Fill-dirt usually weighs about 1.2 to 1.6 tons per cubic yard depending on moisture and compaction. To calculate: multiply area (sq ft) by depth (ft) to get cubic feet, divide by 27 to get cubic yards, then multiply by your chosen tons/yd3 value (for example 1.4) to get tons. Order 5-10% extra to allow for settling and spreading.

Uncompacted or organic-rich fill-dirt can settle, heave, or erode in Potomac's freeze-thaw cycles and during heavy rain events. For best results, use clean, well-graded fill-dirt, compact it properly, and provide good surface and subsurface drainage to limit saturation and frost action. For structural or sloped areas, consider engineered or granular fill and erosion controls rather than loose topsoil.

Potomac falls under Montgomery County, MD rules, which may require permits, engineered fill, or inspection for significant grading, structural foundations, or public utility work. For simple yard grading or leveling you often do not need a permit, but for driveways, foundation work, or major backfill you should check Montgomery County Permitting Services and follow any compaction testing or engineered-fill requirements. When in doubt, contact the county or your project engineer before ordering material.

Compact fill-dirt in 4 to 8 inch lifts using a plate compactor or vibratory roller, aiming for good density (contractor targets often reference 90%+ of standard Proctor for structural fills). For homeowners, renting a plate compactor and compacting in multiple passes works well for most projects. Use geotextile fabric on slopes and where soft subgrades are present to separate soils, reduce migration, and help control erosion; combine fabric with drainage measures and terraces on steeper slopes.

Some immediate settlement occurs after placement, and secondary long-term settlement can continue for months, especially over compressible or wet underlying soils. For light landscaping expect a short wait and periodic topping, but for building pads, driveways, or structures you should use engineered fill, compaction testing, and follow a geotechnical or building inspector's guidance before construction. If you need help specifying engineered fill or testing, Hello Gravel can connect you with local suppliers and contractors.
