We are writing regarding Earth Subsidence and Landslide Covenant for the Angle Residence project located at 15724
72Id Avenue, Westin Edmonds, Washington. The purpose of our letter is to declare that we have reviewed the
geotechnical engineer's reports and understand their recommendations. We have communicated by writing the risks of
loss to the building owners due to potential landslides on the site. We have incorporated all recommendations from the
geotechnical engineer's report, and per their recommendations, we have designed a slope stabilization and structural
support wall to reduce the potential risk of injury and property damage to the structure by landslide. Specifically, we
have designed a cantilever soldier piles wall under the west end of the building foundation designed to support the
building footings at this location, and to stabilize the slope in accordance with the geotechnical recommendations. The
structure was designed in accordance with the requirements of the 2018 International Building Code, with Washington
State, and local amendments, and is within the standard of care for structures of this type.
Best,
