Critical areas are ecologically sensitive or hazardous areas that are protected in order to maintain their functions and values. Site Location 720 WALNUT ST Tax Account Number 00434209200700 Property Owner DANIEL R\ ELAINE SONNTAG JOHNSON Applicant KEVIN HUBER 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: NA ❑ Seismic Hazard Areas: NA ❑ Fish & Wildlife Habitat Conservation Areas (ECDC 23.90) ❑ Mapped Fish & Wildlife Habitat: NA ❑ Streams: Yes Site DescriDtion The subject property is an approximate 8,276 square -foot lot which contains potential erosion hazard areas and is adjacent to a potential stream. The soils are classified as Alderwood Urban Land complex, 8- 15% slopes, according to Snohomish County soils data. According to LiDAR data, an approximate 16% slope traverses the entire property. Slopes of 15-40% with this soil type are considered erosion hazard areas. According to the City's GIS information, a waterway is located approximately 185 feet northeast of the subject property across Walnut Street. During inspection of the subject site, it was confirmed that the parcel is developed and steadily slopes downward from east to west. A potential stream was identified across the street and east of the property at 741 Walnut Street. 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. The property is outside any potential standard stream buffer widths per ECDC 23.90.040(D)(1) and will not require any additional environmental studies. 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.
