By July, the three stories in the 70,000-square-foot building facing Howard Avenue and Cherry Street will have been transformed into a 725-student charter school. It’s one part of an ambitious brownfield remediation and revitalization project Flocco and his firm Corvus Capital Partners have undertaken in the city’s West End with home-development partner The Pacific Companies. The project is being financed by low-income housing tax-credits, state and federal historic tax credits, different forms of tax exempt bonds, money invested by the developer and federal Finance Adjustment Factor funds, distributed from the U.S. Department of Housing and Urban Development to states for use on affordable housing projects.
