Supreme Court Rules on Traffic Mitigation Fees in California

Courtroom scene related to traffic mitigation fee ruling

California, August 31, 2025

News Summary

The U.S. Supreme Court has issued a unanimous ruling on the legitimacy of traffic mitigation fees, affirming that such fees are subject to constitutional scrutiny under the Takings Clause. This decision emerged from a case involving a $23,420 fee imposed by El Dorado County, which an engineer challenged after paying it under protest. The ruling emphasizes the need for local governments to justify fee structures, potentially reshaping how municipalities across California approach development impact fees and land-use regulations.

California – In a significant ruling, the U.S. Supreme Court has addressed a contentious issue involving the legitimacy of traffic mitigation fees imposed by local governments, specifically focusing on a $23,420 fee from El Dorado County. The court’s unanimous decision on April 12, 2024, reaffirmed that legislatively imposed development impact fees are not exempt from scrutiny under the Takings Clause of the Fifth Amendment. This ruling emerged from the case of George Sheetz, an engineer who, after paying the fee under protest, challenged its legality through various court venues.

Sheetz had applied for a county permit nearly a decade ago, seeking to place a manufactured home on his property situated in rural El Dorado County. The county’s requirement for the payment of a substantial traffic mitigation fee was intended to address what local officials suggested would be increased traffic from the new dwellings. This fee structure was established under a general plan adopted in 2004 and later amended in 2006, which emphasized the establishment of traffic mitigation fees associated with building permits.

Initially, Sheetz’s challenge was dismissed by the trial court, which maintained that the mitigation fees implemented by legislative action were not subject to scrutiny under California’s Mitigation Fee Act. Following this, a California appellate court upheld the legality of the fees in 2022. When the California Supreme Court declined to hear Sheetz’s case, it was escalated to the U.S. Supreme Court, leading to the recent landmark decision.

The Supreme Court ruled that the obligation of both legislatures and agencies to avoid imposing unconstitutional conditions extends to development impact fees. This ruling nullified the previous assumption that such fees could not be scrutinized as per the Mitigation Fee Act’s standards. Consequently, the California courts were instructed to continue proceedings related to the case, integrating the Supreme Court’s guidance.

Despite the Supreme Court’s pronouncement, the California appellate court has recently reaffirmed the enforcement of the $23,420 traffic mitigation fee. The court concluded that the fee had a definitive link to the county’s vested interest in managing traffic congestion created by new construction. Employing the established “Nollan/Dolan” tests to analyze the proportionality of the fee against Sheetz’s property development, the court found that the conditions set forth were justified.

The ruling has faced criticism from various stakeholders. Advocates, including representatives from the Pacific Legal Foundation, have labeled the fee as an inappropriate financial demand resembling an “exorbitant ransom” for permission to build. Despite this pushback, the court’s decision indicates that while development impact fees must continue to align with constitutional scrutiny, they can still be upheld if grounded in relevant data and methodology.

This recent ruling is poised to affect how municipalities across California approach the establishment and enforcement of impact fees and land-use regulations. Observers with an interest in local governance and development policies are encouraged to monitor future legal challenges related to legislative impact fees, as the implications of the Sheetz case are likely to resonate through various jurisdictions.

Key Takeaways from the Supreme Court Ruling

  • The ruling asserts that legislatively imposed traffic mitigation fees are subject to constitutional evaluation.
  • Local governments must demonstrate a clear nexus and proportionality in fees associated with development projects.
  • Ongoing legal challenges may reshape the landscape of development impact fees in California.
