This article is brought to you by TLC Incorporated — Maryland’s trusted team for stormwater solutions, yard drainage, and straight talk from Bob Carr.
Hi, I’m Bob Carr. I’ve been walking Maryland yards after storms for over three decades, and I can tell you this: your yard is talking to you.
The trick is knowing how to listen.
Every puddle, every channel, every patch of standing water is a clue.
So after the next storm, don’t just sigh and wait for it to dry out. Take five minutes to do this diagnostic walkthrough. It could save you thousands.
Let me show you exactly how I do it.
1. Start at the Top: Roof Runoff
Walk around your home. Look at the ground just below every downspout. This is where water should be managed well — and often where problems start.
Ask yourself: – Is water pooling near the foundation? – Are splash blocks shifted or buried? – Is there mulch washout or exposed dirt? – Is the downspout even connected?
What it means: Your downspouts aren’t doing their job. If water lands within 3–5 feet of your walls, it’s already trying to get inside.
Pro tip: I recommend burying downspouts and running them 10–20 feet out to a safe discharge point. Pop-up emitters, dry wells, or sloped lawn zones work great.
Common fix: Downspout extensions with buried solid pipe and a pop-up emitter cost $800–$2,000 per zone and solve more water problems than any other single improvement.
Real homeowner story: One homeowner in Annapolis called me because their finished basement carpet kept getting wet after big rains. They were convinced it was a cracked foundation. I walked the property and within 30 seconds I saw it: all four downspouts were dumping water just two feet from the house. No cracks — just mismanaged roof water. We buried the downspouts with solid pipe and pop-ups. Three years later, bone dry.
2. Follow the Flow
Now that you’ve checked where water starts, trace where it’s going.
Stand at the highest part of your yard. Look downhill.
Ask yourself: – Where is water collecting? – Can you see flow lines in the grass, mulch, or gravel? – Is water crossing walkways or pooling near the driveway?
What it means: You’re seeing the water’s natural path. If it ends up near your house, deck, or patio, that’s a red flag.
Bob’s tip: Water is lazy. It always takes the path of least resistance. Your job is to spot where that path currently leads and decide if it’s where you want it to go.
Case story: In Davidsonville, a homeowner had water running across their flagstone patio every time it rained. We spotted the flow line on the first walk, rerouted with a trench drain and catch basin, and now the patio stays bone dry.
3. Spot the Low Spots
Low spots are the usual suspects in most lawn drainage problems.
Ask yourself: – Is this area wet longer than the rest of the yard? – Are there signs of algae, mud, or dead grass? – Does it drain slowly, or not at all?
What it means: You likely have compacted soil, a grading issue, or a drainage outlet that isn’t working. Many low spots are created during construction and never addressed.
Bob’s recommendation: We often fix these with a combination of regrading, soil rebuilding, and a micro-drain or French drain system. But it starts with understanding why the low spot exists.
Cost insight: Minor grading corrections run $1,500–3,000. Add a micro-drain and you’re in the $4,000–6,000 range depending on access and materials.
4. Check the Edges
Edges of your yard, especially where beds meet lawns, often collect water without you realizing it.
Walk your fence lines, garden borders, and bed edges.
Ask yourself: – Is water trapped by edging or border walls? – Has mulch piled up and formed a dam? – Are plants sitting in soggy soil?
What it means: Your landscaping is unintentionally trapping water. That water needs a path out. We’ve reworked hundreds of bed lines to open escape routes for trapped water.
Case example: In Severna Park, a simple 20-foot border of stone edging was holding back thousands of gallons. We cut two drainage windows and rerouted water to a side swale. Cost: $1,200. Result: dry flowerbeds and no more rot on the siding.
5. Look at the Exit
Every yard needs an exit strategy. If your water has nowhere to go, it will find its own way — and that often means your basement.
Ask yourself: – Where does all this water go? – Is there a swale, storm drain, or pop-up emitter? – Are those exits clear and working?
What it means: If you can’t find the exit, neither can the water. Time to rethink the flow.
Bob’s tip: The end of your system is just as important as the beginning. A clogged pop-up emitter or blocked swale can back up water all the way to your walls.
Bonus Checks: The Pro’s Add-On
If you really want to think like a drainage pro, add these three steps:
A. Soil Probe
Stick a screwdriver or soil probe into the low areas. If it goes in easy and comes out wet, your soil is saturated and likely compacted.
B. Utility and Neighbor Impact
Is water coming from above-grade utilities? Is a neighbor’s yard sloped toward yours? Shared water is common in Maryland neighborhoods.
C. Sump Pump Output
If you have a pump, find the output. If it’s dumping within 10 feet of your home, it’s time for a better discharge plan.
FAQs: What Homeowners Ask After a Storm
Q: Is it normal for my lawn to be wet the day after rain? A: Depends on the soil. But if it’s still soggy after 24–36 hours, there’s likely a drainage or absorption problem.
Q: Why does my neighbor stay dry while my yard floods? A: Slope, soil, and systems. We evaluate all three.
Q: Should I fix this myself or call someone? A: If you can see the problem and the solution is obvious, DIY might be fine. But if you’re guessing, call a pro. Drainage work is expensive to redo.
Q: What do you charge to walk my property? A: Nothing. Our drainage consultations are free. We believe in education first. Fix second.
Q: What if the puddle disappears before you come out? A: That’s fine. We know how to read the signs — dead grass, flow marks, washed mulch, exposed roots. Even if the water’s gone, the story is still there.
Q: Do I need a French drain or regrading? A: Maybe both. But we won’t know until we walk the property. Most yards need a mix of flow redirection and subsurface relief. It’s never just one answer.
Q: What do you look for first? A: Always the slope. If you understand where water wants to go, everything else falls into place.
Final Thoughts From Bob
Stormwater is predictable — if you know how to read the signs.
Your yard is telling you a story after every storm. You just need to walk it. Look for the clues. Learn what they mean.
That 5-minute diagnostic could save your foundation, protect your basement, and keep your lawn usable year-round.
Here’s a quick recap checklist for your next storm: – ✅ Check all downspouts – ✅ Follow the natural flow – ✅ Identify low spots – ✅ Inspect bed edges and hardscape borders – ✅ Find the water’s exit
