I would not support having the City pay for any renovations to RAP for the benefit of a private company.
If professional baseball makes financial sense, the team should build their own stadium. In fundamentally disagree with any public money being spent on professional sports.
if the city builds it and retains ownership of the stadium it can lease the building out to various tenants provided they offer a positive cash flow, allowing the city to get a return on its investment.
alternatively, the city can redevelop it and lease it at an appropriate rate, so as to provide the city with a suitable return on its cost, to a private operator who will manage and operate the building.
I don't have a problem with the city renovating the facility provided they get a return on the cost or at least break even. i can't fathom how the city redeveloping the grounds to suit baseball would do that however. the crowds aren't there and a diamond limits the attractiveness to a multitude of other sports that could bring in as good if not better crowds than a sub par semi-pro baseball team.
that said, the sports i am referring to are largely amateur anyways.
