I've had to rim the entire house with foundation drains and surface drains as my last stand against my hillside above us. All of my raingutters terminate into concrete dranbboxes that dump into 4" drain pipe that quickly evac's it from the house.
Then what to do with it?
I dug a likely 100' trench out to what we call the sump, which is an odd low point out at the street edge of the property. From there, the drain pipe resurfaces, flows into a low area about 20' diameter, and it soaks into a stand of Live Oaks, and my lower lime grove. Its like a small pond, this sump, but, it is so sharply draining, that when we emptied our swimming pool, which quickly dumped 12k gallons of water, it never even puddled, it just went straight into the ground. The sump is an odd anomaly.
Fortunately, I don't have to deal with hillside runoff except in extreme 100 year rain events and even then, it is not that much. Did the rim for my house as well. There is no open ground around my house. Drains all the way to the street.
