Procedural backbone · 0.1

Process Crosswalk

The Process Crosswalk for UDO Chapter 3. Maps every development review type the City operates to its decision-maker, its statutory basis in Title 76, chapter 25, MCA, the public role at first instance, the review timeline, and the appeal path. This is the single most-used reference in the procedures chapter — staff use it to route an application, applicants use it to see what they are in for, and it is the table that makes the chapter-25 review posture legible at a glance. Promoted to its own structural element within Chapter 3, following the Missoula Article 2.2 model.

What the crosswalk does

Title 76, chapter 25 reorganized development review around a single distinction: legislative actions, where the public participates through hearings before the decision, versus administrative actions, where the public participated when the land use plan and the implementing regulations were adopted and the application is now reviewed against those adopted standards. 76-25-102(3)(d) states the legislative intent directly — the statute is built to allow streamlined administrative review of site-specific development applications. The Process Crosswalk makes that structure visible: it sorts every review type Helena operates into legislative or administrative, shows the public role each carries, and shows where an appeal goes. Phase 1 already moved Helena's review processes onto this footing; the crosswalk is the reference that holds the whole picture in one place.

The impact path is the hinge

The single most important mechanic in the administrative family is the impact determination. Every administrative development and subdivision review runs through the same fork: is the application in substantial compliance with the adopted regulations AND were all its impacts previously analyzed when the plan and regulations were adopted? If yes — the clean path — the Planning Administrator decides on a short clock with notice but no comment period (76-25-305(4); 76-25-408(7)). If the application is in substantial compliance but may produce new or significantly increased impacts not previously analyzed — the impact path — the statute requires additional data, additional analysis, and a 15-business-day public comment period before the decision (76-25-305(5); 76-25-408(8)). If the application is NOT in substantial compliance, it is not an administrative application at all — the applicant must seek a regulation or map amendment under 76-25-304 and follow the legislative path (76-25-305(7)). The crosswalk shows this fork on every administrative row because it is the same fork every time.

Where the City Engineer sits

Consistent with Chapter 1 (11-1-9.D), the City Engineer is not a decision-maker in this crosswalk. Department review — Public Works, Transportation Systems, Fire, and other agencies — is a step within the administrative review timeline, not a separate decision. The Planning Administrator decides; departments review and comment. The engineering and fire-code requirements that department review checks against are established outside this Title; the crosswalk shows department review as a timeline step, not as an authority.

Two clocks

Helena's process documents run on two clocks and the crosswalk preserves the distinction because applicants live by it: 'working days' for completeness review and department review steps, 'business days' for the statutory decision deadlines and the appeal windows. Title 76, chapter 25 uses 'business days' throughout. Where a Helena process document states a step in working days, the crosswalk records it in working days; where it states a statutory deadline in business days, the crosswalk records business days.

The two families of review

Legislative. Actions that adopt or amend the regulations themselves — the zoning map, the zoning text, the subdivision regulations, the land use plan. Decided by the governing body on the recommendation of the Planning Commission, after public notice and participation under 76-25-106 and a public hearing. Challenged in district court under 76-25-503(2), within 30 days of the resolution or ordinance. There is no administrative appeal of a legislative action — the public's participation IS the hearing process, and the recourse is the courthouse.

Administrative. Actions that apply the already-adopted regulations to a specific site or application — zoning compliance permits, conditional use permits, variances, site-specific development review, subdivision review. Decided by the Planning Administrator. The public's role at first instance is notice; a written comment period attaches only where the application triggers the new-or-increased-impacts path (76-25-305(5) for development, 76-25-408(8) for subdivision). Appealed under 76-25-503 — the two-tier de novo path, Planning Administrator to Planning Commission to governing body, then district court.

Administrative reviews

PX-ZCP · Administrative

Zoning compliance permit

What it is
The ministerial baseline. Confirms that proposed development complies with all applicable provisions of the UDO — use, form, dimensional, parking, the lot. The default review every development passes through unless it is routed to a more specific review type below.
Decision-maker
Planning Administrator
Statutory basis
76-25-305(3) — zoning compliance permits and other ministerial permits may be issued by the Planning Administrator without further review or analysis by the governing body, except as provided in 76-25-503. 76-25-103(24) — ministerial permit, decided on objective standards involving little or no personal judgment.
Public role
None at first instance for the clean path. Notice and a 15-business-day comment period if the impact path is triggered (76-25-305(5)).
Impact fork
Yes — runs the substantial-compliance and impact determination like every administrative development review. A genuinely ministerial permit on the clean path is the common case; the impact path is available but rarely reached for a simple compliance permit.
Timeline
Not separately fixed by a Helena process document — the zoning compliance permit is the routine over-the-counter or short-cycle review. The statutory decision posture is the 76-25-305(4) clean-path decision.
Appeal
76-25-503 two-tier de novo — Planning Administrator to Planning Commission (15 business days to appeal), to governing body (15 business days), to district court (30 calendar days, exhaustion required).
Current Helena process
Helena issues zoning compliance permits administratively. Phase 1's conformance amendments already put the routine permit on the ministerial footing.
What the UDO does with it
Carried forward. The UDO's contribution is to define the zoning compliance permit as a named term (Chapter 1) and to state plainly that it is the default — an application is a zoning compliance permit review unless the use tables or the procedures chapter route it to CUP, site-specific review, or subdivision review.
PX-CUP · Administrative

