Concern is growing among some local officials over the city of Buffalo's proposed budget as Democratic mayoral primary heats up.

Erie County Executive Mark Poloncarz says his office reviewed Acting Mayor Chris Scanlon’s proposed budget and found a number of discrepancies.

Poloncarz is a member of the city’s fiscal stability authority required by state law. In a letter sent to the authority’s executive director, Poloncarz raises concerns with budgeting based on items that are not guaranteed such as the $26.5 million sale of the city’s parking ramps to a new state authority that still requires approval from the state legislature.    

The county executive also claims some revenues are overestimated while others are under-budgeted.

Spectrum News 1 has reached out to Scanlon for a response to the county executive and his office says a statement will be released this weekend.

The city’s comptroller, Barbara Miller-Williams, and state Sen. April Baskin have both raised similar concerns about the proposed budget.     

Scanlon is proposing a $622 million budget with an 8% tax levy increase. The acting mayor is currently running in a six-way Democratic primary for mayor against state senator Sean Ryan, who is endorsed by Erie County Democrats, former Buffalo fire commissioner Garnell Whitfield, common councilor Rasheed Wyatt, community organizer Anthony Tyson Thompson and nonprofit founder Michael Gainer.
