Arborist Report
LOCATION OF PROPERTIES
There are two separate parcels near the NW 1/4 of the SW 1/4 of Sec=on 29 within T23N, R5E,
City of Renton, County of King, State of Washington:
Property 1 - 3303 Main Avenue South is an exis=ng single family home built 34 years ago in
1988. Along its northern property line is a natural area designated as Common Property and
Tract B (PID 948576 TR-B) from the King County Recorders Office records.
Property 2 - Parcel Iden=fica=on Number 948576 TR-B, Common Area Type 2. It is an area just
over an acre in size. It is heavily wooded containing mostly black coaonwood and bigleaf maple
with an understory of Himalayan blackberry. Both trees were found on Tract B.
TREES
Tree 1: It is likely that this tree was damaged during construc=on of the subdivision prior to
1988. A large canker has infected the southern one-third of the trunk up the stem for more than
24 feet. A co-dominant stem (trunk) has long decayed, contains two obvious conks and disease
has most likely spread into the live trunk. The main leader at the top has been dead for several
years. There are live branches that are becoming larger each year with many adjacent to dead
or decaying wood.
Tree 2: This black coaonwood appears to be in very good to excellent health and condi=on. It
has 4 rela=vely small, live branches that hang over the roof at 3303 Main Avenue South.
Damage to the roof has occurred recently (see homeowner photo).
Tree Summary Table

house. 90%
OBSERVATIONS AND RECOMMENDATIONS
Tree 1 (Tract B): This tree is in poor condi=on and not expected to improve with =me but
con=nue to decline. Most likely construc=on damage to the tree occurred when building and
grading were performed nearby many years ago. Two feet of soil around the trunk was
observed and a large canker up the trunk are indicators of this kind of damage were common
when wooded property was developed.
The main trunk at the top of the tree died back more than 20 feet down, another indicator of
tree decline. Two basal conks were noted decaying a co-dominant stem or trunk that had
deteriorated. More than likely disease and decay are spreading into the remaining trunk.
The ra=ng out of 100% indicates an excellent condi=on of a tree and a ra=ng of 0% a dead tree.
While this maple tree is not dead neither is it in excellent condi=on a ra=ng of 40% is assigned
and the tree poses an immediate risk of failure to people and property at any=me.
The recommenda=on to remove is assigned to this tree.
Tree 2 (Tract B): Because of its very
good condi=on a ra=ng of 90% or
higher is assigned to the
coaonwood. Some minor branch
pruning will eliminate damage to
roof shingles from branches
striking and rubbing.
The recommenda=on is to prune
branches back to the main trunk
for those overhanging the roof. Do
not allow the use of climbing spurs
to access tree.
