The City of Sammamish uses the information provided in the SEPA (State
Environmental Policy Act) Checklist to help determine whether the
environmental impacts of a proposal are significant.
The information is also helpful to determine if there are mitigation measures
that will address the probable significant impacts or if an environmental
impact statement will be needed to further analyze the proposal.
Complete and accurate answers often avoid delays with the SEPA process as
well as later in the decision-making process.
INSTRUCTIONS FOR APPLICANTS
The checklist questions apply to all parts of your project/proposal, even if
you plan to do them over a period of time or on different parcels of land.
Please answer each question accurately and carefully, to the best of
y
our knowledge.
You may need to consult with an agency specialist or private
consultant for some questions.
If you run out of space on the form, please attach additional pages.
Use “not applicable/does not apply" only when you can explain why
it does not apply and not when the answer is unknown.
Attach any additional information that will help describe you
r
project/proposal or its environmental effects including additional
s
tudies and reports.
Th
e City may ask you to explain your answers or provide additional
information reasonably related to determining if there may be significant
adverse impact.
