I am closing on a 100 by 400 +/- lot next Monday. I will be moving my business there. Before I can do anything I have found out I have to have an engineer do a site plan. I have topo maps already. There are no trees to clear. It looks to be pretty simple, the right front needs to be taken down 5 feet, a 3 to 1 slope needs to be put in along the front and down the right side, for about 250 feet, then shift to a 2 to 1 slope. A ditch needs to be put in along the bottom of the slope all the way back, and a retention pond about 70 x 60 dug in the back. There is a natural slope all the way back that will take care of the ditch flow. My dirt guy said they can do the job in about 2 days or less. My question is, how much should I expect to pay an engineer to draw all this up on paper and stamp it?
