While the Diridon renderings left many wondering about the little details, one major item we had no inkling about was the stadium’s capacity. Only vague mentions of 35,000 or 45,000 have been floated, but only briefly. So I figured that, absent a press release or backing documentation, I’d deconstruct 360’s model to determine the capacity. Keep in mind that this is my interpretation of what I’ve seen, so take it with several grains of salt as it is not gospel.
In doing this, several assumptions were made.
- Regular seating is normally 19-inch, 20 per row, with 2-4 inches on each side to accommodate standards. Aisles are at least 4 feet wide. A switch to 20-inch seats would reduce capacity.
- All seats are chairs with backs, no benches.
- Club seats are at least 24 inches wide with or without side tables, plus drink rails.
- Although not illustrated, a reduction in seating due to dugout placement is taken into account.
- ADA requirements nowadays recommend a dispersal of accessible locations, not just behind a section (this is why you see front row accessible sections in many stadia). This is not taken into account. However, I’ve been aggressive about providing ADA locations, so a reduction of seating as part of making such accommodations would be minimal.
- Bullpens are in center field.
- The field is sunken 25 feet.
- There are 40 suites and 40 minisuites. Club seats are up top. A club area in the grandstand behind the plate would reduce capacity slightly.
- Reduction of seating due to columns has not been calculated. Neither has a number of potential obstructed view seats.
- The press box has also not been factored in. It could displace up to 400 seats in the balcony.
- Terminology: Grandstand (lower level from foul line to foul line), Balcony (upper level from foul line to foul line), Outfield reserved (lower level left field), Outfield Balcony (upper level left field), Bleachers (lower level right field)
- The 1,500 figure for standing room comes from San Francisco’s maximum SRO limit for AT&T Park.
In my previous analysis, I had mentioned that I thought both decks would need more rows to make up for their limited length. To flesh this out, I’ve plotted two models. One has 40 rows in the lower deck and 24 in the upper deck. The other has 40 rows in the lower deck and 20 in the upper deck. In the second model, the last 4 rows have been eliminated in the main balcony level and the outfield balcony as well. The point of this is to illustrate how much of a difference capacity lopping off a few rows makes – in this case, almost 2,300 seats. Update 9/7 2:43 PM: Table updated to include an alternative with only 32,000 seats.
In the comparison, a third model is included. In it, the controversial right field bleachers, which in the 360 concept cut into the playing surface and reduce the RF power alley to a short 345 feet, have been significantly reduced. The result is that nearly 600 seats have been removed, but the alley is now 376 feet, though it quickly becomes 368 thanks to the cut-in of the bleachers.
Below is the original model.
Now here’s the modified version.
One thing mentioned in the comments is the lack of a service entrance to the field for vehicles and such. Since the field is sunken, there isn’t a way to incorporate a simple access ramp from right field. If the design moves forward, I would expect an entrance to be placed in the LF corner, where the multi-angle seating is situated. That would create a loss of up to 150 seats, but it would be space efficient and would allow for access from either the north (San Fernando Street) or south (Park Avenue) via the event level (field) service tunnel.
Note about the field dimensions: the original model’s quasi-rectangular shape (compared to a regular baseball field) would appear to be appropriate for fitting a soccer or football field. Unfortunately, the LF corner would cut into any such field layout, and the seats in the LF corner are terribly angled for either sport. Basically, this can be considered a baseball-only park.
Last item: the field dimensions show a 25-foot height in RF. However, this may actually be much higher if the home run lines are to be believed. The wall could be as much as 40 feet high, which would make it higher than both Fenway’s Green Monster and a similar, slightly taller wall called Arch Nemesis at Sovereign Bank Stadium in York, PA.
So, are you surprised by the capacities? What other questions or comments do you have?
