SW and 102nd PL. W and is currently developed with a single-family home. The site is relatively level along the southern property boundary, dropping off precipitously to the northwest of the existing residence. According to the Soil Survey of Snohomish County, soils on the subject site consist of "Alderwood Everett Gravelly sandy loams 25-70% slopes" and "Alderwood urban land complex, 2-8% slopes". According to the City LiDAR data, portions of the site contain slopes greater than 40% and thus are classified as a potential landslide hazard, and portions of the site with slopes greater than 15% are considered a potential erosion hazard. Any land disturbing activity within 50 feet of the steep slopes 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.
