Austin residents benefit from a recently finalized conservation easement on Shield Ranch, which protects 202 acres of land crucial to the Barton Creek watershed. The City of Austin and the Shield-Ayres-Bowen family completed the agreement in 2026, effectively ending the 2018 Water Quality Protection Lands Bond program.
Why it matters
This deal prevents large-scale residential development on land that contains about 10 percent of the Barton Creek watershed, directly safeguarding a primary source of the city's drinking water. By keeping this wildland intact, the city ensures ongoing protection for both the Barton Springs water source and the habitat of the endangered golden-cheeked warbler.
The 202-acre easement is the final acquisition of the city's 2018 Water Quality Protection Lands Bond program, which shielded 6,830 acres in total. The ranch encompasses 6,600 acres of wildland and sits across 10 percent of the Barton Creek watershed.

Residents can rely on continued water quality protections for the Barton Springs drinking water source as a result of this permanent land restriction. The preservation of this 6,600-acre site maintains the local natural landscape and buffers the city against potential residential development density in the watershed.
