hi there, I have a question. I'm adding a 497 sq ft bedroom in Los Angeles City. I was just told by the arch that I need a civil eng to draw drainage plans to re-route water from my backyard "up" to my front yard approx 6-8 feet higher then my backyard and about 300+ feet in length. I have talked to several civil engineers. Every single one of of them are completely blown away that I have to do this and to top it off NONE of them agree to take on the job because they don't want to assume the responsibility. Who wants a sure to fail job, right? I was told that even if the water actually gets all the way up to the street with a sump pump that it may flow right back down my driveway and back into my yard again but this time it could FLOOD my garage because rather then the dispersement of water that is naturally happening, I'd be collecting ALL the water from my entire backyard and putting it into one area to flood another. I'm just blown away at how the city would want to change the natural progression of the rain water and make it flow upwards? Any suggestions on how to deal with public works or the city on this or what other options I have?
