Alder Street Purpose of checklist: Governmental agencies use this checklist to help determine whether the environmental impacts of your proposal are significant. This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use "not applicable" or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision- making process. 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. Instructions for Lead Agencies: Please adjust the format of this template as needed. Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals: For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please completely answer all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead agency may exclude (for non-projects)questions in Part B - Environmental Elements—that do not contribute meaningfully to the analysis of the proposal.

Name of proposed project, if applicable: Sullivan Pier, Ramp, and Float Replacement Project 2. Name of applicant: Larry Sullivan 20631 SE 162nd Way / Renton, WA 98059-9072 425-566-2580 3. Address and phone number of applicant and contact person: Integrated NW Construction, Inc/Sarah Kupers/60 N Lake Cushman Rd, Suite 109, Hoodsport, WA 98584!360-968-3441 psa@integratednwconstruction.com. 4. Date checklist prepared: 7/22/2024 5. Agency requesting checklist: Mason County 6. Proposed timing or schedule (including phasing, if applicable): Upon receipt of all regulatory permits, work shall be conducted during the Lake Cushman draw-down 7. Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes, explain. No 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. None 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. No 10. List any government approvals or permits that will be needed for your proposal, if known. Mason County - Shoreline Exemption, Building Permit WDFW- HPA 11. 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.) Install a replacement pier, ramp, float, and mooring buoy alternative on the Sullivan's Lake Cushman shoreline property. The 4'x29' pier will be supported by(8) 6"diameter Schedule 80 piles, driven to refusal depth. The pier will be fully grated with Eco-grate 62 to achieve 60% open area. A 3'x6' fully grated aluminum pre-fab ramp will span between the pier and float. The 8'x20'float will be attached to (4) 6"diameter Schedule 80 guide piles, driven to refusal depth. This float will be fully grated with Eco-grate 62 to achieve 60% open area. A float cradle will be installed to prevent the float from resting on the bottom which includes 4 stub piles (6" diameter Schedule 80 piles, driven to refusal depth) and 6x8 AYC beams. The mooring buoy alternative will meet Tacoma Power requirements. The existing pier, ramp, (2)floats, and all piles plus concrete footings will be fully removed prior to installation of replacement structure. This will be a reduction in 137.33 SF of over-water coverage and development in the shoreline buffer.
