NOTES:
1. Leave critical areas (such as flood plains, steep slopes and
wetlands) with desirable trees in their natural condition or only
partially cleared.
2. Select trees to be preserved before siting roads, buildings or
other structures.
3. Minimize trenching in areas with trees. Place several utilities
in the same trench.
4. Prohibit or restrict access to tree protection zones(TPZ). Post
"Keep Out" signs on all sides of fencing and do not store
construction equipment or materials in TPZ.
5. Monitor trees using a professional or train your staff to monitor
tree health during and after construction on a regular, frequent
basis.
6. Assign a crew member to weekly TPZ fence integrity checks.
Repair and replace TPZ fencing as needed.
MAINTENANCE:
1. Prune any damaged trees. In spite of precautions, some
damage to protected trees may occur. In such cases, repair any
damage to the crown, trunk, or root system immediately.
2. Repair roots by cutting off the damaged areas and painting
them them with tree paint. Spread peat moss or moist topsoil
over exposed roots.
3. Repair damage to bark by trimming around the damaged area,
taper the cut to provide drainage and paint with tree paint.
4. Cut off all damaged tree limbs above the tree collar at the trunk
or main branch. Use three separate cuts to avoid peeling bark
from healthy areas of the tree.
