Site Description
The subject site contains and/or is adjacent to a slope that qualifies as an Erosion Hazard Area
as defined in ECDC Chapter 23.80. The subject site slopes downwards generally from east to
west at an approximate 20% slope according to City LiDAR data. Soils on the site are identified
as Alderwood gravelly sandy loam (15% - 25% slope). As a result, the portions of the site with
slopes in excess of 15% slope are considered to be potential erosion 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 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.
