BACKGROUND
DISCUSSION
City of Tukwila
INFORMATIONAL MEMORANDUM
Jim Haggerton, Mayor
Should we treat noise received by residential uses in commercial and industrial districts differently
that we treat noise received by residential uses in residential districts? Should we limit some noises
created in commercial and industrial districts when a residential use occurs in that district?
The proposed noise ordinance went to Community Affairs and Parks on April 12, 2010. During the
public hearing, Council heard testimony from several citizens.
At the May 3, 2010 Regular Meeting, Vanessa Zaputil reiterated her testimony and requested
Council consider more stringent requirements to protect residential uses in commercial or industrial
zones throughout the city, particularly from construction equipment, maintenance noises and other
routine noises. She also requested noticing for noise events. The Council requested to see a map
that highlights areas where residential uses exist in non residential zones. Council further requested
that staff return to the Community Affairs and Parks Committee to review available options for
addressing these concerns.
State law sets standards that residents in residential districts are to be protected from unreasonable
noises, particularly during nighttime hours when most are sleeping and when the ambient noise level
is naturally reduced. State law and the current noise code also specifically exempt construction
noise from nighttime limits in non residential districts. The proposed ordinance follows the WAC by
allowing commercial and industrial activity to continue at night provided that noise from such activity
does not spill over into residential districts. The proposed ordinance also exempts property
maintenance noise within non residential districts while prohibiting those same noises from being
received at night in residential districts. See Attachment A for a comparison between the proposed
ordinance, the current code and the WAC.
Non residential zones are principally for commercial and industrial uses which are noisier than
residential uses. The map, provided as Attachment B, shows identifiable residential uses located in
commercial or industrial zones. Tukwila's zoning code allows some form of residential use in every
zone in the City. These residential uses range from single family dwellings to mixed -use buildings in
commercial zones to caretaker homes on industrial properties. While the data is very limited, there
are 88 identified residential units in non residential zones. Of these 88 units, 48 are non conforming
residential uses.
In the 12 months ending April 10, 2010, the City received 517 noise complaints through the police
department. None of these complaints were for construction, highway construction or property
maintenance noise that would be exempt under the new code. The new code adds an allowance
for the Director to require noise abatement even for exempt sounds.
INFORMATIONAL MEMO
Page 2
Per the WAC, the proposed ordinance does not require a variance for highway construction noise in
non residential zones and allows any noise variance up to 30 days in residential zones to be granted
without notice. If variances and noticing of variance requests were to be required in all zones and
for all time frames, applicant expense and staff time for variance requests would increase and the
noticing provided for highway construction variance requests often occurs weeks or months before
the actual noise generating event. Staff suggests an option to provide applicable notice at the onset
of highway construction noise while not increasing the need for variances and a condition that
variances granted more than 30 days before the noise event occurs include residential notice at the
onset of the noise event.
The proposed ordinance reduces staff time for processing variances, allows the status quo to
continue regarding construction noise at night, is simple to enforce and allows the Director to require
noise abatement for all sounds. However, the proposed ordinance could be amended to remove
the exemptions for property construction noises, highway construction noises, noticing requirements,
and /or property maintenance noises (see Attachment C for possible ordinance changes). The pros
and cons of these options are detailed below.
Issue 1: Remove property construction exemption
The current code, the proposed ordinance, and the WAC all exempt nighttime construction noises in
commercial and industrial districts. If the ordinance were to remove this exemption and apply the
"plainly audible" standard to noise sensitive units in all zones for construction related noises, then it
would be possible for the residence located next to Boeing in the MIC /H zone to cause Boeing to
have to cease building construction during nighttime hours. The Segale property could violate the
noise ordinance if nighttime construction noise is received by the security residence on that property.
In Option 1, existing nighttime construction practices may become violations unless a variance is
granted. Variances would increase staff time and applicant expense and would be granted without
notice when noise events are less than 30 days. Noise is not a vested right so the introduction of
new residential uses could cause existing commercial and industrial -zoned properties to become
noise violators. Residential uses in non residential zones could still experience nighttime property
construction noise if a variance is granted.
