The states of California and Nevada established the Tahoe Regional Planning Agency (TRPA) to study the impact of development on Lake Tahoe. The TRPA imposed two moratoria beginning in 1981, totaling 32 months, on development in the Lake Tahoe Basin while formulating a comprehensive land-use plan for the area. In 1984 the TRPA adopted a new and comprehensive land-use plan. Plaintiffs, real estate owners impacted by the moratoria and an association representing area landowners, filed suits claiming that TRPA's actions constituted a taking of their property without just compensation. Explain whether the moratoria imposed an illegal taking.
