Subject: Letter of Understanding Geological Risk – VIOC Renton
To Whom It May Concern
This letter serves to formally acknowledge our understanding and acceptance of the inherent risks
associated with developing the property located at NE 4th Street & Whitman Court NE within an area
identified as having unstable geologic conditions.
As cited in our Geotechnical Report dated July 18, 2025, and consistent with the Geologic Map of
Washington reviewed by the preparers of the report, the site is situated in an area characterized by
Pleistocene till and outwash. These deposits are composed of a varied mix of clay, silt, sand, gravel,
cobbles, and boulders, all originating from or deposited by continental glaciers. We further understand that,
locally, the area may also include organic material such as peat, nonglacial sediment, modified land, and
artificial fill, as specifically indicated in our aforementioned Geotechnical Report. Additionally, groundwater
observations indicated perched zones that can significantly affect water table depth measurements and
subsequently our foundation design that will be considered.
We fully comprehend the potential implications of these geological characteristics for the stability of the
site and any proposed structures and will design our proposed project accordingly. Furthermore, we
commit to advising, in writing, any prospective purchasers of the site, or any prospective purchasers of
structures or portions of structures on the site, of the unstable potential of this area.
This disclosure will be made clear and prominent in all relevant sales and transfer documentation to ensure
future owners are fully informed of these conditions.
Sincerely,
Laura Whitt Orr
