The northern side of your property contains and is adjacent to a steep slope down to Lund's Gulch. This slope is steep enough to be considered both an Erosion Hazard Area and a Landslide Hazard Area, which causes your property to be subject to the applicable critical areas regulations of Edmonds Community Development Code (ECDC) Chapters 23.40 and 23.80. Please note that I have not fully assessed your property in order to determine if any other critical areas (i.e. streams, wetlands, etc.) are located on or adjacent to your property; however, at a minimum your property is subject to the critical areas regulations related to Erosion and Landslide Hazard Areas. Due to the fact that a critical area is located on/adjacent to your property, the City's critical areas regulations preclude any activities/impacts that degrade the function and value of the critical area as follows: ECDC 23.10.130 General regulations — Environmentally sensitive areas and critical areas. A. Location. 1. Environmentally sensitive areas include steep slopes; marshes, bogs, and swamps, floodplains; streams; spawning beaches; and other areas exhibiting serious constraints on development and/or significant possibility of biotic productivity. , 2. Critical areas include fish and wildlife habitat conservation areas; frequently flooded areas; geologically hazardous areas; streams; and wetlands. B. Development Limitations. All uses, developments, and activities on sites containing environmentally sensitive areas and/or critical areas must comply with all applicable local, state, and federal laws pertaining to development in these areas. In addition, the site must be specifically designed so that the hazards from or impact on the environmentally sensitive area and/or critical area will be mitigated. C. Additional Authority. In addition to any other authority the city may have, the city is hereby authorized to condition or deny a proposed use, development, or activity or to require site redesign because of hazards associated with the use, development or. activity on or near an environmentally sensitive and/or critical area, and/or the effect of the proposal on the environmentally sensitive area and/or critical area. [Ord. 3318 § 3, 2000]. Additionally, unless specifically listed as an allowed activity in ECDC 23.40.220, no alteration of a critical area is allowed without proper approval. An alteration of a critical area is defined as follows: ECDC 23.40.320: `Alteration" means any human -induced action which changes the existing condition 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 ofgravel; modifying for surface water management purposes; or any other Page 1 of 2 human activity that changes the existing landforms, vegetation, hydrology, wildlife or wildlife habitat value of critical areas. Since dumping of landscaping debris on a steep slope is not listed as an allowed activity in ECDC 23.40.220 and since it would result in an alteration of a critical area, it is not allowed. Thus, you cannot dump landscaping debris (or any other materials) on the steep slope on/adjacent to the northern side of your property. If you have any questions, please do not hesitate to contact me via phone at (425) 771-0220 or via email at Jen.Machueaa,edmondswa. p-ov.

An en•,:,-.jnmental impact statement (EIS) must be prepared for all proposals with probable significant adverse inipaets on the quality of the environment. The purpose of IhiS checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be dune) and to help the agency decide whether an EIS is required. Instnrctions for Applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agen- cies use .this checklist to cletcrmine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best de- scription you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, ;you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not ap- ply". Complete answers to the questions no", may avoid unnecessary delays later. Sono questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. AnsN-er these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach an)- additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional in- formation reasonably related to determining if there may be significant adverse impact.
