INTERLOCAL AGREEMENT FOR
EMERGENCY MEDICAL AND FIRE SERVICES AND SETTLEMENT
AGREEMENT REGARDING 2015 SERVICES
(1) Parties. The Parties to this Agreement (the “Agreement”) are the City of
Arlington, State of Washington (“Arlington”), a municipal corporation, and Snohomish
County Fire Protection District No. 21, a Washington municipal corporation, hereinafter
referred to as the “District.”
(2) Purpose. Arlington maintains and operates emergency medical services
(EMS) vehicles in accordance with Chapters 18.71 and 18.73 RCW and Chapter
246-976 WAC. Said vehicles are staffed by emergency medical technicians, paramedics,
and other Personnel by law. The purpose of this Agreement is to provide the services of
emergency medical technicians and other personnel as needed by the persons within the
boundaries of the District, as well as to resolve a disagreement regarding payment for
2015 services.
(3) Term. The term of this agreement shall be for two years, commencing
January 1, 2016, and terminating on December 31, 2017.
(4) ALS Duties of Arlington. During the term of this Agreement, Arlington
shall furnish advanced life support services to all persons within the geographical
boundaries of the District. The emergency medical services shall be rendered on the
same basis as such services are rendered to persons within the city limits of Arlington,
but Arlington assumes no liability for failure to provide such services by reason of any
circumstances beyond its control.
(5) Arlington to Comply with Statutes. It shall be the duty of Arlington
during the Agreement to provide vehicles and personnel conforming to the statutory and
regulatory requirements of Chapter 18.71 and 18.73 RCW and Chapter 246-976 WAC.
(6) State Certification Required. In the event for any reason Arlington shall
lose its required state certification of its medical services vehicles and personnel and
therefore become unable to perform the services required of it under this Agreement, it
shall immediately notify the District. During the period of such discontinuance of
service, the annual payment to be made by the District under Paragraph 15, below, shall
be reduced by 1/365th for each day or portion thereof that Arlington is unable to perform
such services.
(7) Arlington as Administrator. Arlington shall provide the administration
necessary to supervise the services provided under this Agreement, subject to its duties to
report to the District as set forth below.
(8) Assignment of Personnel and Equipment. Arlington shall be responsible
for the supervision, employment, termination, assignment and stationing of all personnel
and equipment required to perform its responsibilities under this Agreement.
(9) Payment for 2016 and 2017 ALS Services. District shall transfer to
Arlington for the ALS services to be provided by Arlington in 2016 and 2017 a sum
equal to sixty-five percent (65.0%) of all EMS tax levy receipts received by District.
Payment shall be by monetary payments by said District on June 15 and December 15 of
each year, with the first semi-annual payment for 2016 to occur within thirty (30) days
after ratification of this agreement by both parties.
(10) Payment for 2016 and 2017 Fire Services. The City shall respond to fire
calls within District 21 in 2016 and 2017 on a “Mutual Aid” basis without the payment
for fire services. If at any time the City responds more frequently to fire calls located in
District 21 than District responds to fire calls within the City, it shall so notify the District
and the District shall pay to City for fire calls after the date of notice by the City the sum
of three hundred fifty dollars ($350.00) per fire call within District 21 to which the City
responds, within thirty (30) days of said call.
(11) Liability. Each of the Parties to this Agreement shall, at all times, be
solely responsible for the acts or failure to act of its personnel only, and shall save and
hold the other Parties and their personnel harmless from all costs, expenses, losses, and
damages, including costs of defense, incurred as a result of any acts or omissions or the
Party’s personnel relating to the performance of this Agreement.
(12) Insurance. Arlington shall provide insurance coverage for operations
conducted under this Agreement. This agreement shall include all risk property
insurance, insuring Arlington’s equipment and building required for the provision of
services under this Agreement; general liability insurance, including errors and omissions
coverage, with policy limit of $5,000,000.00; complete auto insurance, including
comprehensive and collision coverage; and liability coverage with policy limits of
$5,000,000.00. Participation in a self-insurance pool with equivalent coverages shall
satisfy the requirement of this paragraph.
(13) Resolution of Disagreement Regarding Payment for Prior Services. As
further consideration for this agreement, the parties agree to resolve all disputes regarding
ALS and fire services provided during 2015 by Arlington to District pursuant to this
paragraph 13.
a. The District agrees to and shall pay to City the total sum of
$282,332.23 for 2015 ALS services and $8,400.00 for 2015 fire
services, for a total of $290,732.23, which shall be paid within thirty
(30) days after the ratification of this agreement by both parties, which
payment shall be payment in full of all sums owing and in full
settlement of all claims by and between each of the parties against the
other relating to the provision by Arlington of EMS and fire services to
the District during 2015. The City acknowledges possession of the
following checks/warrants previously tendered by District to the City
during negotiations:
The parties agree that Arlington shall cash these four warrants or, in
the event any of them may not be cashed due to County or banking
regulations, replacement warrants or checks as partial payment of the
sums set forth herein and that the District shall pay the additional
balance of $3,715.85 within thirty (30) days of the date of approval by
the governing bodies of the City and District of this agreement.
b. The District and City, each on behalf of themselves, their officers,
elected officials, successors and assigns agree to release any and all
claims, actions or causes of actions, and waive their rights to the same,
arising out of or relating to the provision of EMS and fire services by
Arlington to District. Except for enforcement of this Agreement, and
as otherwise provided in this Agreement, all legal and equitable issues
between and among the parties which were raised or which could have
been raised by and between the parties are deemed fully and finally
resolved.
(14) Relinquishment of license by Arlington. As further consideration for this
agreement, the City agrees to take all steps reasonably necessary to relinquish Arlington’s
basic life support (BLS) license for all of that portion of its service area within District 21
and shall not oppose District 21’s effort to secure a BLS license from the Department of
Health to serve residents of District 21. A condition of this relinquishment shall be an
understanding that the parties will work with SNOPAC to ensure that District 21’s closest
available unit or units other than City units shall be primary responders to BLS incidents
occurring within District 21. Neither party shall request changes to run cards or dispatch
priority without advance written notice to the other party.
(15) Modification. This Agreement represents the entire agreement between
the Parties. No attempted waiver of any of the provisions of this Agreement shall be
binding on any Party unless executed in writing by an authorized representative of said
Party. The Agreement shall not be modified, supplemented or otherwise affected by the
course of dealing between the Parties, and shall only be modified by written agreement of
all Parties.
(16) Benefits. This Agreement is entered into for the benefit of the Parties
hereto only and shall confer no benefits, direct or implied, on any third persons.
(17) Notices. All notices, requests, demands and other communications
required by this Agreement shall be in writing, and, except as expressly provided
elsewhere in this Agreement, shall be deemed to have been given at the time of delivery
if personally delivered or at the time of mailing if mailed by first class, postage pre-paid
and addressed to the receiving Party at the address as stated below or at such address as
any Party may designate at any time in writing.

(Attach page for additional space)
I am applying for consideration for the open position on the City of Arlington Civil Service Commission.
Upon inquiring to the city about the open position I learned that the outgoing member is a member of the
fire service community. I'm hopeful my background would serve to fill that upcoming void on the council
and balance well with the existing incumbent commission members. I've attached a copy of my resume
for review. My motivation to apply is to help in a small way serve the community in a volunteer capacity
by applying my background to serve the city and the local police and fire personnel who I hold in high
regard. I believe that ensuring transparent, fair and equitable hiring and promotional processes sets the
foundation for successful 911 operations as well as sets a basis for good public relations with
customers. Because of that I have been selected by my employer's HR department to serve on many
entry level and lateral hiring processes for firefighter and firefighter/paramedic positions. Thank you for
considering me for this position.
Lodging Tax applicants must attach a letter of support from the organization they are representing.

Subject: Civil Service Commission Applicants
As you may be aware, the Civil Service Commission has been operating as a two person
commission since April 1, 2016 when Jim Rankin’s term expired.
We advertised the vacancy two separate times and received a total of four applications.
A panel consisting of Civil Service Commissioner Steve Peterson, City Councilmember Marilyn
Oertle, City Councilmember Jesica Stickles, and myself held interviews on Tuesday June 28,
2016. The panel agrees that applicant Thad Hovis would be an asset with his fire background, is
interested in participating in the community, and would be a welcome addition to the vacant
Commission seat.
The panel recommends the appointment of Thad Hovis to the Civil Service Commission.

Once the document is finalized, a “fillable” format will be added to the City’s website
streamlining the process for applicants. Additionally, a meeting will be set with the
lodging tax advisory committee to review the application and rating process so the
committee is fully aware of the changes prior to reviewing applications for 2017 grant

20.44.034 ‐ Wireless communications facilities.
(a) Purpose. This section is intended to provide for a wide range of locations and options for wireless
communication providers while minimizing the visual impacts associated with wireless communication
facilities. It is also intended to encourage creative approaches in locating wireless communication
facilities so as to encourage facilities to blend in with the surroundings of such facilities. This section
is intended to work in concert with other sections of this code. If there is a conflict between wireless
facilities and other sections of this title then the most restrictive requirements apply.
(b) General Wireless Communication Facilities Development Standards. Unless other modified by
subsequent subsections, all wireless communication facilities shall be subject to the following
standards and requirements.
(1) Co-location Collocation on an existing support structures shall be encouraged and shall comply
with AMC 20.102. All wireless communication facilities support structures shall be built to
accommodate the location of two or more wireless communications facilities unless proved
infeasible. It shall be a continuing condition on all land use permits issued for a wireless
communication facility that the permit holder allows co-location collocation for reasonable
compensation. Co-location Collocation on an existing support structures or base stations shall be
exempt from zoning and development regulations, provided that permitted without an additional
permit, an application for an “Eligible Facilities Request” has been received and determined that
provided there is not substantial change to the existing support structure or base station, per the
criteria in AMC 20.102.
(2) Except for micro- and mini- facilities, shelters or cabinets used to house radio electronics
equipment and the associated cabling connecting the equipment shelter or cabinet to the facility
support structure shall be concealed, screened, camouflaged or placed underground.
(3) Wireless communication facilities shall be integrated through location and design to blend in with
the existing characteristics of the site to the extent practical. Existing on-site vegetation shall be
preserved or improved, and disturbance of the existing topography shall be minimized, unless
such disturbance would result in less visual impact of the site to the surrounding area.
(4) Federal Aviation Administration Jurisdiction. All applications for telecommunications facilities
regulated by this section must comply with all FAA requirements pertaining to operations of a
telecommunications device on or near the Arlington Airport, including FAA Part 77 regulations. It
is the responsibility of the applicant to be familiar with and meet relevant FAA regulations.
(5) All wireless telecommunications facilities are subject to Section 20.44.210 (Noise).
(6) Signals emanating to or from wireless communications equipment shall conform to current FCC
regulations with regard to avoiding the creation of interference to neighboring electronic or other
operating devices.
(7) FCC Preemption. In any proceeding regarding the issuance of a permit under the terms of this
section, federal law prohibits consideration of environmental effects of radio frequency emissions
to the extent that the proposed facilities comply with the Federal Communications regulations
concerning such emission.
(c) Development Standards for Micro Facilities.
(1) Micro facilities shall comply with Section 20.48.060 (Building Height Limitations), except when
installed completely within appurtenant structures exempted by Subsection (c) of that section.
(2) The permitted antenna height includes the wireless communication facility support structure.
(3) Structures that are nonconforming with respect to height may be used for the placement of micro
facilities providing they do not extend more than six feet above the existing structure. Placement
of an antenna on a nonconforming structure shall not be considered to be an expansion of the
nonconforming structure.
2nd Draft – 6/22/16
Page 2
(4) A micro facility shall be located on existing buildings, poles, or other existing support structures,
but only if the interior wall or ceiling immediately adjacent to the facility is not designated
residential space.
(5) The shelter or cabinet used to house radio electronic equipment shall be contained wholly within
a building or structure, or otherwise appropriately concealed, camouflaged or located
underground.
(6) In R-LMD, and R-MD zones, micro facilities for a specific wireless provider shall be separated by
a distance of at least one thousand three hundred twenty linear feet from other wireless
communications facilities.
(7) The facility shall also comply with the requirements of Subsection (b).
(d) Development Standards for Mini Facilities.
(1) Mini facilities shall comply with Section 20.48.060 (Building Height Limitations) except as follows:
Omni directional antennas may exceed the height limitation by ten feet, or in the case of
nonconforming structures, the antennas may extend ten feet above the existing structure. Panel
antennas may exceed the height limitation if affixed to the side of an existing nonconforming
building and blends in architecturally with the building. Placement of an antenna on a
nonconforming structure shall not be considered to be an expansion of the nonconforming
structure.
(2) A mini facility may be located on existing buildings, poles, or other existing support structures, but
only if the interior wall or ceiling immediately adjacent to the facility is not designated residential
space.
(3) The shelter or cabinet used to house radio electronic equipment shall be contained wholly within
a building or structure, or otherwise appropriately concealed, camouflaged or located
underground.

follows: Omni directional antennas may exceed the height limitation by fifteen feet, or in the case
of nonconforming structures, the antennas may extend fifteen feet above the existing structure.
Panel antennas may exceed the height limitation if affixed to the side of an existing building and
architecturally blends in with the building. Placement of an antenna on a nonconforming structure
shall not be considered to be an expansion of the nonconforming structure.
(2) The macro facility shall be the same color as the existing building, pole or support structure on
which it is proposed to be located unless the permit-issuing authority makes findings that a
different color would be less intrusive and better blend with the existing structure.
(3) A macro facility may be located on existing buildings, poles, or other existing support structures,
but only if the interior wall or ceiling immediately adjacent to the facility is not designated
residential space.
(4) The facility shall also comply with the requirements of Subsection (b).

LEGAL REVIEW:
DESCRIPTION:
The proposed ordinance regarding Floodplain Development Regulations was a total
rewrite of Chapter 20.64. Representatives of FEMA reviewed our existing Ordinance
and recommended a total rewrite in order to be in compliance with CFR 44 and NMFS
Biological Opinion and also make the ordinance easier to design to and comply with.
Several meetings with FEMA representatives took place during the rewrite, several
meetings (workshops) with the Planning Commission were held, and a Noticed Public
Hearing was held on July 7, 2016. The Planning Commission Findings of Facts will be
prepared as part of the Ordinance adoption.
HISTORY:
NFIP ESA History: 2003 FEMA was sued for failure to comply with ESA. 2004 Court
ruled that FEMA must consult with NMFS. 2006 FEMA provided a Biological
Evaluation that stated NFIP may affect but not adversely. 2008 NMFS issued a
Biological Opinion with jeopardy/adverse modification. As a result, FEMA
developed a program for local jurisdictions to satisfy the Reasonable & Prudent
Alternatives to its Floodplain Management Criteria, known as RPA Element 3. The
National Marine Fisheries Service (NMFS) reviewed and approved this approach. The
COA has opted for alternative 2, known as Door 2, which demonstrates that a
community’s existing plans and regulations provide equivalent protection to the
standards proposed in RPA Element 3. This requires verification and approval by
FEMA that existing plans and regulations provide the necessary protection.

