Fill-dirt in Napavine, WA

Local fill-dirt prices in Napavine typically range from about $15 to $30 per cubic yard delivered, which roughly equates to $12 to $25 per ton depending on density and compaction. Tailgate spreading is offered at the driver's discretion and may add a separate fee or be unavailable; request it at checkout and budget extra if you need spreading. Prices depend on supplier, distance, seasonal demand, and whether you need engineered or screened fill, so get a quote for your zip code on Hello Gravel to see exact pricing and minimums (minimum order 3 tons).

For driveway base, West Washington contractors commonly use a layered approach: compacted structural fill or pit-run fill as the bulk lift, topped with 3/4u0022 minus or crushed base rock for the wearing surface. For lot raises, contractors often use select or structural fill (clean, well-graded material) or a sandy gravely mix to aid drainage; engineered or imported fill is used when specs require it. Because materials vary by supplier and local geology, talk to Hello Gravel about the right mix for compaction, drainage, and permit requirements for your Napavine project.

Assuming a typical one-car driveway width of 9 feet, volume = length x width x depth = 50 ft x 9 ft x 0.5 ft = 225 cubic feet, or about 8.3 cubic yards. Contractors usually add 10% to 15% extra for compaction and settlement, so plan to order about 9 to 9.5 cubic yards. In tons that is roughly 11 to 14 tons depending on how dense the fill is once compacted; Hello Gravel’s minimum order is 3 tons so a single delivery will cover this job, and we recommend confirming exact quantities with our material calculator and your contractor.

Permit requirements depend on the scope of the work: small landscape fills often do not require engineered fill, but any grading that affects drainage, lot elevation for development, or support for structures frequently triggers permit conditions. For foundations, retaining walls, driveway approaches to the public right-of-way, or significant lot raises, Napavine or Lewis County commonly require engineered fill or compaction testing and a certificate from a geotechnical engineer. Before ordering fill-dirt, contact Napavine City Hall or Lewis County Community Development to confirm permit rules for your specific address and include those specs when requesting quotes so suppliers can match the material and testing needs.

Napavine’s wet weather means moisture content is a big factor: fill-dirt that is too wet is hard to compact properly and may settle more, while very sandy mixes drain better but can migrate if not contained. Contractors compact in thin lifts and schedule work during drier windows when possible; using well-graded structural fill, proper drainage layers, and geotextile where needed helps prevent saturation and long-term settlement. Discuss local conditions with your supplier and contractor, and consider compaction testing or using a low-permeability cap where moisture control is critical.
