Water is running down a hill from my neighbors downspouts.
The water goes under my porch...

How far is your neighbors downspout from the property line?
How far from there to your porch?
How old are your homes?

...in the ground to block that water and redirect it...?

There should already be something there to prevent this..
but they will deteriorate over time.

 

Water runoff going under my porch

Thank you for your reply. My neighbor's downspout is about 7 feet from the property line, 25 feet from my porch. My hone was built in 1998.

 

we need pics.

 

Might be easier to ask if your neighbor would be willing to relocate the downspout so it doesn't send water in YOUR direction.

 

Water Runoff

My neighbor would have to pay hundreds if not thousands of dollars because he has two downspouts that drain on his concrete driveway.

Might cost you the hundreds, if not thousands of dollars then instead.

 

don't assume . post some pics.

 

Depending on where you live...some cities have building codes that prevent a neighbor from sending intentional run off into your yard. Intentional being run off that he has control over. He can't control the rain that falls on his yard. But if he collects it in rain gutters...he can't send it into your yard.

So I would put in a call to the city.

One question....have you talked to your neighbor about it?

 

Install a swale on the property line. The water will collect in the low spot and disappear over time OR as long as you are digging install a drainage system......12x12 trench, then drainage gravel , then 4inch weeping tile, more gravel, soil then grass it over.
The whole thing is hidden. I did that in on my property...works like a charm...mine daylights about 100 feet away

 

Install a swale on the property line.

i am planning just such design. but using a patio to do it.

 

I'm not sure I understand how you can build a patio on that spot...OP..sorry to temporarily divert your thread..

Also, if digging a swale proves impossible because of trees and their pesky roots, alternatively you can build a berm so he can keep his own runoff. Turn it into a flower or shrub bed so you can say you are just adding beautiful landscaping

 

I'm not sure I understand how you can build a patio on that spot

go see my patio thread for what i am planning.

 

For instance: When I installed a motion detector above my garage door I didn't realize that the strong light was disturbing my neighbours evening smoke.

He kindly asked for a small adjustment. He's happy now and shifting the lamp over an inch or two doesn't effect me in the least

 

Not sure if your neighbor re-locating the downspout is going to help anyways if you are at the bottom of a hill. Water flows down-hill. The swale could be a good idea, but you have to have a plan for where the water will go. Again, remember it WILL flow down hill.
The grade of the land may (or might not) be obvious in a picture, but probably you should spend a couple of hours out there with some sticks and a line level and map out accurately what the slope of the yards are. (i.e place a couple of 1x 2's about a foot high, about 10 feet apart, place a level string across the two until it shows level, ... if the height of the string is two inches higher on one end, then grade slopes down two inches. repeat and map onto a piece of paper until you understand the slope of the whole yard)

 

Here are pictures of the water runoff area.There are two downspouts in front of the cars that run onto the driveway, cown the grassy hill and under my poch where the lattice is. My downspout to my house is to the right of the lattice. That downspout is connected to a drainpipe that carries the water to my driveway. What can I do to block the water and reroute it to the right toward the downspout?

Water Runoff from Neighbor's House

Here are two pictures. One picture shows the downspouts in front of the car. THe water flows down on the concrete and the driveway has a decline toward my porch. The other picture shows the lattice below my porch where the water flows. My downspout is on the right corner of that lattice. How can I block and reroute the water so that it will run toward my downspout?

I hope you can see the pictures; I had a difficult time reducing the size.

 

Those pics are worthless.....

Don't reduce....use something like Photobucket to host the pic

 

I have better results with jpeg attachments
The chatroom routines will allow 100K attachments (sometimes a little more).

 

When trying to share an image on Flickr, you have to do it a bit differently.

1. Make sure you have your preference for images on Flickr set to public.
2. Look for the share tab. It looks like a partial square with a angled arrow.
3. Once you have clicked the share tab, click on the one that looks like a push pin.
4. Copy and paste the provided coding for forums.

Screenshot of the process here.

Using that code will give you these results.
