Before grinding, Brown Bear Land Services reviews or requests an SC811 ticket, Positive Response status, and available markings. Because estimates may be prepared before utility locating is completed, they assume no underground facility overlaps or conflicts with the stump or required grinding area unless the conflict is already known. If later utility markings show a conflict, the estimate or scope may be revised. Brown Bear may also limit the grinding depth, modify the work area, postpone the work until the conflict can be resolved, or decline the affected stump. Safety and utility-clearance requirements take priority over the standard grinding depth and schedule. A marked or otherwise verified facility directly beneath a stump may result in that stump being declined if its location and the required clearance cannot be safely confirmed.
