Start with the decision the estimate needs to support
A useful first estimate helps WTG understand where you want professional vegetation pretreatment considered. It does not prescribe a firebreak, prove product suitability or commit either party to a price. Begin with the buildings, operating areas or shared spaces that matter most, then identify nearby vegetation you want reviewed.
WTG provides planned ground application of Komodo to suitable vegetation and ground fuels. The treatment area is the proposed footprint of that service—not the floor area of the home, total parcel acreage, a defensible-space certification or every surface inside a generic perimeter. See what WTG can evaluate for treatment.
Divide the property into named treatment units
Treating the property as one number hides the decisions that make a proposal understandable. Divide the request into areas that an owner and crew can find again: “north vegetation edge,” “workshop west side,” “entry common area” or another plain site name. A unit may surround part of a priority structure, follow a landscape edge or cover a separate patch of suitable vegetation.
Keep noncontiguous areas separate even when you plan to add their square footage. This makes it easier to compare priorities, show optional phases, describe access and record what was actually completed.
- Give each unit a recognizable name or map label
- Identify the priority building or use related to the unit
- Describe the vegetation being considered
- Mark the beginning and end of a corridor or edge
- Keep optional or later phases separate from the base request
Use a sketch, aerial image or existing property map
A simple marked-up image is usually more useful than an unlabeled square-foot total. Outline each proposed unit, add a north arrow or recognizable feature, and show where photographs were taken when practical. Current aerial imagery can help with orientation, but tree canopy, shadows and older imagery can hide ground conditions.
County parcel viewers and owner-provided plans can be useful references; they are not automatically legal surveys or proof of authority. Identify uncertainty instead of adjusting a line to look precise. Do not walk steep, unstable or inaccessible terrain merely to complete an inquiry. See which property photographs help the review.
Measure simple shapes without turning them into prescriptions
Use basic geometry for a safe, approximate plan-view measurement. These formulas estimate map area only; they do not recommend how far treatment should extend from a structure or say that every plant inside the shape is suitable.
- Rectangle: length × width. A 100-foot by 50-foot unit is 5,000 square feet.
- Triangle: base × height ÷ 2. A 60-foot base with a 40-foot perpendicular height is 1,200 square feet.
- Circle: radius × radius × 3.14. A 20-foot radius is about 1,256 square feet.
- Irregular area: divide it into smaller rectangles or triangles, estimate each one and add them.
- Narrow corridor: average width × measured length, with wider sections listed separately.
Use horizontal map area as a starting number
Most sketches and mapping tools report a horizontal, plan-view footprint. A steep slope has more ground surface than the same outline on flat land, and vegetation adds vertical and irregular surfaces that square footage does not describe. Dense shrubs, tall grasses, trees and mixed understory can also require different field decisions within equal map areas.
For an initial inquiry, label the map area as approximate and note meaningful slopes. WTG can then review terrain, equipment reach, vegetation and the exact product plan instead of asking the owner to calculate a theoretical surface area.
Show exclusions instead of hiding them in the total
Mark buildings, paved surfaces, water features, wells, gardens, animal-use areas, neighboring property and other places that need separation or further review. Also show gaps where suitable vegetation is absent. A large polygon should not imply that every object or surface inside it receives application.
Subtract a clearly measured exclusion when that improves the estimate, but do not create false precision around every small gap. For complicated units, provide the gross outline, label material exclusions and let the proposal state how the included area was determined. Plan water-related exclusions before scope approval.
Keep defensible-space dimensions separate from application area
Colorado State Forest Service describes defensible space as managed zones around each building and recommends starting with the structure and working outward. Those official dimensions guide broader home-ignition-zone work; they do not automatically define a Komodo application polygon.
A treatment unit may include selected suitable vegetation within part of a wider mitigation plan, after mowing, pruning, removal or structure work is addressed. Do not multiply a standard radius around the house and assume the result is WTG’s scope. Compare pretreatment, defensible space and home hardening.
Do not convert mapped square feet directly into exact gallons
Komodo’s current FAQ gives a manufacturer-attributed ready-to-use coverage range of approximately 100–200 square feet per gallon and says equipment, vegetation type and ambient conditions affect coverage. That range can explain why area matters, but it is not a universal field rate, a quote or a promise that every formulation and property uses the same volume.
