State Rep. Melissa Conyears-Ervin said she will be a financial watchdog and seek control of the Council Office of Financial Analysis that looks at the fiscal impact certain ordinances might have on the city’s bottom line. Accountant Peter Gariepy, who unsuccessfully ran for county treasurer last year, vows he’ll run the office in a responsible but less flashy way. And, Ald. Ameya Pawar, 47th, said he would use the office to launch a public bank and campaign against income inequality.
