Stump Grinding Quotes: Utilities, Depth, Chips, Restoration

A customer points to a cut trunk beside the driveway and asks for a price to remove the stump and leave everything clean.

The contractor writes one line:

Grind stump below grade, remove debris, and restore area.

That sentence leaves almost every cost driver open. Is the quoted diameter the narrow cut face or the wide root flare? Does below grade mean 4 inches below the top of a raised root, 8 inches below the surrounding lawn, or deep enough for a new tree? Are the roots running under the walk included? Does the free 811 request cover the irrigation main, landscape-lighting cable, propane line, septic components, invisible fence, or power beyond the meter? Are the mixed chips and soil left in a mound, hauled away, or replaced with screened topsoil? Does restore mean rake the crater, seed it, install sod, or repair cracked pavement?

A good stump grinding quote answers those questions before a cutter wheel enters the ground. It identifies each stump, uses a repeatable measuring method, states the grinding envelope and depth reference, separates ordinary grinding from root chasing and excavation, assigns the locate workflow, defines what happens near marked or suspected facilities, records access and hidden-condition assumptions, and prices debris and restoration as measurable work.

This guide addresses U.S. quoting and field documentation. One-call laws, ticket timing, mark validity, tolerance zones, excavation methods, tree permits, contractor licensing, consumer-contract rules, and right-of-way controls vary by state and locality. The quote should point to the governing rules for the jobsite instead of treating a national guide or another state’s process as local law.

Use Documentorium to describe the actual stump and finish, not a generic removal promise. Put each stump ID, location, customer objective, cut-face and root-flare measurements, visible roots, access path, utilities reported by the customer, public-space issues, and restoration area in the site assessment checklist. Use the tree-service quote for the grinding envelope, depth reference, surface-root allowance, utility prerequisites, machine access, chips or haul-off, backfill, grading, seed or sod, price, and exclusions. Move the accepted responsibilities and change process into the tree-service contract, then issue the tree-service work order with the final ticket and site information. The utility-locate photo-log guide shows how to preserve the ticket, marks, private-facility limits, and stop decision.

Start with the customer’s end use

Grinding is not one standardized endpoint. Ask what must occupy the space after the stump is gone.

Common objectives include:

• removing a mowing obstacle;
• eliminating a trip or maintenance hazard;
• preparing a shallow lawn patch;
• opening a planting bed;
• reducing visible stump material at a fence or property edge;
• preparing for a replacement tree;
• clearing a route for irrigation, drainage, fencing, paving, a footing, or another improvement;
• controlling sprouts from a species that can regenerate;
• removing the entire root mass rather than grinding only accessible wood.

Those are not equivalent scopes. A standard grind suitable for turf may leave substantial roots below and beyond the grinding pocket. It does not prove the soil is suitable for a foundation, pavement, pipe, post, or replacement tree. If the next project needs engineered subgrade, full root removal, utility exposure, compaction testing, or excavation below the ordinary grinding envelope, quote that work separately or refer it to the appropriate contractor.

Write the objective in the estimate:

Objective is to eliminate the visible mowing obstruction and prepare a 6-foot-diameter lawn patch. Scope is not preparation for a structure, pavement, utility trench, fence post, or replacement tree.

That sentence gives the grinding depth and restoration specification a reason.

Identify every stump unambiguously

Do not rely on front stump when a property contains several cut trees or clustered stems. Give each stump an identifier and tie it to a marked plan or photographs.

Record at least:

Mark the approved stump with removable ribbon, a numbered stake placed safely beside it, or an annotated image. Do not spray paint living trees or attach hardware where local rules or sound arboricultural practice prohibit it.

For a boundary stump, obtain the necessary owner authorization before mobilization. A customer’s payment does not establish ownership of wood or roots on adjoining land. If the stump is in a public right-of-way, easement, common area, rental property, or regulated tree site, identify who can authorize the work and what permit or consent is needed.

Define diameter instead of advertising a price per inch

$5 per inch sounds objective until two estimators measure different parts of the same stump.

A recently cut trunk may be 24 inches across at the saw cut, 37 inches across at the root flare, and nearly 60 inches across when two broad buttress roots are included. A low multi-stem stump may not have one circular diameter at all.