Chapter 20.64 ‐ FLOODWAYS, FLOODPLAINS, DRAINAGE, AND EROSION FLOODPLAIN DEVELOPMENT
REGULATIONS
Sections:
Part I. ‐ Floodways and Floodplains Administrative Provisions
Part I. ‐ Floodways and Floodplains
20.64.010 ‐ Statutory authorization.
The legislature of the state of Washington has delegated the responsibility to local governmental units
to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry.
Therefore, the city of Arlington does ordain as follows:
(Ord. 1309 § 5(part), 2003)
20.64.020 ‐ Findings of fact.
(a) The flood hazard areas of Arlington are subject to periodic inundation which results in loss of life and
property, health, and safety hazards, disruption of commerce and governmental services,
extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of
which adversely affect the public health, safety, and general welfare. The Special Flood Hazard Areas
of Arlington encompass a very small area (0.02%) of the developable lands within the corporate limits
of the city. These areas are subject to periodic inundation of floodwaters due to storm surges and
runoff, which may result in property damage, public safety, disruption of commerce, and other
consequences.
(b) These flood losses are caused by the cumulative effect of obstructions in areas of special flood hazards
that increase flood heights and velocities, and when inadequately anchored, damage uses in other
areas. Uses that are inadequately floodproofed, elevated, or otherwise protected from flood damage
also contribute to the flood loss. The National Flood Insurance Program is adopted by the City of
Arlington, which aims to reduce the impact of flooding on private and public structures. It does so by
providing affordable insurance to property owners and by encouraging communities to adopt and
enforce floodplain management regulations. The efforts help mitigate the effects of flooding on new
and improved structures.
(c) On September 22, 2008, the National Marine Fisheries Service (NMFS) issued a Biological Opinion
that required changes to the implementation of the National Flood Insurance Program in order to meet
the requirements of the Endangered Species Act (ESA) in the Puget Sound Watershed. The City of
Arlington enacted regulations that allow development that meets the criteria specified in the Biological
Opinion as a “Door 2” Community.
(Ord. 1309 § 5(part), 2003)
20.64.030 ‐ Statement of purpose.
It is the purpose of this chapter to promote the public health, safety, and general welfare, and to
minimize public and private losses due to flood conditions in specific areas by provisions designed:
(1) To protect human life and health;
Commented [CY1]: Title change to reflect what the
ordinance regulates

Formatted: Centered
(2) To manage development in a manner reducing impacts to floodplain processes;
(3) To minimize expenditure of public money and costly flood control projects;
(4) To minimize the need for rescue and relief efforts associated with flooding and generally
undertaken at the expense of the general public;
(5) To minimize prolonged business interruptions;
(6) To minimize damage to public facilities and utilities such as water and gas mains, electric,
telephone and sewer lines, streets, and bridges located in areas of special flood hazard;
(7) To help maintain a stable tax base by providing for the sound use and development of areas of
special flood hazard so as to minimize future flood blight areas;
(8) To ensure that potential buyers are notified that property is in an area of special flood hazard;
and,
(9) To ensure that those who occupy the areas of special flood hazard assume responsibility for their
actions.
(Ord. 1309 § 5(part), 2003)
(Ord. No. 2011-030, § 1, 12-5-2011)
20.64.040 ‐ Methods of reducing flood losses.
In order to accomplish its purposes, this chapter includes methods and provisions for:
(1) Restricting or prohibiting uses which are dangerous to health, safety, and property due to water
or erosion hazards, or which result in damaging increases in erosion or in flood heights or
velocities; Regulating development in Special Flood Hazard Areas (SFHA);
(2) Requiring that uses vulnerable to floods, including facilities which serve such uses, all
development and land use activity be protected against flood damage at the time of initial
construction;
(3) Controlling the alteration of natural flood plains, stream channels, wetlands and natural protective
barriers, which help accommodate or channel flood waters;
(4) (3) Controlling Regulating filling, grading, dredging, and other development which may have
an adverse impact on flood waters increase flood damage; and
(5) (4) Preventing or regulating the construction of flood barriers that will unnaturally divert
floodwaters or may increase flood hazards in other areas.

restoring the structure to itsit’s its before damaged condition would equal or exceed fifty percent of the
market value of the structure before the damage occurred.
"Substantial improvement" means any repair, reconstruction, or improvement of a structure, the cost
of which equals or exceeds fifty percent of the market value of the structure either:
(1) Before the improvement or repair is started; or
(2) If the structure has been damaged and is being restored, before the damage occurred. For the
purposes of this definition "substantial improvement" is considered to occur when the first
alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or
not that alteration affects the external dimensions of the structure.
The term does not, however, include either:
(3) Any project for improvement of a structure to correct existing violations of state or local health,
sanitary, or safety code specifications which have been identified by the local code enforcement
official and which are the minimum necessary to assure safe living conditions, or
(d) Any alteration of a "historic structure," provided that the alteration would not preclude the structure's
continued designation as a "historic structure."
"Variance" means a grant of relief from the requirements of this chapter that permits construction in a
manner that would otherwise be prohibited by this chapter.

(Ord. No. 2011-030, §§ 3, 4, 12-5-2011)
20.64.060 ‐ Basis for establishing the areas of special flood hazard.
(a) The areas of special flood hazard identified by the Federal Insurance Administration in a scientific and
engineering report entitled "The Flood Insurance Study for Snohomish County and iIncorporated
Areas" (in which the city is incorporated) dated September 16, 2005, or as amended, with an
accompanying flood insurance rate map (FIRM), as amended, are hereby adopted by reference and
declared to be a part of this section. The flood insurance study and the FIRM are on file at Arlington
City Hall, 238 North Olympic, Arlington, Washington. The best available information for flood hazard
area identification as outlined in subsection (b) shall be the basis for regulation until a new FIRM is
issued which incorporates the data utilized under subsection (b).
(b) When base flood elevation data has not been provided (A and V Zones) in accordance with subsection
(a), the administrator shall use any base flood elevation and floodway data available from a federal,
state or other source, in order to comply with Section 20.64.180 (Specific Standards for Zones A1-30,
AH, and AE) and Section 20.64.190 (Specific Standards for Designated Regulatory Floodways).
(c) If such data are not already available, the administrator may rely on a licensed surveyor to provide
such information as necessary to reasonably ascertain said zones.

20.64.080 ‐ Interpretation.
In the interpretation and application of this chapter, all provisions shall be:
(1) Considered as minimum requirements;
(2) Liberally construed in favor of the governing body; and,
(3) Deemed neither to limit nor repeal any other powers granted under State statutes.
(Ord. 1309 § 5(part), 2003)
20.64.090 ‐ 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 cCity of Arlington, 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.

20.64.100 ‐ Supplementary information required with a permit application.
In addition to the standard information required with on a permit application, (Section 20.16.040,
Applications To Be Complete), the following information is also required for any permits proposing
development within a floodway or floodplain, watercourse alteration or relocation:
(1) Elevation in relation to mean sea level, of the lowest floor (including basement) of all structures;
(2) Elevation in relation to mean sea level to which any structure has been floodproofed;
(3) Elevation Certification by a registered professional engineer or architect. that the floodproofing
methods for any nonresidential structure meet the floodproofing criteria in Subsection

20.64.110 ‐ Conformance with Chapter 20.88 (Environmentally Critical Areas).
Wherever this section allows uses within a floodway or floodplain, that use must also be consistent
with Chapter 20.88 (Environmentally Critical Areas) and Chapter 20.92 (Shoreline Management) in terms
of both allowable use and location of use. In any case, wherever regulations in these two chapters conflict,
the more restrictive shall prevail. The explicit intent of this section is to not allow development that is
inconsistent with Chapter 20.88 or Chapter 20.92 to occur in the restricted areas or buffers required by that
chapter, even though it may seem permissible according to the regulations of this chapter.
(Ord. 1309 § 5(part), 2003)
(Ord. No. 2011-030, § 7, 12-5-2011)
20.64.120 110 ‐ Location of boundaries of floodplain and floodway districts.
(a) As used in this chapter, the terms floodplain and floodway refer in the first instance to certain areas
whose boundaries are determined and can be located on the ground by reference to the specific fluvial
characteristics set forth in the definitions of these terms. These terms also refer to overlay zoning
districts whose boundaries correspond to the actual physical location of floodways and floodplains as
shown on FEMA's flood insurance rate map (FIRM) and should be shown on the map identified in
Section 20.92 93.970, Appendix A (Shoreline Master Plan). (These overlay districts thus differ from
other zoning districts whose boundaries are established solely according to planning or policy, rather
than physical, criteria.) Therefore, the administrator is authorized to make necessary interpretations
as to the exact location of the boundaries of floodways or floodplains if there appears to be a conflict
between a mapped boundary and actual field conditions. Such interpretations, like other decisions of
the administrator, may be appealed pursuant to Section 20.20.010 (Appeals).
(b) As used in this chapter the term riparian habitat zone (RHZ) is identified on the approved RHZ map.
The RHZ is an overlay zone that encompasses lands as defined above on either side of all streams,
and for all other watercourse including off channel areas within the special flood hazard areas. The
RHZ is a no new disturbance zone, other than for activities that will not adversely affect the existing
habitat function. Any property or portion thereof that lies within the RHZ is subject to the restrictions of
the RHZ, as well as any zoning restriction that apply to the parcel in the underlying zoning. Unless
shown otherwise the RHZ on a channel migration zone is fifty feet. Other areas not identified on the
RHZ, but are located in the floodplain areas will be subject to the Shoreline Master Plan Critical Areas
Appendix B.
(c) When updating the maps the city must consider future conditions and the cumulative effect from the
future land-use changes.
(d) When updating the maps the city must consider identifying and evaluating the risk of flooding behind
one hundred-year levees within the city jurisdiction based on future conditions and cumulative effects.
(e) When evaluating risk it may be determined that an individual project will conduct an ESA consultation
with the services.

the ten-, fifty-, and one hundred-year floods, where such data are available, and
(F) The applicant must record a notice on the title that the property contains land within the RHZ
and/or one hundred-year floodplain before a permit may be issued, and
(G) Any improvements or repairs to existing structures that result in a greater than ten percent
increase of the structure footprint must mitigate for any adverse effects, and
(H) Removal of native vegetation must leave sixty-five percent of the surface area of the portion
of the property in the floodplain with native vegetation in an undeveloped state, and
(I) Development in the protected area (floodway, RHZ, and CMZ plus 50 feet) is prohibited

(J) Development outside the protected area must mitigate for adverse indirect effects on
stormwater, riparian vegetation, bank stability, channel migration, hyporheic zone, wetland
and large woody debris functions.
(2) Any development outside the Protected Area must mitigate for adverse effects, both direct and
indirect on functions such that equivalent or better salmon habitat protection is provided for:
(A) Stormwater: Reduce flood volumes and stormwater runoff from new development by ensuring
that increased flood volumes of stormwater reach the river at the same frequency, timing and
duration as historic runoff. LID is required to be incorporated as described in Chapter 20.64.140

in these zones range from one to three feet above ground where a clearly defined channel does not exist,
or where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is
usually characterized as sheet flow. In these areas, the following provisions apply:
(1) New construction and substantial improvements of residential structures and manufactured
homes within AO Zones shall have the lowest floor (including basement) elevated above the
highest adjacent grade to the structure, one foot or more above the depth number specified in
feet on the community's FIRM (at least two feet above the highest adjacent grade to the structure

within the SFHA shall have the lowest floor elevated three feet or to the height of the five hundred-year
flood, whichever is higher. Access to and from the critical facility should also be protected to the height
utilized above. Floodproofing and sealing measures must be taken to ensure that toxic substances will not
be displaced by or released into floodwaters. Access routes elevated to or above the level of the base flood
elevation shall be provided to all critical facilities to the extent possible.
(Ord. 1309 § 5(part), 2003)
20.64.250 240 ‐ Additional duties of administrator related to flood insurance and flood control.
The administrator shall:
(1) For the purpose of the determination of applicable flood insurance risk premium rates within zone
A on the city's flood insurance rate map provided by the U.S. Federal Emergency Management
Agency:
(A) Obtain and record the elevation (in relation to mean sea level) of the lowest floor (including
basement) of all new or substantially improved structures including to which level it was
floodproofed; and
Formatted: Font: (Default) Arial, 10 pt

Page 18
Formatted: Centered
(B) Obtain, for all structures that have been floodproofed (whether or not such structures contain
a basement) the elevation (in relation to mean sea level in the FEMA datum) to which the
structure was floodproofed; and
(C) Maintain the floodproofing certifications found in others sections of this chapter; and
(D) For development that occurs outside of the protected area tThe city will track projects which
have been issued floodplain development permits, including effects to flood storage and fish
habitat and mitigation provided.
(E) Maintain a record of all such information for public inspection.
(2) Notify, in riverine situations, adjacent communities, the U.S. Army Corps of Engineers, the
Washington State Department of Fish and Wildlife, and any effected diking or drainage districts
prior to any alteration or relocation of a watercourse, and submit copies of such notification to the
Federal Insurance Administrator.
(3) Ensure that the flood-carrying capacity within the altered or relocated portion of any watercourse
is maintained and within the same sub-basin so carrying capacity is not diminished.
(4) Maintain the records of all appeal actions and report any variances to the Federal Insurance
Administration upon request.
(Ord. No. 1365, § 23, 6-13-2005; Ord. 1309 § 5(part), 2003)
(Ord. No. 2011-030, § 13, 12-5-2011)
20.64.260 250 ‐ Variances from requirements.
(a) Generally, the only condition under which a variance from the elevation standard may be issued is for
new construction and substantial improvements to be erected on a lot of one-half acre or less in size
contiguous to and surrounded by lots with existing structures constructed below the base flood level,
providing items (1—11) in subsection (i) have been fully considered. As the lot size increases, the
technical justification required for issuing the variance increases.
(b) Variances may be issued for the reconstruction, rehabilitation, or restoration of structures listed on the
National Register of Historic Places or the state inventory of historic places, without regard to the
procedures set forth in this section.
(c) Variances shall not be issued within a designated floodway if any increase in flood levels during the
base flood discharge would result, or the development may eventually require additional structural
flood protection.
(d) Variances shall only be issued upon a determination that the variance is the minimum necessary,
considering the flood hazard, to afford relief.
(e) Variances shall only be issued upon:
(1) A showing of good and sufficient cause;
(2) The submittal, review and approval of a biological assessment;
(3) A determination that failure to grant the variance would result in exceptional hardship to the
applicant;
(4) A determination that the granting of a variance will not result in increased flood heights, additional
threats to public safety, extraordinary public expense, create nuisances, cause fraud on or
victimization of the public, or conflict with existing local laws or ordinances.
(f) Variances as interpreted in the national flood insurance program are based on the general zoning law
principle that they pertain to a physical piece of property; they are not personal in nature and do not
Title 20, Chapter 20.64 Rewrite 3/15/16, edited 5/18/16
Page 19
Formatted: Centered
pertain to the structure, its inhabitants, economic or financial circumstances. They primarily address
small lots in densely populated residential neighborhoods. As such, variances from the flood elevations
should be quite rare.
(g) Variances may be issued for nonresidential buildings in very limited circumstances to allow a lesser
degree of floodproofing than watertight or dry-floodproofing, where it can be determined that such
action will have low damage potential, complies with all other variance criteria except subsection (i)1,
and otherwise complies with Subsection 20.64.170(a) General Standards), Subsection 20.64.170(c),
and Section 20.64.230 (Utility Systems in Floodways and Floodplains).
(h) Any applicant to whom a variance is granted is hereby notified that the structure will be permitted to
be built with a lowest floor elevation below the base flood elevation and that the cost of flood insurance
will be commensurate with the increased risk resulting from the reduced lowest floor elevation.
(i) In granting a variance, in addition to the findings of Section 20.20.030 (Variances), the decision-maker
shall consider and make findings concerning all technical evaluations, all relevant factors, standards
specified in other sections of this chapter, and (including the degree to which the applicant proposes
to mitigated impacts to) the following:
(1) The danger that materials may be swept onto other lands to the injury of others;
(2) The danger to life and property due to flooding or erosion damage;
(3) The impact to ESA listed species;
(4) The susceptibility of the proposed facility and its contents to flood damage and the effect of such
damage on the individual owner;
(5) The importance of the services provided by the proposed facility to the community;
(6) The necessity to the facility of a waterfront location, where applicable;
(7) The availability of alternative locations for the proposed use which are not subject to flooding or
erosion damage;
(8) The compatibility of the proposed use with existing and anticipated development;
(9) The relationship of the proposed use to the comprehensive plan and floodplain management
program for that area;
(10) The safety of access to the property in times of flood for ordinary and emergency vehicles;
(11) The expected heights, velocity, duration, rate of rise, debris and sediment transport of the flood
waters and the effects of wave action, if applicable, expected at the site; and,
(12) The costs of providing governmental services during and after flood conditions, including
maintenance and repair of public utilities and facilities such as sewer, gas, electrical, and water
systems, and streets and bridges.
(j) Upon consideration of the factors of subsection (b) and the purposes of this chapter, the decision-
maker may attach such conditions to the granting of a waiver, as it deems necessary to further the
purposes of this chapter.

