Approval D§IBJE§:TAD 5ORIST REPORT FOR PROPERTY AT APN 313-20-088, located
Signature adj�can �ato 1Vlarfireolfe and 280 eastbound on and off the ramp. The site is currently an
un deve oF&IAA 1Pg tlot with no address.
This arborist report includes the observations and assessment of the four (4) protected
trees growing in planters directly on site. The site was visited on Monday, June 8th,
2023.
Assignment: Review three (3) Pinus halepensis (Aleppo pine) trees located in planters
directly adjacent to the sound wall that separates the neighborhood and the lot and
one (1) Pinus piney (Stone pine) located in a planter island located at APN 313-20-088,
shown in Figure 1.
The assignment requires the following activities: visit the site, verify the tree, list the
tree species, diameter, crown radius, tree condition, impacts to the property, and
mitigation options.
Observations: The site was visited on Monday, June 8th, 2023, at about 11:00 am.
The tools used were a diameter tape and a screwdriver as a probe. The map's four (4)
trees were measured for trunk diameter at approximately 4.5 feet above grade with a
diameter tape. The tree was assessed and rated for health and structure. Overall
condition considering branch structure, decay, leaf quality, vitality, dieback, lean, and
other issues that affect the state of the trees.
The tree's health condition was determined by observing the tree foliage, twig growth,
leaf density decay, insects, diseases, and dead branches. The structure rating was
determined by observing branch attachment, crotch structure, trunk flare, surface roots,
growth habit, and physical damage. The overall condition combines the health and the
structure based on the most significant needs.
The two (2) Pinus halepensis (Figure 2.) fell over in the recent storm. The larger of the
two did not have an adequate root structure to support the tree in the environmental
conditions caused by the winter storms. This led to a stability issue when heavy rain
and wind gusts exceeded 60 mph. The larger of the two trees failed, taking the smaller
tree down with it.
