   Just after midnight on October 26, 2004, the King County (1) Council approved Ordinance 15053, (2) a controversial clearing and grading ordinance characterized by property rights advocates, and certain members of the council, as the "most restrictive land use law in the nation." (3) Passed by a vote of 7-6, the ordinance imposes stringent land clearing restrictions on King County's rural landowners because a majority of the council concluded, on the basis of extensive scientific studies, that excessive clearing and loss of forest cover causes significant damage to wetlands, streams, and groundwater. Specifically, the studies showed that substantial impairment to water quality results when more than 35% of a watershed is cleared, (4) and that potentially irreversible loss of aquatic system function occurs where more than 10% is covered with an impervious surface. (5)

   Ordinance 15053 prohibits most rural landowners in unincorporated King County from clearing more than 50% of their land. (6) Owners of large land parcels (parcels greater than five acres) are prohibited from clearing more than 35% of their land. (7) The remaining 65% of the land must remain unaltered in its natural forested or vegetative condition. These clearing restrictions became effective on January 1, 2005.

   King County adopted the new clearing and grading ordinance in response to Washington's Growth Management Act (GMA), (8) which requires cities and counties to adopt and periodically update regulations that protect critical areas. (9) The GMA established a timetable for critical area regulation updates, requiring King County to review and revise its existing regulations by December 1, 2004. (10) By December 1, 2007, every other city and county in Washington must review and update their critical area regulations. (11)

   In March 2005, Pierce County, which borders King County to the south, became the second county in Washington to prohibit rural residential landowners from clearing more than 35% of their land. (12) With thirty more counties required to update their critical area regulations by December 1, 2007, other counties may follow King County's lead and enact similarly restrictive clearing regulations. The success or failure of legal challenges to the King County ordinance will likely influence whether other counties adopt similar regulations. (13)

   Affected rural landowners in King County claim that the land clearing restrictions are an unconstitutional intrusion on their private property rights. (14) There are two primary avenues to challenge the constitutionality of a land-use regulation in Washington. (15) The first is to allege that the regulation has "taken" the landowner's property without payment of just compensation in violation of the Fifth Amendment of the U.S. Constitution. (16) The second is to argue that the regulation violates the landowner's substantive due process rights under the Fourteenth Amendment (17) of the U.S. Constitution. (18) A landowner could also argue that the regulation takes property in violation of article I, section 16 of the Washington Constitution. (19) However, with only one exception, the Washington Supreme Court has not interpreted the takings clause in Washington's Constitution to provide broader protection than the Fifth Amendment. (20)

   It is unlikely that any landowner can successfully claim, either in a facial or as-applied challenge, under either the U.S. or Washington Constitution, that Ordinance 15053 amounts to a regulatory taking because the ordinance substantially advances the county's interest in water quality protection, does not destroy fundamental attributes of property ownership, and will not have a sufficiently adverse economic effect on landowners to amount to an unlawful taking. (21) Landowners can still possess, convey, build on, and subdivide their land and thus retain a significant amount of economic value in their land. (22) The county's interest in protecting the quality of ground and surface water from the harm that results from loss of forest cover, as shown by the scientific studies that the county relied upon, is also significant. (23) Since Washington courts rarely conclude that land-use regulations take private property, the success of a takings claim seems especially unlikely. (24)

   On the other hand, the Washington Supreme Court has exhibited a willingness to rule that restrictive land-use regulations violate a landowner's federal Substantive due process rights. (25) The different remedies that the two claims offer explain this preference for due process versus takings analysis. A successful takings claim requires the local government to fully compensate the landowner, even for a temporary taking, (26) but a successful due process claim only results in invalidation of the ordinance. (27) The court expressly prefers the remedy of invalidation over an award of damages for burdensome land-use regulations, because the "specter of strict financial liability" in takings cases results in a "chilling effect" on land-use regulation, deterring legislative bodies from malting difficult land-use regulatory decisions. (28)

   The Washington Supreme Court's substantive due process analysis of land-use regulation poses a more significant and less predictable hurdle for the King County ordinance, primarily due to the large amount of discretion that the due process test vests in the court. (29) Washington's Supreme Court determines whether an ordinance violates federal due process rights by balancing numerous factors that weigh in favor and against the public and private interests involved. (30) The key inquiry in the context of the clearing and grading ordinance is whether the 35 and/or 50% clearing limits are "unduly oppressive" to individual landowners in rural King County. (31)

   This Comment analyzes the constitutionality of the clearing and grading restrictions adopted by King County in Ordinance 15053. Part II scrutinizes the key provisions of Ordinance 15053 and the justifications for their adoption. Part III explains why landowners will likely fail on their claims that the ordinance works a regulatory taking of their land. Part IV examines the Washington Supreme Court's application of substantive due process and argues that Ordinance 15053 does not violate the substantive due process rights of King County's rural landowners. The Comment concludes that Washington courts will likely hold that Ordinance 15053 neither unconstitutionally takes private property, nor violates landowners' substantive due process rights because of the county's substantial interest in protecting water quality, and because the economic impact on affected landowners is insufficient to result in a taking or a due process violation.

2. KING COUNTY ORDINANCE 15053: RESTRICTIONS ON CLEARING TO PREVENT HARM TO WATER QUALITY AND SPECIES

   The GMA requires every city and county in Washington to designate critical areas within their jurisdiction and to protect those areas through the adoption of development regulations. (32) Critical area regulations serve a dual purpose of protecting both public health and safety and environmentally sensitive areas. Critical area regulations comply with the GMA only if they include the best available scientific information and protect all "functions and values" of the critical areas designated by the local government. (33) In developing critical area regulations, local governments must give special consideration to the conservation and protection of anadromous fisheries within the government's jurisdiction. (34)

   In late 2002, King County began to review the existing science on critical area protection in preparation for its required critical area regulation updates. In February 2004, the county published a two-volume report that summarized the best available scientific information and assessed the new critical area protections that King County proposed. (35) In October 2004, after two full years of scientific review, twenty-one public meetings, and sixteen opportunities for public comment, the King County Council narrowly approved a "critical areas package" that included a stormwater ordinance, a critical areas ordinance, and, most controversially, Ordinance 15053, the clearing and grading ordinance. (36)

   The purpose of the new clearing limits is to preserve the quality of streams and groundwater and protect anadromous fish habitat through retention of adequate forest cover (37) King County relied on...
