The Children's Discovery Museum wants the city to sign on the dotted line.

Officials with the museum are asking the city to formally approve its proposed move into the Mendel Art Gallery building, after the exhibits are moved to its new location beside Persephone Theatre.

Two years ago, the museum signed a memorandum of understanding with the city naming it as the preferred tenant. Now, it's asking for final approval on the arrangement.

The children's museum is currently running out of a leased space at Market Mall.

It wants to make the move when the art gallery moves to its new location in River Landing in 2016.
