Eagle now has a typed active 2018 IWUIC overlay application, a linked official map with a text-only source receipt, explicit Fire Protection Plan and abutting-land distinctions, and a conservative 15-row edition-specific material subset.
The site now opens on Place, Build, Grow, Learn, and Saved. Set a ZIP, then pick the part of the house. Place pages are briefings; the claim graph stays on object records and JSON twins.
Twenty plant pages now carry exact Indiana 312 IAC 18-3-25 prohibitions, with enacted-name authority, effective dates, and two person-level subsection (d) exceptions kept distinct.
Maine now has 41 exact Chapter 273 legal records and 40 placement-bounded Forest Service fire-list records, while native range, hardiness, ecological context, and sale conditions remain separate answers.
The complete May 2026 Massachusetts Prohibited Plant List now supplies 40 exact plant-page legal records, retaining six staged sales phase-outs and separate orchard, bonsai, and permit operating conditions.
Fifty-three exact NC Extension Gardener Plant Toolbox profiles now contribute source-stated USDA half-zone ranges. They close 1,116 measured plant/state hardiness gaps across 48 states; the Curtis aster profile has no hardiness field and remains an explicit source gap.
The complete 75-row Part 575 plant list now supplies 31 exact New York legal records while keeping prohibited and regulated effects, nine current cultivar exemptions, notice duties, permit routes, and the expired Japanese barberry grace period distinct.
Twenty-three plant pages now carry exact Ohio OAC 901:5-30-01 restrictions, with the statutory cultivated food/feed boundary, the active reed-canary-grass feed exception, and clearly expired Callery pear and common privet transitions kept distinct.
Ohio's 352 Bulletin 921 plant records now surface as dated state-scoped evidence, while 51 records from two Black Hills sources remain visibly regional rather than statewide.
Five public full-text studies now contribute 122 measured species rows, including conditioned foliage, live and dead leaves, whole understory plants, and intact shoots. Ratings remain draft and script-derived; conflicting laboratory and curated evidence remains visible.
Prescott's current city code adopts the 2024 IWUIC and declares the entire city WUI; City GIS risk severity, project scope, effective date, and official confirmation remain open.
Alaska, South Carolina, Tennessee, Louisiana, Oklahoma, and Georgia plant surfaces now distinguish local fire-source evidence from occurrence, lineage, and site suitability.
Colorado, Texas, Utah, Kentucky, Wisconsin, Wyoming, and Nevada gain exact source scope while eight bounded local contexts stay visibly regional.
Virginia, Michigan, and Maryland gain 696 exact-state fire-evidence owners; Southern Idaho gains 419 explicitly regional owners; four existing explainers now join their state pages.
An autonomous primary-source pass adds 127 exact species/genus source-taxon rows from 15 Tier-1 studies and field programs, including South American, Chinese, French, U.S., European, and U.K. evidence. Forty-two new draft plant records bring the directory to 2,125 plants, while ambiguous taxa, uninterpreted middle ranks, duplicate datasets, and condition-only fuelbreak results remain excluded.
Twenty-seven plant pages now identify the Varner 2021 measurements as oven-dried litter bench tests, keeping the fuel condition and method distinct from landscaping advice.
Washoe County now has a typed active 2024 IWUIC Chapter 5 application, official parcel-map link, two-stage IR-class workflow, transition rule, and complete 15-row material crosswalk.
California gains a historically exact state source while Northern California, Marin, Puget Sound, Eastern Washington, the Willamette Valley, and Sun City Texas remain locally bounded.
Opened DFPC’s 2025 CWRC again. Sourced diffs now cover detached accessory walls, 500-square-foot and 25-percent remodel triggers, Immediate Zone plantings versus ASTM E136, stucco covering limits, ASTM E2886 as a code path, and the retrofit ladder. No extra state node. No Colorado chip option.
Opened DFPC’s 2025 CWRC again. Sourced diffs now cover IBHS versus adopted code, how to read a Class A listing, Class A service life, E119 versus a 1-hour exterior wall, intumescent vents, bird-block eaves, and written alternatives. No extra state node. No Colorado chip option.
The first standing overnight lanes land. 72 new field guides take the corpus from 111 to 183, with two new glossary terms. The materials queue closes honestly at twelve complete OSFM category censuses with JSON twins, seven new product records, and 38 requirement records from opened ORSC, IWUIC 2024, and Colorado CWRC sources. Nothing draft was promoted.
Insulation, walls and partitions, treated lumber and plywood join the public OSFM censuses, taking in-scope coverage to sixteen category codes. A listing no longer needs a product page to appear — where a product has none, the row says why. Every census row now names its product instead of showing an internal slug.
