CRITICAL AREAS DETERMINATION:STUDY REQUIRED (CRA-2008-0097)
During review and inspection of the subject site, it was found that the site may contain (or be adjacent to) critical
Geologically Hazardous Area (Erosion Hazard Area)
areas, including a , pursuant to Chapter 23.40 of the
Edmonds Community Development Code (ECDC).
The City’s LiDAR map indicates that there is a moderate slope (approximately 25%) along the western edge of the
th
property adjacent to the street (88 Avenue West). The rest of the property is relatively flat or rolling.
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 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.

STUDY REQUIREMENT – EROSION HAZARD AREA
It appears that this property contains or is adjacent to an Erosion Hazard Area.
Erosion Hazard areas include Alderwood and Everett series soils on slopes of 15 percent or greater, among
others.
Landslide Hazard Areas are further defined in ECDC 23.80.020.A.
In addition to the general requirements for Critical Areas reports referenced above, specific Critical Area report
requirements for Erosion Hazard Areas (which are one of the Geologically Hazardous Areas) are provided in
ECDC 23.80.050.
Note that Stable Erosion Hazard Areas may have limited report requirements at the director’s discretion. At a
minimum an erosion and sediment control plan prepared in compliance with the requirements in ECDC
Chapter 18.30 shall be required.
DEVELOPMENT PROPOSALS ASSOCIATED WITH EROSION HAZARD AREAS
Development is restricted within an Erosion Hazard Area and must meet additional 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 other qualified professional.
Note that it is important for the report to be prepared by a qualified professional as defined in the ordinance.
Report requirements are given in ECDC 23.80.050, and more generally in ECDC 23.40.090.D
Development standards are given in ECDC 23.80.060 and 23.80.070.
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.
