Q Erosion Hazard Areas
Q Landslide Hazard Areas
During review and inspection of the subject site, it was found that the site may contain or be
adjacent to critical areas, including Geologically Hazardous Areas (Erosion Hazard Area and
Landslide Hazard Area), pursuant to Chapters 23.40 and 23.80 of the Edmonds Community
Development Code (ECDC).
The associated LiDAR map indicates that the majority of the site is fairly level with a gentle east -
west declining slope. Near the western edge of the parcel, however, there is a 10 —12 foot tall
cut rockery/retaining wall with a grade of approximately 100%. This was likely installed during
development of the Woodbury at Edmonds plat to make level building lots for the parcels west
of the subject site. Soils throughout the subject site are identified as Alderwood Urban land
complex (8% - 15% slope). As a result, the slopes in excess of 15% are classified as a potential
erosion hazards and the western slope that exceeds 40% is a potential landslide hazard area.
Determination: Study Required
This review applies to the entire subject parcel. When you have a specific development
proposal for this site, contact the Planning Division at 425.771.0220 to determine whether a
critical area report is required for the project.

Landslide Hazard Areas
There is a 50 foot standard buffer (plus 15 foot setback) from the edge of potential landslide
hazard area per ECDC 23.80.070 and ECDC 23.40.280. However, the buffer and setback may be
reduced or eliminated with the submission and City approval of a geotechnical report produced
by a licensed geotechnical engineer. Specific report requirements for landslide hazard areas
and design criteria are found in ECDC 23.80.050 through 23.80.070.
Erosion H,azard Areas
Development is regulated within Erosion Hazard Areas and must meet specific criteria. For
erosion hazard areas with suitable slope stability, an erosion and sediment control plan
prepared in compliance ECDC 18.30 will be considered to meet the critical areas "Study
Required" determination. The determination of "suitable slope stability' will be made by both
the Planning and Engineering divisions of the City of Edmonds. In areas where the slope
stability is not suitable, projects within Erosion Hazard Areas will require a report by a licensed
geotechnical engineer or similar qualified professional. Report requirements and development
standards for alterations within erosion hazard areas are found in ECDC 23.80.050 through
23.80.070.
General Report Requirements
Critical areas reports identify, classify and delineate areas on or adjacent to the subject
property that may qualify as critical areas. They also assess these areas and identify any
potential impacts resulting from specific development proposals. If a specific development
proposal results in an alteration to a critical area, the critical areas report must contain a
mitigation plan. General mitigation requirements for all critical areas are described in ECDC
23.40.110 through 23.40.140.
Critical area reports are most commonly submitted when applying for a building permit or land
use development application but they can be submitted at any time. The minimum
requirements for all critical area reports are listed in ECDC 23.40.090.D. There are additional
report requirements for specific types of critical areas (see below). Note that it is important for
the report to be prepared by a qualified professional as defined in the ordinance.

Allowed Activities & Exempt Proposals
Certain activities are allowed in or near critical area buffers as specified in ECDC 23.40.220.
Similarly, certain development proposals may be exempt from Critical Areas requirements
(ECDC 23.40.230). However, it is much more likely that an alteration to a critical area or buffer
will require some form of City oversight and approval. According to ECDC 23.40.320:
"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, 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.
Unpermitted alteration of a critical area (such as tree cutting or dumping yard waste) can
lead to enforcement action and fines. if you are uncertain about whether an action qualifies
as an allowed or exempt activity, please contact the Planning Division.
Building Setbacks
Unless otherwise provided, buildings and other structures must be set back a distance of 15
feet from the edges of all critical area buffers or from the edges of all critical areas, if no buffers
are required. The following may be allowed in the building setback area: 1) landscaping; 2)
uncovered decks; 3) building overhangs, if such overhangs do not extend more than 30 inches
into the setback area; and 4) impervious ground surfaces, such as driveways and patios;
provided, that such improvements may be subject to water quality regulations as adopted in
the current editions of the International Residential Code and International Building Code, as
adopted in ECDC Title 19.
