SCARBOROUGH — Town Councilors on Monday gave initial approval to impact fees for development at the Haigis Parkway/Route 1 intersection and a reduced impact fee for development near Dunstan Corner.

Impact fees are charged to developers to fund improvements to roads and infrastructure.

The Haigis/U.S. Route 1 impact fee would charge developers $990 per vehicle trip estimated to be generated by their development.

The Dunstan Corner impact fee ordinance, established in 2006, would be reduced to $1,402. The town will need to figure out a way to reimburse businesses already assessed the higher impact fee, said Town Planner Dan Bacon.
