ENV SP Water Conservation and Management 2

Question 1

Under Envision credit RA1.2 – Protect Freshwater Resources, which practice is most effective at reducing non-point source pollution entering waterways?

Accepted Answer

Using vegetated buffers and bioretention areas

Answer

Vegetated buffers and bioretention areas filter pollutants from runoff before it reaches streams and water bodies, directly protecting freshwater quality.

Question 2

What does 'stormwater runoff reduction' primarily achieve in urban infrastructure projects under the Envision framework?

Accepted Answer

Reduced peak flows and decreased pollutant loads to receiving waters

Answer

Reducing stormwater runoff lowers peak flow rates and pollutant loads to receiving water bodies, protecting aquatic ecosystems and downstream infrastructure.

Question 3

Which of the following is an example of green infrastructure used to manage stormwater on infrastructure projects?

Accepted Answer

Green roofs and permeable pavements

Answer

Green roofs and permeable pavements are green infrastructure approaches that retain and filter stormwater close to where it falls.

Question 4

The concept of 'water balance' in a sustainability assessment requires the project team to account for which of the following?

Accepted Answer

All water inputs, outputs, and on-site storage over the project lifecycle

Answer

A water balance accounts for all inputs (precipitation, municipal supply), outputs (evapotranspiration, discharge, consumption), and storage changes over time.

Question 5

In the Envision framework, why is protecting groundwater recharge areas important during infrastructure planning?

Accepted Answer

Disrupting recharge areas can reduce long-term availability of groundwater supplies

Answer

Groundwater recharge areas replenish aquifers; disrupting them with impervious surfaces reduces long-term freshwater availability for communities and ecosystems.
