A construction site's storm water plan (SWPPP) requires controlling sediment at the point where runoff leaves the site through a street drain. Which best management practice DIRECTLY protects that storm drain inlet?

Correct: storm drain inlet protection, such as gravel bag barriers, fiber rolls, or filter inserts placed around the inlet, directly traps sediment before runoff enters the drain. Watering the haul road controls dust, not inlet sediment. Adding parking does nothing for the drain. Sweeping office floors is unrelated to protecting the storm drain from site runoff.
