As the Thomas Clark House was on its memorable half-mile journey through town Saturday morning, the trip was not without a cost. During the time the truck was hauling the 252-year-old house up Common Street and Concord Avenue to its new temporary home next to the Skip Viglirolo Skating Rink, a legion of town employees – from Belmont Municipal Light Department members disconnecting light posts and overhanging wires, Department of Public Work employees, police and fire – along with the town's tree contractor were working overtime to make sure the trip was completed without a hitch. All the while, Belmont Town Tresurer Floyd Carman was holding three checks from the house's new interim "owner," the Architectural Heritage Commission, to pay for the town's time as well as two sets of funds that were insurance, "just in case" the unthinkable would happen, said Carman. Carman said a total of $25,514 in deposits from the AHC – which came from donations from residents and others to support the move – were in the town's possession as the house was on the move. Carman said $13,014 of the total will be used to cover town expenses incurred by the move, including all personnel, overtime and material and equipment used in the process.   "There could be some nit-picking (on the final cost) because I did see some town employees from building inspection there who we didn't expect," said Carman. "But I think (the $13,014) is the right amount," said Carman. In addition to a check to pay for the town's contribution to the move, the AHC was required to write out a $10,000 cash performance bond to cover any unforeseen problems that may have occurred on moving day Saturday.  "They can come by to pick up their check," said Carman. Finally, sitting in a town-owned bank account is $2,500 that has been designated for "Dumpsters and other material" in case the town's Historic District Commission and the AHC can not find a permanent location and the town is required tear down and dispose of the house.
