you arent going to find any magician to get a huge spade in there ..

foundation plantings ..are planted to hide the foundation.. NOT ON THE FOUNDATION ...

with that in mind.. a nice bed for plants out in front of the house should be 6 to 8 feet wide ... so you have a nice 4 to 6 foot bed.. after leaving the two feet closest to the house empty .. so you can paint.. wash windows.. clean gutters.. etc ...

soooo .... if it were me ... i would cut it flush to the ground.. and apply stump killer.. and be done with it.. since i would NOT be planting anything where the stump is ...

then your only problem would be figuring out how to get rid of the brush ...

ps: another reason to move the garden bed out.. is to keep the siding dry ...

I was thinking the roots probably screwed up the drain pipes because the gutter there isn't draining. So I was thinking the roots might make it hard to get to the pipe to fix it. So i was thinking of having someone come and pluck it like this:

If you bring in that piece of equipment, you won't have any drain pipes or inground plumbing left to be worried about!! Way too big for the location and the purpose. If you want it gone, cut it down.

I think you should better explain the statement about the drain pipe which is not seen and the gutter you claim does not drain.

I can see water overflowing where the downspout connects to pipe that goes underground.

no clue about your locality ... but moving rainwater into the sewer lines is very old school.. and might not be code any longer ...

most likely you should kill that system .. and allow the water to be moved out into your lawn ...which look like it wouldnt mind some natural rain water ...

dont confuse sewer issues with rainwater removal ... it might be two different systems.. or it might be one hooked up to the other ...

ken

you might also have a used up french drain for the rainwater.. which might have nothing to do with the sewer ... and somehow it has filled up with refuse ...

i have no clue how you are going to figure it out .... ken

some version of these

Oh it's probably going out into the street, I didn't think it would be going into the sewer. I was just thinking that repairing that pipe might be difficult with the root system being in the way

just to be clear ... i am suggesting you abandon that setup.. and just deal with the water otherwise ...

ken

oh i see

let me try one more time ... avoiding the drain issue ...

you said its not draining.. and bubbling up next to your foundation.. and perhaps basement

imo... you need to fix that before the next storm ...and get the water to move out into the lawn ... so it runs away ....

and then you can worry about the long term drain project or repair ... in the future ...

Will do. I was putting this thing off but I guess I'll do it sooner rather than later now.

It is a common problem for underground storm drains (usually poorly engineered to begin with) to clog. I agree with Ken to abandon the underground portion and get the rainwater draining away from the house and yard on top of the ground. Also agree with him to cut the tree flush with grade. Paint the cut surface with undiluted herbicide to keep it from resprouting. Let it rot and forget about it. You will plant other things in different locations and the cut trunk will be covered up. It would be good to allow more space for plantings so they aren't so close to the house. Consider redoing the walk and pulling it farther away from house.
