Excavation Grading Experts in Redding

Residential Lot Preparation

Building a home on raw land in Northern California starts with a correctly graded pad — we establish the cut-and-fill elevations, compaction spec, and drainage slope that your foundation contractor needs before the first concrete is poured.

Commercial Site Work

Commercial builds demand tighter grade tolerances and faster cycle times — Lee One Construction delivers engineered-grade accuracy on commercial lots across Shasta County, coordinating with structural engineers and site supers to keep the project schedule intact.

Building Pad Construction

A pad that settles unevenly after construction means cracked slabs and failed inspections; we compact building pads in lifts to the density specified in the soils report, then document the process for the county.

Road Grading and Preparation

Rural driveways, ranch roads, and access routes on Northern California parcels need proper crown, grade, and base compaction — we build and restore road surfaces that shed water correctly and hold up through the wet season.

Drainage Channel Formation

Correctly formed drainage swales and channels redirect surface runoff away from structures and septic systems; we cut, shape, and grade drainage corridors that work with the natural topography of your property rather than against it.

Government and Infrastructure Projects

Lee One Construction holds CSLB #1063228 and carries the insurance and bonding required for public and government work — we have completed excavation and grading projects for infrastructure, utilities, and civic projects across Northern California.

25 Years of Northern California Ground Conditions

Shasta County sits on a geologically active landscape where volcanic basalt and andesite fragments appear at shallow depths, often without warning. Equipment selection matters — a contractor who does not know the ground may under-specify the machine and blow the schedule on the first hour of digging. We know which areas of the county run rock-shallow, and we bring the right iron from the start.

The valley-floor soils around Anderson and Redding contain expansive clays that swell with moisture and shrink in summer, a cycle that destroys foundations, buckles slabs, and collapses improperly compacted fills. We account for clay behaviour in every cut-and-fill calculation, specify appropriate over-excavation depths, and use moisture conditioning during compaction to limit long-term settlement.

The foothill areas east of Redding and across much of Shasta County present decomposed granite — a material that reads as stable until it gets wet, at which point it flows. We grade DG zones with the drainage slope and surface treatment that prevent erosion and protect the finished grade through the wet season.

The flat agricultural areas of the Sacramento Valley near Cottonwood, Corning, and Gerber carry alluvial soils with layered permeability — high-clay lenses beneath sandy topsoil create drainage problems that only show up after heavy rain. Twenty-five years of working these soils means we diagnose subsurface drainage conditions before excavation begins, not after the drainage system fails its first winter test.
