Subject: Critical Areas Determination (CRA2024-0061)
Site Address: 731 HANNA PARK RD
Dear Applicant/Owner,
Please find the enclosed critical area determination for the Critical Areas Checklist you submitted
to the City of Edmonds Planning Division. The critical area determination for your property is
"CRITICAL AREA PRESENT." Note that this determination is a site -specific determination and not
a project -specific determination.
If the critical area determination is "CRITICAL AREA PRESENT," additional critical areas
information or critical areas specific studies may be required for development or alteration of
your property depending on the location of the activity. "WAIVER" means no further critical area
review is required for development or alteration of your property.
If you have any questions regarding this critical area determination, please contact the planner
on duty at 425.771.0220.
Regards,

Critical Area Determination (CRA2024-0061)
Based on a review and inspection of the subject site, staff has determined that one or more
critical areas are located on or near the site. Critical areas are ecologically sensitive or
hazardous areas that are protected in order to maintain their functions and values.

Site Descriation
The subject property is located west of the northern terminus of Hanna Park Road and is currently
developed with a single-family residence. According to the Soil Survey of Snohomish County, soils on the
subject site are "Alderwood urban land complex, 2-8% slopes". The subject property is level except at
the western boundary, where it drops precipitously down to the BNSF right-of-way. According to City
LiDAR data the site contains slopes greater than 15% which are considered a potential erosion hazard.
Additionally, the LiDAR data shows slopes greater than 40 percent with a 10-foot change in elevation,
which are considered a potential landslide hazard.
Buffers may extend on the subject site and thus any land disturbing activity within 50 feet of the steep
slope on the neighboring property will require a geotechnical report per requirements of ECDC 23.80,
with specific reference to ECDC 23.80.060 and ECDC 23.80.070. An Erosion and Sediment control plan
compliant with chapter 18.30 ECDC may be required for development on a site containing an erosion
hazard area which may be reviewed as part of a building permit.
Adjacent to the site, across the BNSF right-of-way is a frequently flooded area - floodplain AE. Puget
Sound, as shoreline of the State, is also a Type S stream. Buffers from the stream and potential could
impact the subject site. A qualified professional will need to assess the area to determine whether the
buffer is interrupted by the BNSF right-of-way.
What does this mean?
The critical area regulations are only triggered when an alteration is proposed to a critical area or
its buffer. However, once an alteration in or near critical area is proposed, critical area studies and
City review and approval may be required.
What is an `Alteration'?
According to Section 23.40.005 of the Edmonds Community Development Code (ECDC):
"Alteration" means any human -induced action which changes the existing conditions of a critical area or
its buffer. Alterations include, but are not limited to: grading, filling; dredging; draining; channelizing;
cutting, pruning, limbing or topping, clearing, relocating or removing vegetation; applying herbicides or
pesticides or any hazardous or toxic substance; discharging pollutants; paving, construction, application of
gravel; modifying for surface water management purposes; or any other human activity that changes the
existing landforms, vegetation, hydrology, wildlife or wildlife habitat value of critical areas.
Unpermitted alteration of a critical area or buffer (including tree trimming or topping, dumping yard
waste, or application of pesticides or fertilizers) can lead to enforcement action and fines. Before
undertaking any work, please contact the City to verify whether critical area studies and City review is
necessary.
