements from developers.

4. Staff will actively recruit pilot participants, starting with properties identified as good candidates (Pinole/Lone Tree, Equestrian Estates area) and any others with willing developers and early-stage conceptual plans.

5. At the end of three years, staff will present findings and recommend permanent code revisions (or termination of the pilot) based on pilot outcomes.

Controversies & Context

Subjectivity and enforcement:

Mary Norton's core concern—that phrases like "greatest extent feasible" and "as determined by staff" introduce dangerous subjective language—cuts to the heart of administrative law and code enforceability. She is right that loose language invites disputes and staff inconsistency. Antel's counter-argument—that prescribing percentages now would "handcuff" adaptive decision-making and may be based on bad assumptions—is philosophically coherent but administratively risky. The commission left this tension unresolved, deferring to the pilot to generate empirical evidence of what percentage preservation is feasible for different site conditions. This is pragmatic but leaves significant discretion in staff hands.

Developer incentive to over-remove trees:

Norton and Maher both surfaced the concern that the pilot could incentivize developers to participate because it allows higher tree removal rates than the current code. Antel acknowledged this is "definitely going to be the outcome" on many sites (which are currently overstocked) but argued that removal would be guided by fire science and forest health, not developer preference. However, the absence of a minimum preservation threshold means developers have no hard floor—only staff judgment and a termination threat if goals are missed. This creates a fundamental asymmetry: if staff and developer disagree, the developer can walk away and use the old code (which guarantees 50% preservation); staff can terminate the agreement, but that does not prevent the developer from using the old code either. The incentive structure thus slightly favors developers who enter early in the process and are willing to negotiate.

Fire safety vs. forest character:

Mary Norton eloquently captured the emotional core of Flagstaff's debate: the fear that modernizing the overlay in the name of fire safety will result in visible deforestation that alters the city's iconic forest character. She cited the contrast between Smokerise (thinned, fewer ponderosas visible) and Christmas Tree (denser forest) across Highway 89, asking whether she would see the same pattern repeated under the pilot. Antel responded that healthy forests and fire-adapted neighborhoods are compatible, that "an unhealthy forest" may look beautiful but is less valuable ecologically, and that the goal is to make smarter preservation decisions, not clear-cut. Nat White's historical argument—that the overlay was born from the outcry over the West Walmart clearcut and exists to encourage building within the forest, not on top of it—anchored the conversation in Flagstaff's regulatory DNA. But the balance between these goals is delicate; the pilot will either validate the thesis that smart thinning and fire-adapted development can coexist with visual forest retention, or it will produce visible examples of thinned sites that community members perceive as deforestation.

Greenfield vs. infill:

A subsidiary debate emerged over whether large greenfield sites south of Interstate 40 (where much of Flagstaff's future growth is expected) should be treated differently from infill sites in established neighborhoods. Mary Norton suggested they should be; Antel seemed to agree but noted that current code already treats open space zones (30% preservation) differently from residential (50%), a friction the pilot aims to resolve. The tension remains unresolved: are site-specific standards truly more equitable and effective, or do they just hide ad-hoc decision-making under a veneer of fire science?

Lack of public process and developer input:

Mary Norton asked whether any local developers were consulted during drafting; Antel replied that the pilot is "really the brainchild of the fire department and the planning department," with minimal developer input. However, staff has had preliminary conversations with at least two developers post-City Council presentation and is in early recruitment. This raises questions about transparency: Is this a bottom-up standards reform driven by planning professionals and fire experts, or a top-down pilot that may face pushback from a development community that has not yet internalized its rationale?

Enforcement and penalties:

CJ Lucky flagged enforcement as critical and asked for hard penalties; Antel noted that tree removal violations carry $1,000–$1,200 per tree fines and cited a past case (Olive Garden area) where penalties were imposed (though one commenter questioned whether they exceeded the developer's profit). The historical example of a developer who cut trees without authorization, was fined, and allegedly sold the land to another developer casts doubt on whether penalties alone deter violations. The pilot will need robust monitoring and enforcement to avoid becoming a permission structure for early removal under the guise of fire science.

Consultant involvement:

Staff mentioned engaging Headquarters Economics (a nonprofit Forest Service–funded group specializing in wildfire-resilient zoning codes) and a local LIDAR/forestry software consultant. These experts are expected to provide prototype models and peer review but do not attend the commission meeting. Their role in validating or questioning staff assumptions is unclear.

Insurance claims:

Antel repeatedly punted detailed questions about homeowner insurance and fire insurance to Neil Chapman (Fire Department). CJ Lucky's point—that fire insurance costs are rising and people are losing coverage—raises the question of whether the pilot's promised insurance benefits are real or aspirational. This is a politically sensitive intersection of affordability, fire safety, and code design that deserves explicit analysis.

Summary

The Flagstaff Planning and Zoning Commission's discussion of PZ250088 highlighted the deep tension between modernizing tree preservation standards in response to fire science and maintaining the city's forest character and regulatory predictability. Commissioners Mary Norton and Joshua Maher pushed back substantively on subjective language and the absence of numerical thresholds, warning that vague standards may create loopholes and inconsistency. Zoning Code Manager Tiffany Antel framed the pilot as a necessary experiment: trying to develop context-specific standards through real projects rather than prescribing one-size-fits-all percentages that may be inappropriate for varied site conditions. Public commenter Nat White provided crucial historical validation, recalling Flagstaff's overlay as a response to catastrophic clearcuts and arguing that the goal—building within the forest—remains sound, only the tools are evolving.

No vote was taken; the item advances to a public hearing May 28, 2025. The unresolved tension—between flexibility and predictability, between fire safety and forest character, between trust in staff expertise and the need for objective standards—will likely surface again when the community weighs in. Staff's commitment to transparency, field trips, and regular updates may build confidence, but only if pilot projects demonstrably preserve forest character while improving fire resilience. If early pilot sites appear over-thinned or generate community outcry, the pilot may be terminated before three years elapse. The outcome will likely shape Flagstaff's relationship to its forest for the next three decades.
