Cited sections ofthe Edmonds Community Development Code (ECDC) can be found on the City of Edmonds website at . The site slopes down from east (at the street) tothe west. The eastern portion ofthe site (between the street and the western wall of the house) generally has a slope of about 14 percent; west of this area is a steep slope and rockery (appearing toextend onto the property tothe west). |nthis area, the elevation drops from about 294feet at the rear of the house to about 278 at the foot of the rockery, according to City LiDAR data. According tothe US Natural Resources Conservation 8e/vice, soils onthe site are in theA|derwood series, which may experience significant erosion. Due tothe degree ofthe slope and the presence of these soils, the site contains and/or is adjacent to a slope that is considered both an Erosion Hazard Area (over 15 percent slope) and Landslide Hazard Area (over 40percent dope). H U �� " °�� ° �� K �-�UU�� .��8��K�U��«� �� 0�� 0��Us Certain activities are allowed in or near critical area buffers as specified in ECDC 23.40.220. Similarly, certain development proposals may be exempt from Critical Areas requirements (ECDC 23.40.230). (fyou have any questions about whether your proposed development qualifies as an allowed or exempt activity, please contact a Planner for more information. e1[1 E"C i d I' °' , ' '�.; �" e cl, i,� I V°e Ilr�r `'Ir Critical Areas Reports identify, classify and delineate any areas on or adjacent to the subject property that may qualify as critical areas. They also assess these areas and identify any potential impacts resulting from your specific development proposal. If a specific development proposal results in an alteration to a critical area, the critical areas report will also contain a mitigation plan. You have the option of completing the portion of the study that classifies and delineates the critical areas and waiting until you have a specific development proposal to complete the study. You may also choose submit the entire study with your specific development application. Please review the minimum report requirements for all types of Critical Areas which are listed in ECDC 23.40.090.D. There are additional report requirements for different types of critical areas (see below). Note that it is important for the report to be prepared by a qualified professional as defined in the ordinance. There are options on how to complete a critical areas study and an approved list of consultants that you may choose from. You may contact the Planning Division for more information. General Mitigation Requirements for all Critical Areas are discussed in ECDC 23.40.110 through 23.40.140. E�C . �z,,,, �r„i ..,, � UI III �(. � ,°„ �. d� r e 1., J� %7 It appears that this property contains and/or is adjacent to an Erosion Hazard Area. Geologically hazardous areas include areas susceptible to erosion, land sliding, earthquake, or other geological events. They pose a threat to the health and safety of citizens when incompatible development is sited in areas of significant hazard. Such incompatible development may not only place itself at risk, but also may increase the hazard to surrounding development and use. Erosion Hazard areas include Alderwood and Everett series soils on slopes of 15 percent or greater, among others. Landslide Hazard Areas are further defined in ECDC 23.80.020.A. In addition to the general requirements for Critical Areas reports referenced above, specific Critical Area report requirements for Erosion Hazard Areas (which are one of the Geologically Hazardous Areas) are provided in ECDC 23.80.050. Note that Stable Erosion Hazard Areas may have limited report requirements at the director's discretion. At a minimum an erosion and sediment control plan prepared in compliance with the requirements in ECDC Chapter 18.30 shall be required. Development is restricted within an Erosion Hazard Area and must meet additional criteria. For erosion hazard areas with suitable slope stability, an erosion and sediment control plan prepared in compliance with ECDC 18.30 will be considered to meet the Critical Areas "Study Required” determination. The determination of "suitable slope stability" will be made by both the Planning and Engineering divisions of the City of Edmonds. In areas where the slope stability is not suitable, projects within Erosion Hazard Areas will require a report by a licensed Geotechnical Engineer or other qualified professional. Note that it is important for the report to be prepared by a qualified professional as defined in the ordinance. Report requirements are given in ECDC 23.80.050, and more generally in ECDC 23.40.090.D. Development standards are given in ECDC 2.3.80.060 and 23.80.070. >,-q;, I It appears that this property contains and/or is adjacent to a Landslide Hazard Area. Geologically hazardous areas include areas susceptible to erosion, land sliding, earthquake, or other geological events. They pose a threat to the health and safety of citizens when incompatible development is sited in areas of significant hazard. Such incompatible development may not only place itself at risk, but also may increase the hazard to surrounding development and use. Development is restricted within a Landslide Hazard Area and its buffer. Projects that will intrude into these areas will require a report by a licensed Geotechnical Engineer. The criteria that are applied depend on the amount that the buffer is reduced. The buffer can be reduced to a minimum of ten (10) feet (with an additional 15 -foot building setback per ECDC 23.40.280) if a report is prepared that meets the standards listed in ECDC 23.80.050. The alteration must also meet the requirements listed in ECDC 23.80.060. In addition, proposals to reduce the buffer to less than ten (10) feet must comply with the design standards listed in ECDC 23.80.070.A.3. )) �", .�� ° N °yaw � : ��F r I c i u This review applies to the entire subject parcel. Depending on the location and project proposed relative to the identified critical areas, certain studies and reports may be required. Please contact the Planning Division at 425.771.0220 if and when you have a specific development proposal for this site in order to discuss the various permits that will be required. Please note that tree removal on sites containing critical areas may first require a tree cutting permit, and the illegal removal of trees may result in penalties and steep fines (ECDC 18.45.070, ordinance ##8828). ` May 6 , 2014 Kevin Garrett, AICP, Planner Name, Title Signature Date
