Site Description
Nearly all of the subject site is located within the mapped North Edmonds Earth Subsidence and
Landslide Hazard Area (ESLHA) or buffer. The steepest portion of the bluff is in the middle of
the site with somewhat more level areas on the west (below the bluff) and east (above the
bluff). According to NRCS soils data, most of the site is underlain by Alderwood-Everett gravely
sandy loams, 25-70% slope but the western edge is underlain by Alderwood Gravelly sandy
loam (15-25-% slope) while the eastern edge is Alderwood Urban land complex (2-8% slope).
Given the soils and slopes on and adjacent to the property and its location within the ESLHA,
the site is considered to be a potential erosion and landslide hazard area.
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.
