Which of these regions is planned, protected, and managed by a bi- or multi-state regional...

The Lake Tahoe region, spanning California and Nevada, is managed by the Tahoe Regional Planning Agency (TRPA), a bi-state agency established in 1969 to oversee land use, environmental protection, and development in the region. The TRPA is a well-known example of a multi-state regional planning body, created through a compact between the two states and approved by Congress. The APA’sAICP Certification Exam Content Outline(2022), under “Areas of Practice,” identifies “Lake Tahoe as a model of bi-state regional planning, managed by the TRPA to protect the lake’s ecosystem and manage growth.” The other regions—Highlands (B), Ozarks (C), and Delmarva Peninsula (D)—do not have similar bi- or multi-state planning agencies. The Highlands region has some regional coordination but not a formal multi-state agency like the TRPA. TheCPC Study Manual(2024) notes, “The TRPA at Lake Tahoe is a leading example of a bi-state planning agency addressing land use and environmental challenges,” supporting option A.