Choose and disclose a method. For example:

Billable stump diameter is the widest straight-line dimension of solid stump wood measured at the specified measurement plane, excluding separately identified surface roots. The measurement plane is 6 inches above the surrounding finished ground or the highest practical plane below that level when the stump is cut lower. Irregular and multi-stem stumps are measured by the minimum rectangle enclosing connected stump wood at that plane, using the longer dimension for the quoted band.

That is only one possible commercial method. A contractor may use:

• widest diameter at the cut face;
• average of two perpendicular dimensions;
• maximum flare width at ground level;
• diameter bands rather than a per-inch rate;
• machine time for highly irregular clusters;
• a fixed price for the photographed stump.

The important point is consistency. Put the method, measured dimensions, and resulting price in the quote.

Example schedule:

Do not quietly switch from cut-face diameter to flare diameter after acceptance. If inspection was limited by soil, mulch, ivy, snow, stored material, or a deck, state what must be exposed before final measurement and whether the proposal is budgetary or firm.

Use a three-dimensional grinding envelope

Depth alone does not define the work. The quote needs a horizontal envelope, a vertical limit, and a reference surface.

Horizontal limit

State how far the cutter will work beyond the identified stump wood:

Grind accessible stump wood and root flare within the painted 6-foot-diameter work circle shown in Photo 3. Roots continuing outside that circle are excluded unless listed as R-series line items.

This avoids an unlimited promise to follow roots through the yard.

Vertical limit

State the target depth and how it will be checked:

Target grinding depth is 8 inches below the surrounding undisturbed lawn grade at the perimeter of the work circle, measured after loose grindings are removed from the measurement point.

Do not measure from the top of a remaining stump, a chip mound, a raised buttress root, or a temporary rut. If the surrounding grade varies, establish reference points or elevations before work.

Practical tolerance

Wood, stones, utilities, adjacent structures, machine geometry, and soil conditions make a perfectly uniform underground plane unrealistic. State an appropriate tolerance and the consequence of an obstruction:

Contractor will make reasonable passes to achieve the specified depth throughout accessible stump wood. The depth is not guaranteed inside a utility tolerance zone, beneath paving or structures, outside the machine’s safe reach, or where unanticipated concrete, metal, rock, protected roots, or other obstructions require a stop and written change.

Verification points

For a higher-value or disputed site, agree on where depth will be documented. A marked rod at three or four exposed points is better evidence than a photo of an empty-looking crater. Record the perimeter reference, point locations, and reading before backfill.

Explain what stump grinding does not remove

A cutter reduces accessible wood to fragments. It does not normally extract the whole stump-and-root system.

Unless specifically included, ordinary grinding does not promise:

• removal of every root;
• removal of roots under buildings, walks, roads, walls, fences, utilities, or protected areas;
• excavation of the root ball as one mass;
• removal of all wood below the grinding depth;
• prevention of every future sprout;
• immediate decomposition of remaining roots;
• structural fill or engineered subgrade;
• elimination of future settlement as buried roots decay;
• eradication of disease organisms from soil;
• a planting hole suitable for a new tree;
• repair of damage the roots caused before the job.

Use plain language:

Grinding leaves roots outside and below the specified envelope. Those roots may remain firm, decay, settle, or produce shoots depending on species and condition. Sprout treatment, repeat cutting, herbicide work, root excavation, soil remediation, and structural preparation are not included unless separately listed.

If chemical treatment is offered, identify the product, target, applicator qualification, label compliance, customer approvals, drift controls, and whether the treatment is an optional line item. Do not imply that a pesticide application is automatically part of mechanical grinding.

Treat surface roots as separate measured work

Includes roots is as open-ended as includes cleanup.

Map each visible root or define a capped allowance:

• root ID;
• starting and ending points;
• marked length;
• maximum visible width;
• target depth below surrounding grade;
• nearby hardscape, trees, utilities, and property lines;
• restoration surface;
• price basis;
• stop condition.

Example:

R-01: Grind the photographed surface root from the S-01 flare to the blue stake, maximum marked length 9 feet and maximum visible width 7 inches, to 4 inches below adjacent lawn grade. Stop before the sidewalk edge and outside every legally required utility tolerance zone. Roots beyond the stake, beneath the sidewalk, or discovered below grade are excluded.

Mechanical root chasing can move the cutter far beyond the original stump pocket. That changes the locate area, restoration quantity, access path, and risk. The 811 request and any required private locate should cover the entire proposed root corridor—not just a circle around the stump.

