A descending grade at the rate of -4% intersects another grade ascending at the rate of +8% at station 2 + 000, elevation 100m. A vertical curve is to connect the two such that that the urve will clear the boulder located at station 1 + 980, elevion 101.34m. Calculate the following: a. length of the curve b. the statio of the location of a sewer to be laid c. elevation of the station where the sewer is to be placed.
