ORD 18-856 - Relating to Floodplain Development and Permitting ProcessesORDINANCE NO. 18-856
AN ORDINANCE of the City of Federal Way, Washington, relating
to floodplain development and permitting processes within the City;
amending FWRC 19.142.040, 19.142.050, 19.142.060; and repealing
Chapter 15.15 FWRC. (Amending Ordinance Nos. 06-536, 09-593,
and 09-597.)
WHEREAS, the City recognizes the need to periodically modify Title 19 of the Federal
Way Revised Code ("FWRC"), "Zoning and Development Code," in order to conform to state
and federal law, codify administrative practices, clarify and update zoning regulations as deemed
necessary, and improve the efficiency of the regulations and the development review process;
and
WHEREAS, this ordinance, containing amendments to development regulations and the
text of Title 19 FWRC, has complied with Process VI review, Chapter 19.80 FWRC, pursuant to
Chapter 19.35 FWRC; and
WHEREAS, it is in the public interest for the City Council to adopt amended
development regulations for Chapter 19.142 FWRC regarding development within frequently
flooded areas; and
WHEREAS, the State developed new language regarding flood prevention that has not
been incorporated into Chapter 19.142 FWRC; and
WHEREAS, the State Department of Ecology, through its Community Assistance Visit,
informed the City that the new State language needed to be added to the chapters of the FWRC
that regulate development within the areas designated as floodplains by the Federal Emergency
Management Agency ("FEMA"); and
Ordinance No. 18-856 Page I of 13
WHEREAS, the absence of such language necessitates amendment to the FWRC to
incorporate the State -required language; and
WHEREAS, Chapters 15.15 and 19.142 FWRC are identical, and such duplication is not
necessary and has the potential to create inconsistencies when those chapters are amended in the
future; and
WHEREAS, the repeal of Chapter 15.15 FWRC eliminates the duplicative chapter; and
WHEREAS, the Planning Commission conducted public discussion of these code
amendments on June 20, 2018; and
WHEREAS, an Environmental Determination of Nonsignificance ("DNS") was properly
issued for the Proposal on September 13, 2018, and no comments or appeals were received and
the DNS was finalized on September 27, 2018; and
WHEREAS, the Planning Commission properly conducted a duly noticed public hearing
on these code amendments on September 19, 2018 and forwarded a recommendation of approval
to the City Council as follows: (1) repeal Chapter 15.15 FWRC; (2) amend FWRC 19.142.040
by adding and amending definitions for "Development" and "Start of Construction"; (3) amend
FWRC 19.142.050 by changing the reference to the correct flood study title; (4) amend FWRC
19.142.060 to indicate that the section is related to floodplain development permits and to
identify those activities that do not require a floodplain development permit; and (5) amend
FWRC 19.142.060 by adding required actions that must be accomplished in order to receive a
floodplain development permit, including identifying conditions under which a habitat impact
assessment must be performed, and when a habitat mitigation plan must be completed; and
Ordinance No. 18-856 Page 2 of 13
WHEREAS, the Land Use & Transportation Committee of the Federal Way City Council
considered these code amendments on October 1, 2018, and recommended adoption of the text
amendments as recommended by the Planning Commission.

will benefit the City as a whole by clarifying requirements of State regulation and correcting
textual duplication within the Code that will mitigate the need for interpretation when reviewing
projects proposed within the identified floodplain.
(b) These code amendments comply with Chapter 36.70A RCW, Growth
Management.
(c) These code amendments are consistent with the intent and purpose of Title 19 and
Title 15 FWRC and will implement, and are consistent with, the applicable provisions of the
Federal Way Comprehensive Plan.
(d) These code amendments bear a substantial relationship to, and will protect and
not adversely affect, the public health, safety, and welfare.
(e) These code amendments have followed the proper procedure required under the
Federal Way Revised Code.
