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 Geologically Hazardous Areas, pursuant to Chapters 23.40 and 23.80 of the
Edmonds Community Development Code (ECDC).
The subject property is located on a cul-de-sac on Edmonds Street Just west of 8'h Avenue North. The
terrain surrounding the subject property and the property itself generally slopes to the west. According to
the City's LiDAR data, the slope drops off at approximately 30%. Soils on the property are identified as the
Alder -Everett gravel sandy loams, which together with the slope classifies the site as a potential erosion
hazard.
This review applies to the entire subject parcel. Depending on the location and type of project proposed
relative to the identified critical areas, certain studies and reports may be required.
ALLOWED ACTIVITIES AND EXEMPT DEVELOPMENT 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). 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 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 — EROSION HAZARD AREA
It appears that this property contains or is adjacent to an Erosion Hazard Area. Erosion Hazard Areas
include:
Those areas with Alderwood and Everett series soils on slopes of 15 percent or greater.
• Any area with slopes of 15 percent or greater and impermeable soils interbedded with granular soils
and springs or ground water seepage.
• Areas with significant visible evidence of ground water seepage, and which also include existing
landslide deposits regardless of slope.
DEVELOPMENT PROPOSALS ASSOCIATED WITH EROSION HAZARD AREAS
Development within an Erosion Hazard Area must meet additional criteria.
❑ For erosion hazard areas with suitable slope stability, the only critical area study needed is an
erosion and sediment control plan prepared in compliance with the requirements set forth in Chapter
18.30 ECDC as part of the construction documents. This option is at the director's discretion, per
Edmonds Community Development Code section 20.80.050.G.
❑ 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.
