Key facts: South Hills
About South Hills
A neighborhood known by its planets and its creek
South Hills is one of the earlier planned developments in Cedar Hill. The city dates it to 1972, counts about 447 homes and notes that locals sometimes call it the planets because of its street names.[1] It sits on the south side, off South Clark Road, with Red Oak Creek running alongside, and Liberty Park and Dot Thomas Park nearby.[1]
Two facts in that description shape nearly every water problem here. The homes are over fifty years old, and there is a creek close by. A resident who finds water on the floor needs to separate those two possibilities before doing much else, because the cleanup, the urgency and the insurance conversation all depend on which one it is.
Sort it first
Creek water or pipe water in South Hills?

Flood risk
What Red Oak Creek does and does not tell you
Being close to a creek is a reason to look, not a verdict. Elevation, lot grading and where a house sits relative to the channel all matter, and two homes on one street may be mapped differently. FEMA flood maps show how a given address is mapped.[2] Check yours on a dry day, and remember that a map shows modeled risk and not a promise. Water can reach homes outside a mapped zone.
The heavy rain of August 2022 is a useful local reminder. Reporting at the time described homes in Cedar Hill damaged by a creek flood, although the report did not name the exact street, so nobody should read it as saying South Hills flooded.[4] The lesson is simply that short, intense storms here can raise small creeks quickly.
Around the house
Keeping South Hills storm water moving away from the slab
Most rain problems begin close to the wall. After fifty years a yard has often settled, and flower beds and added patios can tip water back toward the foundation. Downspouts that end at the corner of the house do the same.
Walk the lot in a real rain, with a coat on. Watch where the water goes. Ten minutes of that tells you more than any general advice, and the fixes are usually modest: extensions on downspouts, cleaned gutters, and soil sloped away from the wall.
- Extend downspouts away from the wall
- Keep the weep holes in brick clear
- Report blocked street drains to the city

City or owner
Who looks after the creek and the culverts
The city Streets and Drainage division maintains creeks and drainage channels and clears debris from culverts and storm sewers.[5] If a street inlet near your home is blocked, or a culvert is plugged with debris after a storm, that is worth reporting rather than attempting yourself. Never go near moving water to clear it.
Water on your own lot and in your own home is your side of the line. Keep notes and dated photos if a blocked drain seems to have played a part.
During the event
When storm water gets into a South Hills home
- 1
Put safety first
Do not walk through water near outlets or appliances, and leave if water is rising.
- 2
Treat it as contaminated
Flood water can carry sewage and chemicals, so keep skin and children away from it.
- 3
Record the water line
Photograph the height on walls before cleaning, with something that shows scale.
- 4
Protect what is dry
Move belongings upward and away, without carrying wet soil into clean rooms.
- 5
Call once it is safe
Say it came from outside and mention how high it reached.
Materials
Why outside water changes what can be kept
A clean burst pipe may leave carpet that can be saved. Storm water that has crossed a yard usually does not. Pad, soaked drywall and insulation in the lower wall are commonly removed, because they hold whatever the water carried. Solid materials such as tile and concrete can be cleaned and dried.
Do not rush to put things back. The EPA advises drying within 24 to 48 hours to help prevent mold, and wall cavities can stay wet after a room looks finished.[6] Ask for readings from inside the wall, not just the surface.
Indoor leaks
Fifty-year-old plumbing on a 1972 street
If the original pipes are still in place, they have had a long working life. A home of this age may also have been partly repiped, so one bathroom can be new and the wall behind it original. Nobody can tell from the curb. Look at what shows at the water heater, under sinks and in any access panel, and ask a plumber what is behind it.
Old drains deserve the same interest. Roots, settled joints and years of grease can slow a line until it backs up during a heavy rain or a busy morning. If a drain slows every time it storms, mention that pattern, because it can mean ground water is reaching the sewer line.
Lead-safe work
Cutting walls in a pre-1978 South Hills home
A 1972 home falls before the federal cutoff, so paid renovators who disturb painted surfaces generally have to follow lead-safe practices under EPA rules.[3] That covers more than people expect: cutting a wet wall, removing trim and pulling out window stools can all count. Ask how dust will be contained, particularly as drying equipment moves a lot of air.
Look for
South Hills signs after a wet week
Damp along the door threshold
Often driven rain or poor grading rather than a pipe.
Silt in the garage corner
Water has been through even if it has gone.
A sour smell near a floor drain
The sewer may be struggling after the storm.
Paint bubbling low on an outer wall
Moisture may be sitting in the wall itself.

