CMM Environmental Sustainability 5 — Questions and Answers
Question 1: A city is developing a Vulnerability Assessment for climate adaptation planning. Which community asset would be considered MOST vulnerable to sea-level rise?
- Inland municipal administrative offices
- Coastal wastewater treatment infrastructure built at sea level (Correct answer)
- Elevated highway interchanges
- Mountain watershed protection areas
Correct answer: Coastal wastewater treatment infrastructure built at sea level
Low-lying coastal infrastructure like wastewater plants faces the most direct risk from sea-level rise, including inundation, storm surge damage, and saltwater intrusion.
Question 2: Under the National Environmental Policy Act (NEPA), when is an Environmental Impact Statement (EIS) required?
- For all projects costing more than $1 million in federal funds
- When a federal action may significantly affect the quality of the human environment (Correct answer)
- For all state highway construction projects
- Whenever a municipality seeks a federal grant for any infrastructure project
Correct answer: When a federal action may significantly affect the quality of the human environment
NEPA requires an EIS for major federal actions that may significantly affect the quality of the human environment, based on significance determined through an Environmental Assessment.
Question 3: Which approach BEST describes Integrated Pest Management (IPM) as used in municipal parks and public lands?
- Applying maximum pesticide doses to ensure complete pest elimination
- Using the least toxic effective methods, prioritizing prevention and biological controls over chemicals (Correct answer)
- Eliminating all pest species from public lands regardless of ecological role
- Contracting all pest control to private vendors without municipal oversight
Correct answer: Using the least toxic effective methods, prioritizing prevention and biological controls over chemicals
IPM uses a combination of prevention, monitoring, and targeted interventions with preference for non-chemical methods to manage pests with minimal environmental impact.
Question 4: A municipality adopts a Complete Streets policy. How does this relate to environmental sustainability?
- It requires all streets to be paved with environmentally certified asphalt
- It designs streets for all users including pedestrians and cyclists, reducing auto dependency and emissions (Correct answer)
- It mandates street trees be planted at specific intervals for carbon sequestration
- It prohibits commercial vehicles from residential streets to reduce pollution
Correct answer: It designs streets for all users including pedestrians and cyclists, reducing auto dependency and emissions
Complete Streets make walking, cycling, and transit more viable, reducing vehicle miles traveled and associated greenhouse gas emissions and air pollution.
Question 5: A city is evaluating its drinking water system's sustainability. Which indicator would BEST measure water use efficiency?
- Total annual water revenue collected
- Non-Revenue Water (NRW) percentage representing system losses (Correct answer)
- Number of water main breaks per year
- Annual capital investment in water infrastructure
Correct answer: Non-Revenue Water (NRW) percentage representing system losses
Non-Revenue Water measures the percentage of treated water lost through leaks, theft, or metering inaccuracies before reaching paying customers, indicating system efficiency.
Question 6: A city manager is responding to a constituent complaint about an industrial facility emitting odors and noise in a low-income neighborhood. This is MOST directly an issue of:
- Zoning variance compliance
- Environmental justice and cumulative environmental burdens (Correct answer)
- Federal air quality attainment status
- Industrial permitting fees
Correct answer: Environmental justice and cumulative environmental burdens
Cumulative environmental burdens on low-income and minority communities is the defining concern of environmental justice, requiring equitable consideration in siting and permitting decisions.
Question 7: Which of the following is the BEST example of a co-benefit from municipal tree planting programs?
- Increased administrative costs for tree inventory maintenance
- Simultaneous reduction in urban heat, stormwater runoff, air pollution, and improved mental health (Correct answer)
- Requirement for additional street sweeping due to leaf litter
- Need for expanded utility line management
Correct answer: Simultaneous reduction in urban heat, stormwater runoff, air pollution, and improved mental health
Urban trees deliver multiple simultaneous benefits—cooling, stormwater retention, air quality improvement, and psychological well-being—making them highly cost-effective sustainability investments.