Where a proposed root belongs to a living tree, stop treating the task as ordinary stump work. Cutting a structural root can harm stability and health. Local rules may require an arborist review or permit. Portland, for example, currently requires a permit to prune qualifying roots of street trees and says its inspector determines which exposed roots may be cut. That is a local example, not a national threshold.

Make utility locating a prerequisite, not a disclaimer

A clause saying customer responsible for utilities does not make a rotating cutter safe.

PHMSA tells homeowners and professional excavators to contact 811 before digging and to wait the required time, respect marks, and dig with care. The Common Ground Alliance’s current Best Practices 22.0 organize a broader damage-prevention workflow. State law supplies the actual notice period, ticket life, tolerance zone, positive-response rules, exemptions, and required excavation methods for the site.

Portland’s current tree removal and replanting permit instructions make the connection explicit: permit holders must call the Oregon Utility Locate Hotline before ground-disturbing activities such as stump grinding or tree planting. Other jurisdictions may use different wording, but a power-driven stump cutter should never be waved off as only landscaping without checking the governing one-call law.

Identify the excavator of record

The quote should state who submits and controls the ticket. In many systems, the party performing the excavation should have its own valid ticket rather than rely on a request created for a different contractor or earlier scope.

Record:

• excavator legal name and contact;
• one-call center and ticket number;
• exact address and work description;
• stump and root IDs covered;
• mapped or white-lined work area;
• proposed start window;
• ticket status and expiration or renewal point;
• every notified facility operator;
• every positive response;
• date and condition of field marks at the start of work;
• re-mark or conflict requests;
• private-locate record.

Do not promise a universal number of advance days in a national quote template. The CGA state resource map shows why: notice periods, mark-validity periods, and tolerance-zone widths differ among states. Use the current state one-call rules for the job.

Delineate the full work area

Pre-mark or white-line the proposed excavation when required and whenever it improves clarity. Include:

• the stump grinding circle;
• every surface-root corridor;
• anticipated chip-removal or soil-removal excavation;
• proposed backfill, irrigation, edging, or planting work that disturbs soil;
• machine positioning where ground contact could disturb shallow facilities;
• any alternate access or expanded area that may become necessary.

One vague ticket for front yard is not a substitute for a clear field scope. Conversely, do not request an unnecessarily huge area simply to avoid planning the work.

Wait for complete positive response

Paint and flags are only part of the response process. Before work, compare the ticket’s notified-member list with the recorded responses. A facility operator may mark, report no conflict, provide instructions, arrange a meeting, or indicate another status permitted by the state system.

The start condition can say:

Grinding will not begin until the statutory waiting period has passed, all required facility-owner responses are complete and reviewed, the ticket is active for the actual work area, marks are visible, and unresolved no-response, conflict, or access issues have been cleared under the governing process.

Silence from one member is not an invitation to assume no line exists.

Respect the state-specific tolerance zone

A locate mark represents an approximate horizontal location under the governing law; it is not a guarantee of depth. The tolerance zone and the permitted means of exposing or working near a facility vary by state and sometimes by facility.

For example, Southern California’s DigAlert guidance currently describes a 24-inch tolerance zone on each side of the outside diameter and requires hand exposure before power equipment is used in conflict. That is a California example. It must not be copied into a quote for a state with an 18-inch zone, a different measurement method, or different safe-excavation requirements.

A portable national clause is:

Contractor will observe the tolerance zone and safe-excavation practices required by the law, one-call rules, facility-owner instructions, and site safety plan applicable to this location. Stump grinding with powered cutting equipment is excluded within that zone unless the facility has been lawfully exposed or otherwise protected and the responsible parties have documented a safe, permitted work method. A mark alone does not authorize powered grinding over the facility.

When the required safe method is incompatible with a stump grinder, omit that part of the stump, revise the scope, coordinate with the facility owner, or use another approved removal method. The quote should not force the operator to choose between contract completion and utility safety.

Preserve marks and stop when conditions disagree

Photograph marks before staging equipment. Protect flags and paint where practical. Request re-marking when marks are lost, disturbed, illegible, or expired. Do not repaint a utility line based on memory.

Stop work when:

• an unmarked line, conduit, tracer wire, pipe, warning tape, vault, or utility appurtenance appears;
• field marks conflict with maps, ticket responses, surface features, or exposed facilities;
• the scope extends outside the requested area;
• required marks are missing or damaged;
• the ticket is not active;
• a facility cannot be safely exposed or protected;
• the customer asks the crew to just avoid a suspected line;
• a facility is contacted, scraped, nicked, pulled, or otherwise damaged.

