[29] After approving the concept in 1961, it took until late 1963 to finalize plans since there was issues with how to design an adequate sewage system.

[31] St. Anna was interested to join since its school was being closed but wasn't invited to the first meeting since it was in a different diocese; the organization decided to decline since it arrived too late in the planning.
