Apologies to readers for getting this out later than expected.
The red parcel is the one remaining to be purchased that would be integral to building a ballpark. It is the site of Aeris Gas, which provides welding supplies and specialty gases. The location was formerly named ARC Gas Products, and over the years has merged with other Northern California locations to form Aeris. Last fall, national supplier Matheson Tri-Gas acquired Aeris. When the Diridon South site became a discussion topic in 2005, this business was considered one of the more difficult to relocate due to its specialized equipment and facilities. A move could be quite expensive. Will the city be forced to use eminent domain to acquire the land?
The blue parcels are only to be used to accommodate the widening of Autumn Street into Autumn Parkway. One of those blue parcels, the CarQuest Auto Parts store, is already vacant. Combined, the land is adjacent to Los Gatos Creek. In conjunction with the Autumn Parkway project, the creation of a greenbelt between the creek and the street would appear to be in order.
San Jose apparently has $22 million set aside for acquiring the remaining land. That would appear to be sufficient from a market value standpoint since the total amount of land is around 3 acres, and values at their 2006 peak were $7-8 million per acre - and have definitely dropped in the past 6 months.
There remains the issue of relocating the PG&E substation. The 2006 estimate for moving it south one block was $30 million.