The emergency and damage notification steps should follow state law and facility-owner instructions. Even apparently minor sheath, coating, tracer-wire, or conduit damage can matter; do not conceal it under backfill.

Separate public/member locates from private facilities

An 811 ticket does not promise that every buried object on the property will be marked.

CGA Best Practices 22.0 explains that an 811 center notifies its participating members; private service lines or facilities owned by nonmembers may exist and will not be located through that notification. DigAlert similarly tells excavators that members mark lines they own or maintain, often only to a meter, and gives private fuel runs as examples of lines they do not mark.

Ownership boundaries vary. Do not assume that utility side of meter is universal for every service or site.

Create a private-facility inventory with the customer:

The customer should disclose known facilities and records, but the contractor still needs a safe work decision. A useful clause is:

The public one-call ticket covers only facilities whose participating owners respond to that ticket. Customer will identify all known privately owned or nonmember facilities and provide available plans and contacts. Contractor will arrange the listed private locating service [included / allowance / customer-direct]. Records and locates are planning evidence, not a guarantee of depth or the absence of other facilities. Work stops on any unknown or conflicting condition.

Avoid an absolute customer warranty that no private utilities exist. Many property owners genuinely do not know. Price a discovery and escalation process instead.

Use a utility responsibility matrix

Assign each step instead of using utilities by others.

Adapt the matrix to local law. A contract cannot transfer a statutory duty away from the party on whom the law places it.

Survey access as carefully as the stump

The cheapest machine on paper is irrelevant if it cannot reach the work safely.

Measure and photograph:

• narrowest gate, passage, and turn;
• steps, curbs, walls, and thresholds;
• slope and cross-slope;
• overhead branches, wires, eaves, awnings, and balconies;
• weak paving, pavers, septic covers, vaults, basements, decks, and retaining structures;
• turf, wet soil, irrigation heads, and finished landscaping;
• loading and trailer parking;
• public sidewalk, bike lane, street, parking, and pedestrian exposure;
• work-zone radius and chip trajectory controls;
• distance for manual removal of grindings and delivery of fill;
• noise or work-hour restrictions;
• locked access, animals, tenants, and customer vehicles.

State the required opening and route:

Price assumes unobstructed access through the 42-inch gate and along the photographed side-yard route for a machine no wider than 36 inches. Customer will remove furniture and unlock the gate. Contractor will use ground-protection mats at the lawn turn. Fence disassembly, crane placement, machine lifting, structural assessment, and repair of pre-existing weak or concealed surfaces are excluded.

Do not promise no marks on lawn while moving heavy equipment across saturated soil. Define ordinary protection, postponement conditions, and the restoration included for contractor-caused ruts. Separate unavoidable turf compression within the approved access path from negligent damage; local law may limit how broadly that allocation can be written.

Record embedded and hidden-condition assumptions

Stumps can contain or conceal:

• nails, screws, spikes, hooks, wire, chain, fence fabric, clothesline hardware, and signs;
• concrete, masonry, landscape edging, gravel, riprap, and construction fill;
• rocks and boulders;
• old irrigation, lighting, pipe, conduit, cable, or drainage;
• soil packed into crotches and cavities;
• root grafts or connected stumps;
• animal nests, insects, poison ivy, and contaminated debris;
• burned, hollow, rotten, or unusually hard wood;
• previous grinding spoils placed over remaining wood.

Inspect with the customer, remove visible attachments, and ask about the site’s history. A metal detector may reduce risk but cannot prove the stump is free of metal or utilities. State the process for a hidden obstruction:

Price assumes ordinary wood and soil. On discovering embedded metal, concrete, significant rock, unknown facilities, contamination, or another unsafe obstruction, Contractor will stop the affected work, make the area safe, document the condition, and offer a written change, omit the obstructed portion with an equitable credit where appropriate, or terminate that line item under the agreement. No extra work proceeds without the stated emergency or change-order authority.

That is more useful than either all hidden conditions included or a blank check.

Define the machine safety boundary

ANSI Z133-2026 is the current U.S. arboricultural safety standard. It replaced the prior edition and addresses arboricultural operations, including equipment and work practices. Where applicable, OSHA’s machine-guarding requirements call for guarding against hazards such as rotating parts and flying chips and sparks. OSHA’s tree-care small-business issues document discusses stump-grinder controls, but an issues document is not itself a final enforceable tree-care standard; use it as background, not as the citation for a legal claim.

