In May last year Atlantic City’s water authority hired advisory firm Acacia Financial Group to craft a concession agreement that would help the authority both retain its independence and stave off a state takeover of the city. Acacia Financial helped draft two 100-page-plus documents chock-full of inside information and financial details but just a few months later it abruptly ended its $20,000 contract with the water authority because it had accepted another contract – with the New Jersey department that held state-takeover powers. New Jersey, now tasked with plucking Atlantic City from its financial death spiral, is sitting on a detailed plan that would help potential buyers put a price on one of the casino resort’s few remaining assets: its water authority. What’s more, the plan calculates the future water-rate rises that might be possible for the authority. “Their analysis sets forth what a combined rate structure could be, given a concession model,” said Bruce Ward, executive director of the Atlantic City Municipal Utilities Authority said in an interview last month.
