A live oak beside a new foundation
- Problem
- The site plan puts a new building a few yards from a mature live oak. The owner wants the tree kept, and the schedule can’t slip.
- Assessment
- We map the critical root zone, then run an air spade along the planned excavation line to find the major roots without cutting a single one.
- Reasoning
- Most construction damage happens underground: severed roots, compacted soil and changed grades. The roots have to be found before the excavator finds them.
- Work performed
- A fenced tree protection zone, clean root pruning only where the foundation crosses, arborist chips over the root zone and a soil program to regrow roots, with an inspection at each construction phase.
- Result
- The oak stays, the building goes up on schedule, and the project team has a written tree protection plan for its file.
- Methodology
- ANSI A300 Part 5 (trees during site development and construction) · Air-spade root investigation