The job plan and quote assumptions should support:

• a trained and authorized operator;
• pre-use inspection and manufacturer-required guards;
• the correct machine for stump, slope, access, and ground conditions;
• required personal protective equipment;
• removal of people, pets, vehicles, and fragile property from the work zone;
• screens or other controls selected for the actual chip path;
• traffic and pedestrian control where the work affects public movement;
• no bypassing guards or interlocks;
• equipment shutdown, energy control, and manufacturer procedures before clearing jams, servicing, or entering a danger area;
• safe fuel, transport, and parking practices;
• communication between operator and spotter;
• a stop for underground, overhead, stability, visibility, or public-incursion hazards.

Do not print one universal exclusion-zone distance in every proposal. Use the machine manufacturer’s instructions and the site-specific work plan. Record customer obligations such as keeping occupants and pets inside and vehicles out of the agreed area, but keep control of the active work zone with the contractor.

Separate grinding, cleanup, hauling, and disposal

Grinding creates a mixed material of wood fragments, bark, roots, and soil. Its loose volume can be surprising and cannot be predicted perfectly from trunk diameter alone.

Use separate line items:

1. Grinding: reduce wood inside the defined envelope.
2. Pocket cleanup: remove loose grindings enough to verify depth.
3. Material disposition: leave, spread, load, haul, or dispose of a measured quantity.
4. Backfill: import and place a specified material and quantity.
5. Surface restoration: rough grade, finish grade, seed, sod, mulch, paving, or other finish.

If grindings stay

State where and how:

Rake generated grindings into one mound centered in the former stump area, not exceeding approximately 12 inches above adjacent grade. No hauling, topsoil, seed, or settlement return is included.

Or:

Spread up to 2 cubic yards of suitable grindings in the customer-designated bed to a maximum loose depth of 3 inches, keeping material away from trunks, foundations, drains, utilities, and paved surfaces. Excess is priced under the haul unit rate.

Do not promise that mixed stump grindings are clean decorative mulch. They may contain soil, stones, roots, decay, and incidental debris.

If material is hauled

Define the unit and limit:

Base price includes loading and lawful disposal of up to 3 cubic yards of generated loose grindings, measured by the truck container’s known volume. Additional generated material requires customer approval at the stated per-cubic-yard rate. Pre-existing soil, mulch, trash, concrete, rock, and landscaping debris are excluded.

An all chips removed fixed price can work when the contractor accepts the volume risk after a complete site visit. Otherwise use an allowance with a transparent unit rate. State whether the contractor owns removed material and whether disposal fees, travel, and minimum loads are included.

Do not confuse chips with excavation spoil

Deep grinding, root chasing, and regrading can generate more mineral soil than a normal stump pocket. Quote soil hauling separately when disposal classification, weight, contamination, or dumping fees differ. Never represent potentially contaminated soil as ordinary clean fill without appropriate evaluation.

Specify restoration as a layered assembly

Restore lawn should become a material-and-work specification.

No restoration

Grinding and selected chip removal only. Pocket remains open or filled only by residual grindings as described. Customer accepts all topsoil, grading, seed/sod, watering, erosion control, and future settlement work.

Rough backfill

Remove loose grindings to the included limit; place up to 1.5 cubic yards of [specified fill/topsoil] in lifts practicable for the small area; leave approximately 1 inch above adjacent grade to allow for settlement; rough rake. No seed, sod, fine grading, irrigation repair, compaction testing, or return visit.

Seeded lawn patch

Define:

• patch dimensions or maximum square footage;
• grindings and root-wood removal depth;
• imported soil type and estimated volume;
• final grade and drainage intent;
• seed species or blend and application basis;
• starter fertilizer only if appropriate and agreed;
• mulch or erosion blanket;
• watering responsibility;
• protection from traffic and pets;
• germination, weed, washout, drought, and seasonal limits;
• whether a return visit is included.

Example:

Prepare up to 40 square feet for seed by removing loose grindings to 6 inches below final lawn grade, placing screened topsoil to match surrounding drainage without burying adjacent trunks or structures, raking, applying the named seed blend and straw, and issuing written watering instructions. Customer supplies water and performs ongoing watering and mowing. Establishment is not guaranteed against inadequate watering, heat, freeze, erosion, animals, herbicide, disease, unsuitable surrounding soil, or settlement of roots outside the restored layer.

