Since the college was claiming that no elevations would change as a result of the project and that the grade would remain the same, map S-1 was supposed to represent both the "before" and the "after" picture of the site's grades and elevations. In fact, the map couldn't represent any real-world surface. What specifically are some of the differences between S-1 and the assessor's map?

There are a number of differences between the two maps. We've indicated some of them with red arrows. Remember, the engineer stated in the legend that he prepared this map (S-1) based on the assessor's map (B-8).
