SARANAC LAKE — If this village becomes a city, it could cost surrounding towns and Essex and Franklin counties more than the Saranac Lake Area Government Restructuring Committee had initially estimated — in some cases much more. The latest report from the committee’s consultant, Tim Weidemann of Fairweather Consulting, was delivered to GRC members at a meeting last week. It addresses concerns raised by town officials at a meeting in July that the fiscal impact of the city option on their taxpayers outside the village had been underestimated in the committee’s initial report. Town officials had also questioned why the GRC didn’t consider the possibility of the city pre-empting a portion of county sales tax revenue in its fiscal analysis. The new report shows town of Harrietstown taxpayers who live outside the village of Saranac Lake would see their property taxes increase 17 percent if the town tax base no longer includes the village.