Dedicated derivation tests, four evidence-bounded plant ingests, a 1,015-row ICC-ES directory dataset, built-site integrity checks, and 70 explicit BML model rows harden the citation directory without promoting draft records.
An overnight source-ingest run takes the plant directory from 2,123 to 3,801 records and from 5,008 to 26,878 cited evidence rows. Eighty-seven registered sources moved to ingested, including the first large body of European, Mediterranean, and Australian fire-planting evidence. Statuses stay computed from the evidence; four sources failed honestly and are logged as failures.
Washington’s statewide IWUIC chapter is reserved until DNR hazard maps exist. Counties may adopt IWUIC locally now. The new hub states that. Construction ZIP resolution stays unknown.
A.R.S. 9-806 lets a city or town adopt a current wildland-urban interface code. That is parallel to 11-861 for counties. Arizona statewide stays none.
Arizona counties may adopt a WUI code. New Mexico’s statewide books are IBC and IRC. Neither state has a statewide IWUIC mandate. Construction ZIP resolution stays unknown.
Austin’s 2024 WUIC overlay is now a live city node. Shared object URLs highlight those diffs. Texas statewide stays none. ZIP 78701 resolves to the city.
Boise’s 2018 IFC amendments add Chapter 41 WUI construction, including Class A roofs for IR1. Idaho statewide stays none.
Clark County’s 2024 IWUIC overlay is now a live county node. Nevada statewide stays none because NAC 477.283 still deletes Chapter 5.
The 2025 Colorado Wildfire Resiliency Code is a sourced statewide book, so us-co exists for matching. It is not a Place-chip option and not a state hub. A Colorado ZIP highlights that node. Washington statewide IWUIC stays unknown until DNR maps exist.
Opened DFPC’s 2025 CWRC again. Sourced diffs now cover Class A covering versus assembly, roof-to-wall and deck flashing, wall-covering termination, ridge vents, exterior FRT weathering, Immediate Zone turf, and the R327-versus-CWUIC comparison. No extra state node.
The opened 2025 Colorado Wildfire Resiliency Code now has sourced diffs on skylights, valley metal, tile-profile gaps, eaves, Type X, pergolas, WUI mapping, and existing-house triggers. No extra state node. Washington maps stay draft. Utah waits until 2027.
Eagle’s 2018 IWUIC overlay is now a live city node. Idaho statewide stays none. The overlay is not a statewide construction book.
Flagstaff’s 2006 IWUIC overlay is now a live city node. Shared object URLs highlight those diffs. Arizona statewide stays none.
Idaho has no statewide IWUIC. Montana adopts a modified 2021 IWUIC that locals may elect to enforce. Construction ZIP resolution stays unknown.
Kittitas County Code 20.10 adopts IWUIC for all unincorporated land. Statewide WAC 51-55 stays reserved. The Place chip does not grow.
The site's URL tree was reorganized once, before first publish — materials unified under one branch, product records renamed to their own names, and merged landings added for all 53 states plus 23 sourced local jurisdictions.
Eighty-nine manufacturer-documented products and 13 quoted requirements expand useful coverage for windows, vents, garage doors, gutters, fences, roofs, roof closures, and exterior doors.
The materials explorer sorts listed and prescriptive matches first when Place is set. Unknown rows stay on the table. A California listing is not a Colorado listing.
Thirteen quoted requirement records, 14 manufacturer-documented prescriptive products, a queryable 295-product explorer, static requirement and status facets, reviewed diagrams, and an 826-row ICC-ES California supplement dataset.
ARM 24.301.181(21) replacement Table 503.1 is now cited on shared object URLs. Montana statewide stays coming-soon. Locals still elect.
Nevada’s State Fire Marshal adopts the 2018 IWUIC then deletes Chapter 5. The new hub states that. Construction ZIP resolution stays unknown.
A five-digit ZIP now fills USDA plant-hardiness zone from the 2023 PHZM ZIP listing. Oregon and California still resolve to a live place node. Other states stay unknown for WUI construction. Zone is not a building code.
ZIP codes in Oregon and California resolve to a live place node. The plant explorer hides noxious flags for that state. Oregon and California hubs are views over the graph. Can I use this here is listed, prescriptive, not accepted, or unknown.
First content slice maps placeId and appliesTo on live guides so the Place chip has geo rows to highlight.
The Place control now reorders guides, findings, requirements, standards, insurance, the homepage featured region, and the plant explorer. Other states stay on the page.
The plant corpus now has 2,031 draft records, 1,883 attributed photos, static state, zone, form, genus, source, and alternatives pages, query-addressable explorer filters, decoded placement schemes, and a human photo-review queue. A Marin source added 104 cited evidence rows; conflicts remain published and ratings remain script-derived.
