Boerne is expanding water capacity with the construction of a new line off Ammann Road. In 2023, the city entered into an agreement with Kimley-Horn and Associates Inc. for the design of the water main.

While the design was 100% complete, the city of Fair Oaks Ranch is planning an Ammann Road construction project, which will soften the southern corner of the roadway.

With this change, the portion of the line going along Ammann Road will need to be redesigned to accommodate the new road path. Boerne City Council approved the design Dec. 9.

The details

The water main will be dedicated to the Guadalupe-Blanco River Authority, serving as the second delivery point for the city. The new system will improve fire protection and water redundancy to the eastern portion of the city.


With the line connecting to the GBRA facility located off Ammann Road, design changes needed to be implemented to accommodate road construction planned by the city of Fair Oaks Ranch.

Boerne staff said the city of Fair Oaks Ranch agreed to reimburse the cost of design changes.

The amendment from the city of Boerne costs $26,990, and Fair Oaks Ranch will reimburse $24,260.
