This is not a new or inconsistent stance. When the ballpark EIR commenced in 2006, these very same residents had plenty of concerns about traffic and light and noise impacts. Back then, the ballpark was expected to hold up to 45,000 people with a height over 200 feet including light standards. Cisco Field is expected to hold 32-35,000 and based on drawings, would be much lower than 200 feet thanks to its two-deck design.
NIMBYs have more to worry about than just a ballpark. Diridon Station is eventually going to be a massive transit hub with BART running underground and HSR running above ground. Preliminary sketches of the HSR platform could have its canopy be 100 feet tall or more. High speed trains also make noise, though it's not of the diesel engine variety. The whole Diridon area is slated for medium rise development, which means lots of future construction, including piledrivers. Adobe bought the nearby San Jose Water Company land and plans an expansion at some point.
Proponents of the ballpark point to all of the naysaying regarding the arena's development. The arena didn't destroy either Shasta/Hanchett or the further away Rose Garden, and it actually led to redevelopment of downtown and the Cahill Park neighborhood immediately west of Diridon Station. A ballpark promises to bring 30,000 people into downtown 81 times a year, at many times simultaneously with a 17,000-person HP Pavilion event. A resident's approval may simply depend on whether or not bringing that many people into SJ is considered a good thing. San Jose isn't forever gripped in a small town/big city conundrum as Fremont is. San Jose's inferiority complex is palpable and pols for the last 20 years have tried to address it in numerous ways.
Herhold's status as a Shasta/Hanchett resident adds a twist. He acknowledges that so far, residents are majority opposed. At the end of his column, he proclaims his support of the ballpark, as long as it's a good deal for the city. He noted the success of HP Pavilion and its effect on the stretch of The Alameda that runs north of his neighborhood. I live closer to SJSU, so I don't have a stake in Shasta Hanchett. However, I may move there at some point to raise a family and take advantage of the schools there. It's also not a bad place if, in the future, I want to walk with my growing child to an A's or Sharks game. That said, I'm with Herhold on the ballpark issue. If the city can make a good deal, let's do it.
Note: I originally posted this without mentioning the neighborhood that would be most affected by a ballpark: Delmas Park. It's directly under the approach to SJC airport. Sadly, Delmas Park isn't a moneyed enclave like Shasta/Hanchett or the Fremont neighborhoods. It's naturally going to be more difficult for them to have a say in all of this.
