Trade winds, lush valleys, and quiet country roads make Haiku feel far from wildfire danger. Still, recent island fires showed how fast wind, dry fuels, and embers can change everything. If you live in Haiku or Haiku‑Pauwela, you can lower your risk with simple yard work, smart home upgrades, and a plan for possible Public Safety Power Shutoffs.
This guide walks you through defensible space zones, plant priorities for Haiku, how PSPS works, and where to sign up for alerts. You will find quick weekend projects plus medium‑term upgrades that make a real difference. Let’s dive in.
Haiku wildfire risk at a glance
Haiku sits on windward Maui, where it is often more humid, yet invasive grasses and dry ridgelines can still drive fast‑moving fires during dry, windy spells. County leaders are expanding preparedness with new tools like Genasys Protect for evacuation notifications and zone mapping, which Maui County began rolling out in 2025. You can learn more about the county’s alert system in this report on the Genasys Protect rollout.
Wildfire seasons also affect insurance. The state continues to track major claims and market impacts, reinforcing the value of mitigation at the property level. See the Hawaii Insurance Division’s update on Maui wildfire claims data.
Create defensible space
Defensible space is the managed area around your home that reduces heat and ember exposure so firefighters can work safely. Maui recovery advisors and FEMA recommend a simple zone approach, paired with basic home hardening. Practical, island‑specific steps are detailed in the county’s Reducing Wildfire Risk to Your Home advisory.
Zone 0: 0–5 feet
- Keep it clean and noncombustible. Use hardscape near the house and remove mulch, leaf litter, and debris.
- Clear gutters, roof valleys, and under‑house areas.
- Move anything that burns away from exterior walls.
Zone 1: 5–30 feet
- Space and separate fuels. Keep plants low, well‑watered, and arranged in islands instead of continuous beds.
- Prune shrubs and trees so canopies do not touch each other or the house.
- Relocate woodpiles, vehicles, and propane tanks at least 30 feet from the structure when possible.
Zone 2: 30–100 feet
- Break ladder fuels. Trim lower tree branches to about 6 feet from the ground and reduce dense shrubs under trees.
- Keep grass low, ideally at or under 4 inches.
- If your lot cannot reach 100 feet, put extra emphasis on home hardening and work with neighbors to reduce fuels along shared lines.
Haiku plant priorities
- Focus first on non‑native grasses and shrubs that ignite easily, such as fountain grass and guinea grass, plus haole koa and dense stands of ironwood.
- Remove dead material, trim tree canopies 10 feet from roofs and other trees, and keep the first 6 feet of branches pruned.
- For replacements, choose lower‑growing, water‑wise species suited to island conditions. The county advisory above includes practical checklists.
Home hardening basics
- Roof: choose the highest fire‑resistant roofing you can and keep it clean.
- Vents and gaps: install ember‑resistant vent screens (mesh 1/8 inch or smaller) and seal openings at eaves, attics, and crawlspaces.
- Siding, decks, fences: favor ignition‑resistant materials and separate combustible fencing from the house. For more upgrade ideas, see HWMO’s homeowner tips and assessments as part of its Firewise program.
Evolving rules to watch
Hawaii’s 2025 law HB1064 establishes a state fire marshal framework and allows county fire chiefs to adopt and enforce minimum defensible space standards. Expect local standards, mapping, and inspections to evolve as the law is implemented. You can track the measure’s status at the HB1064 bill page.
PSPS in Haiku: what to know
A Public Safety Power Shutoff is when Hawaiian Electric proactively turns off power on specific circuits to reduce wildfire ignition risk in hazardous weather. PSPS is used case by case and can lead to multi‑hour or multi‑day outages while crews inspect lines before restoring power. Read the program overview from Hawaiian Electric’s PSPS safety page.
When PSPS might happen
Hawaiian Electric looks at several conditions together, including persistent drought, wind gusts around 45 mph or higher, and relative humidity below about 45 percent. Get a plain‑language summary in their explanation of PSPS criteria.
Are you in a PSPS area
PSPS zones are tied to specific utility circuits. To see if your address may be affected, use the Hawaiian Electric PSPS maps and address lookup. Sign up for utility notifications on the PSPS alert sign‑up page, and add the PSPS hotline to your contacts: 1‑844‑483‑8666. Also enroll in Maui County alerts as Genasys Protect becomes available.
PSPS prep checklist
- Keep a 7‑day kit with water, shelf‑stable food, flashlights, batteries, and a battery radio.
- Plan for medications and refrigeration; use coolers safely and avoid carbon‑monoxide risks.
- Register medical device needs with the utility and arrange backup power if required.
- Charge phones, battery packs, and laptops before high‑risk weather.
- Practice safe generator use outdoors, away from windows and never on shared circuits without proper transfer equipment.
Weekend‑ready projects for Haiku homes
- Clear Zone 0 within 5 feet of the house and clean gutters and roofs. See the county’s home risk‑reduction checklist.
- Mow grass to 4 inches or less, prune the first 6 feet of branches, and keep a 10‑foot clearance between tree canopies and the roofline.
- Replace highly combustible plants with lower, better‑hydrated choices suited to Hawaiʻi.
- Verify visible address numbers and clear driveway access for emergency vehicles.
- Coordinate with neighbors on shared fuel breaks and consider forming a Firewise group with help from HWMO’s Firewise program.
Insurance and documentation
The state reports significant wildfire claim activity, which keeps attention on mitigation and resilience. Keep before‑and‑after photos, contractor receipts, and materials lists for any defensible space or hardening projects. For market updates and contacts, see the Insurance Division’s Maui claims report.
