Classifying storm debris for a clean-up bid: vegetative, C&D, and white goods

If your scope of work lumps everything into one "debris removal" line item, your contractor's price is going to be wrong in one direction or the other. FEMA's Public Assistance Category A debris work, and most private haulers who've worked a Category A job, all price by debris type, because each type moves through a different truck, a different site, and a different disposal cost. Get the split wrong before the bid goes out and you're either overpaying for comingled loads or fighting a reimbursement dispute six months from now.

Here's the three buckets you're actually working with.

Vegetative debris

Limbs, trunks, brush, root balls, the stuff a wind event generates by the mile along every residential street. This is usually your highest volume and lowest per-cubic-yard cost, because it can go straight to a grinding site and get reduced to mulch, cutting the net haul volume by 4:1 or 5:1 after processing. Most contracts price vegetative debris separately from everything else precisely because that reduction ratio changes the economics of the whole haul.

The catch is that vegetative debris collection sites fill fast after a windstorm, and a reduction site has to be sited, permitted, and staffed before the first load shows up. If your volume estimate for vegetative debris is off by even 20%, you're either paying for an oversized site that sits half empty or scrambling to open a second one mid-contract.

C&D debris

Construction and demolition debris covers roofing material, siding, lumber, drywall, fencing, and the structural pieces of anything that came apart in the wind. This is the category that gets expensive fast, because C&D can't be ground down the way vegetative debris can. It goes to a landfill or a C&D-specific disposal facility, and tipping fees there run well above a vegetative reduction site.

C&D is also where mixed-load disputes happen most often. A load that's mostly roofing shingles with a few tree limbs mixed in gets classified, and priced, as C&D, not as vegetative with a discount. Debris monitors at the collection point are trained to catch this, but the fewer surprises in your pre-bid volume estimate, the fewer change orders you're signing during the response.

White goods

Refrigerators, washers, dryers, water heaters, AC units. Small category by volume compared to the other two, but it needs its own line item because of Freon and other refrigerants. Appliances with refrigerant lines have to go through recovery before they can be crushed or recycled, which means a separate handling step and usually a separate subcontractor or certified technician on-site. A clean-up bid that doesn't carve out white goods separately either underprices the Freon recovery work or, worse, skips it and creates an EPA compliance problem for whoever holds the contract.

Why the split matters for sizing the bid

A logistics officer sizing a contract off a windshield survey is making a visual call, street by street, on what type of debris is piled where. That works, but it's slow, it's weather-dependent, and it's only as good as the coverage you can physically drive before the bid has to go out. The split between vegetative, C&D, and white goods has to happen somewhere, and doing it from a vehicle means doing it twice (once for the bid, once again when the monitors start logging actual loads).

Running that classification off a dated image of the affected area, instead of waiting on a drive-through, lets you size each debris type's volume before a single truck moves, which is the whole point of a debris and structure map built from post-storm imagery. It won't replace the monitor at the collection site counting cubic yards off a load ticket, but it gives you a defensible starting number for each category before the contract is signed, instead of after.

If you're pricing a clean-up contract and need that first-pass volume split by debris type, Debris Mapping runs off the imagery as soon as it's available after the storm passes.
