(a) Cuts and fills greater than 150 cubic yards; or
(b) Cut or fill that is greater than five feet in vertical depth at its deepest point when measured from the natural ground surface; or
(c) Work that alters, diverts, or impairs the flow of water in the watercourse.
如按“a“， 150 cubic yards. 1 yard=0.9 m
1 cubic yard=0.914x0.914x0.914=0.76 cubic meters
150 cubic yard = 114 cubic meters
這是一個很大的量，不是幾車土就能運來的。
你自己的估算，或者送土公司的運量，是多大？
