The Bypass will most likely have a planted buffer requirement along it, probably 40-50 feet according to the manicipality. That's the norm for most the work I've seen along main roads. Hate to agree with the negatives you're getting but I see it daily being a civil designer.
Trouble these days is the state of NC along with the manicipalities have added so much red tape over the years, it's going to come to a point where no one in NC can get anything done. It's slowly coming to a gridlock. There's so much say so to what you can do with your own land and the erosion control requirements are getting way out of hand. What used to take 6-8 months for approval is now lingering for years. Then there's the adjoiners say-so if there's any houses around it.
35 acres is tuff to develop with these issues. A person would have more luck with about 10 times that much land. But then comes the dime vs. dollar effect because 350 acres in NC is worth alot of money.
NC is becoming a money hungry communist state in my opinion. I just went through Durham's BS, tried to fight it and lost. Now I'm battling the state over other issues. And all came down over a neighbor reporting me over a fence violation - not being built to Durham spec - for them to come in and check me out under a microscope. And I just bought the place so everything besides the fence was inherited.
Of course I fixed my nicely built / fully painted fence to look like total hell with no rhyme in color for I just turned the picket groups around and the contour is now stair stepped and jacked up in the air in places with cut and paste boards throughout to fill the gaps. My neighbor is pissed as hell that it looks much worse now but guess what... It's now built to Durham spec.
And my neighbor has inherited an asshole. Yours truely!
Life is MUCH more interesting!
It's good to do your homework before you do anything now days around here. Every manicipality has a completely different set of rules. All it takes is a drop in to the local planning department with your plan in hand to see what you're up against. Although the streams and wetlands is a NC DWQ issue and pretty much the same across the board from the beach to the mountains. And if you go ahead with plan and beg for forgiveness later, the consequences are double fines and fees with more stringencies.
B.T.W. that one stream looks like it is being disturbed already by someone upstream. You could stir some serious shit with a phone call to NCDENR.
Good luck!
