Site Description
During review and inspection of the subject site, it was found that the site contains and/or is
adjacent to critical areas, including Streams and Geologically Hazardous Area (Erosion Hazard).
The majority of the property is level; however, according to the City's LiDAR map there are
potential slopes greater than 15% along the east and west property lines. Soils on the site are
identified as Alderwood Urban land complex, 8-15% slopes. Slopes in excess of 15% grade are
categorized as potential Erosion Hazard Areas. The combination of the underlying soil types and
grade of slope classify the site as a potential Erosion Hazard.
During site inspection, it was confirmed that Shelleberger Creek is present along the
southwestern corner of the property.
What does this mean?
The critical area regulations are only triggered when an alteration is proposed to a critical
area or its buffer. However, once an alteration in or near critical area is proposed, critical
area studies and City review and approval may be required.
What is an 'Alteration'?
According to Section 23.40.005 of the Edmonds Community Development Code (ECDC):
"Alteration" means any human -induced action which
changes the existing conditions of a critical area or its
buffer. Alterations include, but are not limited to:
grading, filling; dredging; draining; channelizing;
cutting, pruning, limbing or topping, clearing,
relocating or removing vegetation; applying herbicides
or pesticides or any hazardous or toxic substance;
discharging pollutants; paving, construction,
application of gravel; modifying for surface water
management purposes; or any other human activity
that changes the existing landforms, vegetation,
hydrology, wildlife or wildlife habitat value of critical
areas.
