SEPA Environmental checklist September 2023 Page 1 (WAC 197-11-960) SEPA 1 Environmental Checklist 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. 1 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/Checklist-guidance Docusign Envelope ID: 104DBDA6-11CD-4791-91FF-7DA2A96942C7 SEPA Environmental checklist September 2023 Page 2 (WAC 197-11-960) A.

You do not need to repeat those answers on Docusign Envelope ID: 104DBDA6-11CD-4791-91FF-7DA2A96942C7 SEPA Environmental checklist September 2023 Page 4 (WAC 197-11-960) this page. (Lead agencies may modify this form to include additional specific information on project description.) The subject property is located at 1828 NE 20th Street, Renton, WA (Figure 1). The applicant is proposing a new single-family home (4,549 sf) and an accessory dwelling unit (ADU – 738 sf) for a total floor area of 5,287 sf. Access to the lot is proposed to be retained via the existing lot flagpole that extends north to the homesite from NE 20th ST. Re-Align Environmental (2023, 2024) identified a wetland that is located along the western and southern portions of the parcel. A rating score of 14 indicates that the wetland is a Category IV wetland. The City’s Critical Areas Regulations at 4-3-050G Development Standards prescribes a 50-foot buffer for this wetland. (Figure 2). Table 1 provides a summary of the wetland and buffer areas. Table 1 – Critical Areas Summary Critical Area Area (sf) Area (ac) Wetland Onsite 10,050 0.23 Offsite 9,100 0.21 Total 19,150 0.44 Buffer Offsite 3,378 0.08 Onsite Vegetated 9,802 0.23 Onsite Driveway 6,250 0.14 Total 19,430 0.45 The proposed development has been located on the northern portion of the site, such that the proposed driveway and buildings avoid the wetland buffer at the homesite (Figure 3). The flagpole, which contains the existing, overgrown driveway, passes through the wetland buffer and within 2 – 20 feet of the existing wetland boundary. At 4-3-050I Alterations to Critical Areas Buffers, the City code provides criteria for buffer averaging. Sections 4-3- 050I(3)(a)(2) and 4-3-050I(3)(b)(4) specifically require that buffer reductions or averaging may not reduce the buffer to less than 75% of its standard width. In this case, with a 50-foot wetland buffer, the buffer could be reduced to a minimum of 37.5 feet. The existing driveway, and therefore the proposed driveway, would be well-within the reduced 37.5-foot buffer. As a result, the driveway represents an existing, non-conforming use and the development of the new driveway will require a Reasonable Use Variance for the development in the buffer. Staff comments on the preliminary submittal also noted this in their discussion of critical areas (City of Renton, 2021). Based on the site plan in Figure 3 and the areas described in Table 1, the onsite wetland and buffer areas are summarized in Table 2. Table 2 also outlines the proposed treatment of the wetland and buffer for the proposed development. Docusign Envelope ID: 104DBDA6-11CD-4791-91FF-7DA2A96942C7 SEPA Environmental checklist September 2023 Page 5 (WAC 197-11-960) Table 2 – Onsite Wetland and Buffer Areas Critical Area Area (sf) Area (ac) Proposal Wetland 10,050 0.23 Enhancement Buffer - Onsite Vegetated 9,802 0.23 Restoration Buffer - Onsite Driveway 6,250 0.14 Replace with new driveway Total 16,052 0.37 The proposed development would not include any impact to the wetland area. However, due to the configuration of the lot, with a flagpole driveway, the proposed site plan would redevelop the existing driveway in the pipestem, resulting in 0.14 acre of impact to the buffer. As compensation for this unavoidable buffer impact, enhancement of the 0.23-acre wetland is proposed to increase plant diversity and to improve wildlife forage opportunities in the wetland. Restoration of the 0.23-acre, remaining buffer area outside of the driveway is also proposed. With 0.46 acre of restoration/ enhancement proposed, the ratio of buffer impact to mitigation would be 3.3:1. Stormwater from the proposed new and improved impervious surface (house/ADU and driveway turn-around) is proposed to be infiltrated in two areas outside of the wetland buffer (Figure 4) (C2MY Engineers, LLC., 2024). 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 required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The subject property parcel (no. 3343903201) is located at 1828 NE 20th Street (Figure 1), within the Residential-4 (R-4) Zone and Residential Low Density (RLD) Comprehensive Plan Land Use of Designation. The total area of the site is 51,067 SF. The parcel is a vacant “flag lot” (defined in RMC 4-11-120) that accesses via a “flagpole” that extends from NE 20th ST. The site is located in T23N R5E S5.

