What belongs in a wildfire mitigation project scope

Write the objective in observable terms

Wildfire mitigation is too broad to serve as a scope by itself. Start by describing the decisions the project should change on the ground. Examples include interrupting ladder fuels around retained ponderosa pine, removing combustible connections beside the home, improving a defined driveway corridor, or processing an existing slash accumulation.

Avoid promising that vegetation work will make a property fireproof. No contractor controls weather, embers, neighboring fuels, future maintenance, or fire behavior. A credible objective names the treated condition and its limits.

• Name the primary goal for each area: structure protection, access, understory reduction, forest health, cleanup, or maintenance.

• List the buildings, roads, forest stands, fields, or edges included in the project.

• Describe the fuel connection or maintenance problem the work should address.

• Record secondary goals such as screening, shade, habitat, trails, views, grazing, or future construction.

• State what the project does not claim to accomplish.

Map treatment units and boundaries

Divide the property by condition and treatment rather than relying on one acreage number. The first 5 feet around a house, an intermediate landscape zone, an open pine understory, a dense draw, a driveway, and a slash pile are different units even when they sit within the same parcel.

Use an aerial image, parcel sketch, flags, paint agreed for temporary marking, or GPS polygons. The written proposal should say which reference controls if the map and field marks conflict. Property corners should not be guessed. When work approaches a boundary, the owner should provide reliable location information or arrange the appropriate survey support.

Specify what stays and what is removed

Selective work is only selective when the decision rule is written. Terms such as small trees, brush, dead material, or overcrowded are open to interpretation. Where practical, add species, diameter ranges, height ranges, spacing objectives, or individual markings. If final selections will be made during work, identify who has authority and how delays will be handled.

The retain list is equally important. Mark priority overstory, screening, ornamental plants, habitat snags approved to remain, down logs, fences, irrigation, and other features. Hazardous or questionable trees should be assessed by a qualified person rather than casually included in a brush-clearing allowance.

• Define brush and tree size ranges included in the base price.

• State whether dead standing trees, down logs, stumps, and existing slash are included.

• Mark priority trees, screening, landscaping, snags, and habitat material to retain.

• Define pruning objectives and limits, including who makes tree-health decisions.

• Document how unmarked or borderline vegetation will be handled.

Choose a method for each unit

The scope should connect the method to site conditions. Forestry mulching may fit accessible understory, while hand work fits close-in structure zones, steep pockets, utilities, and detailed selective work. Chipping and haul-off are material-handling methods that usually follow cutting. Do not use the equipment list as a substitute for a treatment description.

Name any method the owner does not want, such as grubbing, broadcast herbicide, burning, machine travel in a protected area, or piling in a certain view corridor. If substitutions are allowed, require agreement before they are used.

Define every material outcome

Cut vegetation does not disappear. Logs, firewood, limbs, chips, masticated material, uprooted plants, soil, and trash may each need a different destination. Material handling often creates the largest difference between two estimates, so it should never be left to a general cleanup phrase.

If material stays, state where and in what condition. If it leaves, identify who loads it, whether trucking and disposal are included, and what happens if the volume differs from the estimate. If piles are created, define locations and whether later chipping, burning, or removal is part of the contract. Check current outdoor-burning rules and restrictions separately. A pile is not a disposal plan by itself.

Inventory access and protected constraints

Walk the route from the public road to every treatment unit. Record gate openings, surface type, curves, grades, overhead limbs and lines, culverts, bridges, soft shoulders, and turnaround or trailer-staging space. The contractor should confirm that the proposed carrier, chipper, truck, and trailer can reach the work without relying on an assumption.

Mark septic tanks and drain fields, wells, underground utilities, propane systems, irrigation, fences, retaining walls, private roads, and neighboring property. The owner should use the appropriate utility-locate process and disclose known private facilities that public locating may not mark. Establish no-travel buffers where needed.

• Gate width, road width, overhead clearance, turning radius, grade, and surface condition recorded.

• Culvert, bridge, driveway, or private-road load concerns disclosed.

• Equipment, truck, trailer, chip, log, and debris staging locations agreed.

• Overhead and underground utilities located through the appropriate process.

• Private water, septic, propane, irrigation, and electrical features marked.

• Property lines and no-entry areas reliably identified.

• Rock, steep slopes, soft ground, drainage, and erosion concerns documented.

Check agency and site requirements before work

Some vegetation work on forestland may fall under Washington's Forest Practices rules, especially when it involves timber harvest, forest roads, water crossings, or other regulated forest practices. Requirements depend on the activity and site. Washington DNR provides the application process and illustrated guidance, but the owner should confirm the actual classification instead of relying on a contractor's generic statement.

Spokane County regulates critical areas that can include wetlands, fish and wildlife habitat conservation areas, geologically hazardous areas, aquifer-recharge areas, and frequently flooded areas. Other city, county, state, federal, road, shoreline, or fire-code requirements may also apply. Verify jurisdiction and current rules before work begins.

Burn bans, rule burns, equipment restrictions, and air-quality requirements can change with conditions. If burning is proposed, treat authorization, timing, tending, extinguishment, and alternatives as separate decisions. Never assume that land-clearing debris may be burned because it can be piled.

Describe the finished condition

Words such as clean, cleared, park-like, and mulched mean different things to different people. Replace them with observable standards and honest tolerances. Natural terrain and dense vegetation make perfect uniformity unrealistic, but that does not prevent the parties from defining what a reasonable final walk should show.

• Maximum or target stump height by treatment unit, with terrain exceptions stated.

• Expected chip or mulch particle range and residue depth described without guaranteeing uniformity.

• Location and maximum dimensions of piles or log decks identified.

• Raking, blowing, road cleanup, fence cleanup, and structure-adjacent detail work listed.

• Acceptable rutting, soil exposure, scarification, and incidental branch damage addressed.

• Repair responsibility for documented versus undisclosed site features stated.

• Final walk, punch-list process, and completion standard included.

Normalize estimates before comparing price

Put proposals side by side and identify what each contractor included, excluded, or assumed. A total price is meaningful only after treatment area, production assumptions, material handling, mobilization, and finish are aligned. Ask for alternates when a decision materially affects cost, such as leaving chips versus hauling debris.

Use this pre-work scope checklist

A final scope should be understandable to someone who did not attend the site walk. Attach the map, photographs, material schedule, and accepted proposal to the same agreement. Revisit the markings with the crew lead before equipment starts.

• Project objectives and limits written in observable terms.

• Treatment units mapped, labeled, and marked on the ground where needed.

• Included and excluded vegetation defined by unit.

• Retained trees, landscaping, habitat features, and screening marked.

• Treatment method assigned to each unit with substitution rules.

• Brush, chips, mulch, slash, logs, firewood, stumps, and trash given written outcomes.

• Access route, staging, gate, road, bridge, culvert, and turnaround confirmed for proposed equipment.

• Utilities, wells, septic, propane, irrigation, fences, and boundaries located or marked.

• Critical areas, forest-practices, burning, road-use, and other agency questions resolved.

• Finish standards, tolerances, cleanup, final walk, and punch-list process written.

• Price, alternates, mobilization, disposal, change authorization, and payment schedule clear.

• Owner maintenance and likely retreatment discussed before completion.
