Forecast note (as of Nov 5, 2026): NOAA's Climate Prediction Center has an El Niño Advisory in effect and expects a strong-to-very strong El Niño through January–March 2027, with chances remaining above 83% (CPC ENSO discussion, Oct 8, 2026; CPC status update, Nov 2, 2026). The National Weather Service in Los Angeles (AFD 12:43 PM PST Nov 5) keeps dry offshore weather through about Wednesday, a chance of light rain Thursday, Nov 12, then wet and unsettled weather from about Friday, Nov 13 into that weekend, with ensembles showing decent chances of widespread 1+ inch totals though timing and amounts remain uncertain (NWS Los Angeles AFD). NWS San Diego likewise flags a large trough late next week with substantial rain possible but low confidence in the details (NWS San Diego AFD). El Niño raises the odds of a wet winter, but it doesn't guarantee one. Check weather.gov/lox before each storm.
Studio City is home base for us. Our main office is right here. The homes up in the hills on the south side of the neighborhood are built into the slope, and almost every one of them depends on retaining walls to hold the yard in place.
A retaining wall isn't only holding back soil. It's holding back water. Behind most walls is gravel and a drain pipe, with weep holes along the face to let water out.
We're local, so we can usually get to you the same day. See our Studio City drain cleaning page.
Warning signs that mean "leave and call 911": cracks opening in the ground or walls, tilting trees or fences, sudden mud or debris flow, or doors that suddenly stick. A pump doesn't fix a moving slope. Follow evacuation orders from your city or county.
On a hill, gravity does part of the work. Put the pump at the low spot where water collects, usually the garage threshold, a lower patio or a window well. Then run the hose downhill to the street. If the curb sits above the low spot, buy a pump rated for that lift. Full guide: pump, hose and outlet.
Water and electricity can mix safely only when you set them up correctly. Here's how I set up every pump:

It can mean they're clogged, so water builds up behind the wall. Have them and the drain behind the wall checked.
