Here is the job. It is a new house with no lawn. The back yard, where they want to put their money first is a total of 11072 square feet. 1. The ground is rough and not a smooth surface. Should I knock all the high spots level and then put 2 inches of good top soil on top before seeding? This is one part of the job part A Part B Along the perimeter of the back yard they need tall coverage because they have a major highway behind them. The perimeter where they want the trees is 275 feet long. I was thinking of using blue spruces to use as cover. My questions for all of you guys with more experience than me is, (I will have to rent all big machinery for this job..i.e. kubota) 1.where would you start on this job? 2. what type of evergreens are best for a northeast climate and providing coverage from the highway? 3. How far apart should the centers of spruce or similar tree be from each other? 4.What would you charge? Thanks eveyone!!!
