HomeMy WebLinkAboutECF_SEPA Environmental Checklist - completed_v1 SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 1 of 11 SEPA 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. A. Background 1.

Environmental Elements 1. Earth a. General description of the site: Residential property with steep slope b. What is the steepest slope on the site (approximate percent slope)? < 90%. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? The soils on the site consist of dense soil derived from weathered sandstone from the Renton Formation (Tr). The presence of shallow bedrock is a mitigating factor in regards to stability of the slope at the northern extent of the site. It is our interpretation that the slope is comprised of bedrock, which is evidenced by local geologic mapping, and because the slope is currently at inclinations steeper than a soils’ natural angle of repose. Per our geotechnical engineers’ opinions, no additional mitigation is required for slope stability or deck support. See GEO Group Northwest, Inc. - Drainage Evaluation Report (March 25, 2022). 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. Does not apply. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. None known. 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. None proposed. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. There was a concern of potential erosion occurring; however, the geotechnical evaluation and review has determined and certified that the location is stable. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? 2,756 SF, or 55% of lot square footage, per R-6 zoning requirements.
