Philadelphia Chinatown community leaders and critics are speaking out against the 76ers’ recent announcement that it will cover a series of impact studies in the neighborhood for its planned $1.3 billion arena. Key details: The developers of the planned Sixers arena will reportedly raise funds and put the money into a pot that Philadelphia Industrial Development Corporation (PIDC), the city’s public-private economic development agency, can later use to hire consultants to conduct a series of impact studies related to the arena. The first two studies will reportedly have a total cost of $655,000 ($530,625 for the community-impact assessment and $125,000 for the economic analysis), while the cost of the third one is still undetermined, according to The Philadelphia Inquirer.
