Wildfire mitigation

Wildfire mitigation mapping, from wildland firefighters

Our wildfire mitigation mapping is on Hawaiʻi Island: drone LiDAR over power lines where the utility rates the fire risk highest, and a map of the fire mitigation work tree crews record. Mapping a fire once it is burning is a different job, done by the same firefighters, and it has its own page.

Wildfire mitigation, in Hawaiʻi today

Our fire work in Hawaiʻi is mitigation: finding the trees and brush that have grown toward power lines, where they can start a fire, and keeping the record of the work that clears them. It is utility wildfire mitigation and vegetation management for Big Island Tree Service, the contractor that prunes and removes trees under Hawaiian Electric's lines island wide.

The work is led by our founder, Eli Polsky, who carries a wildland firefighter's red card with the FFT1, GISS and UASD qualifications behind it; his full record is on our About page.

Power line corridors in the highest fire risk tier

A drone LiDAR flight records a corridor in 3D: the ground, the poles and wires, and everything growing around them. We sort those returns into classes and flag the trees and brush by how close they have come to the lines, so vegetation managers can see which spans need a crew before the trucks roll. With repeat flights over the same stretches included, our count stands at 60+ miles flown.

Most of that corridor sits in Tier 3, the highest of Hawaiian Electric's three fire risk classes. In 2025 that was 13.25 of the 13.26 miles we flew; for 2026 it is 29.0 of the 47.5 planned miles. Near Kawaihae, the flags beside one pole in March 2025 were gone when the same stretch was flown again in April, after trimming.

Fire mitigation in the tree crews' records

On the ground, Big Island Tree Service crews log each tree they work on iPads, in Survey123 forms we programmed and review every day. Wildfire mitigation is one of the kinds of work a crew can record, and the program's reports count the miles worked in each of the utility's fire risk tiers.

From January 5 to August 31, 2026, the crews logged 4,814 trees as fire mitigation, and 24.7 of the 104.3 miles they worked were in Tier 3.

Tier 3 is the highest of the three fire risk classes on Hawaiian Electric's tier map. Corridor miles are measured along the lines in the areas flown. The crew figures are totals in the program's year to date workbook.

For landowners and agencies

Vegetation by height, near homes and roads

Landowners, counties and land agencies often start with a simpler question: what is growing near the homes, roads and lines that matter, and how tall is it? The drone LiDAR we fly over utility corridors answers that for a home site, a stretch of road or a whole property. It measures the height of the canopy and brush across the site, reaches the ground beneath them, and shows where tall growth stands close to a house, a driveway or a road edge.

On forested land in Volcano, one of our flights put 42 percent of the area flown under canopy taller than 6 ft.

Fuels mapping at the scale of a city plan

Our founder built this work on the mainland before Hawaii Mapping existed, and it is still running under our sister company, Rogue Reconnaissance. For the City of Ashland, Oregon it meant flying the whole town with drone LiDAR so a wildfire plan could say, block by block, where the fuel was.

About 4,300 acres went up in 100 acre pieces across 2024, at 250 feet. What came back was a classified point cloud and the products a planner can act on: ground and canopy models, a polygon for every tree crown, ladder fuel picked out of the vertical structure, and three exposure figures for each building in town. The 2025 Ashland Community Wildfire Protection Plan draws its fuels figures from it, names the company that flew it, and was accepted by the City Council on August 19, 2025.

A stand of conifer forest drawn from a drone point cloud, every return coloured by how far above the ground it sits: the ground itself tan, low brush blue and green, the tallest crowns red, each tree standing as a separate spire.
Height above the ground, measured for every point. Whether a surface fire can climb into the crowns is a question about this picture.

The same flight classed about 30,000 Douglas fir by health. Standing dead timber above a road is two problems at once: it can fall, and it burns readily.

The other half

Mapping the fire itself

Mitigation is the work that keeps a fire from starting. When one has started, the job changes: a night infrared flight, the heat found and mapped, a perimeter, and data the incident's GIS specialist can load.

That is a page of its own. It has what an incident team gets from a flight, the national wildland fire qualifications behind it, and the maps our founder has delivered to fires in Oregon with our sister company Rogue Reconnaissance.

Where to start

Utilities, tree crews and landowners

A utility or a tree crew: send the circuits or miles of line, whether they are transmission or distribution, your clearance spec and when you report. A landowner: the island, where the land is and about how many acres. We will come back with a plan for the flight and the data it would give you.