Earth Find help answering earth questions3 a. General description of the site: The parcel is surrounded by single-family residential development on the south and eastern boundaries, and undeveloped forest and shrub areas on the north and west. The site contains evidence of past development, including an existing driveway in a flagpole that is overgrown with Himalayan blackberry (Rubus armeniacus) as well as a concrete building foundation in the center of the site. The previous landowner, Mr. Terry Dutro of Masterbuilder Construction, reports that he removed several buildings on the property because the buildings were unsafe (Dutro, 2018). The site is currently vegetated with a dense cover of young trees and shrubs over most of the site. Circle or highlight one: Flat, rolling, hilly, steep slopes, mountainous, other: Gently sloping northeast to southwest. b. What is the steepest slope on the site (approximate percent slope)? Approximately 12% slope in the very northeast corner of the site. Pioneer Engineers, Inc. (2024), the geotechnical report, states: “In accordance with RMC 4-3-050G(5a) and RMC 4-3-050G(5b), the site is located in a flat area with an overall ground slope less than 15 percent; therefore, it pertains to a classified low landslide (“LL”) hazard area.” (p-1) And “In accordance with RMC 4-3-050G(5c), the site is located in an area of low erosion hazard (“EL”) due to its overall site grade less than 15 percent.” (p-2) 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. As documented in Re-Align Environmental (2023) and C2MY Engineers, LLC. (2024), there are two soil types on the subject property (Figure 6): • InC - Indianola loamy sand, 5 to 15 percent slopes; and • Sm—Shalcar muck. The following presents a summary of each soil found on the site, based on the descriptions in Re-Align Environmental (2023) and C2MY Engineers, LLC. (2024). 3 https://ecology.wa.gov/regulations-permits/sepa/environmental-review/sepa-guidance/sepa-checklist-guidance/sepa-checklist-section-b-environmental-elements/environmental-elements-earth Docusign Envelope ID: 104DBDA6-11CD-4791-91FF-7DA2A96942C7 SEPA Environmental checklist September 2023 Page 7 (WAC 197-11-960) InC - Indianola loamy sand, 5 to 15 percent slopes Indianola loamy sand is found on terraces, eskers and kames and is derived from sandy glacial outwash. This soil is found between 0 and 980 feet in elevation. This soil is somewhat excessively well drained and exhibits a depth to water table of over 80 inches. Indianola is known to contain inclusions of the hydric Norma series along drainageways. Sm—Shalcar muck Shalcar muck is found on floodplains and is derived from herbaceous organic material and/or alluvium. This soil is typically located in areas with a slope of 0% to 1%. The soil is very poorly drained and exhibits a water table at the soil surface. Shalcar muck is a hydric soil. No agricultural soils are present on the property. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No. See 1.b 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. A detailed grading plan has not been prepared, as yet. It is expected that the site would be graded, as necessary, to re-develop the existing driveway and to construct the house/ADU, outside of the wetland and buffer area. This would include excavation for foundations and utilities and redistribution of any excess material locally at the site. This cut/fill is expected to balance onsite, with no import or export of soil. f. Could erosion occur because of clearing, construction, or use? If so, generally describe. Yes. Bare soil areas and stockpiles could be subject to erosion from rainfall and surface water flows during construction and until final soil stabilization. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The project proposes to add a total of new and replaced impervious surface of 13,822 sf, or 27% of the parcel. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any. Standard erosion and sediment control measures will be implemented to minimize erosion of soils and to prevent sediment transport off of the worksite. These include: • Silt Fence or wattles to prevent run-on into bare soil, and to capture mobilized sediment; • Mulching or covering temporary bare soil areas; • A construction entrance at NE 20th St.; and • Permanent soil stabilization, including seeding, landscape plantings, and mulching.

