The critical area determination for your property is "STUDY REQUIRED." 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 17134 TALBOT RD Tax Account Number 27040700104300 Property Owner LISA A TTEE JOHNSTON Applicant LISA JOHNSTON 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 Description The subject property is an approximate 14,810 square foot lot which contains a landslide hazard area. The soils are classified as Alderwood Gravelly sandy loam, 25-70 on the west side of the parcel, and Alderwood Urban land complex, 8-15% slopes on the east side of the parcel according to Snohomish County soils data. LiDAR data indicates that the northwest portion of the lot contains approximate 77% slopes. Slopes greater than 40% are considered Landslide Hazard Areas. There are no mapped slopes on the eastern portion of the parcel. During inspection of the subject site, it was confirmed that the majority of the developed lot is relatively flat. Northwest of the residence contains a very steep slope, sloping downward from east to west toward BNSF rail tracks and the Puget Sound. During the site visit, Planning Division staff identified the presence of a failed rockery -retaining wall on the northwast corner of the property, which presented an approximate 10' drop in elevation from north to south. 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.
