Do you think city will mind if i put the drainage channel going out to the ditch by the road?
I have to call the 1 call dig people, i should mention the channel i think..
I should use solid no holes pipe for that part going to the ditch?
You are going to have to account for the gravel around the pipe as well. How wide of a trench? If you figure a 1' wide x 100' long x 4" deep of solid matter would be 2.4 tons. It will likely take a bit less.
You will have to talk to the city to see if they will let you connect to the ditch
Dig-a-lert 800-422-4133 is the number I call, pretty sure they are nationwide. It's a free service and required before you dig or if you hit something it will automatically be your fault. They are not going to care what you are connecting to, they are only going to ask you what you are putting in which is storm drain and they are going to ask you how you plan on excavating the area.
You will want to use solid pipe anywhere you are not going to have gravel around it.
