Ullrich Vegetation Management Update
Thank you to neighbors who sent comments on the proposed vegetation management strategies for the Austin Water property at 812 Rocky River Rd. Austin Water developed the recommendations as a measure to reduce the risk of wildfire spreading to homes adjacent to the plant.
We recognize that there are competing values in keeping the lot dense for screening purposes and clearing vegetation for wildfire risk mitigation. Keeping the competing values in mind, Austin Water sought community input on the three proposed recommendations as an important step before making a final decision to move forward.
We received feedback from a neighbor indicating opposition to the measures and a preference to maintain the vegetation for protection against sound, vibration, visual, and light pollution. We also heard that the mow strip and shaded fuel break were considered excessive and unnecessary. A neighbor also asked about the wooden fence recently installed and whether it increased fire risk.
In response to community feedback, and with the agreement of City of West Lake Hills City Administrator, Austin Water will only move forward with one action item: the removal of downed limbs/trees on the buffer lot.  We also will keep vegetation mowed around the wooden fence to lessen any fire risk.
A contractor will be onsite over the coming weeks to remove downed trees and limbs. They will haul the materials off site. We expect this work to be completed quickly.
Thank you for your input. We appreciate the ongoing dialogue on issues important to neighbors and the water treatment plant.
