Why should it be in suspended animation until Judgment Day when all the pieces fall into place to "redevelop the entire legislative precinct"?
If you work on it piece-by-piece then you run the risk of creating a diverse and colourful multi-use district that would seem as if it had arisen organically from the city that surrounds it. Once that happens, there's really no way to transform the area back into the overplanned "designed-by-committee" abomination that it should have been.
