But the death knell was a new set of cost estimates for the proposal a few weeks ago. Initially, the Loch Raven renovation was expected to cost $19 million, but that ballooned to $29 million, plus another $3 million to $4 million to build a replacement community center. The Cromwell addition's cost estimate more than tripled, from about $5 million to $19 million. The eventual re-opening of Halstead would have added some more seats, but how many, at what cost and when is unknown. In the meantime, the plan would have netted the county 289 new seats for about $52 million, or nearly $180,000 apiece.
