Everything starts with the soil. The program I use is to get around some very bad soil conditions and produce healthy turf and ornamentals. There is no topsoil I would want to use as fill/final grade material here. What is sold as "topsoil" here is not much better than the crap it is covering up. To do it right would mean installing a drainage system and a sand/organic matter mix.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