This August 24 source reading was superseded after the current city code exposed Prescott's May 2026 adoption of the 2024 IWUIC. Arizona statewide still has no IWUIC mandate.
Each product object page and its JSON twin now report listed, prescriptive, not accepted, or unknown for live state nodes. The Place control still folds other states into details. A California listing is not a Colorado listing.
Can I use this here has a CC BY JSON twin at /materials/resolve.json. It reports listed, prescriptive, not accepted, or unknown for each live state node. A California listing is not a Colorado listing. This is not a permit.
Salt Lake City Code 18.44.010.B (Ord. 68-25) adopts the Utah Wildland Urban Interface Code on a mapped overlay. Utah statewide stays coming-soon. The Place chip does not grow.
Santa Fe County’s 2021 IWUIC overlay is now a live county node. Chapter 5 is deleted. New Mexico statewide stays none.
Sedona’s 2018 IWUIC overlay is now a live city node. Arizona statewide stays none.
Taylorsville Ordinance 25-15 adopts the Utah Wildland Urban Interface Code locally. Utah statewide stays coming-soon. The 2024 IWUIC is still not effective until 1 January 2027.
Unincorporated Teton County and the Town of Jackson now have separate 2024 IWUIC authority records with their own dates and scope. Wyoming statewide stays none.
Texas municipal codes are IRC and IBC. Florida’s update list is IBC through IECC. Neither state has a statewide IWUIC. Construction ZIP resolution stays unknown.

Washoe County adopts 2024 IWUIC Chapter 5 (Ord. 1736). Statewide NAC 477.283 still deletes Chapter 5. The Place chip does not grow.
Wyoming Council on Fire Prevention Chapter 1 is IBC through IFGC. IWUIC is not on that list. Construction ZIP resolution stays unknown.
Dovetail Partners' northeastern Minnesota firewise landscaping guide contributes 38 rated plants — the Florida flammability key applied to boreal-edge natives, with the document's own planting-distance doctrine preserved per plant. The corpus now holds 1,176 plants; 206 meet the two-independent-lineage bar, 79 are condemned by primary evidence, and 40 carry documented disagreements.
Product standards[] wired from listing notes. Generic /data routes and an OSFM 8165 vent census. Six new standard pages (E2726 skipped as withdrawn). Zone 0 material-class records, eight findings, R327 table with Sisters and Bend adopted (Bend via Ordinance NS-2552; BCD list still omits Bend), three R327 practice guides, five plant promotions, retrofit ladder, Zone 0 crosswalk, and /materials/compare/vents/.
Fire and Emergency New Zealand's Low Flammability Plants directory — the deepest lab-derived official plant flammability directory anywhere, grounded in Lincoln University shoot-flammability testing — contributes 413 taxa on a seven-level scale, plus twelve high-flammability environmental weeds. The corpus now holds 1,542 plants; 208 meet the two-independent-lineage bar, 128 are condemned by primary evidence, and 47 carry documented disagreements.
The directory quadruples to 654 records. FireApproved recovered the dead Eastern US Fire Performance Plant Selector (541 species rated by a seven-state USDA Forest Service program, offline for years) from the Internet Archive, verified it against the program's own 2014 master table, and ingested it with full citations. All ratings are now computed from the evidence by a published rule. Twenty-one plants meet the two-independent-lineage bar, six carry documented disagreements between sources, and the avoid list holds only plants condemned by two independent primary-evidence lineages.
The North Carolina Extension Gardener Plant Toolbox's 240 flammability-tagged plants join as the directory's first deliberately tier-less source. Rows for plants already rated by Bardon's 2005 list resolve to that root; everything else lands as corroboration that can never, by itself, move a rating — and the derivation run proves it, with zero rating changes. The corpus now holds 1,575 plants; 208 on-list, 128 avoid, 47 conflicts.
OSU Extension Bulletin 921 (2006), the only rated Midwest flammability list, is ingested from its sole surviving Wayback copy — 360 rated rows across eight tables resolving to 352 taxa, 67 of them new to the directory. The corpus now holds 1,045 plants; 197 meet the two-independent-lineage bar, 67 are condemned by primary evidence, and 16 carry genuine documented disagreements. A taxonomy repair pass also fixed fourteen records whose GBIF reconciliation had fallen back to genus- or family-level identities and merged eight duplicate records created under variant spellings.
OSFM handbook ingest now includes 8150 doors, 8170 ignition-resistant, and 8175 noncombustible. 235 products, 93 brands, 161 PNW 590 plants. Seven new test-method pages (SFM 12-7A-1 through 12-7A-4, ASTM E136, ASTM E84, ASTM E2707). Five new guides. Doors category and guides index are live.
First public content set, then a voice pass. Category and guide pages follow ISO 24495-1 / Federal Plain Language page shape. Not padded. Completeness means paths, mix-ups, and how to check.