Conditional use permit (CUP)

What it is
Review of a use marked 'CUP' in the use tables — a use permitted in the zoning district subject to a site-and-operation compatibility review against the 11-3-4(B) criteria. The CUP is a ministerial process: the criteria function as objective standards the use is reviewed against, not discretionary factors staff weigh.
Decision-maker
Planning Administrator
Statutory basis
76-25-305 — the CUP runs the site-development review posture. 76-25-103(24) — the ministerial-permit framing (objective standards, little or no personal judgment) is what requires the 11-3-4(B) criteria to be drafted as objective standards. Appeal under 76-25-503.
Public role
Clean path (no-impact finding): public notice — webpage, letters to adjacent owners, sign posted on site — and concurrent department review, no comment period. Impact path: a 15-business-day written comment period, limited to the new or significantly increased impacts identified.
Impact fork
Yes — this is the defining mechanic. After completeness, the Planning Administrator makes the impact determination: substantial compliance with the zoning regulations and map, and whether the use produces new or significantly increased impacts not previously analyzed. No-impact finding routes to concurrent notice and department review; impact finding routes to applicant data collection, additional analysis, and the 15-business-day comment period.
Timeline
Per the City's April 2026 CUP Process: completeness review 5 working days; impact determination 5 working days. Clean path — 10-working-day concurrent department review; Planning Administrator written decision within 25 business days of completeness. Impact path — 15-business-day comment period, then 10-working-day department review; Planning Administrator written decision within 40 business days of completeness.
Appeal
76-25-503 two-tier de novo — written appeal within 15 business days, first to the Planning Commission, then to the City Commission, then district court. Appeals are not automatic; they occur only if filed.
Current Helena process
Helena's adopted April 2026 CUP Process already operates the CUP exactly as described — a ministerial process under 76-25-305, Planning Administrator decision against the 11-3-4(B) criteria, the impact fork, appeal to the Planning Commission. The CUP Checklist (updated April 2026) ties the review to '11-3-3 City Code' for completeness and '11-3-4 City Code' for criteria.
What the UDO does with it
Carried forward into the consolidated procedures chapter. The CUP is not a divergence from Title 76, chapter 25 that the memo has to defend — the City's adopted practice already runs it as a conformant ministerial process. The residual drafting task: express the 11-3-4(B) criteria as objective standards a use either meets or does not. Criterion 12 (public comment collection) is dropped — the 76-25-305(5) impact path supplies the public-comment mechanism, so a separate criterion collecting comment is redundant. The 'what it is not' provision tracked in the working file belongs in this chapter: a CUP may not be used to deny a use because the use category is unpopular where the UDO has already made it conditionally available in the zoning district.
PX-VAR · Administrative

Variance (zoning and subdivision)

