Paver Driveway Around Live Oak: Root Damage Assessment

12-ft wide circular paver drive around large live oak. Inside edge 14 ft from trunk. Canopy extends 20-30 ft. Light grading required. Will this harm tree?

Yes — Root Damage Inevitable

Roots in top 2 ft of soil, extend 1.5x canopy width. Grading damages roots. Tree tolerates ≤25% root loss. >30% = significant foliage dieback.

Damage Calculation

Map root zone (1.5x canopy), subtract graded area. If >30% loss: expect dieback, irrigate heavily for 2 months.

Critical Rules

• No machinery beyond graded area (compaction = more root damage).
• Minimize soil disturbance.

Consider alternative hardscaping (permeable, no grading) or relocating drive.