Prepare
Getting ready before the next South Hills storm
A little planning goes a long way when a storm is on the forecast. Keep papers and photographs on a high shelf, not in the bottom drawers. Know how to shut off power and water. Move the car if your driveway collects water. Take dated photos of each room now, since a clear record of how things looked makes any later claim easier.
Keep your distance from Red Oak Creek and the trail corridor when it runs high. The water moves faster than it looks, and banks can give way.
The low point
Reading a garage after a South Hills downpour
In many homes the garage floor sits a step below the living space, and that makes it the first place outside water shows up. A thin sheet of silt along one wall, a damp line on stored boxes or a rust mark on a shelf leg tells you water has been through, even if nobody saw it. Look at those marks after a big storm. They show the direction the water came from, and that points you to the fix.
Cardboard is a poor friend here. Boxes on a garage floor wick water upward and quietly grow mold on the side facing the wall. Plastic bins on low shelves take up little room and keep the record of what the water did easy to read.
If the wall between the garage and the house has damp at its base, tell the contractor. That wall often hides the line to the water heater, so it can be wet from either direction, and it deserves a reading rather than a guess.
Once the garage has dried, sweep up the silt rather than hosing it toward the house, wear gloves and a mask while you do it, and throw out anything soft that sat in the water.
Changed drainage
Fifty years of fences, patios and added concrete
The lots here were graded once, half a century ago. Since then owners have poured patios, built sheds, raised flower beds and put up solid fences, and each of those can change where a heavy rain goes. A wooden fence with no gap at the bottom can hold water against a wall like a low dam. A neighbor's new slab can send runoff your way without anyone meaning to.
If water started reaching your home only after a change nearby, write down when you first saw it, and take photos during a rain. Talk to the neighbor before it becomes a dispute. Many of these problems are small and can be solved with a shallow swale, a gap at the base of the fence, or a drain line that both sides agree on.
Trees matter as well. Roots and leaf litter can block a small yard drain long before anyone notices. Pour a bucket of water into each yard inlet on a dry day and watch that it runs out where it should.
Be specific
What to tell a South Hills contractor on the first call
A clear description shortens the visit. Say where you first saw water, how deep it was, and whether it was clear or brown. Say whether it is still coming in. Mention if the house has had water before, and where, since old damage can look like new damage once it gets wet again.
Tell them about access too. If the only way to the rear of the house is a narrow gate, or the street near the creek is closed, the person on the phone needs to know. Ask what they will do first, and what you should leave untouched until they get there. Agree on any next steps while you are on that call.
FAQ
South Hills water damage questions
Is my South Hills home in a flood zone?
Look up your address on the FEMA flood maps. Being near Red Oak Creek does not settle it either way.[2]
Did South Hills flood in August 2022?
We could not confirm that. A news report described a creek flood damaging homes in Cedar Hill, without naming the street.[4]
Why does my drain slow when it rains?
Ground water can get into an old sewer line through its joints. Tell a plumber about the pattern, as it helps them narrow it down.
Can I save carpet after storm water?
Usually not. Outside water can carry contamination, so pad and carpet are often removed. Ask the contractor to assess it.
Who clears the culvert near my house?
The city Streets and Drainage division handles creeks, channels and culverts, so report problems to them.[5]
