Ground drainage questions

Hi,

I have a two landscaped beds next to my home that tend to collect water - when it rains - at the downhill corner of each one.

I buried ADS black plastic corrugated pipe into the lawn to pickup 2 gutter downspouts. *
Those pipes run downhill and are exposed to air and the downhill end. That works fine.

I'd like to drain the water from the 2 beds and thus I am wondering the best way to do that....

The downhill corner of the one bed is about 10 feet away from one of the buried pipes. I'm considering cutting a Y into the main run (down hill of the corner of the bed or course) and running a pipe to the bed corner. *At the corner itself I have an NDS drain. *I worry about debris getting into the drain and eventually clogging up the works. *Is is reasonable to but a piece of landscape fabric under the grate (which is removable) to prevent this?

The downhill corner of the other bed happens to be just about right over one of the buried ADS pipes. *Should I fashion a system like the one I describe above? * Or would it be better to remove the soil around the pipe (at the corner of the bed), drill holes in the pipe, cover the pipe with landscape cloth, then fill the hole with stones?

I like the second alternative if there is a way to then cover the stones with landscape fabric and dress the whole thing with mulch.
If the second route can work, where to I drill the holes? *top, sides, or bottom?

Thanks for any help!

Is it possible to raise the soil level in the beds to get plants above drainage problems? I assume you live where there is heavy clay? Raising level of beds with additional soil may require you to lift some plants, but it may be an easier option. Raised beds are a popular option where there are drainage problems.

Drain holes in pipe are usually placed on top to collect settling water as it moves through soil. Placing landscape cloth over holes would certainly prevent clogging of holes and pipe.

The issue is not that the beds themselves get too wet. In fact, they are raised up.
The problem is that water drainage from the beds collects at a low spot at the lower corner of the bed - which is away from the house. I merely want figure out the best way to remove the water that does collect there... I use a flat spade to dig a trench to edge the bed - to prevent grass from growing in the bed - and that trench tends to collect water...

Perforated drainage pipe could be used to drain water away from trench. Dig trench deeper and place pipe with holes facing up. Cover with landscape cloth to prevent clogging. Then, cover with gravel. Pipe can drain to a storm sewer or gravel pit (dry well).
