Bayou & Channel Crossings
Twenty-two watersheds drain this county through a network of bayous and improved channels, and nearly every utility route in the metro crosses one. That makes the bayou crossing the signature Houston bore: an engineered profile that enters outside the channel ROW, sags under the design scour depth, and exits clean on the far side without touching the conveyance the whole region depends on.
The governing reality is the Flood Control District and its channel rights-of-way: crossings of district facilities run on district review, with the bore profile, cover under flowline, and workspace shown to their standard. On navigable and regulated waters, federal review joins the stack. We scope those clocks into the schedule at quote time.
Technically, bayou crossings concentrate everything Houston ground throws at HDD — saturated banks, soft alluvium in the sag, fluid that wants to daylight up-slope. Annular-pressure monitoring, staged mud weights, and a written inadvertent-return response plan are part of the bore plan, not an appendix.
