An $80 million cancer treatment center offering a therapy only available in 36 other facilities in the country could be coming to the city. The announcement comes as the city and globe is roiled with the coronavirus pandemic, which has killed 1,331 Connecticut residents and led to mass unemployment. The project is expected to create more than 100 construction jobs over a two-year period, with at least 30 permanent on-site jobs and an annual payroll of $3 million once the center opens in early 2023, Crandall said. The company expects to pay around $613,000 a year in property taxes. State approval is expected to take several months, with city zoning approval needed afterward.
