Section 10: Recharging Zones and Watershed Boundaries Signs

Anchor: #i1010348

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.
