Naming convention by category
res_sf	v1 used lot-size-tier labels (RS-E/RS-5/RS-6/RS-7/RS-D); live UDC per Google snippets uses lot-size-tier letter-codes (R-1A, R-1B, R-1D)
res_mf	v1 used use-type-index with density (RM-12, RM-16); live UDC per Google snippets uses single multifamily code (R-MF)
mu	v1 MU-C; live UDC has form-based DBAC overlay/base hybrid plus PMXD planned mixed-use
com	v1 used use-type-index (NC, CG); live UDC uses intensity-index (C-1, C-2)
ind	v1 used use-type-index (CI, I-L, I-H); live UDC uses single industrial code per snippets (M-1)

Tyler UDC is Euclidean with form-based integration in DBAC (Downtown Business, Arts & Culture) and mixed-use districts. Planned district types (PMXD = Planned Mixed-Use Development, PCD = Planned Commercial Development, PUR = Planned Unit Redevelopment) are available as rezoning paths — hybrid-pd classification reflects their role as discretionary entitlement tools rather than by-right zones.

Worth knowing

DISTRICT ROSTER DISCREPANCY: v1 profile uses RS-E/RS-5/RS-6/RS-7/RS-D/RM-12/RM-16/MU-C/NC/CG/CI/I-L/I-H but Google Search snippets of the live Tyler UDC (codelibrary.amlegal.com/codes/tyler) reference R-1A, R-1B, R-1D, R-MF, C-1, C-2, M-1, PMXD, PCD, PUR, DBAC. v1 codes may be plan-stage aspirational labels from the Tyler 21 comprehensive plan that were not adopted verbatim into the UDC ordinance, or a v1 converter artifact. This is a ≥30% roster change — flagged for full re-extraction on amlegal unblock. Until then, carrying v1 codes and numeric values with explicit under_review notes on the codes themselves. [partial]
Tyler UDC adopted 2018 as a major outcome of the Tyler 21 Comprehensive Plan. Exact adoption ordinance date not retrievable — amlegal Cloudflare gate. [confirmed v1 narrative]
Planned districts PMXD (Planned Mixed-Use Development), PCD (Planned Commercial Development), PUR (Planned Unit Redevelopment) are discretionary rezoning paths — reason for hybrid-pd classification. [confirmed Google snippets]

Overlays

DBAC

Downtown Business, Arts & Culture District (DBAC)

§10-34-area Overlay & Special Purpose Districts — DBAC Downtown Business, Arts & Culture

Downtown Tyler core area — DBAC is both a base district and a form-based overlay layer per Tyler 21 plan. Applies to historic downtown square and adjacent parcels mapped on the Tyler Zoning Map (Chapter 10 §10-11).

height_bonus_ft	15^[18]
far_max	3^[19]
form_based_standards	build-to lines, frontage types, transparency requirements (per Tyler 21 plan and v1 narrative)
what_is_confirmed	DBAC exists as a distinct downtown district in the Tyler UDC (v1 narrative + Google Search snippet: 'Downtown Business, Arts and Culture District (DBAC)').
what_is_missing	Exact subsection citation; height bonus mechanism (by-right vs incentive-based); base-district interaction rules.
citation	§10-34-area Overlay & Special Purpose Districts — section anchor confirmed via Google snippet harvest 2026-04-19/2026-04-24

COR

Corridor / Gateway Overlay

COR

§10-34-area Overlay & Special Purpose Districts — Corridor/Gateway

Major corridor and gateway areas — Loop 323, Broadway, SSW Loop 323, Troup Highway, and other entry corridors into Tyler. Corridor-specific design standards apply per mapped overlay boundary.

regulated_metrics	sign height, landscape buffer width, facade material, parking placement (typical TX corridor overlay scope)
what_is_confirmed	Corridor overlay concept present in v1 roster and KNOWN_OVERLAYS.
what_is_missing	Exact subsection citation; specific corridor geography list; design parameter values (buffer widths, sign heights, material requirements).
citation	§10-34-area Overlay & Special Purpose Districts — section anchor confirmed via Google snippet harvest

Floodplain Overlay (FP-1 Floodway / FP-2 Fringe)

§10-34-area Overlay & Special Purpose Districts — Floodplain (FP-1/FP-2); Tyler municipal floodplain management ordinance (separate chapter); FEMA NFIP for Smith County

FEMA FIRM Special Flood Hazard Area (SFHA) mapped within Tyler city limits. FP-1 = floodway (prohibited most development); FP-2 = flood fringe (construction allowed with BFE + freeboard).

federal_overlay_refs	FEMA NFIP SFHA — Tyler (Smith County, TX)
zones_regulated	Floodway (FP-1); Flood Fringe (FP-2)
freeboard_ft	1^[20]
no_rise_required	Floodway no-rise certification per 44 CFR §60.3(d)
what_is_confirmed	Floodplain overlay exists (v1 roster) and is federally required under NFIP participation. FP-1/FP-2 two-tier structure documented in v1.
what_is_missing	Exact subsection citation; municipal freeboard exact value (1 vs 2 ft); substantial improvement threshold.
citation	§10-34-area Overlay & Special Purpose Districts (zoning overlay reference); FEMA NFIP for substantive standards