What it is
Relief from a land or building form design standard, or from a subdivision design and improvement standard, granted against the five criteria in 76-25-502(4). One consolidated process handles both zoning and subdivision variances.
Decision-maker
Planning Administrator. The decision is final.
Statutory basis
76-25-502 — variances. 76-25-502(2): the application must be for relief from land or building form design standards or subdivision design and improvement standards. 76-25-502(3): considered before or in conjunction with the related zoning permit or subdivision approval. 76-25-502(4): the five criteria, all of which must be met. 76-25-502(6): reviewed and determined by the Planning Administrator, decision is final, no further action except as provided in 76-25-503.
Public role
Public notice — webpage, letters to adjacent owners, sign posted on site — and concurrent department review. The Variance Process does not run a separate impact fork; notice and department review are concurrent on a single track.
Impact fork
No. The variance process as Helena runs it is a single track — completeness, then concurrent public notice and department review, then decision. The five 76-25-502(4) criteria are the substantive test; there is no separate new-or-increased-impacts branch the way there is for CUP and site-specific review.
Timeline
Per the City's April 2026 Variance Process: completeness review 5 working days; 10-working-day concurrent public notice and department review; Planning Administrator written decision within 20 business days of completeness.
Appeal
76-25-503 two-tier de novo — written appeal within 15 business days, first to the Planning Commission, then to the City Commission, then district court. Note 76-25-502(6) makes the Planning Administrator's decision final, and 76-25-503(3)(a) expressly lists the approval or denial of a variance among the appealable final administrative decisions — so 'final' means final at the administrative-decision stage, with the 76-25-503 appeal as the defined recourse.
Current Helena process
Helena's adopted April 2026 Variance Process runs exactly this — one consolidated zoning-and-subdivision variance, Planning Administrator decision within 20 business days, appeal to the Planning Commission. The current Title 11 Chapter 5 Board of Adjustment is already retired in practice.
What the UDO does with it
Carried forward. The Board of Adjustment is retired — settled, both in the working file and in the City's current practice. The variance lives in the relief chapter in the 7+ block; its procedure is drawn here in Chapter 3. There is no separate 'administrative adjustment' tier — 76-25-502 establishes the variance as the relief mechanism, full stop. The criteria carried into the relief chapter are the verified 76-25-502(4) criteria, not the prior Board-of-Adjustment hardship test. One Phase 1 cleanup item lands here: the double variance track left in Title 12 12-2-4 — the stray retained City-Commission-hearing language is removed, because 76-25-502(6) settles the decision at the Planning Administrator.
PX-SSD · Administrative

Site-specific development review (commercial, multi-unit residential, preliminary subdivision plat)

What it is
The ministerial review for commercial development, multi-unit residential development, and preliminary subdivision plats. Helena's process document treats these three under one 'Site Specific Development Process' because they share the same procedural skeleton — completeness, impact fork, decision — even though the substantive standards differ.
Decision-maker
Planning Administrator — for the preliminary plat and for the commercial / multi-unit residential site-specific decision. NOTE: final plat approval is NOT administrative — see PX-SUB-FINAL.
Statutory basis
76-25-305 effective July 1, 2027 — for commercial and multi-unit residential site development. 76-25-408 effective July 1, 2027 — for the preliminary plat (76-25-408(7) clean path, 76-25-408(8) impact path). Appeal under 76-25-503.
Public role
Clean path: public notice — webpage, letters to adjacent owners, sign posted on site — and concurrent department review, no comment period. Impact path: a 15-business-day written comment period limited to the new or significantly increased impacts.
Impact fork
Yes — the same fork as the CUP. After completeness, the Planning Administrator makes the impact determination: substantial compliance with the zoning regulations and map (and, for a subdivision, the subdivision regulations), and whether new or significantly increased impacts not previously analyzed are present. 76-25-408(7) and (8) mirror 76-25-305(4) and (5) almost exactly for the subdivision case.
Timeline
Per the City's April 2026 Site Specific Development Process: completeness review 20 working days; impact determination 5 working days. Clean path — 10-working-day concurrent department review; Planning Administrator written decision within 15 business days of completeness. Impact path — 15-business-day comment period, then 15-working-day department review; Planning Administrator written decision within 30 business days of the end of the comment period. The statute is consistent: 76-25-408(7)(c) sets the clean-path preliminary plat decision at no later than 15 business days from completeness; 76-25-408(9) sets the impact-path decision at within 30 business days of the end of the comment period.
Appeal
76-25-503 two-tier de novo — written appeal within 15 business days, first to the Planning Commission, then to the City Commission, then district court. 76-25-408(13) makes the Planning Administrator's preliminary plat decision final, with 76-25-503 as the recourse; 76-25-503(3)(a) expressly lists preliminary plat among the appealable decisions.
Current Helena process
Helena's adopted April 2026 Site Specific Development Process runs all three review types — commercial, multi-unit residential 3+, and preliminary subdivision plat — on this shared skeleton. Pre-application consultation is required for subdivision applications, recommended for the others.
What the UDO does with it
Carried forward. The reorganization's contribution: the UDO names the shared procedural skeleton once, in Chapter 3, and the substantive standards live in their own chapters — commercial and multi-unit residential form in Chapter 4 and the CSR chapter, subdivision design in Chapter 5. Chapter 3 owns the procedure; the substance is distributed. This is the Missoula subdivision-procedure split applied: common mechanics here, subdivision-specific submittal and design in Chapter 5.
PX-CSR · Administrative

Commercial site review (CSR)

