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. Regards, ROSE HAAS Planning Division Development Services Department Enc: Critical Area Determination portion of the site extending into Lake Ballinger, and a small corner of "Mukilteo Muck" on the Southeastern portion of the lot, extending into the lake. Soil types are recorded per the Snohomish County soils survey. According to the City's LiDAR information, the eastern portion of the parcel extends into the associated wetland associated with Lake Ballinger approximately 117ft. Within the lake portion of the lot, LiDAR data also shows a protected species area - mapped as "Waterfowl Concentrations." Additionally, Flood Plain A extends past the wetland approximately 175 feet inland, and approximately 58 feet from the single-family home. A site visit confirmed that the parcel is entirely flat. Also noted is the presence of Lake Ballinger and higher than normal water levels indicating the presence of a flood zone. 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.
