15.600.005 Purpose

A.    This chapter shall be known as the SeaTac Sign Code, may be cited as such, and will be referred to herein as “this code.”

B.    The purpose and scope of this code is to protect the health, safety, property and welfare of the citizens of the City of SeaTac (hereafter “City”), by establishing standards for the design, placement, size and maintenance of all signs and sign structures in the City. Furthermore, it is the purpose of the regulations, standards and criteria of this code to permit and encourage the design of signs which are responsive to the needs of the public in locating a business establishment by identification, address and product and/or services information.

C.    This code aims to address emerging trends in electronic message sign technologies and provide regulations that facilitate the use of such technologies while ensuring protection of motorists and pedestrians from the hazards of glare, startling bursts of light, and the use of virtual movement and animation intended to attract driver attention, to hold driver gaze, and/or to otherwise distract drivers from the safe operation of their vehicles. The code’s intent is to protect neighborhoods, surrounding development and the night sky from nuisance factors associated with such glare, movement and animation of electronic message signs.

D.    This chapter is not intended to and shall not be interpreted to restrict noncommercial speech on the basis of its content, viewpoint, or message. No part of this chapter shall be construed to favor commercial speech over noncommercial speech. (Ord. 24-1008 § 1; Ord. 15-1018 § 1)

15.600.010 Authority, Application and Exemptions

A.    The provisions of this chapter shall apply to all signs within the jurisdictional limits of the City, regardless of the type or nature.

B.    Permits shall be required of all signs nine (9) square feet or greater in surface area, and illuminated or electronic signs of any size. Nonilluminated signs less than nine (9) square feet in surface area are not required to obtain a permit, but must meet all requirements of this code.

C.    Any classification of signs in this chapter which purports to permit commercial speech by reason of its content or identity of the sign user, or otherwise, shall be interpreted to allow noncommercial speech on the sign.

D.    To the extent that any provision of this chapter is ambiguous, the term shall be interpreted not to regulate speech on the basis of the content of the message.

E.    All signs not specifically defined and allowed or exempted by this code are prohibited.

F.    The following are exempted from the regulations and requirements of this chapter, but may be subject to regulation under other provisions of the SMC:

B.    Applicability. This section applies to each application for a variance from the provisions of the Sign Code.

C.    Purpose. A variance is a mechanism by which the City may grant relief from the provisions of the Sign Code where practical difficulty renders compliance with the provisions of that code an unnecessary hardship, where the hardship is a result of the physical characteristics of the subject property and where the purpose of that code can be fulfilled.

D.    Who May Apply. The property owner may apply for a variance from the provisions of the Sign Code.

E.    Submittal Requirements.

1.    The Administrator shall specify the submittal requirements including type, detail and number of copies for a variance application to be deemed complete and accepted for filing.

2.    The Administrator may waive specific submittal requirements determined to be unnecessary for review of an application.

F.    Decision Criteria. The Hearing Examiner may approve or approve with modification the application for a variance from the provisions of the Sign Code if:

1.    The variance will not constitute a grant of special privilege inconsistent with the limitation upon signage and uses of other properties in the vicinity and zone in which the property, on behalf of which the application was filed, is located; and

2.    That the granting of such variance will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity and in the zone in which the subject property is situated; and

3.    The proposed sign shows an exceptional effort toward creating visual harmony between the signs, structures, and other features of the property through the use of a consistent design theme; and

4.    The special circumstances of the subject property are not the result of the actions of the applicant.

G.    Limitation of Authority. The Hearing Examiner may not grant a variance to:

1.    Any dimensional request of the Sign Code greater than fifty percent (50%) of the required dimension of a sign (setbacks from a property line shall not be deemed a dimensional standard of sign); or

2.    The number of signs permitted on a site or zone classification; or

3.    The general provisions of this code or any other procedural or administrative provisions of the code that do not directly apply to this chapter; or

4.    The provisions of the Sign Code which are not subject to variances shall include, by the terms of this code, type of signs and any prohibited or illegal signs, and the dimensional standards of the changeable portion of an electronic sign;

5.    Roof Signs. Notwithstanding SMC 15.600.090, Prohibited Signs, a roof sign may be allowed through a variance process provided the following criteria are met in addition to the decision criteria listed under subsection (F) of this section:

a.    The site does not front on any street and is more than two hundred (200) feet from a public right-of-way;

b.    The sign is no greater than necessary for adequate visibility from the nearest public street. Adequate visibility shall be determined by the size of sign allowed in the subject zone, plus a factor for distance from the nearest public street;

c.    No other permanent signage exists or shall be allowed for the site;

d.    The sign is installed in such a manner that there shall be no visible support structure;

6.    Off-Premises Signs. Notwithstanding SMC 15.600.090, Prohibited Signs, an off-premises sign may be allowed through a variance process provided the following criteria are met in addition to the decision criteria listed under subsection (F) of this section:

a.    For a permanent sign:

i.    Permanent signage cannot be located on the site.

ii.    The sign displays only information directly related to the use of property of the subject business or property for which the variance is granted.

iii.    The sign is located as close as possible to the subject business or property.

b.    For a directional sign:

i.    The applicant demonstrates that his premises are located such that on-premises directional signs are inadequate to reasonably apprise the public of the location of the premises, because the premises lacks any direct street frontage.

H.    Time Limitation. A variance automatically expires and is void if the applicant fails to file for a sign permit or other necessary development permits within two (2) years of the effective date of the variance unless:

1.    The applicant has received an extension pursuant to subsection (I) of this section; or

2.    The variance approval provides for a greater time period due to circumstances.

I.    Extension.

1.    The Code Administrator may extend a variance, not to exceed one (1) year, if:

a.    Unforeseen circumstances or conditions necessitate the extension of the variance; and

b.    Termination of the variance would result in unreasonable hardship to the applicant, and the applicant is not directly responsible for the delay; and

c.    The extension of the variance will not cause substantial detriment to existing uses in the immediate vicinity of the subject property.

2.    The Administrator may grant no more than two (2) extensions. A second extension may be granted if:

a.    Unforeseen circumstances or conditions necessitate the extension of the variance;

b.    The applicant has demonstrated reasonable diligence in attempting to meet the time limit imposed;

c.    Conditions in the immediate vicinity of the subject property have not changed substantially since the variance was first granted.