What it is
Site plan review for commercial development and multi-unit residential development, conducted prior to or concurrent with building permit review. Helena separated site review from building permit review so site design issues are resolved before the building permit clock runs. CSR is procedurally a site-specific development review (PX-SSD) — the CSR chapter carries the submittal detail and the standards-for-review, Chapter 3 carries the procedure.
Decision-maker
Planning Administrator (Planning Division issues the site plan approval).
Statutory basis
76-25-305 — CSR runs the site-development review posture. Appeal under 76-25-503.
Public role
As for site-specific development review (PX-SSD): notice on the clean path, the 15-business-day comment period on the impact path.
Impact fork
Yes — CSR is a site-specific development review and runs the same impact fork.
Timeline
CSR follows the Site Specific Development Process timeline (PX-SSD). The Commercial Site Review document (November 5, 2025) describes the review-process steps — pre-development consultation, formal submission, interdepartmental review, comment-and-revision cycle, final approval — and confirms a building permit is not issued until CSR concludes successfully, though the two reviews may run concurrently.
Appeal
76-25-503 two-tier de novo — written appeal within 15 business days, Planning Commission then City Commission then district court.
Current Helena process
Phase 1 codified CSR as new Title 11 Chapter 27; it has been operating since December 1, 2025. The Commercial Site Review document sets applicability: all new commercial development; all multi-unit residential development of three or more units; and alterations that increase building size by 25%, change the use, or alter parking or landscaping compliance.
What the UDO does with it
Carried forward as a load-bearing chapter. The reorganization gives CSR a proper structural home and expresses it in the same procedural vocabulary as the rest of the UDO — it is a site-specific development review (PX-SSD) procedurally, so Chapter 3 carries its procedure by reference and the CSR chapter in the 7+ block carries the submittal requirements and the standards for review. CSR is the integration point where Chapter 4 form, Parking, Landscaping, and the Engineering Standards seam all land on an actual project.
PX-EXEMPT · Administrative

Subdivision exemption review

What it is
Review of a claimed exemption from subdivision review — the categories at 76-25-402 (and the related certificate-of-survey exemptions): court-ordered divisions, certain family transfers, retracement, amended plats, and the rest. The review confirms the exemption is genuinely applicable and is not being used to evade subdivision review.
Decision-maker
Planning Administrator (the Director of Community Development or designee) certifies that the exemption is applicable.
Statutory basis
76-25-402 — exemptions to subdivision review. 76-25-408(2) — on receipt of an exemption application with all required materials, the local government shall approve or deny within 20 business days; may not impose conditions except those necessary for survey-requirement compliance under 76-25-412(1); and may require examining-land-surveyor review.
Public role
None. Exemption review is a determination of applicability against the statutory categories, not a discretionary review.
Impact fork
No. An exemption is either applicable or it is not.
Timeline
76-25-408(2)(a): approve or deny within 20 business days of a complete application.
Appeal
76-25-503 — an exemption determination is a final administrative land use decision (76-25-503(3)(a) reaches interpretations of land use regulations and the like). Two-tier de novo.
Current Helena process
Helena's Exempt Subdivision Plat Checklist (updated April 2026) runs this — the Director of Community Development or designee certifies the exemption, the checklist cites 76-25-402, and it carries the statutory anti-evasion language: an exemption may not be used for the purpose of evading subdivision review, city zoning regulations, or installation of infrastructure.
What the UDO does with it
Carried forward. The exemption categories and the anti-evasion rule live in the subdivision chapter (Chapter 5); the procedural skeleton — 20-business-day determination, no conditions except survey compliance — is stated here in Chapter 3. One note for the criteria: 76-25-404(1)(e) requires the subdivision regulations to state the criteria the Planning Administrator uses to decide whether a proposed exemption is an attempt to evade the chapter — that criteria set is a Chapter 5 drafting item.
PX-SUB-PRELIM · Administrative

Preliminary plat (major subdivision)

What it is
Review of the preliminary plat for a subdivision that is not an administrative minor subdivision and not exempt. The preliminary plat decision is administrative — this is the chapter-25 change that Phase 1 already implemented. See PX-SSD for the shared procedural skeleton; this row records the subdivision-specific statutory detail.
Decision-maker
Planning Administrator. 76-25-408(13): the decision is final.
Statutory basis
76-25-408 effective July 1, 2027 — the full preliminary plat review procedure. 76-25-408(7) clean path, 76-25-408(8) impact path, 76-25-408(9) impact-path decision deadline, 76-25-408(10) the findings the decision rests on, 76-25-408(11) the written-decision content requirements, 76-25-408(12) delivery and appeal-information requirements, 76-25-408(13) finality. 76-25-409 — effect of preliminary plat approval.
Public role
Clean path: notice, no comment period. Impact path: 15-business-day written comment period (76-25-408(8)(a)(iii)).
Impact fork
Yes — 76-25-408(7) and (8), mirroring 76-25-305(4) and (5).
Timeline
Clean path: written decision no later than 15 business days from completeness (76-25-408(7)(c)). Impact path: written decision within 30 business days of the end of the 15-business-day comment period (76-25-408(9)). Completeness determination: 20 business days (76-25-408(5)(a)). Optional pre-application review: within 30 business days of a written request (76-25-408(1)). A subdivision application is considered received on the date it is delivered with the review fee (76-25-408(4)).
Appeal
76-25-503 two-tier de novo. 76-25-503(3)(a) expressly lists preliminary plat among the appealable final administrative decisions.
Current Helena process
Helena's Site Specific Development Process treats the preliminary subdivision plat as one of the three site-specific review types, on the shared skeleton. Phase 1 already rewrote subdivision procedures to this fully administrative model and deleted the old hearing apparatus.
What the UDO does with it
Carried forward. The procedural skeleton is in Chapter 3 (shared with PX-SSD); the subdivision-specific submittal requirements, the findings content, the phasing-plan provisions, and the effect-of-approval rules are in Chapter 5. 76-25-408(14) — any change to an approved preliminary plat that increases the lot count or redesigns six or more lots requires an amended plat following the full procedure — is a Chapter 5 drafting item.
PX-SUB-FINAL · Administrative

