HPA_2018_SEPA_Checklist.doc Purpose of Checklist: The State Environmental Policy Act (SEPA), chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this 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 done) and to help the agency decide whether an EIS is required. Instructions for Applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine 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 description 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 apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer 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 any 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 information reasonably related to determining if there may be significant adverse impact. Use of checklist for nonproject proposals: For nonproject proposals complete this checklist and the supplemental sheet for nonproject actions (Part D). the lead agency may exclude any question for the environmental elements (Part B) which they determine do not contribute meaningfully to the analysis of the proposed nonproject actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposer," and "affected geographic area," respectively. a. background 1.

General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other: The topography of the City varies greatly from location to location; generally Edmonds slopes westerly to the Sound with moderate to steep slopes. (STAFF COMMENTS) b. What is the steepest slope on the site (approximate percent slope)? 30% to 40% at site MDC-1 and SHC-6 (see Table 1) (STAFF COMMENTS) c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, and muck)? If you know the classification of agricultural soils, specify them and note any agricultural land of long term commercial significance and whether the proposal results in removing any of these soils. Predominant soils found across the City of Edmonds are: Alderwood gravelly sandy loam and Everett gravelly sandy loam. Other soils with much smaller areal extent are: Kitsap silt loam, McKenna gravelly sandy loam and Mukilteo muck. (STAFF COMMENTS) d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. MDC-1 is within the North Edmonds Earth Subsistence and Landslide Hazard Area (ESHLA) however, maintenance work is not typically of geotechnical nature. (STAFF COMMENTS) e.

Proposed measures to reduce or control erosion, or other impacts to the earth, if any: To minimize erosion from occurring within the project areas, any enviornmentally sensitive work will occur during the dry season (summer months). If there is the potential of rainfall on exposed soils which could erode and transport sediment to a watercourse, these soils will be covered with straw, jute erosion control cloth, or other BMP’s deemed to mitigate said sedimentation. Several staff maintain CESCL certification and can direct the selection and implementation of erosion control BMPs as needed. (STAFF COMMENTS) 2. air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, and industrial wood smoke) during construction and when the project is completed?

(STAFF COMMENTS) (2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Yes, see Table 1 and Figure 1. The work will consist of a variety of actions to maintain flow by removing obstructions, cleaning trash racks, and removing sediment. Except for removing sediment at the Perrinville Creek diversion structure (site PRC-2), all work will be done using hand tools only. Site PRC-2 requires a stream bypass, fish exclusion and excavation with a backhoe which historically has removed approximately 16 cubic yards of rocks and sediment per cleaning.
