Modesto pricing: $8–$13 per sq ft. A 12x40 ft RV pad (480 sq ft) in Modesto typically runs $4,000–$6,500 at 5–6 inches thick; widening a driveway by one car width is often $2,500–$4,500 plus any approach permit.

Build for the weight: 5 to 6 inches with rebar on a compacted base, doweled or jointed where it meets the existing driveway, and sloped away from the house and the neighbor. Gates may need widening and sprinklers moved.

Check the rules on where RVs, boats and trailers can be kept on your lot before pouring; Modesto's zoning code and many HOAs regulate it, and the City's planning staff can confirm for your parcel.

If the widened driveway reaches the street beyond the existing curb cut, the approach and curb work needs an encroachment permit from Land Development Engineering.
