Bethany Corner SEPA Checklist Page 1 of 24 Renton, Washington DRS Project No. 16062 CITY OF RENTON ENVIRONMENTAL CHECKLIST Bethany Corner 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. © 2016 D.

Flat, rolling, steep slopes, mountainous other. In general, the majority of the property has slopes of less than 15%. The Site slopes west towards adjacent parcels. b. What is the steepest slope on the site (approximate percent slope)? There is one area where the slope is approximately 15%. This area is located along the northern property line. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classifi- cation of agricultural soils, specify them and note any prime farmland. The soils on the Site are mapped in the Soil Survey of King County, Washington, prepared by the U.S. Department of Agriculture, Soil Conservation Service and has classified the Site as Alderwood material, slopes 8-15% (AgC). Additionally, see attached Geotechnical Report dated December 16, 2016. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Per the City of Renton’s COR Maps, there are no landslide hazard or seismic hazard areas on Site. Topography and the geotechnical report suggest the potential for a landslide should be characterized as very low. © 2016 D. R. STRONG Consulting Engineers Inc. Bethany Corner SEPA Checklist Page 6 of 24 Renton, Washington e. Describe the purpose, type, and approximate quantities and total affected area of any filling or grading proposed. Indicate source of fill. The purpose of the site grading will be to construct the utilities, local access streets, finished grade pad elevations and drainage tract. Approximately 11 c.y. of cut and 9,966 c.y. of fill is computed for the Project. The net volume is approximately 9,955 c.y. of fill. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. There could be a short-term increase in the potential for on-site erosion where soils are exposed during site preparation and construction; however, the Project will comply with all applicable erosion control measures, short term and long term. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Approximately 59% of the Site will be covered by impervious surfaces. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any. A temporary erosion control plan will be implemented at the appropriate time. Erosion control measures may include the following: hay bales, siltation fences, temporary siltation ponds, controlled surface grading, stabilized construction entrance, and other measures, which may be used in accordance with requirements of the City of Renton. 2.

Off-site sources of emissions or odors are those that are typical of residential neighborhoods. These will include automobile emissions from traffic on adjacent roadways and fireplace emissions from nearby homes. c. Proposed measures to reduce or control emissions or other impacts to air, if any. The Washington Clean Air Act requires the use of all known, available, and reasonable means of controlling air pollution, including dust. Construction impacts will not be significant and could be controlled by measures such as washing truck wheels before exiting the site and maintaining gravel construction entrances. In addition, dirt-driving surfaces will be watered during extended dry periods to control dust. 3. WATER a. Surface. © 2016 D. R. STRONG Consulting Engineers Inc.