The legislature of the state of Washington has delegated the responsibility to local
governmental units to adopt regulations designed to promote the public health, safety, and
general welfare of its citizenry. Therefore, the city of Arlington does ordain as follows:
20.64.020 - Findings of fact.
(a) The Special Flood Hazard Areas of Arlington encompass a very small area (0.02%) of
the developable lands within the corporate limits of the city. These areas are subject to
periodic inundation of floodwaters due to storm surges and runoff, which may result in
property damage, public safety, disruption of commerce, and other consequences.
(b) The National Flood Insurance Program is adopted by the City of Arlington, which aims
to reduce the impact of flooding on private and public structures. It does so by providing
affordable insurance to property owners and by encouraging communities to adopt and
enforce floodplain management regulations. The efforts help mitigate the effects of
flooding on new and improved structures.
(c) On September 22, 2008, the National Marine Fisheries Service (NMFS) issued a
Biological Opinion that required changes to the implementation of the National Flood
Insurance Program in order to meet the requirements of the Endangered Species Act
(ESA) in the Puget Sound Watershed. The City of Arlington enacted regulations that
allow development that meets the criteria specified in the Biological Opinion as a “Door
2” Community.
20.64.030 - Statement of purpose.
It is the purpose of this chapter to promote the public health, safety, and general welfare,
and to minimize public and private losses due to flood conditions in specific areas by
provisions designed:
(1) To protect human life and health;
ORDINANCE No. 2016-XXX 3
(2) To manage development in a manner reducing impacts to floodplain processes;
(3) To minimize expenditure of public money and costly flood control projects;
(4) To minimize the need for rescue and relief efforts associated with flooding and
generally undertaken at the expense of the general public;
(5) To minimize prolonged business interruptions;
(6) To minimize damage to public facilities and utilities such as water and gas mains,
electric, telephone and sewer lines, streets, and bridges located in areas of special
flood hazard;
(7) To help maintain a stable tax base by providing for the sound use and development
of areas of special flood hazard so as to minimize future flood blight areas;
(8) To ensure that potential buyers are notified that property is in an area of special flood
hazard; and,
(9) To ensure that those who occupy the areas of special flood hazard assume
responsibility for their actions.
20.64.040 - Methods of reducing flood losses.
In order to accomplish its purposes, this chapter includes methods and provisions for:
(1) Regulating development in Special Flood Hazard Areas (SFHA);
(2) Requiring that all development and land use activity be protected against flood
damage at the time of initial construction;
(3) Regulating filling, grading, dredging, and other development which may have an
adverse impact on flood waters ; and
(4) Preventing or regulating the construction of flood barriers that will unnaturally divert
floodwaters or may increase flood hazards in other areas.

building commences, whether or not that alteration affects the external dimensions
of the structure.
The term does not, however, include either:
(3) Any project for improvement of a structure to correct existing violations of state or
local health, sanitary, or safety code specifications which have been identified by the
local code enforcement official and which are the minimum necessary to assure safe
living conditions, or
(4) Any alteration of a "historic structure," provided that the alteration would not
preclude the structure's continued designation as a "historic structure."
"Variance" means a grant of relief from the requirements of this chapter that permits
construction in a manner that would otherwise be prohibited by this chapter.
"Water dependent" means a structure for commerce or industry that cannot exist in any
other location and is dependent on the water because of the intrinsic nature of its operations.
20.64.060 - Basis for establishing the areas of special flood hazard.
(a) The areas of special flood hazard identified by the Federal Insurance Administration in a
scientific and engineering report entitled "The Flood Insurance Study for Snohomish
County and Incorporated Areas" (in which the city is incorporated) dated September 16,
2005, or as amended, with an accompanying flood insurance rate map (FIRM), as
amended, are hereby adopted by reference and declared to be a part of this section. The
flood insurance study and the FIRM are on file at Arlington City Hall, 238 North
Olympic, Arlington, Washington. The best available information for flood hazard area
identification as outlined in subsection (b) shall be the basis for regulation until a new
FIRM is issued which incorporates the data utilized under subsection (b).
(b) When base flood elevation data has not been provided (A and V Zones) in accordance
with subsection (a), the administrator shall use any base flood elevation and floodway
data available from a federal, state or other source, in order to comply with Section
20.64.170 (Specific Standards for Zones A1-30, AH, and AE) and Section 20.64.180
(Specific Standards for Designated Regulatory Floodways).
(c) If such data are not already available, the administrator may rely on a licensed surveyor
to provide such information as necessary to reasonably ascertain said zones.
20.64.070 - 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.
20.64.080 - Interpretation.
In the interpretation and application of this chapter, all provisions shall be:
(1) Considered as minimum requirements;
(2) Liberally construed in favor of the governing body; and,
(3) Deemed neither to limit nor repeal any other powers granted under State statutes.
ORDINANCE No. 2016-XXX 7
20.64.090 - 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 City of Arlington, 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.
Part II – Development Regulations
20.64.100 - Supplementary information required with a permit application.
In addition to the standard information required on a permit application, the following
information is also required for any permits proposing development within a floodway or
floodplain, watercourse alteration or relocation:
(1) Elevation in relation to mean sea level, of the lowest floor (including basement) of
all structures;
(2) Elevation in relation to mean sea level to which any structure has been floodproofed;
(3) Elevation Certification by a registered professional engineer or architect.
(4) Notify adjacent communities and the Department of Ecology prior to any alteration
or relocation of a watercourse, and submit evidence of such notification to the Federal
Insurance Administration.
(5) Require that maintenance is provided within the altered or relocated portion of said
watercourse so that the flood carrying capacity is not diminished.
20.64.110 - Location of boundaries of floodplain and floodway districts.
(a) As used in this chapter, the terms floodplain and floodway refer in the first instance to
certain areas whose boundaries are determined and can be located on the ground by
reference to the specific fluvial characteristics set forth in the definitions of these terms.
These terms also refer to overlay zoning districts whose boundaries correspond to the
actual physical location of floodways and floodplains as shown on FEMA's flood
insurance rate map (FIRM) and should be shown on the map identified in the City’s
adopted Shoreline Master Plan. (These overlay districts thus differ from other zoning
districts whose boundaries are established solely according to planning or policy, rather
than physical, criteria.) Therefore, the administrator is authorized to make necessary
interpretations as to the exact location of the boundaries of floodways or floodplains if
there appears to be a conflict between a mapped boundary and actual field conditions.
Such interpretations, like other decisions of the administrator, may be appealed pursuant
to Section 20.20.010 (Appeals).
(b) As used in this chapter the term riparian habitat zone (RHZ) is identified on the approved
RHZ map. The RHZ is an overlay zone that encompasses lands as defined above on either
side of all streams, and for all other watercourse including off channel areas within the
special flood hazard areas. The RHZ is a no new disturbance zone, other than for
activities that will not adversely affect the existing habitat function. Any property or
portion thereof that lies within the RHZ is subject to the restrictions of the RHZ, as well
ORDINANCE No. 2016-XXX 8
as any zoning restriction that apply to the parcel in the underlying zoning. Unless shown
otherwise the RHZ on a channel migration zone is fifty feet.
(c) When updating the maps the city must consider future conditions and the cumulative
effect from the future land-use changes.
(d) When updating the maps the city must consider identifying and evaluating the risk of
flooding behind one hundred-year levees within the city jurisdiction based on future
conditions and cumulative effects.
20.64.120 - Setbacks from streams RHZ within the floodplain.

F-> 5 feet wide and marine shorelines 150 feet
F - < 5 feet wide and lakes 150 feet
N – perennial and seasonal streams 150 – 225 feet2
2 Depending on slope stability
1 Channel Migration Zone (CMZ) plus 50 feet
(a) Communities must use the most restrictive data available for the CMZ, Floodway,
future conditions, and RHZ’s.
20.64.130 - Artificial obstructions within floodways prohibited.
(a) No artificial obstruction may be located within any floodway, except as provided in
Section 20.64.140 (Permissible Uses Within Floodways).
(b) For purposes of this section, an artificial obstruction is any obstruction, other than a
natural obstruction, that is capable of reducing the flood-carrying capacity of a stream or
may accumulate debris and thereby reduce the flood-carrying capacity of a stream. A
natural obstruction includes any rock, tree, gravel, or analogous natural matter that is an
obstruction and has been located within the floodway by a non-human cause.
20.64.140 - Permissible uses within floodways.
(a) Notwithstanding Chapter 20.40 (Permissible Uses) of this Title, no permit to make use of
land within a floodway may be issued unless the proposed use is listed as permissible in
the Table of Permissible Uses, Chapter 20.93 (Critical Areas Ordinance), and in the
following list:
(1) General habitat restoration, farming, pasture, outdoor plant nurseries, horticulture,
forestry, wildlife sanctuary, game farm, and other similar agricultural, wildlife, and
related uses.
(2) Ground-level loading areas, parking areas, boat launch, rotary aircraft ports, and
other similar ground-level area uses.
ORDINANCE No. 2016-XXX 9
(3) Lawns, gardens, play areas, and other similar uses.
(4) Golf courses, tennis courts, driving ranges, archery ranges, picnic grounds, parks,
hiking or horseback-riding trails, open space, and other similar private and public
recreational uses.
(b) General development standards to be followed in special flood hazard area include:
(1) If a lot has a buildable site out of the special flood hazard area, all new structures
shall be located there, when feasible. If the lot is fully in the floodplain, structures
must be located to have the least impact on salmon.
a. All structures must be set back at least 15 feet from the protected area and sited as
close to the SFHA boundary as possible.
(2) Stormwater and drainage features shall incorporate low impact development
techniques that mimic pre-development hydrologic conditions, when technically
feasible.
(3) Creation of new impervious surfaces shall not exceed ten percent of the surface area
of the portion of the lot in the floodplain unless mitigation is provided.
(4) Uses that are not permitted in the protected area unless shown not to adversely affect
water quality, habitat, and large woody debris include; septic tanks and drain fields,
dumping of any materials, hazardous or sanitary waste landfills: receiving area for
toxic or hazardous waste or other contaminants.
(5) a. The proposed action must be designed and located so that new structural flood
protection is not needed.
b. All bank stabilization measures requiring armoring of the streambank or
shoreline shall utilize bioengineering per the Integrated Streambank Protection
Guidelines 2003 (for riverine shorelines) or the State Shorelines Guidelines on
bank stabilization 2003 (for estuarine and marine shorelines).
(6) In an SFHA outside the Protected Area, zoning is required to maintain a low density
of flood plain development. Concepts of cluster development, density transfer,
credits and bonuses, planned unit development, and transfer of development rights
shall be employed wherever possible.
20.64.150 - Construction within floodways and floodplains restricted.
Any development occurring in the floodway or floodplain will require the issuance of a
"flood hazard permit". A development permit shall be obtained before construction or
development begins within any area of special flood hazard area. The permit shall be for all
structures including manufactured homes, and for all development including fill and other
activities as set forth in this chapter.
(1) No land use or building permit may be issued for any development within a
floodplain until the permit-issuing authority has reviewed the plans for any such
development to assure that:
(A) The proposed development is consistent with the need to minimize flood
damage, and
(B) All public utilities and facilities such as sewer, gas, electrical, and water systems
are located and constructed to minimize or eliminate flood damage, and

(D) All necessary permits have been received from those agencies from which
approval is required by federal or state law, and
(E) The application for a permit to develop in the affected area must include the
elevations of the ten-, fifty-, and one hundred-year floods, where such data are
available, and
(F) The applicant must record a notice on the title that the property contains land
within the RHZ and/or one hundred-year floodplain before a permit may be
issued, and
(G) Any improvements or repairs to existing structures that result in a greater than
ten percent increase of the structure footprint must mitigate for any adverse
effects, and
(H) Removal of native vegetation must leave sixty-five percent of the surface area
of the portion of the property in the floodplain in an undeveloped state, and
(I) Development in the protected area (floodway, RHZ, and CMZ plus 50 feet) is
prohibited unless it is demonstrated that any proposed development in the area
does not adversely affect water quality, water quantity, flood volumes, flood
velocities, spawning substrate, and/or floodplain refugia for listed salmonids.
No mitigation is allowed within the protected area. However, project design
elements to avoid any adverse effects may be allowed.
(2) Any development outside the Protected Area must mitigate for adverse effects, both
direct and indirect on functions such that equivalent or better salmon habitat
protection is provided for:
(A) Stormwater: Reduce flood volumes and stormwater runoff from new
development by ensuring that increased flood volumes of stormwater reach the river
at the same frequency, timing and duration as historic runoff. Low impact
development is required to be incorporated as described in Chapter 20.64.140(b)(2).
(B) Riparian vegetation: maintain or replace riparian function by providing
equivalent area, diversity, and function of riparian vegetation as currently exists on
the site. Riparian retention requirements are outlined in Chapter 20.64.150(1)(H).

inch bolts six feet on center with a minimum of two per side shall be required.
If over-the-top ties are used, a minimum of two ties with a force adequate to
secure the building is required.
(6) No new nonresidential building may be constructed and no substantial improvements
of a nonresidential building may take place within any floodplain unless the lowest
floor (including basement) of the building or improvement is elevated or
floodproofed one foot or more above base flood elevation (BFE).
(7) For purposes of this section, "substantial improvement" means for a building
constructed prior to the effective date of this title, any repair, reconstruction, or
improvement of a building the cost of which equals or exceeds fifty percent of the
market value of the structure either:
(A) Before the improvement or repair is started or
(B) If the structure has been damaged and is being restored, before the damage
occurred.
"Substantial improvement" occurs when the first alteration on any wall, ceiling,
floor, or other structural part of the building commences, whether or not that
alteration affects the external dimensions of the building. The term does not,
however, include either:
(A) Any project for improvement of a structure to comply with existing state or local
health, sanitary, or safety code specifications that are solely necessary to insure
safe living conditions, or
(B) Any alteration of a building listed on the National Register of Historic Places or
a State Inventory of Historic Places.
(8) No land use or building permit may be issued for any development within a
floodplain until the permit-issuing authority has reviewed the plans to assure that any
new construction or substantial improvements shall be:
(A) Designed (or modified) and adequately anchored to prevent flotation collapse,
or lateral movement of the structure.
(B) Constructed with materials and utility equipment resistant to flood damage.
(C) Constructed by methods and practices that minimize flood damage.

