You want the property cleared for another use
Ask the scope to describe removal of trunk sections, branches and chips rather than using only a broad cleanup phrase. Include stump residue and final surface restoration if those matter to your plan. The destination and lawful handling are questions for the contractor to clarify, not something the homeowner should discover after an unexpected pile is left in the access route.
Notice next: Request a description of the finished site and any material that will remain. Compare bids only after the cleanup outcomes match.
