21.04.050 Designation of responsible official
A. For those proposals for which the City is a lead agency,
the responsible official shall be the Community Development
Director or their designee or such other person as the Mayor may
designate in writing.
B. For all proposals for which the City is a lead agency, the
responsible official shall make the threshold determination,
supervise scoping and preparation of any required Environmental
Impact Statement (EIS), and perform any other functions assigned

SEPA Rules that have been adopted by reference.
(Ord. 2711 §3, 2023; Ord. 1344 §2, 1985; Ord. 1331 §4, 1984)
21.04.060 Lead agency - Determination - Responsibilities
A. The responsible official shall determine the lead agency
for that proposal under WAC 197-11-050 and WAC 197-11-922
through 197-11-940, unless the lead agency has been previously
determined or the responsible official is aware that another
department or agency is in the process of determining the lead

B. When the City is not the lead agency for a proposal, all
departments of the City shall use and consider as appropriate
either the Determination of Non-Significance (DNS) or the final EIS
of the lead agency in making decisions on the proposal. No City
department shall prepare or require preparation of a DNS or EIS
in addition to that prepared by the lead agency unless the City
determines a supplemental environmental review is necessary
under WAC 197-11-600.
C. If the City, or any of its departments, receives a lead
agency determination made by another agency that appears
inconsistent with the criteria of WAC 197-11-922 through 197-11-

the lead agency and for which one or more State agencies have
jurisdiction, the City may elect to transfer the lead agency duties
to the State agency. The State agency with jurisdiction appearing
first on the priority list in WAC 197-11-936 shall be the lead
agency. To transfer lead agency duties, the responsible official
must transmit a notice of the transfer, together with any relevant
information available on the proposal, to the appropriate State
agency with jurisdiction. The responsible official shall also give
notice of the transfer to the private applicant and any other
agencies with jurisdiction over the proposal.

