WATERFORD — The town’s road foreman, Lisle Houghton, and the second most senior member of the Waterford road crew, Wade Baillargeon, both have resigned. Select Board Chairman Gary Allard on Friday confirmed the two most senior road crew members quit. The select board discussed the resignations on Thursday night during an executive session at a special meeting called for other matters. The two employees quit several days apart earlier in the week. The departures were effective immediately and the pair are using time due them, said Allard. Allard said both the men were on the town’s road crew for more than 20 years.
