HomeMy WebLinkAboutECF_SEPA_Checklist_221014_v1 SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 1 of 12 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 [HELP] 1.

Site plan and vicinity maps are included with the SEPA permitting package. B. Environmental Elements [HELP] 1. Earth [help] SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 3 of 12 a. General description of the site: The project site is generally flat, and fully developed with the existing WSADA office on the westerly portion of the site, and parking on the easterly portion of the site. In the project area, the site slopes gently up from the foundation of the offices to the roadways to the north and west. (circle one): Flat, rolling, hilly, steep slopes, mountainous, other _____________ b. What is the steepest slope on the site (approximate percent slope)? ±14% at the northwesterly corner of the site abutting Southwest Grady Way. Average slope throughout the developed portion of the site is ±3%. 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. A geotechnical report prepared by E3RA, dated April 12, 2012 is included with the SEPA permitting package. Per the report, on-site soils consist of “fill, consisting of medium dense to dense silty sand with varying amounts of gravel, organics, and construction debris.” The fill was recorded as being 4 to 5 feet in thickness at the northern edge of the site down to 1 foot or less at the southern edge. This fill was topped with 3 to 6 inches of topsoil. Under the site is an alluvial layer comprised of soft to medium stiff silt and loose, silty fine sand that extended 13½ to 24 feet below grade from east to west. Beneath the alluvial layer is a second alluvial layer of medium dense to very dense sand with gravel. A supplementary geotechnical engineering letter specific to this project, dated 09/26/2022 has also been provided. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No. 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. Our conceptual site plan will disturb approximately 4,000 SF of surface; and will involve earthwork of approximately ±40 CY cut and ±40 CY fill, for a total earthwork of ±80 CY . Fill will be comprised of structural fill obtained from local quarry, as sourced by the earthwork contractor. Structural fill will be in accordance with Washington State Department of Transportation standard specifications. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Earthwork to prepare site for proposed building and permanent site features will generally be lower than existing grade, and contained within the excavation footprint. Installation of temporary erosion and sedimentation control (TESC) devices will be required prior to clearing and grading activity. The proposed building, paved surfaces, and landscaping will provide permanent stabilization for all exposed surfaces. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Approximately 78% of the total site area will be covered with impervious surfaces upon completion of construction. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: As described in section “f” above, TESC measures will be installed to minimize erosion during construction per the CSWPPP included in the Civil Construction permit SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 4 of 12 package. After construction, the site will be permanently stabilized with buildings, pavement, and landscaped surfaces. 2. Air [help] a. What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed?

None proposed. 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 is the only runoff anticipated on-site. The roof runoff from the proposed building expansion will connect to the existing roof drain. No new or replaced pollution generating hard surfaces are proposed for this project. Stormwater from new/replaced surfaces will be detained in accordance with the City of Renton Stormwater Manual and discharged to the City stormwater system. 2) Could waste materials enter ground or surface waters? If so, generally describe. The site will be equipped with a stormwater system designed to collect surface water runoff and convey it to the City system via a stormwater detention feature. The existing biorention cell will treat storm water runoff from Raymond Avenue. 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. No, all surface water is currently tributary to the City stormwater system in Raymond Ave SW via the same outfall as before. d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: We are proposing to maintain the existing treatment system on the site. The larger Stormtech storage chamber will remain unmodified. The 48” diameter storage pipe providing storage for the bioretention pond in the southwest corner of the site will be replaced with a shorter pipe, larger diameter pipe that provides equivalent storage. Stormwater discharged from the site will also be treated. 4. Plants [help] a.
