Site Location 17521 72ND AVE W Tax Account Number 00513100014303 Property Owner BRETT T & DIANA L BELL Applicant RR FOUNDATION 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 DescriDtion The subject property is located on the east side of 72nd Avenue West. The property sits in a bowl with the terrain sloping in from 72nd Avenue west and surrounding properties to the south and east. Soils on the property are classified as Alderwood urban land complex, 2-8% slopes according to the Snohomish County soils survey. Slopes along the southern and northeastern property lines slope up towards the adjacent property at approximately 43% according to the City LiDAR information. Elsewhere on the property slopes are approximately 21%. The steepness of the slopes together with the soil classification classifies slopes on the site as potential landslide and erosion hazards pursuant to Chapter 23.80 ECDC. Any land disturbing activity within 50 feet of the landslide hazard areas will require a geotechnical report per requirements of ECDC 23.80, with specific reference to ECDC 23.80.060 and ECDC 23.80.070. Additionally, 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 would be reviewed as part of a building permit. 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.