Final plat (major subdivision)

What it is
Review and approval of the final plat — the recordable drawing that conforms to the approved preliminary plat and its conditions. This is the one place in the otherwise-administrative subdivision track where the decision is NOT the Planning Administrator's.
Decision-maker
The governing body — the City Commission — approves or denies the final plat. The Planning Administrator makes the completeness determination; the governing body makes the approval decision. This is a verified, deliberate feature of the statute, not a Helena choice.
Statutory basis
76-25-410 effective July 1, 2027. 76-25-410(4): within 10 business days of receipt, the Planning Administrator determines whether the final plat contains the required information. 76-25-410(5): once the Planning Administrator's completeness determination is made, the GOVERNING BODY shall review and approve or deny the final plat within 20 business days. 76-25-410(1): the submittal requirements — conformance to the preliminary plat decision and conditions, a plat meeting the 76-25-412(1) survey requirements, and the county treasurer's certification that taxes and special assessments are paid.
Public role
None at the final plat stage — the final plat is a conformance check against the already-approved preliminary plat. The public's role attached at the preliminary plat stage.
Impact fork
No. Final plat review is a conformance determination — does the final plat match the approved preliminary plat and satisfy its conditions, the survey requirements, and the tax certification.
Timeline
76-25-410(4): Planning Administrator completeness determination within 10 business days of receipt. 76-25-410(5): governing body approval or denial within 20 business days of the completeness determination. 76-25-410(6): the subdivider and the governing body may mutually agree to extend the review periods. A final plat application is considered received on the date it is delivered with the review fee (76-25-410(3)).
Appeal
76-25-503 two-tier de novo. 76-25-503(3)(a) expressly lists final plat among the appealable final administrative land use decisions — so even though the governing body makes the final plat decision, it is reviewed as a final administrative land use decision under 76-25-503, not challenged only in district court the way a legislative action is. NOTE this is a point worth getting right in the chapter text: a governing-body final plat decision is appealable through 76-25-503; a governing-body legislative action (a rezoning, a text amendment) is challenged in district court under 76-25-503(2). Same body, two different recourse paths, depending on whether the action is administrative or legislative.
Current Helena process
Helena's process documents show preliminary plat as administrative and route final plat to the City Commission, consistent with 76-25-410(5).
What the UDO does with it
Carried forward — and the crosswalk should make this prominent because it is a predictable confusion point. Final plat approval at the City Commission is the rule for major subdivisions; it is required by 76-25-410(5). The administrative minor subdivision (PX-SUB-MINOR) is the exception — administrative end-to-end including final plat. The Chapter 3 text needs to state both clearly so staff and applicants do not assume 'subdivision review is administrative' means 'final plat is administrative' — it does not, except for the minor subdivision.
PX-SUB-MINOR · Administrative

