Dip In Road
Dip In Road
(OP)
hi,
does anybody know what a dip in road is? when is it best to use and what should be the specs.
i am designing an access way for the utility area of the project i'm working on and this particular access way will block all possible drainage going to the ditch around that area. our client wants to use a dip in road to solve the drainage problem of that area.

Then again, a "dip" in the road is a depression, or a really stupid person standing there...

actually, Ductile Iron Pipe was the first thing that came in to my mind. But according to our client, it's not.
I agree that it's a road depression. I just wanted to know
what are the specifications for this type of design. A drawing detail would be the best answer.
thanks

Even if this road is a temporary structure for during utility construction it needs to withstand at least a 2 year design storm, possibly a 10 year design storm. If the road will not be surfaced, then a "dip" or traversable ditch (ford) would need to be armored with riprap, concrete or asphalt, all of which would likely cost more than a culvert.

Tnx for the advice.

Try searching for standard drawings in the DOT websites for Arizona, New Mexico and possibly California and West Texas.
good luck

If there is a ditch along the main road then you'll likely have problems matching the depth of the dip to the bottom of the ditch. I have property owners ask to do this all the time on their driveways when they're too cheap to put in a culvert.
The only time I relent is when the driveway, or in your case the utility road, is at the crest of a hill along the road. In this case the water from the driveway ditches will flow off in opposite directions downhill and the dip will divert water that might come down the driveway so it doesn't flow out into the main road.
If the utility road does not come off a crest like this and there is a ditch to cross then you need to design a culvert.
