Last week in the Northeast we received about a foot and a half of rain in two days. They dubbed it the 100 year rain storm, flooding everything. Anyway, a client of mine bought a house in a new(10) year old development. In scattered areas of his yard, the soil, turf sank up to two feet from it's normal level. He wants me to bring in topsoil to bring it up to level and reseed. Now, my plan is this, dig out the turf in the two foot sunken area, put in 1 1/2" processed stone to 18", pound it down with a tamper and, place 6" of topsoil, seed and start fert. Am I right with this plan or am I missing something? It's measured out to approximately 115/cu. yds. I have an ASV-RC50 to move the topsoil and stone as well as two workers to spread it. Any thoughts an or suggestions would greatly be appreciated. Thank you in advance!
