|Spoils fill areas shown on Civil Plan UP1: 10,100 cy + 5,900 cy ||16,000 cy|
|Spoils fill NOT NOTED on plans: 49100-16,000 cy|
destined for the service driveway and
berms at southernmost area of the site
|33,100* cy |
*Will the service driveway and berms around parking actually absorb twice as much in spoils as the designated spoils areas? This does beg unanswered questions about the ability of the site to accommodate all of the spoils.
Topsoil removal and replacement
Note that the amount of dirt to be excavated and repositioned on the site is much larger than just the cuts that produce spoils. ~ 2 feet of topsoil must be removed in all areas to receive spoils, stored on the site and then recovered over spoils.
From the site plan it appears that about 7 acres (Includes some guessing around the winery) will have to be stripped of their topsoil and replaced after the distribution of spoils.
|Removal, storage and replacement of 6.9 acres of topsoil, 2 feet deep|| 22,300 cy|
Total amount of earth being moving around the site
49,100 cy spoils + 22,300 cy topsoil
In all about 71,400 cy of topsoil and spoils must be moved around the site. To put that into perspective, if the earth being moved around on the site were piled on a football field (including end zones) the height would be 33 feet, the height of a 3 story building.
Football field = 57,600 sf
Dirt piled 33 ft high: ~ 71,400 cy
Another way to put that amount of dirt into perspective: it is a volume equivalent to 3.25 Napa County Buildings.
County Building = ~ 16,500 sf
If 36 ft high: ~ 22,000 cy each
