According to the Soil Survey of Snohomish County, soils on the subject site consist of "Everett gravelly sand loam, 0-8% slopes" and "Everett gravelly sand loam, 15-25% slopes." The site is relatively level along the eastern portion and in the vicinity of the existing home. The entire site slopes down to the west and north-west at slopes of 25-32%, according to City LiDAR data. The combination of the underlying soil types and the grade of the slopes classifies the site as a Severe Erosion Hazard Area. An Erosion and Sediment control plan compliant with Chapter 18.30 ECDC may be required for development on a site containing erosion hazard areas with slopes greater than 25%. 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.
