Just a few days after the City Council Monday approved a 12-year tax break for the Christoph family’s latest proposed addition to the waterfront East Side property — as many as 1,500 high-end market rate apartments — that project received nearly $1 million from the state. On Thursday Gov. Ned Lamont’s administration announced it was spending $17.9 million around Connecticut to help clean-up contaminated sites for re-use. Steelpointe made that list and will receive $990,000 to further remediate the land where the housing is going. A power plant formerly stood on the site. The developers in a statement said the money will complete “the final stages” of $6 million worth of environmental work and they remain committed to the timeline they provided the council of a spring groundbreaking on the first 400 apartments.
