Ridgeline Estate — Private Residence
Sonoma County, CA · 2021
A $7.2M estate sitting inside the primary ember-cast corridor of the Glass Fire.
RISK PROFILE
Firewise Score: 87 — Extreme Ignition Probability
Satellite fuel-load mapping identified the property as sitting within the primary ember-transport corridor, with prevailing Diablo wind vectors delivering spotting distances of up to 1.8 miles. Wood-shake roofing and unscreened attic venting created two direct ignition pathways. Adjacent chaparral had not been managed in 11 years. The insurer had issued a non-renewal notice 60 days prior.

INTERVENTION
Zone 1–3 Vegetation Management + Class-A Roof Retrofit
Firebreak implemented a 100-foot defensible-space program across all three zones, removing 4.2 acres of ladder fuels and creating separation between ornamental plantings and the structure. All wood-shake roofing was replaced with Class-A composite. Attic vents were fitted with 1/16-inch ember-resistant mesh. A shelter-in-place protocol and 15-minute evacuation sequence were documented and drilled with the property management team.

OUTCOME
Glass Fire, October 2021 — Structure Intact
The Glass Fire burned to within 340 feet of the property boundary. The structure sustained zero damage. The insurer reinstated the policy at standard terms, citing the Firebreak documentation as determinative. Total retrofit investment: $218,000. Insured replacement value preserved: $7.2M.

Pinecrest Ridge HOA
El Dorado County, CA · 2022
A master-planned community where shared fuel load made individual hardening insufficient.
RISK PROFILE
Contiguous Fuel Load Negated Individual Unit Compliance
Eleven of 60 units had completed individual Firewise assessments, but shared open space — 38 acres of unmaintained pine-oak understory — created a continuous ignition pathway that individual compliance could not address. Wind corridor modeling showed a slope-driven channel capable of 40-mph fire-weather gusts through the development's center spine. The county had flagged the HOA for CWPP non-compliance, blocking a pending FEMA hazard-mitigation grant.

CWPP Status

INTERVENTION
Community-Scale Fuel Management + CWPP Documentation Package
Firebreak designed a phased vegetation management program across all 38 acres of shared open space, prioritizing the wind-channel spine in Phase 1. An HOA-wide ember-resistant retrofit standard was established and embedded into CC&Rs. Firebreak authored the full CWPP documentation package — hazard assessment, mitigation strategy, and monitoring protocols — in the format required for El Dorado County approval. A community evacuation protocol covering all 60 units was designed, mapped, and presented at two HOA board sessions.

OUTCOME
Caldor Fire Corridor, August 2022 — All 60 Units Intact
The Caldor Fire burned through adjacent parcels, reaching the HOA's eastern boundary. All 60 structures were intact at post-fire survey. The completed CWPP documentation unlocked $1.4M in FEMA hazard-mitigation funding, which the HOA applied to Phase 2 and 3 fuel management. Three insurers who had issued non-renewal notices reinstated policies.
Verified
All 60 units intact. $1.4M FEMA funding unlocked.
CWPP documentation cleared county review. Three carriers reinstated.

Lassen Foothills Unified School District
Shasta County, CA · 2023
Critical public infrastructure across three campuses — 4,200 students, three WUI exposure profiles, one FEMA deadline.
RISK PROFILE
Three Campuses, Three Distinct WUI Exposure Profiles
The district's three campuses presented distinct risk profiles: the elementary school sat on a ridgeline with 270-degree exposure; the middle school occupied a valley floor with chimney-effect wind concentration; the high school bordered a 600-acre parcel of state-managed timber with deferred fuel treatment for eight years. The district had 90 days to submit a CWPP-compliant hazard mitigation plan or forfeit $12.7M in FEMA Pre-Disaster Mitigation funding.

3 distinct WUI profiles
FEMA Deadline

INTERVENTION
Campus-Specific Protocols + Unified CWPP Package
Firebreak deployed simultaneous assessment teams across all three campuses. Each campus received a site-specific hazard assessment, ember-resistant retrofit specification, and shelter-in-place / evacuation protocol calibrated to its occupancy profile and road-network constraints. The unified CWPP documentation was authored in the FEMA Hazard Mitigation Plan format, cross-referenced with California OES requirements. All three campus protocols were presented to district administration, school board, and county emergency management in a single joint session.

OUTCOME
Park Fire, 2023 — All Three Campuses Intact. $12.7M Grant Secured.
The Park Fire burned 429,000 acres across Shasta and Tehama counties — the fourth-largest in California history. All three district campuses were intact at post-fire survey. The CWPP documentation was approved by county and FEMA reviewers without revision requests. The $12.7M Pre-Disaster Mitigation grant was awarded in full, funding permanent fuel-management infrastructure across all three campuses.
