Interesting article in Catholic dash sf dot org on this.  Here is a quick quote which makes an important point:  

"The Archdiocese of San Francisco owns the seminary and its grounds. In addition to the archdiocese, the sponsoring dioceses are Fresno, Honolulu, Monterey, Oakland, Orange, Reno, Sacramento, San Jose, Santa Rosa, Stockton and Spokane." 

Quoting the article:  "Bishop Daly said that (decline in enrollment) is not a reflection of seminary administration rather a function of decisions by some dioceses to send seminarians to other seminaries as well as an overall drop in seminarians in some dioceses. Some such as the Fresno and Orange dioceses are sending men closer to home..."

Quoting +Daly:  "There are misconceptions about the program at St Patrick's Seminary--some see it as too conservative," Bishop Daly said. "The seminary is a solid program of priestly formation."  

"...some see it as too conservative."  Since when, I wonder?