20.64.180 - Specific standards for designated regulatory floodways.
Located within areas of special flood hazard established in Section 20.64.060 (Basis for
Establishing the Areas of Special Flood Hazard) are areas designated as floodways. Since the
floodway is an extremely hazardous area due to the velocity of floodwaters that carry debris,
potential projectiles, and erosion potential, the following provisions apply:
(1) Prohibit encroachments, including fill, new construction, substantial improvements,
and other development unless certification by a registered professional engineer is
provided demonstrating through hydrologic and hydraulic analyses performed in
accordance with standard engineering practice that the proposed encroachment
would not result in any increase in flood levels during the occurrence of the base
flood discharge.
(2) Construction or reconstruction of residential structures is prohibited within
designated floodways, except for (i) repairs, reconstruction, or improvements to a
structure which do not increase the ground floor area; and (ii) repairs, reconstruction
or improvements to a structure, the cost of which does not exceed fifty percent of the
market value of the structure either, (A) before the repair, or reconstruction is started,
or (B) if the structure has been damaged, and is being restored, before the damage
occurred. Any project for improvement of a structure to correct existing violations
of state or local health, sanitary, or safety code specifications which have been
identified by the local code enforcement official and which are the minimum
necessary to assure safe living conditions or to structures identified as historic places
shall not be included in the fifty percent.
ORDINANCE No. 2016-XXX 15
(3) If Subsection 1 is satisfied, all new construction and substantial improvements shall
comply with all applicable flood hazard reduction provisions of Section 20.64.180
through Section 240.
20.64.190 - Specific standards for shallow flooding areas (AO Zones).
Shallow flooding areas appear on FIRMs as AO Zones with depth designations. The base
flood depths in these zones range from one to three feet above ground where a clearly defined
channel does not exist, or where the path of flooding is unpredictable and where velocity flow
may be evident. Such flooding is usually characterized as sheet flow. In these areas, the
following provisions apply:
(1) New construction and substantial improvements of residential structures and
manufactured homes within AO Zones shall have the lowest floor (including
basement) elevated above the highest adjacent grade to the structure, one foot or
more above the depth number specified in feet on the community's FIRM (at least
two feet above the highest adjacent grade to the structure if no depth number is
specified).
(2) New construction and substantial improvements of nonresidential structures within
AO Zones shall either:
(A) Have the lowest floor (including basement) elevated above the highest adjacent
grade of the building site, one foot or more above the depth number specified on
the FIRM (at least two feet if no depth number is specified); or
(B) Together with attendant utility and sanitary facilities, be completely flood
proofed to or above that level so that any space below that level is watertight
with walls substantially impermeable to the passage of water and with structural
components having the capability of resisting hydrostatic and hydrodynamic
loads and effects of buoyancy. If this method is used, a registered professional
engineer or architect as in Subsection 20.64.170 (Specific Standards for Zones
A1-30, AH, and AE) shall certify compliance.
(3) Require adequate drainage paths around structures on slopes to guide floodwaters
around and away from proposed structures.
(4) Recreational vehicles placed on sites within AO Zones on the community's FIRM
either:
(A) Be on the site for fewer than one hundred eighty consecutive days,
(B) Be fully licensed and ready for highway use, on its wheels or jacking system, is
attached to the site only by quick disconnect type utilities and security devices,
and has no permanently attached additions; or
(C) Meet the requirements of Subsections 1 and 3 above and the anchoring
requirements for manufactured homes (Subsection 20.64.160(1), General
Standards).
20.64.210 AE and A1-30 Zones with Base Flood Elevations but No Floodways.
In areas with base flood elevations (but where a regulatory floodway has not been
designated), no new construction, substantial improvements, or other development (including
fill) shall be permitted within Zones A1-30 and AE on the community's FIRM, unless it is
demonstrated that the cumulative effect of the proposed development, when combined with
ORDINANCE No. 2016-XXX 16
all other existing and anticipated development, will not increase the water surface elevation
of the base flood more than one foot at any point within the community.
20.64. 215 - Special provisions for subdivisions.
(a) All subdivision proposals shall be consistent with the need to minimize flood damage.
(b) All subdivision proposals shall have public utilities and facilities, such as sewer, gas,
electrical, and water systems located and constructed to minimize or eliminate flood
damage.
(c) All subdivision proposals shall have adequate drainage provided to reduce exposure to
flood damage.
(d) Where base flood elevation data has not been provided or is not available from another
authoritative source, it shall be generated for subdivision proposals and other proposed
developments that contain at least fifty lots or five acres (whichever is less).
(e) All subdivisions are subject to use and construction restrictions contained in Section
20.64.130 (Artificial Obstructions Within Floodways Prohibited), Section 20.64.140
(Permissible Uses Within Floodways), Section 20.64.150 (Construction Within
Floodways and Floodplains Restricted), and Section 20.64.220 (Utility Systems in
Floodways and Floodplains) if any portion of the land to be subdivided lies within a
floodway or floodplain.
(f) Final plat approval for any subdivision containing land that lies within a floodway or
floodplain may not be given unless the plat shows the boundary of the floodway or
floodplain and contains in clearly discernible print the following statement: "Use of land
within a floodway or floodplain is substantially restricted by Title 20, Chapter 20.64 of
the Arlington Municipal Code."
(g) Subject to the following sentence, a conditional use permit or final plat approval for any
subdivision may not be given if:
(1) The land to be subdivided lies within a zone where residential uses are permissible
and it reasonably appears that the subdivision is designed to create residential
building lots, and
(2) Any portion of one or more of the proposed lots lies within a floodway or floodplain,
and
(3) It reasonably appears that one or more lots described in Subdivisions (1) and (2) of
this subsection could not practicably be used as a residential building site because of
the restrictions set forth in Section 20.64.150 (Construction Within Floodways and
Floodplains Restricted), Section 20.64.160 (General Standards), and Section
20.64.170 (Specific Standards for Zones A1-30, AH, and AE).
20.64.220 - Utility systems in floodways and floodplains.
Whenever any portion of a proposed development is located within a floodway or
floodplain, the agency or agencies responsible for certifying to the city the adequacy of the
utility systems for the development (as set forth in Chapter 20.60) shall be informed by the
developer that a specified area within the development lies within a floodway or floodplain.
Thereafter, said agency shall certify, prior to approval of the proposed system, that:
(1) All new and replacement water supply systems are designed to minimize or eliminate
infiltration of flood waters into the systems;
ORDINANCE No. 2016-XXX 17
(2) Any proposed water wells are located on high ground that is not in the floodway
(WAC 173-160-171);
(3) New and replacement sanitary sewage systems are designed to minimize or eliminate
infiltration of flood waters into the systems and discharges from the systems into
flood waters; and,
(4) On-site waste disposal systems are located to avoid impairment to them or
contamination from them during flooding; and
(5) All new utilities would be located so as to prevent water from entering or
accumulating within the components during conditions of flooding.
20.64.230 - Critical facility.
Construction of new critical facilities shall be, to the extent possible, located outside the
limits of the Special Flood Hazard Area (SFHA) (one hundred-year floodplain). Construction
of new critical facilities shall be permissible within the SFHA if no feasible alternative site is
available. Critical facilities constructed within the SFHA shall have the lowest floor elevated
three feet or to the height of the five hundred-year flood, whichever is higher. Access to and
from the critical facility should also be protected to the height utilized above. Floodproofing
and sealing measures must be taken to ensure that toxic substances will not be displaced by
or released into floodwaters. Access routes elevated to or above the level of the base flood
elevation shall be provided to all critical facilities to the extent possible.
20.64. 240 - Additional duties of administrator related to flood insurance and flood control.
The administrator shall:
(1) For the purpose of the determination of applicable flood insurance risk premium rates
within zone A on the city's flood insurance rate map provided by the U.S. Federal
Emergency Management Agency:
(A) Obtain and record the elevation (in relation to mean sea level) of the lowest floor
(including basement) of all new or substantially improved structures including
to which level it was floodproofed; and
(B) Obtain, for all structures that have been floodproofed (whether or not such
structures contain a basement) the elevation (in relation to mean sea level in the
FEMA datum) to which the structure was floodproofed; and
(C) Maintain the floodproofing certifications found in others sections of this chapter;
and
(D) The city will track projects which have been issued floodplain development
permits, including effects to flood storage and fish habitat and mitigation
provided.
(E) Maintain a record of all such information for public inspection.
(2) Notify, in riverine situations, adjacent communities, the U.S. Army Corps of
Engineers, the Washington State Department of Fish and Wildlife, and any effected
diking or drainage districts prior to any alteration or relocation of a watercourse, and
submit copies of such notification to the Federal Insurance Administrator.
(3) Ensure that the flood-carrying capacity within the altered or relocated portion of any
watercourse is maintained and within the same sub-basin so carrying capacity is not
diminished.
ORDINANCE No. 2016-XXX 18
(4) Maintain the records of all appeal actions and report any variances to the Federal
Insurance Administration upon request.
20.64.250 - Variances from requirements.
(a) Generally, the only condition under which a variance from the elevation standard may be
issued is for new construction and substantial improvements to be erected on a lot of one-
half acre or less in size contiguous to and surrounded by lots with existing structures
constructed below the base flood level, providing items (1—11) in subsection (i), below,
have been fully considered. As the lot size increases, the technical justification required
for issuing the variance increases.
(b) Variances may be issued for the reconstruction, rehabilitation, or restoration of structures
listed on the National Register of Historic Places or the state inventory of historic places,
without regard to the procedures set forth in this section.
(c) Variances shall not be issued within a designated floodway if any increase in flood levels
during the base flood discharge would result, or the development may eventually require
additional structural flood protection.
(d) Variances shall only be issued upon a determination that the variance is the minimum
necessary, considering the flood hazard, to afford relief.
(e) Variances shall only be issued upon:
(1) A showing of good and sufficient cause;
(2) The submittal, review and approval of a biological assessment;
(3) A determination that failure to grant the variance would result in exceptional
hardship to the applicant;
(4) A determination that the granting of a variance will not result in increased flood
heights, additional threats to public safety, extraordinary public expense, create
nuisances, cause fraud on or victimization of the public, or conflict with existing
local laws or ordinances.
(f) Variances as interpreted in the national flood insurance program are based on the general
zoning law principle that they pertain to a physical piece of property; they are not personal
in nature and do not pertain to the structure, its inhabitants, economic or financial
circumstances. They primarily address small lots in densely populated residential
neighborhoods. As such, variances from the flood elevations should be quite rare.
(g) Variances may be issued for nonresidential buildings in very limited circumstances to
allow a lesser degree of floodproofing than watertight or dry-floodproofing, where it can
be determined that such action will have low damage potential, complies with all other
variance criteria except subsection (i)1, and otherwise complies with Subsection
20.64.160(a) General Standards), Subsection 20.64.170(c), and Section 20.64.220
(Utility Systems in Floodways and Floodplains).
(h) Any applicant to whom a variance is granted is hereby notified that the structure will be
permitted to be built with a lowest floor elevation below the base flood elevation and that
the cost of flood insurance will be commensurate with the increased risk resulting from
the reduced lowest floor elevation.
(i) In granting a variance, in addition to the findings of Section 20.20.030 (Variances), the
decision-maker shall consider and make findings concerning all technical evaluations, all
relevant factors, standards specified in other sections of this chapter, and (including the
degree to which the applicant proposes to mitigated impacts to) the following:
ORDINANCE No. 2016-XXX 19
(1) The danger that materials may be swept onto other lands to the injury of others;
(2) The danger to life and property due to flooding or erosion damage;
(3) The impact to ESA listed species;
(4) The susceptibility of the proposed facility and its contents to flood damage and the
effect of such damage on the individual owner;
(5) The importance of the services provided by the proposed facility to the community;
(6) The necessity to the facility of a waterfront location, where applicable;
(7) The availability of alternative locations for the proposed use which are not subject to
flooding or erosion damage;
(8) The compatibility of the proposed use with existing and anticipated development;
(9) The relationship of the proposed use to the comprehensive plan and floodplain
management program for that area;
(10) The safety of access to the property in times of flood for ordinary and emergency
vehicles;
(11) The expected heights, velocity, duration, rate of rise, debris and sediment transport
of the flood waters and the effects of wave action, if applicable, expected at the site;
and,
(12) The costs of providing governmental services during and after flood conditions,
including maintenance and repair of public utilities and facilities such as sewer, gas,
electrical, and water systems, and streets and bridges.
(j) Upon consideration of the factors of subsection (b) and the purposes of this chapter, the
decision-maker may attach such conditions to the granting of a waiver, as it deems
necessary to further the purposes of this chapter.
Section 3. Effective Date. A summary of this Ordinance consisting of its title
shall be published in the official newspaper of the City, and shall take effect and be in full
force five (5) days of the date of publication.
Section 4. Severability. If any provision, section, or part of this ordinance shall be
adjudged to be invalid or unconstitutional, such adjudication shall not affect the validity of
the ordinance as a whole or any section, provision or part thereof not adjudged invalid or
unconstitutional.
Section 5. Copy to Commerce Department. Pursuant to RCW
36.70A.106(3), the City Clerk is directed to send a copy of this ordinance to the State
Department of Commerce for its files within ten (10) days after adoption of this
ordinance.

DESCRIPTION:
Revisions to Chapter 20.93 to comply with the Department of Ecology’s updated
wetland Delineation Manual and 2014 Washington State Rating System regarding our
Critical Areas Ordinance. Repeal of Chapter 20.88 making Chapter 20.93 our CAO,
stand-alone document. Several meetings/discussions took place with ECY staff
during the rewrite, several meetings (workshops) held with the Planning Commission,
and a Noticed Public Hearing was held on July 7, 2016. The Planning Commission’s
Findings of Facts will be provided as part of this ordinance.
HISTORY:
The Arlington Municipal Code currently contains two Critical Area Ordinances,
Chapter 20.93 and Chapter 20.88. It was believed that Chapter 20.93 pertained to
critical areas as part of the Shoreline Master Program and Frequently Flooded Areas
and that 20.88 pertained to all other areas of the city. This caused confusion with
developer’s as they were unsure what Chapter to design to. The City was required to
conduct a periodic review of its Critical Areas Ordinance(s), per GMA, 30.70A RCW in
June 2015. Staff consulted with Department of Ecology, Donna Bunten and Doug
Gresham regarding both 20.93 & 20.88. It was recommended by ECY staff that 20.93
be amended and 20.88 be deleted so that our CAO is a stand-alone chapter.

