Hello again, Any comments, suggestions would be greatly appreciated. My question, I intend to use a small soil compactor in the 30 inch wide ditch to compact the loose soil after regrading is complete. I have not found any type of test device to determine the percentage of soil compaction for...

Thanks Ryb01, you have been a great help! Nice pics too, sorry to be so slow! FD

Interesting ideas Ryb01, The goal is a no mow yard, although there is concern the swale will erode without some plants and rocks to hold the soil. The home owner is looking for a natural look, could fescue or other types of low maintenance grasses with a decent root base be used in a no mow...

Great ideas thanks Ryb01, adding a berm and making the swale as wide as the yard will allow seems to be the solution. The rain gutter down spouts across the back of the house drain into an existing pipe that has inlets picking up surface water hopefully it will take care of any 'other water'...

Thanks Ryb01, Creative grading, interesting idea, any suggestions, pics or such to share?

Hello ryb01, You are correct the house was built in 1976. 1. Current drainage regulations in this area, I haven't investigated, for this lot any storm water what ever the source is the owners problem. Permits, there is one on record for the house. It doesn't show where utilities connect to the...

WOW, Thanks beej67 !!

Hello again, I had the good fortune to speak with a civil engineer with the city planning/building department, my ditch size questions have been answered. Attached are pictures of the should I say, lack of progress? The area next to the house was excavated to make room for the dirt from the...

Hello, I forgot to add a disclaimer, I agree I will not at any time or in any way attempt to hold any one liable for the suggestions they have given on the repair or corrections of this drainage ditch. The disclaimer was probably not necessary, but I really need to get this drainage situation...

Hello again, First and foremost I want to thank all of you pros for sharing your expertise on this failed drainage ditch! With that said, only through your guidance we have established the total area of the 4 lots draining onto the this lot is about 1 acre, and the acre is flat. The soil is...

Thanks for asking beej67 this may be of benefit to others on his thread. The area is Sacramento county CA, with 23 inches average annual rain fall. This being July chances are slim there will be a 'real rain' before Nov.. The rainy season is from Dec to May or June, the heaviest being in Dec - Feb.

Thanks CVG! Great idea! Actually winter rain is the driving force behind getting a solution to this drainage issue.

Thanks for responding beej67, I have attached the aerial view source of the water/beginning of the ditch =3 red spots path of the ditch= blue line Sadly the ditch exists, the goal is to correct the situation before winter rains begin. The house is on a city street, storm water from...

Thanks for responding cvg, Definitely, first the slope of the ditch must be reestablished. Only then would bentonite be something to consider. As per July 12; 5. It doesn't matter what the upstream capacity is, you have a bottlenect at the bottom. * Yes, the bottle neck is accessible to...

Thanks beej69, The ditch is for control of 1 acre of storm water. You are correct the ditch was dug in silty clay fill at the corner of the house. Lowering the ditch invert below the finished floor elevation of the floor of the house is not possible. This is in the area of the 2' rise from...

Oldestguy, I apologize for posting my question in this thread. I joined this forum to ask you where I might get directions on sealing a ditch with bentonine. While looking for a method to seal a seeping ditch (O, yes it has other problems that must be corrected first!) I found some of your...

Thanks for responding cvg, To help clarify; 1. Regarding the fill, was the fill gravel, sand or clay? *The fill is soil from excavation of the ditch, it is clay. 2. You should always place a filter beneath riprap in a ditch. *Absolutely! But there is no filter...yet 3. I am still unclear -...

Thanks much for contributing beej69. I agree, the numbers are confusing, the flooding began the first time water traveled through the ditch. The ditch is filled with 1 1/2 -3/4 drain rock. The beginning of the drain is 48 inches higher than the side walk. The area where the flooding begins is...

Thanks for responding beej67, Yes, this issue is only about surface water, average rain fall is 23' a year. True some home work on Manning's equation is required. The 4 lots draining on to this one total an acre. They all sit below 'their' street. The 4 lots are flat. The lot they drain on to...

Hello cvg, The ditch was dug a week ago, there has been no rain or water from any neighbors, it was tested using a garden hose at the uppermost end. There were 2 low spots in the backyard, they were built up to created a consistent slope, there was compaction, obviously not enough, the seepage...
