The critical area determination for your property is "CRITICAL AREA PRESENT." Note that this determination is a site -specific determination and not a project -specific determination. If the critical area determination is "CRITICAL AREA PRESENT," additional critical areas information or critical areas specific studies may be required for development or alteration of your property depending on the location of the activity. "WAIVER" means no further critical area review is required for development or alteration of your property. If you have any questions regarding this critical area determination, please contact the planner on duty at 425.771.0220.

Critical areas are ecologically sensitive or hazardous areas that are protected in order to maintain their functions and values. Site Location 68XX 161ST PL SW Tax Account Number 00769600000700 Property Owner OLITT RAYMOND Applicant JOSEPH ROWETT 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 an approximate 18,295 square foot lot, which contains and is adjacent to potential severe erosion hazard areas and potential landslide hazard areas. The soils are classified as Alderwood-Everett Gravelly sandy loam, 25-70% slopes according to Snohomish County soils data. LiDAR data indicates that the northeast corner of the lot is relatively flat. LiDAR data also indicates that the northwest corner of the lot contains slopes of approximately 39%, slopes of approximately 40% on the southwest corner of the property, as well as slopes of approximately 48% adjacent to the property on the west and east sides of the property. Slopes 25%-40% with this soil composition are considered potential Severe Erosion Hazard areas. Slopes greater than 40% are considered potential Landslide Hazard Areas. During inspection of the subject site, a large rockery over 20' in height was observed adjacent to the site on the north side of the incoming access easement. Once on the site, the northeast corner of the site was fairly flat. Precipitous slopes were observed on the northwest, west, south, and southeast corners of the property and beyond. This heavily wooded area sloped downward from east to west toward North Meadowdale Road. Any land disturbing activity within 50 feet of the mapped 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. 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.
