TREE RETENTION
WORKSHEET
1. Total number of trees over 6" in diameter' on }project site: 1. (0 l trees
2. Deductions: Certain trees are excluded from the retention calculation:
Trees that are dead, diseased or dangerous2 trees
Trees In proposed public streets 1 l trees
Trees in proposed private access easements/tract-5 trees
Trees In critical areas3 and buffers D trees
Total number of excluded trees: 2. 2 (o, trees
3, Subtract rine 2from lire T: 3- _ _ -5 trees
4. Next, to determine the number of trees that must be ratained' , multiply line 3 by:
0.3 in zones RC, R-1, R-4, or R•8
0.1 in all other residential zones
0.05 in all commercial and industrial zones 4. 23 trees
5. List the number of 6" or larger trees that you are proposings to retains:
5. 1- I trees
6- Subtract fine 5 from line 4 for trees to be replaced: 6. trees
if tine 6 Is less then zero, stop here, No roplamment trees are required),
7. Multiply line 6 by 12" for number of required replacement inches:
7. Z inches
14062/p02
6. Proposed size of trees to meet additional planting requirement:
Mlnfrrtum 2" caiipertrees required) 8. inches
per tree
9. Divide line 7 by line 8 for number of replacement trees':
tf remainder is ,5 cr gredl0r, ewrid up, to the next whole number)

Inches tlf street trees, Inches or tretas added tD orltical vreaslbutfers, and inches of trees retained onsite that
