CME Urban Infrastructure Design & Development 2

Question 1

Which stormwater management technique uses vegetated channels to slow runoff and promote infiltration?

Accepted Answer

Bioswale

Answer

Bioswales are vegetated, shallow channels designed to slow stormwater runoff and increase infiltration while filtering pollutants.

Question 2

In urban street design, what does the term 'complete streets' primarily refer to?

Accepted Answer

Streets designed to serve all users including pedestrians, cyclists, and transit riders

Answer

Complete streets are roadways designed and operated to enable safe access for all users regardless of age, ability, or mode of transportation.

Question 3

What is the primary purpose of a traffic impact analysis (TIA) in urban development?

Accepted Answer

To evaluate the effect of proposed development on surrounding transportation networks

Answer

A TIA assesses how a proposed development will affect traffic operations on nearby roads and intersections.

Question 4

Which pipe material is most commonly specified for new gravity sanitary sewer mains in urban areas due to its corrosion resistance?

Accepted Answer

PVC

Answer

PVC is widely used for gravity sanitary sewers because it resists corrosion from hydrogen sulfide and sewage acids.

Question 5

In the context of urban water distribution, what is a pressure-reducing valve (PRV) used for?

Accepted Answer

Lowering downstream pressure to protect pipes and fixtures

Answer

PRVs automatically reduce upstream water pressure to a set downstream pressure, protecting infrastructure in low-lying or high-pressure zones.
