Total questions: 7
Worksheet time: 4mins
Bioretention is an example of what kind of LID?
Structural LID
Non-structural LID
Integrated LID
Integrated non-structural LID
Examples of LID Practices can be understood as Prevent - Detain - Infiltrate - Evapotranspire - Capture - Re-use
Which of the following does not fit into any of those categories?
Swales. Terracing, and check dams
Rain barrels and cisterns
Water Turbines
Green Roofs
Well designed LID Practices with pre-treatment are easier to maintain than conventional SWM practices
True
False
Which of the following is a direct benefit of LID?
Delayed timing of peak runoff
Improved stream erosion
Reduced runoff temperature
All of the above
The ratio of impervious drainage to pervious/facility footprint area (I:P area ratio) for an area being treated by a bioretention cell should be kept at what ratio? (footprint of the impervious drainage area)
1:1 to 1:2
100:1 to 50:1
5:1 to 20:1
1:2 to 3:4
Which options are NOT roles of plants in biorientation systems?
Pollutant removal, Asethetics
Water uptake, Flow barriers
Soil stabilization, Aid for Infiltration
Nutritious and accessible roadside vegetables
Having a diverse selection of plants in a bioretention system:
Increases the success of the system
Is prohibitively costly
Can be devastating as plants are tribal
Scares away wildlife and small woodland creatures