Historic District — HD (Downtown Historic + Brick Street District)

§10-34-area Overlay & Special Purpose Districts — Historic District (HD)

Locally-designated historic districts in Tyler. Known components: Downtown Historic District (original courthouse square, early-20th-century commercial/civic), Brick Street District (historic brick-paved residential streets). Design review board (Historic Preservation Board) approval required for exterior alterations, new construction, and demolition in mapped districts.

review_authority	Historic Preservation Board (HPB)
components	Downtown Historic District (courthouse square); Brick Street District
regulated_actions	exterior alterations, new construction, demolition, signage in mapped districts; certificate of appropriateness required
what_is_confirmed	Tyler has locally-designated historic districts (v1 narrative references downtown historic district); KNOWN_OVERLAYS='HD' confirmed by orchestrator.
what_is_missing	Exact subsection citation; district boundaries; HPB composition and procedural standards; design guideline parameters.
citation	§10-34-area Overlay & Special Purpose Districts — section anchor confirmed via Google snippet harvest

Airport Overlay — Tyler Pounds Regional Airport (KTYR)

§10-34-area Overlay & Special Purpose Districts (municipal AP overlay if formalized); FAA Part 77 (federal layer applies regardless)

FAA Part 77 imaginary surfaces around Tyler Pounds Regional Airport (KTYR), ~4 miles northwest of downtown Tyler. Part 77 primary, approach, transitional, and horizontal surfaces constrain building heights along approach corridors.

federal_overlay_refs	FAA Part 77 surfaces — Tyler Pounds Regional Airport (KTYR)
airport	Tyler Pounds Regional Airport (KTYR), ~4 mi NW of downtown
applicable_surfaces	Primary, Approach, Transitional, Horizontal (14 CFR Part 77)
what_is_confirmed	Tyler Pounds Regional Airport (KTYR) exists and operates commercial service; FAA Part 77 surfaces apply as a matter of federal law.
what_is_missing	Confirmation of municipal AP overlay codification (vs sole reliance on federal Part 77); height-cap values within Part 77 surfaces per municipal ordinance (if any).
citation	§10-34-area Overlay & Special Purpose Districts (municipal layer pending verification); 14 CFR Part 77 (federal layer)

NOT_FOUND_TOD

TOD / Transit Overlay

TOD

n/a — not codified in Tyler UDC per v1 review and orchestrator KNOWN_OVERLAYS scan

status	not_found
search_performed	Reviewed v1 overlay roster (DT, COR, FP, HD) — no TOD overlay present. Tyler has no passenger rail service and operates only local bus (Tyler Transit). No TOD overlay expected in a bus-only city of ~110k. Google Search snippets referencing §10-34 overlay/special-purpose districts did not mention TOD. amlegal access blocked — cannot verify via § search, but absence from v1 is consistent with no TOD overlay existing.
citation	§10-34-area Overlay & Special Purpose Districts table-of-contents scan — no TOD entry surfaced via Google snippets

NOT_FOUND_ENV

Environmental Overlay (aquifer / riparian / steep slope / wetland buffer)

ENV

n/a — not codified as a standalone environmental overlay in Tyler UDC per v1 review

status	not_found
search_performed	No standalone environmental overlay identified in v1 roster (v1 listed only DT/COR/FP/HD). Tyler's environmental constraints are routed through FP (floodplain) for hydrology; aquifer/steep-slope/wetland overlays typical of Hill Country cities (Austin, San Antonio) are not expected in East Texas piney woods. Tyler does have tree protection via a separate ordinance (historically a 'tree ordinance') but that is code-wide, not a zoning overlay.
citation	§10-34-area Overlay & Special Purpose Districts table-of-contents scan — no ENV entry surfaced

NOT_FOUND_AH

Affordable Housing Bonus Overlay

n/a — no local AH bonus overlay documented in Tyler UDC per v1 review

status	not_found
search_performed	No local AH bonus overlay documented in v1 roster or narrative. Texas has no statewide density bonus law comparable to CA SDBL; local bonus programs rare in mid-size East Texas cities.
citation	§10-34-area Overlay & Special Purpose Districts table-of-contents scan — no AH entry surfaced

NOT_APPLICABLE_AICUZ

Military / AICUZ Overlay

AICUZ

n/a — no active military installation in or adjacent to Tyler

status	not_applicable
reason	No active military installation in or adjacent to Tyler. Tyler Pounds Regional Airport is civilian (KTYR). No AICUZ study zone applies. Nearest military airspace (Barksdale AFB, Shreveport LA) is ~100 mi east — no Tyler parcels within AICUZ.
citation	Federal DoD AICUZ program inventory — no Tyler-area installation; not applicable

State preemptions

TX SB 15applies

Qualifying condition

SB 15 (small-lot deregulation) applies statewide to lots ≤4,000 sf; no population or county threshold. Tyler is subject per-parcel to setback, parking, height, and FAR waivers on qualifying small lots. Of Tyler's residential districts, R-1D (small-lot SF per Google snippet roster) and any PMXD/PUR small-lot subdivision could include qualifying lots. v1 RS-7 (~7,000 sf min) and similar tier districts do not produce ≤4,000 sf lots by-right but assemblage/replatting can. City retains authority over use restrictions and life safety.

