Q1: In 1898, Ebenezer Howard proposed a model for urban development that combined the
benefits of town and country while addressing the overcrowding of industrial cities. What was this
influential concept called?
A. The Radiant City
B. The Garden City [CORRECT]
C. The City Beautiful
D. The Regional Survey
Correct Answer: B
Rationale: The best answer is the Garden City. Howard's 1898 book "Tomorrow: A Peaceful Path to
Real Reform" introduced the Garden City concept, envisioning self-contained, limited-size
communities surrounded by greenbelts. Remember that Howard's Letchworth and Welwyn Garden
Cities in England became the prototypes for this influential planning movement.
Q2: A planning director is reviewing a comprehensive plan update that relies heavily on technical
analysis and expert-driven decision making with limited public input. Which planning theory does
this approach most closely reflect?
A. Advocacy planning
B. Communicative planning
C. Rational comprehensive planning [CORRECT]
,D. Transactive planning
Correct Answer: C
Rationale: The best answer is rational comprehensive planning. This traditional model emphasizes
technical expertise, systematic data analysis, and a top-down, step-by-step approach to identifying
problems, generating alternatives, and selecting optimal solutions. In the Supreme Court case
tradition, rational planning became the standard for justifying zoning decisions, though
contemporary practice has shifted toward more collaborative models.
Q3: Under the U.S. Constitution, which clause provides the primary legal basis for local
governments to enact zoning ordinances and land use regulations?
A. The Commerce Clause
B. The Takings Clause
C. The Police Power [CORRECT]
D. The Supremacy Clause
Correct Answer: C
Rationale: The best answer is police power. State and local governments derive their authority to
regulate land use from the police power—the inherent authority to protect public health, safety,
morals, and general welfare. In the landmark case Euclid v. Ambler Realty Co. (1926), the Supreme
Court upheld zoning as a valid exercise of police power, establishing the constitutional foundation
for modern land use regulation.
Q4: A city council adopts a historic preservation ordinance that restricts alterations to designated
landmark buildings. A property owner claims this regulation constitutes a taking requiring just
compensation. Which Supreme Court test would likely be applied to determine if compensation is
owed?
A. The Euclid test
B. The Penn Central balancing test [CORRECT]
C. The strict scrutiny test
D. The rational basis test
Correct Answer: B
Rationale: The best answer is the Penn Central balancing test. In Penn Central Transportation Co.
v. New York City (1978), the Supreme Court established a multi-factor balancing test that examines
the economic impact on the claimant, the extent to which the regulation interferes with distinct
investment-backed expectations, and the character of the government action. This remains the
primary framework for analyzing regulatory takings claims that don't involve physical invasions or
total wipeouts of value.
,Q5: In the landmark 1922 case Pennsylvania Coal Co. v. Mahon, what key principle did the
Supreme Court establish regarding government regulation of private property?
A. All zoning regulations require compensation
B. Regulations that go too far in diminishing property value constitute a taking [CORRECT]
C. Only physical invasions require just compensation
D. States cannot regulate coal mining operations
Correct Answer: B
Rationale: The best answer is that regulations going too far in diminishing property value constitute
a taking. Justice Holmes famously wrote that while property may be regulated to a certain extent, "if
regulation goes too far it will be recognized as a taking." This case established that regulatory
restrictions—not just physical appropriations—can trigger the Takings Clause of the Fifth
Amendment.
Q6: A religious organization seeks to locate a worship facility in a zoning district that permits similar
secular assembly uses. The local government denies the permit, citing traffic concerns that appear
to be pretextual. Which federal statute provides the strongest protection for the religious
organization?
A. The Religious Freedom Restoration Act
B. RLUIPA [CORRECT]
C. The First Amendment Free Exercise Clause alone
D. The Fair Housing Act
Correct Answer: B
Rationale: The best answer is RLUIPA—the Religious Land Use and Institutionalized Persons Act of
2000. This federal statute prohibits local governments from imposing land use regulations that
impose a substantial burden on religious exercise without a compelling government interest, and it
specifically addresses equal terms treatment and nondiscrimination in land use decisions affecting
religious assemblies.
Q7: Which planning tool allows a local government to designate an area for future development
and apply special zoning standards that will take effect when the area is eventually served by
public facilities?
A. Overlay zone
B. Floating zone [CORRECT]
C. Incentive zoning
D. Conditional use permit
Correct Answer: B
Rationale: The best answer is a floating zone. This innovative zoning tool creates a district that
"floats" across the zoning map without a fixed location until the governing body applies it to a
, specific parcel through a rezoning process. It's particularly useful for planned developments, PUDs,
or special districts that require unique siting considerations and infrastructure timing.
Q8: A rapidly growing county wants to ensure that new development does not proceed faster than
the provision of roads, schools, and water/sewer infrastructure. Which growth management tool
directly ties development approvals to the availability of adequate public facilities?
A. Urban growth boundary
B. Adequate public facilities ordinance (APFO) [CORRECT]
C. Impact fee
D. Development moratorium
Correct Answer: B
Rationale: The best answer is an adequate public facilities ordinance (APFO). APFOs explicitly link
development approvals to the capacity of existing or programmed infrastructure, requiring
developers to wait until facilities are available or to pay for necessary improvements. Unlike impact
fees—which require payment but don't necessarily delay approval—APFOs can directly control the
timing and phasing of growth.
Q9: Under NEPA, a federal agency proposes to fund a major highway expansion through a wetland
area. Which document would be required if the project is determined to have significant
environmental impacts?
A. Environmental Assessment (EA)
B. Finding of No Significant Impact (FONSI)
C. Environmental Impact Statement (EIS) [CORRECT]
D. Categorical Exclusion (CE)
Correct Answer: C
Rationale: The best answer is an Environmental Impact Statement (EIS). NEPA requires federal
agencies to prepare an EIS for major federal actions significantly affecting the quality of the human
environment. The EIS must analyze the environmental impacts of the proposed action, unavoidable
adverse effects, alternatives to the action, and the relationship between short-term uses and
long-term productivity.
Q10: A metropolitan planning organization (MPO) is updating its long-range transportation plan.
Under the Clean Air Act, what must the MPO demonstrate regarding the transportation plan's
impact on air quality?
A. That all projects use electric vehicles
B. Transportation conformity [CORRECT]
C. That VMT per capita decreases by 50%
D. Compliance with NAAQS for water quality
Correct Answer: B
