ENV ENVIRONMENTAL CHECKLIST
Planning Division
1055 South Grady Way-Renton, WA 98057
Phone: 425-430-7200 | www.rentonwa.gov
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: 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: [help] 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 -
