YARMOUTH — Several neighbors have appealed the Planning Board’s recent approval of McKearney Village, the town’s largest residential housing development in 20 years, to Cumberland County Superior Court.

The board voted 6-1 in July for the 39-lot, 53-acre subdivision off Hillside Street despite widespread concerns among neighbors about the density of the project, the lack of a traffic impact study and the way town officials reviewed the proposal.

The lawsuit was filed Aug. 25 by Bruce and Suzanne Jones, Mary Dowd, Carroll Dunn, and Greg and Kara Salvadore. Their complaint charges that the board’s conditional approval failed to address traffic safety concerns and included several zoning waivers that violate state law.

Proposed by Mike Albert of Pownal, the subdivision calls for construction of 38 single-family homes; the 39th lot could be developed into a 32-unit multifamily complex.

The board satisfied some neighbors by allowing only recreational and emergency access to Sycamore Drive, a dead-end lane in the established Applewood Farm neighborhood off West Main Street.
