Contractors typically charge for debris removal based on a unit price for volume (cubic yards) or weight (tons).  The specific method of charging may vary depending on the contractor and the nature of the debris being removed.  Here are some common approaches:

• Volume-based pricing: Contractors may charge based on the volume of debris being removed, typically measured in cubic yards.  They may use equipment such as loaders or trucks to estimate the volume and determine the price accordingly.It is worth noting that FEMA encourages Applicants to procure branch or limb removal from trees on a one-time charge per tree basis, rather than a unit price per limb or branch.  This approach is considered more cost-effective.
• Weight-based pricing: In some cases, contractors may charge based on the weight of the debris being removed, measured in tons.  They may use scales or other weighing methods to determine the weight and calculate the price accordingly.
• Per tree or stump pricing: For hazardous limbs, trees, and stumps, contractors often charge a price per tree or stump based on its size.  The size may be measured by diameter or other relevant factors.