21.04.110 Categorical exemptions - Flexible thresholds for Minor New Construction
A. The City establishes the following exempt levels for minor
new construction as allowed under WAC 197-11-800(1)(c) and (d),
based upon local conditions:
1. For single-family residential projects, up to thirty (30)
dwelling units;
2. For multifamily residential projects, up to two
hundred (200) dwelling units;
3. For agricultural structures, up to forty thousand
(40,000) square feet;
4. For office, school, commercial, recreational, service
or storage buildings, up to thirty thousand (30,000) square feet;
5. For parking facilities, up to ninety (90) parking
spaces;
6. For fills or excavations, up to one thousand (1,000)
cubic yards. All fill or excavation, of any quantity, necessary for an
exempt project in subsections 1 through 4 of this section shall be
exempt.
B. The exemptions in this subsection apply except when the
project:
1. Is undertaken wholly or partly on lands covered by
water;
2. Requires a license governing discharges to water
that is not exempt under RCW 43.21C.0383;
3. Requires a license governing emissions to air that is
not exempt under RCW 43.21C.0381 or WAC 197-11-800 (7) or
(8); or
4. Requires a land use decision that is not exempt
under WAC 197-11-800(6).
C. Whenever the City establishes new exempt levels under
this section, it shall send them to the Department of Ecology,
Headquarters Office, Olympia, Washington, 98504 under WAC
197-11-800(1)(c).
(Ord. 2711 §4, 2023; Ord. 2502 §1, 2016; Ord. 2173 §1, 2007; Ord. 1344 §6, 1985; Ord. 1331 §11, 1984)
21.04.120 Categorical exemptions - Determination
A. When the City receives an application for a license or, in
the case of governmental proposals, a department initiates a
proposal, the responsible official shall determine whether the
license and/or the proposal is exempt. The determination that a
proposal is exempt shall be final and not subject to administrative
review. If a proposal is exempt, none of the procedural
requirements of this chapter shall apply to the proposal.
B. In determining whether or not a proposal is exempt, the
responsible official shall made certain the proposal is properly
defined and shall identify the governmental license required. If a
proposal includes exempt and nonexempt actions, the responsible
official shall determine the lead agency, even if the license
application that triggers the consideration is exempt.
C. If a proposal includes both exempt and nonexempt
actions, the City may authorize exempt actions prior to compliance
with the procedural requirements of this chapter, except that:
1. The City shall not give authorization for:
a. Any nonexempt action;
b. Any action that would have an adverse
environmental impact; or
c. Any action that would limit the choice of
reasonable alternatives.
2. The responsible official may withhold approval of an
exempt action that would lead to modification of the physical
environment, when such modification would serve no purpose if
the nonexempt actions were not approved; and
3. The responsible official may withhold approval of
exempt actions that would lead to substantial financial
expenditures by a private applicant when the expenditures would
serve no purpose if the nonexempt actions were not approved.
(Ord. 1331 §12, 1984)
21.04.130 Threshold determination - Review at conceptual stage
A. If the City’s only action on a proposal is a decision on a
building permit or other license that requires detailed project plans
and specifications, the applicant may request in writing that the
City conduct environmental review prior to submission of the
detailed plans and specifications.
B. In addition to the environmental documents, an applicant
may be required to submit the following information:
1. Conceptual site plans and building plans;
2. Other information as the responsible official may
determine;
3. Environmentally sensitive areas studies as
described in TMC 21.04.140 for sensitive areas.
(Ord. 1599 §7(2), 1991; Ord. 1344 §5, 1985; Ord. 1331 §9, 1984)
TITLE 21 – ENVIRONMENTAL REGULATIONS
Produced by the City of Tukwila, City Clerk’s Office Page 21 –6
21.04.140 Threshold determinations - Environmental checklist
A. A completed environmental checklist shall be filed at the
same time as an application for a permit, license, certificate or
other approval not exempted by this chapter. The checklist shall
be in the form of WAC 197-11-960.
B. If the site is an environmentally critical area, a critical area
study that meets the requirements of TMC Chapter 18.45 may be
required. The SEPA official may waive any study requirements
determined to be unnecessary for review of a particular use or
application. Funding for a qualified professional, selected and
retained by the City, shall be paid for by the applicant to review the
geotechnical reports on Class 2 and Class 3 landslide, seismic and
coal mine hazard areas if the geotechnical report indicates Class
3 or Class 4 characteristics, and will be required in all Class 4
landslide hazard areas. Applicants may also be required to pay for
peer review of wetland and watercourse studies per TMC Section
18.45.040.E.
C. A checklist is not needed if the City and the applicant
agree an EIS is required, SEPA compliance has been completed,
or SEPA compliance has been initiated by another agency.
D. The City shall use the environmental checklist to
determine the lead agency and, if the City is the lead agency, for
making the threshold determination.
E. For private proposals, the applicant is required to
complete the environmental checklist. The City may provide
information as necessary. For City proposals, the department
initiating the proposal shall complete the environmental checklist
for that proposal.
F. The City may decide to complete all or part of the
environmental checklist for a private proposal, if either of the
following occurs:
1. The City has technical information on a question or
questions that is unavailable to the private applicant; or
2. The applicant has provided inaccurate information
on previous proposals or on proposals currently under
consideration.
(Ord. 2711 §5, 2023; Ord. 1599 §7(3), 1991;
Ord. 1344 §7, 1985; Ord. 1331 §13, 1984)
21.04.150 Threshold determinations - Mitigated DNS
A. The responsible official may issue a Determination of
Non-Significance (DNS) based on conditions attached to the
proposal by the responsible official or on changes to, or
clarifications of, the proposal made by the applicant.
B. An applicant may request in writing early notice of
whether a Determination of Significance (DS) is likely. The
request must:
1. Follow submission of a permit application and
environmental checklist for a nonexempt proposal for which the
department is lead agency; and
2. Precede the City’s actual threshold determination for
the proposal.
C. The responsible official’s written response to the request
for early notice shall:
1. State whether the City currently considers issuance
of a DS likely and, if so, indicate the general or specific areas of
concern that are leading the City to consider a DS; and
2. State that the applicant may change or clarify the
proposal to mitigate the indicated impacts, and may revise the
environmental checklist and/or permit application as necessary to
reflect the changes or clarifications.
D. When an applicant submits a changed or clarified
proposal, along with a revised environmental checklist, the City
shall base its threshold determination on the changed or clarified
proposal.
1. If the City indicated specific mitigation measures in
its response to the request for early notice, and the applicant
changed or clarified the proposal to include those specific
mitigation measures, the City shall issue and circulate a
Determination of Non-Significance if the City determines that no
additional information or mitigation measures are required.
2. If the City indicated areas of concern, but did not
indicate specific mitigation measures that would allow it to issue a
DNS, the City shall make the threshold determination, issuing a
DNS or DS as appropriate.
3. The applicant’s proposed mitigation measures,
clarifications, changes or conditions must be in writing and must
be specific.
4. Mitigation measures which justify issuance of a
mitigated DNS may be incorporated in the DNS by reference to
agency staff reports, studies or other documents.
E. The City shall not act upon a proposal for which a
mitigated DNS has been issued for 15 days after the date of
issuance.
F. Mitigation measures incorporated in the mitigated DNS
shall deemed conditions of approval of the licensing decision and
may be enforced in the same manner as any term or condition of
the permit or enforced in any manner specifically prescribed by the
City. Failure to comply with the designated mitigation measures
shall be grounds for suspension and/or revocation of any license
issued.
G. If the City’s tentative decision on a permit or approval
does not include mitigation measures that were incorporated in a
mitigation DNS for the proposal, the City should evaluate the
threshold determination to assure consistency with WAC 197-11-
340(3)(a) relating to the withdrawal of a DNS.
H. The City’s written response under 21.04.150C shall not
be construed as a determination of significance. In addition,
preliminary discussion of clarification or changes to a proposal, as
opposed to a written request for early notice, shall not bind the City
to consider the clarifications or changes in its threshold
determination.
(Ord. 1599 §7(4), 1991; Ord. 1344 §8, 1985; Ord. 1331 §14, 1984)

