Site Location 15810 71ST AVE W Tax Account Number 00513300003604 Property Owner N & ALONA & VLADI LITVINCHUK Applicant MARK TREMBACH Critical Area(s) Present ❑ Wetlands (ECDC 23.50): NA ❑ Frequently Flooded Areas (ECDC 23.70): NA Geologically Hazardous Areas (ECDC 23.80) 2 Erosion Hazard Areas: Yes 2 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 vacant property is located to the east of the unopened right-of-way of 72nd Ave West. Soils on the site are identified as Alderwood-Everett Gravelly sandy loams, 25-70% slopes, and Alderwood Urban land complex, 2-8% slopes according to the Snohomish County soils survey. From the north, east, and southern property lines, the site slopes down to the center of the property at slopes of 30-52%. The center of the site is relative level with minimal slopes. The site is also identified as being within the North Edmonds Earth Subsidence and Landslide Hazard Area as defined in Chapter 19.10 ECDC. The steeper portions of slope in excess of 15% are considered an erosion hazard and slopes greater than 40% together with being mapped in the ESLHA qualifies the site as containing potential landslide hazards pursuant to Chapter 23.80 ECDC. 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.