Administrative minor subdivision

What it is
The carve-out: small, low-impact divisions handled administratively end-to-end, including final plat, without City Commission action. This is the exception to PX-SUB-FINAL. It runs on its own statutory authority and — importantly — its own appeal path.
Decision-maker
The Community Development Director or designated representative issues a written determination of approval, conditional approval, or denial.
Statutory basis
76-3-609 — the administrative minor subdivision review path. NOTE the statutory basis is Title 76, chapter 3, not chapter 25. This is the deliberate, narrow exception that coexists with 76-25-105(4)'s general rule that a chapter-25 jurisdiction is not subject to Title 76, chapter 3. 76-3-620 — the written-determination requirement Helena's checklist cites.
Public role
Notice to immediately adjoining property owners and contract-for-deed purchasers of immediately adjoining property. Not a comment period — a notice that triggers a specific objection-and-review right (see appeal).
Impact fork
No — the administrative minor subdivision is a defined category of small, low-impact divisions; it does not run the new-or-increased-impacts fork.
Timeline
Per Helena's Administrative Minor Subdivision Checklist (updated April 2026): within 30 working days of a determination that the application contains the required elements and sufficient information, the Community Development Director or designee issues the written determination, pursuant to 76-3-620.
Appeal
SEPARATE TRACK — this is the second of Helena's two subdivision appeal paths and the crosswalk must show it distinctly. If a noticed party objects to the Director's decision, the party may request IN WRITING TO THE CITY MANAGER that the decision be appealed, per 76-3-609. The City Commission then has 15 working days from receipt of the request to review the decision and make a final determination. The standard of review: the City Commission shall sustain the Director's decision, based on the whole record, unless the decision was arbitrary, capricious, or unlawful. This is NOT the 76-25-503 two-tier de novo path — it is a single-tier, deferential-standard review by the City Commission, initiated through the City Manager.
Current Helena process
Helena's Administrative Minor Subdivision Checklist (updated April 2026) runs exactly this — the 30-working-day written determination under 76-3-620, the notice to immediately adjoining owners, and the 76-3-609 appeal to the City Commission via the City Manager under the arbitrary/capricious/unlawful standard. Phase 1 rebuilt Title 12 Chapter 5 around this process.
What the UDO does with it
Carried forward — and this is the row that makes the 'dual subdivision appeal track' real. The Chapter 3 consolidated appeals provision must describe BOTH tracks: the 76-25-503 two-tier de novo path for most decisions, and this 76-3-609 single-tier City-Commission-review path for the administrative minor subdivision. The working file flags this as the detail most likely to be drawn wrong. The memo should explain — not assume away — why a Title 76, chapter 3 mechanism survives in a chapter-25 ordinance: 76-25-105(4) makes chapter 3 generally inapplicable, but the administrative minor subdivision under 76-3-609 is a specific, deliberate retention that Phase 1 confirmed.

Legislative actions

PX-MAP · Legislative

Zoning map amendment (zone change and prezone)

What it is
An amendment to the Official Zoning Map — a zone change for a parcel already in the City, or a prezone assigning a zoning district to a parcel proposed for annexation (the prezone takes effect on annexation). Also the path an applicant must take when a proposed development is NOT in substantial compliance with the zoning regulations or map (76-25-305(7)).
Decision-maker
The governing body — the City Commission — adopts, adopts with revisions, or rejects, on the recommendation of the Planning Commission.
Statutory basis
76-25-304 — adoption and amendment of zoning regulations. 76-25-304(1)(b): an amendment may be initiated by majority vote of the governing body, by petition of at least 15% of the electors, or by a property owner in connection with a land use application. 76-25-304(2): before recommending, the Planning Commission provides public notice and participation under 76-25-106, accepts and responds to public comment, and makes the preliminary substantial-compliance determination. 76-25-304(2)(d) and (3): the Planning Commission preliminarily determines whether the amendment produces new or increased impacts, and if so the City collects additional data and analysis. 76-25-304(4): the Planning Commission makes a final recommendation. 76-25-304(5): after public notice and participation, the governing body may adopt, adopt with revisions, or reject — and 76-25-304(5)(c) provides the governing body may not condition a map amendment.
Public role
Full legislative public participation under 76-25-106 — dissemination of draft documents, written and verbal comment, public meetings after effective notice, online access, and an analysis of and response to comments. Public hearings before the Planning Commission and the governing body.
Impact fork
A legislative analogue of the impact fork exists: 76-25-304(2)(d) has the Planning Commission preliminarily determine whether the amendment produces new or increased impacts beyond what the land use plan assessment analyzed, and 76-25-304(3) requires additional data and analysis if so. Helena's Zoning Map Amendment Process implements this as a possible second Planning Commission hearing — the 'impact finding hearing.'
Timeline
Per Helena's April 2026 Zoning Map Amendment Process: completeness review 5 working days; applications taken on a set schedule, not rolling. Public hearing notice published, 10-working-day concurrent department review. Planning Commission preliminary determination hearing; if a new-or-increased-impact finding is made, a public comment period runs to a second Planning Commission hearing (the impact finding hearing, on the 2nd-Tuesday meeting cycle). Planning Commission recommendation forwarded to the City Commission. City Commission public hearing within 30 business days of the Planning Commission recommendation.
Appeal
No administrative appeal. A challenge to the adoption of or amendment to a zoning map is presented to the district court within 30 days of the resolution or ordinance, under 76-25-503(2). Helena's process document states this as appeal 'directly to' court — the public's participation is the hearing process; the recourse is judicial.
Current Helena process
Helena's adopted April 2026 Zoning Map Amendment Process runs the two-hearing Planning Commission structure (preliminary determination, then impact finding if warranted) and the City Commission hearing within 30 business days of the recommendation. Prezone applications run concurrently with annexation (see PX-ANNEX).
What the UDO does with it
Carried forward into the procedures chapter. The map amendment is also the procedure for amending the A-grid and B-grid — the grid is a layer of the Official Zoning Map, so a change to grid membership runs through the zoning map amendment process. This is the structural decision recorded in the working file. The substantive review criteria the City Commission applies are a Chapter 2 / Chapter 3 drafting item; 76-25-304(2)(c) lists what the Planning Commission's substantial-compliance determination must consider.
PX-TEXT · Legislative

