CRITICAL AREAS RECONNAISSANCE REPORT
Site Location:Tax Acct. Number:
102 Main St. 00454800300700
Determination:Determination #:
Study Required CRA-2008-0076
Applicant:Owner:
David A. Bresee Splash Properties IV LLC
CRITICAL AREAS RECONNAISSANCE REPORT:STUDY REQUIRED
During review and inspection of the subject site, it was found that the site contains and/or is adjacent to
critical areas, including a Seismic Hazard Area, pursuant to Chapters 23.40 and 23.80 of the Edmonds
Community Development Code (ECDC).
GENERAL CRITICAL AREAS REPORT REQUIREMENTS
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 to submit
the entire study with your specific development application.
Please review the minimum report requirements for all types of Critical Areas that 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 there is 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.
STUDY REQUIREMENT – SEISMIC HAZARD AREA
It appears that this property contains and/or is adjacent to a Seismic Hazard Area. Seismic hazard areas
are areas subject to severe risk of damage as a result of earthquake-induced ground shaking, slope
failure, settlement, soil liquefaction, lateral spreading, or surface faulting. Settlement and soil liquefaction
conditions occur in areas underlain by cohesionless, loose, or soft-saturated soils of low density, typically
in association with a shallow ground water table.
DEVELOPMENT PROPOSALS ASSOCIATED WITH SEISMIC HAZARD AREAS
Development within a Seismic Hazard Area must meet additional criteria.
A report by a licensed Geotechnical Engineer is required for applicable projects within Seismic
Hazard Areas. Note that it is important for the report to be prepared by a qualified professional as
defined in the ordinance.
Geotechnical reports within Seismic Hazard Areas must address liquefaction.
Report requirements are provided in ECDC 23.80.050 and more generally in ECDC 23.40.090.D.

Activities proposed to be located in seismic hazard areas shall meet the development standards
of ECDC 23.80.060.
ALLOWED ACTIVITIES
Certain activities are allowed in or near critical area buffers as specified in ECDC 23.40.20. If you have
any questions about whether your proposed development qualifies as an allowed activity, please contact
a Planner for more information.
EXEMPT DEVELOPMENT PROPOSALS
Certain development proposals may be exempt from Critical Areas Requirements (ECDC 23.40.230). If
you think that a specific development proposal may be exempt, contact a Planner for more information.
