Site Location 8475 FREDERICK PL Tax Account Number 00594400006402 Property Owner RYAN & SYDNEY COCHRAN Applicant HEIDI HELGESON Critical Area(s) Present ❑ Wetlands (ECDC 23.50): NA ❑ Frequently Flooded Areas (ECDC 23.70): ❑ Geologically Hazardous Areas (ECDC 23.80) ❑ Erosion Hazard Areas: ❑ Landslide Hazard Areas: ❑ Seismic Hazard Areas: ❑ Fish & Wildlife Habitat Conservation Areas (ECDC 23.90) ❑ Mapped Fish & Wildlife Habitat: Yes ❑ Streams: Yes Site Description The subject property is a heavily wooded and an approximately 20,038 square foot lot with no slopes and no erosion hazards present. The soils are classified as Alderwood Urban land complex, 8-15% slopes according to Snohomish County soils data. According to the City's LiDAR information, Perrinville Creek is approximately 120 feet from the subject property's boundary to the West. During inspection of the subject site, it was confirmed the presence of Perrinville Creek on the 8500 and 8522 Frederick Place addresses. No other critical areas were observed on or directly adjacent to the site. Streams are considered critical areas pursuant to ECDC Chapter 23.90 and may require development buffer zones of 40ft - 150ft (ECDC 23.90.040(D)). Perrinville Creek network is categorized as Type F by the Washington Department of Natural Resources. Type F streams and waterways contain fish habitat and are considered fish and wildlife habitat conservation areas within the City of Edmonds (ECDC 23.90.010(A)(1)(b)). A qualified professional will need to assess the area to determine the classifications of the potential stream and its associated fish and aquatic habitats. 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.
