Dirt delivery in the Sacramento Valley
Sacramento sits where 2 rivers meet, on alluvial valley floor behind levees, with 4 wet months and 5 dry ones. Raising a pad to a required finished floor elevation is a common reason to buy fill, and in the eastern suburbs the problem changes to hardpan.
Which material do I need in Sacramento?
2 questions decide a Sacramento fill order: elevation and documentation. The city sits on alluvial valley floor behind levees, so raising a pad to a required finished floor elevation is common, and that number comes off a plan rather than out of the air. On the eastern side, through Citrus Heights, Roseville, Rocklin and Folsom, the problem changes to hardpan, and landscape work gets built up over it with 8 to 12 inches of imported soil.
What is the ground under Sacramento made of?
The city proper is built on the floodplain at the confluence of the Sacramento and American rivers, on alluvial silts and loams deposited by those rivers over a very long time. It is soft, workable ground, and it is low. Flood protection and finished floor elevation are live considerations on development here in a way they are not in most inland cities, and raising a pad above a required elevation is a common reason to buy fill.
Out on the eastern side, through Citrus Heights, Roseville, Rocklin, Folsom and El Dorado Hills, you are onto older terraces and hardpan shows up. A cemented claypan layer under the topsoil is a familiar sight to anyone who has dug a post hole out there. It drains badly, roots will not go through it, and it needs breaking or building over rather than ignoring.
What do people buy dirt for here?
California water rules and a 5 month dry summer have pushed a lot of front yards from turf to planted or decomposed granite landscapes, and every conversion is a grading job. Topsoil goes in for the planted areas and fill goes in to build up the contours.
On the valley floor, getting a structure up to a required elevation is a volume of fill question. That number usually comes off a plan or a permit condition rather than out of the air, so start there before you work out yardage, because the elevation sets the volume.
In the eastern suburbs, beds and lawns often get built up over the hardpan rather than dug into it, because breaking it is expensive and the drainage underneath does not improve much when you do. Imported topsoil in volume is the practical answer, usually 8 to 12 inches for beds.
Pool removals here fill the same way they do anywhere: break the shell for drainage, backfill with common fill, budget 60 to 100 cubic yards. Out toward Elk Grove and Rio Linda there are larger rural parcels where levelling, pad building and driveway base work take real volume.
What do the local material names mean?
California uses a different set of words again, and this is the market where the vocabulary matters most, because a term used loosely on a commercial job can cost you a documentation trail you did not budget for.
The term a California general contractor actually uses for material brought onto a site from off it, as opposed to material cut and reused on site. If your plans or your grading permit talk about import, that is what they mean, and it usually comes with a requirement to show where the material came from.
Fill placed to a specification: a defined material, placed in defined lifts, compacted to a defined percentage of a maximum dry density, and tested. It is a method rather than a product. Nothing you buy is engineered fill until it has been placed and tested as such.
The California base course vocabulary. Class 2 aggregate base is the graded material placed under driveways, parking and flatwork to a Caltrans-derived specification. Locally it is often just called baserock. It sits above the fill in the build-up. Ask us before you order whether we can source it for your address.
The local name for the heavy, sticky valley clay that cracks open in the dry season and turns to gumbo in the wet one. It describes a soil rather than a product. If your site is adobe, expect the placing season to matter and expect drainage to be a design problem rather than an afterthought.
A cemented claypan layer sitting under the topsoil across much of the eastern suburbs. It drains badly and roots will not go through it. Anyone who has dug a post hole in Rocklin or Folsom has met it. The practical answer for beds and lawns is usually to build up over it with 8 to 12 inches of imported topsoil, because breaking it is expensive and the drainage underneath does not improve much when you do.
What about grading permits and clean soil documentation?
California is the strictest of the states we run in on where soil comes from and where it goes. On commercial import and export jobs, the state's waste and toxics agencies set the framework for what counts as clean soil and what documentation has to follow it, and a receiving site may require that paperwork before it will accept a load. This almost never touches a homeowner buying 20 cubic yards for a yard raise. It touches every contractor moving material in volume. If your job has that requirement, tell us at the quote stage.
Grading permits are the second input. Sacramento County and the incorporated cities within the region set thresholds above which grading, filling or importing material needs a permit, and the thresholds are expressed in volume and in depth. Check yours before you work out yardage, because if a permit sets a finished elevation then the elevation sets the volume rather than the other way around.
Third is the calendar, and here it cuts both ways. From roughly November through March the valley is wet and dry time is the scheduling constraint, because saturated ground cannot be driven on or compacted. From May through October it barely rains and the problem inverts: material can get too dry to compact without adding water back into it. Neither half of the year is a bad time to buy dirt. They are different problems, and it is worth knowing which one you are buying into.
How does scheduling and access work here?
The Mediterranean climate splits the year cleanly. From roughly November through March the valley is wet and dry time becomes the scheduling constraint. From May through October it barely rains and the problem inverts, because material can get too dry to compact without adding water back into it. Plan which half of the year your job lands in.
Sacramento is also our furthest market from the Texas base, so lead times and haul economics are their own thing here. On a large order that can absorb a longer window, the sourced-for-volume route is often the cheaper way to buy. If your date is fixed, say so early rather than hoping.
How many yards will my Sacramento job take?
A landscape conversion is the common order. Building up planted contours across a 1,200 square foot front yard at 8 inches is about 30 cubic yards, and beds over hardpan at 12 inches run to about 45 cubic yards for the same area.
Raising a pad on the valley floor is set by the elevation on your plan, not by preference. A 50 foot by 60 foot pad raised 18 inches is about 167 cubic yards in place, or 200 to 208 ordered once a compaction allowance is applied. Get the required elevation first, then calculate, then order.
Which cities do we deliver to?

If you are further out into the valley or up toward the foothills, ask before you assume we cannot reach you. It is a haul distance question and the answer is often yes.
Sacramento dirt delivery questions
What is import fill in Sacramento?
The term California contractors use for material brought onto a site from off it, as opposed to material cut and reused on site. If your plans or your grading permit reference import, that is what they mean, and on a commercial job it usually comes with a requirement to document where the material came from.
Do I need a grading permit to bring in fill dirt?
Often, above a threshold. Sacramento County and the cities within the region set volume and depth thresholds above which grading, filling or importing material needs a permit. Check yours before you calculate yardage, because a permit that sets a finished elevation is what sets your volume.
What is hardpan and how do I deal with it?
A cemented claypan layer under the topsoil across much of the eastern suburbs, through Citrus Heights, Roseville, Rocklin and Folsom. It drains badly and roots will not penetrate it. The practical answer for beds and lawns is to build up over it with 8 to 12 inches of imported topsoil rather than trying to break it.
When can you deliver dirt in Sacramento?
Most orders run 1 to 3 days from stock. On very large orders of around 500 loads or more we can source the cheapest supply instead. Sacramento is our furthest market from the Texas base, so lead times run their own way here. From November through March dry time is the constraint. If your date is fixed, say so early rather than hoping.
Do you deliver to Elk Grove, Roseville and Folsom?
Yes. We list Sacramento, Arden-Arcade, Carmichael, Citrus Heights, El Dorado Hills, Elk Grove, Folsom, Rancho Cordova, Rio Linda, Rocklin and Roseville. Further out into the valley or up toward the foothills, ask, because the answer is a haul distance calculation and it is often yes.
Need dirt in Sacramento?
Tell us the address, the cubic yards and the date you need it by. If your address is not on the list above, ask anyway. Coverage is about haul distance.