The City of Kirkland and City of Tacoma prohibit all property construction noise during nighttime
hours. The WAC and Tukwila's current code exempt property construction noise in commercial and
industrial districts but prohibit it where it impacts residential -zoned districts.
Issue 2: Remove hiahwav construction exemption
One of the principal goals of rewriting the noise code was to eliminate the need for variances and
noticing for highway work conducted during nighttime hours in non residential zones. Highway
maintenance variances involve significant staff time and will cost the applicant fees while the
variances granted in the last 3 years have not generated any complaints in Tukwila. Due to the life
safety issues regarding highway construction, nighttime highway construction variances will continue
to be granted. (The requirement for highway maintenance variances in the existing code was due to
a phrasing error and not likely the intent of the code.) Frequently, WSDOT construction noise is no
louder than the ambient noise from the freeway.
The WAC exempts highway maintenance noise at night in commercial and industrial districts.
Issue 3: As a condition of any variance and for any nighttime hiahway maintenance noise, reauire
noticina at the onset of the actual noise- oeneratina event
Noticing of noise variance requests often occur well before a project begins. The noticing is
provided to alert citizens of the variance request and may or may not provide timely notice of when
the actual construction will occur. Further, the proposed ordinance provides relief from noticing
requirements for variances Tess than 30 days and does not require a variance for highway

construction noise in non residential zones. Adding a requirement for noticing at the onset of
highway construction and as a condition of all variance requests provides residences an awareness
of impending activity and an opportunity to plan accordingly.
Noticing would only occur for residential uses and can be provided by mail or by door hangers; it
would be similar to the noticing requirements added to residential parties at the CAP meeting on
April 12, 2010. Noticing at the onset of events will also be required of City- sponsored projects which
will increase staff time. Noise generating events are often weather dependant and span a significant
length of time; noticing at the onset may not sufficiently prepare residents for the entirety of the
actual noise occurrences.
Issue 4: Remove ororerty maintenance exemption
The new code introduces an exemption for nighttime property maintenance. It is reasonable to
expect commercial and industrial uses to use maintenance equipment during nighttime hours to
prepare for daytime operations but no complaints for nighttime property maintenance have been
received. Removing this exemption would mirror the existing noise code by maintaining a violation if
citizens located in non residential zones are exposed to nighttime property maintenance noise from
commercial and industrial properties. Variances could still be sought. Removing this exemption
would make nighttime property maintenance noises subject to the "plainly audible" standard of the
new code.
The City of Kirkland prohibits property maintenance noise during nighttime hours. The City of
Bellevue exempts property maintenance at night. The WAC only exempts property maintenance
during the day and only from residential properties.
RECOMMENDATION
To balance the concerns of the residential community with the needs of commercial and industrial
uses, staff recommends the following:
Issue 1: Staff recommends no changes to the proposed ordinance and maintaining the construction
exemption;
Issue 2: Staff recommends no changes to the proposed ordinance and maintaining the highway
construction exemption;
Issue 3: Staff recommends requiring noticing at the onset of a noise generating event; and
Issue 4: Staff recommends removing the exemption for nighttime property maintenance from the
proposed ordinance.
Staff recommends forwarding the draft ordinance with the recommended amendments to include
Issues 3 and 4 for consideration to the Committee of the Whole meeting June 28, 2010.
Proposed ordinance changes are included as Attachment C.

New code versus old codes:
Specify Maximum Permissible Sound levels and give options for determining
violations. It is a violation to exceed certain decibel levels based on time of day and
district designations.
Both codes exempt construction noise from temporary construction sites in
commercial and industrial districts at all times.
Both codes exempt highway maintenance noise in commercial and industrial
districts. The old code also exempts highway maintenance noise in residential
districts but because of a language error variances are required for highway
maintenance.
Both codes exempt property maintenance noise in all districts during the day. The
new code also exempts property maintenance noise in commercial and industrial
districts during the night.
Additionally, in the new code,
It is a violation to produce non exempt plainly audible sound that can be heard from
within a noise sensitive unit during the nighttime hours. "Noise Sensitive Unit"
includes residential use in any district.
It is a violation to produce plainly audible commercial music at a distance of 50 feet
from the property line of the commercial establishment.
