Grading is confused since neighbor raised grade in corner about 4", extending east about 24', and Beverly raised her grade when pool was installed. Eric is planning to install 2-3" of pebbles in this area south of my garage/bonus room. I hope he is planning to install them so that the top of the pebbles will be at grade. That is what I always assumed; but upon measuring, it appears to be 2-3" above grade. I hope I am wrong.
