Guess it’s a balancing act—nobody wants to be the guy over-engineering a sandbox, but nobody wants surprise sinkholes either.
That’s where I get stuck. How do you know when you’ve done “enough” prep without just burning cash? I get that soil can hide issues, but if all the tests come back decent and drainage seems fine, is there an actual benefit to spending extra on things like more gravel or compacting deeper than code says? Or is it just peace of mind at that point?
I’m all for skipping corners that’ll bite me later, but I’m also not trying to pay for stuff that doesn’t really make a difference. Has anyone actually regretted NOT going the extra mile on a flat lot, or is it usually fine if you stick to the basics? Just curious where people draw the line before it turns into “over-engineering a sandbox.”

- Honestly, I wrestle with this every time. There’s always that voice in the back of my head saying, “What if you missed something?” But at the same time, budgets are real and nobody wants to pour money into the dirt just for the sake of it.
- If your soil tests are solid and drainage checks out, I’d say you’re probably 90% there. The “extra” gravel or deeper compaction above code—sometimes it’s just insurance, sometimes it’s overkill. I’ve seen projects where people went wild with over-prepping and it didn’t really add value, but I’ve also seen a couple where a little extra would’ve saved a headache (like minor settling near the foundation after a few years).
- One thing I do wonder about is how much local climate plays into this. Like, if you’re somewhere with heavy seasonal rains or freeze-thaw cycles, maybe that extra prep is worth it? But in milder spots, maybe not so much.
- Personally, I tend to follow code plus a little buffer—nothing crazy. If something feels borderline in the test results, maybe then I’d beef things up. Otherwise, I try not to let “what ifs” drive the budget.
- Curious if anyone’s had a situation where they stuck to code on a flat lot and regretted it later? Or maybe the opposite—spent extra and felt like it was pointless?
I keep thinking about that one job where we did everything by the book on a pancake-flat site, and five years later it still looks perfect. Makes me wonder if sometimes we overthink these things... Anyone else notice regional differences in how much prep people do?

- Seen both sides, honestly. Had a client who insisted on “belt and suspenders” prep—extra gravel, crazy compaction, the works. House is solid, but so are all the ones we did with just code + a bit of buffer.
- Climate’s huge. In places with clay soil and freeze-thaw, I’ll nudge folks toward more prep. But in dry, stable areas? Sometimes it really is just overkill.
- My rule: trust your soil report, don’t ignore drainage, and don’t let fear eat your budget. Overthinking can be the real cost driver...
Honestly, I added extra gravel and drainage on my last build just to be safe, and I’m not sure it made any real difference. The soil report looked fine, but I got spooked by a neighbor’s flooding story. Looking back, probably could’ve saved the cash.

I get where you’re coming from, but I’d actually push back a bit on skipping the extra drainage, even if the soil report looks good. Here’s why: those reports are a snapshot, and they don’t always account for what happens when you get a freak storm, or if the neighbor’s grading changes down the line. I learned this the hard way on my last place—thought I was being smart by just following the engineer’s minimums, but two years in, we got a “once in 50 years” rain and my crawlspace turned into a wading pool. Ended up costing way more to fix after the fact.
If you’re trying to keep costs down, there’s a middle ground. Here’s what I’d do next time:
1. Double-check the site grading before anything else. Even on a flat lot, make sure water has somewhere to go. Sometimes just tweaking the slope away from the foundation by an inch or two makes a bigger difference than dumping in more gravel.
2. Instead of overdoing gravel everywhere, focus it around problem spots—like low corners or where downspouts discharge. No need to blanket the whole footprint.
3. French drains are great, but only if you really need them. I’d walk the site after a heavy rain and see where puddles form before committing.
4. Don’t forget gutters and splash blocks—cheap insurance that keeps water moving away from your slab.
I get that it feels like overkill when everything looks fine on paper, but water issues are one of those things that can sneak up on you years later. Sometimes spending a little up front saves a lot of headaches (and cash) down the road... but yeah, no need to go overboard either.
Curious if anyone else has found that sweet spot between “just enough” and “way too much” when it comes to drainage? I’m still figuring it out myself.
