[o, yes, roads and infrastructure get built, but the Navy is not paying for them--the rest of the Island is.]

WOW.  Do you understand how property and sales taxes work?  80% of Navy personnel and 100% of the supporting civilian jobs and contractors pay FULL FREIGHT on both property and sales tax - this pays for County roads and other infrastructure.  This is why tax rates are very low, Island Transit is free, and school assessments are bare bones.

Did you read my comment that the Navy has GIVEN water, wastewater and waterfront infrastructure to municipalities?  Apparently not.

Please, either (a) you are 100% naive and have no business conducting an "economic" study or (b) COER has continued to pay you to defend this quackery "study".
