Explain what type of development—1 house per acre with 20% impervious cover or 8 houses per acre with 65% impervious cover—generates more stormwater and why.
What will be an ideal response?
The development that has 8 houses per acre generates more stormwater, because it has a much larger proportion of impervious cover (65% vs. 20%). Impervious cover prevents stormwater from naturally infiltrating the ground, and creates runoff.
