SDSU seriously inflates attendance numbers, (as does virtually everyone else), so a 30K soccer stadium may be adequate.

Records obtained from the city of San Diego showing actual attendance figures for San Diego State football games over the past seven seasons indicate a venue about the size of what is being proposed for Mission Valley would have been adequate for most Aztecs games.
According to the city, SDSU averaged 25,617 fans through the turnstile for its six games last season at Qualcomm Stadium, well short of the 37,289 announced attendance that is generally cited as the team’s average.
The highest actual average attendance for SDSU football over the past seven seasons was 28,274 in 2011, and the team has drawn crowds of more than 30,000 to exactly one-fourth of the 44 home games it has played in that time.
Of the 11 games in the last seven years that drew more than 30,000, three exceeded 40,000. In that span, SDSU drew fewer than 20,000 a total of 21 times.
