Fire Season Maintenance Program

Fire season comes every year. Your property should be ready for all of them.
The Fire Season Maintenance Program is ongoing defensible space management built around Southern California’s fire season calendar — keeping your property compliant, documented, and genuinely ready year-round. Available to any property owner, with or without prior CWD work.
What it is
Defensible space is not a project. It is a condition.
Fine fuels — the grasses and small twigs that drive ignition and rate of spread — respond to weather in about one hour. When relative humidity drops below 25 percent and temperatures climb, they dry out fast. When Santa Ana conditions arrive in San Diego — offshore winds, humidity below 15 percent, gusts above 35 miles per hour, temperatures pushing into the 90s — the probability of ignition for exposed fine fuels in Zone 0 approaches 100 percent. Those conditions arrive on average 15 to 25 times per year in San Diego County.
A property that was genuinely defensible in April can have meaningful gaps by August if no one is managing it. Annual grasses cure in May and become fine fuel by June. Dead material accumulates through summer. Chaparral regrows. And when October arrives and the first Santa Ana event moves through, there is no time left to prepare.
The Fire Season Maintenance Program manages that cycle. CWD schedules visits around the fire season calendar — timed to when the work actually matters, not to a generic quarterly rotation. Every visit is documented. Every year ends with a complete record that demonstrates your property is actively managed — the documentation that makes the difference in an insurance conversation.
The Fire Season Maintenance Program is available to any property owner.
You do not need to have completed any prior CWD service. If your property has been cleared by another company, by your own crew, or by CWD — we can manage it from here and keep it ready.
Who it’s for
For anyone who wants fire season handled, not scrambled for.
- Property owners who have completed defensible space clearing — with CWD or anyone else — and want their investment maintained through the fire season calendar.
- Customers who want a documented maintenance record for insurance purposes — year-round compliance history rather than a single-point evaluation.
- Rural and semi-rural property owners where fire season preparation is complex enough that managing it personally is a real burden.
- Property owners who want the peace of mind of knowing their property is being monitored and maintained by people who understand fire risk — not just whoever can fit it in.
- Anyone who has gone through the spring scramble — realizing in April that the grasses are about to cure and nothing has been done — and decided not to do that again.
The fire season calendar
Built around when the work actually matters.
Southern California’s fire season has a specific rhythm driven by how fine fuels respond to weather, when chaparral dries out, and when Santa Ana events peak. The maintenance program is built around that rhythm — not a generic quarterly schedule.
April – May · Pre-Season (Critical)
The most time-sensitive work of the year. Annual grasses are curing — transitioning from green fine fuel to dry fine fuel that ignites instantly under red flag conditions. Once they cure, the window is closed until next year’s growth. Grass and weed control to the four-inch standard, dead material removal from Zones 0 and 1, lower limb pruning to break ladder fuel pathways, Zone 0 completely cleared of debris. This visit happens before fire season, not at the start of it.
June – September · Fire Season
Active monitoring through the most dangerous months. Fine fuel moisture is at its seasonal minimum. Monthly zone checks — new dead material removed, grass height maintained at four inches, Zone 0 kept completely clear, regrowth in Zone 1 addressed. Red flag warnings are common during this period. The property stays at its cleared standard when conditions are at their most volatile.
October – December · Santa Ana Season (High Alert)
The highest-risk period in San Diego County. Santa Ana conditions — offshore winds from the northeast, relative humidity below 15 percent, gusts above 35 mph — are responsible for San Diego’s most destructive fires. All deferred maintenance resolved before October. Post-event sweeps after each Santa Ana — roof, gutters, deck, and Zone 0 cleared of wind-deposited debris. Debris accumulation in Zone 0 after a Santa Ana event is an ember ignition pathway waiting to happen.
January – March · Post-Season
Property assessment after fire season closes. Irrigation inspection. Any damage from fire, wind, or rain addressed. Zone 1 planting modifications assessed — particularly any high-flammability species identified during the year that should be removed or replaced before the next fire season. Preparation begins for the next pre-season visit.
What you get
Managed. Documented. Ready.
Scheduled seasonal visits
Timed to the fire season calendar and your property’s specific maintenance requirements. CWD manages the schedule — you don’t need to track when the grasses are about to cure or when Santa Ana season begins.
Per-visit report
Delivered after every visit — brief, direct, useful. Work completed, any conditions flagged, photos of flagged areas. Delivered within 48 hours of each visit. You stay informed without having to ask.
Annual property summary
A complete record of all visits for the year — work completed each visit, property condition across the season, compliance status, and recommended scope adjustments for the coming year. This is the document that makes insurance renewal conversations straightforward. It demonstrates that your property is actively and professionally managed year-round, not just cleared once and left.
Priority scheduling
Program members go to the front of the queue for any additional work identified during a maintenance visit. If a visit surfaces conditions that need more than routine maintenance, CWD schedules the additional work before standard booking requests.
Insurance & documentation
A documented maintenance record is a different conversation with your carrier.
Insurance companies are increasingly asking not just whether a property has been cleared, but whether it is being actively managed. A single clearing job from two years ago doesn’t tell that story. An annual maintenance record — with visit dates, scope, photos, and a professional summary — does.
The Fire Season Maintenance Program produces that record systematically. Every visit documented. Every year ends with a summary. After two or three years of enrollment, you have a compliance history that demonstrates ongoing, professional management of your defensible space — the kind of record that supports insurance conversations in a way a one-time clearing never can.
CWD does not guarantee insurance outcomes and does not negotiate with carriers on your behalf.
What we provide is professional documentation of your property’s ongoing maintenance — the kind of record carriers look for when evaluating fire risk.
