I made a quick map of the area under discussion. Hopefully it would be the Metro Health block. I know that the City wants to get them out of that building, and the Annex will be torn down in the near future for a "temp" surface parking lot. The new lot would be around 321 spaces. The lot at Metro Health is somewhere between 80-90 spaces.
I would rather see this section of Commerce developed rather than Houston St.
But maybe they are looking at a parallel twin along Laredo St. Eventhough, it would be an aweful idea.
This would be a great project for an area that currentlly has projects under construction and in the planning stages.
