Thanks for taking time to look at the album, Joey! I've already come across a few of Chuck's videos; they're great! The sump pump like he did looks to be basically a french drain that has to drain uphill. In my case, the house and backyard are uphill from the street, so I'm hoping I can accomplish proper drainage without a costly pump.
For now, let's go with a tentative/theoretical plan that a French drain could do the job. If a French drain doesn't suffice, I imagine I could add a pump to the French drain system down the road. Let's also tentatively plan that my chill neighbor won't mind me destroying his driveway for a few days.
EDIT: Before we get to photos, let me just say WELCOME TO BEAUTIFUL, SUNNY OHIO!!
Here are my primitive MS Paint and google map sketches of the property and water flow. Let me know if they're unclear. The dotted green line is the proposed route for whatever kind of drain line gets installed. It originates on the east side in my neighbor's and my backyards and flows west to the street, along my southern property line, presumably in the neighbor's driveway.
FYI: My lot is approximately 1/4 acre and 48 x 228 ft
I need to figure out the easiest way to determine the overall slope to see if it's enough. Advice on methods? Also need to figure out if my neighbor will let me trench along his driveway (the gravel one). Otherwise, I think I'd have to dig up my driveway (expensive enough that I'd probably rather move) or (if "lucky")
only have to kill all the shrubs and trees along the property line on the opposite side of my driveway from my house (north). I actually wouldn't mind removing all that overgrown shrubbery, except for the one pretty pine tree and the ridiculous amount of added work.
Here's a list of questions/concerns from last night's brainstorming session (in no particular order). I'll come back and insert corresponding pics later. For now, here we go:
Will the neighbor let me trench his driveway? Obviously I'd leave it better than I found it. And I'd actually be helping drain his flood-prone backyard too.
My house and the neighbor's driveway. We are looking slightly uphill here:
From my kitchen during flooding. At least the patio slopes away from the house, although the basement does get minor moisture, mostly from this (east/back) side of house:
From my second story. Notice the pool on the left.
notice the massive shrub/trees, these are right along the proposed trench line:
Is it necessary to take the water all the way to the street? i.e. Could I just put some sort of underground gravel pit (dry well?) and or rain garden in the backyard behind the garage, or would it eventually overflow into the garage anyway? Without any education on the topic, I think the soil couldn't possibly drain fast enough, and it would be pretty frustrating to do a bunch of work and still have the garage flooding. My backyard is definitely the low spot between me and all the 5ish surrounding neighbors.
If I'm running drains to the street, how do I get it there? Tunnel under the sidewalk? Just terminate in the neighbor's driveway? Would I have to remove sidewalk?
Here's a south-facing view of neighbor's driveway at the street. Note, most of that water in the street came from my driveway slightly uphill:
my driveway that always has water flowing from under it:
Will the roots from those arbor vitaes (the big green bushes) be too much for a rental trencher to handle? What about the gavel driveway (presumably with bricks and other trash/building material under it)?
From west/street side:
From east/back of lot:
How close to the house can I get? Is there any risk of damaging my foundation? If I have to go in (not alongside) the neighbor's driveway, will the weight of their cars compromise the drain pipe or the function of the system?
In my small section of backyard between the patio and basketball hoop, there appears to be some sort of drain or catch basin. What is that and where does it go? You can see a few bricks in a hole at the bottom of this pic:
Can/how should I connect drainage from the aforementioned section of backyard to the larger section that will come from the section of yard from behind and beside the garage? Again, those massive shrubs to the right in this pic will interfere. Let it be known, I don't care if they have to be cut down. Hopefully I won't have to pay for an excavator or stump remover though:
If I do drains/catch basins without pumps, is standard 4" pipe enough to drain this size yard when all the neighboring yards are also sloping towards mine? For reference, the pics of the deep flooding were when it rained nearly 3" in 3 days. The flooding is not that bad every time it rains.
Can I run power to my garage during this project? Able to share a trench with the french drain system well below the power conduit?
Can I get away with this project without any permits? My concerns would be:
1. Encroaching on neighbor's property.
2. Where it terminates at sidewalk/street.
3. If I run power to garage while I've got the trencher rented.
So, there's some of my thoughts thus far. Anyone have answers? Anyone think of questions that I'm forgetting? Ready, go!
