How to mitigate neighbors rain runoff from going into our pool
My neighbors backyard is about 4-5ft higher than ours. When we moved in a few years ago there was already a 3 ft retaining wall built about 4ft from the fence (see photo), but the dirt within is sloped and when it rains the water passes over the dirt and flows straight into our pool and yard, causing the pool to get dirty and the side yards to flood. Ive gotten a couple $30k quotes to install drainange and an additional step retention wall between the fence and existing wall.
What are our best DIY options? We’re thinking of making the existing retaining wall higher so its flush with our neighbors yard and adding some drainage between the fence and wall, but I’m not sure how practical that is or if that’ll create too much weight pressure on that tall of a wall. Adding an additional wall would mean we need to rip all the plants out and do a lot of digging.
