"Curious if anyone's experimented with rain gardens or bioswales in flood-prone areas... seems like they could complement the geotextile approach nicely, but I'm not sure how practical they'd be in every situation."
We actually tried a rain garden on a client's property a couple years back—beautiful spot near a river, but flooding was a constant headache. The garden definitely helped slow runoff and looked amazing when the native plants filled in. But honestly, it wasn't a total fix. During heavy storms, the garden got overwhelmed pretty quickly, and we still had pooling issues near the foundation.
I've heard bioswales might handle larger volumes better, but haven't personally tested that yet. Wondering if anyone's had success combining bioswales with strategic landscaping or hardscaping elements? Seems like a combination approach might be more effective overall, especially if you're dealing with serious flooding risks...
We had a similar experience with a rain garden at our previous home. It definitely improved the aesthetics and helped manage moderate rainfall, but like you mentioned:
"During heavy storms, the garden got overwhelmed pretty quickly, and we still had pooling issues near the foundation."
We eventually added a bioswale along the driveway, combined with some strategic grading and permeable paving. Honestly, that combination made a noticeable difference. The bioswale handled larger volumes of water better than the rain garden alone, and the permeable pavers reduced runoff significantly. It wasn't perfect—really intense storms still caused minor pooling—but overall it was a worthwhile improvement.
One thing I'd suggest is carefully planning your plant selection for both features. Deep-rooted native plants seemed to stabilize things better over time compared to ornamental varieties we initially tried. Also, regular maintenance (clearing debris, checking drainage paths) was key to keeping everything functioning smoothly.
We went through something similar a couple of years back. Rain gardens look nice but, yeah, heavy downpours just overwhelmed ours too. Eventually, we dug an extra drainage trench lined with gravel along the side yard and redirected water away from the foundation. It wasn't fancy, but honestly it did the trick. Agree about native plants though—our ornamental grasses struggled, while native shrubs thrived without much fuss.

Yeah, that's a solid approach. Had a similar issue with one of my properties—rain gardens look great on paper but heavy rains just laugh at them. Ended up installing French drains around the perimeter and it made a huge difference. Agree on native plants too; they're tougher and adapt way better to unpredictable weather. Learned that lesson after losing some pricey landscaping...
Had water issues at my old historic place too—tried gravel trenches first, but ended up needing sump pumps in the basement. Curious if anyone's found a less intrusive fix that actually holds up long-term...?
