Yep Sportsman, I do have a few more details:
The development partners for the US GP project in Austin have begun the detailed permitting process with their first submission to the planning authorities. Some interesting things have come out. The circuit will be built on the southeastern side of the plot. The intent is to avoid any construction in the vicinity of the high pressure gas line that crosses the property at the northern end. The plan is to encase the low pressure liquid HVL pipeline with concrete to protect and stabilize it. This will ensure safety and satisfy some critics of the development. There is also a secondary plan to relocate the low pressure lines, but most engineers agree that relocation is unnecessary.
The developers have chosen to submit their plans in phases, and authorities have agreed to that approach. The first phase is to be site preparation and grading. Of interest are the drainage plans and the waste water treatment plans. The intent is to make the site permeable and to use french drains and other techniques to channel the water to the desired areas. Paved parking areas will be at a minimum to avoid surface water accumulation and to avoid runoff to the surrounding areas. The intent is to use a combination of stabilized grass and gravel surfaces with perforated piping underneath to allow the water to soak in and to be channeled to desired areas. It will not be an unimproved grass field like many of us experienced in the past at Silverstone, but an engineered solution that provides stable ground at the surface with adequate subsurface routing. There is also a group of transportation specialists looking at a mass transportation solution.
Another interesting fact is that the planning is required to be reviewed by three different planning authorities: The Texas Dept. of Transportation, Travis County's Dept. of Transportation and Natural Resources, and the City of Austin (due to their extraterritorial authority). According to Joe Gieselman, Travis County's executive manager of Transportation and Natural Resources, "while all the agencies will have different priorities, instead of the applicant having to deal with all three parties, we can deal with it all at one time. We'll hear the same issues, and we can help them get through the process as quickly as we can." That is a refreshing approach. The three groups will act as a team to smooth out the process.
Tilke, the architectural firm handling the project, is using local engineers familiar with the geologic properties of the area. They are also familiar with the permitting projects and the submissions requirements. Without a doubt, this is the correct approach.
This is all of the text in the blog article, but there is a map and a picture of the site with a suggested circuit location at the blog:
