D. To provide underground sewage Correct: B Explanation: Vegetated swales are shallow, planted channels that slow, convey, and treat stormwater using plants and soil. Question 12 Which practice helps reduce the urban heat island effect? A. Asphalt paving B. Green roofs and increased tree canopy C. Removing vegetation D. Increasing building density only Correct: B Explanation: Green roofs and tree canopies provide shade and evapotranspiration, helping to cool urban areas. Question 13 What is a constructed wetland primarily used for in GI? A. Building foundations B. Stormwater treatment and habitat creation
(NGICP) Examination Exam
C. High-speed rail construction D. Commercial farming Correct: B Explanation: Constructed wetlands filter stormwater, remove pollutants, and provide valuable wildlife habitat. Question 14 Why is soil selection important in GI projects? A. It determines filtration and infiltration capacity B. It has no impact on project success C. It is only for aesthetic purposes D. It increases project cost Correct: A Explanation: The soil’s properties directly affect the ability of GI to filter pollutants and allow water infiltration. Question 15 Which of the following is a social benefit of Green Infrastructure? A. Reduces property values
(NGICP) Examination Exam
A. Heavy metals B. Lightweight soil and drought-tolerant plants C. Asphalt shingles D. Synthetic turf only Correct: B Explanation: Green roofs require lightweight soil mixes and drought-tolerant plants to ensure proper growth and structural support. Question 18 Which is NOT a purpose of infiltration trenches? A. Increase stormwater infiltration B. Provide pollutant removal C. Increase runoff D. Reduce flooding Correct: C Explanation: Infiltration trenches are designed to promote water infiltration and reduce surface runoff, not increase it.

D. Filling with gravel Correct: B Explanation: Regular debris and sediment removal helps vegetated swales maintain their stormwater conveyance and treatment function. Question 23 What is the main goal of integrating GI into existing urban environments? A. To increase impervious surfaces B. To restore ecological function and manage stormwater C. To remove green spaces D. To promote industrial development exclusively Correct: B Explanation: Integrating GI restores ecological processes and manages stormwater sustainably within developed areas. Question 24 Which of the following increases the effectiveness of green walls? A. Using native, drought-tolerant plant species B. Using only artificial plants
(NGICP) Examination Exam
C. Painting the wall green D. Avoiding irrigation Correct: A Explanation: Native, drought-tolerant plants are adapted to local conditions and require less water, improving green wall performance. Question 25 What is the purpose of sand filters in GI? A. Filtering pollutants from stormwater B. Generating electricity C. Cooling buildings D. Producing sand for construction Correct: A Explanation: Sand filters treat stormwater by removing sediment and pollutants as water filters through sand media. Question 26 What is the role of real-time monitoring technology in GI? A. To track system performance and optimize maintenance
(NGICP) Examination Exam
A. By increasing runoff B. By capturing, slowing, and infiltrating stormwater C. By paving over wetlands D. By diverting all water to a single point Correct: B Explanation: GI captures and manages stormwater, reducing the volume and speed of runoff that can cause flooding. Question 29 Which is a key consideration in designing GI for long-term performance? A. Selecting suitable plant species and materials B. Ignoring local climate C. Using only non-native plants D. Avoiding community input Correct: A Explanation: Proper selection of plant species and materials ensures GI systems remain functional and resilient over time.
