Critical areas are ecologically sensitive or hazardous areas that are protected in order to maintain their functions and values. Site Location 1131 Sea Vista Place (also known as 1131 9TH AVE S) Tax Account Number 00568300000200 Property Owner KONO PHILIP J & LIANNE L U TRUST Applicant KONO PHILIP J & LIANNE L U TRUST Critical Area 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: NA Site Description West of the existing house is a small slope that falls off toward Sea Vista Place with a grade of approximately 30% (12' height over 40' run). Since the underlying soils are Alderwood Urban land complex series (8-15% slope), the slope is considered to be a potential erosion hazard area. 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.