Source

Texas SB 15 (88th Legislature) statute text; zoning/us/texas/preemptions.json#tx-sb15-small-lot.

Effect

On lots ≤4,000 sf: city setback, parking ratio, height, and FAR regulations are waived or limited per SB 15 schedule.

Non-applicable laws (4)

TX SB 840does_not_apply

Qualifying condition

SB 840 requires BOTH (a) city population ≥ 150,000 AND (b) county population ≥ 300,000 (conjunctive per zoning/us/texas/preemptions.json trigger_predicate). Tyler city population = 107,405 (2020 Decennial Census) and 109,651 (Census Bureau Population Estimates Program vintage 2024). Smith County population = 230,221 (2020 Decennial Census) and 239,175 (2024 PEP). City pop 109,651 < 150,000 threshold — FAILS city gate (0.73× threshold). County pop 239,175 < 300,000 threshold — FAILS county gate (0.80× threshold). BOTH gates fail by margin: SB 840 does NOT apply to Tyler.

Source

U.S. Census Bureau 2020 Decennial Census (Tyler city FIPS 4874144; Smith County TX FIPS 48423) + 2024 PEP estimates. Texas SB 840 statute text from capitol.texas.gov.

Effect

No preemption — Tyler retains full local control over MF use allowance, density, height, setback, and parking on commercial/office/retail/warehouse/MU parcels.

TX HB 2127does_not_apply

Qualifying condition

HB 2127 (Texas Regulatory Consistency Act) preempts municipal ordinances in fields covered by specific state codes. Zoning authority under Texas Local Government Code Ch. 211 is NOT an enumerated preempted field under HB 2127. Texas courts (2024 district-court ruling) treated zoning as carved out from HB 2127 field preemption. Documented for completeness.

Source

TX Local Gov't Code Ch. 211; HB 2127 enumerated fields list.

Effect

None on Tyler UDC (Chapter 10).

TX HB 3699does_not_apply

Qualifying condition

HB 3699 prohibits cities from banning short-term rentals in residential zones. Tyler's STR regulations (where applicable) sit outside Chapter 10 zoning per typical Texas practice; HB 3699's anti-prohibition mandate is not triggered as a preemption of base zoning.

Source

TX HB 3699 (2023) statute text.

Effect

None on UDC base/overlay districts.

TX ADU preemptiondoes_not_apply

Qualifying condition

Texas has no statewide ADU preemption statute analogous to California GC §66411.7/66411.8. Local Tyler UDC accessory-use rules (§10-79 area, accessory dwelling allowances) govern ADU permissibility, dimensional standards, and lot-size eligibility.

Source

Texas 88th and 89th Legislature regular and special sessions; no enacted ADU preemption bill identified.

Effect

None — local Tyler §10-79-area accessory provisions govern exclusively.

Wayback Machine (web.archive.org) is referenced as a retrieval mechanism for the primary amlegal source, not as a content authority. Smith County GIS map server is a secondary cross-reference, not a code source. (Google snippet result mentioned Zoneomics but it is NOT cited anywhere in the profile.)
confidence tags full form	passed	All 13 dimensional standard `c` fields carry full-form section-area citations: residential standards use p§10-23-area, mixed-use uses p§10-27-area, commercial uses p§10-27-area, industrial uses p§10-31-area. Each district carries a top-level `confidence: p§10-x-area` matching the section anchor confirmed via Google snippet harvest. Section anchors (§10-23 Residential Dimensional, §10-27 Commercial/MU Dimensional, §10-31 Industrial Dimensional, §10-34 Overlay & Special Purpose, §10-79 Accessory Use Conditions) are the authoritative live-UDC anchors per snippet evidence; per-section verbatim text remains pending direct amlegal retrieval (Cloudflare gate). Pattern matches fort-worth-tx p§4.x-area precedent for partial confirmations.

preempt section city specific	passed	state_preemptions_applicable[] contains 5 per-law TX entries (SB 840, SB 15, HB 2127, HB 3699, ADU-none). SB 840 carries city-specific qualifying_condition_checked with primary numeric inputs: Tyler pop 107,405 (2020 Decennial) and 109,651 (2024 PEP); Smith County pop 230,221 (2020 Decennial) and 239,175 (2024 PEP); explicit threshold comparison (city 0.73×, county 0.80×) — determines applies=false (BOTH conjunctive gates fail). SB 15 carries per-parcel-conditional applicability with Tyler-specific district reasoning (R-1D and PMXD/PUR small-lot contexts). HB 2127, HB 3699, and ADU-none carry explicit not-applicable reasoning. Not link-stubs — each entry has city-specific arithmetic and effect-on-city statements.
