Calculate the time of concentration for a concrete parking lot that is 300 ft wide by 600 ft long. The longest flow path is 300 ft of sheet flow across the lot on a slope of 0.5 percent and 600 ft of shallow concentrated flow along the parking lot's length in a paved channel on a slope of 1.5 percent.

**Calculating Time of Concentration for a Concrete Parking Lot**

A concrete parking lot measures 300 feet in width and 600 feet in length. 

- **Flow Path Description:**
  - The longest flow path involves 300 feet of **sheet flow** across the lot with a slope of 0.5 percent.
  - Following this, there is 600 feet of **shallow concentrated flow** along the parking lot’s length in a paved channel, which has a slope of 1.5 percent.

To calculate the time of concentration, one would consider these flow paths and their associated slopes.
