Somewhere I've got a study relating to the Matagorda launch site, but I've never been able to run down a plan of the proposed facilities.
I've read that too... Look for the "Spiro T. Agnew Space Center" or something to that effect...
I live about 50 miles or so from Matagorda... (BTW it's incorrectly positioned on the map-- Matagorda is MUCH further up the coast and closer to JSC in Houston (maybe 75 miles apart or thereabouts). I used to work at the nuclear plant that was built on the site they were proposing, basically, or very close to it. It's just south of the city of Bay City, Texas, in Matagorda County, TX. It wouldn't have been over an hour or so west of Johnson Space Center in Clear Lake, TX...
In fact, one of the proposals I was reading about for a commercial rocket attempted a launch from the Matagorda Bay area... unsuccessfully...
At the time, they were planning to completely scrap KSC and the SLC-39 infrastructure, including the VAB, pads, MLPs, crawlers, everything... start shuttle off with a clean slate. IIRC they were planning on going back to either horizontal integration and roll out to the pad via rail carriage (like Soyuz, Proton, N-1, Energia, etc) or 'stack on the pad' much like Saturn IB had been done. OF course this was pretty early in the shuttle design cycle, and those plans were in flux even as they were being looked at. ET's could have been easily transferred the 450 miles or so from Michoud to Matagorda via the Intercoastal Waterway, which passes quite near Clear Lake en route, and continues from across Galveston Bay, hugging the coastline, until it enters Matagorda Bay, and then continues onward down the coastline to the bay at Port Lavaca and on down to Padre Island at Corpus Christi (naval base and industrial area) and on down to Brownsville, TX. IIRC, they were gonna fly a "hooked" trajectory out over the Gulf of Mexico to jettison boosters (pressure fed at the time??) and then recover them via ships, bringing them back to the launch site via Matagorda Bay...
It was an interesting proposal, but it would have cost HUGE sums of money, and of course it was POLITICALLY untenable, because it would have meant shutting down KSC altogether. In the end, the reuse of the existing Saturn infrastructure at KSC was seen as the "obvious choice" and saved billions in not creating an entirely new space center out of rice fields and cattle pastures along the upper Texas coast...