Chapter 20.93 ‐ ENVIRONMENTALLY CRITICAL AREAS Critical Area Ordinance
Sections:
Part I. ‐ Purpose and Intent
20.93.010 ‐ Purpose and intent.
This chapter establishes regulations for the protection of environmentally critical areas (ECAs) within
the city's shoreline jurisdiction, including critical areas, natural resource lands, and protective buffers. While
it is intended that this chapter fulfill the mandates of the Washington State Shoreline Growth Management
Act, that is not its sole purpose: Its primary purpose is to fulfill the legislative intent of the city of Arlington,
which is to protect the public health, safety, and welfare of the citizens of Arlington by providing for the long-
term preservation of natural systems and their functions. This is to be accomplished by establishing
prohibitions, mitigation requirements, and minimum standards for the use and development of properties
that contain or adjoin environmentally critical areas. Additionally, this chapter is intended to:
(1) If at all possible, avoid impacts to environmentally critical areas. If this is not practicable, then:
(A) Minimize or limit the degree or magnitude of actions and their implementation by using
appropriate technology or by taking affirmative steps to avoid or reduce impacts.
(B) Mitigate any impacts by repairing, rehabilitating, or restoring the affected environment.
(C) Reduce or eliminate any impacts over time by preservation and maintenance operations
during the life of the action.
(D) Compensate for unavoidable impacts by replacing, enhancing or providing substitute

directly and in the immediate vicinity of the impact. However, alternative compensatory mitigation within the
watershed sub-basin that addresses limiting factors or identified critical needs for shoreline resource
conservation based on watershed or comprehensive resource management plans applicable to the area of
impact may be authorized. If there are no previously identified mitigation opportunities in the impacted sub-
basin identified in local watershed or comprehensive plans the applicant will use a watershed approach in
selecting mitigation sites utilizing Selecting Wetland Mitigation Sites Using a Watershed Approach (Western
Washington) (Publication #09-06-32).
"Constructed stormwater wetland". A stormwater management system that is designed and built to
function similar to the naturally occurring wetland including native trees and shrubs allowed to grow to

20.93.230 ‐ Compliance.
All land uses or development applications shall be reviewed to determine whether an environmentally
critical area exists on the property for which the application is filed, what the action's impacts to any existing
environmentally critical area would be, and what actions are required for compliance with this chapter. No
construction activity, including land clearing or grading, shall be permitted until the information required by
this section is reviewed and the city approves a plan.
(Ord. No. 2011-029, § 1, 12-5-2011)

(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.280 ‐ Maps and inventory.
The approximate location and extent of environmentally critical areas in the city are displayed on
various inventory maps available at the department of community development. More data will be included
as inventories are completed in compliance with the requirements of the growth management act. Maps
and inventory lists are guides to the general location and extent of environmentally critical areas.
Environmentally critical areas not shown are presumed to exist in the city and are protected under all the
provisions of this chapter. The shoreline jurisdiction areas are identified in the adopted shoreline maps
(AMC 20.93.970). In the event that any of the designations shown on the maps or inventory lists conflict
with the criteria set forth in this chapter, the criteria and site specific conditions shall control.
(Ord. No. 2011-029, § 1, 12-5-2011)

migration route for wildlife and due to other constraints such as roadways or buildings a fence would
prevent migration of those species. Alternative methods of demarcation will be required to replace
signage when determined that effectiveness of signage may be limited.
(b) Anyone may offer to dedicate an environmentally critical area easement or tract and its buffer to the
city even if not proposed as mitigation.
(c) Such easements or tracts shall cover the environmentally critical area as delineated by their defined
boundaries and their buffers.
(d) The basic controlling language for such easements shall be as follows, though site/resource specific
modifications may be made:
"Critical Area Protection Easement: This open space tract is intended to protect insert ECA type and native
vegetation and shall preclude: grading or any recontouring of the land; placement of structures, wells, leach
fields, utility lines and/or easements, and any other thing; vehicle activity; grazing; dumping; and the addition
or removal of vegetation, except pursuant to an approved restoration plan, and except that vegetation may
be selectively removed and/or pervious trails and/or utility lines compatible with native tree and shrub
vegetation may be placed in the buffer areas in locations approved by the Director of Planning and
Community Development."
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.300 ‐ Dedication of land and/or easements in lieu of required parks or open space.
The dedication of environmentally critical areas and their buffers may not be used for satisfying the
park or open space requirements of AMC Chapter 20.52 (Recreational Facilities and Open Space).
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.310 ‐ Increased buffer widths.
The permit-issuing authority shall require increased standard buffer zone widths on a case-by-case
basis when a larger buffer is necessary to protect environmentally critical area functions and values based
on local conditions. This determination shall be supported by appropriate documentation showing that it is
reasonably related to protection of the functions and values of the regulated environmentally critical area.
Such determination shall be attached as a permit condition and shall demonstrate that:
(1) A larger buffer is necessary to maintain viable populations of existing species; or
(2) The environmentally critical area is used by species proposed or listed by the federal government
or the state as endangered, threatened, sensitive, candidate, or monitor, critical or outstanding
potential habitat for those species or has unusual nesting or resting sites such as heron rookeries
or raptor nesting trees; or
(3) The adjacent land has minimal vegetative cover or slopes greater than fifteen percent and is
therefore susceptible to severe erosion, and erosion control measures will not effectively prevent
adverse environmentally critical area impacts.
(4) The recommended widths for buffers are based on the assumption that the buffer is vegetated
with a native plant community appropriate for the ecoregion or with one that performs similar
functions. If the existing buffer is unvegetated, sparsely vegetated, or vegetated with invasive
species that do not perform needed functions, the buffer should either be planted to create the
appropriate plant community or the buffer should be widened to ensure that adequate functions
of the buffer are provided. Generally, improving the vegetation will be more effective than
widening the buffer.

(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.320 ‐ Buffer width averaging.
Buffer widths may be modified by averaging. In no instance shall the buffer width be reduced by more
than twenty-five percent of the standard buffer unless specifically identified in other sections of this chapter.
Buffer width averaging shall be allowed only where the applicant demonstrates all of the following:
(1) That averaging is necessary to avoid an extraordinary hardship to the applicant caused by
circumstances peculiar to the property or that there would be a benefit to the environmentally
critical area;
(2) That the least impactive aspects of the proposed land use would be located adjacent to areas
where the buffer width is reduced;
(3) That width averaging will not adversely impact the environmentally critical area functional values;
and
(4) That the total area contained within the buffer after averaging is no less than that contained within
the standard buffer prior to averaging.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.330 ‐ Buffers to be retained in natural condition.
Except as otherwise specified, all buffers shall be retained in their natural condition. Where buffer
disturbance may or has occurred during construction, revegetation with native vegetation will be required.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.340 ‐ Building setbacks from buffers.
A building setback of fifteen feet is required from the edge of any critical area buffer, as defined in
subsequent sections of this chapter. Minor structural intrusions into the area of the building setback may
be allowed if the permit-issuing authority determines that such intrusions will not negatively impact the
environmentally critical area or cause the buffer vegetation to be trimmed or removed. The setback shall
be identified on the site plan.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.360 ‐ Reserved.
20.93.370 ‐ Non‐conforming activities.
Except for cases of discontinuance as part of normal agricultural practices, non-conforming uses shall
be governed by Part VI of this chapter and AMC Chapter 20.32 (Nonconforming Situations).
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.380 ‐ Assessment relief.
The Snohomish County Assessor's office considers environmentally critical area regulations in
determining the fair market value of land. Any owner of an undeveloped critical area who has dedicated an

easement or entered into a perpetual conservation restriction with the city of Arlington or a qualified
nonprofit organization to permanently control some or all regulated activities in that portion of land assessed
consistent with these restrictions shall be considered for exemption from special assessments to defray the
cost of municipal improvements such as sanitary sewers, storm sewers, and water mains.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.390 ‐ Mitigation plan requirements.
In the event that mitigation is required, the applicant shall be required to provide a mitigation plan for
approval by the community development director. The plan shall provide information on land acquisition,
construction, maintenance and monitoring of the replaced critical area. All mitigation plans shall include the
following submitted by the applicant or a qualified biologist, civil or geotechnical engineer:
(1) Specific goals and objectives describing site function, target species and selection criteria;
(2) Performance standards that shall include criteria for assessing goals and objectives;
(3) Contingency plans that clearly define course of action or corrective measures needed if
performance standards are not met;
(4) A legal description and a survey prepared by a licensed surveyor of the proposed development
site and location of the critical area(s) on the site;
(5) The need for performance or maintenance securities.
(6) A scaled plot plan that indicates the proposed construction in relation to zoning setback
requirements and sequence of construction location in relation to zoning setback requirements
and sequence of construction phases including cross-sectional details, topographic survey data
(including percent slope, existing and finished grade elevations) and other technical information
as required in sufficient detail to explain, illustrate and provide for:
(A) Soil and substrate conditions, topographic elevations, scope of grading and excavation
proposal, erosion and sediment treatment and source controls needed for critical area
construction and maintenance;
(B) Planting plans specifying plant species, types, quantities, location, size spacing, or density.
The planting season or timing, watering schedule, and nutrient requirements for planting,
and where appropriate, measures to protect plants from destruction; and
(C) Contingency or mid-course corrections plan and a minimum five-year monitoring and
replacement plan establishing responsibility for removal of exotic and nuisance vegetation
and permanent establishment of the critical area and all component parts.
(7) A clearly defined approach to assess progress of the project.
(8) The plan must indicate ownership, size, type, and complete ecological assessment including flora,
fauna, hydrology, functions, etc., of the critical area being restored or created; and
(9) The plan must also provide information on the natural suitability of the proposed site for
establishing the replaced critical area, including water source and drainage patterns, topographic
position, wildlife habitat opportunities, value of existing area to be converted, etc.
(10) Once the plan is implemented, as-builts shall also be submitted pursuant to department of public
works requirements.

20.93.410 ‐ Determination of boundary.
The community development director shall determine the boundaries of fish and wildlife conservation
areas. In doing so he may rely on information from qualified federal, state, county, or tribal agencies or on
a biological resources survey prepared by a qualified wildlife biologist per the department's biological
resources survey guidelines. Such reports or information may be required to be provided by an applicant
for an activity or permit at the request of the city. In the location of shoreline jurisdiction the adopted
Shoreline designation maps establish the boundary. When a project is at or below OHWM and within
shoreline setbacks, the OHWM shall be determined by a site-specific investigation using field indicators.

"species or habitat of local importance" and will be subject to the provisions of this chapter.
(b) Species or habitats of local importance include:
(1) None adopted as of December 5, 2011.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.430 ‐ Allowed activities.
Except where regulated by other sections of this or any other title or law, the following uses shall be
allowed within fish and wildlife conservation areas when the requirements of Section 20.93.440 (Fish and
Wildlife Conservation Areas—Requirements) have been met and mitigation adequate to alleviate any other
impacts has been proposed:
(1) Those activities listed in Section 20.93.220 (General Provisions—Allowed activities).

regarding the species, as determined by the community development director, who will consult
with other resource agencies including tribes as to their recommendations based on adopted
standards or guidance.
(3) Within the fifty-foot management zone of the buffer required pursuant to Section 20.93.440 (Fish
and Wildlife Conservation Areas—Requirements) the following uses are allowed as long as sixty-
five percent of native tree cover is established and maintained and the total effective impervious
area (TIA) remains below three percent:
(A) When the fifty-foot management zone is in an already developed state including buildings,
parking lots, lawn or ornamental landscaping stormwater management systems designed to
blend into the natural landscape allowing full mature growth of native trees and shrubs, and
provide the same or greater functional habitat that would occur in a naturally vegetated
buffer. Specifically, this does not include buried vaults, ecology block or grass-lined ponds
or swales (though ponds or swales planted with native vegetation may be allowed). Such
systems are required to provide diffuse effluent point(s) to the immediate edge of the no-
touch buffer to allow infiltration and polishing. Walkways and trails, provided that those
pathways are limited to minor crossings having no adverse impact on water quality. They
should be generally parallel to the perimeter of the wetland, located only in the outer twenty-
five percent of the wetland buffer area, and located to avoid removal of significant trees.
They should be limited to pervious surfaces no more than five feet in width for pedestrian
use only. Raised boardwalks utilizing non-treated pilings may be acceptable.

(B) Utility easements and access routes that are built so as to not affect the lateral or vertical
hydrology of the system, and are compatible with full maturity of native tree and shrub
species.
(C) Other uses as may be approved by the city's natural resources manager as recommended
in a local, state or federal watershed management plan or low impact development
regulations.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.440 ‐ Requirements.
(a) Except as provided in subsections (b) and (c):
(1) For endangered or threatened salmonid fish and wildlife conservation areas, a one hundred fifty-
foot buffer shall be required for all regulated activities adjacent to the fish and wildlife conservation
areas. This buffer shall consist of a one hundred-foot area closest to the stream or river being
designated a native growth protection easement in which no human activities may be allowed
(except as provided by Section 20.93.430 (Fish and Wildlife Conservation Areas—Allowed
activities), and the remaining fifty-foot zone being designated a management zone, in which
vegetation may be managed solely for public health and safety reasons that may threaten
structures or public infrastructure. The natural resource may require a landowner to have an
assessment performed by a professional arborist to determine if a tree is hazardous. If found
hazardous the methods of removal will utilize options that will result in some level of habitat
function (i.e. snag, nurse log, etc). Buffers for salmonid fish and wildlife conservation areas shall
be measured pursuant to Section 20.93.730 (Streams, Creeks, Lakes, and Other Surface
Water—Requirements).
(2) For all other fish and wildlife conservation areas, the applicant shall have a habitat protection plan
prepared by a qualified biologist, in which appropriate buffers and other protection shall be
identified based on the best available science and/or standards promulgated by the state or
federal agency with jurisdiction for the identified species being protected. Buffers shall be
measured from the fish and wildlife conservation areas boundary as surveyed in the field.
(b) Buffer widths may be increased based on recommendations by the state or federal agency with
jurisdiction.
(c) Buffer widths from fish and wildlife conservation areas may be decreased in areas where specific
project recommendations can be found in Section 20.93.320 of this chapter, local watershed recovery
plans, the Shoreline Master Program has identified allowed uses, a habitat protection plan, or either a
property-specific or programmatic biological assessment showing that the proposal would have
negligible adverse impact on the protected species or habitat (with or without mitigation) has been
approved by the state or federal agency with jurisdiction. Said biological assessments would be
prepared by the applicant in a format approved by the agency with jurisdiction. The width of the buffer
would be determined through this biological assessment approval process but could in no case be
reduced to less than that required for the underlying environmentally critical areas by other sections of
this chapter.
(d) For streams upstream from an endangered or threatened salmonid fish and wildlife conservation area,
if requested by the city, applicants shall have prepared a report analyzing potential downstream
impacts to the FWCA and propose appropriate measures to mitigate any identified significant impacts.
Such reports shall be prepared by a qualified biologist.
(e) The applicant shall dedicate a functionally exclusive environmentally critical area easement for the
protection of wildlife and/or habitat over the fish and wildlife conservation areas and its buffer, as
determined above. Where such requirement leads to, or would in the opinion of the permit-issuing
authority lead to, a court finding of a taking mitigation as described in Section 20.93.450 (Fish and
Wildlife Conservation Areas—Mitigation) may be considered.
Commented [CY5]: Shouldn’t this be regulated by the
BiOp and ESA regarding CMZ and Riparian Buffer Zones and
not in a CAO ordinance?

