RE: Arborist / Landscape Architect Report
Group Health Renton, Phase II
Dear Cory:
Per the City of Renton’s Site Plan Review Submittal Requirements Checklist, Item #21 Arborist
Report, an evaluation of existing trees describing types, sizes and conditions is to be prepared by a
certified arborist or a licensed landscape architect.
The site was previously cleared for the previous land use. Most of the current condition is open
field with sporadic tree locations. Existing trees were either planted with the previous development, or
are volunteers that have grown since. The majority of the site trees are Cottonwood and Lombardy
Poplars. Both species are short lived, weak wooded and generally inappropriate for the built
environment. Both species have very invasive roots that result in damage to paving surfaces and
underground utilities, and can represent hazards in storm conditions. The entire site will be graded with
approximately 2’ of fill placed in most areas. Tree preservation to meet City of Renton requirements will
occur within project perimeters for the above reasons. All retained trees are considered Priority 3 by City
rating standards due to species type.
Summary:
45 Total Surveyed Trees, based on current Survey
6 Trees within 2’ of site fill area.
30 Trees within 2’ of site fill area and of species not compatible with
developed site.
1 Trees in conflict with Metro Power Easement.
1 Trees in conflict with Public Sidewalk.
38 Total trees to be removed
The table below provides the following information for each tree:
Tree #: as indicated on the Tree Retention / Land Clearing Plan
Tree Species: Common Name
DBH: Trunk diameter in inches 4.5 feet from the ground.
Condition Rating: ‘1’ Removal due to unsuitable species, ‘2’ Removal due to site grading
constraints, ‘3’ Healthy viable tree to remain
