San Diego Convention Center operators are projecting $1 billion in regional economic impact from 107 events scheduled to take place at the center during 2015.

In its annual business forecast, the San Diego Convention Center Corp. projected that events will generate $600 million in direct attendee spending, with total tax revenues topping $21 million.

Events slated for 2015 at the center include 66 primary conventions expected to attract more than a half-million out-of-town attendees. Total expected attendance for convention center events is estimated at 849,950.

The convention center has 16 medical meetings scheduled for 2015 – up from 15 a year ago -- projected to generate $421.7 million in regional impact and draw 161,000 attendees. The largest of those is the gathering of the American College of Cardiology, with 30,000 attendees expected to generate $65.9 million in regional impact.

That event is second only to Comic-Con International, with 130,000 attendees forecast to generate $135.9 million in regional impact.

Officials noted that projected figures for 2015 are expected to increase over the course of the year as more events are booked.

Due to factors including venue rotation by event organizers, the 2015 forecast numbers are below those projected a year ago for 2014, when officials said 111 events, including 70 primary conventions, were forecast to deliver $1.4 billion in local economic impact.

While visitor counts have generally been rising since the end of the recession, the center has yet to return to the peak of 951,618 attendees seen in 2008.

San Diego Convention Center Corp. is a nonprofit public benefit corporation created by the city to operate the 2.6 million-square-foot waterfront facility in downtown San Diego. The center opened in November 1989 and completed an expansion in 2001.
