Critical areas are ecologically sensitive or hazardous areas that are protected in order to maintain their functions and values. Site Location 9204 Olympic View Dr. Tax Account Number 00565600101502 Property Owner Brad Wall Applicant Kristin Hanson Critical Area(s) Present ❑ Wetlands (ECDC 23.50) ❑ Frequently Flooded Areas (ECDC 23.70) ® Geologically Hazardous Areas (ECDC 23.80) © Erosion Hazard Areas ❑ Landslide Hazard Areas ❑ Seismic Hazard Areas ❑ Fish & Wildlife Habitat Conservation Areas (ECDC 23.90) ❑ Streams Site Description During review and inspection of the subject site, it was found that the site contains critical areas, including Geologically Hazardous Area (Erosion Hazard), pursuant to Chapter 23.80 of the Edmonds Community Development Code (ECDC). The associated LiDAR map indicates that a southwest -facing slope runs across the eastern portion of the subject site. The slope drops approximately 16 -feet over a horizontal distance of 43.6 -feet, a 36.7% grade. Soils on the site are identified as Alderwood gravelly sandy loams, 15- 25%. Slopes in excess of 15% grade are categorized as potential Erosion Hazard Areas. The combination of the underlying soil types and grade of slope classify the site as a potential Severe Erosion Hazard. The site does not contain any known wetlands, fish and wildlife habitat conservation areas, or streams. 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.
