Don't neglect velocity restrictions that some water companies have. Around here it is 15 fps for underground.

Usually, and I emphasize usually but not always, a 6-inch lateral is adequate for a single hydrant but not if its 450 feet long.

I see where this particular project requires 1500 gpm @ 20 psi for 2 hours, what is needed to translate that into required underground/tap size?
