Earlier this week I did some calculations on the buildable footprint for a ballpark at the Peralta CCHQ. I gave the footprint an extra buffer on the channel, which dropped the footprint to only nine acres. Since then the always useful Planimeter to calculate a more realistic 10 acres, including the city-owned lot in the southeast corner next to 880 and the old WPRR rail easement. Without those two parcels, the acreage drops to 8 acres, smaller than Target Field. Even 10 acres is small for a park these days.
Size isn’t the only challenge at Peralta. Thanks to its location relative to Lake Merritt, the channel, and downtown, there’s only one way to orient it for optimum view or backdrop that includes the DTO skyline and the lake: north. It would theoretically be better to orient it northwest, but as we already know, that’s generally frowned upon. Three open-air venues currently face north: Progressive Field in Cleveland, Coors Field in Denver, and Petco Park in San Diego. Peralta shouldn’t be difficult to implement with a northern orientation, as long as they properly address a north-facing park’s biggest weakness: glare or light reflecting off the batter’s eye.
This ballpark overlay is a generic version originally done for a multitude of sites 10 years ago, transplanted to Peralta. It could seat 32-35,000, with more space for standing room. It provides a solid 100-foot wide buffer around the grandstand in foul territory, which conducive to spacious concourses and additional square footage for offices or retail. It also allow for three large entry plazas. The main gate would be in left-center, accepting the majority of fans coming from downtown. Another plaza would be in right field at the corner of 5th Avenue and East 8th Street. The last one would be behind home plate and would be used mostly by VIP’s.
Not illustrated are potential restaurants along the channel which could be used 365 days a year, or bars built into the ballpark that could open either only during the home games or all year-round. There’s quite a bit of space to put in a children’s play area in right field, or picnic areas in left near the channel. Best thing about this orientation is that all of the outfield amenities could be kept at grade or field level.
The site is at a nearly uniform 10′ elevation. It’s adjacent to Lake Merritt Channel, which recently benefited from beautification and flood control projects made possible with Oakland’s 2014 Measure DD funds. To understand the potential impact of a ballpark, it’s worth looking at the other three waterfront ballparks and how the addressed the shoreline.
Pittsburgh’s PNC Park and Cincinnati’s Great American Ball Park are located on active rivers, the Allegheny and Ohio Rivers, respectively. SF’s AT&T Park is not truly on San Francisco Bay, but rather on an inlet, Mission Creek. Although there is a small ferry terminal at the park and the Lefty O’Doul drawbridge over Mission Creek, the waterway itself is not particularly busy at all, allowing for the use of kayaks, paddle boards, and other small personal watercraft on the water along the ballpark’s promenade. A Peralta ballpark would maintain at least a 100′ buffer to the channel, making “splash hits” unlikely thanks to an estimated 500′ distance down the left field line to the water. PNC & GABP created partial levees facing the water.
There doesn’t appear to be space for food trucks or other temporary or portable installations in the ballpark. I could see the A’s petitioning to close East 8th Street on game days in an effort to create a Yawkey/Eutaw-type environment outside the park. If that happens, there’s some very usable space for parking food trucks on E 8th.
The A’s have been hinting at a two-deck design for some time, which if implemented should conserve height. That creates a potentially uncomfortable situation where the main concourse along the third base line could be aligned with 880. To prevent this the façade would not be open air, with windows working in conjunction with concrete to mitigate highway noise.
Those are my initial thoughts on optimizing the Peralta site for a ballpark. They’re subject to change as we get more information on the site. If Peralta is selected as the future ballpark site, I look forward to seeing how creative the A’s and HOK are on evolving the vision at Peralta.