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. Any construction related emissions will be generated by vehicles or construction equipment as exhaust. Operations and maintenance related emissions would be generated by vehicles traveling to and from the site. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. No. c. Proposed measures to reduce or control emissions or other impacts to air, if any: The proposed home and ADU will use electricity for heat, hot water, and cooking. Therefore, no natural gas-related emissions are expected. 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. If appropriate, state what stream or river it flows into. See A.8. No streams or other water bodies are present on or near the subject property. As described in Re-Align Environmental (2023, 2024), a wetland is present on the property. 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. See A.8. The proposed site plan will require the redevelopment of an existing driveway in a flagpole (Figure 3). The driveway is immediately adjacent to the wetland on an adjacent parcel. No direct impacts to the wetland are proposed. However, the location of the driveway will not meet the standards for the wetland buffer. This checklist has been prepared to support a wetland variance to authorize the redevelopment of the driveway. 4 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist- guidance/SEPA-Checklist-Section-B-Environmental-elements/Environmental-elements-Air 5 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist- guidance/SEPA-Checklist-Section-B-Environmental-elements/Environmental-elements-3-Water 6 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-Surface-water Docusign Envelope ID: 104DBDA6-11CD-4791-91FF-7DA2A96942C7 SEPA Environmental checklist September 2023 Page 9 (WAC 197-11-960) 3. Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. None. The new driveway will be built over the existing driveway in the wetland buffer. No material will be placed in the wetland. 4. Will the proposal require surface water withdrawals or diversions? Give a general description, purpose, and approximate quantities if known. No. 5. Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. No. The site is located in Flood Zone X - See Figure 7 (C2MY Engineers, LLC., 2024). 6. Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground: Find help answering ground water questions7 1. Will groundwater be withdrawn from a well for drinking water or other purposes? If so, give a general description of the well, proposed uses and approximate quantities withdrawn from the well. Will water be discharged to groundwater? Give a general description, purpose, and approximate quantities if known. No. The proposed residence and ADU will connect to City water (Figure 11). 2. Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (domestic sewage; industrial, containing the following chemicals…; agricultural; etc.). 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. No waste material is expected to be discharged from septic tanks, as the proposed residence and ADU will connect to City sewer (Figure 11). Stormwater from new and improved impervious surfaces is proposed to be directed to infiltration trenches outside of the wetland buffer. The new and replaced PGIS pavement area is greater than 5,000 s.f., therefore water quality treatment is required. For the impermeable driveway turn-around, a Storm Filter will be provided to remove pollutants from stormwater before collection and distribution to the infiltration trench. Permeable pavement will be used for the driveway in the flagpole (Figure 4 - See C2MY Engineers, LLC. (2024)) 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 Docusign Envelope ID: 104DBDA6-11CD-4791-91FF-7DA2A96942C7 SEPA Environmental checklist September 2023 Page 10 (WAC 197-11-960) 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. Stormwater from new and improved impervious surfaces is proposed to be directed to infiltration trenches outside of the wetland buffer. The new and replaced PGIS pavement area is greater than 5,000 s.f., therefore water quality treatment is required. For the impermeable driveway turn-around, a Storm Filter will be provided to remove pollutants from stormwater before collection and distribution to the infiltration trench. Permeable pavement will be used for the driveway in the flagpole (Figure 4). 2. Could waste materials enter ground or surface waters? If so, generally describe. No. The proposed single-family residential development is not expected to generate any waste materials that could enter surface or ground waters. 3. Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. No. The proposed development has been designed to maintain the existing drainage pattern of the previous homesite, where surface water flows south/southwest from the developed site, through the wetland buffer, and into the wetland (Figures 3 and 4). d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: See 3.c. 4. Plants Find help answering plants questions a. Check the types of vegetation found on the site: ☒ deciduous tree: alder, maple, aspen, other ☒ evergreen tree: fir, cedar, pine, other ☒ shrubs ☒ grass ☐ pasture ☐ crop or grain ☐ orchards, vineyards, or other permanent crops. ☒ wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other ☐ water plants: water lily, eelgrass, milfoil, other ☒ other types of vegetation – blackberry infestation b. What kind and amount of vegetation will be removed or altered? Docusign Envelope ID: 104DBDA6-11CD-4791-91FF-7DA2A96942C7 SEPA Environmental checklist September 2023 Page 11 (WAC 197-11-960) The arborist report (Seeley, 2024) describes the trees that will be removed for the development of the site. The arborist report states that there are 24 Significant trees and 4 Landmark trees on the property (Pacific Arboriculture, 2024). CPH (2024b) and Pacific Arboriculture (2024) provide the tree replacement plan. Re-Align Environmental (2023) and CPH (2024a) describe the proposed wetland enhancement and buffer restoration plans (see A.11). In addition to these trees, development of the site will require removal of the dense blackberry thicket covering the existing driveway, as well as herbaceous species, including invasive species, on the homesite. c. List threatened and endangered species known to be on or near the site. None. Figure 9 shows the WDFW Priority Habitat and Species (PHS) listing for the project site and vicinity. The PHS shows no listings for the project area. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any. See 4.b. e. List all noxious weeds and invasive species known to be on or near the site. • Himalayan Blackberry (Rubus armeniacus) severe infestation in the flagpole driveway. • Reed Canarygrass (Phlaris arundinacea) minor infestation in the homesite and flagpole driveway areas. • English Holly (Ilex aquifolium) scattered occurrences. Note: Any invasive species in the wetland or wetland buffer are intended to be removed. It is expected that blackberry will continue to be an issue along the eastern property line because the infestation is present along the eastern parcels. 5. Animals Find help answering animal questions8 a. List any birds and other animals that have been observed on or near the site or are known to be on or near the site. Examples include: • Birds: hawk, heron, eagle, songbirds, other: Crow (Corvus brachyrhynchos) Stellar’s Jay (Cyanocitta stelleri) • Mammals: deer, bear, elk, beaver, other: 8 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist-guidance/SEPA-Checklist-Section-B-Environmental-elements/Environmental-elements-5-Animals Docusign Envelope ID: 104DBDA6-11CD-4791-91FF-7DA2A96942C7 SEPA Environmental checklist September 2023 Page 12 (WAC 197-11-960) Black-Tailed Deer (Odocoileus hemionus columbianus) Eastern Gray Squirrel (Sciurus carolinensis) • Fish: bass, salmon, trout, herring, shellfish, other: No aquatic species b. List any threatened and endangered species known to be on or near the site. None. Figure 9 shows the WDFW Priority Habitat and Species (PHS) listing for the project site and vicinity. The PHS shows no listings for the project area. c. Is the site part of a migration route? If so, explain. No. Figure 9 shows the WDFW Priority Habitat and Species (PHS) listing for the project site and vicinity. The PHS shows no listings for the project area. d. Proposed measures to preserve or enhance wildlife, if any. 1.) The wetland and its remaining buffer will be included in a Critical Areas easement. 2.) The wetland is proposed to be enhanced and the remaining buffer is proposed to be restored, as described in A.11 and summarized in Table 2. 3.) A 4-foot tall, wildlife passable fence (e.g., wood rail fence) will be installed along the wetland buffer boundary. 4.) The goal of the wetland enhancement and buffer restoration is to remove the invasive species, re-vegetate the remaining onsite buffer area with native, riparian species, and to increase the habitat complexity/forage species in the wetland. Please refer to Re- Align Environmental (2023 and 2024) and CPH (2024a) for details of the enhancement/restoration plan. e. List any invasive animal species known to be on or near the site. None. 6. Energy and natural resources Find help answering energy and natural resource questions9 a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. Electricity will be used for heating, hot water, and cooking. No gas service is proposed. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. 9 https://ecology.wa.gov/Regulations-Permits/SEPA/Environmental-review/SEPA-guidance/SEPA-checklist-guidance/SEPA-Checklist-Section-B-Environmental-elements/Environmental-elements-6-Energy-natural-resou Docusign Envelope ID: 104DBDA6-11CD-4791-91FF-7DA2A96942C7 SEPA Environmental checklist September 2023 Page 13 (WAC 197-11-960) No. The new buildings would not be tall enough to block solar panels on any adjacent houses. No solar panels are known to exist adjacent to this property. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any. No gas service is proposed in order to increase heating efficiencies (building heat, hot water, cook stove) and to minimize the carbon footprint of the proposed redevelopment of this site. 7. Environmental health Health Find help with answering environmental health questions10 a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur because of this proposal? If so, describe. No. The proposed use of the property is entirely single-family residential. No hazardous material, toxic chemicals, spills, or hazardous waste is expected with the redevelopment of the subject property. 1. Describe any known or possible contamination at the site from present or past uses. None known. 2. Describe existing hazardous chemicals/conditions that might affect project development and design. This includes underground hazardous liquid and gas transmission pipelines located within the project area and in the vicinity. None known. 3. Describe any toxic or hazardous chemicals that might be stored, used, or produced during the project's development or construction, or at any time during the operating life of the project. Gasoline or diesel fuel may be temporarily stored at the site during construction. A spill prevention and response plan would be in place for any stored fuels onsite. After project completion, the intent of the applicant is to maximize the use of electrical equipment and not to use gasoline-powered equipment for landscape and lawn maintenance.