Section 2. Conclusions. Pursuant to Chapter 19.80 FWRC and Chapter 19.35 FWRC, and
based upon the recitals and the findings set forth in Section 1, the Federal Way City Council
Ordinance No. 18-856 Page 3 of 13
makes the following Conclusions of Law with respect to the decisional criteria necessary for the
adoption of the proposed amendments:
(a) The proposed FWRC amendments are consistent with, and substantially
implement, the following Federal Way Comprehensive Plan goals and policies:
Goals:
NEG 1 To preserve the City's natural systems in order to protect public health,
safety, and welfare, and to maintain the integrity of the natural
environment.
NEP4 The City will continue to work with internal departments, state and
regional agencies, neighboring jurisdictions, and tribes to protect
environmentally critical areas and the City's natural environment.
NEP6 Mitigation sequencing steps, which begin with avoiding impacts
altogether by not taking certain action or parts of an action, should be
applied to all projects where impacts to environmentally critical areas are
proposed.
NEP7 Implement and periodically update environmentally critical area
regulations consistent with Best Available Science while also taking into
consideration the City's obligation to meet urban -level densities and other
requirements under the GMA.
NEG6 To prevent the loss of life, property, and habitat in frequently flooded
areas.
NEP41 New improvements should not be located in floodplains unless fully
mitigated via best building practices within areas of special flood hazard,
shallow flooding, coastal high hazard, and floodways. FWCP — Chapter
Nine, Natural Environment Revised 2015 IX -10
NEP42 Any approved construction should follow the mitigation recommendations
of a Habitat Assessment report.
(b) The proposed FWRC amendments bear a substantial relationship to the public
health, safety, and welfare because they provide clarification and additions to the sections of the
Ordinance No. 18-856 Page 4 of 13
Code designed to prevent flood damage to life and property located in identified floodplains
within the City of Federal Way.
(c) The proposed amendments are in the best interest of the public and the residents
of the City of Federal Way because they eliminate a duplication within the Code, which can
result in inconsistent implementation when amendments are made to such sections within the
Code, and provide greater safety, clarity, and certainty to applicants wishing to develop projects
within floodplains.

Section 5. FWRC 19.142.050 is hereby amended to read as follows:
19.142.050 General provisions.
(1) Application of chapter. This chapter shall apply to all areas of special flood hazards within
the jurisdiction of Federal Way. The areas of special flood hazard identified by the Federal
Insurance Administration in a scientific and engineering report entitled "The Flood Insurance
Study for FederalWay King County, Washington and Incorporated Areas" dated May 16, 1995,
and any revisions thereto, with an accompanying flood insurance rate map (FIRM), and any
revisions thereto, are hereby adopted by reference and declared to be a part of this chapter. The
flood insurance study and the FIRM are on file at Federal Way City Hall. The best available
information for flood hazard area identification as outlined in FWRC 19.142.070 shall be the
basis for regulation until a new FIRM is issued that incorporates data utilized under
FWRC 19.142.070.
(2) Penalties for noncompliance. No structure or land shall hereafter be constructed, located,
extended, converted, or altered without full compliance with the terms of this chapter and other
applicable regulations.
(3) Summary abatement. Whenever any violation of this chapter causes or creates a condition
which constitutes or contributes to an immediate and emergent threat to the public health, safety
or welfare or to the environment, the director may summarily and without prior notice abate the
condition. Notice of such abatement, including the reason for it, shall be given to the person
responsible for the violation as soon as reasonably possible after abatement. The costs of such
summary abatement shall be recoverable via procedures for recovery of abatement costs as set
forth in Chapter 1.15 FWRC, Civil Enforcement of Code.
(4) Abrogation and greater restrictions. This chapter is not intended to repeal, abrogate, or
impair any existing easements, covenants, or deed restrictions. However, where this chapter and
another ordinance, easement, covenant, or deed restriction conflict or overlap, whichever
imposes the more stringent restrictions shall prevail.
(5) Interpretation. In the interpretation and application of this chapter, all provisions shall be:
(a) Considered as minimum requirements;
(b) Liberally construed in favor of the governing body; and
Ordinance No. 18-856 Page 9 of 13
(c) Deemed neither to limit nor repeal any other powers granted under state statutes.
