Dear Corey:
Thank you for requesting my services. On February 19, 2018, I performed a Visual Risk Assessment
(VRA) for all the significant* trees growing on the site above, as well as the offsite and ROW trees
with canopies that included coverage on the property.
The information gathered and included in this report is a necessary part of the of the redevelopment
process which requires that a Tree Retention Plan to be submitted as part of a proposed site
development (RMC 4.8.120).
In summary:
Tree Density Calculations
Total number of onsite trees 31
Total number of exempt trees 18
Total number of viable trees 13
Required number of retained trees (.1 X13) 1.3
Number of required replacement trees (1.3 X 12") 16"
Number of 2" caliper replacement trees (16"/2") 8
I have included a detailed report of my findings, if you have any questions please contact me. I can be
reached on my cell phone: 425.890.3808 or by email: sprince202@aol.com.
Warm regards,
