Site Grading and Building Pad Preparation in Sacramento

Grading is how a lot becomes buildable. Before a foundation, slab or shop can go in, the ground has to be cleared, shaped and brought to the right elevation, and water has to have somewhere to go. Site grading and pad preparation covers that work, from stripping the surface to leaving a firm, shaped pad ready for the next trade.

When you need grading and pad preparation

You typically need this work when you are building a new home, a detached garage or shop, an accessory dwelling unit, a barn, or a large addition. You may also need it when an existing yard slopes toward a structure, when a lot has to be leveled for a driveway or parking area, or when a previous owner left uneven fill that needs to be reworked.

How a typical job runs

Every site is different, but most grading jobs follow the same order.

1. Site walk. We look at the lot, access, existing vegetation, slopes and any plans you have. This is where we talk through your goals and flag anything that could change the scope.
2. Utility locating. California law requires contacting USA North 811 before digging, at least two working days ahead. See our guide on calling 811 before you dig in California. Private lines, such as irrigation, septic and well lines, are not always marked by 811, so tell us what you know.
3. Layout and erosion control. Pad corners and elevations are marked, and any needed sediment control is set before soil moves.
4. Stripping and cut and fill. Topsoil and vegetation are removed, then soil is cut from high areas and placed in low areas. Extra material can be hauled off, and shortfalls can be made up with imported fill. See material hauling, import and export.
5. Shaping and compaction. The pad is shaped, and fill is compacted when the plans or engineer call for it.
6. Cleanup. We leave the site graded to drain, with loose debris removed.

Local conditions that matter

Soil is the biggest variable around Sacramento. Clay-rich, expansive soils are common on the valley floor, and they move as they wet and dry, so pad design often matters more than people expect. In parts of east and south Sacramento County and the lower foothills, cemented hardpan layers can make digging slower. In the Folsom, El Dorado Hills, Rocklin and foothill areas, granite, decomposed granite and boulders are common, which affects how deep you can cut and what material can be reused.

Low-lying areas near the rivers and the Delta side can have shallow seasonal groundwater, and levee-protected areas and FEMA flood zones can limit how much a site may be raised or reshaped. The wet season, roughly November to April, affects scheduling and brings erosion control and stormwater requirements.

What to have ready for an estimate

• The address or parcel number and the approximate size of the area
• Any site plan, grading plan, soils report or engineer’s recommendations
• What you plan to build and where
• Known obstacles: trees, fences, septic, well, irrigation, overhead lines
• Your target start window

The list above is typical scope. The final services and scope are confirmed per job in your written estimate. When you are ready, contact us to request one.