(6) Warning and disclaimer of liability. The degree of flood protection required by this chapter is
considered reasonable for regulatory purposes and is based on scientific and engineering
considerations. Larger floods can and will occur on rare occasions. Flood heights may be
increased by manmade or natural causes. This chapter does not imply that land outside the areas
of special flood hazards or uses permitted within such areas will be free from flooding or flood
damages. This chapter shall not create liability on the part of Federal Way, any officer or
employee thereof, or the Federal Insurance Administration for any flood damages that result
from reliance on this chapter or any administrative decision lawfully made hereunder.
Section 6. FWRC 19.142.060 is hereby amended to read as follows:
19.1.42.060 Development Activities Subiect to Floodplain Development Permits.
(1) Floodplain Ddevelopment permit required. A floodplain development permit shall be
obtained before construction or development begins within any area of special flood hazard
established in FWRC 19.142.050(1). The permit shall be for all structures including
manufactured homes, as set forth in FWRC 19.142.040, and for all development including fill
and other activities, also as set forth in FWRC 19.142.040.
(2) Non -development Activities. Activities that do not meet the definition of "Development" in
this chapter are allowed in the regulatory floodplain without the need for a floodplain
development permit under this chapter, provided all other federal, state, and local requirements
are met. The following are examples of activities not considered development or manmade
changes to improved or unimproved real estate:
(a) Routine maintenance of landscaping that does not involve grading, excavation, or
fillip
(b) Removal of noxious weeds and hazard trees and replacement of nonnative vegetation
with native vegetation;
(c) Normal maintenance of structures, such as re-roofingand replacing siding, as long as
such work does not qualify as a substantial improvement;
(d) Normal maintenance of above ground public utilities and facilities, such as replacing
downed power lines;
(e) Normal street and road maintenance, including filling potholes, repaving, and installing
signs and traffic signals, but not including expansion of paved areas; and
(f) Normal maintenance of a levee or other flood control facility prescribed in the
operations and maintenance plan for the levee or flood control facility.
Ordinance No. 18-856 Page 10 of 13
(3) Other Activities. All other activities not described in subsection (2) of this section are
allowed, as long as a floodplain development permit is approved, and, if required, as long as such
activities meet all the other requirements of this chapter and the other provisions of the FWRC.
(24) Application for floodplain development permit. Application for a floodplain development
permit shall be made and shall include, but not be limited to, plans in duplicate drawn to scale
showing the nature, location, dimensions, and elevations of the area in question, existing or
proposed structures, fill, storage of materials, drainage facilities, and the location of the
foregoing. Specifically, the following information is required:
(a) Elevation in relation to mean sea level, of the lowest floor (including basement) of all
structures recorded on a current elevation certificate (FEMA Form 81-31) with Section B
completed by the city of Federal Way building official;
(b) Elevation in relation to mean sea level to which any structure has been floodproofed;
(c) Certification by a registered professional engineer or architect that the floodproofing
methods for any nonresidential structure meet floodproofing criteria in

(d) Description of the extent to which a watercourse will be altered or relocated as a
result of proposed development.
(35) Designation of the administrator. The director or designee is hereby appointed to administer
and implement this chapter by granting or denying development permit applications in
accordance with its provisions. The director shall:
(a) Review all development applications to determine that the requirements of this
chapter have been satisfied;
(b) Review all development applications to determine that all necessary permits have
been obtained from those federal, state, or local governmental agencies from which prior
approval is required; and
(c) Review all development applications to determine if the proposed development is
located in the floodway. If located in the floodway, assure that the encroachment
provisions of FWRC 19.142.160(1) are met.
(6) Project requirements. If the project is located in the regulatory floodplain and includes
activities not listed in FWRC 19.142.060(2), the application shall include a habitat impact
assessment completed by a professional biologist. If that assessment determines that impacts
upon the habitat would result from the project, the application shall also include a habitat
mitigation plan. The habitat assessment and the habitat mitigation plan shall be performed as
described in FEMA's Regional Guidance for Floodplain Habitat Assessment and Mitigation in
the Puget Sound Basin, 2013, and any revisions thereto.
Ordinance No. 18-856 Page 11 of 13