Zoning text amendment / subdivision regulation amendment

What it is
An amendment to the text of the UDO itself — the zoning regulations or the subdivision regulations. Distinct from a map amendment: this changes the rules, not the district boundaries.
Decision-maker
The governing body — the City Commission — adopts, adopts with revisions, or rejects, on the recommendation of the Planning Commission.
Statutory basis
76-25-304 — for zoning regulation text. 76-25-403 — for subdivision regulation amendments (the governing body adopts or amends subdivision regulations only after consideration by and on the recommendation of the Planning Commission). 76-25-104(3)(a) — the Planning Commission's review-and-recommend role covers the zoning regulations and map, the subdivision regulations, and any other legislative land use document the governing body designates.
Public role
Full legislative public participation under 76-25-106 — the same posture as a map amendment. Public hearings before the Planning Commission and the governing body.
Impact fork
Not applicable in the site-specific sense. The legislative impact analysis is the substantial-compliance and impact assessment the Planning Commission performs under 76-25-304 against the land use plan.
Timeline
Not separately fixed by a Helena process document the way the map amendment is — the text amendment follows the legislative cycle: Planning Commission notice, hearing, and recommendation under 76-25-106 and 76-25-304 / 76-25-403, then the City Commission hearing and action.
Appeal
No administrative appeal. A challenge to the adoption of or amendment to a zoning regulation or subdivision regulation is presented to the district court within 30 days of the resolution or ordinance, under 76-25-503(2).
Current Helena process
Helena adopts and amends Title 11 and Title 12 by ordinance on Planning Commission recommendation — this is how Phase 1 itself was adopted in April 2026.
What the UDO does with it
Carried forward. The UDO's contribution is to state the text-amendment procedure once, covering both the zoning and subdivision regulations, since they are now one instrument. The adopting ordinance for the UDO is itself a legislative action of this type.
PX-ANNEX · Legislative

Annexation

What it is
Annexation of territory into the City. Reviewed in conjunction with the prezone that assigns the territory its zoning district. Helena runs annexation by petition under Title 7, chapter 2, part 46, MCA, concurrently with the prezone map amendment.
Decision-maker
The governing body — the City Commission — holds a public hearing and considers a Resolution of Intention to annex; a final annexation request returns to the City Commission before the property is annexed.
Statutory basis
76-25-306 — zoning and annexation: the City reviews and considers a proposed annexation in conjunction with the prezone adopted under 76-25-301(1)(c), following the procedures of 76-25-305; and 76-25-306(2) — the joint public process satisfies the notice and public hearing requirements for annexation under Title 7, chapter 2, parts 42 through 47. The annexation itself proceeds under Title 7, chapter 2, part 46.
Public role
Public hearing before the City Commission. Public hearing notice — Community Development webpage, letters to adjacent owners, legal notice in the Independent Record, sign posted on site. Per 76-25-306(2), the joint annexation-and-prezone process satisfies the Title 7 annexation notice and hearing requirements — one process, not two.
Impact fork
The prezone runs the legislative impact analysis through the map amendment process (PX-MAP). The annexation review is conducted in conjunction with that.
Timeline
Per Helena's April 2026 Annexation by Petition Process: completeness review 5 working days; 20-working-day department review; the City Commission public hearing is set on the conclusion of the Planning Commission prezone recommendation; the City Commission hearing on the Resolution of Intention follows, typically about 4 weeks from the Planning Commission prezone recommendation. A final annexation request returns to the City Commission.
Appeal
The prezone, as a zoning map amendment, is challenged in district court under 76-25-503(2). The annexation proceeds under Title 7, chapter 2, part 46.
Current Helena process
Helena's adopted April 2026 Annexation by Petition Process runs annexation concurrently with the prezone — a property not already prezoned must submit a prezone application with the annexation petition. The process is administered under Title 7, chapter 2, part 46; Title 11; and Title 76, chapter 25.
What the UDO does with it
Carried forward. The UDO's contribution is in Chapter 1 (11-1-5.D, prezoning and annexation coordination) and here in Chapter 3 — the procedures chapter states the prezone-and-annexation concurrency. The UDO does not re-codify Title 7 annexation law; it states how the prezone map amendment coordinates with it, per 76-25-306.