20.93.450 ‐ Mitigation.
In order to avoid significant environmental impacts and, if in the opinion of the permit-issuing authority
the requirements listed in Section 20.93.440 (Fish and Wildlife Conservation Areas—Requirements) do not
adequately mitigate impacts, the applicant for a land use activity or development permit may consider
performing the following actions, listed in order of preference. What is considered adequate mitigation will
depend on the nature and magnitude of the potential impact. Specific mitigation requirements are outlined
in the Shoreline Master Program regulations.
(1) Where on-site protection is not possible, dedicate a functionally exclusive easement for the
protection of equivalent (in type and value) wildlife and/or habitat over fish and wildlife
conservation areas and a one hundred fifty-foot buffer on off-site fish and wildlife conservation
areas at a minimum two to one ratio (two offsite areas for every one onsite area impacted) on
property that would likely not be required to dedicate such an easement were it to undergo a
permitting process. If functionally equivalent habitat is not available, then a higher ratio may be
considered to compensate. The location of any off-site fish and wildlife conservation areas shall
be located as near to the site as possible, following this preferred order:
(A) Hydrologically connected to the impacted fish and wildlife conservation areas or via an intact
habitat corridor,
(B) Elsewhere within the city,
(C) Within the Arlington UGA,
(D) Within the sub-basin, and
(E) Watershed.
(Ord. No. 2011-029, § 1, 12-5-2011)
Part V. ‐ Frequently Flooded Areas
20.93.500 ‐ Classification.
Classification for flood zones shall be consistent with the one hundred-year floodway and floodplain
designations as adopted by the city, or where the city has not adopted such a designation, by the one
hundred-year flood zone designation of the Federal Emergency Management Agency and the National
Flood Insurance Program. Any such designations adopted by the city shall consider the following criteria if
and when designating and classifying these areas:
(1) Flooding impact to human health, safety, and welfare and to public facilities and services; and,
(2) Documentation including federal, state and local laws, regulations and programs, local maps and
federally subsidized flood insurance programs; and,
(3) The future floodplain defined as a channel of the stream and that portion of the adjoining floodplain
which is necessary to contain and discharge the base flood flow at build-out without any
measurable increase in flood heights.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.510 ‐ Determination of boundary.
Commented [CY7]: Part V is part of our Floodplain
Ordinance, Section 20.64. so is it required in our CAO as
well?
Commented [GD(8]: I agree that Chapter 20.64 is the
more appropriate place for these regulation’s.

Formatted: Centered
The boundary of a flood zone shall be contiguous with the one hundred-year floodway and floodplain
designations as adopted by the city, or where such a designation has not been adopted by the city, the one
hundred-year floodplain designation of the Federal Emergency Management Agency (FEMA) and the
National Flood Insurance Program where it has been delineated (shown on flood insurance rate maps
(FIRM). Where this information does not exist, the boundary determination shall be made by a licensed
engineer and based upon the same criteria used by FEMA including the consideration of the channel
migration zone. The floodplain administrator shall confirm this determination.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.520 ‐ Allowed activities.
Except where regulated by other sections of this or any other title or law, the following uses shall be
allowed within floodways or floodplains when the requirements of Section 20.93.530 (Frequently Flooded
Areas—Requirements) have been met and mitigation adequate to alleviate any other impacts has been
proposed:
(1) Floodways.
(A) Those activities allowed per the Shoreline Master Program regulations and Section
20.93.220 (General Provisions—Allowed activities).
(B) Outdoor recreational activities (including fishing, bird watching, hiking, boating, swimming,
canoeing, bicycling, etc.) and aquatic recreation facilities authorized by this Chapter 20.93.
(C) Those uses allowed by Section 20.64.150 (Permissible uses within floodways).
(2) Floodplains.
(A) All those activities allowed in floodways,

(C) Those uses allowed by and consistent with the regulations of Chapter 20.64 (Floodways,
Floodplains, Drainage, and Erosion).
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.530 ‐ Requirements.
All land uses and development proposals shall comply with the regulations for general and specific
flood hazard protection (see Chapter 20.64). Development shall not reduce the effective base flood storage
volume. Reduction of the floodwater storage volume effectiveness due to grading, construction, or other
regulated activities shall be compensated for by creating on- or off-site detention and/or retention ponds.
Effective storage capacity must be maintained.
When new flood storage is being constructed to mitigate for loss of flood storage area that is in the
floodplain but not vegetated and not used as salmon habitat the effective storage must be constructed in a
manner that will not cause stranding of fish. When new flood storage is being constructed to mitigate for
loss of flood storage in an area with existing native vegetation and used by salmon for habitat it must be
revegetated with native plants and graded to prevent stranding.
Base flood data and flood hazard notes shall be on the face of any recorded plat or site plan including,
but not limited to, base flood elevations, flood protection elevation, boundary of floodplain and zero rise
floodway.

20.93.540 ‐ Mitigation.
If potential flooding impacts cannot be avoided by design or by providing on- or off-site detention and/or
retention ponds, other forms of mitigation may be considered in order to avoid significant environmental
impacts. Applicants must provide mitigation plans exploring and analyzing any proposed mitigation
measures, which must be consistent with the Shoreline Master Program and the regulations of AMC
Chapter 20.64 (Floodways, Floodplains, Drainage, and Erosion).
(Ord. No. 2011-029, § 1, 12-5-2011)
Part VI. ‐ Geologically Hazardous Areas
20.93.600 ‐ Classification.
(a) Geologically hazardous areas include areas susceptible to erosion, sliding, earthquakes, liquefaction,
or other geological events. Geologically hazardous areas shall be classified based upon the history or
existence of landslides, unstable soils, steep slopes, high erosion potential or seismic hazards. In
determining the significance of a geologically hazardous area the following criteria shall be used:
(1) Potential economic, health, safety, and environmental impact related to construction in the area;

slope; and,
(C) Class 5, class URS (unstable recent slides).
(2) Landslide hazard areas shall include areas subject to severe risk of landslide based on a
combination of geologic, topographic and hydrologic factors. Some of these areas may be
identified in the Department of Ecology Coastal Zone Atlas, or through site-specific criteria.
Landslide hazard areas include any of the following:
(A) Areas characterized by slopes greater than fifteen percent and impermeable soils (typically
silt and clay) frequently interbedded with permeable granular soils (predominantly sand and
gravel) or impermeable soils overlain with permeable soils or springs or groundwater
seepage;
(B) Any area that has exhibited movement during the Holocene epoch (from ten thousand years
ago to present) or which is underlain by mass wastage debris of that epoch;
(C) Any area potentially unstable due to rapid stream incision, stream bank erosion or
undercutting by wave action;

(D) Any area located on an alluvial fan presently subject to or potentially subject to inundation
by debris flows or deposition of steam-transported sediments;
(E) Any area with a slope of thirty-three percent or greater and with a vertical relief of ten or more
feet except areas composed of consolidated rock;
(F) Any area with slope defined by the United States Department of Agriculture Soil
Conservation Service as having a severe limitation for building site development; and
(G) Any shoreline designated or mapped as class U, UOS, or URS by the Department of Ecology
Coastal Zone Atlas.
(3) Slopes.
(A) Moderate slopes shall include any slope greater than or equal to fifteen percent and less
than thirty-three percent.
(B) Steep slopes shall include any slope greater than or equal to thirty-three percent.
(4) Seismic hazard areas shall include areas subject to severe risk of earthquake damage as a result
of seismic induced settlement, shaking, slope failure or soil liquefaction. These conditions occur
in areas underlain by cohesion less soils of low density usually in association with a shallow
groundwater table.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.610 ‐ Determination of boundary.
The community development director, relying on a geotechnical or similar technical report and other
information where available and pertinent, shall make determination of a boundary of a geologically
hazardous area. Such reports or information shall be provided by an applicant for an activity or permit at
the request of the city.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.620 ‐ Allowed activities.
Except where regulated by other sections of this or any other title or law, the following uses shall be
allowed within geologically hazardous areas when the requirements of Section 20.93.630 (Geologically
Hazardous Areas—Requirements) have been met and mitigation adequate to alleviate any other impacts
has been proposed:
(a) Those activities allowed per Section 20.93.220 (General Provisions—Allowed activities).
(b) Any other use allowed per the zone, and Shoreline Master Program, provided that it meets the
requirements of Section 20.93.630 (Geologically Hazardous Areas—Requirements) and will not
have a detrimental impact on the health, safety, and welfare of the public, or will not negatively
impact neighboring properties.
(c) Recontouring of land to eliminate geologically hazardous areas, including steep slopes, is
expressly prohibited unless otherwise approved through the land use permit process (not the
construction plan review process). The permit issuing authority may approve recontouring to
eliminate geological hazardous areas only upon finding that such action would serve the health,
safety, and welfare of the general public and not just a particular development proposal.

Formatted: Centered
(a) Erosion hazard areas. All development proposals on sites containing erosion hazard areas shall
comply with the following requirements:
(1) Erosion control plan. The applicant shall submit an erosion control plan prior to the approval of
any permit. Plans shall be consistent with the guidelines set forth in the Uniform International
Building Code (U IBC) grading section and the department of public works' construction standards
and specifications.
(2) Alteration. All authorized clearing for roads, utilities, etc., shall be limited to the minimum
necessary to accomplish the engineering design. Alterations of erosion hazard sites shall meet
the requirements of AMC Chapter 20.44, Part II (Land Clearing, Grading, Filling, and Excavation).
(b) Landslide hazard areas. All development proposals on sites containing landslide hazard areas shall
comply with the following requirements:
(1) Alterations. Landslide hazard areas located on slopes thirty-three percent or greater shall be
altered only as allowed under standards for steep slopes set forth in this section. Landslide hazard
areas and land adjacent to such a hazard area located on slopes less than thirty-three percent
may be altered if:
(A) The proposal will not increase surface water discharge or sedimentation and will not
decrease adjacent property slope stability; and
(B) It can be demonstrated through geotechnical analysis that there is no significant risk to the
development proposal or adjacent properties or that the proposal can be designed so that
the landslide hazard is significantly eliminated or mitigated such that the site and adjacent
property are rendered as safe as an area without landslide hazards.
(2) Buffers. Unless the alteration is approved under the provisions in subsection (1) (Alterations), a
minimum buffer of fifty feet shall be provided from the edges of all landslide hazard areas
regardless of slope. The buffer may be extended beyond these limits to mitigate erosion hazards.
(3) Building setback lines. All buildings are required to be set back a minimum of fifteen feet from the
buffer or landslide hazard area.
(c) Slopes. Grading, vegetation removal, and other site disturbances on slopes can lead to erosion or
landslides. If the amount of the slope disturbed is decreased, then the risk of erosion and landslides
decreases. The risk is also less on slopes that are less steep. Therefore, all site disturbances on
moderate and steep slopes and their buffers shall be reviewed and certain standards are required to
be met depending on the percent of slope.
(1) The maximum slope and buffer disturbance allowed, unless restricted for other reasons, is:
Table 20.93‐2: Slope Disturbance Allowed

(2) Development on moderate and steep slopes shall meet the following standards:
(A) Development must be located to minimize disturbance and removal of vegetation and also
to protect most critical areas and retain open space.
(B) Structures must be located or clustered where possible to reduce disturbance and maintain
natural topographic character.
(C) Grading shall be minimized;
(D) Structures should conform to the natural contour of the slope, with foundations tiered where
possible to conform to existing topography of site.
(E) Natural surface or sub-surface drainage courses shall be preserved.
(F) All development proposals shall be designed to minimize the footprint of building and other
disturbed areas. Common access drives and utility corridors are encouraged.
(G) All development shall be designed to minimize impervious lot coverage and should
incorporate under- or over-structure parking and multi-level structures.
(H) Roads, walkways and parking areas should be designed to parallel the natural contours.
(I) Access shall be in the least critical area of the site.
(3) Additional standards for steep slopes: All proposed development on steep slopes shall be avoided
if possible. Alterations are allowed in only the following instances provided that the standards in
subsections (1) and (2), can be met; and, where it has been demonstrated through a soils report
prepared by a geotechnical engineer that no adverse impact will result from the proposal and
where approved surface water conveyance will result in minimum slope and vegetation
disturbance:
(A) The construction of approved public or private trails provided they are constructed in a
manner that is not detrimental to surface water runoff control (e.g., cable lift access); and
(B) The construction of public or private utility corridors in accordance with Chapter 20.93
regulations provided it has been demonstrated that such alterations will not increase
landslide or erosion risks.
(4) In all other cases, no disturbance is allowed on a steep slope and a minimum fifteens-foot
vegetated buffer shall be established from the top, toe and along all sides of the slope. The buffer
may be extended beyond these limits on a case-by-case basis to mitigate landslide and erosion
hazards.
(d) Seismic hazard areas. Standards for development in seismic hazard areas shall be in accordance with
the provisions in the IBC, as adopted by the cCity of Arlington.
(e) For all geological hazardous areas on which development is not permitted by the above regulations,
the applicant shall dedicate to the city an exclusive environmentally critical area easement for the
protection of geological hazardous areas over the environmentally critical area and a buffer consistent
with the standards listed above.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.640 ‐ Mitigation.
If potential geologic impacts cannot be avoided by adhering to the above requirements, other forms of
mitigation may be considered. Applicants must provide mitigation plans exploring and analyzing any
proposed mitigation measures. What is considered adequate mitigation will depend on the nature and

Part VII. ‐ Streams, Creeks, Rivers, Lakes and Other Surface Water
20.93.700 ‐ Classification.
(a) The city hereby adopts the stream classification system of the state, as specified in WAC 222-16-030,
as may be amended. Briefly, these are as follows (see WAC 222-16-030 for complete definitions of
types):
(1) Type S water means all the waters, within their ordinary high-water mark, as inventoried as
"shorelines of the state" under Chapter 90.58 RCW and the rules promulgated pursuant to
Chapter 90.58 RCW, but not including those waters' associated wetlands as defined in Chapter
90.58 RCW.
(2) Type F-ESA water means all the waters meeting the criteria of Type F stream, but has been
identified as having presumed use by ESA listed fish species.
(b) "Type F water" shall mean segments of natural waters that are not classified as Type 1 water and have
a substantial fish, wildlife, or human use. These are segments of natural waters and periodically
inundated areas of their associated wetlands, which:
(1) Are diverted for domestic use by more than one hundred residential or camping units or by a
public accommodation facility licensed by the state to serve more than one hundred persons,
where such diversion is determined by the Washington State Department of Ecology to be a valid
appropriation of water and the only practical water source for such users. Such waters shall be
considered to be Type 2 water upstream from the point of such diversion for one thousand five
hundred feet or until the drainage area is reduced by fifty percent, whichever is less;
(2) Are within a federal, state, local, or private campground having more than thirty camping units:
Provided, that the water shall not be considered to enter a campground until it reaches the
boundary of the park lands available for public use and comes within one hundred feet of a
camping unit, trail or other park improvement;
(3) Are used by substantial numbers of anadromous or resident game fish for spawning, rearing or
migration. Waters having the following characteristics are presumed to have highly significant fish
populations:
(A) Stream segments having a defined channel twenty feet or greater in width between the
ordinary high-water marks and having a gradient of less than four percent.
(B) Lakes, ponds, or impoundments having a surface area of one acre or greater at seasonal
low water; or
(4) Are used by salmonids for off-channel habitat. These areas are critical to the maintenance of
optimum survival of juvenile salmonids. This habitat shall be identified based on the following
criteria:
(A) The site must be connected to a stream bearing salmonids and accessible during some
period of the year; and
(B) The off-channel water must be accessible to juvenile salmonids through drainage with less
than a five percent gradient.
Formatted: Highlight
COA and ECY Draft – 3/16
Page 22
Formatted: Centered
(C) Ponds or impoundments having a surface area of less than one-half acre at seasonal low
water and having an outlet to an anadromous fish stream.
(5) Are highly significant for protection of downstream water quality. Tributaries which contribute
greater than twenty percent of the flow to a Type S or F water are presumed to be significant for
one thousand five hundred feet from their confluence with the Type S or F water or until their
drainage area is less than fifty percent of their drainage area at the point of confluence, whichever
is less.
(c) Type Np water. Segments of natural waters within the bankfull width of defined channels that are
perennial nonfish habitat streams. Perennial streams are waters that do not go dry any time of the
year of normal rainfall. However, for the purpose of water typing, Type Np waters include the
intermittent dry portions of the perennial channel below the uppermost point of perennial flow. Np
waters begin downstream of the point along the channel where the contributing basin area is at least
fifty-two acres in size.
(d) Type Ns water shall be segments of natural waters within the bankfull width of the defined channels
that are not Type S, F, or Np waters. These are seasonal, nonfish habitat streams in which surface
flow is not present for at least some portion of a year of normal rainfall and are not located downstream
from any stream reach that is a Type Np water. Ns waters must be physically connected by an above-
ground channel system to Type S, F, or Np waters.
(e) Non-natural water course means constructed vegetated swales and ditches that are designed and
installed for the express purpose of periodically moving storm water not associated with naturally
occurring streams.

