1- the PC of a curve is at station '15+25.00. The delta angle is 30 degrees and radius is 475.00 feet. What is the station of the PT of the curve ?

2- The difference in elevation between station 2345+22 and station 5734+23 is 19.34 feet. What is the % grade between the stations ?

3- A grid (10 x 10) is shown on the following page representing topographic elevations in feet on a site.

- Draw contours of elevation at 5-foot intervals, starting at 45 feet, across the grid?

- If the material above 80 feet in elevation must be removed from the site, how much volume of material must be moved in cubic yards?
