For over two hours on Monday, the Montauk Citizens Advisory Committee and a slew of other residents went over the problems that have dominated conversation here this summer, mentioning the “horror” of taxicabs and the need for code enforcement. They praised the new online complaint form on East Hampton Town’s website, which Betsy Bambrick, the director of the Ordinance Enforcement Department, who attended the meeting, said was unbelievably effective. Members also heard promising reports about new taxi legislation and town efforts to solve some parking problems.