A Place control (All, Oregon, California) highlights sourced local diffs on shared URLs. Other states stay on the page. JSON twins for guides and /places.json.
The directory's 2,030 plants are now explorable — search by name, filter by status, growth form, region, and your USDA zone, sort by evidence strength — and every plant page has become a full profile with a plain-English verdict banner, an at-a-glance fact grid, each source's own placement rule, evidence grouped by conclusion, and fire-safe alternatives.
The two-source rule now checks evidence lineage, not publisher names. Every plant citation became a structured evidence row resolving into a new source registry that records each source's tier (primary evidence vs. compilation) and derivation tree. Re-auditing the 55 on-list plants under the honest rule kept 15 and moved 40 back to the catalog, because their second source (the WA DNR Eastern Washington guide) describes itself as a compilation of other Firewise documents and cannot establish an independent line of evidence. Nothing was deleted; every demoted record keeps its citations and returns to the list when a verified-independent second lineage lands.
The Tasmania Fire Service's Fire Resisting Garden Plants brochure is the directory's first non-US ingest — 127 taxa in three flammability groups, transcribed explicitly from the rendered pages because the brochure's columns defeat text extraction. The corpus now holds 1,155 plants; 200 meet the two-independent-lineage bar, 79 are condemned by primary evidence, and 40 carry documented disagreements, including new transpacific ones like silver birch and Japanese maple rated High in Tasmania against Low ratings across US expert lists.
Twelve unique guides take the library from 88 to 100 live pages. Programs (Firewise site, CWPP, grants), Oregon agency split, California AB 38 and Oregon disclosure, smoke and PSPS, 13D versus wildfire, manufactured homes, existing-house retrofit, and rebuild-as-new-construction.
Virginia Firescapes 430-300 (2009), the Mid-Atlantic's original rated flammability list, is ingested from its Wayback-recovered PDF — 310 rows across six sideways-printed tables resolving to 307 taxa, 15 of them new. The corpus now holds 1,059 plants; 203 meet the two-independent-lineage bar, 74 are condemned by primary evidence, and 32 carry genuine documented disagreements — doubled by Virginia's blanket high rating for every evergreen against southern laboratory burns.
Arc 4's first wave lands four US rated lists — CSU Fact Sheet 6.305 with 0-10 ignitability scores split-mapped against Idaho, NC AG-874 as an edition-delta over Bardon 2005, Michigan's E2948, and the Wisconsin DNR firewise guide. The corpus now holds 1,669 plants; 244 meet the two-independent-lineage bar, 116 are condemned by primary evidence, and 70 carry documented disagreements.
Wave B builds out the avoid side of the directory. Yavapai County's Bulletin 34 contributes 200 entries including the corpus's first interior-Southwest fire-prone list, and Ashland, Oregon's Prohibited Flammable Plants ordinance becomes the directory's first regulatory evidence — an adopted municipal prohibition, not an opinion. The corpus now holds 1,772 plants; 257 on-list, 119 avoid, 79 documented conflicts.
Wave C adds APS Victoria's field-observation lists (144 plants from members' burnt properties and flare-up tests), FireSmart BC's plant chart as a Tier 2 corroborator with 91 rows resolving to PNW-590, and Tennessee's SP685 — confirmed a verbatim Virginia Firescapes copy, with 67 of its 78 rows chaining to that root. The corpus now holds 1,960 plants; 260 on-list, 117 avoid, 83 documented conflicts.
Wave D opens the non-English record. Valette 1990 — INRA Avignon's epiradiator inflammability notes, the laboratory root behind Provence fire-gardening — contributes monthly 0-5 ratings for 32 Mediterranean species, and the Generalitat Valenciana's low-flammability gardening guide adds 99 taxa with its warning list. The corpus now holds 2,029 plants; 264 on-list, 128 avoid, 91 documented conflicts.
Wave E adds the last two state voices with data in hand — Kentucky's ForFS 17-01 factsheet (three named flammables, ten defensible-space recommendations) and LSU's Hammond Research Station ornamental list as a tier-less corroborator. Derived ratings did not move, exactly as the evidence model intends for prose-level sources. The corpus closes the arc at 2,030 plants; 264 on-list, 128 avoid, 91 documented conflicts.
Three more primary-evidence sources ingested with full citations. The Idaho Firewise Master Database contributes 0-to-10 field scores for 377 taxa, Firewise Landscaping in North Carolina contributes 192 native ratings on its four-tier scale, and the NIST whole-plant shrub burns contribute 34 lab rankings. The directory now holds 986 plants; 105 meet the two-independent-lineage bar, 33 are condemned by independent primary evidence, and 6 carry genuine documented disagreements.
