<br /> (35'or greater). By these criteria, all 12 trees assessed on the 4108 Foothill Rd. property are
<br /> considered Heritage.

<br />tween the driplines. All of the trees were mature in form and development.
<br /> Ten (10) of the trees were valley oaks. Trunk diameters ranged from 24"to 43", with 4 trees
<br /> below 30" in diameter and 6 above. Seven (7) of the valley oaks were in good or excellent
<br /> condition (Photo 1, following page) and 3 were in fair. Most showed minor dieback of twigs and
<br /> branches and had slightly thin crowns. Valley oaks#21 and 27 had more significant defects,
<br /> including trunk wounds and internal decay.
<br /> Two (2) coast live oaks were assessed. Coast live oak#19 was mature at 37" in trunk diameter
<br /> and in good condition. Coast live oak#20 was over-mature at 56" and in poor condition. The
<br /> poor condition of coast live oak#20 was the result of extensive trunk wounds and internal decay
<br /> (Photo 2, following page).

<br /> Trees with good health and structural stability that have the potential
<br /> for longevity at the site.
<br /> Moderate: Trees with somewhat declining health and/or structural defects than
<br /> can be abated with treatment. The tree will require more intense
<br /> management and monitoring, and may have shorter life span than
<br /> those in 'high' category.
<br /> Low: Trees in poor health or with significant structural defects that cannot
<br /> be mitigated. Tree is expected to continue to decline, regardless of
<br /> treatment. The species or individual tree may have characteristics
<br /> that are undesirable for landscapes, and generally are unsuited for
<br /> use areas.