21.04.156 Designating a development as a planned action
A. The Director of the Department of Community
Development shall be authorized to designate a specific
development proposal which is eligible to be a planned action, has
mitigated all of its significant adverse impacts, and is consistent
with the Comprehensive Plan, as a planned action.
B. This designation shall be final, with no administrative
appeals.
(Ord. 1853 §8, 1998)
21.04.158 Planned action development review
process
Designation of a planned action would relieve the application
from any SEPA review including a threshold determination, any
final threshold determination, public notice of SEPA action, and
any administrative appeals. A notice of complete application
would NOT be sent for Type 1 applications which choose the
planned action option.
(Ord. 1853 §9, 1998)

Chapter 197-11.
B. The DEIS and FEIS or SEIS shall be prepared at the
City’s option by the City staff, the applicant, or by a consultant
approved by the City. If the responsible official requires an EIS for
a proposal and determines that someone other than the City will
prepare the EIS, the responsible official shall notify the applicant
immediately after completion of the threshold determination. The
responsible official shall also notify the applicant of the City’s
procedure for EIS preparation, including approval of the draft and
final EIS prior to distribution.
C. The City may require an applicant to provide information

calendar days from the date of issuance of a Declaration of
Significance. The following periods shall be excluded from this
365-day period:
1. Any period of time during which the applicant has
been requested by any City department, agency or hearing body
with jurisdiction over some aspect of the EIS to correct plans,
perform required studies, or provide additional information. The
period shall be calculated from the date the applicant is notified of
the need for additional information until the earlier of (a) the date
the department, agency or hearing body determines whether the
additional information satisfies the request, or (b) 14 days aft er the
date the information has been provided to the department, agency
or hearing body. If the department, agency or hearing body
determines that the action by the applicant is insufficient, it shall
notify the applicant of the deficiencies and the procedures of this
section shall apply as if a new request for information had been
made.
2. Any additional time period for preparation of the EIS
agreed upon by the Department and the applicant.

requiring an EIS and the responsible official determines the EIS
shall be prepared by employees of the City, the City may charge
and collect a reasonable fee from any applicant to cover costs
incurred, including overhead, by the City in preparing the EIS. The
responsible official shall advise the applicant of the projected costs
for the EIS prior to actual preparation.
b. The responsible official may determine that the
City will contract directly with a consultant for preparation of an
EIS, or a portion of the EIS, for activities initiated by some persons

directly to the applicant. Such consultants shall be selected by the
City. Also, the City will charge an administrative fee in addition to
the consultant fees, according to the adopted Land Use Fee
Schedule.
c. The applicant shall pay the projected amount to
the City prior to commencing work. The City will refund the excess,
if any, at the completion of the EIS. If the City’s costs exceed the
projected costs, the applicant shall immediately pay the excess. If

responsible official shall refund any fees collected under a. or b. of
this subsection which remain after incurred costs, including

the cost of meeting the public notice requirements of this chapter
