Yes, an overpass would have been sure to generate some TOD activity; and would have created a merging of the Stockyard Development with the Tarrant Express development. All parties would benefit. The recently announced Swift Stockyard Hotel and other private investment would have a seamless connection to the Airport and to Downtown. The reality seems clear - FWTA and DART refuse to allow TOD along this project unless they have 100% control. North Side Station will be a carbon copy of the Richland Hills Station, but with even less use.
Hopefully, there will a rethink of this idea and the City of Grapevine, Fort Worth and the Stockyards will better served by Tarrant Express to correct this missed opportunity.
We can only hope that eventually a transit line will be put in between Downtown and Stockyards/Meacham.
I wonder if the city could put some of their mixed-use, urban village zoning in effect for the 28th and Decatur area (or preferably along 28th between the station and 35W), and if so, if property owners in the designated area might be able to "circumvent" some of the issues FWTA has with TOD that way. Provided, though, that the city is not bound by a contract preventing them from doing that.
Otherwise I agree with renamerusk in that the North Side Station will be quite underutilized. If you could get a bus line providing a direct connection between the station and the Stockyards, you might be able to get tourists to use the North Side Station. But first, the area surrounding the station would need to look more attractive.
TODs are rarely built and open for business by private investors before the "Transit" component is built and open for business. I have no idea what the zoning will be around every station. The FWTA has no power over local cities on how they zone properties or neighborhoods. I wish advocates stopped suggesting they do. Take that issue to your local city hall.
The property in downtown Fort Worth surrounding the T&P Station and the ITC aren't owned by the transit agency. The land surrounding the property in downtown Grapevine and at DFW Airport aren't owned by the transit agency either. Some land adjacent to other TexRail and TRE stations are - usually for their own buses to use and to provide parking for their customers. Most business in Fort Worth also provide parking for their customers as well. Even most mixed use properties provide enough parking to attract businesses and residents. There's nothing unusual about having parking near train stations, even airports have parking. Do you really think DFW Airport could survive long without lots of parking?
Where's the advocacy for having mixed use properties on DFW Airport property immediately adjacent to the airport's passenger terminals instead of parking? Will it be too noisy? Well, trains can be noisy too.
