The critical area determination for your property is "APPLIED." 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 109 OLYMPIC AVE Tax Account Number 00434204002101 Property Owner JOHN F SCHEUERMAN Applicant MEGHANN MINGLE Critical Area(s) Present 2 Wetlands (ECDC 23.50): Yes ❑ Frequently Flooded Areas (ECDC 23.70): NA 2 Geologically Hazardous Areas (ECDC 23.80) 2 Erosion Hazard Areas: Yes 2 Landslide Hazard Areas: Yes ❑ Seismic Hazard Areas: NA 2 Fish & Wildlife Habitat Conservation Areas (ECDC 23.90) 2 Mapped Fish & Wildlife Habitat: Yes ❑ Streams: NA Site Description During review and inspection of the subject site, it was found that the site contains and/or is adjacent to multiple critical areas, including severe erosion hazard areas, landslide hazard areas, mapped sensitive habitats and species area, and a mapped wetland. Soils on the site are identified as Alderwood-Everett gravelly sandy loams, 25-70 and Alderwood Urban Land complex, 8-15% slopes, according to the Snohomish County soil survey. Alderwood-Everett gravelly sandy loams, 25-70 comprise the majority of the property, with Alderwood Urban Land complex, 8-15% slopes comprising the northeast corner of the property. The subject property is developed with an existing single-family residence with an attached garage. There is an existing rockery along the property line to the north. The residence is located on a portion of the property that is relatively flat and has been leveled, though the property slopes moderately down to the south on either side of the residence. There are steep slopes in excess of 40% immediately adjacent to the north. These slopes, together with the soils classify the site as containing potential landslide and erosion hazards pursuant to ECDC 23.80. Buffers may extend on the subject site and thus any land disturbing activity within 50 feet of the landslide hazard 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 may be reviewed as part of a building permit. According to the City's LiDAR data, there is a potential wetland to the southeast of the subject site. The wetland was not observed during the reconnaissance. The wetland, as well as its, associated buffers, could also impact the subject site. City LiDAR data also indicates that the subject site is within Sensitive Habitats and Species protection area and development on the property may require further study pursuant to ECDC 23.90. 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.
