KILLINGLY - After months of negotiations, the town and the state of Connecticut have hammered out a new lease agreement concerning courthouse parking areas that for the first time in more than 20 years includes an escalation rider aimed at keeping up with rising maintenance costs. The Town Council this month approved a 10-year lease agreement that will continue to allow court-related parking in the 50-space lot off Center Street directly across from Danielson Superior Court. The contract replaces a month-to-month agreement between the town and state Department of Administrative Services that began in July 2019 after the previous lease agreement expired. Under the new contract, the state will pay the town $9,000 a month for the first five years – the same amount as the monthly agreement stipulated – and $9,450 for years six through 10.
