This information is also helpful to determine if available avoidance, minimization, or compensatory mitigation measures will address the prob able 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. 1 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/Checklist-guidance SEPA Environmental checklist September 2023 Page 2 (WAC 197-11-960) A.

Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes, explain. This application is being done as part of the Williams ADU / Garage project. No other projects are needed / planned. 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. We have had the following reports completed in preparation for this project. 1. Channel Migration Study 2. Geotechnical Study 3. Wetland and Stream Assessment 4. Drainage Report 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. 2 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist- guidance/SEPA-Checklist-Section-A-Background SEPA Environmental checklist September 2023 Page 3 (WAC 197-11-960) None are known at this time. 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 th ose answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) We are planning to build a separate garage with living unit above (ADU) with 2 bedrooms and bathroom. The square footage is planned to be 980 SF. The building will be used for extra vehicles (trailer and boat) and for visiting relatives. We do not plan to rent out the ADU. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans requi red by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The location of the ADU/Garage will be behind the existing residence and the driveway will be to the side of the house where an existing gate is located. The new building will be close to the existing house because it must be outside of the 100-year flood zone. This is shown on the site plan. The site plan also takes into account boundaries with the neighbors property. [Site plan is attached with this SEPA Checklist] B. Environmental Elements 1. Earth Find help answering earth questions3 a. General description of the site: There are no wetlands on or visible from the subject property. The property is primarily lawn grass between the house patios and the streambank of the Cedar River. The soils are Pilchuck fine sandy, which is a non-hydric fluvial soil that does not meet the criteria for a hydric soil. The elevation from the river to the house is gradual, 68’ by the river and 76’ by the location of the planned ADU. Circle or highlight one: Flat, rolling, hilly, steep slopes, mountainous, other: As stated above, the elevation from river to planned location of the house is 8’. This elevation is gradual over a 200’+ distance from the river. Site Plan shows the elevation from river to planned site. 3 https://ecology.wa.gov/regulations-permits/sepa/environmental-review/sepa-guidance/sepa-checklist- guidance/sepa-checklist-section-b-environmental-elements/environmental-elements-earth SEPA Environmental checklist September 2023 Page 4 (WAC 197-11-960) b. What is the steepest slope on the site (approximate percent slope)? There is a 2’ incline by the river and then there is a gradual slope up to the proposed site, appr. 200’+ from the river shore. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, 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. The soils are Pilchuck fine sandy, which is a non-hydric fluvial soil that does not meet the criteria for a hydric soil. The taxonomic classification is Mixed, Mesic Dystric Xeropsamments. The typical Pedon “A” horizon depth is 0-20 inches of sand. The drainage classification is “somewhat excessively drained”. Soils color are 10YR 4/3, as determined with a Munsell color chart in the field. [From the Wetland and Stream Assessment dated 11/20/21]. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. We do not know of any history of unstable soils by the property. There is a hillside across the river from the house that is monitored by a public agency. e. Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. The construction area will be over 200’ from the river edge by the current resident house. The proposed Garage / ADU will be apprx. 980 SF (35’x28’). There will be no basement, just cement slab. f. Could erosion occur because of clearing, construction, or use? If so, generally describe. There should not be any erosion since the construction site is over 200’ from the river bank. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The current plot is 37,744 SF. The planned building is 980 SF. That results in 2.6% of the property. All other surfaces on the site (residence, driveway and concrete paving) equal approx.. 5000 SF equals approx.. 13.25%. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any. We have planned the building outside of the 100 flood plan and over 200’ away from the river. SEPA Environmental checklist September 2023 Page 5 (WAC 197-11-960) 2. Air Find help answering air questions4 a. What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. We will be using general construction methods and the only machines used will be to clear the area for the concrete slab and moving in the materials. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. Not to our knowledge. We are not asking for any special materials that would require special processing. c. Proposed measures to reduce or control emissions or other impacts to air, if any: We have not planned for any special controls since the construction size is limited and using standard materials. 3. Water Find help answering water questions5 a. Surface: Find help answering surface water questions6 1. Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names.

Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. The current septic system will be replaced with a new septic system, the design has been submitted to the City of Renton as part of our application paperwork. c. Water Runoff (including stormwater): 1. Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. The first feasible BMP is to mitigate runoff from the proposed impervious areas of Full Infiltration via an infiltration drywell. This drywell will catch flows from the proposed rooftop as well as the proposed driveway. Per the requirement for Full Infiltration, pollution generating impervious surfaces may be part of the contributing surface runoff to the infiltration facility if said runoff is treated for water quality. There are no other feasible BMPs to mitigate runoff from the proposed driveway due to site constraints (buffers, geometry etc…). Thus, although water quality treatment is not required per the core requirements criteria, it is required since we are routing 7 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist- guidance/SEPA-Checklist-Section-B-Environmental-elements/Environmental-elements-3-Water/Environmental- elements-Groundwater SEPA Environmental checklist September 2023 Page 7 (WAC 197-11-960) pollution generating runoff to an infiltration facility. As such, a Contech storm filter catch basin is proposed to be placed in the proposed driveway to collect runoff, treat it, and then release it into the proposed drywell for Full Infiltration. [From Drainage Report dated 12/17/24]. 2. Could waste materials enter ground or surface waters? If so, generally describe. Routing pollution generating runoff to an infiltration facility. As such, a Contech storm filter catch basin is proposed to be placed in the proposed driveway to collect runoff, treat it, and then release it into the proposed drywell for Full Infiltration. [From Drainage Report dated 12/17/24]. 3. Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. Drainage proposed will only effect the residence of applicants, no effect on neighboring properties. d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: An infiltration drywell will catch flows from the proposed rooftop as well as the proposed driveway. 4.

Supplemental sheet for nonproject actions Find help for the nonproject actions worksheet20 Do not use this section for project actions. Because these questions are very general, it may be helpful to read them in conjunction with the list of the elements of the environment. When answering these questions, be aware of the extent the proposal, or the types of activities likely to result from the proposal, would affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms. 1. How would the proposal be likely to increase discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise? The building is primarily a garage and excess living space when needed for family visits. The only water discharge is rain runoff and there will be no toxic or hazardous substances. The only noise will be normal living conditions. • Proposed measures to avoid or reduce such increases are: Filters that will be installed to treat the rain runoff. 19 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist- guidance/SEPA-Checklist-Section-C-Signature 20 https://ecology.wa.gov/regulations-permits/sepa/environmental-review/sepa-guidance/sepa-checklist- guidance/sepa-checklist-section-d-non-project-actions SEPA Environmental checklist September 2023 Page 16 (WAC 197-11-960) How would the proposal be likely to affect plants, animals, fish, or marine life? No affect on animals, fish or marine life. We will need to take down two trees. • Proposed measures to protect or conserve plants, animals, fish, or marine life are: We will be planting additional trees along the edge of the property. 2. How would the proposal be likely to deplete energy or natural resources? This property will not be used as a main residence, so energy use is limited. • Proposed measures to protect or conserve energy and natural resources are: Will continue to use correct lighting appropriate for the area. 3. How would the proposal be likely to use or affect environmentally sensitive areas or areas designated (or eligible or under study) for governmental protection, such as parks, wilderness, wild and scenic rivers, threatened or endangered species habitat, historic or cultural sites, wetlands, floodplains, or prime farmlands? No affect • Proposed measures to protect such resources or to avoid or reduce impacts are: None needed 4. How would the proposal be likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses incompatible with existing plans ? The project is over 200’ away from the river shoreline • Proposed measures to avoid or reduce shoreline and land use impacts are: Far enough away from river shoreline 5. How would the proposal be likely to increase demands on transportation or public services and utilities? No impact. • Proposed measures to reduce or respond to such demand(s) are: None needed 6. Identify, if possible, whether the proposal may conflict with local, state, or federal laws or requirements for the protection of the environment. No conflict. The site is far enough away from the river and there are no other protected areas.
