Waterfront redevelopment in the Northeast United States often involves former industrial sites, many of which are contaminated (brownfields). Option A (include brownfield remediation strategies) is correct, as these plans typically require cleanup to make the land safe for new uses like housing or recreation. The APA’sAICP Certification Exam Content Outline(2022), under “Areas of Practice,” states, “Waterfront redevelopment in the Northeast frequently involves brownfield remediation due to historical industrial activity.” Option B (not addressing water’s edge ecology) is incorrect, as ecological restoration is a key component. Option C (new industrial employment) is unlikely, as modern waterfront plans often focus on mixed-use or recreational development. Option D (no federal involvement) is incorrect, as agencies like the EPA or Army Corps of Engineers are often involved due to environmental and waterway regulations. TheCPC Study Manual(2024) notes, “Northeast waterfront redevelopment typically requires brownfield remediation to address contamination from past industrial use,” supporting option A.

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.

Social media surveys are prone to selection bias, as the sample may not represent the broader population—social media users skew younger and may exclude non-users (e.g., elderly, low-income groups). Option A (selection bias) is the most important to address. The APA’sAICP Certification Exam Content Outline(2022), under “Research and Assessment Methods,” states, “Selection bias is the most critical concern in social media surveys, as the platform’s user base may not reflect the general population.” Option B (non-response bias) is a concern but less dominant than selection bias in this context. Option C (framing bias) relates to question wording, not the platform. Option D (decision-making bias) is unrelated to survey design. TheCPC Study Manual(2024) confirms, “Social media surveys primarily face selection bias due to unrepresentative user demographics,” supporting option A.

The city council’s directive to “limit or reduce energy use by the city and its residents” focuses on a broad goal of energy reduction across the entire community. Option D (need to reduce energy use throughout the city) best reflects this comprehensive objective. The APA’sAICP Certification Exam Content Outline(2022), under “Plan and Policy Development,” states, “When addressing energy concerns, the goal should encompass reducing energy use citywide, covering both municipal and resident consumption.” Option A (residents’ concerns) is a motivation, not the goal. Option B (bus ridership) is a specific strategy, not the goal. Option C (municipal expenditures) is too narrow, as the directive includes residents. TheCPC Study Manual(2024) confirms, “The goal of reducing energy use should address both city and resident consumption, focusing on the entire community,” supporting option D.
