Fill Dirt in Alhambra, CA

Typical delivered prices in the Alhambra area range from about $12 to $35 per cubic yard (roughly $9 to $26 per ton). Final cost depends on supplier, volume, delivery distance, whether the dirt is screened or contains debris, and current local demand. Hello Gravel's minimum order is 3 tons and you can get an exact quote by entering your zip code on our site.

Use 1 cubic yard to cover 9 square feet at 4 inches deep, and plan on about 1.3 tons per loose cubic yard for typical fill dirt. For example, a 20x30 ft patio raised 4 inches needs about 3.3 cubic yards (about 4.3 tons), and a single-car driveway patch 10x20 ft at 6 inches needs about 9.2 cubic yards (about 12 tons). Always add 5-10% extra for settling and compaction.

For driveways and grading around Alhambra, a clean, well-graded fill dirt that is low in organic matter works best. In many cases contractors mix fill dirt with a rock base or cap it with crushed rock for better load-bearing and drainage, especially during occasional heavy rains. Because soils vary locally, ask your Hello Gravel supplier to note regional material characteristics and to recommend a blend if needed.

Hello Gravel connects you with local suppliers around Alhambra and Los Angeles County that deliver fill dirt by dump truck. Our platform shows available suppliers and pricing after you enter your zip code; the company minimum order is 3 tons, while many suppliers and contractors order larger loads (10+ tons) for efficiency. Delivery is typically by tri-axle dump truck and you can request a delivery date at checkout.

Small landscaping fills or leveling for plant beds often do not require a permit, but structural fills, retaining walls, grading that changes drainage, or fills above a certain cubic yard threshold usually do. Check with the City of Alhambra Building Division or your county planning department before major fills; if a permit is required you may also need compaction testing or engineered plans. When in doubt, contact Hello Gravel for supplier recommendations and advise your inspector that you are using locally sourced fill dirt.

Uncompacted fill dirt will typically settle noticeably in the first several months to a year, often a few percent to as much as 10% depending on height and moisture. To minimize settlement, place fill in lifts (6 to 8 inches loose), compact each lift, and aim for a high relative compaction; for structural areas, contractors commonly target 90% or higher of Standard Proctor density. For load-bearing or structural work, ask for engineered fill and compaction testing.

Fill dirt generally has slower drainage than gravels or crushed rock and can hold water if it contains fine silts or clays, which may cause pooling after heavy rains. For Alhambra projects, use fill dirt only where acceptable, slope surfaces to shed water, and combine with coarse base materials or drains where you need good runoff. If drainage is a concern near foundations or slabs, consider adding a granular drainage layer or consult a contractor.

When used as subgrade or for leveling and properly compacted, fill dirt requires minimal maintenance. Exposed fill dirt surfaces used for access or temporary drives will need periodic regrading and may develop ruts or erosion after heavy rain, so expect light maintenance yearly and more after storms. For long-term drive surfaces, topping with crushed rock or pavement reduces maintenance frequency significantly.

Fill dirt is affordable and good for bulk elevation, backfill, and grading but it does not compact or drain as well as crushed rock. Crushed rock is better for driveways and structural base layers because it compacts well and sheds water. Decomposed granite is popular for dry-climate paths and patios for its look, but it is less suitable as structural fill; choose based on whether you need load-bearing strength, drainage, or a finished surface.

For garage slabs and patios, contractors typically remove unsuitable material and install a 4 to 6 inch compacted granular base (crushed rock) on top of properly compacted fill. If fill dirt is used directly under a slab, place it in thin lifts (6 to 8 inches loose) and compact each lift to the specified density; many projects target 90% or higher relative compaction. For structural slabs or where soils are questionable in Alhambra, get a geotechnical recommendation and follow local building department requirements.
