||Save the church. The archdiocese can never build that large of a facility that large again for the cost of repair. Save it, and rent it out for all the ring masses, graduations, concerts that tthey use to have there. While Holy Cross would be great there, it can still work with the church there.
There is no great commerical area around any high school. Anything around Brother Martin, Dominican, Ursline, Jesuit? SFC is aunique building that deserves to continue its existence.
