The Planning Board is scheduled to hear an application Tuesday night that would create another 21 parking spaces for the 116-unit Metro Rahway project on Campbell Street and Elm Avenue.

The plan as approved previously would create a five-story rental development, including a ground-floor parking area of 85 spaces but another 21 parking spaces are sought on a particular lot within the development. The project had planned to use another 17 on-site parking spaces and 18 on-street spaces.

The applicant is seeking to amend an existing board approval for a four-story building on Blocks 149, Lots 1, 5, and 23-25. Lot 6 is sought to incorporate into the project and provide an additional 21 parking spaces and “other associated access and internal circulation improvements,” according to a certified letter to neighbors from Metro’s attorneys, Parsippany-based Pitney Day.

The Planning Board will meet at 7 p.m. in City Council Chambers, 2 City Hall Plaza. 

UPDATE: If the Planning Board approves the changes, Metro Rahway would have 120 parking spaces on site for the 116 units, plus 18 on-street spaces, according to Clay Bonny of East Hanover-based Heartstone Development, which also built River Place at Rahway “Lots 5 and 6 are adjacent to each other and we can expand the entrance from [West] Cherry [Street] to include parking on both sides of the entry boulevard,” he said in an email.
