1) I tried all the overlay methods just for grins. However, I found that the "intersect" method returned the same results as the "union" method, without having to select where the water buffer and the road buffer both equaled "1" and exporting the results to a new shapefile.
2) I used the "erase" overlay to remove areas that were inside the conservation areas.
3) There were a total of 79 features, with the largest being : 7,765,034.49356 sq. meters and the smallest being: 748.114463 sq. meters.
