HomeMy WebLinkAboutECF_SEPA Checklist_230329_v1.pdfSEPA Environmental checklist (WAC 197-11-960) January 2023 Page 1 of 17 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.

Will the project or proposal use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. The project will not use or occur in the immediate vicinity of water, rail, or air transportation. e. How many vehicular trips per day would be generated by the completed project or proposal? If known, indicate when peak volumes would occur and what percentage of the volume would be trucks (such as commercial and nonpassenger vehicles). What data or transportation models were used to make these estimates? The traffic analysis conducted for this SEPA Checklist reflects conditions with the Hazen High School Portables Placement complete and occupied to the increased enrollment capacity up to 1,694 students, a net increase of 51 students compared to the capacity at the time of the last permitted classroom addition in 2011. Based on daily trip generation rates published for High Schools (Land Use 525) by the Institute of Transportation Engineers (ITE), the school with the added portables is estimated to generate a net increase of about 100 trips per day (50 in, 50 out). The peak traffic volumes would continue to occur in the morning just before classes begin (a net increase of 17 trips [12 in, 5 out] between 6:30 and 7:30 a.m.) and in the afternoon around dismissal (a net increase of 12 trips [4 in, 8 out] between 2:00 and 3:00 p.m.). Currently, the school is served by 9 school buses in the morning and 10 buses in the afternoon; according to the District’s Transportation staff, no change to the number of buses is anticipated. Other truck trips expected to continue serving the site include deliveries of food and supplies, trash and recycling pick-up, and occasional maintenance. Overall, school buses and small trucks likely represent about 2 to 3 percent of the total daily traffic. For more information about the anticipated school traffic generation, refer to the Renton School District’s Hazen High School Portables Placement – Transportation Analysis (Heffron Transportation, Inc., March 1, 2023). f.
