Rough grading and pad prep for Del Paso Heights infill
Most grading here supports the neighborhood's infill and ADU push on flat North Sacramento lots.
Del Paso Heights is largely flat valley ground, which is good news for building — but a flat lot still has to be deliberately shaped into a pad that carries a structure and sheds water. The grading we do along Marysville Boulevard, Rio Linda Boulevard, and Grand Avenue is mostly rough grading and pad prep for new infill homes and accessory dwelling units on vacant, cleared, or just-demolished lots. That means cutting and filling to establish the pad at the right elevation, bringing the ground to a uniform grade, and compacting it so the finished surface is something a foundation can sit on with confidence. On these individual infill lots the work is tailored parcel by parcel rather than mass-graded like a subdivision — we set the pad relative to the street, the neighbors, and where the driveway and utilities land. Done right, the grading phase hands your builder or ADU installer a pad that is level, compacted, and draining, so they are framing instead of fixing dirt.
Grading flat clay ground so water moves the right way
On a flat lot with clay soil, drainage is the problem grading has to solve.
The expansive clay under Del Paso Heights swells when wet and shrinks when dry, and because the ground is flat, water does not leave on its own — it sits. Standing water on clay is exactly how you end up with a soft, unstable pad, seasonal ponding, and moisture working against a new foundation. So the grading is not just leveling; it is building a deliberate positive slope that carries water away from the pad and off the lot toward the street or an approved outfall. We set finished grades so the parcel sheds water in the wet Sacramento winters, keep the fall consistent so there are no low spots that collect, and compact the clay to a stable density so the graded surface holds its shape. Getting the drainage right at the grading stage is far cheaper than chasing a wet pad or a ponding backyard after the concrete is poured — and on this flat, clay-heavy ground it is the single most important thing grading accomplishes.
Post-teardown and larger-parcel grading
A lot of Del Paso Heights grading happens right after a demolition or on the neighborhood's deeper parcels.
When a failed structure comes down, what is left is rarely ready to build — there is a disturbed footprint, backfilled slab and utility trenches, and loose ground that has to be brought back to a stable, uniform grade. We regrade those cleared lots as a natural continuation of the teardown, compacting the clay in lifts so the new pad does not settle where the old foundation was. On the larger and semi-rural parcels toward the Robla and Rio Linda edge, grading also covers driveways and access, shaping a stable, well-draining route in from the road, plus rough site grading across a bigger footprint. Those deeper lots bring their own drainage considerations — we grade so runoff is managed toward the road or an approved point rather than pushed onto a neighbor. Whether it is a tight infill pad or a larger parcel with a driveway to cut, the constant is the same clay: it has to be compacted and shaped correctly, or it moves.
Permits, engineered pads, and what grading costs here
Grading in Del Paso Heights follows City of Sacramento rules, and cost tracks the earthwork the lot needs.
Grading is permitted through the City of Sacramento once it crosses the city's cut, fill, or disturbed-area thresholds, and where the work is tied to an ADU or new build it is coordinated with those plans and the project's soils report. For a pad that will carry a structure, compaction is done in lifts to the density your engineer specifies and documented, so the pad is genuinely engineered rather than just smoothed over. Cost comes down to the earthwork involved: how much cut and fill the lot needs, the volume of import fill required to bring clay to grade, whether a driveway or larger parcel is in scope, drainage complexity on the flat ground, and haul distance for spoils. A simple pad on an already-cleared, near-level infill lot sits at the low end; a larger parcel needing significant fill, a driveway, and drainage work runs higher. As with the region's site prep, expect the pad-and-grading portion to fall within a low five-figure envelope on most residential jobs — but we quote a real range after walking the lot and reading the plan, not before. On flat clay we also confirm where the lot legally drains before setting finished grades, so the pad sheds water to an approved point rather than toward a neighbor — a detail the City reviews on infill and ADU grading. Settling that on paper before the dirt moves avoids a redo when the inspector walks the finished pad.

Frequently asked questions
How much does grading cost in Del Paso Heights?
It tracks the earthwork the lot needs. A simple pad on an already-cleared, near-level infill lot sits at the low end; a larger parcel needing significant fill, a driveway, and drainage work runs higher. The cost levers are cut and fill volume, import fill to bring clay to grade, driveway or larger-parcel scope, drainage complexity, and haul distance. We quote a real range after walking the lot and reading the plan.
Do I need a grading permit in Del Paso Heights?
Often, yes. The City of Sacramento requires a grading permit once the work crosses its cut, fill, or disturbed-area thresholds, and grading for an ADU or new build is coordinated with those plans and the soils report. We handle the permitting as part of the scope and let you know early whether your lot triggers it.
Can you grade a pad to my engineer's specification?
Yes. For any pad that will carry a structure we compact native ground and import fill in lifts to the density your soils engineer specifies, and document it. On Del Paso Heights' expansive clay, compacting to spec is what keeps the finished pad stable under the new foundation rather than settling later.
How do you keep water off a flat clay lot after grading?
We build a deliberate positive slope that carries water away from the pad and off the lot toward the street or an approved outfall, keep the fall consistent so there are no low spots, and compact the clay to a stable density. On flat, clay-heavy North Sacramento ground, managing drainage at the grading stage is the most important thing the work accomplishes.
Can you grade the lot after you demolish the house?
Yes, and it is a natural continuation of the teardown. Once a structure is down there is a disturbed footprint, backfilled trenches, and loose ground; we regrade and compact the clay in lifts so the cleared lot becomes a stable, level, well-draining pad ready for the next build.