Sod

State sod variety, patch size, soil preparation, seams, initial watering, ongoing care, and replacement terms. Clarify whether irrigation heads are adjusted or simply protected. A green patch on installation day is not an unconditional promise of long-term establishment.

Structural or paved restoration

Do not use wood chips or organic grindings as structural fill under pavement or foundations. A paving or construction scope may require excavation of remaining organic material, suitable aggregate, controlled lifts, compaction, drainage, testing, permits, and a qualified contractor. Separate that scope from ordinary stump grinding.

Address settlement honestly

Settlement can come from loose backfill, decay of roots left below or beyond the work, buried voids, water movement, and traffic. A shallow lawn restoration cannot control all of those mechanisms.

Define any return commitment:

One settlement adjustment is included for the restored patch if requested within the written warranty period and if the depression results from included backfill placement. The remedy is limited to adding and grading up to [quantity] of specified soil [and reseeding, if included]. Settlement caused by roots outside the grinding envelope, drainage, erosion, burrowing animals, utility work, vehicle traffic, customer excavation, or failure to follow care instructions is excluded to the extent permitted by law.

Or state that no return is included and price future top-up work. Avoid no settlement guaranteed; it promises control over material that remains underground.

Allocate permits, ownership, and public-space duties

Before pricing, classify the location:

• private property under the customer’s control;
• rental property;
• condominium or association common area;
• property-line or shared tree location;
• utility easement;
• public right-of-way or planting strip;
• protected, heritage, landmark, or replacement-required tree site;
• active construction project with separate permit controls.

Local rules may govern removal completion, stump grinding, root cutting, replanting, work hours, traffic control, contractor qualifications, and restoration. Portland currently requires permits for activities that may harm a street tree and its removal instructions couple the permit with 811 before stump grinding. Another city may assign stump work to a public agency, require a licensed tree contractor, prohibit grinding until inspection, or require replacement planting.

Use a permit schedule:

Never say permit by owner without saying whether the contractor will verify issuance and conditions before starting. A customer cannot authorize the contractor to violate a permit condition.

Price the actual production drivers

A defendable price considers more than diameter.

Common components are:

• mobilization and minimum charge;
• stump count and measured size;
• wood species and condition;
• cut height and required preliminary saw work;
• standard depth and additional depth increments;
• flare width and individually listed roots;
• machine size and expected production time;
• gate, slope, transport, handwork, and ground protection;
• public work-zone or traffic control;
• utility ticket administration and private locating;
• hand or vacuum exposure by qualified parties where lawful and suitable;
• obstruction allowance;
• chip and soil volume;
• loading distance and haul access;
• disposal fee and travel;
• imported soil, seed, sod, mulch, and erosion control;
• permits, inspections, and specialist support;
• crew, spotter, and supervision;
• weather remobilization and no-access risk.

Example price structure:

State tax treatment, payment timing, deposit, permit charges, card fees, and price validity only as allowed by applicable law. Residential landscaping or tree work may fall within state or local home-improvement definitions. California’s CSLB, for example, tells consumers that covered home-improvement contracts over its stated threshold must be written and that scope, cleanup, permits, price, payment schedule, changes, and cancellation rights must be handled in the required form. New York General Business Law §771 likewise prescribes terms for covered home-improvement contracts. These are examples; determine the rules that apply to the property, contract amount, contractor, and work type.

Use objective change-order triggers

List discoveries that can change price or method:

• measured stump differs from the quoted record because it was concealed;
• customer adds depth, roots, area, hauling, or restoration;
• work must stop for an unknown or conflicting utility;
• a private locator, facility owner, arborist, engineer, plumber, electrician, or other specialist is required;
• embedded metal, concrete, significant rock, contamination, or connected root mass appears;
• access route or gate differs from the surveyed condition;
• soil is too wet or unstable for agreed access;
• permit conditions require added work;
• chip or soil volume exceeds the included measured limit;
• customer requests a different finish or planting objective;
• the approved work area crosses a property boundary or protected-root area.

A change order should identify the affected stump, observed condition, safety status, revised scope, price or unit rate, schedule effect, restoration effect, and authorization. Photograph the condition before covering or altering it.

Do not charge merely because production took longer than estimated when the fixed-price scope and assumptions remain true. The estimate allocates ordinary productivity risk to the contractor unless the agreement says otherwise.

