I know schools like SHG and MC have invested heavily in getting home fields on campus in recent years and moving away from longstanding, larger publicly owned rental facilities.
I see the nursing home adjacent to JCA is set to be demolished in the near future. The Herald News mentioned that since the Sisters of St. Francis own both JCA and the retirement home that JCA would have right of first refusal to purchase the property. It is a large property with lots of possibility. I have no inside knowledge and am merely speculating, but if the school could fundraise and find the capital, then that could be the property that allows the construction of a home facility for football, soccer, etc.
Memorial Stadium has been home for over 70 years and the big game atmosphere there with 10,000 in the stands is hard to give up. But high school crowds are fractions of what they used to be and a home facility would certainly be tempting. Partnering with youth football, soccer, or baseball organizations or even the park district could help offset the cost if there is mutual interest. If not, I am sure there would be rental interest once built.
Once again, there is no news here other than that the property adjacent to JCA will be demolished and it sounds like the school has dibs on the property if it has interest. To buy or not to buy will certainly be an interesting decision. The school also owns lots of property behind the school which is largely open space for lower level practices/open space but it is pretty far off the beaten path. The nursing home property would offer a closer walk from the school and a more prominent location to house a sports facility.