Appeals structure

TRACK_1_THE_CHAPTER_25_APPEAL

76-25-503 two-tier de novo appeal

Applies to
Every final administrative land use decision except the administrative minor subdivision. 76-25-503(3)(a) lists the reach expressly: approval or denial of a zoning permit, preliminary plat or final plat, imposition of a condition on a zoning permit or plat, approval or denial of a variance, or interpretation of land use regulations or the map. This is the path for PX-ZCP, PX-CUP, PX-VAR, PX-SSD, PX-CSR, PX-EXEMPT, PX-SUB-PRELIM, and PX-SUB-FINAL.
Structure
Two tiers, both de novo. Tier 1: the applicant or any aggrieved person appeals the Planning Administrator's decision to the Planning Commission, in writing, within 15 business days, stating the facts and all grounds. The Planning Commission holds a public hearing and hears the appeal de novo — it is not bound by the decision appealed, but the appeal is limited to the issues raised, and the appellant bears the burden of proving the appealed decision was made in error. Tier 2: the applicant, the Planning Administrator, or any aggrieved person appeals the Planning Commission's decision to the governing body, in writing, within 15 business days; the governing body also hears de novo on the same terms. Then: district court — a person must exhaust the administrative appeal before going to court, and the petition is filed within 30 calendar days of the governing body's written decision, limited to the issues raised on administrative appeal.
Statutory basis
76-25-503(3) (tier 1), 76-25-503(4) (tier 2), 76-25-503(5) (district court and exhaustion), 76-25-503(6) (the arbitrary/capricious/unlawful standard on the administrative record), 76-25-503(7) (Title 2, chapter 4 — the Montana Administrative Procedure Act — does not apply).
Notes
['76-25-503(4)(a) lets the PLANNING ADMINISTRATOR appeal a Planning Commission decision to the governing body — worth capturing in the chapter text, because it means the appeal path is not only applicant-driven.', 'Notice of the appeal must be published as provided in 7-1-2121 or 7-1-4127, as applicable (76-25-503(3)(c)(ii) and (4)(c)(ii)).', '76-25-503(6): every final land use decision must be based on the administrative record as a whole and must be sustained unless arbitrary, capricious, or unlawful — that is the district court standard, applied after the two de novo administrative tiers.', "Appeals are not automatic — they occur only if filed. Helena's process documents state this on every review type."]
TRACK_2_THE_MINOR_SUBDIVISION_APPEAL

76-3-609 City Commission review

Applies to
Only the administrative minor subdivision (PX-SUB-MINOR).
Structure
Single tier, deferential standard. A property owner of record immediately adjoining the subject property, or a contract-for-deed purchaser of immediately adjoining property, is given notice of the pending application. If a noticed party objects to the Director's decision, the party may request in writing to the City Manager that the decision be appealed. The City Commission has 15 working days from receipt of the request to review the decision and make a final determination. The City Commission shall sustain the Director's decision, based on the whole record, unless the decision was arbitrary, capricious, or unlawful.
Statutory basis
76-3-609 — a deliberate, narrow retention of a Title 76, chapter 3 mechanism, coexisting with 76-25-105(4)'s general rule that a chapter-25 jurisdiction is not subject to chapter 3.
Notes
['This is NOT de novo and NOT two-tier. It is one review, by the City Commission, on the whole record, under the arbitrary/capricious/unlawful standard — the standard 76-25-503 reserves for the district court stage is the standard the City Commission applies here at first review.', 'It is initiated through the City Manager, not through the Planning Commission.', 'The Chapter 3 consolidated appeals provision must describe this track distinctly and must explain its statutory basis — a reader who knows 76-25-105(4) will reasonably ask why a chapter 3 mechanism is here, and the answer is that 76-3-609 is a specific retained path that Phase 1 confirmed.']
TRACK_3_LEGISLATIVE_CHALLENGE

Direct district court challenge

Applies to
Legislative actions — PX-MAP, PX-TEXT, and the prezone component of PX-ANNEX.
Structure
No administrative appeal. A petition setting forth the basis for the challenge is presented to the district court within 30 days of the resolution or ordinance adopted by the governing body.
Statutory basis
76-25-503(2).
Notes
['The distinction the chapter text must hold: the SAME body — the City Commission — can produce an administratively-appealable decision (a final plat, under 76-25-503(3)(a)) and a directly-court-challengeable decision (a rezoning, under 76-25-503(2)). The recourse path follows the nature of the action, administrative versus legislative, not the identity of the decision-maker.']
