Section 10: Recharging Zones and Watershed Boundaries Signs
Introduction
The Texas Department of Transportation (TxDOT) does not place
signage on state highways for Groundwater Conservation Districts.
Districts should not install roadway signs indicating aquifer
or watershed boundaries on the state roadway system. The only exception
are the Edwards Aquifer signs near the Loop 1/US 290 interchange
in Austin, which are required by a court order relating to the construction
of Loop 1.
Edwards Aquifer
TxDOT installed ENTERING EDWARDS AQUIFER RECHARGE AREA signs
at or near each entrance to each highway over the recharge zone
on Loop 1 (MoPac South) and US 290/SH 71. The signs were to inform
drivers and members from the public that they are over the recharge
zone of the Edwards Aquifer and that the area is environmentally
sensitive.
