Subdivision Mass Grading and Building Pad Preparation in Wheatland, CA
Precision Site Work for Wheatland's Fast-Growing CA-65 Residential Corridor
Topsoil Strip & Rough Cut/Fill
Step 1 & 2: We remove the top 6 to 12 inches of organic soil from the building footprint and stockpile it for landscaping later. Next, our Cat D6 dozer establishes the rough subgrade, moving material from high spots to low spots to keep import costs down.
Fill Compaction to 95% Density
Step 3: Import fill goes in at 6-inch layers. We compact each layer to 95 percent modified Proctor density, meeting the exact Yuba County building standard before any structural work begins.
Base Rock & Laser Grade Finish
Step 4 & 5: We place 4 to 6 inches of Class II aggregate base over the subgrade for a firm, dry curing surface. Then, our motor grader with sonic averaging levels the final surface within plus or minus one-eighth inch, ready for concrete forms and county inspection.
Equipment Deployed on Wheatland Projects:
