Q Streams
Q Geologically Hazardous Areas
Q Erosion Hazard Areas
Q Landslide Hazard Areas (ESHLA)
During review and inspection of the subject site, it was found that the site may contain or be
adjacent to critical areas, including a possible Stream and Geologically Hazardous Areas
(Erosion Hazard Area or Landslide Hazard Area), pursuant to Chapters 23.40, 23.80 and 23.90 of
the Edmonds Community Development Code (ECDC).
The subject parcel is located within the mapped North Edmonds Earth Subsidence and
Landslide Hazard Area (ESHLA). The associated LiDAR map indicates that the parcel slopes
gradually downward from east to west at a grade of between 15% and 20%. Soils throughout
the site are identified as Alderwood Gravelly sandy loams (15% - 25% slope). As a result, the
slopes in excess of 15% are classified as a potential erosion hazards.
A narrow water feature runs east -west across the parcel to the north, approximately 25 feet
from the northern parcel boundary of the subject site. It is unknown whether this is regulated
stream; a report from a qualified biologist would be required to make that determination.
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.

Streams
Streams are areas where surface waters produce a defined channel or bed which demonstrates
clear evidence of the passage of water. Regulated as types of Fish and Wildlife Habitat
Conservation Areas, streams are classified according to whether they run year round and
whether they support fish populations according to the classification system listed in ECDC
23.90.010.A.1.
Development proposals that encroach into streams or their buffers may be allowed through the
approval of a critical area report. In addition to the general requirements for critical areas
reports, specific report requirements for Fish and Wildlife Habitat Conservation Areas are
provided in ECDC 23.90.020.A to C with additional requirements for streams in ECDC
23.90.020.D.
The minimum buffer widths for streams vary depending on the type of stream and are listed in
ECDC 23.90.040.D.1. The width of a stream buffer may be reduced through buffer
enhancement if through the review of a Stream Buffer Enhancement Plan that meets the
specific requirements referenced in ECDC 23.90.040.D.2. The maximum amount that a buffer
'be reduced through buffer, enhan ernent is 50%., A buffer may also be modified through
buffer averaging. The criteria applied to buffer averaging are listed in ECDC 23.90.040.D.2. The
maximum amount that the buffer width can be reduced at any single location through buffer
averaging is 50%. Development proposals that propose encroachments into buffers beyond
what is allowed through the above methods require a Critical Areas Variance in accordance
with ECDC 23.40.210.
Erosion Hazard 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
Page 12
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.
Landslide Hazard Areas
Development is restricted but not prohibited within Landslide Hazard Areas and their
associated buffers. There are standard required buffers and setbacks from landslide hazard
areas (per ECDC 23.80.070 and ECDC 23.40.280); however, these buffers and setbacks 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.
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 Arca reports are p ost o, manly ubmitted hen applying fora building permit or'l
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:
Page 13
"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.
