In 1990, the Washington Legislature enacted the Growth Management Act (GMA)
to counteract problems related to unmanaged population growth. The GMA fun
damentally altered two traditional aspects of land use law: the disregard f
or planning documents and the aversion to mixing uses within zones. Countie
s and cities planning under the Act now must have comprehensive plans and z
oning ordinances that are consistent with those plans. They are also encour
aged to use innovative zoning tools such as mixed-use housing developments.
In the 1997 case Citizens for Mount Vernon v. City of Mount Vernon, the Su
preme Court of Washington applied pre-GMA common law to decide the effect o
f comprehensive plans on specific land use decisions. It held that zoning o
rdinances supersede inconsistent comprehensive plans in such decisions. Thi
s Note analyzes Mount Vernon and concludes that the Supreme Court of Washin
gton needlessly clung to pre-GMA notions that avoid planning and mixed-use
zoning in residential districts. This Note recommends that the court abando
n pre-GMA case law in future land use cases and consider bifurcating the st
andard of judicial review of land use cases.
