.,,,.)ite Descript
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 or Landslide Hazard Area), pursuant to Chapter
23.40 of the Edmonds Community Development Code (ECDC). Geologically hazardous areas include areas
susceptible to erosion, land sliding, earthquake, or other geological events. They pose a threat to the health and
safety of citizens when incompatible development is sited in areas of significant hazard. Such incompatible
development may not only place itself at risk, but also may increase the hazard to surrounding development and
use. Cited sections of the Edmonds Community Development Code (ECDC) can be found on the City of Edmonds
website at www.edrrAcands)/va.gov.
The subject property has an existing residence that sits on a relatively level portion of the property. On the west
side of the residence the property drops almost vertically down to the rail road tracks and Puget Sound. Due to
the steepness of the slopes on the property; the site has been identified as a potential landslide hazard area.
Projects proposed further than 65' from the top or toe of the slope (50' buffer + 15' setback from the critical area)
may not require a geotechnical report to address critical areas issues (of course, other departments may require a
report to address their codes). Projects within 65' of the top of the slope will require a geotechnical report
consistent with the requirements identified below.
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). If you have any
questions about whether your proposed development qualifies as an allowed or exempt activity, please contact
a Planner for more information.
General Report Re(lUirenients
Critical Areas Reports identify, classify. and delineate any 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 your specific
development proposal. If a specific development proposal results in an alteration to a critical area the critical
areas report will also contain a mitigation plan. You have the option of completing the portion of the study that
classifies and delineates the critical areas and waiting until you have a specific development proposal to complete
the study. You may also choose submit the entire study with your specific development application. Please review
the minimum report requirements for all types of Critical Areas which are listed in ECDC 23.40.090.D. There are
additional report requirements for different 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. There are options on how to
complete a critical areas study and an approved list of consultants that you may choose from. You may contact the
Planning Division for more information. General Mitigation Requirements for all Critical Areas are discussed in
ECDC 23.40.110 through 23.40.140.
Development is restricted within a Landslide Hazard Area and its buffer. Projects that will intrude into these areas
will require a report by a licensed Geotechnical Engineer. Geologically hazardous areas include areas susceptible
to erosion, land sliding, earthquake, or other geological events. They pose a threat to the health and safety of
citizens when incompatible development is sited in areas of significant hazard. Such incompatible development
may not only place itself at risk, but also may increase the hazard to surrounding development and use.
The criteria that are applied depend on the amount that the buffer is reduced. The buffer can be reduced to a
minimum of ten (10) feet (with an additional 15' building setback per ECDC 23.40.280) if a report is prepared that
meets the standards listed in ECDC 23.80.050). The alteration must also meet the requirements listed ECDC
23.80.060. In addition, proposals to reduce the buffer to less than ten (10) feet must comply with the design
standards listed in ECDC 23.80.070.A.3. Development is restricted within a Landslide Hazard Area and its buffer.
Projects that will intrude into these areas will require a report by a licensed Geotechnical Engineer.
This review applies to the entire subject parcel. Depending on the location and project proposed relative to the
identified critical areas, certain studies and reports may be required. Please contact the Planning Division at
425.771.0220 if and when you have a specific development proposal for this site in order to discuss the various
permits that will be required. Please note that tree removal on sites containing critical areas may first require a
tree cutting permit, and the illegal removal of trees may result in penalties and steep fines (ECDC 18.45.070,
ordinance #3828). „11",e