Define scheduling and readiness

Ground work depends on more than a calendar slot. Make scheduling contingent on observable readiness:

• signed acceptance and any lawful payment;
• ownership and access authority;
• permits issued and conditions reviewed;
• exact stump and root areas marked;
• valid 811 ticket and completed responses;
• private-facility review complete;
• conflict-resolution plan approved;
• customer items and vehicles removed;
• gate, keys, pets, tenants, and alarms coordinated;
• weather and soil support safe machine access;
• public work-zone approvals in place;
• restoration materials available.

Give a service window, not a false minute-by-minute guarantee. State how weather, emergency tree work, utility delays, permit holds, and unsafe soil affect rescheduling. If a crew mobilizes and the site is not ready, a disclosed no-access or remobilization charge may apply subject to the contract and local law.

Document completion stump by stump

Use the inspection report and completion sign-off to record the finished envelope, material disposition, restoration delivered, settlement instructions, visible damage, and open work by stump ID. If embedded metal, concrete, unknown piping, unexpected roots, or access conditions change the safe scope, follow the hidden-condition workflow and issue a change order. The tree-removal quote guide provides related wording when removal, rigging, traffic, or wood handling is also part of the job. Keep the employer's operational controls in the job hazard analysis, not in a customer disclaimer.

Closeout should make the result testable.

For each stump, record:

• stump ID and location;
• work date and crew;
• machine or method;
• permit and locate references;
• pre-work marks and private-locate status;
• horizontal envelope completed;
• depth reference and verification readings;
• roots completed and omitted;
• obstruction or utility limitation;
• estimated or measured material left, spread, or hauled;
• backfill material and quantity;
• restored area and finish;
• photos before grinding, after depth verification, after backfill, and at final finish;
• damage, near miss, or stop-work event;
• customer care instructions;
• open items and responsibility.

Do not photograph only the final topsoil. Once the pocket is filled, the actual grinding depth and hidden limitations are difficult to verify.

Example completion note:

S-01 ground within the marked 6-foot circle. Verified 8–9 inches below the established lawn reference at north, east, south, and west points before backfill. R-01 completed for 9 marked feet. West flare omitted 20 inches from blue utility marks under the site-specific safe-dig plan; customer accepted the documented limitation. Loaded 3 cubic yards of generated grindings; no pre-existing bed material hauled. Placed 1.5 cubic yards screened topsoil and restored 38 square feet with specified seed and straw. Watering transferred to customer under attached instructions.

Sample scope language

The following is a drafting model, not a substitute for local legal or safety review:

Stump S-01. Contractor will grind the stump shown in Photos 1–3 within the white 6-foot-diameter circle. Fixed price is based on a 25 × 22-inch cut face and 39 × 34-inch visible flare. Contractor will target 8 inches below the undisturbed lawn grade established at four perimeter stakes, after removing loose material at each measurement point. Roots outside the circle and all wood beneath the target depth are excluded except R-01.

Root R-01. Contractor will grind the painted surface root for 9 linear feet from S-01 to the blue endpoint stake, to a target of 4 inches below adjacent lawn grade. Work stops before the sidewalk and outside every required utility tolerance zone. Buried, branching, or continuing roots are excluded.

Utility readiness. Contractor is the excavator of record and will submit the state 811 request for the full marked work area. Work begins only after the applicable waiting period, active-ticket requirement, and required positive responses are satisfied. Customer will disclose known private facilities and provide records. Price includes a private-locate allowance of $___; additional locating or facility-owner support requires written approval. Powered grinding will not occur inside a governing tolerance zone unless facilities are lawfully exposed or protected and a documented safe method permits the work.

Material and finish. Price includes removal of up to 3 cubic yards of generated loose grindings, placement of up to 1.5 cubic yards of specified screened topsoil, finish grading of up to 40 square feet, and application of the named seed and straw. Additional generated grindings are $___ per measured cubic yard with approval. Pre-existing soil, rock, concrete, mulch, trash, and contaminated material are excluded. Customer begins and maintains watering under the attached instructions.

Unknown conditions. Embedded metal, concrete, significant rock, unknown facilities, concealed structures, contamination, and access conditions materially different from the site record trigger stop-work and written change procedures. Contractor may leave an affected portion unground where continuing would violate law, permit conditions, manufacturer instructions, or the site safety plan; the parties will document the resulting scope and price adjustment.
