Fill Dirt in Davis-Monthan, AZ

Delivery fees in the Davis-Monthan/Tucson area vary by supplier, distance, and tonnage. Many Hello Gravel orders qualify for free delivery, but small orders or long hauls commonly incur fees—typical residential deliveries range from $0 to about $150 depending on access and distance. We recommend checking the checkout price or requesting a local quote for the most accurate fee.

Local suppliers around Tucson and Pima County provide most fill-dirt for Davis-Monthan customers, and deliveries are typically handled by tri-axle dump trucks from local haulers. Most suppliers deliver within a 20–50 mile radius of the city, though availability and radius depend on the supplier; Hello Gravel connects you to nearby vendors and shows delivery options for your zip code.

Use a simple two-step method: 1) Calculate cubic yards: (Area in square feet * depth in inches / 12) / 27. 2) Convert to tons: multiply cubic yards by an approximate factor of 1.2 to 1.4 tons per cubic yard (we use ~1.3 tons/cy as a typical estimate for fill-dirt in the Tucson area). For example, 1,000 sq ft raised 3 inches is about 9.3 cubic yards, or roughly 12 tons.

Fill-dirt is fine for raising grades, backfilling, and creating structural fills, but it is not ideal as a finished surface in hot, arid climates because it can produce dust, shrink, and erode. In Davis-Monthan you should compact fill-dirt properly, add a surface cap (gravel or decomposed granite) for traffic areas, and consider dust-control measures to reduce problems from heat and wind. For finished driveways or pathways, crushed rock or decomposed granite are generally better choices.

For driveways and pads, choose well-graded fill with a mix of sand, fines, and small gravels that compacts well and provides a stable base under a finished surface. For general landscaping or berms, a looser, finer fill-dirt with more topsoil or fines can be acceptable but should still be compacted in lifts. Avoid high-organic topsoil as structural fill; always tell your supplier the intended use so they can recommend an appropriate blend.

Rates vary by job size and access, but spreading is commonly priced either by the cubic yard ($8–$25 per cubic yard) or by the hour ($40–$80 per hour), while compaction (plate tamper or roller) is often $0.50–$1.50 per square foot or billed by the hour for machinery. Get local bids because tight access, lot slope, and lift thickness all affect labor and equipment needs. Hello Gravel can help estimate volumes so you can request accurate contractor quotes.

Fill-dirt is inexpensive and good for bulk filling and grading, but it does not drain as well and creates more dust than crushed rock or decomposed granite (DG). Crushed rock and DG provide better surface stability, drainage, and dust control for driveways and high-traffic areas, so they are typically preferred as a finished surface in the Davis-Monthan desert climate. Consider using fill-dirt for raising grade and then capping with crushed rock or DG for the finished surface.

Fill-dirt used as structural fill can last for decades if properly placed in lifts and compacted, but exposed fill-dirt will settle, erode, and create dust over time in a hot, dry climate. Expect occasional regrading or top-ups after heavy rains or wind events, and plan on applying a surface cap or vegetation to reduce dust and erosion. Regular maintenance includes spot regrading, compaction of disturbed areas, and dust suppression when needed.

Permitting depends on the scope of work and local regulations; small grading or minor backfill rarely needs a permit, but significant grade changes, retaining walls, or structural pad work often require review by Pima County or the City of Tucson building and planning departments. Check local codes before ordering large volumes (especially if raising land by more than a few inches or changing drainage patterns). If you are unsure, contact your local building department or Hello Gravel's team for guidance before placing a big order.

Control measures include compacting the fill in lifts, capping exposed areas with gravel or decomposed granite, installing geotextile fabric on slopes, and using dust-binding agents or polymer stabilizers for high-traffic areas. For weed control, lay a weed barrier where appropriate and consider a thin layer of topsoil with drought-tolerant seed or hardscape on top. Proper slope grading and drainage swales will also minimize erosion in heavy rains.

Calculate cubic yards first: (Square feet x depth in inches / 12) / 27. Multiply cubic yards by an estimated weight per cubic yard for fill-dirt (commonly 1.2–1.4 tons/cubic yard) to get tons. Example: to raise 500 sq ft by 4 inches: (500 x 4 / 12) / 27 = 4.63 cubic yards, which is roughly 6–7 tons using 1.3 tons/cy.

Contractors often recommend geotextile fabric for unstable soils or slopes, mechanical compaction in 6- to 8-inch lifts, and a cap of crushed rock or DG for finished surfaces to reduce dust and improve drainage. Other common additions are drain rock for subdrains, soil stabilizers for dusty areas, and small amounts of clean sand or gravel mixed in to improve compaction. When ordering through Hello Gravel, note these preferences in Order Notes so suppliers can suggest appropriate mixes or add-ons.
