Site Descri tion
The subject site contains and/or is adjacent to slopes that qualify as both Erosion Hazard and
Landslide Hazard Areas as defined in ECDC Chapter 23.80. The eastern and central portions of
the site are relatively level; however, the northern portion of the site slopes down to the
adjacent properties to the north and the western portion of the site slopes down to the
adjacent properties to the west. These slopes exceed 40% and, therefore, qualify as both
Erosion Hazard Areas and Landslide Hazard Areas. Soils on the site are identified as Alderwood
urban land complex (8% - 15% slope). As a result, the portions of the site with slopes in excess
of 15% slope are considered to be potential erosion hazards and portions of the site with slopes
in excess of 40% is considered to be potential landslide hazards.
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 a 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.
