Site Location 839 ELM WAY Tax Account Number 27032500300200 Property Owner WALTER L & JANICE E GEAR Applicant WALTER GEAR Critical Area(s) Present ❑ Wetlands (ECDC 23.50): NA ❑ Frequently Flooded Areas (ECDC 23.70): NA ❑ Geologically Hazardous Areas (ECDC 23.80) ❑ Erosion Hazard Areas: Yes ❑ Landslide Hazard Areas: Yes ❑ Seismic Hazard Areas: NA ❑ Fish & Wildlife Habitat Conservation Areas (ECDC 23.90) ❑ Mapped Fish & Wildlife Habitat: NA ❑ Streams: NA Site Description The subject property is located on the north side of Elm Way and is currently developed with a single- family home. According to the Soil Survey of Snohomish County, soils on the subject site consist of "Alderwood Urban land complex, 8-15% slopes" along a majority of the parcel, and the northwest corner of the parcel is "Alderwood Urban land complex, 2-8% slopes." The portion of the property directly off Elm Way is relatively level and then begins to slope down in a northwestern direction along the rear portion of the existing residence. Per the City's LiDAR data, the slope along the northwestern portion of the property is greater than 40%. Additionally, there is a slope greater than 40% on the eastern property which is within 50 feet of the subject parcel. Per ECDC 23.80.020.B.4 any slope 40 percent or greater that exceeds a vertical height of 10 feet, shall be considered a potential landslide hazard. Any land disturbing activity within 50 feet of the steep slope will require a geotechnical report per requirements of ECDC 23.80, with ECDC 23.80.060 and ECDC 23.80.070 specifically addressed in the report. Additionally, per the City LiDAR data, portions of the site contain slopes greater than a 15% slope. 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. 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.
