I'm looking for a solution to seeding or covering a slope with a 2-1 degree rise or approx 45 degrees. The slope is about 35 ft tall and 400 ft long and the bottom is even with a parking lot. An excavator sat at the bottom and raked the slope clean, now its to steep to run a dozer up and down let alone try to side hill hill it. Have 2 Ideas in mind but could use some thoughts or input on this. #1 - hydro seed it and run silt fencing the every 10' for the length of it. So I would have 1 silt fence at the bottom and 1 every ten ft going length wise up the slope. I think this would be the cheapest and easiest method. #2 Use curlex blanket and pin the whole slope. Expensive but would have less chance of the whole hydro process slipping in a down pour. Thats my biggest fear of hydo seeding is the loose dirt gets saturated in a down pour and washes the dirt and seed tack etc. from under the hydro seed. Can only tack the top. This area will never be mowed it only need to be stabilized and hidden from view. Its a commercial prodject so cost counts The bottom will be planted with arbs and austrian pines but they will take a few yrs to reach a height being able to conceal the slope. Suggestions, opinions, thoughts, help?
