A proposal to develop 42 rental apartments on a formerly contaminated Plymouth waterfront site has won Zoning Board of Appeals approval.

By a 4-1 vote, the board recently granted special permits with conditions to Southern Dunes LLC for planned development at the corner of Water and Lothrop streets, just north of Town Wharf, according to Tracey McCarthy, the board’s administrative secretary.

Formerly the site of the Revere Copper & Brass industrial complex, the 1.66-acre property was abandoned until it was taken over several years ago by the Plymouth Redevelopment Authority, which coordinated its cleanup.
