Richard Gifford says that 5,000 cubic yards of tree waste from off-site locations was dumped on a pasture near his home at 2357 Old State Road. “The dumping violated town ordinances,” he told the board on Aug. 16. “It also disrupted the natural drainage systems, covered wetlands identified on the national wetlands inventory, caused groundwater backup on our properties, created a fire hazard, and created an environment for rodent infestation.”
