Question 6. [3 Points] For a new project located in Trenton, NJ, it has been determined that the path fr the hydraulically most remote point of the drainage area to the point of concentration takes the followi path: 1. 800 ft of paved surface at a 1.5% slope 2. 140 ft of poor grass surface at a 0.9% slope 3. 60 ft of dense grass at a 6.0% slope 4. 1,600 ft of stream flow at a 1% slope.
