Second Question: What does this site hope to achieve?
Answer # 1: To obtain a verified answer as to why low lying and narrow bridges along Shoal Creek don't experience routine overtopping.
Answer # 2: To determine at what point gravel bars under a bridge are deemed to be (i) an overtopping hazard and (ii) a fire hazard, as they have repeatedly enabled people to camp and build fires in close proximity to utility infrastructure.
Answer # 3: To determine if an exposed water utility pipe requires additional protection from potential debris strikes during flooding.
The discovery and answer(s) will be posted on this site to promote Shoal Creek, Engineering and to Keep Austin Weird.
