INTERPRETATION #: CI-143
MUNICIPAL
CODE SECTIONS: RMC 8-7-4 Designation of Zoned Areas
REFERENCE: N/A
SUBJECT: Noise Level Regulations: Designation of Zoned Areas
BACKGROUND: Per WAC 173-60-030, in areas covered by a local zoning ordinance, the
legislative authority of the local government may, by ordinance or
resolution designate Environmental Designations for Noise Abatement
(EDNAs) to conform with the zoning ordinance. This prior designation
replaces the standards outlined in subsection (1), of WAC 173-60-030
with locally adopted designations. RMC 8-7-4 Designation of Zoned Areas
outlines locally designated EDNAs for the City of Renton, but at the time
of adoption did not account for future mixed use development, which
permits multi-family housing in certain commercial zones within the city.
To accommodate mixed use development EDNAs should be revised to
consider use, rather than zoning.
DECISION: Amend RMC 8-7-4 Designation of Zoned Areas to remove prior specific
zoning designations of EDNAs.
JUSTIFICATION: At the time of adoption of RMC 8-7-4 Designation of Zoned Areas, the
zoning code did not permit multi-family development within the City’s
commercial zoned areas. By designating local EDNAs by zone, the City
unintentionally created circumstances where multi-family developments
in commercial zones are not afforded the same noise regulations as
multi-family development in residential zones. This standard is
inconsistent with subsection (1) of WAC 173-60-030, which regulates
EDNAs taking into consideration the present, future, and historical usage,
as well as the usage of adjacent and other lands in the vicinity to
determine appropriate noise levels. To ensure consistency with the State
of Washington and to remedy the discrepancies created by mixed use
structures in commercial zones, the City of Renton proposes to strike the
designation of zoned areas for EDNAs in RMC 8-7-4 and adopt State
CI-143 Page 2 of 2
standards by default, which would result the same noise regulations to
residential uses, and care facilities regardless of zone. Noise impacts are
reviewed within a 300 foot radius of the noise generating source.
