Cost of architect and engineer for 100 lot subdivision?

[Jean Paul Valley]

We were quoted a cost of roughly 300k for a particular company to do the architectural and engineering work on a 100 lot 50 acre subdivision. I am still new to all of this but that seems extremely high, considering they are not actually doing the digging and constructing (that is being done by an excacation company). They are performing the plans, town approvals, specs, etc...Is it normal to get a quote that high? thanks.
