ENVIRONMENTAL CHECKLIST JEFFERSON COUNTY DCD 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: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) The proposed construction sequence will involve: establishing temporary access in the County right of way (machinery to be walked over existing rock to beach, next to concrete boat ramp), removing existing bulkhead (113 feet) and adding 45 feet of new bulkhead to the south end of existing bulkhead. The process includes: excavating keyway, installing rockery bulkhead armor rocks, installing filter fabric, placing spalls backfill and removing the temporary site access from the County right of way once construction is completed. All rock shall conform to requirements set out in Arc Construction Guideline (2013) Section 2.01.1 Rock Quality. Rock size shall be between one man and three man. Larger rocks shall be placed at the bottom and smaller rocks shall be placed at the top. Existing rocks may be incorporated into the repair, provided that they conform to the specifications. The area between the bulkhead and existing bank shall be filled with clean angular 4 -inch to 6 -inch spalls. Filter fabric shall be non -woven and conform to recommendations made in the Arc Rockery Construction Guidelines (2013). The bottom row of rocks shall be placed in a keyway at least three feet below the natural beach elevation. The keyway subgrade shall be inclined slightly towards the existing bank to the west. Bulkhead rocks shall be placed in a manner where any one rock does not rest on one single rock of the layer below. The face of the rockery bulkhead shall be inclined at a batter of 1H: 4V. Filter fabric shall extend from the top of the existing bank and down over the existing soils and then between the backfill and the rockery bulkhead. Thickness of the backfill between the rockery bulkhead and the existing bank shall be a minimum of 12 inches. Spalls shall be placed at a slope of 1.5H: 1V to 211: 1V from the back of the rockery bulkhead to the existing bank. 12. Location of the proposal.
