Sump pump and a hose? Give them back their water.the neighbors property, again!
I'm on the side of a hill with a road above us. Water flows downhill even underground. Now that I have a perimeter drain around the carport/shop area the water that would build up against the East and south side of the building is now diverted into the drain and away. It was needed because the east side of the carport was 6' below ground level while the front was at ground level.
Because it was an open end carport there never was a drain before.
I'd suggest you install a perimeter drain around yours. get the water away before it reaches the garage.
+1Water diversion in residential developments has always been a problem and Calgary has bylaws against doing what you are experiencing from your neighbors yard.
A neighbour down the street removed the grass and replaced it with marble I thought for sure it would cause the bylaw officers to intervene but its still there and I have no idea if it causes water problems for the neighbours.
Maybe you can cut a few grooves in your floor to direct the flow to a sump basin or drain.What I believe may have happened due to the gradual upward slope of the houses to my west is they terraced the property to make a level back yard, having the cement walk way on thar side of the yard just made it worse, not allowing the water to drain into the ground
There is no going to the city or developers, these properties were developed in the early 80's. That ship has long since sailed. I suspect this has been a problem since day 1 of the garage being built
The water in the video is extreme, much longer and there would have been flash flooding all over the area.
When I have gotten water since all the the other repairs it was somewhat minimal, so I did not suspect that it was coming from next door, and just from whatever came down the path from my property, but with the volume of water yesterday I was able to clearly see where a good majority of it came from
This evening I'm going to scope out where his downspouts are located, could be that simple
Damming it up will just move the water down his path further, and undoubtedly against and possibly into the garage along the wall that I previously repaired
