We have a strange drainage configuration that is quite broken.
One of the downspouts comes off the house and goes directly into a 4 inch PVC pipe in the ground. The PVC pipe goes about 2 feet down at about a 75 degree angle and then ends.
Obviously, when it rains, the 2 foot pipe backs up, and the water comes pouring out the top, back towards our foundation.
So, some questions:
1) What was this supposed to be doing?
2) What should we do to fix it? Our community requires that all storm drainage not end up in the street (they do dye tests to check for this), so we have to somehow keep the water on our property.
This entire thing is about 15-20 feet from the street. There's a small flowerbed where the drain comes out, then some lawn, and a large sycamore tree. (See bad MSPaint picture.)
Depending on the age of your home, your downspout may be tied directly into the city's Storm sewer system. The pipe may appear to end however it may just be clooged with debris. In any event, discharging to sewer is probably no longer allowed. If you have to keep it on your property consider using that future planning bed as a rain garden and direct the stormwater there. You basiclly use highly permeable soils (sands/gravels) and plants which can sustain large volumes of water. Check out this website for more info. on rain gardens.