Part VIII. ‐ Wetlands
20.93.800 ‐ Classification.
(a) Wetlands shall be rated according to the Washington State wetland rating system for; Washington
State Wetland Rating System for Western Washington—Revised, Ecology Publication #04 14-06-025)
029 or as revised by ecology Ecology. Wetland rating categories shall be applied as the wetland exists
at the time of the adoption of this title or as it exists at the time of an associated permit application.
Wetland rating categories shall not change due to illegal modifications. Wetlands identified as having
local significance in hydrologic and habitat functions may be rated higher based on importance.
(b) Wetland types.
(1) Category I. Category I wetlands are:
(A) Relatively undisturbed estuarine wetlands larger than one acre;
(B) Wetlands that are identified by scientists of the Washington Natural Heritage Program/DNR
as high quality wetlands of high conservation value;
(C) Bogs;
(D) Mature and old-growth forested wetlands larger than one acre;
(E) Wetlands in coastal lagoons; or
(F) Wetlands that perform many functions well and score seventy 23 or above.
Category I wetlands represent a unique or rare wetland type, are more sensitive to disturbance than
most wetlands, are relatively undisturbed and contain some ecological attributes that are impossible to
replace within a human lifetime, or provide a very high level of functions.
(2) Category II. Category II wetlands are:
(A) Estuarine wetlands smaller than one acre, or disturbed estuarine wetlands larger than one
acre;
(B) A wetland identified by the Washington State Department of Natural Resources as
containing "sensitive" plant species;
(C) A bog between one-fourth; and one-half; acre in size;
(D) An interdunal wetland larger than one acre; or
(E) Wetlands with a moderately high level of functions;
COA and ECY Draft – 3/16
Page 25
Formatted: Centered
(F) Wetland scoring between fifty-one 20 and sixty-nine 22 points;
(G) Wetlands identified as having local significance in reducing flooding or providing habitat.
Category II wetlands are difficult, though not impossible, to replace, and provide high levels of some
functions. These wetlands occur more commonly than Category I wetlands, but they still need a relatively
high level of protection.
(3) Category III. Category III wetlands are:
(A) Wetlands with a moderate level of functions scoring between thirty 16 and fifty 19 points; or
that can be adequately replaced with a well-planned mitigation project.
(B) Interdunal wetlands between 0.1 and one acre in size.
Generally, wetlands in this category may have been disturbed in some way and are often less diverse
or more isolated from other natural resources in the landscape than Category II wetlands.
(4) Category IV. Category IV wetlands have the lowest levels of functions scoring less than thirty 16
points and are often heavily disturbed. These are wetlands that should be replaceable, and in
some cases may be improved. However, experience has shown that replacement cannot be
guaranteed in any specific case. These wetlands may provide some important functions and
should be protected to some degree.
(Ord. No. 2011-029, § 1, 12-5-2011)
20.93.810 ‐ Determination of Boundary.
(a) The community development director, relying on a field investigation supplied by an applicant, and
applying the wetland definition provided in this chapter shall determine the location of the wetland
boundary. Qualified professional and technical scientists shall perform wetland delineations.
Identification of wetlands and delineation of their boundaries pursuant to this chapter shall be done in
accordance with the approved federal wetland delineation manual and applicable regional
supplements. All areas within the city meeting the wetland designation criteria in that procedure are
hereby designated critical areas and are subject to the provisions of this chapter. Criteria to be included
in required wetland identification reports may be found in Section 20.93.390 (Mitigation plan
requirements). The applicant is required to show the location of the wetland boundary on a scaled
drawing as a part of the permit application.
(1) Designating, defining, and identifying wetlands. Wetlands are those areas, identified in
accordance with RCW 90.58.030: "Wetlands" means areas that are inundated or saturated by
surface water or groundwater at a frequency and duration sufficient to support, and that under
normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated
soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Wetlands
do not include those artificial wetlands intentionally created from non-wetland sites, including, but
not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities,
wastewater treatment facilities, farm ponds, and landscape amenities, or those wetlands created
after July 1, 1990, that were unintentionally created as a result of the construction of a road, street,
or highway. Wetlands may include those artificial wetlands intentionally created from nonwetland
areas to mitigate the conversion of wetlands. All areas within the [city/county] meeting the criteria
in the wetland definition regardless of whether these areas have previously been identified or
mapped, are hereby designated critical areas and are subject to the provisions of this title.
(2) Mapping.
(A) The approximate location and extent of wetlands are shown on the critical area(s) maps
adopted in the city of Arlington Comprehensive Plan. Additionally, soil maps produced by
U.S. Department of Agriculture Natural Resources Conservation Service may be useful in
helping to identify potential wetland areas. These maps are to be used as a guide for the
COA and ECY Draft – 3/16
Page 26
Formatted: Centered
city, project applicants, and/or property owners to identify potential wetland areas that may
be subject to the provisions of this title.
(B) It is the actual presence of wetlands on a parcel, as delineated by the requirements of the
methods in the approved federal wetland delineation manual and applicable regional
supplements in accordance with WAC 173-22-035, that establishes duties under this
chapter. The exact location of a wetland's boundary shall be determined through the
performance of a field delineation by a qualified wetlands professional, applying the
approved federal wetland delineation manual and applicable regional supplements in
accordance with WAC 173-22-035.
(b) Where the applicant has provided a delineation of the wetland boundary, the community development
director shall verify the accuracy of, and may render adjustments to, the boundary delineation. In the
event the applicant contests the adjusted boundary delineation, the community development director
shall, at the applicant's expense, obtain expert services to render a final delineation.
(c) When agreed to by the applicant, the community development director may waive the requirement that
the applicant provide the delineation of boundary and rely on staff delineation. The community
development director shall consult with qualified professional scientists and technical experts or other
experts as needed to perform the delineation. The applicant will be charged for the costs incurred.
Where the community development director performs a wetland delineation at the request of the
applicant, such delineation shall be considered a final determination.

20.93.820 ‐ Allowed activities.
Except where regulated by other sections of this, Shoreline Master Program or any other title or law,
and provided they are conducted using best management practices, the following uses shall be allowed
within wetlands and their buffers when the requirements of Sections 20.93.830 (Wetlands—Requirements)
and 20.93.840 (Wetlands—Mitigation) have been met, state and federal approvals have been granted when
required, and mitigation adequate to alleviate any other impacts has been proposed:
Generally uses will be required to avoid and minimize impacts, and compensate for the impact that
may reduce the functions of the wetland or its buffers:
(1) Those uses listed in Section 20.93.220 (General Provisions—Allowed activities).
(2) In Class III and Class IV wetlands only, access to developable portions of legal lots where:
(A) There is no other feasible method of accessing the property,
(B) Altering the terrain would not cause drainage impacts to neighboring properties, and
(C) Not more than two thousand five hundred square feet of wetland is impacted, and mitigated.
(3) Permitted uses in a wetland buffer—Regulated activities shall not be allowed in a buffer except
for the following:
(A) Activities having minimal adverse impacts on buffers and no adverse impacts on regulated
wetlands. These may include low intensity, passive recreational activities such as low impact
trails in the outer twenty-five percent, non-permanent wildlife watching blinds, short-term
scientific or educational activities, and sports fishing;
(B) With respect to Category III and IV wetlands, stormwater management facilities having no
reasonable alternative on-site location; or
(C) With respect to Category III and IV wetlands, development having no feasible alternative
location when the following conditions have been met: Impacts are the minimum necessary;
Buffer impacts are mitigated through buffer averaging.
Commented [GD(9]: Recommend deleting references to

Formatted: Centered
(4) Those activities and uses conducted pursuant to the Washington State Forest Practices Act and
its rules and regulations, WAC 222-12-030, where state law specifically exempts local authority,
except those developments requiring local approval for Class 4—General Forest Practice Permits
(conversions) as defined in RCW 76.09 and WAC 222-12:
(A) Conservation or preservation of soil, water, vegetation, fish, shellfish, and/or other wildlife
that does not entail changing the structure or functions of the existing wetland.
(B) The harvesting of wild crops in a manner that is not injurious to natural reproduction of such
crops and provided the harvesting does not require tilling of soil, planting of crops, chemical
applications, or alteration of the wetland by changing existing topography, water conditions,
or water sources.
(C) Drilling for utilities/utility corridors under a wetland, with entrance/exit portals located
completely outside of the wetland buffer, provided that the drilling does not interrupt the
ground water connection to the wetland or percolation of surface water down through the
soil column. Specific studies by a hydrologist are necessary to determine whether the ground
water connection to the wetland or percolation of surface water down through the soil column
will be disturbed.
(D) Enhancement of a wetland through the removal of non-native invasive plant species.
Removal of invasive plant species shall be restricted to hand removal unless permits from
the appropriate regulatory agencies have been obtained for approved biological or chemical
treatments. All removed plant material shall be taken away from the site and appropriately
disposed of. Plants that appear on the Washington State Noxious Weed Control Board list
of noxious weeds must be handled and disposed of according to a noxious weed control
plan appropriate to that species. Re-vegetation with appropriate native species at natural
densities is allowed in conjunction with removal of invasive plant species.
(E) Educational and scientific research activities.
(F) Normal and routine maintenance and repair of any existing public or private facilities within
an existing right-of-way, provided that the maintenance or repair does not expand the
footprint of the facility or right-of-way and impacts are mitigated.
(G) Stormwater management facilities. Stormwater management facilities are limited to
stormwater dispersion outfalls and bioswales. They may be allowed within the outer twenty-
five percent of fifty-foot management zone, whichever is most protective, of Category II, III
or IV wetlands buffers when the fifty-foot management zone is in an already developed state
including buildings, parking lots, lawn or ornamental landscaping stormwater management
systems designed to blend into the natural landscape allowing full mature growth of native
trees and shrubs, and provide the same or greater functional habitat that would occur in a
naturally vegetated buffer. Specifically, this does not include buried vaults, ecology block or
grass-lined ponds or swales (though ponds or swales planted with native vegetation may be
allowed). Such systems are required to provide diffuse effluent point(s) to the immediate
edge of the no-touch buffer to allow infiltration and polishing, provided that:
(i) No other location is feasible; and
(ii) The location of such facilities will not degrade the functions or values of the wetland;
and
(iii) Stormwater management facilities are not allowed in intact buffers of Category I
wetlands.
(H) Nonconforming uses. Repair and maintenance of nonconforming uses or structures, where
legally established within the buffer, provided they do not increase the degree of
nonconformity.

20.93.830 ‐ Requirements.
(a) Buffers—ECA buffers shall be required for all regulated activities adjacent to regulated wetlands as
provided in Table 20.93-4, unless modified per subsection (b). Any wetland created, restored, or
enhanced as compensation for approved wetland alterations shall also include the standard buffer
required for the category of the created, restored, or enhanced wetland. All buffers shall be measured
from the wetland boundary as determined pursuant to Section 20.93.810 (Wetlands—Determination
of boundary). The width of the wetland buffer zone shall be determined according to wetland category
and the proposed land use. These buffers have been established to reflect the impact of land use
intensity on wetland functions and values.
(b) The standard buffer widths in Table 20.93-4 have been established in accordance with the best
available science. They are based on the category of wetland and the habitat score as determined by
a qualified wetland professional using the Washington state wetland rating system for Western
Washington.
(1) The use of the standard buffer width requires the implementation of the measures in Table 20.93-
5, where applicable, to minimize the impacts of the adjacent land uses.
(2) If an applicant chooses not to apply the mitigation measures in Table 20.93-5 or other sections of
this document, then a thirty-three percent increase in the width of all buffers is required. For
example, a seventy-five-foot buffer with the mitigation measures would be a one hundred-foot
buffer without them.
(3) The standard buffer widths assume that the buffer is vegetated with a native plant community
appropriate for the ecoregion. If the existing buffer is unvegetated, sparsely vegetated, or
vegetated with invasive species that do not perform needed functions, the buffer should either be
planted to create the appropriate plant community or the buffer should be widened to ensure that
adequate functions of the buffer are provided.
(4) Additional buffer widths are added to the standard buffer widths as indicated in Table 20.93-4.
(c) The applicant shall dedicate to the city an exclusive environmentally critical area easement for the
protection of wetlands over the environmentally critical area and a buffer consistent with the standards
listed in subsection (a).

easement for the protection of equivalent (in ecological type and function) wetland and its buffer
on an off-site wetland at the ratio listed in Table 20.93-6 according to the wetland type. The
location of any off-site wetland mitigation area shall be located within the same watershed as the
impact and as near to the site as possible, following this preferred order:
(A) Contiguous to the impacted wetland,
(B) Within the same drainage basin where it would best provide the same function as the
impacted wetland, and
(C) Elsewhere within the city.
(b) All wetland restoration, creation and/or enhancement projects required pursuant to this chapter either
as a permit condition or as the result of an enforcement action shall follow a mitigation plan prepared
in conformance to the requirements of Section 20.93.390 (Mitigation plan requirements).
(c) Location of mitigation. When compensatory measures are appropriate pursuant to the mitigation
priority sequence above, preferential consideration shall be given to measures that replace the
impacted functions directly and in the immediate vicinity of the impact. However, alternative
compensatory mitigation within the watershed sub-basin that addresses limiting factors or identified
critical needs for shoreline resource conservation based on watershed or comprehensive resource
management plans applicable to the area of impact may be authorized. If there are no previously
identified mitigation opportunities in the impacted sub-basin identified in local watershed or
comprehensive plans the applicant will use a watershed approach in selecting mitigation sites utilizing
Selecting Wetland Mitigation Sites Using a Watershed Approach (Western Washington) (Publication
#09-06-32). Authorization of compensatory mitigation measures may require appropriate safeguards,
terms, or conditions as necessary to ensure no net loss of ecological functions (WAC 173-26-

