CRITICAL AREAS RECONNAISSANCE REPORT
Site Location:
7011 174th Street SW
Tax Acct. Number:
00539100000300
Determination:
Study Required
Determination #:
CRA -2010-0079
Applicant Rep:
Cozy Homes Corp.
Owner/Applicant:
Robert Rixmann
BACKGROUND
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 parcel is fairly level on the southeastern one-third of the parcel then slopes down
gradually toward the northwest. According to the City's LIDAR data, the steepness of the slope
varies from approximately 15% to 35% which qualifies the slope as an erosion hazard.
This study 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.
DEVELOPMENT PROPOSALS ASSOCIATED WITH EROSION HAZARD AREAS
Development within an Erosion Hazard Area must meet certain criteria.
• For projects within erosion hazard areas with suitable slope stability, the only
critical area report needed is an erosion and sediment control plan prepared in
compliance with the requirements set forth in Chapter 18.30 ECDC. This option is at
the director's discretion, per ECDC 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
Edmonds Community Development Code.
• Report requirements are specified in ECDC 23.80.050, and more generally in ECDC
23,40.090.D.
• Development standards are identified in ECDC 23.80.060 and 23.80.070.
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 must also contain a mitigation
plan.
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. Please 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.
If you have any questions about this determination, please contact a Planner for more information.
