Measure the area (square feet) and the desired depth (in inches), convert depth to feet, then multiply to get cubic feet and divide by 27 to get cubic yards. In this region, plan on about 1.2 to 1.4 tons per cubic yard for loose fill-dirt; for example, raising 1,000 sq ft by 3 inches is roughly 9.25 cubic yards or about 11 to 13 tons. Order about 5-10% extra to account for compaction and settlement, especially in wet West Washington soils.

For structural fills, building pads, or work near property lines you will likely need permits and engineered plans from Sedro-Woolley or Skagit County, and compaction testing is commonly required for foundation support. Requirements vary by project size and use, so contact the Sedro-Woolley Building Department or Skagit County Permitting to confirm rules and testing standards before ordering material. Hiring a civil engineer or local contractor familiar with county requirements is a good step for larger projects.

In Sedro-Woolley’s wet climate, non-organic, well-draining fill-dirt performs better than topsoil because it resists settling and holds compaction; organic-rich materials and loose peat should be avoided. On slopes, combine engineered fill with drainage measures (subdrains, swales), erosion control (mulch, seed, erosion blankets), and, when needed, retaining walls or geotextile to prevent movement. Always compact in lifts and keep runoff management in mind during rainy seasons.

Use fill-dirt for bulk grading and raising low spots but not as a final driving surface because it compacts but can retain moisture; crushed rock is the preferred choice for driveway bases and surfaces because it drains and locks together. Reserve topsoil for planting beds and lawn areas where organic matter and nutrient content matter. A common approach is compacted fill-dirt for grade, then a compacted crushed-rock base and a crushed-rock or asphalt surface for driveways, with topsoil placed only where plants will grow.

Local contractors typically place fill in 4 to 8 inch lifts, moisture-condition each lift, and compact using plate compactors or rollers to meet specified densities. They avoid spreading during heavy rain, test representative lifts when required, and keep organics separated from engineered fill. If you want spreading or compaction services, request them early—Hello Gravel can deliver material but spreading and compaction are usually provided by specialized contractors.

Fill-dirt itself doesn’t “expire,” but expect settlement in the first year as material densifies; low spots may need spot-filling or regrading after winter rains. For driveways, a proper crushed-rock surface over the fill will last much longer, while landscaped areas need topsoil and vegetation to reduce erosion. Regularly check drainage, repair erosion, and add material to settled areas as needed.

Yes — the Skagit Valley and surrounding areas can include alluvial deposits, high water tables in low-lying parcels, and pockets of organic material or peat that are unsuitable as structural fill. Have your site inspected or request a simple infiltration or probe check before ordering large quantities; for sensitive sites, a geotechnical recommendation will tell you what type of fill to use and whether subdrains or engineered fill are needed.
