Existing Tree Evaluation
Dear Robert:
I reviewed the existing significant trees at the above-referenced site on 9/11/15 to
determine species, diameter at breast height (dbh) and overall health of each per the City
of Renton’s Municipal Code Section 4-4-130. Following are the significant trees found on
the site along with their species, dbh, drip line (radius), overall health and whether they
are proposed for removal or retention. This information is also depicted on L1 of the
Preliminary Landscape Plan drawing set for the project submittal dated 9/17/15.

TREE CALCULATIONS
Per code, 18 of the 25 significant trees present on this site are required to be included in
the tree calculations for preservation. The other 7 trees are located in right-of-ways and
exempt from the calculations. In the R-8 Zone, 30% are required to be retained, which
equals 5 trees. Only 4 are proposed for retention, therefore tree replacement is required
at a rate of 12 caliper inches per shortfall of significant trees for retention (2). Therefore,
we’ve included a minimum of 12 one inch caliper trees on the Preliminary Landscape Plan
(Sheet L2) to be planted as replacements for the 1 significant tree shortfall on
preservation.
