RE: Tree Inventory - 3001 NE 16th St. Renton, WA.
Stephanie:
This report is provided to address the recent inventory I conducted of the trees on the
property and just off-site with drip lines that spread onto the property at the address of
3001 NE 16th St. in the City of Renton. WA. Please see the accompanying Tree
Inventory Map for the surveyed locations of the inventoried trees.
1.0 Professional Experience and Credentials
Following is a summarization of my experience and credentials as a consulting arborist:
• Master of Science in Urban Horticulture from Center for Urban Horticulture,
University of Washington, 1996. Focus of study and thesis was nursery
production of Pacific madrone (Arbutus menziesii) and establishment into a
natrual/urban ecosystem.
• ISA Certified Arborist since 1996.
• Tree Risk Assessment Qualified since 2012.
• Consulting arborist, 1996-present.
• Wetland Biologist, 1996-1998
• Other related experience: City of Everett Urban Forestry, summers 1989-1992;
Natural Resource Management staff and Bellevue Botanical Garden staff, City of
Bellevue, 1996-1997.
2.0 Site Conditions and Proposed Development
The property is located in a single-family residence neighborhood and is developed with
a single family residence. Proposed development of the property is to remove the
existing building and redevelop the lot with residences.
3.0 Tree Inventory - Methods and Results
I conducted visual evaluations of all the trees according to ISA standards and based
upon many years conducting such evaluations on trees in the Pacific Northwest. I
oberserved trees up close to inspect conditions of the trunk and from afar to inspect
conditions in the crowns. All assessments were conducted according to the methods
specified in the ISA Tree Risk Assessment Manual and on nearly 22 years experience
conducting such evaluations.
The investigations involved the gathering of the following information:
• Tree species
• Trunk diameter
• Crown spread diameter
• Location factors
• Health and condition notes (general level of vigor, defects, disease or
pest problems)
The City of Renton tree regulations for trees on private properties are specified in RMC
4-1-130 and are used to determine tree retention.
There are 9 trees on the property, and two just off-site within the right-of-way with drip
lines that extend onto the property. The column CSD is crown spread diameter. The
exact location of the trees is not known without a survey. The accompanying tree
evaluation spreadsheet provides information on all of the trees. In general, none of the
trees possess significant defects. The lombardy poplars are advanced in age and have
a moderate amount of branch dieback.
3.0 Tree Retention and Protecton Required
The City of Renton’s tree retention requirements are specified in RMC 4-1-140 and are
as follows:
Single family residences - 2 trees per every 5,000 s.f.
Multi-family residences - 4 trees per every 5,000 s.f.
The property is just below 16,000 s.f. requiring the retention of 6 trees. The locations of
trees 4-10 make them the best candidates for retention.
4.0 Use of This Report and Limitations
This report is provided to address the City of Renton’s requirements for tree inventories
for developing lots. This report addresses only trees on this property and just off-site.
There is no gurarantee that retained trees will survive through construction, and as trees
are dynamic and their conditions can change rapidly due to environmental changes,
Shoffner Consulting cannot be held liable for the failure of any retained trees.
Cordially,
Tony Shoffner