The exact product, instructions, suitable material and approved application plan govern product quantity. The September 15, 2025 Forest Service Qualified Products List includes Komodo only under its listed pretreatment and ground-application conditions; qualification does not validate an owner’s area estimate. Review Komodo qualification and formulation details.
Account for factors square footage cannot show
Two 5,000-square-foot units can be very different projects. The proposal should connect measured area with the actual conditions needed to perform and document the work. A map establishes location; it does not resolve suitability, productivity or price by itself.
- Vegetation type, height, density and continuity
- Slope, footing and equipment reach
- Gates, road access, staging and hose routing
- Irrigation, saturation and current weather conditions
- Water, animals, gardens and normal property use
- Mowing, pruning, removal or construction still planned
- Travel, mobilization and whether areas are completed in phases
Distinguish three different area numbers
An owner estimate, a proposed area and a completed area serve different purposes. The owner estimate begins the conversation. The proposed area appears in the written scope after suitability, boundaries and exclusions are reviewed. The completed area reflects field conditions, authorized changes and the units actually treated.
Keep those numbers labeled instead of silently replacing one with another. If the proposal uses estimated quantities, it should explain how a material difference will be reviewed and approved. The completion record should never describe an excluded or inaccessible unit as treated. Learn how to compare treatment proposals.
Plan large properties and community projects in phases
Ranches, estates, HOAs, commercial sites and public properties often contain several priority areas separated by roads, operations, ownership or unsuitable ground. Measure each unit and assign it to a base scope, option or later phase. This helps decision-makers compare equivalent work without treating the entire parcel or community as one application area.
For shared land, identify which units are common property and which require separate owner permission. For leased, easement or public areas, confirm who controls the land before the proposed polygon is treated as authorized. Review HOA and community planning or ranch and large-property planning.
Update the estimate when the property changes
Mowing, pruning, tree removal, grading, construction, new landscaping, irrigation changes, erosion or a changed property boundary can alter the proposed footprint. Report the change before application so the map, price, access plan and exclusions can be reviewed.
A crew should not expand into another unit or substitute a different area simply to preserve an earlier square-foot total. Material changes need the authorized decision and written record described in the proposal. Prepare the property and report changed conditions.
Send a useful estimate without delaying the inquiry
You do not need a survey-grade map or exact square footage to begin. Send the address, property type, priority areas, named units, approximate dimensions and current photographs when available. State which measurements came from a map, a plan or a safe field check, and label uncertain boundaries.
Request a wildfire pretreatment quote. WTG will review service availability, suitable vegetation, mapped boundaries, exclusions, access, travel and scheduling before confirming the proposed scope and price.
Questions about this service
Is treatment area the same as my house square footage?
No. House square footage describes interior floor area. Treatment area describes selected vegetation and ground-fuel units proposed for WTG review.
Should I estimate the entire parcel?
Usually not. Start with priority areas and suitable vegetation you want considered. Large acreage, buildings, roads and excluded uses should not be counted automatically.
How accurate does my first estimate need to be?
An approximate labeled map or set of dimensions is enough to begin. State how you measured it and where boundaries are uncertain; WTG reviews the proposed units before confirming scope.
How do I measure an irregular area?
Divide it into smaller simple shapes or trace an approximate polygon on a current map. Keep separate patches separate and show material exclusions instead of forcing one precise-looking number.
Can I use a defensible-space radius as the treatment area?
Not automatically. Defensible-space guidance addresses wider vegetation-management zones around structures. WTG’s product-specific application footprint must be reviewed separately.
Can I divide square feet by Komodo’s coverage range to get exact gallons?
No. Komodo’s manufacturer gives an approximate ready-to-use range and identifies equipment, vegetation and ambient conditions as variables. WTG uses the exact product documents and approved field plan to determine quantity.
What happens if the final area differs from my estimate?
The written proposal should explain the proposed area and how material changes are authorized. Completed-work records should reflect the units actually treated and any exclusions or field changes.