20.93.010 - Purpose and intent.
This chapter establishes regulations for the protection of environmentally critical areas
(ECAs) within the City’s shoreline jurisdiction, including critical areas, natural resource lands,
and protective buffers. While it is intended that this chapter fulfill the mandates of the
Washington State Shoreline Growth Management Act, that is not its sole purpose: Its primary
purpose is to fulfill the legislative intent of the city of Arlington, which is to protect the public
ORDINANCE No. 2016-XXX 2
health, safety, and welfare of the citizens of Arlington by providing for the long-term
preservation of natural systems and their functions. This is to be accomplished by establishing
prohibitions, mitigation requirements, and minimum standards for the use and development
of properties that contain or adjoin environmentally critical areas. Additionally, this chapter
is intended to:
(1) If at all possible, avoid impacts to environmentally critical areas. If this is not
practicable, then:
(A) Minimize or limit the degree or magnitude of actions and their implementation
by using appropriate technology or by taking affirmative steps to avoid or reduce
impacts.
(B) Mitigate any impacts by repairing, rehabilitating, or restoring the affected
environment.
(C) Reduce or eliminate any impacts over time by preservation and maintenance
operations during the life of the action.
(D) Compensate for unavoidable impacts by replacing, enhancing or providing
substitute resources or environments through monitoring of specific and
cumulative impacts.
(2) Protect the public from personal injury, loss of life, or property damage due to
flooding, erosion, landslides, seismic events, or soil subsidence.
(3) Protect against publicly financed expenditures due to the misuse of environmentally
critical areas that cause:
(A) Unnecessary maintenance and replacement of public facilities;
(B) Publicly funded mitigation of avoidable impacts;
(C) Cost for public emergency rescue and relief operations where the causes are
avoidable;
(D) Degradation of the natural environment.
(4) Protect aquatic resources.
(5) Protect unique, fragile, and valuable elements of the environment, including wildlife
and its habitat.
(6) Alert appraisers, assessors, owners, potential buyers, or lessees to the development
limitations of environmentally critical areas.

environmentally critical areas when approving, conditioning, or denying applications
for public or private development proposals.
(8) Give guidance to the development of comprehensive plan policies in regard to the
natural systems and environment of the Arlington Watershed(s).
(9) Provide property owners and developers with succinct information regarding the
city's requirements for property development, thus rationalizing and accelerating the
development permit application process.
ORDINANCE No. 2016-XXX 3
Section 4. Arlington Municipal Code Chapter 20.93.100 shall be and hereby is
amended to add the following definition:
"Development" means any manmade change to improved or unimproved real estate,
including but not limited to buildings or other structures, mining, dredging, filling,
grading, paving, excavation or drilling operations or storage of equipment or materials
located within the area of special flood hazard, subdivision of land, removal of
substantial amounts of vegetation, or alteration of natural site characteristics.
Section 5. Arlington Municipal Code Section 20.93.100 shall be and hereby is
amended to delete the following definition:
"Frequently flooded areas". Lands indicated on the most current FEMA map to be
within the one hundred-year flood plain. These areas include, but are not limited to,
streams, lakes, coastal areas, and wetlands. Local areas not identified on FEMA maps
that experience frequent periods of inundation.
Section 6. Arlington Municipal Code Section 20.93.200 shall be and hereby is
amended to read as follows:
This chapter applies to environmentally critical areas within the city's and its shoreline
jurisdiction. The maps adopted in AMC 20.93.970 show the general location of the
city's shoreline jurisdiction; however, whether an environmentally critical area is
within shoreline jurisdiction shall be determined by the shoreline administrator. No
action shall be taken by any person that results in any alteration of any
environmentally critical area or their buffers except as consistent with the purposes,
objectives, and goals of this chapter.
Section 7. Arlington Municipal Code Sections 20.93.500 through 20.93.540 shall
be and hereby are repealed in their entirety.
Section 8. Arlington Municipal Code Section 20.93.620 shall be and hereby is
amended to read as follows:
20.93.620 - Allowed activities. Except where regulated by other sections of this or
any other title or law, the following uses shall be allowed within geologically
hazardous areas when the requirements of Section 20.93.630 (Geologically Hazardous
Areas—Requirements) have been met and mitigation adequate to alleviate any other
impacts has been proposed:
(a) Those activities allowed per Section 20.93.220 (General Provisions—
Allowed activities).
(b) Any other use allowed per the zone, and Shoreline Master Program,
provided that it meets the requirements of Section 20.93.630 (Geologically Hazardous
ORDINANCE No. 2016-XXX 4
Areas—Requirements) and will not have a detrimental impact on the health, safety,
and welfare of the public, or will not negatively impact neighboring properties.
(c) Recontouring of land to eliminate geologically hazardous areas,
including steep slopes, is expressly prohibited unless otherwise approved through the
land use permit process (not the construction plan review process). The permit issuing
authority may approve recontouring to eliminate geological hazardous areas only upon
finding that such action would serve the health, safety, and welfare of the general
public and not just a particular development proposal.
Section 9. Arlington Municipal Code Section 20.93.630(a) shall be and hereby is
amended to read as follows:
a) Erosion hazard areas. All development proposals on sites containing erosion
hazard areas shall comply with the following requirements:
(1) Erosion control plan. The applicant shall submit an erosion control plan
prior to the approval of any permit. Plans shall be consistent with the guidelines set
forth in the Uniform International Building Code (U IBC) grading section and the
department of public works' construction standards and specifications.
(2) Alteration. All authorized clearing for roads, utilities, etc., shall be
limited to the minimum necessary to accomplish the engineering design. Alterations of
erosion hazard sites shall meet the requirements of AMC Chapter 20.44, Part II (Land
Clearing, Grading, Filling, and Excavation).

be in accordance with the provisions in the IBC, as adopted by the cCity of Arlington.
Section 11. Arlington Municipal Code Section 20.93.640 shall be and hereby is
amended to read as follows:
20.93.640 - Mitigation. If potential geologic impacts cannot be avoided by adhering to
the above requirements, other forms of mitigation may be considered. Applicants must
provide mitigation plans exploring and analyzing any proposed mitigation measures.
What is considered adequate mitigation will depend on the nature and magnitude of
the potential impact. to the Shoreline and an ecological function. For example, some
potential risk due to construction in geologically hazardous areas may be reduced
through retention of existing vegetation.
ORDINANCE No. 2016-XXX 5
Section 12. Arlington Municipal Code Section 20.93.800 shall be and hereby is
amended to read as follows:
20.93.800 - Classification.
(a) Wetlands shall be rated according to the Washington State Wetland Rating
System for Western Washington—Revised, Ecology Publication #14-06-029 04-06-
025 or as revised by ecology Ecology. Wetland rating categories shall be applied as the
wetland exists at the time of the adoption of this title or as it exists at the time of an
associated permit application. Wetland rating categories shall not change due to illegal
modifications. Wetlands identified as having local significance in hydrologic and
habitat functions may be rated higher based on importance.
(b) Wetland types.
(1) Category I. Category I wetlands are:
(A) Relatively undisturbed estuarine wetlands larger than one acre;
(B) Wetlands that are identified by scientists of the Washington
Natural Heritage Program/DNR as high quality wetlands of high
conservation value;
(C) Bogs;
(D) Mature and old-growth forested wetlands larger than one acre;
(E) Wetlands in coastal lagoons; or
(F) Wetlands that perform many functions well and score seventy 23
or above.
Category I wetlands represent a unique or rare wetland type, are more
sensitive to disturbance than most wetlands, are relatively undisturbed
and contain some ecological attributes that are impossible to replace
within a human lifetime, or provide a very high level of functions.
(2) Category II. Category II wetlands are:
(A) Estuarine wetlands smaller than one acre, or disturbed estuarine
wetlands larger than one acre;
(B) A wetland identified by the Washington State Department of
Natural Resources as containing "sensitive" plant species;
(C) A bog between one-fourth; and one-half; acre in size;
(D) An interdunal wetland larger than one acre; or
(BE) Wetlands with a moderately high level of functions,
(F) Wetland scoring between fifty-one 20 and sixty-nine 22 points;
(G) Wetlands identified as having local significance in reducing
flooding or providing habitat.
Category II wetlands are difficult, though not impossible, to replace, and provide high
levels of some functions. These wetlands occur more commonly than Category I
wetlands, but they still need a relatively high level of protection.
(3) Category III. Category III wetlands are:
(A) Wetlands with a moderate level of functions scoring between
thirty 16 and fifty 19 points; or that can be adequately replaced with a
well-planned mitigation project.
ORDINANCE No. 2016-XXX 6
(B) Interdunal wetlands between 0.1 and one acre in size. Generally,
wetlands in this category may have been disturbed in some way and are
often less diverse or more isolated from other natural resources in the
landscape than Category II wetlands.
(4) Category IV. Category IV wetlands have the lowest levels of functions
scoring less than thirty 16 points and are often heavily disturbed. These are
wetlands that should be replaceable, and in some cases may be improved.
However, experience has shown that replacement cannot be guaranteed in any
specific case. These wetlands may provide some important functions and
should be protected to some degree.
Section 13. The first paragraph of Arlington Municipal Code Section 20.93.820
shall be and hereby is amended to read as follows:
Except where regulated by other sections of this, Shoreline Master Program or any
other title or law, and provided they are conducted using best management practices,
the following uses shall be allowed within wetlands and their buffers when the
requirements of Sections 20.93.830 (Wetlands—Requirements) and 20.93.840
(Wetlands—Mitigation) have been met, state and federal approvals have been granted
when required, and mitigation adequate to alleviate any other impacts has been
proposed:
Section 14. Arlington Municipal Code Section 20.93.820(g) shall be and hereby is
amended to read as follows:
(G) Stormwater management facilities. Stormwater management facilities are
limited to stormwater dispersion outfalls and bioswales. They may be allowed within
the outer twenty-five percent of fifty-foot management zone, whichever is most
protective, of Category II, III or IV wetlands buffers when the fifty-foot management
zone is in an already developed state including buildings, parking lots, lawn or
ornamental landscaping stormwater management systems designed to blend into the
natural landscape allowing full mature growth of native trees and shrubs, and provide
the same or greater functional habitat that would occur in a naturally vegetated buffer.
Specifically, this does not include buried vaults, ecology block or grass-lined ponds or
swales (though ponds or swales planted with native vegetation may be allowed). Such
systems are required to provide diffuse effluent point(s) to the immediate edge of the
no-touch buffer to allow infiltration and polishing, provided that:
(i) No other location is feasible; and
(ii) The location of such facilities will not degrade the functions or values
of the wetland; and
(iii) Stormwater management facilities are not allowed in intact buffers of
Category I wetlands.

DESCRIPTION:
The Permissible Use Table was amended to only allow self-storage unit facilities
within General and Light Industrial Zoned areas of the city during the Comprehensive
Plan update. The AMC does not address Self-Storage Facilities and the different
variations but rather combines all forms of storage into one use. Staff and the
Planning Commission have identified the need to differentiate between typical self-
storage facilities and the professional, more modern versions that could be beneficial
as part of the mixed use concept and provide a useful service in proximity of high-
density residential developments. Several meetings (workshops) with the Planning
Commission were held, and a Noticed Public Hearing was conducted on July 7, 2016.
The Planning Commission Findings of Facts will be prepared as part of the Ordinance
adoption.

HISTORY:
The current adopted version of storage facilities reflects an early form of self-storage,
often called a “mini-warehouse” – a group of small, one-story metal buildings with
numerous overhead doors opening to a grid of asphalt driveways and surrounded by
chain link fence. These facilities resemble other industrial uses and it made sense to
allow them only in these zones. Changes in urban households have led to a different
market for residential storage. The result is a building form that is very different from
the earlier style of the “mini-warehouse”. Modern self-storage facilities include multi-
story buildings with a single store front entry and an exterior appearance that more
resembles a professional office building. Because of their architectural treatments,
these facilities can be compatible with more varied settings in commercial areas that
are convenient to high-density residential areas where most customers would
originate, reducing the need to travel long distances, thus reducing traffic and the
carbon footprint. PSRC recently identified that our Comprehensive Plan lacked
policies that addressed this concern.

Discussion Items for Storage Facilities
Background:
The City of Arlington's Land Use Code does not specifically contain a definition of "self-- storage",
"storage", or "mini-warehouse" facilities, but rather combines all forms of storage, other than
automobiles, aircraft, and hazardous materials, in section 10.000 of the Title 20 table of permissible
uses (20.40.010-1). In July and August of 2015, the Planning Commission held numerous public
workshops and an open record public hearing for the purpose of updating the Table of Permissible
Uses. The Commission subsequently recommended passage of a package of updates to this
section. Among other changes, the recommendations included removal of self-storage facilities from
the Highway Commercial Zone, limiting these uses to our General and Light Industrial zones.
On October 5th, 2015 Council voted to update the AMC, Section 20.40.010, Table of Permissible
Uses, following the Planning Commission's recommendations.
No specific design standards or parking and loading standards currently exist for the use "storage".
There is also no distinction made between storage in rented space and storage in privately owned
space, such as garages, storage sheds, or containers located on private residential property.
The City currently has a permit application for a proposed modern style storage facility to locate in
the Highway Commercial zone. Under the current code, this location would not be allowed.
Issue:
The adopted treatment of storage unit location reflects an early form of self-storage, often called a
"mini-warehouse" facility that consists of a group of small, one-story metal buildings with numerous
overhead doors opening to a grid of asphalt driveways ringed by chain link fence and often including
accessory outdoor storage yards. These facilities are often regulated to industrial districts because
they resembled other one- story metal buildings that are common in industrial districts or rural
highway corridors. We have several examples of these early storage facilities in Arlington and North
Marysville.
Changes in urban households have led to a different market for residential storage. The result is a
building form that is very different from the earlier style of "mini-warehouses".
Modern self-storage facilities include multi-story buildings with a single storefront entry and an exterior
appearance and architectural features resembling a multi-story office building. These buildings feature
elevators, internal corridors accessing storage spaces of various sizes and concealing the roll-up doors.
Most, if not all of the self-storage units are climate-controlled. There does not need to be outdoor
storage or large loading docks. In some cases, there are fenestrated exterior access corridors that are
day- lighted.
Because of their architectural treatments, these facilities can be compatible with more varied settings in
commercial areas that are convenient to high-density residential areas where most customers originate,
creating an opportunity for residential customers to not have to drive back and forth to storage facilities.
Thus reducing traffic, emissions and carbon footprint. PSRC recently identified that our Comprehensive
Plan lacked policies that addressed these concerns.
1
Staff is bringing this matter to the Planning Commission to reconsider the treatment of this type of self-
storage facility by taking a finer grained look at the location and design of a variety of storage
configurations and perhaps allowing the more contemporary multi-story self-storage buildings with
interior access to be permitted in Arlington's Highway Commercial zones and possibly in the mixed-use
overlay zones. In addition, staff is requesting that some differentiation be established between
commercial and private storage activity.
Recommended Actions – Phase I:
1. Staff recommends amending AMC Section 20.40.010, Table of Permissible Uses 20.40-1 as follows:
10.210 Multi-Storied, Self-Storage Facility (as described in Section 20.08.010 Definitions) to be permitted
in the Highway Commercial, Light Industrial, and General Industrial zones.
10.220 Self-storage facility (as described in Section 20.08.010 Definitions) to be permitted in Light
industrial and General Industrial zones.
10.230 Warehouse storage facility (as described in Section 20.08.010 Definitions) to be permitted in Light
Industrial and General Industrial zones.
2. Staff recommends amending AMC Section 20.08.010, Basic Definitions and Interpretations as
follows:
Multi-Storied Self-Storage Facility, - a type of multi-story self-storage use that provides climate
controlled space for interior units. With no individual storage exceeding 300sf. Storage to consist of
personal property of household and small businesses. A minimum of 35% approved glazing required on
front façade. A minimum of 1,000sf shall be utilized as office/retail on ground floor. Shall provide either 24-
