I have to second Tom's sentiment. We, in the industry, strive to be as pro-active and environmentally friendly as possible - especially since that is the first thing opponents will use in fighting any project. Then you get some bonehead that thinks he/they can save some money and try to pull a fast one. When they get caught, it gives everyone a black eye and opponents more ammo.
That's the first thing that jumped out at me when I viewed Derek's thread/photos of The Patriot project in Tulsa being designed by RTJII. None of those streams were protected and some were in valleys with pretty steep sides and 100's of feet of bare, disturbed ground around them. One spring OK thunderstorm and you could have a big mess on you hands.
Lets see, $150,000. At $3/linear foot for silt fence, that would enable them to protect 25,000 (almost 5 miles) of stream (remember a stream has 2 sides).
Tom, start at the upstream end, only work on a small section at a time. Depending on the aesthetic your trying to achieve, either seed and cover with a heavy-flow erosion control blanket or sod (you can also sod and go back later and change the grass type after the stream/banks stabilize. Use big roll sod if possible as it has fewer seams (where flood water can get in and undermine pior to rooting). By working on small sections at a time, say 100', you should be able to get a section completed in a day or 2, well within the ability to forecast rain.
At the downstream end, a siltation basin should be created to catch any silt that will be created as the stream "cleans" the bottom of the new stream. This works due to the fact that the velocity a channel of water will slow dramically upon entering a larger body of water. As the water slows, the heavier soil particles will drop out and settle to the bottom. This is how deltas are formed.
